BYD promised them very happy by putting very advanced ADAS in very cheap cars. Until the RAM crisis came

April 30, 2026 by usatoday24

In recent years, BYD had turned its brand new advanced driving system into one of the biggest arguments to confront Tesla. And having this type of technology in affordable cars can be attractive to the consumer, but it has a cost that other companies can hardly absorb. BYD thought so, but the RAM crisis It has stopped him, and the context is now much more complicated. Prices go up. BYD just announced in China a 21% increase in the price of the ‘DiPilot 300’ option (basically its “God’s Eye” in its version with LiDAR), which goes from 9,900 to 12,000 yuan (about 1,560 euros). The company justifies the measure by the “significant increase in global storage hardware costs.” In other words, DRAM memory and storage have become so expensive that they can no longer absorb the cost without passing it on to the customer. Until now, no major manufacturer had so explicitly linked a price increase to the memory market, according to collect South China Morning Post. In detail. The ADAS Modern ones (and especially those that integrate LiDAR like those from BYD) are very demanding on memory. They need high-performance chips to process LiDAR point clouds in real time, run driving models, and store route data. The problem is that this same type of memory is being absorbed en masse by artificial intelligence data centers, which account for most of the global production of DRAM and NAND. The prices of these chips have entered what analysts call a “supercycle,” with increases that according to TrendForce are around 55-60% in conventional DRAM this year, but that in premium automotive segments (which also use DDR5) have reached up to 300% in free market price. A problem of scale. BYD’s colossal deployment makes the problem especially bulging in its case. The company has installed your “God’s Eye” system in more than 2.85 million vehicles as of March 2026, generating approximately 180 million kilometers of driving data per day, according to own data of the signature. At that scale, every extra cent in memory multiplies into millions. On the other hand, BYD closed the first quarter of 2026 with its worst net profit in three years: 4.08 billion yuan, a drop of 55% compared to the same period of the previous year, according to figures published by the company. In this context, maintaining prices without making a move has become unsustainable for the company. They are not alone. Chery, Xiaomi and the Huawei Aito brand prices have also increased on models with similar advanced driving systems in recent months. William Li, founder and CEO of Nio, counted in January that the biggest cost pressure of the year would not come from raw materials, but from memory. What changes for the buyer. The founding promise of “God’s Eye” was that autonomous driving would no longer be an expensive privilege. As we counted almost a year agothe experience of the system on the highway (even in the most economical model, the Dolphin Surf/Seagull, which sells for around 9,000 euros in China at the exchange rate) was genuinely impressive. Lane keeping was impeccable, autonomous lane changes were well executed and traffic management rivaled other premium range systems. BYD even planned to distribute it as standard in all its models, regardless of the price. Although that narrative is not dead, it is beginning to have nuances. At the moment, the version with LiDAR (the most capable) is already a payment option that has just become 21% more expensive. And now what. From Counterpoint Research they point that the blow will be uneven: low-end models simply will not carry this technology, and high-end ones have less price-sensitive buyers. The greatest impact falls on the mid-segment, where BYD’s value proposition was most disruptive. As the markets are, we will have to wait to find out what direction the company finally takes.

They promised us that 20 minutes of sparking was equivalent to 4 hours in the gym. Science says it’s more complicated

April 11, 2026 by usatoday24

Since humans became aware of the existence of electric current, they have tried to apply that power to their own body. As detailed in a report by The Wall Street Journalthis fascination goes back a long way: from the ancient Roman belief in the healing impact of torpedo fish, to the famous vibrating belt machines that promised to sculpt silhouettes in the 1950s. Today, the industry fitness has taken it a step further with whole body muscle electrostimulation (WB-EMS). The concept itself seems straight out of a science fiction movie: users don a wet suit covered in electrodes that delivers simultaneous shocks to major muscle groups for about 20 minutes. The marketing hook is irresistible, as these strength and bodyweight training sessions are sold as the ultimate shortcut to replacing hours of sweat in the gym. On social networks, dozens of influencers They upload videos doing squats and arm lifts while wearing this bionic suit. But, beyond the aesthetics and the promise of a toned body with little effort, what is true in all this? From the clinic to global fashion The technology behind electrostimulation is not a recent invention nor was it born in a trendy gym. Initially, it was used in hospitals and rehabilitation settings for a strictly medical purpose: to relieve pain, prevent muscle atrophy in bedridden patients, and improve circulation. However, in recent years, it has experienced explosive growth as a business model. fitness. The data is there. On the ClassPass platform, the number of centers offering EMS training worldwide increased more than 16% between 2023 and 2025. International franchises such as the French Iron Bodyfit plan to open more than 50 studios in the United States in the next three years, while the Californian company Body20 has gone from 46 to 67 locations nationwide since 2023. All this despite the fact that it is not an economic activity: classes cost between $40 and $100 per session. To understand the phenomenon, you have to understand how the experience works. The wet suit—water is necessary to conduct electricity effectively—sends electrical impulses directly to the muscle. This forces a greater percentage of muscle fibers to contract simultaneously involuntarily. As described by journalist Ellen Gamerman in The Wall Street Journalthe physical sensation is similar to that of receiving a call on a mobile phone in vibrate mode, with the difference that, in this case, “you are the phone.” Combined with core exercises, the level of muscle contraction makes the effort feel as intense as a high-intensity interval (HIIT) class. If you extend one arm without bending it slightly, the current can cause it to lock up completely until the trainer lowers the intensity of the machine. But who is attracted to this technology? Helge Guetzlaff, business development director of the German brand Miha Bodytec, joked in the American newspaper claiming that it attracts “a lot of lazy people.” However, Sabine Padar, owner of the exclusive Body Alchemist NYC studio, points out that she often has to convince her clients that spending more hours in the gym is not the only way to gain muscle. She insists that EMS sessions aren’t necessarily easier than traditional training, they’re just faster. The user profile is varied: from women concerned about losing strength during menopause to fashion professionals, such as Max Auth, a director of the Wolford brand who confesses to spending about $300 a month on these sessions to maintain his figure with a minimal investment of time. The reality bath Faced with marketing claims that “20 minutes are equivalent to 4 hours in the gym”, the scientific community has decided to take action on the matter. Cedric X. Bryant, executive director of the American Council on Exercise, points in WSJ that these claims are hyperbolic and that what one should expect from these workouts is being greatly exaggerated, while acknowledging that they may offer mild to moderate improvements. To shed light on the matter, various studies have analyzed the real impact of WB-EMS on different population groups: In older and sedentary adults: A research published in Clinical Interventions in Aging demonstrated the effectiveness of this technology in sedentary and thin older women, at risk of sarcopenia (loss of muscle mass) and abdominal obesity. After subjecting a group of 23 women to 18 minutes of WB-EMS (three sessions every 14 days) for 12 months, the results showed significant and positive differences in appendicular muscle mass and a reduction in abdominal fat mass compared to the control group. The study concluded that, given the good acceptance of the technology, WB-EMS is a valid and less daunting alternative for subjects who do not want or cannot do conventional exercise. In recreational athletes: Another essay published in Frontiers in Physiology analyzed the effects of WB-EMS in male recreational runners. For 6 weeks, participants reduced their running training to a single day per week and added a weekly WB-EMS session. The results indicated that the electrostimulation group improved their maximum oxygen consumption (VO2max), their ventilatory thresholds, their running economy and their vertical jump. This suggests that WB-EMS may be an effective stimulus to maintain and even improve performance in periods where resistance training volume is reduced. The definitive comparison (The WB-EMS is not a miracle): To check whether electrostimulation is really superior to classic sweating, the FIT-AGEING project evaluated 89 sedentary middle-aged adults. A rigorous study also published in Frontiers in Physiology divided the subjects into three 12-week programs: traditional concurrent training (recommended by WHO), high intensity interval training (HIIT), and HIIT added to WB-EMS. Finally, all types of exercise induced similar increases in cardiorespiratory fitness and muscle strength. In fact, the scientists explicitly concluded that the changes observed in the WB-EMS group were not superior to those of the other conventional exercise programs. The suit does not provide any extra decisive advantage compared to sweating the shirt in a traditional way. The silent danger of overexertion Despite the obvious benefits, WB-EMS is not a toy and carries risks if not properly supervised. As he … Read more

DeepSeek promised them happiness as the great Chinese AI. I didn’t count on a small detail: Kimi

April 7, 2026 by usatoday24

Just a year ago, DeepSeek was one of the biggest scares that Silicon Valley had received dwarves. A Chinese model trained with a fraction of OpenAI’s budget equal to GPT-4 in benchmarks. Upon its arrival the message seemed clear: Western dominance of AI had its days numbered. Today, the story stands, but not thanks to DeepSeek. The DeepSeek case. DeepSeek carries months late for its V4 and, to date, has already lost three of the authors of R1, the model that catapulted them to success. The monthly downloads fell 72% in the second quarter of the year, seeing how Doubao (ByteDanec) snatched the lead. With missed dates, usage errors due to cyber attacksand the difficulty of split from NVIDIA To bet almost entirely on Huawei’s Ascend chips, Chinese alternatives like Kimi have been gaining ground. Meanwhile, on the other side of China. Moonshot AI was not born surrounded by noise like DeepSeek. It was founded in March 2023 by three former colleagues from Tsinghua University: Yang Zhilin—PhD from Carnegie Mellon, former Google Brain and Meta AI—, along with Zhou Xinyu and Wu Yuxin. There were no visible or media faces behind it, only product. That product is Kimi, and in early January 2026 the company launched it in its K2.5 version. In code and video benchmarks managed to surpass GPT-5 and Gemini Pro 3with the key to Chinese AI: its API costs between 4 and 17 times less than OpenAI’s. Those responsible for Moonshot explained how Kimi was almost at Claude’s level in software development testing, encouraging the race for open models. The money arrived. The commercial results are what really attract attention. In less than 20 days Following the launch of K2.5, Kimi’s cumulative revenue exceeded everything billed during 2025. API’s international revenue increased fourfold since November of the previous year. The consequence in valuation has been dizzying: 4.3 billion dollars in December 2025, 10 billion in February 2026, 18 billion in March. Three months, valuation multiplied by four. Kimi has thus become the fastest decacorn in Chinese business history. The Chinese maelstrom. DeepSeek was born a year ago as the great revolution that questioned the closed model of Silicon Valley. It only took a few months for Moonshot to steal the limelight and manage to be on par with – or even above – giants like Google and OpenAI in the most used models in the world. In favor of DeepSeek, it should be noted that its objective is different: it does not follow the typical startup pattern with pressure for immediate monetization and it is a gigantic AI laboratory that can afford not to win in the short term.

Larry Ellison promised them very happy with his new luxury yacht named after a Japanese goddess. Made a rookie mistake

March 28, 2026 by usatoday24

In the world of technology, there are more or less discreet billionaires and then there is Larry Ellison. He millionaire founder of Oracle has made ostentation his watchword: has a private island (where he wanted to feed the world with a sophisticated 500 million dollar irrigation system), a long list of properties distributed throughout the United States and other countries such as Japan, an exclusive private jetand is also investing in the search for eternal youth. Of course, he also has boats: he currently owns the Musashi, which is his fourth superyacht. Love for ships and Japan. Ellison’s love for the sea dates back to at least the 90s, at which time he even became a sponsor of the BMW Oracle Racingwinner of the 2003 America’s Cup. His current superyacht is 88 meters long, cost him about 160 million dollars in 2011 and its name is clearly of Japanese origin. In fact, it is a tribute to one of the most famous samurai. Its interior also shows Japanese influences. In addition to the Musashi, in its history of boats with Japanese names there is the Sayonara sailboat, with which won several world championships racing, or the 75-meter superyacht Katana. But his first motor superyacht was the Ronin and it cost him some headaches. Ronin It means lordless samurai, but that was not his original name. It was conceived as Izanami. The impressive Izanami. In the late 90s Ellison set his sights on a superb second-hand superyacht called Izanami. Designed by none other than Norman Foster in the early 90s, built at the German Lurssen shipyard and commissioned by a mysterious Japanese businessman, it stands out for its defined geometric lines and its aluminum hull. It combines modernist architecture with great performance: at 59 meters in length, it was capable of reaching an impressive maximum speed of 34 knots. Inside, five cabins to accommodate up to 10 guests and 14 crew members in total. The mistake that no one saw coming. The name chosen by its original owner, Izanami, comes from Japanese Shinto mythology: the goddess of creation and death, consort of Izanagi. On paper, it fits like a glove: it is cultured, it is evocative… it fits for such a superb yacht. Larry Ellison paid 25 million dollars for it and was preparing to enjoy it when, docked in San Francisco Bay, in Sausalito, his name made a splash. If you read the name “Izanami” backwards you find a tasteless surprise: “I am a Nazi”, especially considering the German manufacturing and Ellison’s Jewish origins. Change of name and owner. The tycoon tells it in his authorized biography “Softwar: An Intimate Portrait of Larry Ellison and Oracle” from 2003: “When local newspapers started pointing out that Izanami was ‘I’m a Nazi’ spelled backwards, I had to choose between explaining Shintoism to reporters at the San Francisco Chronicle or renaming the ship.” He did the latter: Izanami became Ronin. Ellison enjoyed the Ronin until 2013, at which time He sold it to the Venezuelan banker Víctor Vargas and this one would later be sold to the Italian businessman Alessandro Del Bonothe CEO of the pharmaceutical company Mediolanum Farmaceutici. Today is for sale for 28.5 million euros. In Xataka | In 1988, Larry Ellison rented a Concorde and filled it with journalists just to say that Oracle 6 was going at supersonic speed.

OpenAI promised them they would be happy selling hype and memes. Until reality hits

March 25, 2026 by usatoday24

The news of the weekend is Sora’s closure. What was once the platform of the hype Regarding video creation, he says goodbye, leaving agreements behind millionaires with giants like DisneyOpenAI’s promise to be one of the big players in text to video, and doubts about the company’s strategy. The bet on hype. For some time now, OpenAI’s strategy has been to create hype, be the protagonist in the conversation, and wait for the user to assimilate its proposal. The problem? It is a strategy that worked in its initial phases, when OpenAI played practically alone. We saw it with Sora: the launch was the most talked about on networks, television and practically all media. Months after its launch, there was no way to use the app without VPN outside the United States (and in a very controlled way through its app in countries such as Canada, Japan, Korea or Vietnam) and was still in the experimental phase. The closure. Sora hasn’t lasted even two years. It was born in February 2024 and says goodbye in March 2026. What was born as the reference model for video creation remained a half-baked experiment, while Chinese giants or Google itself with their models I see They advanced and landed their models on the plane that really matters: the one that allows the average user to access it. The competition tightens. OpenAI promised them happiness two years ago, when ChatGPT had hardly any rivals and companies like Anthropic were in their early product stages. But photography has changed in just a few months: Claude is becoming, with almost daily iterations, the most complete chatbot (it is already much more than that). Gemini has been starting to eat his toast for a year. China is absolutely unleashed launching spectacular video models like Seedance 2.0. AI solutions are no longer promises and hype: they are rapid and controlled launches, integrated into platforms that any average user can access. If you don’t integrate, you don’t win. Seedance 2.0 has not even been running for three months and already It is beginning to be integrated into editing programs such as CapCut. AIs like KlingAI have been integrated into gigantic platforms like HighsfieldAI for months. Releases that materialize a few days after seeing the light, and that lay tangible foundations for the state of AI in text to video. OpenAI assumed that a minority of professionals would be willing to pay for the more expensive versions of GPT to access Sora. The reality: the competition is managing to create much superior mass-use tools, and OpenAI cannot afford tools like Sora. The money is on the other side. Sam Altman need to redefine the strategy. For the moment, he wants double the company’s workforcecenter everything in one superapp that reduces catalog and he has his eyes on Spud. This is the name given internally to the next great AI model they are preparing, one aimed at making OpenAI finally a profitable company. After years without a fixed direction, and with its rivals eating its toast, OpenAI faces its most complex stage: one in which selling hype is not enough.

2026 promised to be the great year for US tourism. Now it has found itself with a hole of 11 million visitors

February 28, 2026 by usatoday24

2026 looked good for US tourism. with the sector recovering of the pandemic on an international scale, the US started the year with three ‘hooks’ capable of attracting thousands of visitors: the world cup of FIFA, the centenary of Route 66 and the 250th anniversary of the Declaration of Independence. Three milestones that under normal conditions would make agencies, airlines and hotels rub their hands. Instead of that voices sound that warn that curves are coming. There are those who warn that the American industry risks losing a fortune and it is even done a question: Are there millions of tourists missing in the country? What has happened? That in a year in which (theoretically) the United States has everything in its favor to reinforce its tourism, in the country voices arise that speak of the complete opposite: loss of tourists foreigners and dark clouds on the horizon that threaten to cost the sector billions and billions of dollars. a few days ago The New York Times public an analysis in which he already slipped several worrying data: in January the flow of foreign travelers fell 4.8%a percentage that is largely explained by the decline in Canadian tourism, 28% lower to that of 2024. It is not only that the data is bad, it is that it maintains the negative trend of 2025, the year in which the US suffered a 6% decline in foreign visitors while the industry grew globally. How does 2026 look? That same question Oxford Economics did it not long ago, especially because according to its records in 2025, international overnight stays were reduced by 5.7% in the US. His answer is interesting: the observatory estimates that in 2026 the influx of foreigners will increase by 3.9%, although this growth is accompanied by some fine print. Getting started Oxford Economics remember that the celebration of the FIA World Cup, which the US hosts jointly with Mexico and Canada, should be enough to boost the arrival of tourists. However, the 3.9% forecast for the US is much lower than the increase in demand expected worldwide, which is around 8%. Its analysts already warn that the US risks “underperforming other international markets again this year.” Is there more data? Yeah. TNYT appointment some analyzes and sources that point to stagnation or even a drop in demand from Europe. The most revealing is a study by Cirium that reflects a year-on-year drop of 14.2% in July reservations made from the old continent. The data must be handled with caution in any case. First because 2026 has just begun. Second, because the analysis is based on external sources and travel agendas, which does not include reservations processed directly with airlines. Can the panorama change? Yes. A month ago World Travel & Tourism Council (WTTC) launched a resounding statement in which he warned of the impact they would have the new demands posed by Washington for travelers who want to use the Electronic System for Travel Authorization (ESTA), including a in depth review of the applicant’s history on social networks. If the measure is finally applied, the organization warns, the sector could suffer a drop in demand with serious consequences. “34% of respondents say they are less likely to visit the US in the next two or three years if the changes are implemented. Only 12% say they would be more likely, which will translate into a significant net decrease in travel intentions,” explains. WTTC estimates point to a loss of 4.7 million international arrivals and $15.7 billion in visitor spending. In terms of employment, some 157,000 positions would be damaged. Are there more factors at play? Yes. The changes to the ESTA would explain the losses calculated by the WTTC for the future, but they do not the ‘prick’ that foreign tourism in the US already suffered in 2025, a year in which the sector grew in most destinations. In fact, the UN itself has highlighted the “weak results” of the US, especially during the third and fourth quarters. What is the reason for this trend? For the WTTC the answer seems clear: in 2025, with Trump in the White House, I already warned that “while other countries welcome (the traveler) the US Government hangs the ‘closed’ sign.” How is the sector doing? It is not the only warning he issues. The WTTC recently recalled that the US inbound tourism market has suffered the loss of 11 million visitors in just four years, between 2019 and 2025. The organization does not go into details or delve into the data. The one who does it is the UN, although for the whole of North America. According to your statisticsIn 2019, the region received 146.6 million foreign visitors. In 2025 there were 135.4. That period has coincided with the pandemic and its subsequent hangover, but in recent months it has been marked by international politics led by Trump, with threats of one kind or another to the EU, Mexico and above all Canada and Greenlandterritories that the Republican wants to annex to the United States. Why is it a problem? “When eleven million international visitors fail to show up, the result is billions of dollars in economic losses for the travel industry,” warns in The New York Times Erik Hansen, director of the United States Travel Association. As the New York media recalls, the Trump administration has not made it easy for travelers, restricting entry from a dozen countries and announcing measures that would make visas more expensive and would force tourists to undergo deep scrutiny to enter the country. With that backdrop, there are those who already has called for a boycott trips to the US, even during the world cupamong other reasons for protest due to the actions of ICE.

Apple promised they would be happy by sweeping the iPhone in China. Until Huawei made things clear

January 15, 2026 by usatoday24

For years, the iPhone was the best-selling mobile phone in China despite the efforts of Asian manufacturers. Xiaomi, Huawei, OPPO and Vivo were fighting to create a product at their level (or even superior in some key aspects, such as the camera), achieving privileged positions in a ranking in which Apple used to dominate. It’s not like that anymore. Again, king. Huawei has been in first place in shipments within its country for more than two years. This past 2025, despite having lost 1.9% in annual growth, it is still slightly above the iPhone company. Specifically, 16.4% market share compared to Apple’s 16.2%. Apple grows 4% year-on-year, an increase motivated by the great commercial reception of the new family iPhone 17. In fact, Apple has already surpassed Samsung and has become the first manufacturer worldwide, despite being the second in China. Yes, but. Although Huawei is reigning with an iron fistthe data is not enough to assert that this will continue to be the case next 2026. There has never been such a fierce fight between the main Chinese manufacturers. Huawei: 16.4% market share. Apple: 16.2% market share. Vivo: 16.2% market share. Xiaomi: 15.4% market share. OPPO: 15.2% market share. Minimal differences in quota that will translate into a constant dance of positions during 2026. There is a clear message here: Huawei has not been able to be stopped in its native country. The Huawei case. Vivo, Xiaomi and OPPO maintain a close relationship with Qualcomm, the giant in charge of providing the best high-end Android devices with the most powerful chips on the market. Meanwhile, Huawei has had to adapt to playing with more restrictions than the rest: has had to develop together with SMIC their own processors He had to create a software ecosystem completely independent of Android Almost completely redesign your supply chain Make an even more ambitious bet on your domestic market, where life without Google is the norm The surprise. For years, we have seen Chinese mobile phones as great high-end proposals, but with some important disadvantages compared to Western rivals (fewer years of support, mediocre video recording, “crazy” specs without any sense of assembly…). This has been changing for a while now.. Today (saving the subjectivity of which software we like more or less), Chinese mobile phones are the most ambitious hardware proposal overall. They have the best batteries on the market, by far. On a photographic level, they are beginning to move dangerously far from Apple, Google and Samsung. The hardware set usually far exceeds what we see in the rest of its rivals. Chinese brands are very focused on their expansion throughout Europe, and it shows. not so fast. The Asian market is a great mirror in which to see how the fight between large technology companies progresses, but its particularities are still there. On a global level, at least currently, Apple and Samsung seem practically unreachable. Only Xiaomi, with a 13% share worldwide (compared to Apple’s 20% and Samsung’s 19%), plays in the double-digit league. Vivo and OPPO, with a share of 8%, have not moved their position since 2023. By 2026, consultancies like Counterpoint expect a year of moderation and a poor growth forecast. The global price crisis in DRAM/NAND memories will force an imminent price increase. Whoever manages to contain the dam will win this year. Image | Xataka In Xataka | Chinese mobile phones conquered the market by dividing into a thousand different brands.

Apple, Google and Samsung promised them happily with 5,000mAh batteries. Until China came to rub their hands on their faces

December 30, 2025 by usatoday24

The person writing these lines has an American mobile phone—made in China—with a little more 5,000mAh. A figure in which giants like Apple, Samsung or Google have been comfortably installed for years. Meanwhile, in China, Honor has just made official a phone with a 10,000 mAh battery. The launch is not surprising just because it has managed to literally introduce a powerbank inside a smartphone. It is surprising because it breaks a barrier that until now no one had dared to cross. Not due to lack of possibilities, but due to industrial inertia. The aforementioned. Honor has made the Honor Win and Honor Win RT. Two phones that, in addition to having the best Qualcomm processorshave a 10,000mAh battery made of silicon-carbon technology. The message is clear: this is not a typical high-end, it is proof that China is the leading benchmark in batteries for smartphones. thickness. For years there has been an unwritten but unquestionable rule: more battery means more thickness. The 10,000 mAh were reserved for rugged, bulky mobile phones designed for very specific uses. These Honor Win break that logic. They are thinner than a iPhone 17 Pro Maxbut with double the energy capacity. There are no gimmicks, fine print or marketing exercises: it’s a real leap in energy density. How did they achieve it?. Honor has not specified how they have managed to take the capacity to such an extreme but the person responsible is clear: silicon-carbon. This technology has been demonstrating for years that it is possible to introduce much denser batteries in the sizes in which lithium has already reached its ceiling. Chinese mobile phones have been standardizing for more than a year batteries over 7,000mAhand Honor’s move to reach five figures marks what aspires to be a new standard. The cons. Silicon-carbon poses certain challenges, and the first is degradation. These batteries, especially in their first generations, They seemed not to be at the same level as classic lithium batteries. Over time, the promised charge cycles are virtually identical to those of traditional lithium batteries (more than 1,500). The second is the cost: producing this type of cells is more expensivewhich partially explains why, for the moment, these figures reach China first and not global markets. In fact, a common practice is to find models whose Chinese version has more battery than the global version, reserved for the rest of the markets. A third key point is related to security and regulation. Denser batteries require stricter controls, and Western regulatory frameworks are not always prepared to adopt these types of advances so quickly. None of this invalidates progress. It simply explains why Apple, Samsung or Google have not yet made the leap. It’s not that they can’t: it’s that they haven’t wanted to take the risk… yet. China is going to force a move. The 10,000mAh batteries are, without much room for doubt, one of the biggest technological leaps in the world of smartphones after the arrival of AI. A figure that will allow us to normalize the three days of average use without going through the charger. The leap is so relevant that, whether they like it or not, “traditional” manufacturers will have to start making a move, as they had to start doing with fast charging systems. Samsung has already started implementing the 7,000mAh in phones like the Galaxy M51but its high-end is still at the 5,000mAh barrier. Google also moves in the 5,200mAh and Apple… is Apple. With a greater or lesser pace of implementation, these manufacturers are forced to keep pace with China in these advances. And that translates into admitting that we were wrong about lithium.

Telefónica promised great savings by 2030. Its ERE has been negotiated at 2,500 million euros and 4,525 layoffs

December 22, 2025 by usatoday24

Telefónica and the majority unions UGT, CCOO and Fetico-Sumados have signed the employment regulation file (ERE) that will affect the seven subsidiaries of the group. The minimum volume of departures is set at 4,525 employees, 14 less than initially planned after a last-minute reduction in the divisions of Telefónica Global Solutions, Telefónica Innovación Digital and Telefónica SA As highlighted by CCOO statementthe agreement is reached after almost a month of marathon negotiations, which began in November when the management communicated its intention to carry out the ERE for objective reasons that would affect 6,088 employees. Fewer layoffs than estimated He agreement reached establishes the minimum departure of some 4,525 employees, which represents a reduction of 25.6% compared to the 6,088 dismissals proposed at the beginning of the negotiations. However, this limit only responds at a minimum estimatethe company estimates that finally about 5,500 employees will take voluntary leave. In any case, it is a lower figure than that announced by the operator before the negotiations. The bulk of the adjustment corresponds to the companies covered by the Related Companies Agreement (CEV), with 3,765 minimum departures distributed as follows: 2,925 in Telefónica de España (almost 33% of a workforce of 8,892 people), 720 in Telefónica Móviles (20% of a total of 3,587 employees) and 120 in Telefónica Soluciones (11% of 1,118 workers). In the case of these companies covered by the Related Companies Agreement, the final number of dismissals is not fixed, but depends on the volume of voluntary adhesions, with a range that goes from 3,765 to 5,040 departures. The group’s global units total 585 layoffs. 109 layoffs in Telefónica Global Solutions (17% of the 638 employees), 182 in Digital Innovation (18.3% of 993 employees) and 294 in the TSA parent company (25.3% of 1,160 employees). Added to these figures are 175 departures from Movistar+, which represent 20.3% of its workforce of 860 people, a significant reduction compared to the 297 departures initially planned. Economic conditions and membership requirements Compensation contemplates different sections depending on the year of birth of the workers. Those born between 1969 and 1971 will receive 68% of the regulatory salary until the age of 63 and 38% thereafter, although in Movistar+ those born in 1971 are excluded. For the oldest For those born between 1965 and 1968, the percentages are 62% up to age 63 and 34% thereafter, while those born in 1964 or before will receive 52% of the salary up to age 63 and 35% thereafter. To voluntarily join with these conditions, 15 years of seniority in related subsidiaries and 13 years of seniority in global subsidiaries are required. In addition, the latter include voluntary bonuses of between 5,000 and 18,000 euros depending on seniority, doubling the amounts initially proposed. The departure process will be carried out in a staggered manner depending on the subsidiary. For related subsidiaries, the voluntary departure request period will begin on December 29 and end on January 26, while for global subsidiaries, it will extend from December 29 to January 29. In Movistar+, the voluntary deadline is postponed until January 7 and will be accepted until February 6. Spend to save Telefónica calculates that this ERE will have a cost of about 2,500 million euros before taxes. For Telefónica España and Movistar Plus+ the provision will be around 2.3 billion euros, while for the corporate units it will be approximately 200 million euros respectively. These staff cuts are part of the new Transform & Grow strategic plan of Telefónica for the period 2026-2030, which seeks to save costs up to 3,000 million euros annually in 2030. However, the company estimates annual savings close to 600 million euros from 2028, with a positive impact on cash generation as early as 2026. Simultaneously with the ERE, Telefónica has reached an agreement with the union centers to extend the collective agreements of the seven subsidiaries until 2030. The most significant advance is the commitment to increase salaries 1.5% each year while the agreement is in force, affecting both the related subsidiaries and the global units of Telefónica. Employees of the linked subsidiaries will receive an additional payment of 300 euros in October, of which 150 euros will be consolidated annually in the salary tables. The social benefits include the extension of the teleworking package up to 12 days, the extension of the 36 hour work week to global units, the improvement of bank guarantees for home purchases from 75,000 to 100,000 euros, aid of 3,000 euros for rent and the declaration of December 24 and 31 as non-working days.

AI promised to free senior employees from tedious work. In reality it is loading them with more tasks

December 17, 2025 by usatoday24

Imagine a young recent graduate in finance, eager to join a large consulting firm. He dreams of learning the trade from below. That inexorably involves preparing reports, researching markets, creating presentations, etc. But along comes AI and suddenly those routine tasks are automated. He produce more and faster, but all that torrent of documents lands on the desk of the person in charge of supervising him, a senior manager who is now passing hours checking errors that have been overlooked. This scenario is what reveals a study prepared by the consulting firm UpSlide and its conclusion leaves an unexpected twist: artificial intelligence not only removes the access ladder for new workers, but also burdens the most veteran workers. AI takes away opportunities for recent graduates. According to the data that they are being collected In different studies on the impact of AI on recent graduates, job offers for entry-level positions have been reduced between 11% and 20% in the last year. The reason: AI now takes over the basic administrative tasks that before these young people did. Furthermore, a elaborate study by researchers from the University of Navarra and IESE Business School, based on data from 138 million workers in the United States, reveals that in companies exposed to generative AI, average salaries fall by 4.5% compared to those not exposed. In the most affected, the salary drop reaches 7.7%, with the initial salaries of juniors decreasing by 6.3%, while those of seniors remain stable or increase slightly. Juniors produce more, seniors review more. The UpSlide report indicates that younger employees use the AI tools their companies have implemented to improve their efficiency in distribution (24%) and research (22%) tasks. On the other hand, the use of AI for senior profiles implies an increase in the review and quality control tasks of their work. According to the authors of the study, while juniors have stepped on the accelerator producing more content and documentation with AI, seniors have had no choice but to dedicate more time in their day to review all that new AI generated content. “Rather than reducing workload, AI is displacing: it places more pressure on senior professionals, who must now review, validate and correct a growing volume of AI-generated content. This bottleneck is especially critical in high-value operations, where the margins of error are minimal,” the study’s authors underline. AI overloads seniors. The data indicates that 41% of the seniors participating in the study dedicate more than 11 hours per week to reviews, such as checking errors in the figures of financial presentations or formats. 83% of them recognize greater pressure on seniors for quality reviews, and 82% see more risk of those errors finally reaching the client. “While the technology is very impressive, it just doesn’t beat the professional touch. That’s why we’re making sure to create review checkpoints with humans in the workflow,” said Joshua Stolarz, Managing Director at KPMG in the study. A model that makes the revision more expensive. Yes, as they point out the evidenceAI automates training tasks for junior profiles, concentrating review on seniors, one of the arguments used by the main CEOs of technology companies that the use of AI would allow the most senior profiles to free yourself from administrative tasks to focus on giving value to the products. By leaving them with the burden of reviewing AI-generated content, you actually bury them in more administrative work. If the trend pointed out by the study is consolidated, companies could opt for more veteran profiles in their hiring, which would reverse the dynamics of fire these employees when the cuts come. However, these more experienced profiles also they earn better salariesso many companies could rethink implementing AI if it means increasing your labor costs.
