The battery quality in mobiles

by

I have interviewed enough brand leaders to have something very clear: the battery is one of the characteristics that most influences the purchase of a smartphone. In Europe we seemed doomed to a very specific figure: about 5,000mAh that remained immutable generation after generation. Chinese mobiles have begun to mark a trend with 6,000mahbreaking it in specific cases such as the Redmagic 10 Pro with its 7,000mah or the recent one Honor Power, with 8,000mah. In addition to the clear war in relation to the milliamps-Hora this eagerness for Chinese manufacturers to bring the best batteries goes further: the focus is in their quality and usability. Crazy about capacity. Broken the 6,000th barrier, we published a piece that has not taken long to materialize: one regarding that this roof surpassed, We don’t know where the limit is. Honor has already managed to introduce 8,000mah On a phone with an 8mm thickness, the same of any other traditional smartphone. Realme rises to 10,000mahabsolute madness. From one year to another, the 5,000mAh of the competition have become an obsolete figure, although everything that shines is not gold. A change in industry. That this capacity has been unlocked has a main responsible: the Silicon-Carbon batteries. Here manufacturers have been pioneers by introducing this technology, which allows you to introduce much more energy capacity in the same size. From a time to this part, this type of batteries has become more and more popular, although some manufacturers (including the Chinese) They reserve them for China for a simple reason: costs. Beyond silicon. Longevity is another obsessions for this 2025, and OnePlus is the best example. His OnePlus 13t It is able to function without using battery, but electric current, when plugged in the current. This function, which we already saw in the past in Redmagic mobiles (and Sony already flirted with it in some Xperia), is ideal to preserve the life of the battery on the scenario that suffers the most: when it is connected to the current making discharge cycles. A perfect ally. A good part of the responsibility in these advances has it Catlone of the giants in the battery industry (mainly in the industrial and electric car spheres). In recent years, Catl has collaborated with manufacturers such as Realme for the joint development of batteries, betting on silicon-carbon as material. A dart to the rest of the manufacturers. The 6,000 (or more) MAH are becoming a standard, and now the glove will have to pick it up the rest of manufacturers outside China. Betting on this type of batteries is not cheap, but launching a terminal with a 5,000mAh battery will begin to become a competitive disadvantage for the rest.

And suddenly, a great battery and the Sun of Murcia saved me from the great blackout

by

After a crisis, a couple of disturbing war conflicts, Trump’s second mandate And a worldwide pandemic, The biggest blackout in Spain I shouldn’t have caused me so much concern. But at home, at three o’clock at the beginning and with the children newcomers of the school, his nervousness was very evident. And ours. No electricity grid for almost 12 hours And disconnected from the world almost the same hours except for the blessed radio to batteries, at home the tranquility for the tense and indefinite wait came to us in the most unexpected way: the radiant sun of Murcia and some test batteries in Xataka. This is the story of how some Solar panels connected to a large battery The great blackout of Spain mitigated at home. The reality that everything works with electricity The entrance/exit door of the work center, which we usually opened through an application installed on the mobile, only paid attention to our need to exit urgently when the concierge, analog key in hand, opened it and threw from it under the almost 30 degrees of two in the afternoon in Murcia. At the end of April. “Googlear” if the suppliers of the service stations need food to work, something that would have taken me 10 seconds at another time, was the beginning of many hours of energy uncertainty whose solution did not remember that I had at home On the way by car home, with the deposit near the reserve and without knowing for sure if the suppliers need food to function – or possibility of Googlear the answer to my doubt – the radio was the only point of connection with the real situation. Because the theories about what was happening did not take 10 seconds to run from Boca by ear and another ear … Suddenly, everyone had spoken with a family member abroad who confirmed without any doubt that it was a European issue. What European, world. An “makeshift” installation of solar panels on the home terrace With the few news that I could hear about what was happening I got home. The atmosphere was very similar to that of pandemic, with uncertainty dominating everything. And the feeling of living too many things for the first time. The noon food had to improvise according to very clear criteria: use the perishable of a refrigerator that we did not know when it would be operational and resort to gas barbecue. Yes, the induction cuisine does not get along with the lack of electricity. Already with the serenity that gives the stomach well attended, as a game to calm the kids, we analyze the situation at home and draw a plan for the afternoon. We are looking for lanterns, laptops, “powerbanks” and any device that could be charged. The smartphones and tablets between them. To do so we had an immense, literally, allied at home: some ecoflow batteries tested in Xataka. Time to recharge everything rechargeable. And cook the “cooking” With the internal load of the batteries, a main of 4,000 mAh and an assistant of the same capacity, almost 80%, the four plugs and four USB ports (two of type C and two of type a) they began to recharge everything that we found at home. Including the batteries that we already know that they must be in every emergency kit that boasts. Without the possibility of loading of any kind, the solar batteries of the house offered a recharge point to family and friends who requested it The objective was that, if the situation was extended until night, we could have operational devices And of course Lights ready so that, at least at home, the situation was the most similar normality. Batteries, camping and reading/leisure lights for the long wait Since it was still the beginning of the afternoon in Murcia, the batteries continued to recharge to the usual rhythm in their “rush hour”, about 1,000-1.200 W per hour. One of the great advantages of these Ecoflow batteries for recharge is that they can be feed both from the electricity and connected directly to solar panels. The radio we were about to “recycle” last summer We take advantage of this situation of energy surplus for both less important issues and relax with a fresh coffee and to use certain thermomix type appliances, the microwave or a small electric oven. Everything we could take advantage of that solar energy seemed to us a good idea at that time. Things of situations that are first lived. Mobile of friends and family who lived near them were recharged with our house battery We also rejoice at home of having stored an old analog radio because, without data or functional telephone, it was our only source of reliable information. The great blackout was not this time through streets. No neighborhoods. Not even in cities. But the most alarming was that the duration of it was a great unknown. So the very few moments of connectivity allowed us Offer our batteries to family and friends They lived close to recharge their mobile phones. And without sun, the batteries take control of the house With the different official information about everything that happened arriving via radio but on droppers, the sunset reached us at home with the unknown about what would take the electricity grid of our Murcia area to be operational. So without a sun, it was time to start squeezing the Energy stored throughout the day until it exhausts her. At night, the solar battery was ready to use the stored energy and feed the refrigerator for hours and thereby save food for a very valuable time The system that we have ecoflow proof does not allow energy injection to the home network itself if it is not connected to the general. But his poOutput tenance of up to 4000 W gives us the possibility to use powerful appliances in a timely manner, as we did with the water tank or microwave. At night, in … Read more

How to load your mobile battery when there is no electricity

by

Let’s tell you How to load your mobile battery when you don’t have electricityeither by some blackout in your area or for some other situation. Because in these cases it is normal for us to throw a lot of mobile, and that it is the device that we need most to have loaded. The mobile has become the environment with which we communicate, we inform ourselves and entertain ourselves, so it is important to keep it with drums. That is why we are going to give you some tips that will help you keep it loaded. Load your mobile without electricity Let’s give you a series of Methods to load the mobile without electricity at home In list format, with descriptions of why each of the methods we recommend. Of course, there should be Prepared for any light of light In some cases. These are the methods you can use: Use an external battery: If you have an external battery at home, you have a treasure in these cases. It is the main method you can use. If the battery has a good capacity of about 10,000 mAh, you should have several loads of your mobile. Plant it with your laptop’s battery: If you have a laptop at home that still has a battery and you will not use it, you can connect your mobile and use the laptop as an external battery. Of course, this will exhaust the computer battery very quickly, that is, be careful if you are going to need it. The battery of your car: You can also go to your car and connect it to one of the loaders you have. In these cases, it is important that you keep the car started, and to be able to circulate with it, so that the battery is not exhausted and you can start it later. Solar or crank batteries: There are other types of batteries or loaders that you can use, such as those that use the sun to load (although in a very slow way), or those that have a dynamo or crank to generate electricity. They are little efficient methods, but they are. Try not to use the mobile much: Finally, we are going to advise you that in these cases try not to use the mobile too much, especially not use demanding games or apps that drain the battery. Use the energy savings mode you have and reduce the brightness of the screen, also turning off Bluetooth, GPS or Wifi to maximize the battery life you have.

We lead all my life by measuring battery capacity in mobiles. Mah’s war makes no sense

by

How many more mah, better. We have been thinking about the specifications of a phone and, to a large extent, is something true. A greater capacity battery is usually a more capable battery with respect to a smaller. Despite this, there is a somewhat more complex unit of measure, but even more precise, traditionally used in the technical sheet of computers: Los watts-Hora (WHE). This is the most precise way to determine how long we can use our device, without leaving the capacity to your fate. We are going to explain, without delving too much into technicalities so as not to complicate your life, why we have been imprecisely measuring the battery capacity of our mobiles. Why do we measure in mah. The commercial standard for the phones battery is the Miliamperio Hora, a very useful measure for small devices with constant voltages. In addition, it is much more striking to indicate closed figures, such as 5,000mAh, than to tell that your mobile has a 19.4 Wh. However, its two main problems are, in the first place, when there is a voltage variation (you will soon understand why) this measure ceases to make sense. Although MAH is easy to understand, it does not provide an exact estimate of available energy, which can lead to incorrectly assume how long the battery will last in specific situations of use. Water measurement time. The watts -hora (WH) are the most precise unit to measure battery capacity, since they reflect the amount of energy available depending on voltage and current. He watt (w) It is the power unit, which indicates how much energy is consumed per unit of time. It is more useful to know how the battery will be used during the daily use of your mobile. The battery voltage is not constant: it is varying as its percentage of load and useful life changes. A battery, At the end of your useful lifeIt does not provide the same voltage as when it is new. In fact, if you have a modern car or motorcycle, you surely have access to real time voltage and you will see how you change as you use the vehicle. The mobile battery is lowercase compared to these, but also suffers small voltage variations. The ease of calculation. Even if the voltage was constant, the watts time would be an ideal measure. For example, if your mobile phone had a 5,000mAh battery and a typical voltage (the most common in phones) of about 3.85V, that battery would translate into 19.25 WH (capacity (MAH X Voltage / 1,000). Knowing the data, it would be enough to know the consumption in watts to deduce almost exactly how much the battery would last. In a concrete situation, as a very demanding game that leads to consume 6W constantly the division would be easy: 19.25 wh/6W = 3.2h. A data that stables: about three hours of screen with the mobile spending all rag This is why in segments such as computers, where consumption is crucial and marketing (something) less important, WHH is established as a standard to measure battery capacity.

Makes external battery for mobile

by

There are manufacturers who try to differentiate themselves from original ideas and it is very much appreciated. HMD, the Finnish company that Until recently Nokia’s phoneswe were surprised during this Mobile World Congress with a device as simple as it is striking. And useful. Because in the end that is what we all look for. May technology help us. Next to Fusion X1 have presented the new HMD Amped Buds. Wireless headphones with noise cancellation. They offer high resolution audio, 95 hours of playback and have 10mm controllers. But it is none of these characteristics that make it unique in the market. The first with reversible wireless load. The HMD Amped Buds are the first headphones whose load base also serves to load the mobile. To date, the case served to load the headphones themselves, but HMD has concluded that that battery can be used for something else. Compatible with any mobile with wireless load. And what better than loading the mobile. Although stylized, the HMD Amped Buds case has reverse wireless load, to be able to load any mobile that admits wireless load. The case is very light. It has a weight of 78 grams, a thickness of 14.3mm and a height of 74mm. To get an idea, it is somewhat less than half of a standard mobile. And the case of magnetically hooks on the back cover of the mobile. We simply approach and voila, we already have an external emergency battery. Perfect for an emergency. Let’s not think that we will have an external battery with a great capacity. It is simply to load the headphones (up to 11 times) or to load the mobile at a timely moment. Its capacity is 1,600 mAh. The battery also has a USB-C port, in case we simply want to load the cable mobile. Headphones manufacturers, take note. After having been able to try these headphones, whose price is 199.99 euros, I must say that they seem to me to follow closely. I have not had the opportunity to check its sound quality, but to try its ultrafine load case and test the wireless load with a pixel and an iPhone. The result has works as one expects. To the first. In my case I usually use the JBL Tour Pro 3 And they seem to me a very curious option for their external screen. But in fact it does not seem to me a sufficient justification to have that large load case. If all manufacturers take note of this idea of ​​case with reversible wireless load, we will win. Since we have to have a battery for our headphones, what less that also serves us for the mobile. In Xataka | Someone has created headphones that do not need adapter to charge.

A battery to feed robots from the heat of the human body

by

Of all the submundos on the Internet, my favorite is that of youtubers who dedicate months to an engineering project of doubtful profitability for the simple fact of trying. The Matrix. There is a whole generation of adults that in 1999 saw ‘Matrix’ in the cinema. The Matrix, the concept of engineering from which the science fiction film of the Wachowski sisters starts, is a machine that uses humans as batteries to extract from their body the energy that feeds the robots. With the AI ​​advancing at runaway, it does not seem like a project that we want to materialize precisely now. But would it work? To verify it, someone is needed with the motivation and the determination of carrying out a project or too useful, or too profitable. Exact: You need a youtuber. Basically Homeless’s human battery. This is the name of the Nicka Zetta channel, the youtuber and inventor that concerns us. Inspired by matrix, Zetta designed a special suit that takes advantage of the heat generated by the human body to produce electricity. The premise is simple: the side of the suit that is in contact with the skin is heated when the person is active, because his body generates heat, while the other side, exposed to the cold air of the environment, remains fresh. That temperature difference can be used to produce electricity. How it works. To convert the temperature difference into electricity, it is enough to use a thermoelectric generator, a device with two conductive materials, one on the hot side and one on the cold side, which generate a potential difference (that is, an electrical voltage) to take advantage of The Seebeck effect: electrons move from the hot to cold, creating a current flow (that is, electricity). The problem is that the human body does not generate too much heat, nor does it at a specific point, so many thermoelectric generators were needed to achieve a non -despicable amount of energy. The limitations. During the suit tests, Nick managed to generate electricity peaks that soon down because the temperature difference with the outer side of the suit was matched. To avoid this problem, he devised a way of producing “heat pulses”: great temperature differences in short periods that allowed him to obtain more electricity. The body is heated when exercising, but also (not trying at home) when drinking alcohol or ingesting spicy meals with a lot of capsaicin. If at the same time the outer air is cold, the temperature difference is important. Feeding a robot with the suit. Although the invention failed to generate enough energy to load a mobile, it did produce electricity in small quantities that were enough to move a small robot on a table. Maybe it is not the matrix that science fiction fans imagined, but remember that the film’s robots could not obtain electricity from the sun with photovoltaic cells, which would be much more efficient, because humans had darkened the sky in an attempt to end the energy of the robots.

2025 will be full of unforgettable readings. Right now, this is what is in Xataka’s slope battery

by

Let us recognize it: we love Christmas because if we like reading, dozens of books rain. The drama arrives in January, when the battery acquires proportions of skyscrapers. In Xataka we have already got to work and we are engaged in multiple readings. Perhaps some of them are interested in increasing your own list of outstanding volumes. This is what we are reading! ‘Cointeligency: Live and work with AI’, by Ethan Mollick I am still reading Mollick’s book and it is one of those rare readings about ia that manage to keep their feet on the ground. The one of the books of AI is a section full of tectoutopic manifestos or apocalyptic warnings, but this text, at least in what I have read, stands out for its genuine curiosity and healthy skepticism. Who reads it will find a pragmatic analysis of how to integrate these tools into our life, without falling into the trap of imagining that they can or should do everything, and of course without falling into cheap catastrophism. Mollick understands that the real question is not whether we will use the AI, but how we will choose to use it. Javier Lacort Cointeligencia: Living and working with AI (connects) * Some price may have changed from the last review ‘Everything dies’ by Juan Gómez Jurado I am reading with some laziness the eighth book of the Red Reina saga, more for a “since I have read the previous ones, to know how this ends”, although I am seeing myself coming than last delivery, nothing. The familiarity of knowing both the characters, the humor of the dialogues and the narratives, and the tone of action so characteristic of Gómez Jurado are liking, but I cannot avoid that feeling of reading again the same and with the same resources that work from the first books. Fear gives me the end. At least, for now he is being entertaining and agile. César Muela Everything dies (everything burns 3) (Red Reina Universe) * Some price may have changed from the last review ‘The newspapers of La Boticaria’, by Natsu Hyûga I had been listening to this series for a long time, and how good it is, but since I did not usually trust the Hype I took late to read the manga. It was a serious mistake. ‘The newspapers of the apothecary’ tells the story of Mao Mao, a herbalist who was kidnapped to work as a maid in the imperial palace. I must admit that at the beginning, it is hard to believe that she is the protagonist of the series. It appears to be a dry girl whose purpose is to avoid getting into trouble in life. The only thing that seems to care is his father, a doctor named Luomen, and the only thing that excites him is the poisons. Although Mao Mao promised to maintain a low profile in the palace, he cannot avoid taking action on the matter when the children of the emperor mysteriously begin to get sick. His actions put him in the spotlight of Jinshi, a beautiful eunuch that is responsible for managing all the affairs The Interior Palace. As opposite as water and oil, together they are dedicated to investigating the mysterious cases that are crossed along the way. You will not be able to avoid laughing when you see this pair, as well as its numerous misunderstandings, in action. In addition, the manga is impressive and reflects the talent of the artist, Nekokurage. ‘The newspapers of the apothecary’ is available in numerous formats. Apart from having its own anime in Crunchyroll, it is also available in Japanese light novel format, which is where it was born. After seeing the anime, I have read the manga and read the light novels because, as you can see, my head went a bit. However, I can only say that it is a will to how good this series is and how it leaves you asking for more. Jody Serrano The newspapers of the apothecary no. 01 * Some price may have changed from the last review ‘Travel with Herodoto’, by Rysard Kapuściński I have always liked to read. From childhood. But it took me much more to launch me for readings that can carry the label of “journalistic”, if we understand from chronicles to essays written by and for reporters. The first, I remember it well, was a book of Manu Leguineche about the vericuetos of this profession. I devoured it when I was in the second year of Baccalaureate, while I was enrolled in Communication Sciences. The second, if the memory does not falter me, was ‘the cynics do not work for this trade’, the classic classic of Rysard Kapuściński for aspiring stories. From those years of university I recognize that I had abandoned the Polish, the cheerful face, with a sharp look and populated eyebrows, that the students of my fifth contemplate with devotion when I went up to collect the Prince of Asturias. In the Faculty I also read ‘ebony’ and ‘One more day with life’, but I had one of his great works pending, which, if I am not wrong, puts the brooch to his bibliographic legacy and in a way it serves as a vital testament , professional and deontological: ‘Travel with Herodoto’. 2025 has started fulfilling that pending account. It has been my first reading. And how I appreciate it. ‘Travel with Herodoto’ is chronic, biography, communication treaty, sociological essay and a declaration of love towards reading and history, a philosophical manifesto and the daddy test that mixing the local and global approach is not only possible, it is also necessary. It is all that and something else: the frank and uncomplexed work of an extraordinary reporter who does not tremble the narrative when moving from his own childhood memories to the political column or the fragments of a chronicler who lived more than twenty centuries before him . ‘Travel with Herodotus’ is also something else: … Read more

The Poco F7 Pro and F7 Ultra will have a smaller battery

by

In the coming weeks, Xiaomi will globally launch the Poco F7 Pro and F7 Ultrawhich will be a renamed version of the Redmi K80 and K80 Pro (respectively) that the company previously announced in China. Everything indicates that these models will arrive with practically the same characteristics, except for one important difference that considerably harms the models that will debut outside the Asian market. As revealed Xiaomi Timea portal specialized in news and news from the brand, the Poco F7 Pro and F7 Ultra They will have a lower capacity battery compared to the Redmi K80 and K80 Pro. The Redmi K80, which would arrive in Europe under the name Poco F7 Pro, was launched in China with a battery of 6550mAhas well as a 90W fast charge. The global version, on the other hand, would have a battery of 6000mAh; also with a 120W fast charge. In any case, and although we lose 550 mAh, the battery capacity that will arrive with the Pro model will be more than enough even for the most demanding users. Where we will see an important difference is in the Poco F7 Ultra. The Redmi K80 Pro has a 6000 mAh batterywhile the version that will be announced in the global market could arrive with only 5300 mAh. In both cases, yes, with a 120W fast charge. Why the Poco F7 Pro and F7 Ultra will have less battery At the moment, Xiaomi has not justified this decrease in battery capacity, and the reasons are only assumptions. One of the reasons would be the reduction of production costs, which in turn would allow the models to be launched on the global market at a lower cost. It would not be strange if Xiaomi has also decided to limit the battery capacity for regulatory reasons in the European Union, or simply for safety. In any case, the Poco F7 Pro and F7 ultra They will arrive with very interesting specifications, including a processor Snapdragon 8 Elitea triple camera of up to 50 megapixels and a screen with 2K resolution. Of course, both the Poco F7 Pro and the Poco F7 Ultra will arrive with HyperOS 2.0the latest version of Xiaomi’s operating system, and they will do so under Android 15. Its price, however, remains unknown.
