a month later, the answers are not so obvious

Time passes so quickly that it’s hard to believe that the new iPhones have been in stores for more than a month. The truth is that Apple has made a move again, and it has done so with a model that renews materials and promises a more balanced experience. But after three very continuous generations, the question is once again the same: has anything really changed? in a new 24/7 from the Xataka YouTube channel We have tested it for 30 days to see if these changes are noticeable on a daily basis or if history repeats itself. For 30 days, Ana Boria has coexisted with the iPhone 17 Pro Max in all types of situations: recording, working, playing or taking photos outdoors. Their goal has been to see if the change in materials and the new design translate into a different experience or if, in the end, day-to-day life feels the same as before. On Xataka’s YouTube channel We already put the Freestyle Libre 2 glaucometer to the test for a week, and we also dedicated a month to the Xiaomi 15 Ultra now to the Smart Band 10. This 24/7 It follows that same approach of prolonged use to understand the product beyond the technical sheet. iPhone 17 Pro Max: a month of in-depth testing The change of materials is appreciated from the first moment. He iPhone 17 Pro Max It leaves titanium behind to adopt an aluminum chassis with more curved edges and a more pleasant touch finish. Apple justifies this step as a thermal improvement, and in tests a more uniform distribution of heat has been noted when the phone is working at its limit. The flip side is that aluminumsofter, shows marks easily, although for Ana the sensation of use compensates for that loss of hardness: “in that sense it seems to me that the change in design is much more successful and comfortable.” After a week of use, our colleague focused her attention on the screen and sound, two sections that this year arrive with small adjustments. The panel now reaches a maximum brightness of 3000 nits, improves contrast and adds a new anti-reflective coating. In practice, it ensures that the experience does not change too much: outdoors it looks perfect, but not better than before. So we wonder if the new anti-glare really makes a difference outside the laboratory. The new A19 Pro is responsible for making everything work very smoothly. Ana acknowledges that the jump in power is not as noticeable as one would expect: “In practice I cannot tell you that this increase in performance is noticeable.“What does change is the heat management. Thanks to the aluminum body and the vapor chamber, the heat is distributed evenly and localized overheating disappears. The result is a more stable phone, which withstands intense sessions without losing fluidity or reducing brightness. The iPhone 17 Pro Max cameras maintain the level, but the new 4x telephoto lens steals all the attention. Its more practical distance is valued, although it is admitted that the behavior is not always predictable: “it is that at no time do you know with what lens the photograph is being taken.” On the positive side, the 18 MP selfie allows for effortless reframing and the stabilizer “was good before, but now it’s a blast.” Is this really the step forward we were hoping for in mobile photography? After a month of testing, Ana sums it up with a phrase that makes the dilemma clear: “We have the best iPhone Pro that has ever existed, pero doesn’t reinvent the wheel“The interesting thing is in everything behind that conclusion: the nuances, the surprises and the comparisons that can only be understood by seeing it in action. All that, and the final verdict, They are in the video on Xataka’s YouTube channel.

We will respond to your doubts about the Rowenta X-Force Flexa flexible portable vacuum cleaner perfect for leaving all corners very clean. We have been testing it for several days, and now we bring you a video with all the answers to the questions that you have been sending us about it at our Instagram profile. Rowenta X-Force Flex Q&A We begin our review of all the doubts about the vacuum cleaner by talking about the power it has This Rowenta. Its maximum power is 240 Air Watts, which is what will be activated when you use Boost mode. Come on, it’s not the normal power, but the one it gives you when you press the turbo. Another question has to do with their suction levels, because there are several. First you have an ECO mode which serves to consume less energy and emit less noise, and with which in our tests we have been able to vacuum most of our house without too many problems. Then you have Max modewhich gives you extra power for especially complicated surfaces, such as carpets. And finally you have the Boost mode, which is the most powerful, and is used for that dirt that remains more embedded and is more difficult to vacuum. The vacuum has a start and use trigger, and another red one that takes you directly to Boost mode to make it easier to use and more accessible. But you also have an automatic mode It uses normal mode, but when it detects more demanding soil, it increases the power. You have also asked us about the noise it makes when vacuuming. ECO mode is usually around 70 dB, which is very little annoying. The Max mode goes up about 10 or 15 dB and everything starts to sound like a conventional vacuum cleaner, and the Boost mode almost reaches 100 dB, but it is the one we are going to use the least. In the video, we also show you vacuum cleaner accessoriessuch as its flexible broom or its different brushes that adapt to your needs. You also have another accessory for crevices and another for the sofa, as well as a motorized brush for pets. We then go into depth about the flexible broom to show you how it works.

what it is and how to use it to get AI answers with a list of sources

Let’s explain to you What is it and how to use Google AI modewhich you can use both from the search engine’s website and from the mobile application. It is a new method that uses Gemini to find information in the search engine, and offer it to you in a more detailed way. We are going to start the article by explaining what exactly this AI mode is, so that you understand how it works and what differentiates it from normal searches on Google. And then, we will give you a simple explanation on how you can use it. 10 GOOGLE APPS THAT COULD HAVE SUCCESSFUL What is Google AI mode When you use Google normally, you are offered two types of results: first you may have a summary of the results made with artificial intelligenceand then below you have the links. AI mode use Gemini to maximize mode View created with AI of traditional searches. It’s similar to doing a search in Gemini, but the difference is that the main sources used appear on the right side. Come on, the result is generated from these sources, and you can review them whenever you want. So that you understand it. When you search for something in Gemini, practically no sources or links related to the information appear, and when you search for something in Google the summary made by AI is quite insufficient. So, AI mode merges both concepts so that you are offered results showing the sources in a prominent way. Unlike the View created with AI From conventional results, which generates the summary of related sources using literal quotes, this AI mode generates the summary independently by Gemini. It takes into account the sources and their information, but it is as if the AI ​​generated the answers on its own. From top to bottom: Google results, Google AI Mode results, Gemini results. This mode works with a version created specifically for searching Google’s Gemini 2.0 model. This means that in addition to finding the results, you will also be able to have conversations with exhaustive questions. Come on, after asking the question, you will be able to ask questions, and you will also be able to ask longer questions for more detailed answers. How to use Google AI mode The first thing you have to do is enter the Google website or application. Once inside, press the button AI Mode which will appear to the right of the search bar on the web, and below it in the mobile application. This will take you to AI mode, where you can ask any question or consult anything you want to know. You can also ask the question by dictating it by voice, and you will have the option of adding images to ask questions about its content. You will see how Google processes the question and consults several dozen pages, and then will generate a complete and detailed response. The most important thing in this way is that On the right you will have the entire list of sources. This is important because AI can make mistakes due to hallucinations or using unreliable sources, but this mode will allow you to consult the sources so that you can verify the information on pages that you know will offer it to you in full.

Experience leaves difficult answers to ignore

He Free Freestyle 2 It is designed for those who need to control their glucose daily. But what if someone proves it In medical terms you do not need it? On this new 24/7 of the Xataka YouTube channel We have used it for more than a week to understand what it contains to live with that level of continuous control … even when there is no diagnosis behind. Mario Arroyo He has used it for more than seven days in a row, in all kinds of situations: from a copious meal to a paddle game or a night with unexpected dances. “O oysters! Eh, nothing hurts, nothing hurts.” The reaction was spontaneous and marked the tone of a test that did not intend to issue medical trials, but observe how such a device behaves outside the usual context. Freestyle Libre 2, Live with a 24 -hour glucose sensor The first thing that impresses with free freestyle 2 is its appearance. When opening the package and seeing the applicator, our partner’s reaction was clear: “God, what a piece of needle”But that feeling vanished to put it on. The process is fast, without pain. For a full week, it has even unnoticed when sleeping, exercising or showering. What seemed invasive, turned out to be comfortable. The sport also left its mark. After playing the paddle for two hours, the glucose level collapsed: from a normal value to only 57 mg/dl. Something similar happened at night, where several declines were detected without apparent cause. Three hypotheses were afloat: the soft diet for being sick, possible imprecise readings of the sensor or, ultimately, a body notice. At that point, the tool ceases to be just a curiosity. To what extent can we trust your alerts? Synchronizing the sensor with the mobile is as simple as approaching it for a few seconds. The app is updated every minute, showing the current value and its evolution with arrows. In addition, keep the record and allows you to consult the maximum and minimum daily. It is a tool designed for those who need to monitor their glucose, but its clarity makes any user interpret it. Does that constant information provide if you don’t depend on it. After eating a “normal” dish of about 70 grams of turkey rice, the glucose reached its highest peak of the day: 168 mg/dl. The fact, although within the expected, caught the attention for how fast it went up and how much it varied against the previous value. Measure before, just after and after two hours it allowed to visualize how the body responds. With the sensor, what was previously invisible is now drawn in real time. The sensor has an error margin of approximately 9.2%, according to the company that manufactures it. A reasonable fact for a system that does not require medical intervention. But the cost is another story. There are cheaper optionsand its price can be a real barrier. The question, then, is not only if it works, but for who works. Is it a useful tool for anyone or only for very specific profiles? After more than seven days with the sensor, the experience has been positive, although nuanced. He adds: “It seems to me a very comfortable device” and acknowledges: “I think that if you do not have a real problem of diabetes, its usefulness is somewhat limited.” Technology works, and works well. The complete analysis, with all the details, is in the last video of our YouTube channel. Images | Xataka In Xataka | I have used Ultrahuman glucometer for two weeks without being diabetic.

These glasses with AI have been designed to look like a genius. They register your environment and give you all the answers

by

Imagine carrying glasses that seem normal, but that inside offer you constant and silent help. The concept sounds intriguing: without touching anything, You can solve doubts instantlyreceive a clear explanation of something that you do not understand or have an automatic translation in the middle of a talk. A startup called Halofounded by former Harvard students, has created glasses with that idea in mind. And not only that: they promise to endow us with a “superhuman intelligence.” Beyond the marketing strategy, the approach is interesting. Glasses that listen and respond in real time Halo X do not resort to cameras to dazzle us, but bet on a different approach. They are designed for Listen to what happens around youtranscribe each conversation and show on an internal screen information that they consider relevant at that time. They do not wait for them to dislike, but try to anticipate and be useful proactively. In practice, that means that if the name of a car model arises in a talk, they can show a card with key data; If a technical term appears, promise to display a clear definition. The information operation appears in front of your eyes in less than a second. Even in everyday situations, such as speaking in another language, they should be able to real time and facilitate communication without having to do anything else. Halo talks about answers around 900 milliseconds for most consultations, while the most complex searches take about two and a half seconds. To achieve this, the glasses rely on two complementary artificial intelligence engines. Geminithe Google model, is responsible for reasoning tasks, while Perplexity It works as a contextual search engine that consults information on the web. As for the hardware, the halo X bets on the discretion. Incorporate a small type display Waveguide Visible only for the user, microphone and integrated speakers, and dispense with this version. The autonomy announced is around eight hours of continuous use. Of course, they do not process everything on their own. They depend on a connected mobile phone and an application that acts as an intermediary, where most of the calculation and consultation work really runs. The great debate point is in privacy. The system records what you listen, transcribes it and, according to the company, eliminates the audio immediately after. Halo ensures that the product will arrive with end -to -end encryption and that is working to obtain the SOC 2 certification, which would imply external audits on data management. The system records what you listen, transcribes it and, according to the company, eliminates the audio immediately after. However, they do not include any visible indicator that alerts those around you that they are being recorded, and that raises reasonable doubts. The controversy is not new: the founders They had already experienced with unauthorized facial recognition systems about Meta Ray-Banwhich generated debate about security and improper uses of technology. At the moment, Halo X are not available in stores. They can be reserved on the official website with a starting price of 249 dollars And, by selecting euros in checkout, today they appear in 223.13 euros. The company has not yet offered a specific date of shipping or confirms whether there will be official distribution in Europe. It will be necessary to see if the halo X does not end up repeating the recent history of other devices that promised to revolutionize our relationship with artificial intelligence and ended up being sued fiascos. Rabbit R1 and the AI ​​Pin of Humane They aroused enthusiasm in their presentations and arrived with very ambitious speeches, but failed in practice. Halo’s ambition is on the table and his proposal is as attractive as controversial. It remains to be seen if these glasses They fulfill what they promise or if they will end up swelling the list of inventions that pointed high and stayed on the road.

Grok 4 destroys the tests and aims to be the most advanced AI model. The problem is that Elon Musk continues to sabotage his answers

by

Xai has launched Grok 4its new artificial intelligence model that is sweeping the most demanding performance tests in the sector. The model exceeds OpenAi, Google and Anthropic proposals in multiple benchmarks. And is that in the absence of knowing OpenAI’s strategy with GPT-5At the moment it has all the ballots of being the most pointer the model. However, Grok continues to drag the usual problems: controversial responses, offensive content and an Elon Musk using the model to subtract credibility. The numbers speak alone. In the test Humanity’s last examconsidered one of the most difficult to measure abilities of AI, XAI states that Grok 4 has achieved 25.4% Without additional tools, surpassing O3 of Openai (21%) and Gemini 2.5 Pro from Google (21.6%). But it is with Grok 4 Heavy, its multiagente version, where the results shoot: according to the company, reaches 44.4% With ‘tools’, almost doubleing competition. Image: XAI In addition, at the benchmark ARC-AGI-2which measures the ability to solve complex visual patterns, Grok 4 has obtained 16.2%practically double the next commercial model. According to Musk“Grok 4 exceeds the doctoral level in all subjects, without exception”, an affirmation that, although it sounds to marketing, is supported by the results obtained. The revolutionary approach. Grok 4 Heavy works with A “multiple agents” system that work in parallel about the same problem, then comparing their results as if it were a study group. This architecture allows you to climb intelligence according to the available computational power, a concept that could redefine how we understand the AI ​​performance. Image: XAI The usual problems. The launch of Grok 4 occurs just after the previous version of the chatbot published anti -Semitic comments In X, even identifying as “Mechahitler” in some answers. XAI had to temporarily withdraw the service and eliminate offensive publications, while countries like Poland They announced complaints before the European Commission and Türkiye blocked access to chatbot. The cause was a modification in the system instructions that allowed the model “not to avoid politically incorrect statements.” Although Xai withdrew that guideline, the damage was already done. A constant sabotage. Despite these technical advances, Musk continues to condition Grok’s responses in ways that compromise their usefulness. The model performs automatic searches for the opinions of the tycoon in X to respond to controversial issues, turning the alleged search for “truth” into an echo of its creator’s ideas. This practice, confirmed By experts in AI like Carlos Santana, he once again demonstrates how Musk’s controversial decisions are directly influencing the development of the model. In addition, several researchers already They have managed to avoid Easily model safety barriers, making it generate content on chemical weapons, malicious software, drugs and other sensitive issues through relatively simple jailbreak techniques. Ethan Mollick, professor at Warton and an expert at AI, Point out The lack of transparency of the company: ‘There is no detailed technical documentation, risk analysis or explanations on how to avoid future incidents’. This opacity makes it difficult for companies to trust Grok for critical applications. Grok 4 prices. XAI Grok 4 Basic offers at a price of about 30 dollars a month. However, the company has also launched Supergrok Heavy, a subscription of $ 300 per month in which its most advanced model is offered and that directly becomes the most expensive market service on the market. What is coming. XAI plans to launch a programming model in August, multimodal agents in September and video generation in October. Also will integrate Grok 4 in Tesla vehicles Next week, expanding the scope of AI throughout the Musk ecosystem. The question is whether the company will separate the technical excellence of the media controversies that surround it, or if it will remain hostage of its founder’s impulsive decisions.
