With Scanwatch 2 updates with a 35 -day battery life, Apple Watch could only dream of

With the best known for its smart scales and similar devices, also manufactures a series of Smartwatch, the last of which is the Scanwatch 2. In IFA 2025, the company has announced a new blue and silver version of the 42 mm model. He also unveiled HealthSense 4, an AI software update that operates technology to manage a set of new health and sleep monitoring features.

I took a photo of the scanwatch 2 while I was there, and now I receive the attraction of this watch. If you are not familiar, the big scanwatch problem is that they are like intelligent watches disguised as old regular analog watches, with mechanical time of time and a more standard global face. The screen itself is only a complication of the watch watch – a small circle integrated into the upper part of the screen. The scanwatch 2 is beautiful and the silver model with blue bands is no different. In fact, I am a fan of blue, if only because he reminds me of the blue costume that Adam Sandler wears throughout the film Drunk Punch. (If you haven’t seen it and make fun of an Adam Sandler mention in this very serious article, cut it and go watch the film.)

This version of Scanwatch 2 is now available on the Withings, Amazon, Target and Best Buy website, and costs $ 369.95. Buyers will have a month of Withings more for free. (After that, it’s $ 9.95 per month, or $ 99.50 per year.)

Under the hood, the scanwatch 2 does a lot of what other smart watches do more remarkable. It takes action measures such as heart rate and blood oxygen level, or performs ECG readings to supply detection of atrial fibrillation.

With HealthSense 4, the Scanwatch 2 (and Scanwatch Nova and Nova Brilliant, but not the original light scanwatch or scanwatch) can now follow the REM sleep and take more precise measurements of your respiratory rate while you sleep. Withings says that its new algorithms, using data collected by smartwatch, such as variability of heart rate, physical activity, body temperature and respiratory rate – can find possible causes of fatigue, and provide recommendations fueled by AI by telling users what they could be able to feel less tired all the time. These recommendations are collected under what Withings calls the Vitality indicator, which you need a Withings plus subscription to access on your phone.

With the product manager, Etienne Tregaro has traveled to me some of the new features of the application at IFA 2025. The Vitality Indicator screen gives you an overview of your “vitality”, which I considered a kind of shortcut for printing by the IA system of Withings of your overall preparation to cope with a given day. The days of the week at the top of the screen are filled with green contours circles which can be anywhere not existing at a full ring – the more the ring is full, the less tired. Below, various boxes tell you where you are for the day in categories such as recovery and effort.

The Withings application also offers within Intelligence – A chatbot you can talk about about your health measures. He can take note of the models; Another representative of Withings with whom I spoke showed me a screen where the chatbot noted that he had just lost a little weight, speculated on the causes and asked him if he had intentionally tried to lose weight. In theory, that would give him useful advice, according to his answer.

The subscription also gives access to notifications fueled by AI allowing users to know when their menstrual cycle begins or when Scanwatch 2 has picked up signs of an infection. The Withings Plus service is also delivered with cardio control, an option for your cardiovascular data to be checked by a professional cardiologist, which returns a basic summary of what they have seen and recommendations to deal with the problems that may have occurred.

It is an amazing update that jumps on the more passive presentation of the information on Apple’s health and more closely reflects companies like Samsung to deploy AI, informed by Smart Wearable data, as a health coach. I fear that this can lead to some people more in unhealthy obsessions with the constant monitoring and microgestion of their health? I am not an expert in this; For this, I encourage you to read the many articles on the subject. We drive in a new border with a generative AI now becoming more deeply tangled in intelligent portable devices, and only time will tell us.

One thing you will not need a subscription is improving the battery life that comes with the new HealthSense4 software. Now, the scanwatch 2 obtains 35 days on a charge, which is up compared to 30 days before, already much more battery life than most standard smart watches. Although to get there, you will probably have to deactivate a number of scanwatch 1 features, such as its display always or its blood oxygen sensor.

Tregaro told me that Withings had managed to add these days by identifying the areas he could optimize his code. I asked what your settings should look like reach 35 days on a load, because obviously, you cannot expect that while using each feature that Scanwatch 2 offers. He said you should deactivate a number of features, including part of the monitoring or night notifications. With, to his credit, has a graph which can tell you what features lead the largest penalty of battery life. Delighted to have a guide.
