Google prepares to launch the Pixel Watch 4, and despite expectations of major new features, the latest leaked data points to a continued strategy in the processor department. The company's next smartwatch is shaping up to be an evolution of its predecessor, where the The most notable changes will be in the battery and user experience., rather than pure performance.

According to various sources close to the company and reports from specialized media, Google has opted to keep the Snapdragon W5 Gen 1 processor in the next generation of its smartwatch. This chip has been on the market for several years, but it remains the benchmark in the sector for manufacturers other than Samsung, as Qualcomm has yet to release a truly innovative alternative for wearables.

Battery news: more capacity and improved autonomy

One of the major areas for improvement will undoubtedly be autonomy. Pixel Watch 4 batteries will be larger than those of the previous series. The 41mm model increases its capacity to 327 mAh (7% more), while the 45mm one will go up to 459 mAh (9% more than the previous generation). Although the increases are not disruptive, will allow the clock to offer a few extra hours operating, something highly requested by users of previous versions, who criticized the limited battery life, especially with the screen always on.

Although Qualcomm is already working on a new generation, Google has reportedly decided not to wait and to once again bet on this chip, waiting for its own Tensor processor to arrive on these devices in future generations. This leap is expected to occur in the next edition, but for now users will have to settle for the current configuration, which, while efficient, is starting to get worse. fall somewhat short of more advanced proposals.

Improvements to the display, sensors, and customization options

In addition to the battery, leaks suggest that the Pixel Watch 4 will come with a brighter screen, which could reach 3.000 nits of peak brightness, improving visibility outdoors and in bright ambient light conditions.

Among the most technical advances, the inclusion of an auxiliary coprocessor, moving from the Cortex-M33 to the new M55, which, according to leaks, will allow you to manage much more demanding artificial intelligence workloads, especially with the integration of Gemini and advanced Wear OS features. This move not only aims to optimize performance, but also to offer a smoother and more new features in terms of smart functions.

The sensors section will also receive an update: Heart rate, SpO2, ECG, compass, altimeter, gyroscope, barometer, and UWB connectivity, among others, will be maintained and improved.All of this, coupled with a wider variety of straps (including sport, two-tone leather, and metallic options) and a wider selection of case colors, makes the Pixel Watch 4's customization a key draw for those looking for a custom device.
