Leaks of the upcoming Pixel Watch 4 have surfaced, suggesting that Google is once again prioritizing battery life in its next-generation smartwatch. Renders published by 91mobiles, courtesy of leaker OnLeaks, show a slightly thicker watch with two small buttons on either side of the speaker, whose purpose remains unknown. The Watch 4 is reportedly 14.3mm thick, compared to its predecessor's 12.3mm profile.

The increased thickness could be attributed to a larger battery or additional components, which would align with Google's focus on improving battery life in previous Pixel Watch iterations. The original Pixel Watch, released in 2022, was criticized for its dismal battery life, prompting Google to address the issue in subsequent models. The Pixel Watch 2 and 3 saw significant improvements, but still trail behind rival smartwatches like the OnePlus Watch 3, Samsung Galaxy Watch Ultra, and Apple Watch Ultra 2 in terms of multiday battery life.

The lack of charging pins on the Watch 4's sensor array is another notable feature. The pins, introduced with the Pixel Watch 2, enabled faster charging but were met with criticism from some users. Their removal could indicate that Google has found an alternative solution for faster charging, potentially using a different charging method or technology.

According to 91mobiles, the Pixel Watch 4 will still be available in two sizes, a welcome feature for users with varying wrist sizes. While the leaks provide valuable insights into the Watch 4's design, they do not reveal information about the device's internal components or the focus of WearOS 6, which is expected to be unveiled at Google I/O next month.

Industry experts believe that Google's continued emphasis on battery life is a strategic move to compete with other smartwatch manufacturers. With WearOS 4 and 5 already focusing on power efficiency, the Pixel Watch 4's improved battery life could be a key selling point for users seeking a reliable smartwatch experience.

While the leaks provide a glimpse into the Pixel Watch 4's design, it's essential to note that the final product may differ from these renders. Google has not officially confirmed the Watch 4's specifications or release date, leaving fans and enthusiasts eagerly awaiting more information at Google I/O.

In the meantime, the smartwatch market continues to evolve, with manufacturers like Samsung, OnePlus, and Apple pushing the boundaries of battery life, design, and functionality. As Google prepares to unveil its next-generation smartwatch, the tech giant will need to balance its focus on battery life with the demands of a rapidly changing market.
