A number of Pixel Watch users have reported a sudden and significant decrease in their device's battery life. Online forums, particularly Reddit, show complaints of battery draining by as much as 20% every few hours. Some users claim their Pixel Watch 2 now lasts only 12 hours instead of 48 hours, while another Pixel Watch 4 user reported less than a day of use from a typical 2.5-day charge.
The timing of these reports suggests a possible connection to recent software updates. The September 2026 update for Pixel Watch 2 and newer models introduced "Gemini Personalization." Another possibility is the recent Google Health update, which includes automatic activity tracking. However, the Google Health update would not explain issues on the Pixel Watch 2.
While multiple users have raised concerns, the issue is not universal, with many reporting no change in their device's battery performance. Google has not yet officially acknowledged these battery drain reports or provided any explanation for the observed issues.
