A surge of online reports indicates that some users are experiencing a recent increase in battery drain on their Pixel Watch, by as much as 20% every few hours.

Sometimes new software introduces extra stress on device batteries. New processes can take a toll on phone or smartwatch energy at a higher cost than expected, and that might be what’s happening with some Pixel Watch users.

It’s nowhere near a definitive trend, but it’s intriguing to see several new posts on Reddit pop up with the same complaint – their Pixel Watch’s battery is draining faster than normal (via Android Authority). One post has 65 comments, with a healthy number sharing the same concern. One user wrote that their Pixel Watch 2 is getting 12 hours of use on a full charge, instead of the normal 48 hours with AOD off.

The other user claims their Pixel Watch 4 now lasts less than a day. Their normal usage reportedly gets them up to 2.5 days. That’s high for the Pixel Watch 4, but it’s not unheard of. Both of these users dropping by 12 or 24 hours from one charge isn’t nothing.

Sporadic comments echo the same situation, but many report they haven’t noticed a difference. Timing isn’t entirely consistent across comments, either. Some say they started seeing the issue a few days ago, while others say this happened to them a while back.

Still, it might indicate a recent software update is to blame. Google’s recent September 2026 update reaches the Pixel Watch 2 and newer.
