Note: these are users from other markets where S23 update was released, not Canada.

Samsung’s One UI 7 rollout, based on Android 15, hit the Galaxy S23 series recently, but some users are reporting higher battery drain, sparking chatter on Reddit and Samsung forums.

Samsung’s One UI 7, packed with a revamped UI and Galaxy AI features like Audio Eraser, initially faced a buggy rollout, paused briefly before resuming. Now, Galaxy S23, S23+, and S23 Ultra owners are voicing concerns about battery life post-update. A Reddit user with an S23 griped about charging “multiple times a day” for light Reddit and YouTube use.

Battery Life has gone down the drain on the S25 Ultra since the last OTA.. I wouldn't be in a hurry to get One UI V7.0, unless Samsung has fixed the battery issue.. I used to easily get 6+ hours of SOT..now I don't even get 4 hours of SOT! 

Always on Display was using a LOT, but I have since turned it off.. and still battery lasts about half as long as it did when I got my S25 Ultra! 

AOD & System UI are the two biggest problems!
