I’ve had my S24 Ultra for about 4.5 months, and ever since the One UI 7 update, battery life has gone downhill fast. Before the update, I’d get about 1 to 1.5 hours of screen-on time per 10%. Now, it’s under 40 minutes per 10%, even with light usage like Brawl Stars, TikTok, and Snapchat. I also experience noticeable idle drain—a few percent per hour.
I reported this to Samsung, but the response was clearly recycled from a previous ticket—referring to old log files from months ago when the issue wasn’t this bad. I’ve done everything right: Adaptive Battery on, AOD set to Tap to Show, and I leave apps in Recents (no force closing). I even did a factory reset after the update, but battery life and performance still haven't improved.
On top of that, there are new glitches:
1. In landscape mode, pulling down the notification panel stutters and lags, especially during games.
2. In the Phone app, default background images don't apply anymore. Only video call backgrounds work. If I select a default image, it just shows the contact's profile color instead.
Samsung Support told me to wait a week post-update—but it’s been weeks, and nothing has improved.
