It’s been just over a month since Samsung rolled out One UI 7, and early excitement over the redesigned interface and expanded AI features has given way to mixed reactions—especially when it comes to battery drain. While some users report longer SOT and smoother performance, a significant number of Galaxy owners say their handsets are now draining power faster than ever.On Samsung’s official forum alone, threads about post‑update battery issues have racked up over 50,000 views and hundreds of comments. Users of flagship devices—particularly the Galaxy S24, S23, and Z Fold 6—describe noticeably faster power depletion, with some even experiencing device warmth during light use. Similar reports have surfaced on Reddit and XDA, suggesting this isn’t an isolated glitch.
How to Fix Accelerated Battery Drain
1.Clear the Device Cache Partition
Boot into recovery and wipe the cache partition to remove leftover data from the previous version.
2.Enable Power Saving Mode
Turn on Medium or Maximum power saving in Settings → Battery to throttle background activity.
3.Use Galaxy App Booster
Open Galaxy Labs and activate App Booster (and keep all your apps updated via the Galaxy Store).
4.Factory Reset (with Backup)
As a last resort, back up photos and contacts, then reset your device to flush out any corrupt settings.
What to Do If Issues Persist
Patience is key. Major UI upgrades often need up to two weeks of background optimizations before performance—and battery efficiency—stabilize. In the meantime:
-
Send Feedback
Report your experience through the Samsung Members so engineers can identify and patch any lingering bugs. -
Maintain Battery Health
Try to keep your charge level between 20% and 80%, avoid extreme temperatures, and consider carrying a portable power bank to keep you going through the day.
With a bit of troubleshooting and time for One UI 7’s under‑the‑hood processes to settle, most users should see their battery life return—or even improve—over the coming weeks. Stay tuned for upcoming software fixes, and let us know in the comments how your device is holding up!
