Samsung One UI 7 Update Creates Battery Concerns for Galaxy S and Z Series Users
Samsung’s One UI 7, based on Android 15, was officially launched in January alongside the Galaxy S25 series. The update was later rolled out to older models such as the Galaxy S24 and Galaxy S23 series. However, a growing number of users are now complaining about severe battery drain issues after installing the update.
Battery Life Drops After One UI 7 Update
Multiple users across platforms like Reddit, X (formerly Twitter), and Samsung’s support forums have reported a noticeable drop in battery performance. Devices from the Galaxy S series and Galaxy Z foldable series appear to be most affected. One Galaxy Z Fold 6 user mentioned that their battery level now drops to just 20–25% by the end of the day, compared to 45–50% before the update. Similarly, a Galaxy S24 Ultra user claimed they are now getting less than six hours of screen-on time, a significant downgrade in battery efficiency.
Complaints Extend to New Galaxy S25 Series
Surprisingly, the battery drain issue is not limited to older models. Some users with the latest Galaxy S25 series are also experiencing similar problems after installing the One UI 7 update. While Samsung has not yet issued an official statement, the company may release a battery optimization fix with the May 2025 security update.
Temporary Solutions and User Advice
Until an official fix is released, some users have shared tips that may help reduce the battery drain. Common suggestions include:
-
Clearing app cache via recovery mode
-
Allowing a few days for One UI 7 to optimize in the background
-
Performing a factory reset if the issue continues
It’s important to note that after any major Android update, smartphones often use more battery temporarily due to system reindexing and background app optimization. However, if performance doesn’t improve within a few days, manual troubleshooting might be necessary.
One UI 7 Update Rollout Timeline
Samsung began rolling out the One UI 7 update to older Galaxy smartphones and tablets on April 7, 2025, after launching it with the Galaxy S25 lineup earlier in January. The update brought several new features and design enhancements, but the unexpected battery drain issue has raised concerns among long-time Samsung users.
