Running on Android 15, Samsung’s One UI 7 version boasts a new interface along with several new capabilities. One of the unanticipated issues that many customers have seen with the One UI 7 is shorter battery life.
Even with minimal use, Samsung customers report that their Galaxy phones are having trouble lasting a full day. This article examines the sources of the battery life issues that were noticed following the One UI 7 update, as well as solutions.
Owners of Samsung devices have frequently complained about severe battery drain on websites such as Reddit, X/Twitter, and Samsung Community Forums.
One user of a Galaxy S24 Ultra, for example, reported that the screen-on time of their phone decreased to roughly 5 hours from 6–7 hours before to the update.
Another owner of a Galaxy Z Fold 6 claimed that by the end of the day, their battery had dropped from 45 to 50 percent to 20 to 25 percent.

Some users of the Galaxy S23 series have claimed similar issues, requiring two or even three daily charges for simple tasks like browsing or viewing movies.

As the device becomes used to the new software, the post-update optimization period typically lasts a few days to a week, but the problem seems to last longer.
Users have also reported related issues, like slower app loading times or phones that run warmer than normal, which could be a factor in the higher power usage.
While Samsung has not officially confirmed the cause, several factors could explain the battery drain. Since One UI 7 is a major software update, its new features, animations, and background processes may have been demanding more power.
User-installed third-party apps may not have been fully optimized with the new OS, causing battery drain. Another possibility is that background processes, such as system optimizations or data syncing, are running more frequently than needed.

If you’re experiencing battery drain after updating to One UI 7, here are some practical steps to try:
Clear the cache:
Enable Light Performance Profile:
Turn off AOD:
Update Apps:
Factory Reset (last resort):
You’re not alone if the One UI 7 upgrade has caused your Galaxy device’s battery life to suffer. You can handle the problem while you wait for a possible solution by attempting the aforementioned procedures and keeping an eye on Samsung’s reaction.
