TL;DR
- Some Galaxy S24 users are reportedly facing a significant dip in battery life after the recent One UI 9 update.
- Multiple Galaxy S25 owners are also reporting similar problems after Samsung’s Android 17-based update.
- Samsung recently started rolling out the One UI 9 update to the Galaxy S25 and Galaxy S24 series, introducing features like Call Brief and My FanCam.
After a brief wait, Samsung began rolling out the One UI 9 update to the Galaxy S25 series, followed shortly by the Galaxy S24 lineup. While the update adds features like Call Brief and My FanCam, it may also be hurting battery life.
A report from a Galaxy S24 Ultra owner on X shows battery life declining 95% with only 3 hours and 15 minutes of screen-on time (via SammyFans). This is a steep drop, even with heavy social media use and being on mobile data the entire time. Samsung later contacted this user to schedule a service appointment at a nearby store.
