It’s not just you: Galaxy S24 and S25 owners report excess battery drain after One UI 9
One user witnessed a 95% dip in battery after only 3 hours and 15 minutes of screen time.
A noticeable decline in battery life has been reported by users of Samsung's Galaxy S24 and S25 models following the rollout of the One UI 9 update. Multiple Galaxy S25 owners have also expressed similar concerns after Samsung pushed the Android 17-based update. The update, which introduced features such as Call Brief and My FanCam, has been gradually delivered to the Galaxy S25 and Galaxy S24 series.
A Galaxy S24 Ultra user shared their experience on X, noting a steep drop in battery life, lasting just 3 hours and 15 minutes with 95% battery consumption, even with extensive social media use and mobile data usage throughout. Samsung attempted to rectify the issue by reaching out to this user for a service appointment at a nearby store. The update, while adding new features, has seemingly impacted the battery life of these devices.
