A recent Samsung update is causing battery issues. After installing the new One UI 8 interface, owners of various Galaxy models report significantly reduced battery life.
Both smartphones and smartwatches are reportedly affected by the battery problem. The Galaxy S25 series and the Galaxy Watch 7 are frequently mentioned in this context.
Update Causes Frustration Instead of Joy
The update to Android 16 and One UI 8 was supposed to improve device performance and energy efficiency. Instead, many users find their batteries are now draining much faster. Reports are piling up in forums and on social media, while Samsung has yet to offer a clear solution.
According to the South Korean magazine “Chosun Biz,” users on Reddit report significant losses. One Galaxy S25 owner explains that his smartphone now lasts only about six hours instead of eight. The differences are even more pronounced with the Galaxy Watch 7—by evening, only 20 percent of the charge remains, compared to 70 to 80 percent previously.
Samsung’s Response Remains Vague
Samsung points to possible individual factors such as changed usage patterns, app updates, or new system settings. A concrete solution has not yet been presented.
The manufacturer is currently distributing the latest security patch and working on the next version of its software, One UI 8.5. Whether this will resolve the battery issues remains to be seen.
