A growing number of Samsung Galaxy S25 Ultra and Galaxy S24 Ultra users are reporting significant battery drain issues following the installation of a recent system update. Disgruntled owners across online forums, Reddit, and Samsung’s official community boards state that their flagship devices are experiencing rapid power consumption, even during standby, along with noticeable thermal throttling and unexpected heating during basic tasks. Several users have reported screen-on time dropping by up to 30% to 40% compared to performance prior to the patch, forcing many to recharge their phones multiple times a day. While background system services such as One UI home processes and location tracking have been identified as potential culprits, manual troubleshooting steps—including clearing cache partitions, resetting network settings, and running app optimizations—have yielded mixed results for affected owners. Samsung support representatives have acknowledged the feedback and advised users to submit error logs through the Samsung Members app, but the company has not yet issued an official statement or released a hotfix update. Tech analysts speculate that the battery drain may stem from an unoptimized background sync bug in the patch, which is expected to be addressed in an upcoming security release.
