Samsung One UI 9 update blamed for battery drain on Galaxy S24 and S25
Some Galaxy S24 and S25 users report much shorter battery life after installing Samsung's One UI 9 update. The Android 17-based software has prompted complaints following the upgrade.
The report centers on owners of Samsung’s Galaxy S24 and S25 handsets who say their devices last noticeably less time between charges after the One UI 9 installation. The software is built on Android 17, and complaints have followed the upgrade.
Because the available material is limited, the episode fits a familiar pattern in consumer technology: major software releases can produce unintended effects for some users, and reports often emerge after broad distribution. No further details about affected units, severity, or fixes are provided.
The impact may be most immediate for Galaxy S24 and S25 owners who rely on their phones through the day, as shorter runtime could disrupt work, travel, and communication. It could also shape how consumers view update reliability and how quickly they install future software, though the available reports do not establish how widespread the issue is.
