Samsung Galaxy S25 users report battery life issues after update

Users of Samsung Galaxy S24 and S25 devices have reported significant decreases in battery life following the One UI 9 update, which is based on Android 17.

Some owners claim their devices are lasting as little as five hours under normal usage conditions, potentially requiring multiple charges per day. While the issue appears most prevalent among those receiving the latest update, reports indicate that not all devices are affected by the decline in performance.
