What is true of this model and changes how you fix it
- What has changed sinceSamsung's forum replies treat the first two weeks after a major update as a battery learning phase, so judge the drain after that.
- Safe mode isolates the causeRestart in Safe mode for a day. If the standby drain disappears, an app is behind it; if it stays, it is the update's learning phase or the battery.
- Power saving did not helpOne A25 owner saw the drain continue even in power saving mode, which points at the system rather than an app.

Questions that only have an answer for the Samsung Galaxy A25 5G
How much standby drain is too much on a Galaxy A25?+
A few percent overnight is normal. 5 to 6 percent an hour in standby, as one owner reported after One UI 7, is not; wipe the cache partition and reset battery stats first.
Should power saving mode fix A25 battery drain?+
It should reduce it. If the drain continues at several percent an hour in power saving, as one owner reported after One UI 7, the cause is deeper than the setting.
