Hi everyone,

​Since updating my Galaxy A55 to Android 16 (One UI 8.0), I’ve noticed a significant drop in battery life. Before the update, I could easily get through a 2 day, but now I’m hitting 20% before 24 hrs of charging with the same usage.

​Details:

  • ​Model: SM-A556E/DS
  • UpdateVersion: A556EXXSCCZA1/
A556EODMCCYL3 / A556EXXSCCZA1
  • ​Steps Taken: I have already tried [restarting/clearing app cache/etc.].
​Is anyone else seeing "System UI" or "Google Play Services" draining more than usual? Any tips would be appreciated!
