In the last week or so my S20 FE 5G battery drains very fast. The phone is constantly warm and when I charge it (several times a day) it takes much longer to fully charge - whether by regular or Fast Charging adapter.

This started suddenly, without any change in use or installation of new apps. I have tried many tips to consume less battery (background apps, dimming display, etc.) but to no noticeable change.

The only event that may be related to the onset of the issues is a One UI 5.1 system update on Feb 14, 2024.

Any similar issues around this time? Any advice?

Thanks!
