Depleting the battery fastly when my Galaxy A51 was updated to UI 5.1 yesterday. How to fix this issue? Thanks.

My Samsung Keyboard is 5.6.10.40 and Android version is 13

All my apps in Galaxy Store are the latest. I followed many Web instructions to do trials, allof them make no sense .

Any body knows how to fix it ? Highly appreciated. More Importantly: Samsung should not keep silent.

And the upper back of the phone is overheated than it was normal ever before ...

Hello IGoPublic, if you updated yesterday the phone is still learning your usage patterns.

Is normal in the period of time that the phone will drain the battery faster, it won't overheat.
