very high battery drain on s21 after last update

[Tesohh]

Hello, I recently installed an update on my S21 and there's some crazy battery drain.

I literally used it for 2.5 hours and it's at 28% (i even charged it a bit)

If you want to see my app usage:

Maybe good to do a clear of the Partition Cache of the phone.
Do you use any third party themes, as these can use a lot of battery if it's not optimised for the software properly
At worst backup your data a do a factory reset
Personally I would try the clearing of the Partition Cache first

Yup my base s21s battery is terrible after the last update.  I went from getting around 7 to 9 hours sot over 24 hours of use to 2.5 hours sot with 28% left over 15 hours of usage today. I'm so mad. I also own the s22 and got great battery life until the last update on this today. I'm pretty fed up with samsung. I have the flex alpha 2 and had to send it in for battery issues and got it back with physical damage and still a bad battery
