Battery

[KateyMac96]

Does anyone else have a battery issue now with it draining faster?

[Z-52]

Yeah, same I have a s21 Ultra and it is draining way faster than usual for this type of phone. My phone gets hot after 10-20 minutes of use as well.

Clear cache of the phone on recovery mode

Excellent battery life on the S21 standard here

Great battery life on my s21+

Yes

I had the same issue on my S21 Ultra, wiped the cache in safe mode twice in a row, and now battery life is great.

Wiped cache once already on S21, didn't help battery issues. May try wiping again, but makes no sense it would take two tries... Cache wiped is cache wiped.

Same issue. Draining faster and taking longer to charge, plus running warm.
Seems better after cache wipe in safe mode.
