Ever since I updated to android 12 UI 4, my battery seems to drain faster.  Anyone else with a similar problem?

Hi Daikos, Please go to the Samsung Members app which is already pre-installed on your Samsung device >> Get Help >> Diagnostics >> Battery. Please write back to us with the results.

It's fairly typical to see a change in battery life / usage / measurement after an Android version update.

Give it a few days to settle in & possibly have to let the battery "relearn" your usage.

I'm not sure what Samsung has built-in to the Firmware update process, but it's quite likely that the battery usage history was wiped with the update.

If you haven't already, you could Boot into recovery & wipe cache at the very least, but I always backup my phone with smart switch & factory reset.

There's supposed to be a script built-in to the updates that clears cache, but sometimes it needs a little help.

But I've always Factory Reset after any Android version update, & never had any issues. 

 

One final thought, it's also possible that the One UI V4.0 update itself has some usage / performance issues, which would likely be corrected in the next update.

Cool. Thanks for the tip. I'll try it although I hate reinstalling every single app

Backing up with Smart Switch FIRST, actually works pretty well. It's just too bad that Samsung removed the external sd card on the S21 series!

Backups to the external sd card & Restoring from it as well, is faster & a lot more convenient than having to use Smart Switch on your computer or restoring from a Cloud backup.

Give it two weeks and in the mean time you can set up a Bixby routine to use low power when you need maximum standby time. On S10e I can get 5 days of standby with just cell enabled, no data. Accu battery is also a good app for monitoring discharge.
