Battery drain after the last security update (September update) on S21

[Michael2103]

Is anyone experiencing the same issue as the title suggested? It's been more than three weeks now and my battery is getting worse after the last security patch/update pushed in September. 

I am fed with Samsung phones.

The battery used to last about 18hours on battery saving mode and 12 on optimised. Now I can't make it through 8hours both on optimised and battery saving mode.

It is sad and frustrating. The update makes my phone heats up quicker than it should have. I am sorry I wish I could offer you a solution to this. I have wiped my phone and it is worse, sad to say I have lost half of my data to a bad security update

So sorry to hear you have lost half your data, this shouldn't be happening plus the phone heating up, that's a concern too. When you contact Samsung they don't help with the issue if I'm honest. Just talk you through the usual jargon which never resolves it!
I really hope this gets sorted for those of us that have been effected.

Samsung is terrible at resolving issues.

Same issues here with the October Security Patch. I am currently at 23% and its not even 5pm yet.

October seems to be better for me... but notice some sort of a lag and the screen sometimes freezes when browsing my apps
