Yet another battery drain post

[CHMultimedia]

Because having battery issues is trendy...
Hellow there. Let's cut to the chase. My trusty S7 has chosen to take part in the battery drain trend, without my consent. Used to last me longer... It would be great if anyone could help me.
Note that the M1 cores do enter sleep mode as I pointed out last time. Rest assured, cache clearing from the Recovery boot menu is a step I have taken on multiple occasions.
There's a screenshot of the battery usage screen enclosed, but is in French so here's a translated version.
1- Screen (3h33 SOT) 23%
2- Android System 16%
3- System UI (AOD) 8%
4- Device Idle 7%
5- Android OS 6%
6- Light Manager 5% (this is normal though)
7- audioserver 3%
8- mediaserver 2%
9- media.codec ( I assume HW decoding from watching very high quality, high compression videos) 2%
10- Cell Standby 2%
11- S Internet 1%
The only really unusual part is the Android System part. And you know, only 3 hours SOT.

That's where using apps like BBS - Wakelock Detector & GSam Battery Monitor help you to find the apps that are misbehaving 🐧

Someone in the US Samsung forum disabled volte and got better battery life. Possible that might be a factor?

Hey everyone I think it has something to do if you have developer options enabled. Tried everything everyone suggested and when I factory reset my phone a second time I did not enable developer options. It's back to normal. Hope it will work for all of you.
