Battery discharge after system last update on S21

[Members_3pDAzck]

Hello everyone,

I have been reading quite a lot on this subject and tried many options alrerady but nothing seems to be working. I have an S21 and I installed the last system update One UI 6.1. Since then the battery quickly discharge (using the phone in about 10 min, without using it in about 20 min). I have tried to reset it to factory, but didn't work. I also tried to clear wipe cache, but didn't change anything. I removed all apps I had, cleared the apps cache also but nothing changed either.  I really don't know what do to now and I don't want to buy a new phone since this one was perfectly working before the system update. Any help ?

Hey there and welcome to the Samsung UK and EU Community Forum

Are you suggesting that your device goes from 100% to flat in 20 minutes?

Yes absolutely but it didn't act like that before the update 😞

Care to go to the "device Care" and then battery-share that screenshot of it happening?

In addition to what @johnz237 has asked, can you also please post a screen shot of your battery usage?

Here are the different screenshots around the battery system I just took. Everything shows as being optimized.

Here is the battery usage, I guess. My phone is in French and not everything is an easy translation. It turned off many times already this morning. Hope this help.
