S21 Ultra - Terrible battery

[mariyantest3]

Hello,

I have issues with my battery too (exynos version). I don't think that 5000mAh are enough only for 3-4 hours SoT in the best scenario. Yes, I charged my phone on 2 days but I can acheve only around 3h SoT.  I'm not person who are playing games or watching videos. The device is using only for standard things: social browsing, checking mails, calls and smart watch connection. GPS connection is disabled by default.  In battery section my top usage app is : "Google Play services". For example : Today I already lost 25% with 40 min SOT which is not good, if I'm right? Already tried everything as put apps in deep sleep and  etc. Already tried to stop a lot of things from settings but by I don't think that is normal for device in this price range (a.k.a. flagship). The only thing that I didn't try is factory reset but I'm not sure that this will help me.  I don't know how the other users are have 7-8-9 SoT.  

Any advice?

Thank you!

hi have you tried a partition cache wipe

[mariyantest3]

Yes, after AUB8 I tried this. After that I received AUB9 and didn't clear cache again because I think this wasn't help me on AUB8.

try clearing partition again i always do it after every update also did you say google play services are running in background because that will also drain your battery fast.

[mariyantest3]

I will try this later. It's strange why Google Play services are draining so hard the battery on background. I asked local (and after that global) samsung support about that and they didn't say anything for this service.

I do it after every update,I mean my battery life is awesome get easily 11 hours sot if I don't play games.

[mariyantest3]

What... 11 hours sounds like a impossible. If I get 4 hours SoT will be as win. Do you use mobile data/wifi, bluetooth  and sync options?

[tinglish]

yeah my WiFi and mobile data are always on,I only turn Bluetooth on when I need it.i have it on 120hz plus wqhd.
it does sound like Google play is causing some of your problems.heres mine it hardly uses any battery

[nowdeleted]

there is quite a few things you can do as I've commented before

adaptive brightness... turn off and manually turn down the brightness
put apps to sleep to sleep including bixby if used
turn off bluetooth if not used and looking for a WiFi signal also decreases the battery life
finally.. dark mode will help

this is my battery at the minute
