Battery drain in Samsung M21

[Chanakya_Reddy]

Hello Samsung, Please fix battery drain and excessive RAM usage problem in Samsung M21. A minimum of 3gb RAM is always in use. For night time, even when I not use the phone it drains by 10%. I always clear background apps in device care. I have tried hard reset and everything. I always disable bloatware apps and I always try to keep my device clean. Please fix this as soon as possible. This problem doesn't exist in One UI 2.5. This problem started just after updating my device to One UI 3.0. I have been sending error reports from 6 months but still not fixed. Please fix this problem as soon as possible.

4-5 hours

Go to device care>battery and see which apps are draining most battery. Then put those apps in sleep or deep sleep

Google play services is draining more. It is active in background for 1d 12 hrs. I can't see it in apps list to put it in sleep.

Go to seetings>apps> find google play services >restrict background data usage

Let me provide you with the solution.
Do one thing.
Take backup of all your contacts , images , accounts , personal info
And factory reset it. It will perform better than before after factory reset. This problem happens after major os update but factory reset will solve your issue. And after that install galaxy labs from sammobile latest version is of 5 months before. Install app booster , battery guardian from sammobile as a plugin for galaxy labs. Performance will be increased by 15% , and battery time will also increase. Accept this as solution afterwards.

I get a good SOT commensurate with the battery capacity but yes idle RAM consumption has been way too much after the android 11 update

And my friend too was complaining about the battery drain
