BIG BATTERY PROBLEM

[ZEVS]

Battery problem after upgrading to Android 10 on Samsung m30s.

After 10 hours, 40% of the battery's charge disappears. I think that messages app do this. Samsung - you must fix this. It is India region. Fix it in update to android 10 for all regions. Camera in 48 mp mode do not have zoom and flashlight.

how did you update your device software? it's by firmware flash or simply you install it by mobile data? 🤔

[RJ96]

downloading and installing it through phone is the safest way.
Settings>>Software update>>Download and install

It is by firmware flash with Odin

[ZEVS]

Can be this problem connected with installing firmware with Odin?

[RJ96]

Yes. You probably have spoiled your operating system software by installing it via odin.
Let me guess you got impatient and hurriedly installed the new update even before it was offered to your phone via samsung software update officially.

Download samsung kies on laptop/Pc and do a emergency firmware recovery to restore it back.

it might be the data notification popup it keeps screen on of the phone continuously and it drains battery. check which comapny sim card do you use.? It happens on my Vodafone sim sometimes.
