[Question] How to fix battery drain? - Redmi Note 8 Pro Questions & Answers

Hello, I'm a newbie and have been using a Redmi Note 8 Pro as my main phone. I have always experienced battery drain because of "Android System" and after reading on this forum thread I decided to use the command "adb shell top" to look at what process was actually using the CPU a lot and hogging the battery. I found out that when the phone is on with screen on (not stand-by) there is a process "[email protected]" which uses around 20-25% of the CPU. When the device is off instead there are only the various app processes which don't consume much CPU (even tho I see battery drain when I also don't use the phone).
Screenshot of what adb says when device is with screen on:

Is there a way to fix the mediatek process from draining battery? Thanks in advance, I can provide more information if you want

i didn't do a factory reset, it is updated to the latest version and the region of the phone itself is EU while in settings it's set to italy as it's where I live

is it a low percentage. either way, my guess is that process is vital for your system and for your phone. sure, you could try to find a way to lower it, but it could result in system instability.

Its the phone's radio, the one responsible for functions such as calls,messages and mobile data . it is required to maintain the phone signal . Based on the stats as the person above said its your live wallpaper causing the wake locks. Baseband xmm power is normal usage I suppose.

It can also be an alarm/notification that is causing it. I've had this issue before and it was an app that gave notifications in the background without actually showing you the notifications.
In my case I think it was the V-Pet app (my gf has nostalgia with Digimon ). Notifications were disabled but it was still sending them out hidden to the system.
Somewhere in my post history is help regarding this issue. If you need help I'll go dig that thread out

What programs are you install recently? Maybe problem is in one of them? Try to delete programs one for another which were installed recently.
But based on your screenshots (and assuming) you do use your phone from time to time than I think its fine
But do you have a custom kernel installed? If yes, have you tried to turn off pocket protection? It may help
Well i found the source of my problem. It was HTC Checkin Service that was draining my battery. Anybody know what i can do about this to fix problem? I tried greenify but that didnt work.

Try disabling the service, if ca't maybe freeze it using titanium backup?
But I think that should be some rogue app that's trying to make use of that service but I'm not very sure. I don't have that issue on sense based rom nor stock at all

I am not facing these issues but OP3 has a terrible WiFi that's for sure.
Same here, but I was able to solve. Try disable aggressive doze (I already use greenify) and startup app control in "apps". My battery is normal now, I'm on 4.0.1.

Okay. I'll disable agressive doze and app hibernation and try using greenify. Lets see. Thank u.
@tomriddle25 that's not terrible, show me as screenie when your battery hits 15% or below. My experience is that 100-85 drops really quickly and same for 50-0%
Been perfect battery life for me also, using aggressive doze and app hibernation.
An app must be causing your issue. I disabled and uninstalled greenify and my device had been flawless.

Question Google Photos consumes a lot of battery

I have recently purchased the GT Master Edition and I am doing very well. I noticed that Google Photos consumes a lot of battery, about 5%. I tried to check in the settings but the automatic start cannot be disabled, does anyone have the same problem as me or know how to fix it?

@Pippo_02
HELLO !!!!!!
I too have the same battery drain problem.
Download this app and see the "real capacity" of your battery !
https://play.google.com/store/apps/details?id=com.digibites.accubattery&hl=fr
My phone is new and I realized that I was at 45% of its real capacity !
And my phone is 100% charged
Maybe a problem with the C.06 update
The Realme has 2 batteries, so I couldn't tell you !
I think yours is a software problem. My problem is not that the battery does not last long, it is that Google photo consumes too much battery, it had even consumed 15% on 100% recharging. I solved by uninstalling it, but I would like to have it because I used it to look at photos instead of the stock app ...
@Pippo_02
If you solved the problem, great !
Otherwise, if one day you have a similar problem, in the application you have an awesome tool that shows you the discharge speed for each application, in percentage and in mA !

In the realmeUI these features are already present, without the need for third-party apps

Question Android System Battery Drain - Please Help!

Android System taking too much battery even after removal of most Android/Google / MIUI bloatware.
Will appreciate any & all help.
As of now - waiting for battery to drain to 0% and then I'll do a full charge.
Device - Poco F5
Android 13, MIUI 14.0.3 TMRINXM

Tried all suggested changes - battery drain, no background connections (internet) or activity (battery), only 2 apps in autostart.
Initially thought no network was the culprit - put in a SIM, but no changes - draining as usual.
Some forums are suggesting to update Google Play Services (currently disabled).
Only Google App/service on device - google maps
Nothing doing - any help will be appreciated.
Thanks in advance.
A few days are necessary for the system to optimize.
Look in settings/app management/installed apps/behaviour.
According to some comments, it might be a bug, Miui 14 A13, wait for the next update.

Enable back MIUI daemon in case you disabled it. I had exactly the same problem (high Android system usage after debloat) and disabled MIUI daemon was the culprit.
