New Battery drain miui 11 redmi k20

[salvatore999]

I have a mi 9t, after upgrading to miui 11, the battery life has decreased a lot, the "Android System" element is always in first place in the use of the battery and the reported usage time is always greater than that of the screen.
Before the update I could also have 9 hours of screen on with LTE and sync always active during use, now if it goes well I arrive at 4 hours, watching on the Internet I saw that this is a widespread problem.
Does anyone know how to solve this problem?

[giodeluigi]

I'm experiencing same drain here..
I'm losing 7% overnight even with the phone in flight mode..
MIUI 11 stable, clean install.
Don't know why.
MIUI 11 weekly on Android 10 had bugs but battery was great.
Any help?

7% over night? I was losing 5% in an hour.. 7% over night is not much

During the night in flight mode?

 

[giodeluigi]

I lost 10% last night.
Flight mode, everything off.
Wifi off.
It seems too much for me.
Are this normal values for Xiaomi Mi 9T under MIUI 11 Stable?

In MIUI 11 global ROM, I had 3% drain over 7 hours at night with flight mode and battery saver, with last xiaomi.eu stable ROM I have over 10% drain

Never lost this amount of battery overnight with any of my previous mobile phones, mainly Samsung.
I think 10% overnight is a really high amount for an optimized custom ROM.
MIUI 11 Weekly (based on Android 10) seeemed to drain less battery.
I hope this will be fixed in next stable build.

Check the results I found here:

https://xiaomi.eu/community/threads/about-drain-in-stand-by-9-11-14-weekly-rom.53446/

same result 0.3%/h with latest 9.11.28.
Airplane mode Off.
Something is drilling a process in your phone background. Find it!

Really impressive and in-line with the battery consumption I had in the past.
I don't really know what can cause this trouble in my phone.
BetterBatteryStats seem ok..
Anyway you're on weekly over Android 10 and here I'm on stable.
My doubt was related to stable.
Anyone has the same problem on stable here?

 

[salvatore999]

I tried to update with the latest weekly rom build but the problem remains and is not solved I don't know what this battery drain might be due to but it's very annoying, isn't there a way to solve it?

Have you tried my solution? Flashing official rom with miflash

 

[davidjarod]

it didn't work, follow the high consumption of android system

 

[giodeluigi]

Same drain here.
Tried many things here; BetterBatteryStats, Wakelock Detector, Naptime, Greenify.
Their statistics and values seem OK so I think it high battery consuming from the source.
Hope this will be fixed in next build.

Yes, before having xiaomi.eu I flashed the official MIUI 11 with mi flash, but the battery drain was still present, so I went back to xiaomi.eu in the hope that with the weekly updates this bug would be solved, but it is still there

am I wrong or with the miui 10 there wasn't this battery drain?

 

[giodeluigi]

Dunno.
This is the first time I got this battery drain (with Stable MIUI 11, Android 9 here on Mi 9T).
Before I was on Weekly (MIUI 11, Android 10) and the battery drain was not present.

 

[deftozzz]

I have this exact problem on weekly! I have tried to install global rom trought fastboot, then twrp and weekly xiaomi eu rom (clean flash ofc).
I have turned off xiaomi find me, google backup, xiami backup an android system eats my battery out

 

[davidjarod]

This is not normal, I have a redmi k20, beta 9.11.28

 

[giodeluigi]

I'm on Weekly 9.11.28 too now and the battery drain seems gone.
Stable always lost 7/10% overnight, Weekly 1%. Same configuration.
Dirty updated from Stable.
Didn't clean cache/dalvik, just reboot.
My opinion is that MIUI 11 Stable based on Android 9 is a battery eater for Mi 9T.
This rom currently suffers a boring Instagram bug (cannot post any 15 seconds longer video on stories) but for now I can deal with it because the battery finally turned good.

so could I try to clean everything with a full wipe and install 9.11.28? maybe the battery drain also disappears to me

 

[giodeluigi]

Battery drain is back with Weekly 9.12.12 here..
7% overnight again with airplane mode on and everything else off.
