New Mi9 9.12.27 huge baterry drain

[xdauser]

It seems that only Mi9 series devices is affected by that. Battery drain seems to be caused by google play services according to GSam Battery Monitor.
The last stable version for me was 9.8.1 where I had 2% battery consumption per hour. Now it is 10 to 15% per hour and phone runs quite warm. All consecutive ROMS afer 9.8.1 seems to have this issue. In the latest ROM 9.12.27 there were several cases already called on forum.

Try factory reset. I don't have your kind of problem.

Have you waited couple battery cycles?

 

[xdauser]

Nope but I do not see any reason why.

For me it's around 2-3 %/h.
Try to wait for a battery cycle or two and a reboot sometimes makes magic.

Thanks for your advice. I will try this on the next version ROM.

I also recommend to either manual upgrade Google play service to the most recent version or clear all of its data even the setup is new, the incorporated version is most likely outdated and sometimes the background upgrade process is responsible for the mentioned symptoms, the Rom is not to blame, this happens also on official releases on occasion.

I have issues with battery drain after the last update of xiaomi.eu weekly due to cell standby - system battery usage.

Googl Play is OK here...

Any idea what to do or just wait for next update?

I did a clean flash, format data.

Me too only happened to me after last update.

As in earlier version (Android 9) it seems that the default settings for preferred network type do not fit the needs of some users.
At least I had to change them to LTE/CDMA/UMTS auto. Since then I have almost no drain through cell standby.
Just as a hint.

Since the last update it's not possible to save the changes. I used to have setting to LTE/WCDMA which was better for battery drain, but after the last update it's changed back to default with every reboot. Before the settings were save and not changed after a reboot.

Yes. these settings - especially whet set via USSD code have to be reset after reboot.
With Android 10 these problem was gone until it came back with one of the last versions. I don't know which one.

But your question was about batter drain caused by cell standby. So this might be a solution. Use it or not.
