Installed Xiaomi.EU Rom on my 12s Ultra the day it came out and it's awesome!

However, I have been having problems with battery drain compared to the CN rom. I attached two pics (different days) of light usage. From what I've seen with people on CN rom, the usage of Google Play Services is super low, less than 1%, while I'm sitting at around 10%.

I've tried clearing data and cache for Google play service and re-adding my account but still didn't help. From what I understand, many apps use google play services and their usage is combined... so maybe it could be a single app I don't know about?

Is it just me or should I be getting better? Any ideas? What are you guys getting?

I have the same problem, I think it's because of the China Miui 13 ROM, both my mi 10T pro and 12s ultra have this problem

What's weird is people using the China ROM from what I've seen are getting good battery life. I've seen people 10+ hours screen on time with 12s ultra cn ROM.

I have used cn ROM for around a week. But I couldn't feel it had good battery life. Just similar as the eu rom

I hvae this exact same issue on my Mi 11 Ultra, official Global rom / set.

What i did was goto apps, google play services, uninstall update, clear all data.
then reinstall again, and had to resetup some google stuffs.. that seems to have solved my issue.

My mi 11u was draining over 10% overngiht and it never went to deep sleep!

Yes, I felt the same way, but I'm not sure since I didn't take notes about how long my battery lasted before installing xiaomi.eu rom.
