New mi 11... Battery is ridicilous. Other is almost 500 mah??? EU phone miui 12.5.1 . Will this solve itself over time??? If not someone have an advice?
Wait a week while your phone learns how you use it.
You have many tweak you can disable with miui for battery saving.
Afterwards, you will have some advanced tweak for your phone to save battery.
Debloat...
Root...
Naptime/servicely...
Or flash a GSI rom for best result...
But one thing at a time. You have new phone. Take your time.
(but you will understand that mi 11 doesn't have a good battery life in fact)
Unlikely it will get better... even if does it will likely cause erratic behavior and more battery consumption than if you directly addressed the problem apks.
Don't know though with that platform.
I disable all power management and deal with the battery hogs on a case by case basis.
