Can i mess the Batterie voltage? Or other Idea?
No i can´t send it back to the seller ...=(
As you already opened phone you can disconnect and reconnect battery. Then connect charger and wait to fully charged. After few minutes you should get red notification light if this not happen please check different charger and USB cable.

This battery can handle up to 4,4V but charging voltage supplied to phone can be up to 12V and 1A, on 7V 1.6A,.
Charging time is depending charging current. If you charge with 5V and 1A you need charge nearly 3h and 45 min to 4 hours.
The Prob is that the Battery is full. It was full i look FB and Insta turn the screen off not the phone. Go away for 2 min came back and since than nothing.
The first and last Umi the first Problem after 3 moth and than after 1 year this.... Updates sucks Umi support sucks (original support after the first problem) but every Month a new Phone nice try UMI -,-
