Batterie issue ?? If you push power button for a longer time will you see a small red light on top of device, where you notification LED’s are ? I have had this to on my Mi5sPlus. The power connector was dead and batterie wasn’t charged right. After a longer time 3 or 4 days I was able to charge it again and after an hour I was able to boot again

it was not battery problem. it was charge at 85 %
