Wa **** , my phone something got this twice . this time i cant even power on.
I didnt install anything recently , is it the new update abit off
your post 26 april
now 15 may I encounter the same "cannot boot" problem without any pre-failure symptom
still cannot find any fix , tried the tapping compress method on youtube to push back any loose connector ... cannot work
from google search and youtube , seems like the hardware failure can be more than just battery ... youtube many comments same problem with redmi 1-2 years ago
youtube ppl save money will heat up the cpu or power chip to resolder .... too high skill for me ....
personally i guess battery or motherboard fail due to prolonged video watching @ high brightness & simultaneous charging while inside phone casing trap heat .... cooked to death .... or accumulated drop damage
from plugging in a slow charger for hour+ can feel slight warmth at the top electronics area above the cool battery area
