S4 Mini suddenly died

[mikerelvasr8]

Hello everyone,

My dad owns an S4 Mini for just over two years. The phone has worked fine the whole time and it has been taken good care of, but all of a sudden it died. He charged the phone completely and unplugged it from the charger before he went to bed. The next morning when he woke up the phone was no longer working, it wouldn't turn on nor would the screen turn on when being charged. What do you guys think happened to it? Is it possible and/or worth fixing or is it trashed? It is not the first S4 Mini I see doing this, but it is very strange nonetheless as it is completely random.

Thanks in advance,
Cheers

The first thing to try is a new or different battery. Any piece of tech can fail without warning, especially as it ages. It could be the battery, the power switch, or the motherboard.

Maybe I should give that a try, but I'm not convinced it is the battery. It probably is the motherboard. Thank you so much for the help!

Long pressing (press & hold) Power button fails? If so, I'd take battery out and leave it out awhile. Charge it up full outside the phone if you have a way to do so. Then replace it and try (1) Home button, (2) Power button quick release, and (3) Power button long hold until phone (hopefully) vibrates and boots.

Hey,

Thanks for your help first of all. Yes, I have done all those things and it doesn't seem to affect anything. The phone is completely dead. :/

This happened to me exactly last week
one technician said it is due to dead Power IC after checking the phone with a power supply, it did not draw any current. I do not know if that is the cause, but I have to order one and check.
