Doesn't wake up after sleep mode
Hi, iPhone 5c doesn't wake up after some time in sleep mode.
As long as it's in wake mode everything works normal. But when I press the sleep/power button it won't wake up after 5-10 minutes. Within 5 minutes it will wake up... After 5 - 10 minutes it doesn't turn on until I boot it up again .
There is nothing wrong with the buttons, screen or battery. I also can't find shorts.
Any ideas? Thanks!
