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!
Was it water damaged? Have you tried hard reset? This is known issue when the power flat was loosing contact, but you say it isn’t hardware issue… If software doesn’t work, I would bet on motherboard problem…
