"My iPhone will not turn on after several hours of charging. HELP?"に関する回答WOW!!! This was a lifesaver for my phone. My phone battery died when I left youtube on all night. It didn’t want to charge after that, the dreaded black screen was in command. Thanks for this tip!! I didn’t have a blower so I heated it a bit from the heat coming off my laptop, then when it got some heat, I charged it and it worked!
