I borrowed a friend's old iPhone that is now essentially an iPod Touch. I used it for several hours to listen to music without any issues and then put it in my pocket. One thing I didn't do was turn it off. Not having one I thought it would go to sleep or something.
Anyway, not it doesn't turn on. Charging doesn't help. I didn't drop it or get any moisture on it. The only things I did were: 1) not turn it off, 2) left the ear buds in with the cord wrapped around it when I put it in my pocket, and 3) attempt to charge it later that night on my laptop.
Any idea what I could have done to it? She said she's drained the battery many times and that has never been an issue.
She's taking it to the Apple store over the weekend, but I feel bad because it stopped working while I had my hands on it.
