IPhone turned off and won't turn back on

I have an iPhone 4 and I was on Instagram and it just randomly shut off and now it won't turn back on. I tried to plug it in to the charger and nothing happened. I also tried plugging it in to my computer and nothing happened. Then, I tried holding the home and on buttons at the same time, and still nothing! Please help, I use this phone for everything from work to college and I need it!

How long was it plugged in? Usually it takes 5-10 minutes for it to turn back on. Wait a while: it could have died and just needs some charging time, or it coould have over heated and needs to cool down.

If you have done all those and still nothing happens, your phone hardware may be broken or your cable is bad or your charger is not working anymore. Try to borrow a cable and a charger, see if it works. If not, I guess you need to have your iphone repaired.

  • My Iphone 5 turned off and won't turn back on? I was just in the middle of checking facebook after texting my boyfriend. My phone went black like it had shut off but no Apple image appeared. Now the phone will not turn on nor will it show any insignia when I plug it into a charger or anything. Please help me! I tried holding down the home and lock buttons (a reset) and that didn't work either.
