iPhone, iPod, iPad Power issues checklist
- iPhone won't power up
- Don't panic, more often than not more damage is done by panicing and typically blitzing the phone :(
- Try plug the phone in to the charger and see if that brings it to life, if it does then you probably have a dead lock/power button
- Try a different data lead
- Try a different charger ( or plug in to the PC )
- Does the phone respond to mute/unmute, or incoming calls ( if so, that's a good thing )
- If the phone shows up on the PC then that's a good sign, might just be a disconnected lead in the display
- Try a hard-reset, press the lock + home button together for about 15 seconds or until the Apple logo reappears
- If you find that no matter how long you charge it, it never gets beyond a few percent charged, then likely you have a dead battery
