iPhone that won't turn on or charge

Option 4 worked for me....

If the iPhone did not turn on, try resetting it while connected to the iPhone USB power adapter. To reset, press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until either the Apple logo or the battery symbol appears.

Excellent.kudos to step 5. It worked. Thanks a ton.

Man you saved my day, lots of time and $$$. I thought my Iphone5 was dead even though I knew it was 45% charged. Tried #5 and it came back alive with Apple Logo and showing 90% charged (as it was plugged to the charger). Thanks a million 🙂🙂😎

Ok, this is too late to help, but I thought I'd answer anyway in case someone else finds this post whilst searching for the problem. Here's how to fix it:

Lithium batteries have protection against over-discharging, they do this by breaking the circuit if the voltage drops too low to prevent further drain. Unfortunately, once this has triggered, you can no longer put charge back into the battery because the battery is disconnected internally, so no matter how long you leave the phone on charge, it remains disconnected and flat.

You only need to get the voltage in the battery to raise a percent or two to reconnect the protection circuit so that it will charge again and you can do that by warming up the battery. You may get away with leaving the phone overnight in a very warm (hot) place, such as on top of a hot water tank, however a more efficient way is to remove the battery and heat it up until it's quite hot with a hairdryer on its hottest setting. Heat it for a good 5-10 mins so that the hear soaks right through the battery and it feels hot to the touch, this will raise the internal voltage enough to reconnect the protection circuit. Immediately reconnect the battery into the phone and put it on charge. After about 10-20 mins, enough charge should get back into the battery to fire up the phone and it'll come back to life.

I've done this a few times now on various different models and it always works. Hope it helps yo

Thank you just found this post and what you suggested worked great #5 a million thanks.
