So make sure the battery is fully charged before you start the upgrade. If you find that your iPhone will not turn on, check the device battery first and charge your phone to see if it will turn on again.

 

 

Potential Cause #2 - iOS Crash

If you are sure that battery power is not the cause resulting in your iPhone not turning on, then you might need to check if the iOS has been crashed. You can figure it out by performing a hard reset on the iPhone. In general, a hard reset can fix quite a lot of issues such as frozen screen and device initiation failure. So it is worth a try if iPhone will not turn on
