Why would my iPhone 6 be stuck in a dead battery boot loop?
Okay, so I have a problem. My iPhone 6 died (it runs a non-jailbroken version of iOS, I used it as a test device for development applications, but I didn't do anything crazy with the firmware of the phone). I plugged the phone in and got an Apple logo, and then it died again. It's on a loop.
What it looks like is happening is, when the phone is charging, it's above 5% battery, so it turns on. However, for some odd reason, the phone doesn't turn on all the way when it boots up; instead, it just shuts off again.
Then the phone goes back to "charging from dead" again. It's in an infinite loop.
Why would this suddenly happen? It's an unjailbroken iPhone 6 running the latest iOS (non-beta, iOS 8.4). How would I fix this?
Solution 1:
In such cases I, myself, do a boot into DFU mode which actually uses way less energy mainly because the display stays off. Then I wait for about a half an hour and then I reboot the iDevice in order to have it properly booted.
P.S. Follow this procedure in order to enter an iDevice into DFU mode:
- Make sure your iDevice is plugged into a power source via it's USB cable;
- Hold down both Home and Power buttons on the iDevice for about 10 seconds until the screen goes off;
- Keep holding the Home button and release the Power button;
- Open iTunes to check if the iDevice is connected. A message saying that an iDevice in a Recovery mode is connected should show up.
Solution 2:
Its a software bug it should not boot until the battery is strong enough. Instead it boots to soon and the screen stays on keeping the battery from charging.
Fix one if it does come up to the unlock screen quickly unlock it and then off the screen it will then stop rebooting and charge up.
Fix 2 if you cant get it unlocked hold down the home screen while rebooting and leave it on the screen that says to connect to itunes. Let it charge on this screen with a original charger and cord.
Remember its the screen being on thats stopping it from charging.
This is a defect in the current OS its not reading you battery voltage and rebooting to soon. Ours only started doing this after the latest OS update.
