IPhone – Phone wakes up a few minutes after every text message. Can I make that stop

It's nothing to do with your iphone it's generally an option on your stereo settings. On my ford fusion, I can select between two apps - Podcasts and Music. I guess it depends on whether your stereo was precisely developed for iPhone or it is generic for any other bluetooth connection.

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:

1. Make sure your iDevice is plugged into a power source via it's USB cable;
2. Hold down both Home and Power buttons on the iDevice for about 10 seconds until the screen goes off;
3. Keep holding the Home button and release the Power button;
4. Open iTunes to check if the iDevice is connected. A message saying that an iDevice in a Recovery mode is connected should show up.
