First solution: Force restart (reboot).

A device restart is often the key to resolving minor errors and random glitches. Thus a restart or soft reset is often highlighted among the first workarounds to try on. Performing a soft reset on a smartphone clears out rogue apps and corrupted data that usually cause the system to suddenly become unstable. For an iPhone that’s stuck on infinite boot loops, restarting the system through a force restart is recommended. And here’s how it’s done:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Then, press and hold the Power button on the side of the phone and then release when the phone reboots.

If your phone managed to stay up longer after a force restart, install pending app updates and delete bad apps.

This makes it possible for you to repair system errors and restore iOS back to its normal working state.
