How to fix Samsung Galaxy Keeps Restarting after update
Solution 1 : Charge Your Phone And Observe
The first thing you need to do is to rule out the possibility that your phone has a defective battery. If it’s an issue with the battery then your Galaxy S21 should not reboot by itself, when it’s connected to the charger as it’s getting power from the adapter and not the battery. So plug the charger to a working outlet. Connect your phone to it using the original charging cable.
