One of the most prevalent concerns that arose after an update installation was rapid battery depletion. This is frequently caused by rogue programs that revved up the CPU to its highest setting and then caused excessive power consumption. As a result, the battery is completely depleted, and the phone is no longer functional. You may believe that the gadget has been trapped on a dark screen, but the truth is that it has run out of battery. If this is the case, the only method to get your phone working again is to charge it. As a result, put your iPhone SE into the charger and wait at least an hour for it to charge. Check to see whether your iPhone can be charged. If it doesn't charge, you'll need to address the problem first.

Force it to restart while it's charging by pressing and holding the Power and Home buttons for a few seconds (at least 10 seconds), then releasing both keys when the Apple logo shows. This will assist in the removal of any errant background programs and corrupted cache that may have caused the phone system to malfunction.
