How to Fix Your iPhone When it Keeps Restarting?

What to Do if Your iPhone Keeps Restarting?

You're reading an article on the internet or talking on facetime with someone, and suddenly your iPhone screen goes black. Your device has just restarted itself. A few minutes pass, and it restarts itself again. Suddenly, your iPhone is stuck in a reboot loop, and you have no idea why.

How to Fix Your iPhone When it Keeps Restarting?

Believe it or not, this issue is quite common, not only with iPhones but also with other brand models. Usually, the reason for the constant restart of your device is either a software bug or mechanical damage. If it's a software bug, there's not much you can do but wait for Apple to release an update or contact them and as about the issue.

If hardware is damaged, you have two options. Either get the damaged parts replaced, which can be very expensive, or buy a new iPhone.

Sometimes, a faulty charger cable or dirty lighting port can cause a reboot loop. In this case, change the charging cable or take your iPhone to the Apple store to clean the port.

Check for External Damage

If your iPhone has experienced a few crashes to the ground, the hardware might be seriously damaged. The damage done to the device can cause reboot loops. If nothing helps and you see visible damage on your iPhone, take it to an authorized service to get it inspected.

If constant restarting happens when the iPhone is charging, check if the lightning port is not dirty. If you see any debris, we don't recommend cleaning it yourself unless you know what you're doing, as you can easily damage the port. Take it an authorized service or an Apple store.
