Unintentional iPhone restarts are causing you pain. I understand how frustrating that is. There are many reasons why this might be happening, but there are fixes for all of them. It’s time to take control of your device and determine the cause of the problem.
Why does my iPhone keep restarting?
In my experience, software bugs are often the driving force behind an iPhone that keeps restarting. But that doesn’t mean other culprits like problematic apps or cluttered storage aren’t responsible for the mess.
Malicious third-party certifications and faulty chargers that cause iPhones to reboot themselves while charging are also common suspects.
What if your iPhone keeps restarting?
Now that you know the reason behind the problem, you might be wondering: So how do you fix an iPhone that keeps restarting? Well, these solutions have it covered:
Force restart your iPhone
Every once in a while, a random bug pops up and starts causing problems. In this case, a hard reset will usually help.
So, if your iPhone is stuck in a restart loop, the first thing you should try is to force restart it.
Update the software on your iPhone
Is your iPhone repeatedly restarting after an iOS update? If so, the problem is most likely due to a software glitch. The correct way to fix the problem is a software update.
Open Settings >> General >> Software Update. Now follow the usual procedure to download and install the software update.
Remove and reinsert the SIM card
Phones tend to get stuck in a reboot loop when a device experiences issues with its connection to the carrier. Fortunately, one of the easiest and most reliable ways to fix this connection problem is to simply remove and reinsert the SIM card.
First, turn off your iPhone. After that, use the eject tool (or safety pin) that came with your iPhone in the box to eject the SIM card tray. Remove the SIM card. After that, wait a few seconds and reinsert the SIM card.
Determine if an app is causing your iPhone to restart
If the problem continues even after a software update, find the problematic apps and remove them. So how do you find out which apps are behind this problem?
Well, iOS comes with a feature called “Analysis” which works effectively in diagnosing problems. After a thorough test, it digs out problem areas, making it a bit easier for you to figure out the culprits.
Go to Settings >> Privacy >> Analytics and improvements >> Analytics data.
Now, scroll through the entire list and locate the apps that might have repeatedly appeared. Once you’ve discovered those apps, removing them from your device might solve the problem.
Remove all outdated apps
Outdated apps tend to create a lot of problems. They can affect the overall performance of the device and even cause your iPhone to crash unexpectedly. So if your device has some apps that haven’t received love from developers in some time, be sure to remove them.
- On iOS 13 or later
In iOS 13 or later, there are several ways to remove an app. One of the easiest ways is to long-press on an app and then tap Remove app in the popup that appears. After that, tap Delete again to confirm the action.
- On iOS 12 or earlier
Just tap and hold an app and then tap the X bubble. Then tap the Delete bubble on the pop-up menu to finish.
Update all apps
Most apps receive frequent updates to improve performance and fix bugs. The best way to keep all your apps up to date is to take advantage of the “Auto Updates” feature (Settings >> App Store >> App Updates).
You can also manually update apps whenever you want. To do so, head over to App Store >> Your Profile >> Tap Update All to update all installed apps on your iPhone at once.
Clean up your iPhone
If your iPhone is still restarting, wiping the entire device can help fix the problem.
Corrupted files or overcrowded storage could be at the heart of this problem. But before you embark on this cleanup marathon, don’t forget to back up all your important files.
To help you track down all the storage-hogging files and remove them with ease, we’ve created a comprehensive guide. So, jump on it to remove unnecessary files carefully.
Do you find the process of manually deleting useless files tedious? Take a look at these iPhone storage cleaner apps.
- While I can’t say with 100% certainty, clearing the RAM might help get this problem under control.
- I also recommend that you remove any third-party certifications you may have installed on your device. Go to Settings >> General >> Profile and Device Management and delete the certificates that are displayed.
Reset all settings
We are now going to erase all existing settings and reset the device to its default state. This solution may seem a bit radical, but it often comes in handy to get rid of common problems. So, hopefully, it will be able to solve the problem.
Head to Settings on your iPhone >> General >> Reset >> Reset All Settings.
Find hardware problems
Dropping the phone a lot can also cause the iPhone to get stuck in the boot loop. If your device suffered a nasty crash recently, there could be a hardware problem.
A worn battery can also be behind the problem. If it is found to be the culprit, then you can get rid of the problem simply by replacing the faulty or worn-out battery.
If your iPhone keeps restarting while charging, make sure the Lightning port is clean. Lint, dirt, and debris in your pocket may have built up over time, preventing your smartphone from charging. So, please clean the lint and dirt stuck in the charging port and then try to charge the device. If the problem persists, try charging your device with a different cable.
Although third-party services charge much less, Apple support is more reliable. So if you don’t mind spending a few extra bucks on a reliable solution, contact Apple for help.
Restore your iPhone like new
Restoring an iPhone like new is something I usually save for last, as it’s known as the last resort when it comes to fixing software issues. It has a strong track record of resolving persistent issues like Wi-Fi and Bluetooth connectivity failures. I hope you manage to fix this issue as well.
But before proceeding to the next steps, don’t forget to back up all your data as it will erase everything on your device.
- Connect your iPhone to your PC and launch iTunes/Finder (on macOS Catalina).
- Now, locate your iPhone. After that, click Restore iPhone and confirm.
- Once it’s restored, set up your device as usual. While setting up the device, restore the device from the previous iCloud/iTunes/Finder backup.
- Now, check if the problem is gone. If so, you’re good to go! But if it’s still there, try to restore your iPhone in recovery mode (check this detailed guide).
If it’s a software issue, your iPhone should be back to normal after an update or clean restore. In the event of a hardware issue, contacting Apple Support is always the right path to a reliable solution. Of course, Apple charges much more than third-party services, but when it comes to reliability, your solution always has the upper hand.
