While the iPhone is a remarkably powerful and stable device, some people have problems with it. I know I’ve encountered times when my iPhone would randomly restart for seemingly no reason. If you’re experiencing this now, then sit back, and let’s work on it together.
Your iPhone might be randomly restarting for several different reasons. This is most commonly because an app is draining too much power or your memory is too full. Start by removing apps that are draining too much power, cleaning up your device, and restarting it to clear out junk files.
There are numerous reasons why your iPhone might be doing this. Regardless of that, we can find the solution together by taking this one step at a time. It won’t be long before your iPhone is fixed.
Remove Bad Apps
The most common reason for random iPhone restarts is that you have bad apps installed. Sometimes the app has malware, but more commonly the app is draining too much battery power.
While you can remove any new apps that you installed, this often isn’t the best way because it might be an old app that you haven’t updated. I will show you how to check which apps are taking the most battery power.
You also don’t need to completely remove the app. Sometimes a simple upgrade is all that’s needed to correct this issue.
Check Battery Usage
Turn on your device and select “Settings” from the Home screen. Select “Battery” and then “Show Activity.” This will show you various apps and background procedures that require battery power.
Tap on “Show Detailed Usage.” This will break down how much battery power each app is using. I prefer to tap “Battery Usage” here as it will show you the percentage of battery life each app requires.
You can choose to view battery usage over the last 24 hours or 10 days. There are currently no other views, but this can always change with an operating system update.
You are looking for apps that are taking excess amounts of battery life. For example, if a relatively small app like a calculator takes 40 percent of your battery life, then you know it’s a problem.
Correcting the Issue
There are two things you can do here. You can choose to delete the app or update it.
Deleting the app will fix the problem permanently, but it means you can’t use the program again without reinstalling it. You can do this by tapping and holding the app’s icon.
After a few seconds, it will wiggle and an “X” will appear in the corner. Tap the X to remove the app. It is now deleted from your iPhone.
You can also update it. Go to the App Store and search for the app. You will see a button to update the app. Select this button and the new version will download. This will often correct the problem, but there is a chance that it won’t.
If the update doesn’t solve the issue, then delete the app.
This tends to be a problem with older iPhones, but it may also happen with current models. If your iPhone’s storage is too full, then it can mess up your device in numerous ways.
Aside from not being able to save more files or download apps, you will also notice that your device moves slower and the battery drains quicker. Another possible issue is that your device will keep restarting.
There are several ways to fix this. While iPhone doesn’t have expandable storage, there are options for saving your files or removing them completely.
Delete Unneeded Files
The most straightforward way of fixing this problem is deleting unnecessary files. You probably have numerous files on your device that you don’t need. Every file you delete frees up some of the storage space.
I suggest taking a look at the largest files first. Go through the file explorer and look for video files and game apps that you no longer need. You can also delete messages, pictures and other files to free up some space.
Keep doing this until you have at least 1GB of free space available. This should be enough to tell you if storage is responsible for your device restarting.
While iPhones may not have expandable storage, there are ways of saving your files away from your device. Cloud storage allows you to save the files elsewhere so that they don’t impact the iPhone’s storage, but you can still access them.
You should have iCloud storage on your device. If you don’t, then download the iCloud app and then move some files over there. You can access these files whenever you need them, so remove them from your device.
There are numerous other cloud storage providers as well. You can use multiple ones as needed to ensure that your phone’s storage isn’t clogged.
Update the Operating System
Apple is consistently releasing new iOS versions. While some people groan about updating their device, especially since there might be changes you don’t like, it’s always good to keep your device up to date.
Failing to update the operating system means that there might be security holes and software problems. These issues might result in your phone randomly restarting. Updating the operating system might be exactly what you need to prevent this from happening.
There are two ways of updating the OS. The easiest and most straightforward way is by going to the “Software Update” tool.
Go to your Home screen and then select “Settings.” Select “General” and then “Software Update.”
This will then search for a new iOS version. If one is available, then you will be able to download and install it. The problem though is that the device needs time to download the OS, and these files tend to be quite large.
If the random restarts aren’t that frequent, then this might be fine. If it’s happening several times a day, then this could be an issue.
You can manually download and install the new iOS version. Open either iTunes or Mac App Store, depending on which Apple OS you’re running, and search for the newest iOS version.
Connect your device and download the new iOS version. This allows your computer to be responsible for most of the downloading, and it will help with the installation as well. Once completed, you can then decide to update iOS on the device.
This should correct the restarting problem if it’s from an old operating system.
