Why Does My iPhone Keep Restarting?

Random restarts on your iPhone can be caused by a variety of factors, both software and hardware related. On the software side, it could be due to a buggy app or an issue with the Android operating system itself.

Hardware-wise, it could be a sign of a failing battery or other hardware component. Regardless of the cause, random restarts are certainly annoying and can be difficult to troubleshoot.

There are a few potential causes of random restarts on modern devices. Malware, software update bugs, and rogue apps can all trigger this issue. Random restarts can also be linked to battery draining symptoms.

In worst cases, random restarts can be a sign of more serious hardware damage. For example, if your device falls and receives physical damage, or is exposed to liquid, this can cause problems with the hardware and lead to random restarts.

Often times in order to deal with hardware-related issues, physical repair is needed. Before rushing to a service center, performing some applicable troubleshooting methods is highly recommended in order to rule out software-related issues.

Some common hardware-related issues include a cracked screen, malfunctioning buttons, or a faulty charging port. Cracked screens can usually be replaced by following a tutorial online or visiting a service center.

Malfunctioning buttons can often be fixed by taking the device apart and cleaning the button mechanism. A broken charging port generally requires soldering on a new one, which should only be attempted by those with experience.

Troubleshooting software-related issues can often be done by restarting the device, clearing the cache, or resetting the device to factory settings. If these methods do not work, then contacting customer support or taking the device to a service center may be necessary.

Uninstall Bad Apps

Rogue apps are often the culprit behind random restarts on mobile devices. To rule out this possibility, check your iPhone storage and see which apps are using up a significant amount of power.

One way to check which apps are using up the most power is to go to the Settings app, then tap on Battery. Here, you’ll see a list of apps and the percentage of battery power each one is using.

If you see an app that you don’t recognize or that you rarely use taking up a lot of power, it’s possible that it’s a rogue app. You can remove these kinds of apps by holding down on their icon until they start wiggling, then tapping on the X that appears.

The apps that are draining the most battery on your iPhone should be updated, otherwise deleted. This is because these apps are likely not optimized for the latest iOS version, and thus are using up more battery power. By keeping them updated, you can ensure that they are running as efficiently as possible.

Apps that use more power than usual can often lead to battery drainage and unexpected shutdowns. To deal with these bad apps, you can either update them or delete them completely.

Updating an app can sometimes fix power usage issues, as new updates often include bug fixes and performance improvements. If updating an app doesn’t help, then deleting it may be the best solution.

Manage iPhone Storage

One potential solution to random restarts on an iPhone is freeing up some space on the device. This can be done by deleting unused apps and files, or by transferring data to a computer or external storage. If there is not enough free storage on the iPhone, it may cause the device to restart randomly.

Navigate to your iPhone’s storage and memory and if you can delete apps you no longer utilize, messages, or photos this can help free up space and fix issues related to your iPhone randomly restarting.

To access the storage and memory statistics on your iPhone, go to Settings > General > iPhone Storage.

Here, you can see how much space is being used by each app, as well as by system files. The break-down of space usage by app includes both the app itself and its associated data and documents.

You can also see how much space is being used for photos and videos, for mail, for iCloud backups, and for other files.

If you tap on an app in the list, you will see more detailed information about its usage, including the option to Offload the app. This frees up space on your device without deleting the app or its data.

To access memory statistics, go to Settings > General > Usage > Manage Storage. Here, you can see how much space is being used by each app, as well as by system files. The break-down of space usage by app includes both the app itself and its associated data and documents.

Update the Latest iOS Software

There are a few reasons why updating to the latest iOS software could prevent an iPhone from randomly restarting. First, Apple often releases updates that include bug fixes for issues that could cause iPhones to restart randomly.

So, if there was a bug that was causing this issue, it’s likely that updating to the latest iOS software would fix it. Second, Apple also frequently adds new features and improvements with each iOS update.

This means that the overall stability of the operating system is usually increased with each new release. Therefore, it’s also likely that updating to the latest iOS software would help to stabilize an iPhone and prevent it from restarting randomly.

In order to check for updates, open the Settings app and tap on General. Scroll down to Software Update and tap on it. If there is an update available, you will be able to download it and install it from there.

iOS Update Notification

When a new iOS update is available, an update notification will show up on your iPhone. The notification will provide information about the new iOS version, and will give you the option to download and install the update.

However, there is no guarantee that over-the-air update installation will be completed, since your iPhone may shut down and reboot on its own.

Because of this, using iTunes to update your iPhone is the best solution.

When updating your iPhone through iTunes, there are a few key things you should keep in mind. First, make sure you have a computer ready – either Windows or Mac – and connect your iPhone via Lightning cable or USB connector.

Once you’ve launched iTunes, it will sync with your iOS device automatically. During this process, any changes you’ve made to your iPhone since the last sync will be backed up onto your computer.

Additionally, any new content or updates available for your iPhone will be installed during the sync process.

If you decide to manually update your iPhone using iTunes, make sure you are using the latest version of iTunes. Also, it is important to check that your computer has a stable Internet connection in order to avoid system conflicts. After updating, reboot your iPhone to apply the recent changes and clear out any software glitches.

Update your iPhone Apps

iOS apps are usually automatically updated when a new version is released, as long as you have the auto app update enabled. Updates can potentially fix the problem if rogue apps are the main trigger. Out-of-date apps are more likely to get rogue, so updating your apps regularly can help to prevent this issue.

iOS app developers regularly push out updates to their apps in order to keep them optimized and bug-free. If you have not configured your apps to automatically update, then you can manually check for and install pending app updates on your iPhone.

To manually check for pending app updates on your iPhone, open the App Store and tap the Updates tab at the bottom of the screen. If there are any updates available for your installed apps, they will be listed here. To install an update, just tap the Update button next to it’s entry in the list.

How to enable auto app updates:

One way is to go to the App Store and enable updates under automatic downloads. To do this, open the App Store and tap on the Updates tab. Then, find the Automatic Downloads section and toggle the switch next to Apps to the green ‘on’ position. This will enable auto update for all apps on your device.

Another way to enable auto update for specific apps is to go to the App Store, find the app you want to update, and tap on the Update button next to the app icon. This will only update that one app, rather than all apps on your device.

You can also enable auto update for specific apps by opening the Settings app on your device, tapping on iTunes & App Store, and then enabling the switch next to Updates under Automatic Downloads. This will allow updates only for those apps that have this setting turned on.

Enabling auto update for iPhone apps is a good way to make sure you always have the latest versions of your favorite apps.

Reset All iPhone Settings

Invalid options or settings that are conflicting with the default system functions can destabilize the iPhone platform. For example, if you have customized your phone’s settings to require a password to unlock it, but then you forget that password, you will not be able to access your phone.

Likewise, if you have changed your phone’s background to a live photo of a busy city street, but then you’re stuck in a meeting and can’t hear it ringing, you might not be able to find it in time. In both of these cases, the customizations you made to your phone caused problems because they conflicted with the default system functions.

With automatic updates, sometimes settings are overridden which can lead to conflicts and adverse symptoms. In order to avoid update-related issues, it is important to carefully review the changes that will be made before proceeding with the installation.

How to reset all settings on an iPhone:

There are two ways to reset all settings on your iPhone. The first way is to do it through the Settings app, and the second way is to use iTunes.

If you want to reset all settings through the Settings app, go to Settings > General > Reset and tap on “Reset All Settings”. This will reset all of your preferences and settings, including your network settings, home screen layout, keyboard dictionary, and more. Note that this will not erase any of your data or apps.

If you want to reset all settings using iTunes, connect your iPhone to your computer and open up iTunes. Select your iPhone from the list of devices, and then click on the “Restore” button. This will erase all of your data and settings from your iPhone and restore it to its factory default state.

Factory Reset/Restore Your iPhone

A factory reset, also known as a master reset, is a last resort option for resolving recurring symptoms on a device. This process clears all user data and settings, and restores the device to its original state. It can be helpful in resolving complex system errors and malwares, but should only be used as a last resort.

This process can be useful in cases where the device is not working properly. In your case, your iPhone randomly restarting, or when the user wants to start over with a fresh slate.

However, it is important to note that resetting will erase all data from the internal memory, including contacts, downloads, customizations, and personal information.

Therefore, it is important to back up any important data before performing a reset.

After you have successfully backed up all your important data, you can proceed further with the factory reset.

To factory reset an iPhone, go to Settings > General > Reset > Erase All Content and Settings.

Again, note that this will erase all of your data and content including photos, videos, contacts, apps, and more. If you want to back up your data before resetting your iPhone, use iCloud or iTunes to backup your data.

Use iTunes For Factory Reset

You can use either a Mac or Windows computer to factory reset your iPhone. As long as it has the latest version of iTunes installed and is connected to the Internet, you should be good to go.

To erase and restore your iPhone to its factory defaults on a computer using iTunes:

1. Connect your iPhone to your computer using the USB cable.

2. Launch iTunes.

3. In the iTunes sidebar, click on your iPhone’s name.

4. Click on the “Summary” tab.

5. Click on the “Restore iPhone” button.

6. A dialog box will appear asking if you want to back up your iPhone before restoring it. Click on the “Back Up” button if you want to back up your iPhone data or click on the “Don’t Back Up” button if you don’t want to back up your iPhone data.

7. The restore process will begin and will take a few minutes to complete. When it’s done, your iPhone will restart and will be in its factory default state

Is Your iPhone Still Randomly Restarting?

There is one last good option for preventing your iPhone from the random restarts you’re currently experiencing. It’s called DFU mode restore.

A DFU mode restore is the deepest type of iOS restore you can do to fix or repair a corrupted operating system of your iPhone. DFU mode stands for Device Firmware Update mode and it allows you to update the firmware on your iPhone.

How to Enter DFU Mode

To use dfu mode to restart an iPhone, you will need to connect your iPhone to your computer and open iTunes. Once your phone is connected, hold down the home button and the power button at the same time until the phone turns off.

Once it is off, release the buttons and hold down the home button. After a few seconds, you will see a message on your computer that says “DFU mode.” At this point, you can release the button and restore your iPhone through iTunes.

Upgrade Your iPhone

When it comes to upgrading your iPhone, there are a few things to consider. One of the most important factors is whether or not your current iPhone is old. If it is, an upgrade may be in order, as older iPhones tend to have shorter lifespans.

Additionally, if you’re experiencing problems with your current iPhone, an upgrade may provide a solution.


Hardware damage can be difficult to diagnose and can sometimes be hard to repair. If your iPhone is still turning off randomly after performing the previous procedures, then it is likely that there is hardware damage present and you will need to take it to a repair shop for further evaluation.

Physical or hardware damage can often be the cause of an iPhone that isn’t charging properly. A bad battery or other flawed power components can be the issue, and in these cases, service or iPhone repair is needed.

You can take it to an Apple-authorized service center for assessment and, if necessary, repairs. The technicians at these centers will be able to help you with any damage your device may have sustained and get it working like new again.

Some of the most common problems that are fixed at these centers include a faulty screen, water damage, and battery replacement.
