One of the most annoying issues a device owner can face due to software and hardware issues is random restarts, or when your device just shuts down and then starts up on its own. Random restarts in older devices are frequently linked to memory issues and decreased performance.
It is more likely to be triggered by software-related factors, such as malware, software update bugs, and rogue apps, in new devices. Battery-draining symptoms can also be linked to random restarts.
In the worst scenarios, erratic restarts appeared as a direct sign of hardware damage, such as when your device sustained physical or liquid damage as a result of accidental drops or liquid exposure. Physical repair is required to address symptoms associated with hardware. However, in order to rule out software-related issues, performing some applicable troubleshooting techniques is highly recommended prior to rushing to a service center.
The iPhone’s self-disabling issue is similar to the one highlighted below, and potential solutions are highlighted below. Continue reading to find out what causes the iPhone to behave abnormally and how to restore normal operation.
Check to see if your smartphone is one of the ones we support for smartphone owners who came across our website while searching for a solution. If that’s the case, go to the device’s troubleshooting page, look for issues that are similar to yours, and feel free to use our solutions and workarounds. However, if you still require our assistance after that, please complete and submit our iPhone issues questionnaire.
The first option is: Get rid of bad apps
As previously stated, rogue apps frequently cause mobile devices to restart at random. Check your iPhone’s storage to see which apps are consuming a lot of power to rule this out. Update or delete the apps that are using the most battery power on your iPhone. So, the first thing you should do is:
- Tap Settings from the Home screen.
- Press Battery.
- Select the Show Activity option.
- Select “Show Detailed Usage” from the menu. Apps and services background and on-screen activity will be broken down.
- Tap Battery Usage to view a percentage breakdown of power consumption.
- Tap on “Last 24 Hours” to see more information about the power consumption in the last 24 hours.
- If not, tap 10 Days to see power consumption over time.
Find out which apps are using a lot of power in unusual ways over time because these apps often cause the battery to run out and shut down without warning. You have two options for dealing with these harmful apps: update them or remove them entirely. If an update is available, follow the steps listed below to update apps on your iPhone. If not, follow these steps to delete the application:
- Tap and hold on an app icon on the Home screen until the icons start to move.
- On the app, you want to delete, tap the X in the upper left corner.
- If prompted to confirm app deletion, tap Delete.
- To stop the apps from moving, tap the Home screen.
You can reinstall the app from the App Store if you still want to use it. To download and install the most recent version of the app, simply search for it.
Reboot your iPhone after updating or deleting and reinstalling bad apps to refresh the operating system and remove junk files from its memory cache. Move on to the next solution if the random restarts continue after this.
The second option is: Manage the space on your iPhone.
Random restarts can also be caused by memory-related issues like low storage. If you already have a lot of apps and saved content on your iPhone, it might be time to clear some space. Having said that, go to the storage on your iPhone and delete any apps, messages, or other files that you don’t use anymore.
- To accomplish this, navigate to the Settings->iPhone Storage menu and locate the app(s) you wish to delete.
- Open the Messages app and then delete any messages threads that are no longer necessary to delete old messages.
- You should also delete old and unused media files like photos and videos, in addition to messages.
The Third option is: If available, update iOS and applications.
If malicious apps are the primary cause, installing app updates may be able to resolve the issue. Most of the time, outdated apps are the ones most likely to become rogue. As a means of guaranteeing that their apps remain bug-free and optimized, app developers frequently release updates. You can manually check for and apply pending app updates on your iPhone using the following steps if you haven’t set your apps to automatically update:
- To launch the App Store, tap.
- Tap the Updates tab at the bottom of the App Store screen as you scroll down. After that, a list of apps that still need updates will appear.
- To begin updating, tap the Update button located next to the app’s name.
- Tap the Update All button on the upper-right side of the screen if multiple app updates are available.
If system bugs and malware are the underlying cause of the issue, installing the most recent iOS version for your iPhone is a possible solution in addition to updating apps. Settings are a quicker way to check for a new iOS update. Simply adhere to these steps:
- From the Home screen, tap Settings.
- Click General.
- Select Software upgrade.
If a new iOS version is available, an update notification will be displayed. Even though wirelessly downloading and installing an iOS update is an option, there is no guarantee that the update will be installed over the air because you don’t know when your iPhone will shut down and reboot on its own.
In this case, it’s best to update your iPhone through iTunes. Simply prepare a Windows or Mac computer, connect your iPhone using a Lightning cable or USB connector, launch iTunes, and wait for the iOS device to sync. Finally, to manually update your iPhone in iTunes, follow the on-screen instructions.
To avoid system conflicts, make sure to use the most recent iTunes version. Additionally, your computer will need to communicate and sync with Apple’s update server, so ensure that it has reliable Internet access.
Reboot your iPhone after you’ve finished updating it to make the most recent system changes take effect and fix any unforeseen app or software bugs.
