You will encounter random restarts when your device runs low on storage. The problem might also be triggered due to system bugs. If the cause is not too complex, then it’s just minor and can easily be remedied by standard procedures. Otherwise, it requires solutions that are more advanced. Any device can face random restarts and Apple latest iPhone XS and XS Max are no exception. To give you some workarounds on how to deal with this problem, below are potential solutions you should try. Read on this post to know what to do if your new iPhone XS/XS Max suddenly reboots by itself without any reason.
Solution 1: Clear all background apps on your iPhone
Rogue apps in the background can be the main triggers of system instability. Although keeping apps running in the background will help in reloading or multitasking them faster, they can get corrupted at some point. In case this happens, other apps and the entire system of your phone could be adversely affected as well, and symptoms start to emerge. Thus, you should try clearing all background apps running on your iPhone XS/XS Max by following these steps:
- Swipe your finger up from the bottom of the screen and then pause.
- Swipe right or left to scroll through apps preview.
- Finally, swipe up on each app preview to close it.
If the problem only appeared after you installed a new app, then it is likely the trigger. In this case, you need to uninstall that suspected app and check if the problem is already fixed. If not, move to the next solutions.
Solution 2: Force restart your iPhone
A force restart is necessary when a phone gets stuck and the simple reboot could not help since the screen is already unresponsive. Similar to a reboot, a force restart can fix several problems caused by minor system errors and software-related issues. Cached files including corrupted temporary data will be cleared out during the process. Since the absence of the physical Home button, the way to perform a force restart on iPhone XS/XS Max is also different. Here is how to force restart an iPhone XS/XS Max:
- Press and quickly release the Volume Up button.
- Do the same with the Volume Down button.
- Finally, press firmly the Power button and then release when you see the Apple logo.
Wait until your phone completes booting up and you can then check if the problem is gone. Minor software issues will be eliminated by a force restart, but they still persist if the main trigger comes from more complex system errors.
Solution 3: Install pending updates for apps and iOS system
Bugs affecting system instability is often rectified just by an update. If rogue apps are the main cause, you should then update them to fix the problem. If there is a corrupted system or system data, updating your phone to the latest version can address the problem. You should first check for pending app updates and install them by following these steps:
- Open App Store, scroll down and tap on Updates section.
- Scroll through the list of apps with pending updates.
- Tap on Update button next to each one.
- Tap on Update All button if you want to install all app updates at once.
Once you complete installing pending app updates, you should then check for new iOS update to wirelessly download and install it
- To check for the latest iOS update, head over to Settings-> General-> Software Update.
If there is an update available, you will see a notification. Simply follow the rest of the onscreen instructions to install the update.
When the process is done, reboot your iPhone to apply the recent changes. After that, check if the problem is gone.
Solution 4: Reset and restore your iPhone.
A factory reset will wipe all the data, settings saved on your iPhone internal storage and install the latest iOS version on it. This is often the last resort to fix complex system errors that could not be solved by the prior methods. Before getting started, remember to back up all your important data to iCloud or iTunes. Once you are done, follow these steps below to restore your iPhone XS/XS Max to factory defaults:
- Open Settings from the Home screen.
- Tap on General > Reset.
- Select Erase all content and settings option.
- Enter your passcode when you are prompted to continue.
- Tap on the popup to confirm a system reset.
If the above could not be carried out, you need to restore your iPhone using iTunes on your computer to fix random restarts on your iPhone. Make sure your Mac/Windows has the latest version of iTunes installed. Once everything is all set, follow these steps to restore your iPhone XS/XS Max through iTunes:
- Launch iTunes on your computer.
- Plug your iPhone into the computer with a certificated Lightning cable.
- When you are prompted with Trust This Computer or enter passcode, simply follow the onscreen instructions.
- Click on your iPhone icon when it appears in iTunes.
- Switch to the Summary tab from the iTunes screen.
- Click on Restore [device] button.
- When you see a confirmation message, just click on Restore button to confirm the action. iTunes will start erasing your iPhone and then install the latest iOS version.
Your iPhone will restart during the process. Once done, you can proceed with the initial setup steps and set your iPhone as new.
Solution 5: Restore iPhone in recovery mode.
Major software errors including random restarts which could not be fixed by a factory reset might be solved by performing a recovery mode restore. It’s an advanced system restore with an unresponsive or stuck iPhone through iTunes. Similar to the factory reset, all your important will be lost. So if possible, back them up beforehand. Once you’re set, proceed with these steps below:
- Plug your iPhone into the computer using the Apple-supplied cable.
- After it’s connected, press and quickly release the Volume Up button.
- Do the same with the Volume Down button.
- Press Power button and continue to hold it as your phone restarts. DO NOT release the Power button when you see Apple logo since you are putting your iPhone into a recovery state.
- Release the Power button when the Connect to iTunes logo appears on the screen.
- On iTunes, you will see a message saying that your iPhone is in recovery mode and you are prompted to update or restore.
- Just click on Restore option to erase everything from your iPhone XS/XS Max and then restore the firmware through iTunes.
Wait until the process is done, disconnect your iPhone from the computer and check the result.
