Why is the iPhone so popular? With a variety of features, top-level hardware configurations, and easy-to-use software, it does a great job in many ways. However, if your iPhone turns off by itself, I believe your experience will be greatly reduced. Computer expert website ZDNet believes that the reason for iPhone keeps turning off is a strange error in iOS11, but not every user who uses iOS 11 will encounter it.
If your iPhone is not damaged by hardware, you can try some simple ways to fix the problem before making an appointment fix. Don’t worry, I will detail the specific steps of each method.
Running Out of The iPhone’s Battery
Restore iPhone with iTunes
Restore Ultimate Edition with iTunes – DFU Mode
Check Battery and Replacement (iOS 11.3 and Higher)
How Did You Fix It?
Running Out of The iPhone’s Battery
This method is very simple, you just need to let the iPhone keeps shutting off until it runs out of power, forcing it to stop repeating. It takes some time, during which you can take a nap or go out for a walk until you see the iPhone is off. Here’s what you need to do:
Step 1. Leave the iPhone’s battery exhausted and do not charge it.
Step 2. When you see that it is off instead of repeatedly turning off, plug in the charger until it is fully charged.
Step 3. After charging is complete, turn on the phone to confirm if the problem has been solved.
Restore iPhone with iTunes
After trying to run out of iPhone power, iPhone keeps turning off and it’s time to use iTunes. iTunes is different from iCloud. Instead of performing the restore on the basis of the original, it will uninstall, reinstall and reload your data to solve iOS problems. This means it solves the problems that hard resets and iCloud restores cannot solve.
Step 1. Connect the iPhone to iTunes on your Mac or Windows PC using the original cable.
Step 2. After iTunes has successfully recognized the iPhone, click on the iPhone icon in the top left corner.
Step 3. If iTunes does not automatically start the backup process, click Backup Now to perform a manual backup.
Step 4. After the backup is complete, click the Restore iPhone button. Please wait a while, iTunes will uninstall and reinstall the iOS system.
Step 5. After the system is installed, the iPhone will start automatically. Please choose to restore from iTunes. Select the backup data you just backed up on iTunes and restore it to your iPhone.
After the backup recovery is complete, run the iPhone to check if the device is back to normal. If not, there are the following solutions, please do not give up.
Restore Ultimate Edition with iTunes – DFU Mode
After uninstalling and reinstalling iOS with iTunes, you still can’t solve the problem, then you may have to try the ultimate restore mode – DFU mode. It is more thorough than the previous method and can solve a large number of unknown iOS problems at the expense of all current data. However, if you have a backup, you can still retrieve them.
The following are detailed step-by-step instructions:
Step 1. Similarly, connect the iPhone to iTunes on your Mac or Windows PC using the original cable.
Step 2. Put your iPhone in DFU mode: Press and hold the power and home button for 8-10 seconds, keep pressing the home button while releasing the power button, and release the home button after receiving the prompt for iTunes detection success.
Step 3. DFU mode is different from recovery mode. It does not display any images or information on the iPhone screen. Only iTunes can detect iPhone in DFU mode. Click OK to proceed with the restore process.
Step 4. Choose to restore the iPhone and wait for the restore process to complete.
The above is the order of operation using DFU mode, if your iPhone has other unknown problems, it will be resolved.
Check Battery and Replacement (iOS 11.3 and Higher)
Why did my iPhone turn off? This is the final answer. iPhone running iOS 11.3 and above are given features designed to check battery health. It provides two key pieces of information: maximum charging capacity and battery strength affecting phone performance. To check the battery problem, follow these steps:
Step 1. Enter the settings and select the battery.
Step 2. Slide to the battery health function.
Step 3. The maximum capacity menu shows the battery overview. The higher the total charge capacity, the better. If the maximum capacity is at a very low state, this may be a problem with the battery.
Step 4. If other information is displayed in addition to the peak performance, this may also be a sign of a problem with the battery.
Step 5. In addition to being judged based on maximum capacity and peak performance, the battery health feature also indicates if the battery needs to be replaced.
According to the above inspection results, if your battery does need to be replaced, please go to the Apple Store for replacement instead of any other repair shop. This ensures that the replacement battery is the right model for your phone, allowing it to run smoothly and reducing the possibility of trouble in future use.
