Performance issues like frequent freezes and lags are more common than other problems, but they’re not really that difficult to fix. Most of the time, you can fix them by simply doing the most basic troubleshooting procedures. If you’re one of the users with this problem, here’s what you should do: 

First solution: Close all apps running in the background 

There are times when apps can cause your iPhone to freeze, especially if there are a lot of them left running in the background. Thus, the first thing you need to do is to close them all and see if that makes your device run smoother. Here’s how it’s done: 

  1. Swipe up from the bottom of the screen and stop at the middle. This will show you all the apps that are running in the background. 
  2. Swipe up on each app preview to close them. 

Once you’ve closed all the apps, try to see if your phone still freezes. 

Second solution: Force restart your iPhone

Closing background apps may not be enough. So if your iPhone 12 still freezes randomly after the first solution, then you should try refreshing your device’s memory, as well as reloading all apps and services. You can do both by doing the Forced Restart. Here’s how: 

  1. Quickly press and release the volume up button and then the volume down button. 
  2. Immediately after that, press and hold the Power key for 10 seconds. This will force your iPhone to shut down and power back up. 
  3. Once the Apple logo shows on the screen, release the power key and allow your device to complete the boot process. 

After the restart, try to see if your iPhone still freezes. 

Third solution: Check the storage

Another thing you need to do should the problem continue even after doing the forced restart, is to check the storage. As you know, apps and services take up storage when used. If there’s not enough storage on your iPhone, then that might be the reason why it freezes randomly. 

  1. To check the storage, launch the Settings app. 
  2. Find and tap General. 
  3. Tap iPhone storage. 
  4. You may delete some of your apps, files or data if necessary, especially if you only have about a couple of gigabytes left. 

After managing your iPhone’s storage, move on to the next solution. 

Fourth solution: Check for new updates

There is also a possibility that this problem is widespread, and if that’s the case, then Apple should roll out an update that will patch it. So what you have to do next is to check if there’s an available update. 

  1. To do so, launch the Settings app. 
  2. Find and tap General. 
  3. Tap Software update. 
  4. If there’s an update available, download and install it. 

After updating your iPhone, try to see if it still freezes randomly. 

Fifth solution: Reset all settings on your device

After doing the previous solutions and your iPhone 12 still freezes frequently, then it’s time to bring all of its settings back to their default values. It’s possible that such a problem is caused by some inappropriate settings, and doing this procedure will rectify them. You don’t have to worry as none of your files and data will be deleted. Here’s how it’s done: 

  1. From the Home screen, tap Settings. 
  2. Find and tap General. 
  3. Scroll down to the bottom of the screen, and then touch Reset. 
  4. Touch Reset All Settings. 
  5. If prompted, enter your security lock. 
  6. Tap Reset All Settings at the bottom of the screen, and then tap Reset All Settings again to confirm. 

After doing this, continue using your iPhone to see if the problem is fixed. 

Sixth solution: Factory reset your iPhone

Lastly, if your iPhone 12 continues to freeze randomly even after the previous solutions, then you have no other choice but to reset it. A factory reset will fix this problem, however, make sure to create a backup of your important files and data, as they will be deleted during the process. 

Once you’re ready, follow these steps to reset your iPhone: 

  1. From the Home screen, tap Settings. 
  2. Find and tap General. 
  3. Scroll down to the bottom of the screen, and then touch Reset. 
  4. Tap Erase All Contents and Settings. 
  5. Tap Erase Now. 
  6. If prompted, enter your security lock. 
  7. Tap Erase iPhone at the bottom of the screen.  
  8. Tap Erase iPhone again to proceed.  
  9. Now enter your Apple ID password, and then tap Erase to proceed with the reset. 
  10. Wait until your iPhone has finished the reset, and then set it up as a new device. 

Your iPhone 12 should work properly after this, and it should be running smoothly now.
