The device will create room for additional content if you have less than 1 GB of storage on your iPhone.

Here’s how you can check your iPhone’s storage:

  2. Then, tap on iPhone Storage.
    General settings
    Go to iPhone Storage.

From here, you can view your iPhone’s storage and delete any unused apps by tapping on the app and then on ‘Delete App.’ You can also tap on ‘Offload App‘ to free up the storage used by the app without deleting the data.

4. Update Your iPhone Using a PC.

If your iPhone is completely stuck when you turn it on, the screen is frozen, and only the Apple logo appears on the screen, you need to update it using a PC. If this is the case with your iPhone, you cannot try any other method because the screen is unresponsive. Thus, using a PC is the only option that will help you.

Updating your device will make it run faster and more smoothly, as it will fix bugs and update security. It will also add more useful features to your iPhone, which may contribute to improved performance.

  1. Connect your device to a PC. If you are using a Mac with macOS Catalina, go to the Finder. For Macs with macOS Mojave or an earlier OS, go to iTunes. Follow the same steps on a Windows PC.
  2. Next, choose the device on your PC.
  • If you are using Finder (macOS Catalina or the latest OS), you will see your device name in the sidebar.
  • If you are using iTunes (macOS Mojave, previous operating systems, or a Windows PC), an iPhone icon will appear in the upper left corner.

As your device is now connected to your PC, here are the steps you need to follow:

  • On the iPhone 6s or previous versions, press and hold the home and side buttons/top buttons.
  • On the iPhone 7 and iPhone 7 Plus, press and hold the side button and volume down button.
  • On iPhone 8 or later versions, press the volume up button and release it immediately. After this, press the volume down button and release it quickly. Lastly, press the side button and hold it.

While you are holding the button, you will see that the recovery mode appears on your screen.

Next, you will receive a pop-up notification on your PC or Mac regarding restoration or update. At this point, you must select “Update.
6. Now, the PC will download the software for your iPhone. Nevertheless, if the process takes more than 15 to 18 minutes, you will need to repeat the aforementioned steps, as your iPhone will exit the recovery mode.

5. Reset Your iPhone.

If your iPhone continues to freeze after updating it, you may need to reset it, as there might be some files that are not compatible with your device. A reset will return your phone to its factory settings, effectively making it like new.
Also, it will solve any software-related or app-crashing issues. However, if you reset your iPhone, it will clear all the data stored in it. Therefore, you need to back up all your important data before a reset. Here is how you can reset your device:

  1. Go to Settings > General.
  2. Scroll down and tap on Transfer or Erase iPhone.
    Transfer or Reset iPhone settings
    Tap on Erase All Content and Settings
  3. Next, tap on Erase All Content and Settings.
  4. Hit the Continue button.
    Tap on Continue button
    Hit the Continue button
  5. Enter the password that you use to unlock your device.
  6. Choose Erase iPhone. With this, the process of erasing all your data will start.

When setting up your iPhone, you have to restore the data. However, if your iPhone starts to freeze again, reset it, but this time do not back up your data, as there might be some corrupt files causing the freezing issue. You can download the apps after a few days.

If you have tried all the methods and your iPhone still freezes and does not work properly, you need to call Apple support and ask them to resolve the issue or to replace your device if it is still under warranty.
