This article helps troubleshoot your Apple iPhone 5c slowing, freezing, or turning off unexpectedly.

You may have performance issues if your Apple iPhone 5c:

  • Performs slowly
  • Freezes
  • Turns off or unexpectedly restarts
  • Displays error messages
  • Is unable to install or update applications

Try each of these steps to see if it helps improve your phone's performance.

  1. Perform a soft reset.

    A soft reset restarts your phone and does not erase any of your content or data.

    1. Press and hold the Power key and Home key.
    2. From the home screen, press and hold the Power key and the Home key.
    3. Release the Power key and the Home key when the Apple logo appears.
    4. Your Apple iPhone restarts.
  2. Determine if your phone has low memory.

    1. From the home screen, tap Settings.
    2. Scroll to and tap General.
    3. Tap Usage.
    4. If your phone has low memory, troubleshoot low memory issues.
  3. Close background applications.

    Some apps continue to run in the background after you exit them. Sprint recommends that you close background applications when you're not using them.

  4. Verify that your Apple iPhone 5c is running the most recent software.

    There may be a software update that improves battery life on your phone. Check for software updates.
