Troubleshoot charging issues on your Apple iPhone 4s

Last Updated: Nov 23, 2015

This article helps troubleshoot charging issues on your Apple iPhone 4s.

You may have charging issues if your Apple iPhone 4s:

  • Doesn't charge
  • Charges slowly

Try each of these steps if your phone has charging issues.

  1. Verify that your phone and charging port are not damaged.

    1. Carefully inspect your phone to be sure it's not overheating, swollen or damaged.
    2. Carefully inspect your phone's charging port and remove any debris.

    Caution: If your phone is damaged, do not complete the remaining steps in this guide. Please dial *2 on your phone or dial 855-639-4644 to reach Sprint Prepaid Customer Care.

  2. Verify that your Apple iPhone 4s can power on.

    1. Turn your phone on.
      • If your Apple iPhone 4s does not turn on, dial *2 on your phone or dial 855-639-4644 to reach Sprint Prepaid Customer Care.

  3. Verify that your charger is working.

    Connect your phone to your charger and see if the charging icon displays.

    Note: You risk severe damage to your phone if the charger isn't the same voltage, amps, and plug type as your original charger. You can purchase compatible chargers on <sprint.com.

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

    1. From the home screen, tap Settings.
    2. Scroll to and tap General.
    3. Tap Software Update.

    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. Release both keys when the screen goes black.
    3. Then press and hold the Power key until your Apple iPhone 4s restarts.
