Solution #2: Update third-party apps.

Installing pending app updates can also help fix iOS 15 battery drain problem if third-party apps are the main trigger. Apps that you’ve downloaded and installed on your iPhone also need to be updated on a regular basis for them to remain optimized, bug-free and stable. If you haven’t enabled the auto-update feature on your iPhone, then you will need to update them manually. Simply follow these steps:

  1. Start the **App Store** app on your iPhone.
  2. Tap on **Today** tab located at the bottom of the screen. 
  3. Tap on your **profile** icon (Apple ID header) on the top right corner of the display. You will see the account details showing up on the screen.

    1. This process is only applicable if your iPhone is connected to the internet and has enough battery life to complete the update installation. To avoid possible power interruptions during the update, plug your iPhone to a power outlet and charge it while updating. 

      Solution #3: Install iOS update

      Another update that you should keep in mind to implement is the periodic firmware update or iOS update released by Apple. These updates not only deliver new features but also includes some dedicated patches to get rid of widespread system errors and resolve existing glitches plaguing iOS devices. If the iOS 15 battery drain problem on your iPhone is caused by some system bugs or malicious software, simply install the latest version of iOS 14. Please follow these steps:

      2. Go to **‌**General.
      3. Tap **Software Update**.

      You will see a notification that contains system details and requirements if a new iOS version is available. Before downloading the update, be sure to read and review the release notes. Also, make sure to back up your iPhone data for safekeeping.

      Solution #5: Reset all settings on your iPhone.

      As we’ve already mentioned, system settings that are not properly configured can also cause battery drain problems to occur, especially if those settings inflicted some sort of conflicts to your iPhone’s power system or battery system. You can rule this out by resetting all settings on your iPhone. This reset removes all your system preferences including your customized options but does not delete any of your data. Please follow these steps:

      1. Start the **settings** app on your iPhone.
      2. Go to **‌**General.

      After the reset, your iPhone reboots on its own and then loads up the default values and options. To use necessary features, you will need to re-enable them one at a time.

      Last resort: Erase your iPhone and restore its factory default settings.

      If you are still experiencing iOS 15 battery drain problems, you may want to factory reset your iPhone. What you’re dealing with could be a complex system error that requires a full system wipe out to be obliterated. In this case, I recommended the use of iTunes to manually
      erase your iPhone on a computer. This way you’ll be safe from unexpected shutdown which could be caused by battery drain. Just be sure to use the original USB cable or Lightning cable, so you won’t have any trouble connecting your iPhone to the computer. Also don’t forget to back up all your important files beforehand to prevent losing them permanently. Once you’ve got everything set, follow these steps to start wiping your iPhone data.

      1. Open the **iTunes** app on your computer, if you haven’t already.
      2. Build a connection between your iPhone and computer with the original USB cable or Lightning cable.
      3. Wait for iTunes to recognize your device and when it does, an iPhone’s icon will appear in iTunes.
      4. Click to select your iPhone when it appears in iTunes.
      5. Now, navigate to the **Summary** section.
      6. Click on the Restore [iPhone] button.
      7. If asked, click on the **Restore** button again to confirm your decision.

      In the case where the battery problem started after installing a new iOS version to your iPhone, restoring in recovery mode can be a better option. Follow these steps to restart your iPhone in recovery mode:

      1. Build a connection between your iPhone and computer using the original USB cable or Lightning cable that came with it.
      2. Launch iTunes on your Windows or Finder on your Mac running
        macOS Catalina.
      3. While your iPhone is connected, quickly press and let go the Volume Up button. 
      4. Next, quickly press and let go the Volume Down button.
      5. Next, press and hold the Side button until you see the Connect to iTunes or recovery mode screen.
      6. Do not release the button if the Apple logo appears as you’ll need to boot your phone in recovery mode.

      Follow the on-screen prompts to restore and fresh install the firmware on your iPhone through iTunes. You can also restore your iPhone from a previous backup saved on your computer through iTunes.

      Still experiencing the same iOS 15 battery drain issue on iPhone?

      At this point, you may want to take your iPhone to the nearest Apple Store to be serviced, . Even if your iPhone is new, it’s still possible for it to acquire some sort of damage on any relevant components, likely from factory defects. You can also escalate the problem straight to your iPhone provider in case you’d like to ask for a new unit replacement. This is a must-do if your iPhone is still covered by warranty.
