Troubleshooting battery draining issue on an iPhone 11 Pro

The following procedures will help eliminate common software-related factors that can trigger rapid battery draining problem on an iPhone. Among the usual triggers to eliminate are rogue apps, invalid settings, bad updates, and corrupted system files. Unless you already have figured out the underlying cause, there is no other way but to go through a trial-and-error process. Just try these methods before opting for service.


First solution: Force restart your iPhone 11 Pro.

Rogue apps that caused rapid battery draining issue on the phone can all be stopped by performing a force restart on your iphone 11. A force restart is simulated battery removal process that is used to end all running apps and system processes including those that have been corrupted and trigger system problems like battery drain. Just follow these steps, to force restart your iPhone 11 Pro:

  1. Quickly press then release the Volume Up key.
  2. Quickly press then release the Volume Down key.
  3. Press and hold the Side button for about 10 seconds then release when you see the Apple logo.

Allow your phone to finish rebooting and then use it as you normally do to test how long the battery could last. 


Second solution: Update third-party apps.

Installing pending app updates can also help fix the problem if third-party apps are the main trigger. Apps that you’ve downloaded and installed on your phone also need to be updated regularly for them to remain optimized, bug-free and stable. If you haven’t configured these apps to auto-update, then you will need to update them manually. Here’s how it’s done:

  1. From the Home screen, tap on the App Store icon to open the application.
  2. Tap on Today tab at the bottom. 
  3. Then tap on the user profile icon (Apple ID header) on the top right corner of the screen. You should see the account details showing up on the display. 
  4. Scroll down to the Available Updates section. 
  5. Tap on Update<span style=”font-weight: 400;”> next to the name of the app to install individual app updates.
  6. If multiple app updates are available, tap on Update All to update all apps at once.

This process is only applicable if your iPhone has internet access and sufficient battery life to complete the update installation. To ensure no possible power interruptions during the update, plug your iPhone into its charger and charge it while updating. 


Third solution: Install new firmware update for your iPhone.

Another update that you shouldn’t fail to implement is the periodic firmware update or iOS update released by Apple. These updates not only offer new features but also embed some critical patches to get rid of widespread system errors and address existing problems plaguing iOS devices. If the battery draining issue on your iPhone is inflicted by some system bugs or malicious software, then installing the latest iOS version available can help. Here’s what you should do then:

  1. Tap Settings from the Home screen.
  2. Select General.
  3. Tap Software Update.

A notification containing the system details and requirements will show up if a new iOS version is up for grabs. Read and review the information then back up your iPhone data before downloading and installing the update file.

Reboot the phone when the update is completely installed to ensure that all new system changes and bug fixes are properly implemented.


Fourth solution: Remove suspicious bad apps to fix battery draining issue on your iPhone 11 Pro.

If your iPhone’s battery started to drain so rapidly after installing an app or content, there’s a better chance that the recently installed app is the culprit. To rule this out, delete the suspicious app from your phone and see if that solves the problem. Just follow these steps to delete the app from your iPhone 11 Pro:

  1. Get to your iPhone’s Home screen to get started.
  2. Scroll to and find the app that you’d like to delete or uninstall from your iPhone. 
  3. Tap and hold on the app icon for a few seconds. Keep holding the app icon when the pop-up menu appears and then release when the app icon starts to jiggle.
  4. Tap Delete from the warning message. 
  5. Follow the same steps to delete other apps that you’d like to uninstall.
  6. Finally, tap Done on the top-right corner of the screen once you’re done deleting apps.

If the battery drain stops after removing the app, then you’ve successfully eliminated the main culprit and thus, the problem is solved. Otherwise, consider trying other advanced solutions.


Fifth solution: Reset all settings on your iPhone.

As mentioned earlier, system settings that are not properly configured can also cause battery issues to occur, especially if those settings inflicted some sort of conflicts to your phone’s power system or battery system. To rule this out, resetting all settings on the phone can help. This reset erases all your system preferences including your customized options but doesn’t delete any saved information on the internal memory. Here’s how it’s done:

  1. From the Home screen, tap on Settings.
  2. Select General.
  3. Scroll down and tap on Reset.
  4. Tap Reset all settings from the given options.
  5. Enter your passcode if prompted to continue.
  6. Confirm action by tapping the option to reset system settings on your iPhone.

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


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

A factory reset or master reset can be considered among the last options if the battery draining problem continues after performing all the above procedures. 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 due to 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 iTunes on your computer, if you haven’t already.
  2. Connect your iPhone to the computer with the USB cable or Lightning cable that came with it.
  3. Wait for iTunes to recognize your device and when it does, you should see your iPhone’s icon in iTunes.
  4. Click to select your iPhone 11 Pro when it appears in iTunes.
  5. Then navigate to the Summary section.
  6. Click on the Restore [iPhone] button.
  7. If prompted, click on the Restore button again to confirm.

In the case where the battery problem instigated after installing a new iOS version to your iPhone, restoring in recovery mode can be a better option. Here’s how it’s done:

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

Follow the rest of the commands 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 having the same battery draining issue on your iPhone 11 Pro?

At this point, you may consider taking your iPhone to the nearest Apple service center in your place for hardware assessment. Even if what you’ve got is a new devices, 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.
