Battery draining problems in mobile devices aren’t always due to a bad battery. In fact, most cases of battery draining are attributed to software issues on the affected device. The usual triggers are faulty updates. In iOS devices, battery draining issues usually manifest among other post-update problems. And for some reason, it still emerges among the commonly raised issues encountered by iphone 11 owners who first updated to iOS 13.2.3. If by any chance you would end up facing the same dilemma after installing the latest iOS update on your iPhone, I’ve laid out a few potential solutions for you to try on. Feel free to refer to this simple guide whenever you need some help fixing your iPhone 11 battery that drains so quickly from an update.

Troubleshooting an iPhone 11 battery drains so quickly after installing the recent iOS update

Battery draining issues that are attributed to some system flaws, particularly post-update bugs are possible to fix at home. Feel free to refer to this troubleshooting guide.


First solution: Reboot your iPhone.

Device issues that suddenly occur from an update are often transpiring as minor system flaws that are usually remedied by a restart. Hence, performing a soft reset or force restart should be considered among the first potential solutions you should try on. Various types of software issues can be resolved by rebooting your iPhone. If your iPhone is still able to respond properly despite enduring rapid power drain, follow these steps to apply a soft reset:

  1. Simultaneously press and hold the Side and Volume Up buttons for a few seconds.
  2. Release both buttons when the Slide to Power off bar appears.
  3. Swipe or drag the bar to turn your device off.
  4. After about 30 seconds, press and hold the Side button and then release when the Apple logo appears.

If your iPhone isn’t able to respond, performing a force restart would be necessary. A force restart is a simulated battery removal procedure that is used to reboot an unresponsive iPhone. Similar to a soft reset, a force restart can also fix various types of system errors including post-update battery draining symptoms. Here’s how it’s done:

  1. Quickly press and then release the Volume Up key.
  2. Quickly press and 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.

Both these methods don’t affect the internal data, thus you won’t lose any personal information from your iPhone storage.

Second solution: Update your apps.

Installing app updates on your iPhone can also be the key to resolving the issue if rogue apps are the main triggers. Apps that are prone to acting up from an update and caused massive power consumption are usually those that aren’t up to date. If your iPhone has internet access and sufficient storage space to allocate new update files, plug it into the charger then follow these steps to check for and install pending app updates while your iPhone is charging:

  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. 
  4. Scroll down to the Available Updates section. 
  5. To update individual apps, tap the Update button next to the name of each app.
  6. If multiple app updates are available, tap on Update All to update all apps at once.

Wait until all apps are finished updating and then give your iPhone another restart to apply the recent software changes

Third solution: Reset all settings to fix your iPhone 11 battery that drains so quickly.

Some updates can override your settings automatically. If any of these overrides caused conflicts to your existing system preferences, problems and system errors could arise. And this is when resetting all settings is needed. This will erase all your system settings including customized options and then restores the default values. Follow these steps if you wish to give this reset a shot in resolving battery draining issue on your device:

  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 all settings on your device.

After the reset, all default system settings are restored. Don’t forget to re-enable individual features, especially those that are disabled by default. 

Adjusting some settings on your iPhone like lowering the screen brightness and disabling unused location-enabled services can also help slow down power consumption and thereby extends the battery life.


Fourth solution: Erase your iPhone and restore factory default settings.

This reset is usually deemed among the last options to deal with recurring symptoms. Your iPhone will likely end up enduring the same problem if complex system flaws are the underlying cause. To address these complex system errors, wiping your iPhone can help. Just don’t forget to back up all critical data from your iPhone storage, otherwise you’ll lose them permanently. You can back up your iPhone files to iCloud or iTunes as you would prefer. Once you’ve secured the backup, follow these steps to proceed with a factory reset on your iPhone 11:

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

Fifth solution: Restore your iPhone from an iOS backup.

Software-related issues that could not be resolved by a factory reset are usually dealt with a system restore. If you wish to continue troubleshooting your iPhone, performing a recovery mode restore can be considered as the next possible solution you can try on. To get started, you will need to secure a computer that has the latest version of iTunes app installed. Once you have the equipment ready, follow these steps to put your iPhone 11 in recovery mode and then restore from an iOS backup through iTunes:

  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 app 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.
  6. Shortly after you see the Connect to iTunes screen, you will be prompted with the next instructions via message prompts. 
  7. If prompted to Update or Restore your iPhone in iTunes, select Restore to erase your device and restore it from a recent iOS backup saved on your computer drive via iTunes. 

Refer to the next onscreen prompts to finish restoring your iPhone in iTunes. When the system is completely restored, you can disconnect your iPhone from the computer.
