First solution: Soft reset your iPhone 8 Plus.

Some apps can trigger certain apps or the phone system itself to act up and drain much power. Such problems are often due to minor glitches that can easily be resolved by a soft reset or restarting your iPhone. Hence it’s the first recommended solution to try. To soft reset your iPhone 8 Plus, follow these steps:

  1. Press and hold the Side/Power button until the Slide to Power Off command appears.
  2. Drag the slider to the right to turn your iPhone completely off.
  3. After 30 seconds, press and hold the Power button until the Apple logo appears and then release.

A soft reset does or restart does not affect any data saved in the internal memory of your iPhone. All your critical data and personal information should therefore stay intact. Temporary files that are stored as cache on the system folders will be cleared.

Second solution: Clear all background apps on your iPhone 8 Plus.

Background apps in iOS devices are cleared by forcibly closing them. Backgrounds apps not only used up memory space but also drains the battery as they’re still running in the background. The more background apps left opened, the busier the processor can become and more power is consumed. So here’s what you should do as remedy:

  1. Press the Home button twice quickly to open the Apps Switcher, containing a list of recently used apps on your device. These are in standby mode but still running in the background.
  2. To clear or force close individual apps, tap on an app preview.

Do the same to the rest of the background apps to clear them all.

Third solution: Disable, delete, or update your apps.

Clearing background apps may not be enough to get rid of an update bug. If your iPhone battery is still draining so fast after force closing background apps, check the battery usage to see which apps are consuming the most of your phone’s battery. If you see any unusual power consumption by an application, then you can either disable or delete the app.

Aside from deleting apps, installing pending updates from the App Store can also help. App updates also entrenched bug fixes to clear any errors inflicted by bugs and malware. To check for updates, simply follow these steps to get to the App Store:

  1. Tap the App Store icon from the Home screen. Doing so will open the App Store Main screen.
  2. Scroll to the bottom right of the App Store Main screen then tap the Updates icon. A list of apps with pending updates then populates the screen.
  3. Tap the Update button next to an app to install app update individually.
  4. If multiple app updates are available, tap the Update All button instead. Doing so will install all app updates simultaneously.

Reboot your iPhone when all updates are successfully installed. This will ensure all new app changes are properly implemented.

Fourth solution: Manage your iPhone settings.

Adjusting the display settings such as brightness level, use of themes, wallpapers, notifications, ringtones and the like can also help preserve battery life. If necessary, reduce the screen brightness to a comfortable level and select non-moving wallpapers and simple themes.

Alternatively, you can reset all settings on your iPhone 8 Plus to restore them to their default values then configure them individually. To do this, follow these steps:

  1. Open Settings from the Home screen.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Select the option to Reset all settings. This will reset system settings, restoring the defaults without affecting your iPhone data.
  5. Enter your device passcode, if prompted.
  6. Then tap the option to confirm settings reset.

When the system settings are reset to defaults, your iPhone will restart by itself. Wait for it to boot up completely then you can start enabling necessary features and options.

Fifth solution: Restore your iPhone 8 Plus in iTunes.

A recovery mode restore will erase all data from your device. Any complex errors the new iOS update might have caused will likely be obliterated and so your iPhone system should be working properly again. Should you wish to proceed, be sure to back up all your important files either to iCloud or iTunes. Then follow these steps when you’re all set to restore your iPhone 8 Plus in recovery using iTunes:

  1. Plug in your iPhone to your computer.
  2. Open iTunes on your computer then wait until your iPhone is recognized and connected.
  3. When your iPhone is connected, force restart it with these steps:
  • Press and quickly release the Volume Up button.
  • Then press and quickly release the Volume Down button.
  • Finally, press and hold the Side/Power button until the Recovery Mode screen or Connect to iTunes screen appears.
  • When prompted with the option to Update or Restore, select Restore.
  • Wait until iTunes will finish downloading software for your device. Your iPhone will exit recovery mode if the download takes more than 15 minutes. If that happens, let the download finish then go back to the previous steps to enter recovery mode again.
  1. Wait until the restore process is finished then you can proceed with the initial setup process to use your iPhone again.

If your iPhone 8 Plus battery is still draining so fast after a recovery mode restore, then you may have to consider performing a DFU mode restore. This will put your iPhone into a state where it’s still able to communicate with iTunes on a Windows or Mac computer without activating the boot loader or iOS. Thus, your device can still be restored even if the software has become totally corrupted.

  1. To restore your iPhone 8 Plus in DFU mode, quickly press and release the Volume Up button, then quickly press and release the Volume Down button.  Then press and hold the Side/Power button until the screen becomes completely black.
  2. As soon as the screen goes black, press and hold the Volume Down button while continuing to hold down the Side/Power button.
  3. After 5 seconds, let go of the Side/Power button but keep holding the Volume Down button until your iPhone appears in iTunes.
  4. As soon as your device shows up in iTunes, let go of the Volume Down button.

At this point, your iPhone is already in DFU mode, so you can proceed with an iOS restore using iTunes.

Other options

You can take your iPhone 8 Plus to the nearest Apple service center in your place and have it diagnosed by an Apple technician for any indications of hardware damage. To make sure the problem isn’t due to a bad battery, let the technician check on the battery condition as well. Some cases of rapid draining are directly associated with a bad battery, so that’s another factor to look into as well. You can have the battery replaced, if needed.
