Question: iOS 11.1.1 update deteriorates battery life and automatic quits applications.

this is some thing which everyone should be worried about. I never expected some upgrade to deteriorate the ongoing performance of a device.


My iPad is not even one year old, and the latest release(11.1.1) quits apps, installed from App Store. battery performance should increase rather than decrease.


I have read some people also complaining about the same, also the new update is for the latest iOS device. My device is not even a year old for the matter.


its high time apple when you need to think about retaining the old customers rather than focusing only on new sales.


I want my device to work the way it did before the latest update.

Hello varmat,
If the steps in the above article didn't help, you may want to back up your iPhone and then reinstall the latest update using the steps below.

If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support

Put your device in recovery mode and set it up again

  1. Make sure that you're using the latest version of iTunes.
  2. If iTunes is already open, close it. Connect your device to your computer and open iTunes. If you don't have a computer, borrow one from a friend or go to an Apple Retail Store or Apple Authorized Service Provider for help.
  3. While your device is connected, force restart it with these steps:
    • On an iPhone X, iPhone 8, or iPhone 8 Plus: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Then, press and hold the Side button until you see the recovery-mode screen.
    • On an iPhone 7 or iPhone 7 Plus: Press and hold the Side and Volume Down buttons at the same time. Keep holding them until you see the recovery-mode screen.
    • On an iPhone 6s and earlier, iPad, or iPod touch: Press and hold both the Home and the Top (or Side) buttons at the same time. Keep holding them until you see the recovery-mode screen.

  4. When you see the option to Restore or Update, choose Update. iTunes will try to reinstall iOS without erasing your data. Wait while iTunes downloads the software for your device. If the download takes more than 15 minutes and your device exits recovery mode, let the download finish, then repeat these steps.
