Not every iPhone update is a winner. Sometimes apps don’t work correctly, the battery life takes or a whole host of other issues might arise. Thankfully, you can retry the installation of an update as many times as you want, providing you’re willing to spend the time required to do so.
This week, USA Today received a question from a distressed iPhone user who started running into issues after updating to iOS 9.2.1. Many iPhone 5s users have run into problems with the latest update, so if you happen to be (or know) one of them, here’s what you need to do to solve them:
Open up iTunes and restore your device to factory settings.
Here’s how you can do that without losing everything on your iPhone:
- Plug your iPhone into your Mac or PC
- Open iTunes and select your device from the menu bar at the top of the app
- Select the Summary tab under Settings
- Under Backups, click the bubble labeled This computer and the box that says Encrypt iPhone backup
- Click Back Up Now
At this point, you’ll have to set a password for the encrypted backup. Pick something you can remember (but OS X will offer to save the password for you if necessary). Once the backup is complete, there’s just one more step:
- Click Restore iPhone at the top of the Summary tab
This will install a fresh copy of the latest iOS update on your phone while simultaneously restoring all of the apps and data that were on your phone before you started the process. This isn’t guaranteed to solve all your issues, but there’s a good chance that a clean start could speed up your iPhone.
At least for a little while.
