"My iPhone has been having issues with battery drain when Wi-Fi and cellular data is selected even when asleep. It can be at 100% only to go down to 10% within the next 4 hours. I think the best course of action, in this case, is to do a restore but I am worried about all the data on the iPhone including all my apps, movies, notes etc. What actually gets restored when I restore the iPhone? What data will be lost? Can I do a backup of all the data on the device before restore my phone?"

What Happens When You Restore an iPhone

A restore is a solution that can be used to fix a lot of issues with your iPhone including a battery drain issue. If you choose to restore your iPhone to its factory settings, you will lose all your data and settings on the phone like contacts, messages and all the other data. You iPhone will be set as a new iPhone after the restore. It is same to all the iOS versions, no matter an iOS 7 or iOS 12.

If you choose to restore your device from a backup you created, everything on your iPhone will be switched to the data and settings in your backup file when the restore is finished. So before restoring a device, you should create a backup for the iPhone. Just connect it to iTunes and then click "Back Up Now" like the following picture shows.

How to Restore Your iPhone via iTunes/iCloud/3rd-party Tool

You can choose to either restore the device from an iTunes or iCloud backup depending on where you backed up your device. Here's how to do it.

1. Restore from an iCloud Backup Entirely

  • Step 1: To begin, you have to erase all the data and settings on your device to get to the setup page (Hello Screen). To do this go to Settings > General > Reset > Erase All Content and Settings.
  • Step 2: The phone will give you option to "Backup Then Erase". Just tap on it and follow the prompts on the setup screen until you get to the “Apps & Data” screen where you should choose "Restore from iCloud Backup."
  • Step 3: Sign in to iCloud and then select the most relevant backup. Stay connected to a Wi-Fi network until the restore process is complete.

Disadvantages of the iTunes or iCloud Restore

The biggest disadvantage of restoring your device via iTunes or iCloud is the loss of new data on the device. If for example, you have a few new text messages that you received after you had already created the backup on iTunes or iCloud, they will not be in the backup and hence will be lost when you restore your device from a backup. That's because both iTunes and iCloud backup restore process erase all the data on the device before restoring it.

You also can't choose the data to restore to your device. You can't even see what's on the individual backup file.
