Did you get a new iPhone to replace an old or broken one and you tried restoring the new iPhone from backup, but it's taking too long? This can often happen when you have lots of data on your backup from your old phone. Sometimes the restoring process might even seem fairly short at first (maybe only a few hours), then it will steadily increase while it's restoring, instead of decreasing like it should!

If your estimated restoring time is 20 hours or more, you might be wondering if something is wrong. This can be especially bewildering if you're using your lightning cable (which is supposed to be fast) instead of your local Wi-Fi network.

So, why is this happening and how do you fix it?

Reasons Why Restoring iPhone from Backup Takes Too Long

There are many reasons why restoring your iPhone from backup may be taking too long:

1. It could be that you don't have the latest version of iTunes on your computer, and this could be causing problems.

2. You can't restore an iPhone backup that was made with an newer version of iOS (iOS 15, for instance) to a phone that uses an older version (for instance, iOS 9).

3. You may not have enough storage space on the new phone to take the backup. Make sure that it does.

4. Sometimes the issue is a bug or there are unknown problems that are hard to identify.
