How to restore iPhone from backup, and when you can

How to restore iPhone from backup has a precondition that reorders everything else, and Apple states it in the first step rather than in a footnote.

“Turn on your device. You should see a Hello Screen. If you already set up your device, you need to erase all of its content before you can use these steps to restore from your backup.”

One sentence, and it reorganises the whole question. A restore is something that happens during setup, not something you do to a phone you are already using. There is no menu on a working iPhone that pours a backup back into it. If the phone in your hand is set up, the honest sequence is: erase it, then restore during the setup that follows — which is a far larger commitment than the word “restore” suggests, and worth knowing before you start rather than halfway through.

With that established, the rest is a choice between two routes, and the choice is mostly decided by where the backup already is. An iCloud backup restores over Wi-Fi during setup; a computer backup restores over a cable. Neither is better in the abstract, and Apple gives the same instruction for choosing between individual backups on both: look at the date.

From an iCloud backup

during setup · over Wi-Fi
  1. At the Hello Screen, follow setup to the Transfer Your Apps & Data screen, then tap From iCloud Backup.
  2. Sign in to your Apple Account.
  3. “Choose a backup. Look at the date and size of each and pick the most relevant.”
  4. Stay on Wi-Fi and wait for the progress bar.

From a backup on a computer

over a cable
  1. Open Finder, or the Apple Devices app on Windows, or iTunes on Windows without it — or on macOS Mojave and earlier.
  2. Connect by USB and answer any passcode or Trust This Computer prompt.
  3. Select the device, then Restore Backup, and pick by date.
  4. Click Restore. “If asked, enter the password for your encrypted backup.”

On the iCloud side there is one extra instruction worth following literally. Apple says to look at “the date and size of each” — size, not just date. A backup that is markedly smaller than its neighbours is telling you something about what was included when it ran, and the moment to notice that is before you commit to it rather than after.

“If you’ve purchased iTunes or App Store content using multiple accounts, you’ll be asked to sign in to each account… Until you sign in to your Apple Account, you will not be able to use the apps.”

This is the part that surprises people on the far side of a restore. The apps are back on the home screen and they will not open. Their icons are placeholders until the account that bought them has been signed into, and if purchases were spread across more than one Apple Account over the years, that is more than one sign-in. Apple does let you defer it — “you can tap Skip this Step and sign in later” — at the price of a phone full of apps that do nothing yet.

The restore finishes twice

The progress bar is the first ending. Apple describes the second one plainly.

What happens if you walk out of range. Nothing dramatic, and Apple says so: “If you disconnect from Wi-Fi too soon, the progress will pause until you reconnect.” It pauses rather than fails — which is reassuring, and also the reason a restore that appears to have stalled has usually just lost the network rather than broken. The same applies to the long background stage afterwards, which is why the advice there is about Wi-Fi and power rather than about waiting by the phone.

One more case Apple documents, because it catches people at exactly the wrong moment. After a repair, “when you get your iPhone or iPad back from an Apple Store or Apple Authorized Service Provider, keep in mind you might need to restore your device” — from an existing backup or by setting it up as new. Handing a phone in for service is one of the times a current backup is worth checking rather than assuming.

What this page will not do is tell you which backup to pick. Apple’s instruction is the date and the size, you are the only one who knows what happened between them, and a page that guessed would be guessing about your week rather than about the software.

It also will not promise that everything comes back. A restore returns what the backup contained, and what a backup contains is a separate question with its own answer — which is the first floor below.

Where to start

Three ways in. If the phone is already set up, read the box above first.

“The phone is already in use.”
Erase comes first — the precondition
“Which route, iCloud or cable?”
Wherever the backup is — the two routes
“It is done but the apps will not open.”
One sign-in per account — after it finishes

The precondition

A restore is a setup-time operation. A phone already in use has to be erased before it can accept one, which makes this a bigger decision than the word suggests.

The two routes

iCloud over Wi-Fi during setup, or a computer over a cable. Apple’s instruction for choosing between backups is the same on both: the date, and the size.

After it finishes

It finishes twice: a progress bar of minutes to an hour, then hours or days of background restoring. And the apps stay inert until the buying account signs in.

What this tower will not do

It will not tell you which backup to choose. Apple gives you the date and the size; the rest is knowledge of your own week that no page has.

It will not promise everything returns. A restore gives back what the backup held, and what a backup holds is a different question with its own floor.

And it will not recommend third-party software that claims to restore selectively from an iPhone backup. Apple documents two routes and this site has tested nothing else against a real backup, which is the only test worth anything here. What holds instead is simple: the requirement to erase a device that is already set up before restoring, the iCloud route through the Hello Screen and the Transfer Your Apps & Data screen to From iCloud Backup, the instruction to choose a backup by date and size, the multiple-account sign-in and the note that apps cannot be used until you sign in, the Skip this Step option, the Wi-Fi pause behaviour, the progress bar taking a few minutes to an hour, the background restore taking several hours or days with the advice to connect often to Wi-Fi and power, the computer route through Finder, the Apple Devices app or iTunes with Restore Backup and the encrypted backup password, the instruction to stay connected until the sync finishes, and the note about restoring after a service appointment are quoted from Apple’s support documentation listed below.
