Restoring Iphone From Backup Time Estimate

Have you ever tried restoring your iPhone from a backup, only to get stuck at the “Estimating Time Remaining” screen? This frustrating error seems to freeze the restoration process indefinitely.

Don’t worry – you’re not alone. Many iPhone users have encountered this issue before. The good news is there are several effective solutions you can try to successfully restore your iPhone from a backup.

By the end, you’ll have the knowledge to troubleshoot and resolve the Estimating Time Remaining error when restoring your iPhone from a backup. Let’s get started!

What Does “Estimating Time Remaining” Mean?

The “Estimating Time Remaining” message appears when you are trying to restore your iPhone from an iCloud or iTunes backup.

During the restoration process, iOS needs to download your backup data, unpack it, and rewrite it to your iPhone’s storage.

The “Estimating Time Remaining” screen is meant to display a progress bar showing how long this process will take. However, sometimes this gets stuck due to issues interrupting the restoration.

When this message doesn’t go away and no progress bar is shown, your iPhone is essentially frozen. The restoration process cannot finish until the underlying problem is fixed.

Key Reasons for the “Estimating Time Remaining” Error

There are a few common culprits for the Estimating Time Remaining bug when restoring an iPhone backup:

1. Slow or Unstable Internet Connection

Restoring from a backup requires downloading data from iCloud or iTunes. A slow, unstable or intermittent internet connection can lead to errors or timeout issues.

This is especially true if you have a large backup (multiple GBs). It may take hours to complete on a slow connection. WiFi problems are a common cause.

2. Not Enough Storage Space on Your iPhone

Your iPhone needs enough free storage space to download the backup and unpack it during restoration.

For example, iOS 16 requires at least 1.5GB of available storage. If your iPhone is low on space, it may get stuck.

3. Outdated or Buggy iOS Version

Sometimes the Estimating Time Remaining bug is actually an iOS software bug. Apple usually fixes these in later iOS updates.

So if you’re trying to restore onto an older or buggy iOS version, you may encounter issues.

4. Corrupted Backup File

In rare cases, the backup file itself is corrupted or damaged in some way. This prevents a successful restoration since the data is compromised.

Deleting the backup and making a fresh one can resolve this issue.

5. Restoration Process Interrupted

Any interruption of the restoration process – a computer crash, power outage, cable disconnection etc. – can lead to errors.

Unexpectedly unplugging your iPhone before restoration completes often causes the Estimating Time Remaining bug.

Now that you know what’s behind this error, let’s go through the step-by-step solutions to fix it.

7 Solutions to Fix “Estimating Time Remaining” Error

Solution 1: Delete the iOS Update and Reinstall

If your iPhone is stuck while downloading the iOS update during restoration, try deleting the update file and reinstalling it:

Delete the Update and Reinstall It
  1. On your iPhone’s Home screen, tap Settings > General > iPhone Storage.
  2. Find the iOS update file (with the iOS version number). Tap on it.
  3. Tap “Delete Update” to remove it.
  4. Go back to Settings > General > Software Update and download the update again.

Deleting the corrupted or incomplete download forces it to freshly re-download, often fixing the issue.

Solution 2: Force Restart Your iPhone

If your iPhone is frozen on the Estimating Time Remaining screen, force restart it:

  • On Face ID iPhones X or later – Press and release Volume Up button. Press and release Volume Down button. Finally, press and hold Side button until you see the Apple logo.
  • On Touch ID iPhones 8 or earlier – Press and hold both the Home and Side buttons together until you see the Apple logo.

This hard resets your iPhone, interrupting the restoration process. When your iPhone reboots, you can try restoring again. Force restarting can jolt it out of being stuck.

Solution 3: Update Your iPhone to the Latest iOS Version

As mentioned before, the Estimating Time Remaining bug is sometimes caused by an iOS software bug.

Updating your iPhone to the latest iOS version (16.1 at time of writing) can fix underlying software issues:

  1. Tap Settings > General > Software Update and install any available updates.
  2. If your iPhone is still on an old iOS version, updating to the latest version will install newer bug fixes and improvements.
  3. After updating iOS, try restoring from your backup again.

Solution 4: Turn Off Find My iPhone Temporarily

Find My iPhone being enabled can sometimes interfere with the iPhone restoration process.

Temporarily turning it off may allow the restore to complete:

  1. Go to Settings > [your name] > Find My > Find My iPhone.
  2. Toggle OFF Find My iPhone.
  3. Try restoring from the backup again now.
  4. Once finished, you can turn Find My iPhone back on.

Solution 5: Connect iPhone to a Different WiFi or Computer

If you are restoring your iPhone using WiFi, switch to a different WiFi connection and test if the restore succeeds:

  • Connect your iPhone to another WiFi router in your house, office, or a mobile hotspot.
  • The issue may be related to your current WiFi network congestion or firewall settings.
  • A new WiFi connection will rule out any network-related causes.

Similarly, if restoring using a computer, try connecting your iPhone to a different computer:

  • Connect your iPhone to another computer using a different USB-to-Lightning cable.
  • Attempt the restore from backup on the new computer.
  • This should isolate whether the issue is being caused by your computer or cable.

Solution 6: Erase Your iPhone and Set Up as New

As a last resort, you can perform a clean install of iOS by erasing your iPhone and setting it up as new:

  1. Backup your iPhone data to iCloud or iTunes so you have a copy.
  2. On your iPhone, go to Settings > General > Reset > Erase All Content and Settings. This will erase your device and install a clean version of iOS.
  3. Setup your iPhone again from scratch without using your backup. Download apps individually and sync data back from iCloud.

This completely resets your iPhone to factory conditions, eliminating any software bugs corrupting the backup restoration process.
