Apple’s iOS 15.7.1 update is a small milestone upgrade, but it could take quite a bit of time to install on your iPhone.

If you’re moving your iPhone from iOS 15.7 to iOS 15.7.1, you get the shortest list of changes and the smallest download size. If you’re upgrading from an older version of iOS, your iOS 15.7.1 download could be much larger because the changes from the update(s) you skipped are baked in.

You don’t need to follow every single step in the guide, but at the very least you’ll want to make sure your phone’s data is backed up properly.

Data loss issues are pretty rare, but if you store sensitive data (photos, videos, etc) on your device, it’s always better to err on the side of caution.

iOS 15.7.1 Download

Once you’ve prepared, it’s time to start the download process.

Again, the exact size of your iOS 15.7.1 download will depend on your iPhone model and the version of iOS it’s currently running.

If your iPhone is currently on iOS 15.7 you’ll, again, see the smallest download size. If you’re running an older version, your download could be larger.

If you’re on a fast Wi-Fi network, the download should finish up in less than 10 minutes. If your connection is slower, or you’re downloading during peak hours, you might be looking at 10 minutes or more.

iOS 15.7.1 Installation

Once your device is done pulling iOS 15.7.1 from Apple’s servers, the installation process will begin. This could take longer than the download.

If you’re moving up from iOS 15.7, the iOS 15.7.1 installation should take 10 minutes or less to complete. It took about seven minutes to install on an iPhone 7 that was previously running iOS 15.7.

Your iPhone might reboot itself a couple of times during the installation process, but this is perfectly normal. Your device should boot up normally once the installation process completes.


After the installation finishes up, you might need to spend time logging into your iCloud account, signing into your device’s various apps and services, and/or setting up Apple Pay.

You also might want to spend some time checking your important data (photos, music, etc) to make sure everything carried over properly.

After you do that, make sure you test your core applications and services to ensure they’re working normally. New iOS software can cause apps to go haywire.

If you notice an issue with one or more of your apps, try downloading the latest version. Developers are still rolling out iOS 15 support updates.
