Here’s How Long the iOS 17.0.2 Update Takes



Apple’s iOS 17.0.2 update is a small point upgrade, but it could take quite a bit of time to install on your iPhone.

The company’s finally pulled its iOS 17 operating system out of beta and the software brings a long list of changes to the iPhone. The update includes a host of new features, enhancements, and security updates.

Apple’s begun patching the operating system with new firmware and the latest version is iOS 17.0.2.

If you’re moving your iPhone from iOS 17.0.1 to iOS 17.0.2, you get the shortest list of changes and the smallest download size.

If you’re upgrading from iOS 16, the iOS 17.0.2 download will be much larger because it delivers the changes from update(s) you haven’t installed. In this case, that’s iOS 17.0.1 and iOS 17.0. The iOS 17.0 update was around 3GB for users currently running iOS 16.6.1.

While some of you might want to skip the iOS 17.0.2 download for the time being, most people should install the software today, or, at some point in the near future.

If you decide to install iOS 17.0.2 on your iPhone, you’ll want to set aside some time to get the upgrade properly installed on your device.

Moving an iPhone from one version of iOS to another can cause problems so you’ll want to monitor the download and installation.

We can’t tell you exactly how long the process will take because it will vary. That said, we can help you approximate how much time you should set aside should you choose to install the new operating system on your iPhone.

Sync (Optional)5-45 Minutes
Backup and Transfer (Optional)1-30 Minutes
iOS 17.0.2 Download8 Minutes to 30 Minutes
iOS 17.0.2 Installation10 Minutes to 15 Minutes
Total iOS 17.0.2 Update Time18 Minutes to 1 Hour+


Before you start the iOS 17.0.2 download make sure you’re prepared.

If you don’t know how to properly prepare for an iOS upgrade, take a look at our pre-installation guide. It’ll walk you through the most important steps to take before you start the installation process.

You should be able to get through these steps in 30 minutes, but it all depends on your skill level and the current state of your iPhone.

If you haven’t backed up your data in awhile or you if you aren’t familiar with iOS 17, the pre-installation process could take you a longer.

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 17.0.2 Download

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

Again, the exact size of your iOS 17.0.2 download will depend on your iPhone model and the version of iOS it’s currently running.

If you’re on the latest version of iOS 17, you’ll see the smallest download size. If you’re running an older version, your download will be larger.

If you’re connected to a fast Wi-Fi network, the iOS 17.0.2 download could finish up in less than 10 minutes. If your connection is slower, or you’re downloading during peak hours, you might be looking at a lot longer than that.

iOS 17.0.2 Installation

Once your device is done pulling iOS 17.0.2 from Apple’s servers, the installation process will begin.

On newer phones, the iOS 17.0.2 installation process could take about 10 minutes to complete. It took about nine minutes to install on an iPhone 12 that was previously running iOS 17.0.1.

Your iPhone might reboot itself a couple of times during the installation process, but this is perfectly normal. Your device should boot up in regular fashion 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 operating systems 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 currently rolling out iOS 17 support updates.

You’ll also want to poke around your phone for bugs and performance issues. If you notice something take a look at our list of fixes for common iOS 17 problems.
