Check your current iPad model and iOS version first

Before you start an update, you need to know what you're working with. Go to Settings, then tap General, then About. You'll see your iPad model name at the top (iPad Air, iPad Pro, iPad mini, or plain iPad) and the current iOS version number below it — something like "17.2" or "18.1".

Write down both pieces of information. Not all iPad models can run the newest iOS versions. An iPad from 2015 might max out at iOS 16, while a newer model runs iOS 18. Apple's website lists which models support each version, but the quickest way to know is to start the update process — your iPad will tell you if it's compatible before you commit to anything.

Key Takeaways

  • Updates read over Wi-Fi and take 20 minutes to several hours depending on file size and your connection speed.
  • Plug your iPad into power before starting, because the update will fail if the battery dies mid-process.
  • Back up your data through iCloud or a computer first, so you don't lose photos, messages, or app data if something goes wrong.
  • You can update through Settings on the iPad itself, or through a Mac or Windows computer if your iPad won't start the update.

Back up your data before you update

An iOS update rarely causes data loss, but it happens. The safest move is to back up first. You have two options: iCloud (wireless, automatic) or a computer (faster, more control).

For iCloud: Go to Settings > [Your Name] > iCloud > iCloud Backup. Turn on iCloud Backup if it's off, then tap Back Up Now. Wait for the backup to finish — you'll see "Last backup: now" when it's done. This works over Wi-Fi and takes 5 to 30 minutes depending on how much data you have.

For a computer: Plug your iPad into a Mac or Windows PC with a USB cable. On Mac, open Finder and click your iPad in the sidebar, then click General and Back Up Now. On Windows, open iTunes or the Devices app, right-click your iPad, and choose Back Up. A computer backup is faster and stores everything locally on your machine instead of in the cloud.

Update through Settings on your iPad

This is the most common route. Plug your iPad into power — do not skip this step. Go to Settings > General > Software Update. Your iPad will check for updates and show you what's available.

If an update is ready, you'll see the version number and file size. Tap read and Install. The iPad will read the update file over Wi-Fi (this can take 10 to 60 minutes depending on file size and your connection), then ask you to install it. You can choose to install now or schedule it for later — if you choose later, it will install overnight while plugged in. Once installation starts, your iPad will restart several times. Do not unplug it or force it off. The whole process takes 20 minutes to 2 hours.

Update through a computer if your iPad won't start the update

Sometimes Settings won't show an available update, or the read stalls. A computer can force the update through. Plug your iPad into a Mac or Windows PC with a USB cable.

On Mac: Open Finder, click your iPad in the sidebar, click General, and look for Check for Update or Update. Click it. On Windows: Open iTunes (or the Devices app on Windows 11), right-click your iPad, and choose Update. The computer will read the update file and install it to your iPad. This takes longer than updating on the iPad itself — usually 45 minutes to 2 hours — but it works when the iPad's own update system is stuck.

What happens during the update and what to expect

Once the update starts installing, your iPad will show a progress bar and restart multiple times. The screen may go black for 30 seconds to a minute between restarts — this is normal. Keep the iPad plugged in and do not touch it.

The update is complete when you see the lock screen and can swipe to unlock. Your apps, photos, messages, and settings are all still there. The first time you open some apps after an update, they may take a moment to load — this is the app updating its own code to work with the new iOS version. This usually finishes within a day.

Why security updates matter even if they seem small

iOS updates come in two types: major versions (like iOS 17 to iOS 18) that add new features, and minor updates (like 17.2 to 17.3) that mostly fix security holes. The minor ones are the ones that matter most for your safety. A security update patches a vulnerability that hackers know about — sometimes one they're already using. Delaying a security update, even by a few weeks, leaves that door open.

You don't need to update the moment a new version appears. But if your iPad shows an available update and you haven't updated in more than a month, do it soon. Set a reminder if you tend to forget. The update takes a few hours, but the security gain is real.

Troubleshooting if the update fails or gets stuck

If the update stalls during read, force-restart your iPad. Press and hold the top button and either volume button until the power-off slider appears, then drag it to turn off the iPad. Wait 30 seconds, then turn it back on. Go back to Settings and try downloading again.

If the update fails during installation, try updating through a computer instead. If that doesn't work, your iPad may have a hardware problem or corrupted storage. At that point, contact Apple Support or visit an Apple Store. Do not try to force another update — you risk making the problem worse.

Frequently Asked Questions

Can I use my iPad while it's updating?

No. Once the installation starts, your iPad will restart and be unavailable until the update finishes. You can use it during the read phase (before you tap Install), but not after. Plan for 20 minutes to 2 hours of downtime.

What if I don't have Wi-Fi at home?

You can update over cellular data, but it's slower and uses a lot of data — sometimes 1 to 4 GB depending on the iOS version. If you have a data limit, wait until you're on Wi-Fi. You can also update through a computer with a USB cable, which doesn't need Wi-Fi at all.

Do I lose my apps and photos when I update?

No. An iOS update keeps everything on your iPad — apps, photos, messages, settings, all of it. The update only changes the operating system code underneath. A backup is still a good idea in case something goes wrong, but data loss during a normal update is rare.

How often should I update my iPad?

Update as soon as a new version is available, especially if it's a security update. Major feature updates (iOS 17 to 18) come once a year. Security updates come more often — sometimes monthly. Checking Settings once a month is enough to stay current.

What if my iPad is too old to run the newest iOS?

Your iPad will keep running the last iOS version it supports. You won't get new features, but you'll still receive security updates for that version for a year or two. Eventually those stop, and at that point your iPad is genuinely at risk. That's when you should consider replacing it.
