Apple makes it pretty convenient to check which version of iOS or iPadOS you have installed on your iPhone or iPad.
If you need to check if your device is compatible with a particular app or accessory, or if you simply want to know what version of the OS you're currently using, you'll need to head to the Settings app on your device. Here's how to do it.
How to find your current iOS version
1. On your iPhone or iPad, open the Settings app and then tap General, about halfway down the page.
2. At the top of the General page, tap Software Update.
3. Here you can see your current OS version, and check if there's an update available and ready to install. If an update is available, you'll see it here and can tap to start the update.
Another way to see what OS version your device is running is to open the Settings app and tap General. Then, at the top of the General page, select About instead of Software Update.
The About page lists all kinds of information about your device, including the software version, serial number, and details about how much storage space is free.
You can also use this page to check what iPhone model name and model number you have. You can't see if there's a software update available from this screen, though, which is why this page may not be as handy as the Software Update page.
