How to update my iPad to iOS 15.0?

It may be your iPad can't run iPadOS 15.

There are different ways to ensure the highest iOS/iPadOS that your device will support is installed on your device.

This support article has instructions about updating an iPhone or iPad wirelessly --> Update your iPhone or iPad - Apple Support

You can also use Mac and PC computers to update system software, as outlined in this support article --> Update iPadOS - Apple Support

Use this support article to identify your iPad model --> Identify your iPad model - Apple Support and then the list below to find out what your iPad is capable of running. Alternatively—and somewhat easier—is to simply try updating it and see if it will update. When updating, your device will update to the highest version currently available that it will support, or it will just say it is up to date (and can't go any higher) and won't install anything. If you want to run a higher system version than your current device will run, you need to buy a newer device.

Here's a list of iPad models and the iOS/iPadOS versions they are capable of running:

In additionwaaaay too far behind in iOS/iPadOS upgrades/updates.

If you have access to a full computer, like a Mac or Windows PC, try either using the Finder on a Mac that has the newest macOS Catalina, or later macOS, installed OR with an older Mac with an older Mac OS, download and install the latest iTunes version ( or latest iTunes for Windows PC ), make sure the Mac or Windows PC is connected to the Internet, connect your iPad by the USB charge cable to the computer and let the iTunes application upgrade/update that iPad model, using the iTunes Software Update feature, to its current, maximum OS of iOS 12.5.7/iPadOS 15.7.5/iPadOS 16.5, depending on your year and model of iPad.

A 2013 iPad Air 1st gen, iPad Mini 2nd gen and 2014 iPad Mini 3 can ONLY be updated to iOS 12.5.7.

A 2014 iPad Air 2 and a 2015 iPad Mini 4 can ONLY be upgraded to iPadOS 15.7.7

iPad models from 2015 can be upgraded to the latest iPadOS 16.7.

Any iPad from 2017 and later/newer can be upgraded to the latest version of iPadOS 17, except the 2017 5th gen iPad, which CAN ONLY be upgraded/updated to the latest iPadOS 16.7.

Make sure your iPad is, at least, charged to 50% or greater to attempt this.

Also, make sure your iPad has, at least, between 6-8 GBs of free internal data storage space for downloading and installing a major iOS/iPadOS upgrade.

Make sure your desktop/laptop computer has plenty of internal drive storage space, also.

Also, make sure to do a backup of your iPad's data, prior to upgrading/updating.

Backup to Apple iCloud and/or a full Mac or Windows PC using the same iTunes app OR, if a newer Mac running macOS Catalina, or later, making a backup using the macOS Finder app.

If NO access to a Mac or Windows computer, you will have to seek help from a good friend or family member, with a full Mac or Windows PC, to help you out

OR

Search online to locate and call contact your nearest, “local” Apple Store location to try/attempt to make an appointment to get your Apple iPad upgraded/updated to its latest iPadOS 15 version.

OR, alternatively, use the “Support” link, at the upper right hand corner of every Apple Support Community Webpage to attempt to schedule an appointment with your nearest Apple Store location.

Apple Store employees will be glad to help/assist you.

Best of Luck to You!

It is a little hard to help/advise you when you provide little to NO useful information about your iPad.

Lots of iPad year and models.

Here are my questions to you.

Can you, please, confirm what year and model iPad do you have/own?

The “A” model number can be found on the aluminium back of your iPad, in very small print, right under the larger bold print “iPad” on the back of the iPad.

AND/OR

Supply the “M” model number, which can be found in the Settings app, under the General settings panel, then tap About.

Your iPad maybe too old.

What iOS/iPadOS version is this iPad, currently, running? Your iOS/iPadOS version maybe too far behind in iOS/iPadOS versions OR cannot be upgraded/updates any farther than what your iPad OS version is already, currently, running.

Again, your iPad maybe too old.

If your iPad is nearing 11-12-years old, upgrading the software on these old iPad models is a waste of time and efforts.

These very old iPad models are no longer supported and there is no more third party apps support for any very old iPad models stuck on either iOS 12.5.7 AND iOS 10.4.4 and earlier.

These very old iPad models are very underpowered and obsolete!

What is the rated, internal data storage space/capacity of your iPad model and how much of this free, internal data storage capacity is left inside of your iPad model?

All of that additional info can, also, be found in the Settings app, General settings panel, About.

Your iPad needs sufficient free internal data storage space. At the very least, 7-8 GBs or greater internal, free data storage space.

Is your iPad using/running a VPN? You need to, temporarily, disable the VPN.

Is your iPad running an iPadOS Beta version? You need to remove/uninstall the iPadOS Beta software before you will be able to install the Apple “officially” released version of an iPadOS upgrade/update.

Also, make sure your iPad is charged to, at least, 50%, or greater, before attempting the iPadOS upgrade/update.

Please from 13.0
