I want to update my ipad 4th generation to ios 16

Update support for iPad 4th gen ended September 2017. The final iOS releases for this model were iOS 10.3.3 (Wi-Fi Only models) and iOS 10.3.4 (Wi-Fi + Cellular). iPad Gen 4 cannot be updated to any later major version of iOS as it lacks the minimum hardware requirements and processing power needed to run more recent versions. The 32-bit platform upon which the iPad 4 is based is obsolete.

If you want to upgrade to newer software I would recommend that you get a newer iPad Model.

Newer models are all able to be updated to the version iPadOS 16.0

• iPad Pro (all models)
• iPad Air (3rd generation and later)
• iPad (5th generation and later)
• iPad mini (5th generation and later)

If your iPad is capable of being updated to a more recent version of iPadOS, check in Settings -> General -> Software Update to check for the latest update and install it.

Make sure to remove any beta profiles before installing the latest version of your software.

Update support for iPad4 ended September 2017. The final iOS releases for this model were iOS 10.3.3 (WiFi Only models) and iOS 10.3.4 (WiFi & Cellular). iPad4 cannot be updated to any later major version of iOS as it lacks the minimum hardware requirements needed to run more recent versions. The 32-bit platform upon which the iPad4 is based is obsolete.

App Developers have dropped all support for 32-bit devices - and have withdrawn older versions of their Apps from the Apple App Store. Withdrawal of Apps supporting older models of iPad is making their utility and usefulness significantly more limited. Once compatible versions Apps are withdrawn, you’ll not be able (re)download or (re)install them.

If Apps that you need to use now have higher minimum iOS-version requirements than your iPad is capable, your only option is to replace your iPad with a much newer or current model.

For information, here is a list of the highest version of iOS supported by the older models of iPad (for simplicity - “generations” are shortened to a number) that are restricted in their ability to be updated:

32-bit devices (obsolete)

iPad1 - iOS 5.1.1

iPad2, iPad3 and iPad mini1 - iOS 9.3.5 (WiFi Only models), iOS 9.3.6 (WiFi+Cellular)

iPad4 - iOS 10.3.3 (WiFi Only), iOS 10.3.4 (WiFi+Cellular)

64-bit devices

iPad Air1*, iPad mini2 and iPad mini3* - iOS 12.5.7

iPad Air2, iPad mini4 - iPadOS 15.8.3

iPad5, iPad Pro (9.7"/12.9" 1st generation)* - iPadOS 16.7.10

iPad6, iPad Pro (10.5"/12.9" 2nd generation) - iPadOS 17.7.3

(*) obsolete

Newer models are all able to be updated to the current version - iPadOS 18.2

• iPad Pro 13" (M4)
• iPad Pro 12.9" (3rd generation and later)
• iPad Pro 11" (1st generation and later + M4)
• iPad Air (3rd generation and later + M2)
• iPad (7th generation and later)
• iPad mini (5th generation and later + A17 Pro)

An iPad 4 isn't capable of 11 or above; they require an A7 or better CPU. The people on these boards are mostly other customers and can't update it in any case.
