Update iPad Air 2 to iOS 15.02 - iPad keeps shutting down

First of all, I would contact Apple Support directly (they have tools to run remote diagnostics, battery status included), using this link:--> Get Support

If they say battery is okay, try these two basic troubleshooting steps:

A "forced" restart of your iPad, using these instructions:

• On an iPad with a Home button: Press and hold the top (power) button and the Home button at the same time. When the Apple logo appears, release both buttons.
• On other iPad models: Press and quickly release the volume up button, press and quickly release the volume down button, then press and hold the top (power) button. Only when the Apple logo appears (it might take 15-30 seconds), release that button (ignore all other screens that might appear).

If the issue persists, something could have gone wrong during the latest update procedure.

I would try to install a fresh copy of iOS/iPadOS. To do this, create a full backup of your iPhone/iPad (1), then restore it to factory settings (you need a computer to perform this step) and, in the end, set it up as new (2).

When done, restore data from your previously made backup (3).

Follow the instructions provided in these support articles:

(1) How to back up your iPhone, iPad, and iPod touch – Apple Support

(2) Restore your iPhone, iPad, or iPod to factory settings – Apple Support

(3) Restore your iPhone, iPad, or iPod touch from a backup

If the issue still persists, make an appointment (*) and have your device inspected at an Apple Store or AASP (Apple Authorized Service Provider) among this list:--> Apple – Location Selector. After checking it out, they'll give you all the available options.

All reachable batteries have a finite life. The battery in your iPad Air2 may be approaching the end of its usable lifespan.

If the iPad is still functional, you might consider making direct contact with Apple Support - and request a remote battery diagnostic test. You’ll find the Get Support link at top-right of this page. You can also initiate a support case using the excellent Apple Support App. If not already installed on your iPad, it can be obtained from the App Store:

Alternatively, the technicians at the Genius Bar of your local Apple Store will be able run full diagnostics - and provide appropriate advice and options on the basis of test results.

Well, when performing updates, inconveniences can always happen, but it is difficult for us, just users like you, to diagnose those problems remotely.

That is why I have only listed the steps that can be taken in such circumstances.

First and foremost, the description of your problem sounds just like something related to the battery. If it has never been replaced, bearing in mind that that model was released in 2014, the battery may have reached (or is about to reach) the tipping point in its life, and have unpredictable behaviors.

Regards and best of luck.

DJG77,

After each "major" update, the device itself, for 24-48 hours, has to perform a series of very heavy and tiring "house chores" (depending also on your wifi reliability and speed).

Among these many activities, just think of the reindex and cleaning of what has become obsolete on the device, especially if there are many apps, documents, media on it.

I don't want to convince you that this is a coincidence, but it is very likely (if your battery has never been replaced). Why not get rid of this doubt by checking the status of your battery?

Giulio

Your battery issue after an upgrade/update is just coincidence.

This is NOT a common issue.

Get your iPad looked at by Apple.

Good Luck!
