iPad 12.5

It appears you have an original iPad Air from 2013, which cannot be updated to any of the newest iPadOS versions. If it is the original battery in your 9 year old iPad, it would surely be failing at this point.

Apple does NOT replace batteries in iPad. They instead offer a reduced price in return for a refurbished replacement device. That said, an original iPad Air is no longer listed on Apple's repair chart, so it may not be eligible to have it replaced for a refurbished device with a new battery.

Given it is now very out of date in terms of software updates, it honestly would not be worth investing in. It would be far better to get a new iPad at this point, which will also run circles around a 9 year old device.

If your iPad is nesr full of data, that could explain the slowness of your iPad.

ALL iOS/iPadOS devices need to constantly maintain, at the very least, a minimum of between 3-6 GBs of free data storage space, AT ALL TIMES, to insure normal/nominal functionalities/operation and general overall performance of any iOS device running iOS/iPadOS.

If the battery is charging slowly and running down quickly, then the battery in this almost 9-year old iPad maybe on its way to failing.

That iPad is too old and will be completely oldsolete by the end of 2022.

NOT worth putting any money into an iPad that is no longer supported by Apple and soon will NOT have any more third party app support.

It is past mid 2022, now.

You really need to seriously consider a purchase of a new iPad model OR a much, MUCH “newer” and less expensive, refurbished or used iPad models, from better known, trusted Apple product/device retailers/resellers, some locally or from online, on the Web/Internet, capable of running the latest iPadOS versions.

There are PLENTY of less expensive, newer, older iPad models that can run the latest, current versions of iPadOS.

If you need OR ONLY able to purchase older, less expensive iPad models, look at older iPads from 2015 and later.

All of these older model iPads below, CAN, currently, run the latest releases of iPadOS 15 and the up and coming iPadOS 16 releasing sometime in the Fall of 2022.

2015-2017, 12.9 inch screen iPad Pro models. ( 1st gen Pencil support )

2017,10.5 inch screen iPad iPad Pro models ( 1st gen Pencil support )

2017, 9.7 inch screen iPad 5th gen models ( NO Pencil support )

2018, 9.7 inch screen iPad 6th gen models ( 1st gen Pencil support )

2019, 10.2 inch screen iPad 7th gen models ( 1st gen Pencil support )

2020, 10.2 inch screen iPad 8th gen models. ( 1st gen Pencil support )

2019, 7.9 inch screen iPad Mini 5th gen models ( 1st gen Pencil support )

Get the largest internal data storage model you can afford as NO Apple iOS device has ANY expandable storage.

I am sorry that you had to learn all of this, but this does not change any of the facts regarding these very old iOS devices.

Please recycle these old devices properly and responsibly.

Sorry & Best of Luck to You!

Hello. The more older an iPad gets, the slower it becomes, especially if it is not on the latest software version. If your iPad is able to update to ipadOS 15, update it. This is a list about compatibility:

To update your iPad: Update your iPhone, iPad, or iPod touch - Apple Support

If you are unable to update, you could change the battery. If you have apple care, it could be free of charge: AppleCare Products - Apple

Hope this helps!

If you decide to go down the path of purchasing used, secondhand Apple devices, here is how to avoid purchasing an Apple iOS/iPadOS device with user activation lock, in the future.

If you purchase any iPad, or any Apple iOS device, for that matter, used/second hand, online, or even in-person, make sure this iPad does NOT have user activation lock and has been properly reset for sale.

A properly reset for sale iPad should initially power up to an animated, multi-language “Welcome” screen.

DO NOT take the iPad seller's word that this iPad is user activation lock free!

We have seen plenty of used iOS device purchasers get scammed.

User Activation Lock can never be bypasss, circumvented or worked around IF there is no correct previous/original user information to be able to do so.

Apple doesn't get involved with ANY user activation locked, used/second-hand sold devices, either.

So, buyer beware!

If purchasing a used device in-person, power the iPad ON

If the iPad DOES NOT display the initial animated, multi-language “Welcome” screen, then pass on purchasing this iPad.

If the iPad powers up to any other screen, then forget purchasing this iPad.

You cannot trust that the seller actually has the correct needed info to properly reset the iPad back to factory settings right then and there before the actual purchase and exchange of money for the iPad, in question.

Pass on the device!

If you are purchasing this used iPad online ask the seller to provide multiple images, either online or be sent to you via email, showing this animated, multi-language “Welcome” screen of the interested in purchasing iPad model.

Even better, ask for a short video be sent to you showing this animated, multi-language “Welcome” screen, in action and in its entirety, posted to the online ad or emailed to you.

If the online iPad seller refuses any of these requests, pass on the iPad. DO NOT buy!

Good Luck to You!
