Battery life viscal capacity
what is my battery capacity?
iPad Air 2, iPadOS 13
iPads do not have a battery capacity option like that found in an iPhone.
That is because iPad batteries are much larger and will last much longer than the smaller sized batteries used in iPhones.
If you have a 2014 iPad Air 2, a 2014 iPad Air 2 will be 7 years old this year.
If your iPad is having various battery issues, It is possible that the internal, rechargeable battery in this iPad maybe failing.
I advise you 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 Air 2 diagnosed and options presented to you.
OR, failing that,
Contact Apple support via the contact support link located at the upper right hand corner of every Webpage of these Apple support communities.
Use the Battery, Device Performance and Connectivity support categories.
OR
by installing and using the Apple Support app found in the iOS App Store.
