How can I tell if my ipad 2 needs a new battery?
iPad 2, iOS 9
Question marked as
If you are running an iPad 2 that has never had its battery replaced, you probably need a new battery or will need one very soon. You should make an appointment at the nearest Apple Store to have it checked out. You haven't mentioned your symptoms, but you must be having issues that prompted your question. If it isn't the battery, they will be able to tell you what the problem may be.
