Why does my ipad die before it reaches 0?
My iPad will die at a random number, then when I plug it in to an outlet, it will double in percent (For example, dies at 20, charges at 40) and then it stays at that number. Whenever it dies AT 0 it takes a very long time to charge up. This never happens when I am offline. Is there anything I can do to prevent it besides keeping it on the charger at whenever I use it? I have had this device for about 3 years, so could it be at it's end of life? I can still use it, however it often crashes, and is very slow. Another iPad I have has been with me for the same amount of time, but it never does that? !Please Help!
iPad Air, iOS 12
