My iPad had been spinning a lot lately. Do you know why it does even after doing clear it the hard reset. It stops temporarily until I do other stuff. I uploaded my screenshot recording to YouTube. https://youtu.be/jhNBPWqi6VU
usually a sign of low or interrupted signal.
Could be either, why not force close all apps and webpages, hard reset again,and then try Youtube, make sure everything is up to date also. Check incoming signal with phone, yadda,yadda.
How old is iPad,and what iOS are you on ?
Watching the video, I'm not sure what you are complaining about. You mean the spinner when you go into Settings / Battery? Both my iPhone X and iPad Mini 4 do that every time. That's standard behavior as far as I am concerned; it's been that way for as long as I can remember.
