Yep. Toggled back and forth many times.I suppose you have tried toggling between usage and activity? That has worked for me in my iPhone in the past but currently running Beta 4 of iPad OS 13.1 on mine so not much point in comparing. Needless to say it's working fine on my iPad.
Have you closed all apps by swiping up? Also, did you do a hard reset of your ipad? And last, what is your version of iPad?I use it all day every day. It is my main reading device for newspapers, magazines, books, forums, etc. I used it so much yesterday that the battery went from 100% to 25%
