Im getting anywhere from an hour to 2 hours less battery life on my 2018 12.9 iPad Pro. When I was using my Logitech slim folio pro I was getting an average of about 12 hours battery life and now I’m getting 10.5 hours. When I had the Magic Trackpad 2 and was using it with my iPad Pro I did notice I was getting less usage. I wonder if this will be fixed in a future update. Just to confirm I have disabled the keyboard backlighting.
