I've already updated to the latest version of 13, rebooted several times and went through Settings to turn off location services for most apps. ???I don¡¯t stream on Books, just read what I have downloaded. ?I keep brightness turned low.
This accelerated drain has been going on for days. ?So I¡¯d think any background updating of photos, etc. should be finished. ?Yet in the last three hours with only maybe 10 minutes total of use, the battery is already down 11%.
As suggested in the article Pat sent (many thanks) I¡¯ve just turned off lift to wake. ?Maybe that will help.
