Was moderately happy with my battery yesterday, which did 9.5h of activity over almost 2 days of standby use. Got down to 1%, plugged it in, went to sleep, woke up, came to work, put phone on shelf.
Phone has been actively doing something while on shelf, dropped from 100% to 79% over two hours of sitting on shelf. Battery stats in settings say "safari audio" has been working non-stop. I am not using Safari audio (what is that?). Between waking up (100%) and checking phone (79%) I have not used Safari at all - I did not start something which is left playing on a loop.
What is that????
