20 new stacks + back boardd logs since yesterday on my iphone 6![]()
i updated to 8.1 beta 2 since that is supposed to get rid of those errors. i had a ton of them. i think it was the root cause of my battery drain as well. apple rep said core apps like SMS and Mobile Cal were very active in the background and not stopping the way they were supposed to. i logged out of and back into iCloud to see if it helps and loaded 8.1.
Pretty sure backboardd is something to do with the Touch ID sensor as I put my finger on it yesterday and it crashed the phone and the log was backboardd. I used to have stacks+backboardd, but mine stopped a while ago.
