Has anyone seen any dramatic drop in battery life on their iPhone 6s since iOS 9.3 and 9.3.1 have been released? Usually when I go for my regular 90 minute run with the GPS on and music playing my battery drops from 100% to around 80-85%. Ever since I upgraded to iOS 9.3 and 9.3.1 it is dropping to 60%-65%, so much so that I can actually see the 1% drops around twice a minute. Nothing unusual is showing in the Battery section of the settings with no screen or background activities showing excessive time and nothing out of the ordinary. As I am typing this it is currently showing 1h 10 mins of use with the battery at 65%, normally this would be at around 85% for me. It may not be an issue with 9.3 or 9.3.1 but this only started happing on the actual release day of 9.3 and the recent release of 9.3.1 has not helped at all. If I go for the run with Airplane Mode on and just the music playing it also drains the battery down to around 65%-70% on a 90 minute run so I can't see it being a GPS, Bluetooth or Apple Watch issue. I have reset all settings and wiped and restored the entire device which has not helped in anyway. The other strange thing is that when I plug it in to be charged from around the 65% mark it is charging remarkably fast going back up to around 80% in around 3-4 minutes and up to 90% in around 10 minutes, again this has only been happing since the dramatic drops starting happing at the release of 9.3 Has anyone else got this issue or any advice on what to do? Is there something new in 9.3 that I have not turned off that is draining it? Apologies if I posted this in the wrong section. --- Post Merged, Apr 3, 2016 --- This is what has been using the battery according to the Battery page, nothing looks abnormal and yet a normal 90 min run drains it to 65%.
