My iPhone 6S is virtually unusable since the update I unplug it from the charger with 100% battery, then within a few minutes the battery goes to the other extreme of 1% and the phone shuts down So a 99% battery drop within minutes of it being unplugged from the charger I also found out that the bluetooth does not work properly with my car radio (SEAT Leon FR 2015), because it no longer shows the track list on the car radio (shows 'Bluetooth audio device: no track list available) which means I cannot select music via the car stereo and have to select it on the phone instead Very disappointed and thinking of moving away from Apple
