After updating my 6S and iPad mini 2, I noticed their battery lives are significantly reduced, especially the iPad. My mini 2 sometimes get very warm as well, and it cannot last a day, which is very bad. Both usage and standby are showing the same amount of time. I did not modify anything from pre 9.2. On my 6S, I have uninstalled Facebook app before 9.2. Main app that uses battery is shown to be Safari, despite minimal on screen time. Anybody having similar issues? One thing I could think of is iCloud issues with Safari, but it's hard to tell.
