What is the average battery life those with a mini 4 have been experiencing? My brand new mini has never lasted beyond 8 hours, and it seems like it's getting worse. I have all of the common culprits of battery drainage off including background app refresh, I use it on below half brightness, just can't seem to figure out what the issue could be. My previous mini 2 lasted much longer with the same usage, and I simply restored this mini 4 with that backup and used it as I normally would. --- Post Merged, Mar 23, 2016 --- I should add that the bottom right side of the iPad gets very warm when watching videos on YouTube and it seems to drain percentages faster while watching them as well.
