This is an extreme battery test of the new iPad Air 2. I'm going to run it nonstop with WiFi and Bluetooth on, playing YouTube videos from YourFastLife Car Channel with the screen at full brightness and volume at max. Let's see how long it lasts!
10:39 - Begin 100%
12:30 - Battery 69%
13:23 - Battery 45%
15:19 - Battery Dead
4 hrs 40 minutes
NOTE: iPad ran until dead. It only paused 2-3 times in last 20 minutes to warm me of battery. I was able to ignore and continue playing video.
