Google says it's 6700 mAh. The iPad Mini 2 has around 6250 mAh and has roughly 1.5 times the battery life of the MiPad. Not bad for the MiPad I'd say, considering the performance.

Battery lifetime and Long term performance test results added.
Performance/watt is lowest for the first data point and highest for the third.There are only three data points so far for long term performance and battery lifetime:
6/29/2014: 26.4fps, 156 minutes battery life
7/05/2014: 29.9fps, 208 minutes battery life
7/08/2014: 35.9fps, 208 minutes battery life
The perf. per watt of the first and third data point are similar to each other
Performance/watt is lowest for the first data point and highest for the third.
It's strange to see GLBenchmark 2.7 test as battery life test in GFXBench 3.0http://gfxbench.com/device.jsp?benchmark=gfx30&os=Android&api=gl&D=Xiaomi MiPad

Kishonti uses low precision FP16 shaders for T-Rex by default, that has quite noticeable impact on picture quality, just look at MP(medium precision) PSNR, hence the perfect MP PSNR for K1, looks like K1 doesn't support FP16. This combined with small amount of geometry, very simple shaders, lots of blending make this test perfect fit for tiled architectures. I don't believe lifetime results will stay the same once they move to Manhattan as power test

I see iPad mini Retina last 1.5x longer and I still think the comparison is tricky since we are comparing devices with different performance levels(K1 is 1.5x faster), image quality aside, there is not way T-Rex last times are indicator of battery life for tons of games capped at 30 or 60 fps, it's not an indicator for Tegra specific games like Trine 2, SS3, HL2, Portal, Rochard, etc either (some of them are deferred like Manhattan and will be more power efficient on K1). The whole comparison is pretty pointless, GFXBench numbers suggest me that I can get playable ~35 fps framerate for 3 hours long vs unplayable 21 fps framerate for 5 hours long on iPad Mini Retina in this specific test, so much usefull informationKishonti always used the older test in their benchmark suites. As for the rest there are indications of throttling (which are unproven yet) and the iPad mini Retina is estimated to last twice as much with a smaller battery. If and when Manhattan will become a battery lifetime test for Kishonti's benchmark suite there will be most likely a lot of new contenders from all sides.

Sounds to me like these tests would be somewhat more useful if there were various runs with the frame rate locked at different levels.
say @1,5,10,20 FPS etc and then also do a max frame rate run.

Sorry, this is nonsense. I can't check right now but unless I'm very much mistaken battery lifetime and long term performance results aren't even related (or they certainly shouldn't be).Performance/watt is lowest for the first data point and highest for the third.
