I know this very well may be a trivial question, but I am genuinely curious as to why the IPP has a higher mAh capacity (roughly 9k) versus the 15" mac book pro (7k).
 
Because those damn Intel processors are taking up too much room.

In all seriousness though I would assume the difference has to do with the MBP using a higher voltage than the iPad. So it could have a higher Wh capacity (better indication of total energy available) yet lower mAh capacity.

Edit: Yup! The battery in the 2016-2017 15” MBP is 76 Wh, but operates at 11.4 V which creates a 6670 mAh capacity. The 12.9” iPad Pro’s battery is only 34.8 Wh, but since it operates at a much lower voltage of 3.77 V the mAh capacity is a higher 9237 mAh. Again, Wh is a better indication of power capacity.

As Ace already stated, always compare Wh, not mAh. Units operate at different voltage levels. Pretty self-evident for me, even as non electronic engineer.

Btw I also love the beefy 99.5Wh beast in my 15" MBP 2015.
