Actually the mini is worse at battery consumption than the N7 (best) and the Fire, which have both 100% sRGB gamut, so sacrificing gamut for power was definitively not the reason. From what I read, the problem is the choice of going with IZGO as opposed to LTPS as the N7 and Fire do.

Display Backlight Power at Maximum Brightness:
Fire: 2.1 watts
Nexus 7: 1.4 watts
Mini: 2.3 watts

Display Backlight Power Efficiency same Peak Luminance 388 cd/m2 same 7.9 inch screen size area
Fire: 2.5 watts
Nexus 7: 2.0 watts
Mini: 2.3 watts
