But, still, only 80mah a day . So 750mah scaled up to iPhone battery size. So abut 1/5 of the average daily power requirement for an iPhone. Even at that rate you’d need to use a supecapacitor to even out the load profile.
OTOH, in terms overall energy, it would be about the same as about a 50 litre lithium ion so it is rediculously dense, just low output

It could be made to work if software wasn't so violently inefficient (both CPU and data usage) and screens weren't so large.

If my maths is right (and it's past midnight, and I'm not entirely sober, so might not be) and my search results are too, 15 x 15 x 5 cubic millimeters is approximately 9.68 times smaller than an iPhone battery (95 mm x 37.6 mm x 3.05 mm, ish), but if energy capacity scales linearly to volume then its ~12,500 times lower capacity per volume than an iPhone battery.
