Yeah, yeah, 4G is not the "problem". I'm eating my words after all. But it grates on my design senses such that I think Apple is reaching here. Every single part in the device has a certain power draw, and you have to be judicious about them. You get caught in a box were every decision you make results in some unsavory consequence: weight, size, and heat. A 42 WHr battery to power the device to 10 hrs on WiFi and 9 on LTE!
When I see that 42 WHr battery, and it only yields the same usage performance as prior iPads, it just grates.
Hopefully the tear downs and further testing will determine the partials. Based on the 10 and 9 quoted hrs, the MDM9600 is costing 4.2 WHrs. That's ~80% of the iPhone battery. The display, WiFi and the A5X is burning about 3.5 to 4 W when running video or browsing over WiFi. That's 50 to 70% more than the iPad 2. Just don't like it. I'd rather they keep the total power draw less than 3 W and make the device thinner, lighter and last longer.
They're caught in a mis-timing with the immaturity of display tech as it is apparently still amorphous silicon and it seems only Intel can produce CPUs at 32 nm or better.
