I may have missed it, but was there any mention in the slides of the battery capacity used to generate their battery life metrics? They claim ~5 hours of 720P video but have it consuming >1W of power. Wondering about the current draw, seems like this would need something like a 3000mAh battery to last that long with that high of power consumption?
It makes more sense to measure battery capacity in Wh, Ah doesn't tell you much without knowing the voltage. At 1.2W power draw 5 hours of video take 6Wh.
Assuming a typical 3.7V Li-ion cell this means 1.62Ah. Adding some margin, they probably used something close to 1.8Ah .
The new FiOS HD DVR, arguably the biggest update since Verizon released a DVR, thanks to its external storage support, enhanced multi-room functionality and slick new 16x9 HD user interface.
