I find it curious that in standby mode (suspend to memory) it still uses 50 mA compared to 150 mA while operational. That sounds high. It implies using only 66% less power in standby!!!! I wonde how much power is needed for memory alone?
Looking back at Cybook measurements:

The "sleeping mode" is same as standby (as all the state is in memory) so should be equivalent to DR1000 standby. Note power consumption is more than 10x lower!!!!
Assuming 3.7V, Cybook draws 0.53 / 3.7 = 143 mA while active (comparable to DR), but only 0.04 / 3.7 = 11 mA while sleeping!!!!!
They will either have to fix standby mode power use or add another 1300 mAh battery. Otherwise DR users will have to recharge anywhere from every day to at least once per week, even AFTER the power mgmt modes are implemented!
