[Dulin's Books]

we're talking about battery life. if you want to put the tablet in sleep/stand by then go ahead. but then the reader has to be put in sleep/standby as well.

but the concern was that at 15 hours of reading time there isnt really much advantage in the eink display over the rival lcd device that can go 12 hours.


to test that you need to test two devices in a simliar state with similar batteries. if you want to test them in stand by, fine.

by if you just test them "on" and wait til the end of the day you will get your answer much quicker than putting them in standby.

the reality is that an ink display device will last twice as long or more with half the battery of the lcd device because just sitting there "on the eink display is using no power while the lcd display- even the best most eifficient non-bistable lcd- is constantly refreshing and drawing power.

its like saying car A with a 5 gallon tank doesnt get any better gas mileage than car B with a 10 gallon tank because they can both go 300 miles on a tank. comparing how far they each go on a tank without knowing how much each tank holds is not actually comparing the efficiency .
