says the LCD display consumes 20mW. So if you turn on the reader every time you want to read then it is not obvious that this power consumption affects the total reading time so much. Was it 20 hour reading time that was claimed for the Cybook? That is 50mW with a 1000mAh battery. So you get 15h or so with the LCD display. |
It hibernates. The CPU is based on the ARM architecture and therefore doesn't really need to be shutdown. The eInk doesn't need to be powered off cause it only uses 1mW of power at idle. I can leave my eReader on for days without it really affecting the power. Everyone would be turned off with 15h operating time. Hell, my wife would kill me if her eReader didn't last at least a week and a half.
It's very efficient with an ARM cpu and a eInk display, than it is with an ARM cpu and an LCD display. Especially if you're a slow reader, or someone who reads over time (like most of the world). The LCD would only benefit those that would breeze through a book a day, or enjoy turning off and powering up their eReader.
So, it depends what you're going for. How fast you read or page changes over time. I'm sure most people would rather base their battery's lifetime on page changes than on how long their battery has to live.
