Of course it depends on the consumption (settings of the speed, backlight, etc...). It also depends on the unit. For example, I made some tests with 4-5 Primers, and - in the same condition - the overall consumption could be +-20%. I guess that the variability is due to the backlight.
Most of the power is consumed in the backlight.. It is quite easy to cut-off this load. Then, you can probably disable the MEMS.. but I don't remember whether RLink still consumes some current or not.
I have already set the backlight to the darkest level. I put the CPU Frequency to the lowest level, too. Maybe I will try to disable the MEMS, too. But according to this point, Im not sure, that I do that. I will think about it.
