I am 99% sure that on/off button puts libre in a sleep or hibernate mode. Most likely sleep(which means some power is being spent on refreshing RAM)

Why am I so sure?
Because boot up on my Libre for the first time takes much longer than 1-2 seconds. In fact 1-2 seconds is very fast for a real boot up of embedded Linux.

Still, it would be possible to fine tune Linux to boot that fast on Libre, but remember, it also has to load that huge pdf you have read last night, and that can take a while, but on/off button brings it up instantly. Thus, my conclusion that on/off button toggles some sort of sleep mode.

In any case, I have no complaints about battery on my Libre. Can read 2-3 days comfortably(4-6 hours a day).
