I say this because, unlike all the previous models of Kindle, after the KOA2 has been asleep long enough, it goes into some kind of suspend mode. (You can tell when you turn it on, you have a few seconds of "Please Wait" before it's ready to resume.) It does not index *any* books when in that low power state. It only indexes however many books it can in the minutes from when it's first turned off before the final power save mode.

Yes, battery life on the KOA2 is worse than on any other e-ink kindle even though it is the only one with the deepest sleep mode. It has a smaller battery, even though it has more cores and even higher speed. It also has more screen to light up and its warmer color might (or might not) need more current. It also uses more LEDs to light that larger screen.
The KOA2 also seems to want to outshine brighter ambient light than other models.
But most KOA2 owners seem to get over a week out of a charge.
Some say they lose 10% to 20% per day with wireless off, the light off, no indexing, and only a few hours reading per day. These almost always turn out to be indexing anyway, but that is an Amazon bug not specific to the KOA2 model, and can be mitigated by the user.
Amazon stretches the truth on battery life for all their reader models, even more so with the KOA2, but not nearly so bad as some of the claims on this thread.
