Well at the moment it's not exactly being done by choice…

I think sometimes sync gets stuck and chews the battery. Turning off wifi typically fixes that, but sometimes the sync doesn't stop even then.
Also, in the past I've done searches in large pdfs and then changed books when the search didn't find anything. I suspect that the search actually never stopped, and then drained the battery flat. I haven't been searching in pdfs lately, so I don't know if this has been fixed in recent firmwares.
I think it is possible for other things to get stuck chewing cpu too.
All of these things are (temporarily) fixed by rebooting the device. If you notice your battery draining rapidly or it is still trying to sync minutes after you turn off wifi, make sure wifi is off and then reboot the device. This always stops the battery drain for me.

I'm seeing this even when wifi hasn't been on at all since the last reboot, and I've disabled auto-syncing. And most of the time the device is actually powered off when the battery is almost full (I've confirmed that by opening the case after a few hours with info panels enabled, it says powered off) and when I try to power it back on the next day (or two days later sometimes) it's dead.

The problem that I don't think anyone knows what in the book causes this.

That sounds like a fun bug to try to track down, especially since the odd time I've had it stay fully powered has been with the same book it drained quickly with! But I'm also seeing this happen when the Clara is powered off for some time. I put it to sleep by tapping the power button (and see the info panel say sleeping), occasionally I've checked later to verify it says it's powered off (which with my settings should be happening in 5 minutes, then a day (sometimes two) later it's dead.
