Martin, for whatever it's worth, the following upower bug I filed might also be related - since an idle nexus 7 has a longer battery life than 20 hours, one would hope.

It will say that the battery is at 43%, 1 hour left, then say it is low with 43% and 1 minute left. At some points it says the battery is critical and shuts down the screen, only to re-awake soon after saying that the battery is simply low. The percentage seems to remain constant, however the time left changes.
