If the tablet is locked, this shouldn't happen. However I've noticed that pressing keys on the locked tablet can prevent the display from switching off: a message "Move [_*] to unlock" is displayed and the display remains on. This may be the cause of the battery drain for me, but I'd say this is unlikely (unless there's something else that occurs when one presses keys while the tablet is locked), because a key press/release would have to occur at least every two minutes.

I've started leaving the device on but setting it offline so WiFi wouldn't wake it up and it wouldn't look every 10 minutes.
Here if the wifi connection remains on during the night while the tablet is unplugged, the battery remains full in the morning. I could even use my N810 for several days without recharging it (no intensive use, though).

A few weeks ago, I had quite an intensive use of my N810 (wifi most of the time, use of web, terminal and Notes, display settings: 3/5), and the battery indicator had been full during 15 hours. So, this shows that my battery is still very good, and the battery only couldn't explain the drain.

Since I almost no longer put my N810 in my pocket, I no longer have any problem, except once while the tablet was in my bag (I don't know if this is related, though).
