Had a similar experience when upgrading an N800 a while ago.
IIRCC the fix then was to delete and recreate the swap file.

Thanks for your tip. But I didn't use any swap file.

Anyway, seems that disabling R&D mode fixes the problem.

Moreover, besides having that mode, I had activated usb-host-mode and
rd-flags=serial-console, so I'm not sure if some of this sets were
draining the battery.

But thank you everyone for your help!

Serial-console R&D setting will definitely drain your battery and
if you don't have anything connected to the device serial connection
pins, it will cause random reboots and other funny effects (because
random serial input sometimes manages to match SysRq keyboard
shortcuts).

Note that R&D settings aren't cleared when the device is flashed
and in general users should have any need for them...

I have exactly the same problem but the R&D mode is disabled on my device!

Have you got another idea ?

I had also rd-flags=serial-console and usb-host-mode enabled.

Check also if you have swap enabled (maybe it is corrupted).

It's the serial-console setting, not the rd-mode that is causing the
battery to drain very fast.
