So... I thought leaving N900 with mainline kernel on USB connection was bad... (end result was battery at 2.97V). Well... now I left the machine idle without the charger ... and result was 2.85V on battery. Li-ion batteries should not be discharged below 3.4V. As may batteries are already reported as 5mAh total capacity from time to time, I'll just have to get new ones... but perhaps you should not repeat those experiments.
