This is very true. You might have a look at what applications are running on your N900 on the moment your try to charge it from a low current source such as a PC USB port.
Full CPU power being used on the N900 might be pulling more energy from your battery than it can suck from the charging source.

I found that an older Nokia 800mA wall outlet charger doesn't deliver enough juice when Transmission is verifying files (CPU at 1150Mhz / ideal) to prevent the battery from being depleted in time.

On that moment the only option is to use the 1200(?)mA Nokia N900 wall outlet charger.
