It is not bad to charge from USB. The only thing is that a USB typically outputs a max of 500mA and the wall charger outputs 1200mA, so USB will charge a lot slower and if you are doing something with your N900 that uses a lot of power it may not even charge at all (it will tell you if it is not getting enough power to charge with). It is okay to leave it on while charging through USB, but will charge quicker if it is turned off.

Also bear in mind you won't be able to charge it from some USB ports (e.g.
a USB-socket-equipped keyboard, some front panel USB sockets of PC's which aren't allocated enough power, etc). Always charge it directly from a PC's back sockets (or a laptop's USB ports) to get access to full power. Phone can be on, no probs - just leave it alone as inkerby says.

I've left my charger somewhere and won't be able to get it for three days. Is it bad to charge my n900 fully from USB? Is it best for the phone to be on or off when I charge from USB?
Thanks,
Ian
