Now how many people turn their BBs off and charge them is another question. I had to power mine down to test this.
Somewhat off topic but it will definitely speed up the charge with the phone off however. I personally use a generic external charger with a high mAh output. I can usually charge from 15%-100% in about one hour. Another option was to use the Blackberry premium charger (like for the Playbook) which has a higher mAh output too.
Rambo-> How do you set up the chime alert? Just curious.
