Actually, I can do better :P. I can put a slice on the bottum (an extra 9 cells). Then it runs for 2 days (including leaving it suspended overnight) without charging. I can take my laptop, leave my charger at home, go to uni, stay at a friends house, go back to uni for another day without a problem :). I'm curious how much I can squeeze out if I tune it. I didn't expect it to be this energy efficient, so I thought I'd need the slice to avoid charging at uni (can be a pain to get to a powerpoint). I thought my customisations would hurt it's power consumption more.
