Considering I use my laptop as a desktop replacement (use my laptop more than my desktop, always have, even when I had a slower laptop than my desktop, the ease of use of a laptop is just good), it's usually always at my desk. If I do use the battery, it's usually just unplugging it and going out to the kitchen to get something to eat. That lasts maybe 30 minutes then I come back and plug it in again. Other than that, it's plugged in at my desk.
