I both work more and work less from home.
I work more intensively, I set the timer and blitz whatever I'm doing in the mornings so I've done four or so really good hours by lunch. No chatting, no walking places, no commute. This bit is definitely more than when I go into the office, I do still have an office.
In the afternoons, I often do less- sometimes I don't work all afternoon, but do a couple of hours in the evening. I work one weekend morning without fail every week. I even work late at night if I can't sleep for an hour or so. This bit is more faffy and 'less' by 5pm than if I were sat in an office trying to stay awake, but gets the right amount of work done.
I have tight deadlines and long-term deadlines (academic/writer) so if nothing gets done, students would put in complaints, and I wouldn't get promoted or even worse, would attract a warning/disciplinary issues. So, I love the freedom to take the afternoon off, knowing that means Sat and Sun morning this week I can work.
It's better as you can work more when you are more effective (mornings obviously for me) and slack off at a time when you are less effective anyway (afternoons). I do crap like sort my emails about 3.30-4pm as I am good for nothing by then anyway.
