Sorry I wasn't clear -- I always plug it in when I'm at my desk, and I'm hardly ever away from my desk for more than 4-5 hours. So I know it works that long at least. Past that... I mean I haven't deliberately not plugged it in just to test... I got through a movie and a handful of Rick and Morty episodes while on a flight... Drove home from the airport late so I just went to sleep... hit the "Lower Power Mode" warning as soon as I opened it the next day. It wasn't plugged in that night... Battery life seems reasonable. It doesn't seem amazingly better than my old MBP.
