Microsoft is heading in a good direction. I do like Surface 3 and 3 Pro. But the battery life of Windows laptops (including Surface) is still not good enough. We have to admit Apple does well in Macbook's battery life.
If you're looking for battery life, it'd be worth it to look into the thinkpad x250. It claims to have a 20 hour charge, and real world tests [0] stand by that claim.
