It's 76Wh in 2016 vs 99Wh in 2015 -- a 24% smaller battery. To have the same battery time, it must draw 24% less current than it did with the 2015 model.
Secondly, we should always compare watts instead of amps unless we know the batteries have the exact same voltages.
For example, for a battery life of 18h it must draw 4.2W on average (76Wh/18h). I don't think that's possible because only the 2016 MacBook uses that little power -- 4.1W (41Wh/10h).
