From 2015 to 2016 models the battery capacity dropped from 74 watt hours to 49 watt hours in the new 13" design. The gap was made up for by efficiency gains of the CPU and possibly the display. But the display can also be cranked way brighter now, running it at the full 500 nits will hurt your battery performance for sure. Also if you are running demanding loads it will be worse off as well.
The Touch Bar likely sips power, but the real issue with it is the lost battery capacity beneath it (The non-touchbar models have larger batteries at 54 watt hours)
