I was getting 10 minutes but i was using two 3s 2200mAh batteries, which are too heavy for serious 3D work.
Bottom line is you will get similar flight time to what you could expect from a 4s battery of the same total weight as your 6s battery.. there is no free lunch.
A 6s 1600mAh battery will weigh the same as a 4s 2400mAh (1600 x 6/4 = 2400), and you would expect similar flight time, maybe a shade more on the 6s due to better efficiency but no major difference.
