I think no phone can beat the Z3 for battery life, the S6 and M9 also suffer from a not so good battery, that's why I bought a quick charger from US for my car and one for my home (they barely cost 10$ there), it looks like 5.01 and 5.0.2 the culprit, the incoming Android M update will boost battery but if they will release it in September it will take till Christmas to get the proper update by samsung and HTC.
Better get a quick charger for your car then ;)
Well I think android 5.1 fixed it so it should be good before android M!
However I think my note 4 won't see android 5.1 before august and I bet it won't see android M before next february!
I'm actually surprised by your great optimism and faith in samsung's update timeline!
