It seems to me like Apple almost wants you to charge your phone almost daily... I do not know... I do not see the reason for them too keep slimming their phones when it noticeably affects the battery. I kinda dislike their attitude. Expected to do the same as they did with laptops, for example, where MacBook Pro came so light and thin that I was like, it's a little heavier than Air and a little thicker, but hell it works better! They didn't sacrifice anything at brought amazing performances both in terms of raw computational power and battery life. What bugs me is that iPhone SE got thinner... WHY?! Why Apple didn't fill that space that saved by battery... Nobody would say, HEY CHANGE IT! Never enough battery power
