I have a 6s Plus and if I turn the screen brightness up full, I can literally watch the battery % drop every couple of seconds...,(reply>), Magics That is not true, at all. Much like upgrading pieces of a PC, when you put a new part in, such as a graphics card that is better, it is going to draw more power. The same can be said for software updates.
