Battery life depends not only on battery size, but on a number of other variables. Of course, battery life measurement is complex and varies greatly depending on how you use your phone. For OLEDs, every single pixel point is important, and if you look at a picture with lots of white dots, you'll drain more than one dark-colored image because each single pixel consumes energy there, unlike the entire LCD backlight. Affects the battery, and the number of applications running in the background.
