So it’s around 6 hours, subtract an hour if usage is heavier and add 1-2 hours of usage is lighter and you get more or less the same battery life range as the rest of the 4.7-inch iPhones on their original versions. Seems like the A13, when coupled with iOS 13 doesn’t make a whole lot of difference when you compare it to, say, the A10 on iOS 10.
I don’t think people can be too annoyed at this, you won’t get more battery life out of a 4.7-inch iPhone. If you need more battery life than this you need a different iPhone. Anyway, looking forward to more results, to see if my assumption remains correct.
