Hey guys, I'm coming from Android. I've never used an iPhone so I'm new to that "usage time" concept. On my Note 4, I got about 5-6 hours screen on time. This doesn't include music in the background, for example. On my iPhone 6, I got about 9-10 usage time. This also include usage like music, GPS tracking, etc. How much "screen on time" that I should expect on my iPhone 6?
