Everything we know about the iPhone 6S so far

It's almost September, which means we might just be weeks away from learning about Apple's next iPhone.

Although we don't know anything concrete yet, various leaks and notes from analysts have painted a picture of what we might be able to expect from the successor to the iPhone 6 and 6 Plus.

Based on what we've heard, it sounds as if the changes will focus more on enhancing existing features such as the iPhone's screen and camera rather than a total redesign.
