There is nothing new to celebrate about the iPhone 8S. It recycled from the trash and surplus inventory with zero innovation at $399
While it is a shame on the battery and camera front, it is an improvement over the 8 and it is cheaper. It's not meant to be their 'innovative' iPhone, thus the low key release.
Apple have done worse (ie the iPad Air 2 getting replaced with the iPad 9.7.. worse screen, thicker and not any faster) - at least this thing is faster and no worse than the 8
