If you are going to buy a new iPhone, this is the one to get - there’s slightly longer battery life, a better camera, fast innards and protection against water. However, many of the changes are slight, but still it is a better choice to iPhone 6s. The upgrades of the internal memory are quite appreciable. The camera is probably the biggest hardware upgrade in terms of its low light capability. The iPhone 7 isn’t a huge upgrade; it’s a few small - but useful - step forward.
