The rose gold iPhone 6S 32GB was introduced later than the 16GB and 64GB variants. The phone is better than the iPhone 6, which was brought out before the iPhone 6S. A refurbished iPhone 6S comes with an Apple A9 processor, making everything a lot quicker than the iPhone 6. The battery is also much better and the device has 3D Touch-technology. On the back, there is a 12 MP camera with dual LED flash for stunning photos and videos. On the front, there is a 5 MP camera for great selfies. If you don't need masses of storage, the 32GB will give you all the space you need.
