The iPhone 6s comes with iOS 9.x operating system, and Xiaomi Redmi Note 4 counts with Android 7.0 Nougat operating system.
The Apple iPhone 6s has a bit better looking display than Xiaomi Redmi Note 4, because although it has a way worse 1334 x 750 resolution, a little bit lower quantity of pixels per display inch and a bit smaller display, it also counts with a little bit brighter display. IPhone 6s features a little faster CPU than Xiaomi Redmi Note 4, because although it has less RAM memory and 6 lesser and slower processing cores, it also counts with a 64 bits processor and an extra GPU.
IPhone 6s has a bit more memory capacity to install games and applications than Xiaomi Redmi Note 4, because although it has no slot for external memory cards, it also counts with 128 GB internal storage. The Xiaomi Redmi Note 4 features a superior battery duration than iPhone 6s, because it has a 4100mAh battery size instead of 1715mAh.
The Apple iPhone 6s features just a bit better camera than Xiaomi Redmi Note 4, because although it has a smaller diafragm aperture which is not so good for low-light photos and a less megapixels camera, it also counts with a much better (4K) video definition.
Although iPhone 6s is a better device, it costs a lot more than the Xiaomi Redmi Note 4, and it doesn't have such a good quality/price relation as the Xiaomi Redmi Note 4. So if you need that extra features and specs, you can buy iPhone 6s, otherwise you can save a couple dollars and buy the Xiaomi Redmi Note 4, resigning a couple features and specifications.
