The brand nameAPPLE speaks on its own.This iPhone 6s comes on two variants 6s and 6splus, size remains the same as 6 and 6 plus .It has a very good processor which makes it much faster than the other apple devices. Speaking of the camera it has an excellent camera where in u get a crisp photos and 2 new things is that u have
live photo option take a photo , open the image and press on the image for 2sec u can see the pic and the background coming live on screen which feels re living the moments and the other is the 3d touch wherein u have to just touch and hold the app icon for 2sec then options where u can choose the option from there itself and other thing is it doesn't work on all apps only a certain apps have this feature. This has come in a new colur called ROSE GOLD which is a Pinkish color with a golden touch on it also it comes in the colurs which apple has with all earlier phones. Coming on to the pricing its not pocket friendly becomes a dream like for a common people to buy.
Verdict: If have already a 6 or 6 plus I recommend not to go coz there only 2 features included and all remains same . If u have money to spend onn go for it.
