Iphone 6s actually looks very similar to Iphone 6. Iphone 6s is slightly heavier but if feels really good in hand. The touch is really awesome. Sad thing is that it does not support third party apps. In terms of performance Iphone 6s is really very impressive. 4k video recording is really good.
Gaming experience is excellent, no lags at all. I hope it supports fast charging soon and also the storage of the phone should be increased.
