Apple iphone 6s plus is a nice featured phone.I seen it on my friends hands.It is high range phone.But the cost is higher than the features it have.My best suggestion is to reduce the cost or increase the features.The main thing I liked in 6s plus is processor speed and applications.The worst thing in this phone is sim.It supports single nano sim.Now all are using more than two sims.
I disliked its cost and sim availability and non removable battery.We cannot change the battery once it has got any destruction to the battery.And the battery capacity also very less.We are paying the money for metal used for its body.with the half of this iphone price, we can buy a good sony M5 mobile.The sony M5 mobilw is superb featured phone as per cost.
