To be honest Apple iphone 6s plus is great device from another handset in market.
The speed and performance of 6s plus is best from others. features of 6s is adorable.
The 3D touch is be a great to use and live photo from 6s is also be great feature. Apple A9 chip performance is great. Iam using 6s from 11 months variant of 128 gb rose gold. I have notice its speed and accuracy very closely which make 6s best deal for me. The front and back camera is so clear and focused.
The Battery backup is what wich make 6s and 6s plus all time best Device from Apple. but if we look 6s plus display size from its brother 6s it will liltel bit to hard to handel in pockets. In the end it would be best device on earth these days!
