I have been using iphone 6s for mor than a month and I must say it is the best smartphone from apple. Though it is quiet expensive but I love the design and looks. It was very easy to use.The best feature of the device is that has no Lag or stutter at all.The interface is smooth and Faster.The battery backup is awesome, when the phone is not in heavy use the battery rarely reduces. It provide super fast finger print sensor.The device can be used in the sunshine also as its outdoor brightness is great.I would advice everyone to try the phone.
