I have been using iPhone 6s from the last 3 months and it is the best smartphone I have ever used.The device never lags, hang or have heating issue.The camera quality is awesome.The device is handy and attractive. It supports all high end games beacuse of this processor and ram.The battery backup is great as it last more than 2 day.It provide finger print scanner which is very good.I would recommend everyone to buy the device if they can afford the high price.
