IPhone one of the most premium phones all the time.But this time iphone 6s.Design pretty similar to its precider iphone 6 but on CPU per formance it is 25-30% greater than its precider having A9 chipset by nvidia.I appreciate the work what apple is doing, instead of having 8 cores or something which drains lot of battery and device gets heat up apple makes devices having two cores which is more efficient.GPU performance is to the peak this device can load games faster than any other devices out their market.The camera is also pretty good.If u are looking for a device for handy this is one of the device you can get in the market.Inspite of having 2 gb of ram this device is brilliant in keeping all the apps running in background. Few things I do not like in this device- 1) Poor display, the display is not great when compared to other devices in the market right now. 2) Less battery capacity, though having 2 cores this device dont drain battery much but the battery capacity is to less than compared to drainage with 1710 mah
