I bought the iPhone 6s 16GB variant for 45k inr around 8 months ago on Flipkart.com. Here are some key points which I would like to cover about this phone-
Design and Finishing- The metallic body is just premium. The glossy back finish gives a shiny look.
Storage and Ram- 16GB variant wont be enough if store everything on your device. Nevertheless, 6s is still available in 32GB, 64GB and 128GB.
Operating system- My device came with 9.3.2 but is upgradable upto tge latest iOS10.
Additional features( relative to the previous iPhones) - Enhanced Apple A9 chipset with 64-bit architecture. The 4.7 inch LED display provides 3D pressure touch.
The device has been working great since the day of purchase. Its a bit overpriced but still worth the money. In case youre planning on buying an iPhone, I would definitely recommend 6s over the latest 7 edition.
