Iphone 6s
The hardware design of iPhone 6S is nearly identical to that of iPhone 6, although the chassis is now made of a stronger aluminum first used by the Apple Watch Sport to improve its rigidity.[13] It is available in gold, silver, space gray, and new for the 6S, rose gold-color finishes.[19] iPhone 6S is powered by the Apple A9 system on a chip, which the company stated is up to 70% faster than Apple A8, and has up to 90% better graphics performance.[19] iPhone 6S has 2 GB of RAM, more than any previous iPhone,[5] and also supports LTE Advanced.[13] While the capacities of their batteries are slightly lower, Apple rates iPhone 6S and 6S Plus as having the same average battery life as their respective predecessors.[20] Although the device is not promoted as such, the iPhone 6S has a degree of water resistance due to a change to its internal design, which places a silicone seal around components of the logic board to prevent them from being shorted by accidental exposure to water.[21] Thei
