 CAMERA


A 12-megapixel camera is a huge jump for Apple, which has been holding onto its 8-megapixel sensors in its iPhone for years. Autofocus will pick up the pace, according to Apple, and color accuracy is a point of pride.( True Tone Flash, autofocus, IR filter, Burst mode, 4K HD video recording (30 fps), Slow-motion video (1080p 120 fps or 720p 240 fps), Timelapse, Panorama, Facial recognition)
The 5-megapixel front-facing camera (Exposure control, Face detection, Auto-HDR, Retina Flash) now brings the iPhone 6S on par with a lot of today's competing handsets. Of course, it includes the company's proprietary voice chat feature, FaceTime video. Here's something wildly different, though. Instead of including a dedicated flash for the front-facing camera, which only a few phones do, Ap
ple is using the home screen to light up instead. This is meant to increase the brightness of those selfies even in low-light situations.
A few test selfies taken in the demo rooms looked really good, with crisper, richer color and details than previous iPhones.
 Apple also joins rival phone makers in including 4K video recording, at 3,840x2,160-pixel resolution. You'll be able to take 8-megapixel camera photos while recording at this ultrahigh resolution. (The immediate benefit of shooting 4K video would be watching them later on a 4K TV.)

TOUCH
The biggest, and most noticeable change to this year's set of phones is "3D Touch," a pressure-sensitive display technology that lets you push in to do new things on your phone. After getting a chance to check out the new iPhone 6S and 6S Plus briefly at Apple's San Francisco event, these were our impressions.
 Touch ID: The second-generation sensor promises to snap open the phone faster than before. Hopefully fingerprint authentication will also speed up.
Security: A highly advanced fingerprint sensor that’s now faster and better than ever, Touch ID makes unlocking your phone easy and secure. And it lets you use Apple Pay at over a million stores and within participating apps.

PROCESSOR

Under the hood, we have an upgraded, proprietary A9 processor that continues Apple's theme of mystery when it comes to exactly what's going on in there. Though it's impossible to appreciate during our quick demo, what we do know is that this is Apple's third-generation 64-bit chip. Apple claims that the A9 is 70 percent faster than last year's A8 when it comes to the usual computing tasks (like opening an app, for example), and 90 percent faster at graphical tasks, like gaming.

COVERAGE

(Faster 4G LTE, Wi-Fi connections) Apple says it'll have the fastest forms of LTE Advanced, if that's supported where you live, and will also include support for the latest, greatest Wi-Fi networks. 

DIMESION

Visually, it’s going to be a case of meet-the-new-boss: the 6S will be a hair thicker than its predecessor, but not enough that you can tell the difference with a pair of calipers. Otherwise, it’s the same rounded edges, buttons, and 4.7-inch screen that you can find on the iPhone 6. (source: Gizmodo.com)
