Apple introduced two new iPhones last year: The iPhone 5S and the iPhone 5C. While the 5S was its new flagship phone and had updated internals and externals, the 5C merely received any updates other than the new plastic body and a slightly updated camera. Nonetheless , Apple introduced many exciting features with the iPhone 5S which made the best phone even better!
Processor
The iPhone 5S is powered by the world's first 64 bit processor, the A7 (dual core clocked at 1.3 GHZ) along the Motion M7 coprocessor. Apple claims that the A7 is 2X faster than the A6. The A7 is very very fast and you won't notice any lag at all. Applications open in a snap and game load times have reduced. Playing Infinity 3 on iPhone 5S amazed me. Those graphics, those shadows were just damn good. The game didn't lag at all and response time was great too! The game felt like a console quality game, especially when playing it on the iPhone 5S. The updated PowerVR GPU now supports Open GL/ES 3.0.
Camera
The 8 MP iSight camera now has larger pixels (1.5µ) with five element lens, f/2.2 aperture, Auto focus, Tap to focus, Geo tagging ,Panorama(and other common features) and what sits besides the camera is a true tone (dual LED) flash. The camera captures amazing photos as usual and supports slo mo(slow motion@120 fps) video@720p as well as full HD 1080p @30 fps. It's really cool to watch your epic basketball shot in slow motion ( believe me, it is).Low light photos have good color reproduction (thanks to the true tone flash).The photos are crisper and have more detail. The front camera is a 1.2 MP with 720p HD video support.
Touch ID
This is the main feature that Apple is proud of. The iPhone 5S' home button is not just an ordinary button, but a fingerprint scanner that Apple is calling, the Touch ID. The user simply places his finger or thumb on the home button and voila! the iPhone is unlocked! Isn't it amazing? It's pretty easy to setup and simple to use. And once you start using it, you won't feel comfortable with those old pattern/passcode locks.
Other Specs
Other features include a 4 inch IPS 1136x640 display with a pixel density of 326 ppi(same as the iPhone 5), 1 GB RAM, Wifi 802.11 a/b/g/n , Bluetooth v4.0, GPS with GLONASS, proximity sensor, ambient light sensor, compass, accelerometer and three axis gyroscope.The iPhone 5S comes with iOS 7. It supports 2G/3G/4G LTE and Apple promises battery backup of Talk time: up to 10 hours on 3G
Standby time: up to 250 hours
Internet use: up to 8 hours on 3G, up to 10 hours
on LTE, up to 10 hours on Wi‑Fi

The iPhone 5S comes in 16GB/32GB/64GB and retails at Rs. 52366/Rs. 62450/ coming soon respectively. Color options include Gold, Silver and Space Gray.
Pros
World's first desktop class 64 bit A7 processor, Slow Motion video capture, amazing camera, Touch ID, iOS 7.
Cons
A 4.5 inch screen would've appealed to a wider audience, Full HD display is the standard but Apple stayed at 1136x640, Expensive.
Verdict
Apple just made their best phone even better. Touch ID is appealing and the 64 A7 has a lot of advantages (though there aren't many apps that make use of its potential yet). But Apple has started to loose that INNOVATION, and we expect it does something incredible with the next iPhone. But this iPhone is incredibly great with all that potential waiting to be exploited. Go for it if you have the money, you definitely won't regret buying the best Apple product yet.
