Days after Apple iPhone 5S release, the iPhone 5 upgrade is what users are speculating.

The Cupertino Calif.-based firm rolled out the iPhone 5S with excess of technical advantages and latest updates that has been provocative in making the device a ruler.

With the iPhone 5S, what’s updated sits on the inside. With enhanced iSight camera, Fingerprint scanner and faster chip, the iPhone 5 upgarde does look like worth a climb. What goes for a toss is the weight and screen size, which is same as its predecessor; the iPhone 5.

Though the 8-megapixel camera is same in both the devices, the iPhone 5S does hold larger pixels and dual flash mode with improved light sensitivity.

Another new feature is the slow-motion video shoot mode on the iPhone 5S, which the iPhone 5 lacks. The former device can also capture 10 photos per second.

Loaded with the A7 processor and iOS 7, the device can boost faster as compared to the iPhone 5’s A6 and iOS 6.

Considering all these updated features and faster 4G LTE speeds, the iPhone 5S does sound like a fascinating device, set to walk on the path of success.

Slated for 20th September release, the smartphone will be out for grabs in a choice of silver, gray and gold color.
