Iphone 5s, Should you upgrade your iphone?

the new iPhone 5S has the same 4-inch screen and overall design as the iPhone 5 (which is discontinued) but has a completely new feature set.
The 5S name follows the standard iPhone convention of following up a numbered model with an improved “S” version.

In addition to the white and black (space grey, apparently) variants, there is also a new gold and white version.
New is that the iPhone 5s includes dual-band 802.11 a/b/g/n Wi-Fi (and you get the Bluetooth 4.0 also found in the old iPhone 5).

iPhone 5S processor and graphics

There’s a 64-bit Apple A7 chip on board with more than a billion transistors (32-bit and 64-bit apps are supported) It is an incredible 56 times as fast as the original iPhone and twice as fast as the iPhone 5.

The first-of-its-kind chip packs twice as many transistors in a piece of silicon roughly the same size as the A6 – 102mm squared.
iOS 7 will obviously support the 64-bit chip, too. A native 64-bit kernel, libraries and drivers are all part of the package.
The graphics, featuring OpenGL ES 3.0, are also twice as fast and Apple was keen to demonstrate the gaming prowess of the handset with Infinity Blade 3.

iPhone 5S battery life and LTE

As for battery life, the iPhone 5S will allow for 10 hours of 3G talk time, and 10 hours of LTE browsing. Indeed, the iPhone 5S is better at mobile browsing on LTE than on 3G – 10 hours versus eight. Now that’s a leap forward.

According to Apple, the 5S battery can manage up to 250 hours of standby time, 10 hours of talk time on 3G, 10 hours of internet, 10 hours of video or 40 hours of audio. Almost all of that is increased from what the iPhone 5 could manage.

iPhone 5S camera

The camera is a case of same resolution, bigger sensor with the 8 megapixel device featuring a f/2.2 five element Apple designed lens. Video is 1080p, while there’s 120fps 720p slow motion, too, plus a burst mode.

It can capture a 28MP panorama that adjusts exposure as a user pans their camera. There’s also a new True Tone flash that variably adjusts color and intensity for more than 1,000 combinations. Flesh will appear more natural – no more washed out profile pics? The sensor includes a 15% larger active area, and pixels (taking the bigger is better route) amount to 1.5 microns.

iPhone 5S Touch ID

Apple has also introduced a new fingerprint reader on the home button of the iPhone 5S. It scans sub-epidermal skin layers, scans at 500ppi and is, incredibly just 170 microns thick.

There is also 360-degree readability so you wont have to reorient your finger every time you want to access your phone. Thanks to the ring around the home button, it knows your finger is there and you don’t have to tell it to scan. It can even scan your print at whatever angle you press the button at. It’s also integrated with iOS 7.
