It may be a near-identical twin of the iPhone 5, but the iPhone 5S is a major upgrade. It may be a near-identical twin of the iPhone 5, but the iPhone 5S is a major upgrade.
SummaryiPhone 5s makes cutting-edge fingerprint technology easy to use.

is stored on the device and not online. It can only be used to unlock the phone and while installing apps. The technology is exciting and would be even more useful if the fingerprint could be used to lock apps such as WhatsApp or Dropbox, where users store private data.


The iPhone 5s houses Apples A7 processor, which is twice as powerful as its predecessor (A6). The phone also has a motion co-processor called M7. This chip can collate data from the compass, gyroscope, accelerometer, and other sensors. M7 helps iPhone 5s check movement, speed and direction without draining battery life. A simple use is illustrated by a fitness app called Nike+Move, which tracks movement and speed during workouts. More advanced use could involve integration with navigation apps, where users are warned if they exceed speed limits, etc.

The iPhone 5s feels just as fast as the 5c and 5, but the true power of the processor can only be judged after more apps are designed for the A7.

All these improvements are like buds they will bloom in the future. But if the iPhone 5s has one flower in full bloom, it has to be the camera. Although it retains the same megapixel count (8), the iPhone 5s camera marks a major improvement over its predecessor. The pictures are sharp and there is no time lag between shots. What it lacks in resolution, it more than makes up for in terms of quality and speed. Low-light performance is very good and colours were reproduced accurately most of the time. Many users will find the burst mode useful. It lets you capture 10 pictures, select the best frame and delete the rest in just three clicks.

The phone ran out of charge after a days use (30-odd calls, 200+ messages, five hours of reading ebooks, browsing, social networks and an hour of streaming music over wi-fi).

Should You Buy It?

Yes, if you have Rs 53,500 to spare. Some may not like its size, but the iPhone 5s is a powerful phone, thanks to flawless performance, an amazing fingerprint sensor and a really good camera.
