Unquestionably, the standout features of the iPhone 5s are its newest hardware inclusions and upgrades, namely Touch ID, the M7 motion co-processor, 64-bit architecture and the all-new iSight camera. These are not only what differentiate it from the previous iPhone 5, but justify its place as the flagship iPhone when compared to the iPhone 5c.
Now, fingerprint scanning is a pretty boring subject and our only real day-to-day experience of using the technology is with those digit readers built into laptops – a slide-to-unlock affair that worked 60% of the time.
Introduced to replace passcode authentication for unlocking the phone and making iTunes purchases, Touch ID is a joy to use. The sensor is built right into the Home button and registration of a thumb, finger or both – five digits can be registered – takes about a minute using a most-pleasing enrolment system.
Once recorded, Touch ID has 360-degree, readability of registered digits, meaning it’ll unlock your phone no matter what way up you’re holding the handset. The key selling point, however, is the simplicity and speed of identification.

Performance and Battery Life
The iPhone 5S is the first widely available smartphone to be powered by a chip that features 64-bit architecture. Apple also claims that its A7 chip delivers CPU and graphics performance up to two times faster than its predecessor. We’d like to clarify that the speed bump is not related to the processor being 64-bit. Though it lays the foundation of the future; the 64-bit architecture will help in better memory management and will work in tandem with apps optimized for it as they’re made available. It also supports OpenGL ES 3.0 standard for enhanced graphics performance especially while playing 3D games.
Apple promises improved battery backup with the iPhone 5S. While the standby time delivered is indeed better than the iPhone 5, the phone will still last you less than a day with moderate to heavy usage on a 3G network. After full charge, the battery lasted around nine hours with moderate to heavy use.
The iPhone 5S runs iOS 7, the latest iteration of Apple’s mobile operating system. According to Apple it’s the most significant iOS update since the original iPhone. It brings an overhauled user interface design including new icons, native apps and a number of new features.
When you unlock the screen, you’ll see that the home screen features a new Parallax Motion effect, making the background wallpaper shift by utilizing the iPhone’s accelerometer, giving an appearance of depth. The interface has been stripped off skeuomorphic elements like leather and felt, and bevelled buttons, that have been replaced by flat shapes and gradients, and text. A new ‘swipe to right’ gesture has also been introduced to go back, one step, while navigating an app.
Apple has never believed in running the megapixel count race and has instead focused on delivering a usable camera that takes quality pictures, consistently. The iPhone 5 camera is still one of the best in the market, and the iPhone 5S camera takes the experience to the next level.
The camera on the iPhone 5S offers a 15% larger sensor, bigger pixels and an f/2.2 aperture to allow more light to come in. The improved optics result in much better low-light pictures compared to the ones shot with an iPhone 5. The level of noise and distortion while capturing lit objects in low-light conditions, is much lower in pictures taken with the iPhone 5S. We also found colour reproduction to be more accurate, and white balance to be in perfect harmony, thanks to the new image signal processor, part of the phone’s A7 chip.
Images taken in daylight and indoor light turned out to be excellent, placing the iPhone 5S camera in the league of the best camera phones available in the market. There was no shutter lag or focus issues.
