Conclusion: The iPhone 5S is an essential purchase if you can afford it, and don’t already own the 5. Although there is a lot to differentiate the 5S from the 5, I’d hold back until the iPhone 6. For newcomers, the 5S will absolutely blow you away. There’s nothing to hate on, just lots to love.
Summary: Fall is Apple season. One year after the iPhone 5, Apple releases its direct successor, the iPhone 5s. In terms of looks, this is not much more than a mere cosmetic update - the 4-inch IPS display and the chassis remain unchanged. There is only one notable exception, as the new home button now ships with a fingerprint sensor.
Pros: Great performance, 64-bit architecture, Bright, colorful, naturally looking Retina display, Long battery life, Superb build quality, premium materials, Good EarPods (included), Surprisingly precise GPS module, Low emission and power consumption levels, The superb build quality and the premium materials used. The snappy A7 SoC. The intuitive new OS.
Cons: Poor black levels, poor contrast ratio, Resolution could be better, screen size could be larger, Non-extendable internal storage, Expensive, As always, a micro SD slot and an HDMI port (the latter can only be had via an expensive adapter). An improved display resolution.
Summary: With an identical design to its predecessor, and the same software you can now get on most iPhones, the iPhone 5S doesn't really offer enough to justify upgrading from the iPhone 5. If you're on older iPhones though -- or you're looking to take your first steps into Apple's world -- its astonishing power, excellent camera and fingerprint scanner make it a great option to consider.
Cons: Very expensive; Identical design to iPhone 5 might disappoint those looking to upgrade; No removable battery or expandable storage; Display remains same size and resolution.
Summary: The Apple iPhone 5s is the phone we expected, if nothing else. It’s more powerful than ever, with a better battery life, all inside the same slick design. If you’re toting an iPhone 4 at the end of its contract and a truly fantastic camera matters to you above all else, it’s a no-brainer, but if you’re tired of glass and gun metal grey and want a new experience however, the colourful 5c might be the better option.
Summary: Per usual with these "S" revisions, the iPhone 5s is an overall improvement over an already great smartphone. But with fierce competition from the HTC One, Samsung Galaxy S4, and the Nokia 1020, the iPhone is a tough sell to those looking for a bigger screen, flexible operating system, and a new design.
In fact, users that value these features should look elsewhere entirely.
Pros: Touch ID is very well executed, Impressive camera, Excellent performance, Still the easiest smartphone to use
Cons: No real design upgrade, Still waiting for a bigger screen, iOS7 is still playing catch-up, No real improvement to battery life
Excerpt: I pull my iPhone out of my pocket, tap the home button, and let my thumb linger an extra second longer than I normally would have. The lock screen fades away and the iOS 7 home screen zooms into view, each icon landing neatly on the display. It’s an instinctive gesture iPhone owners have been doing for the better part of six years, and yet it still feels like magic: I just unlocked my phone with my thumb.
Conclusion: Since the early adopters have snapped up the entire initial inventory, you don't need to make a decision quite yet. If you don't have an iPhone 5 or another 4G LTE-capable smartphone, getting a faster data connection ought to be your prime reason for getting either the 5S or the less expensive non-fingerprint-reading 5C.
Summary: From its fast A7 processor and fingerprint scanner to its intriguing motion-sensing M7 coprocessor,the iPhone 5s is a smartphone that both users and developers can grow into. It's practically future proof. We say practically because you can't stretch the corners of this phone to enlarge the display. Some shoppers will simply pick devices like the Galaxy S4 and HTC One because they have a bigger canvas.
Pros: Excellent camera and flash, Lightning fast A7 processor, Fingerprint sensor works well, Solid and elegant design in new colors, Bright display
Cons: Relatively small screen, Below-average battery life, Limited camera features
Excerpt: To be honest I was never a fan of the original iPhone 5 - when it was launched last year - as I felt the iOS 6 platform at the time did not suite the new screen size/dimensions (everything looked stretched or elongated, not to mention the number of apps which had an unattractive gap).
