Apple's flagship iPhone has been updated and upgraded bringing with it a new design, new features, and new excitement. With the rest of the year's smartphones laid out - except the next Nexus - this is the time for the iPhone to reassert itself against competition that's stronger than ever.

Design; build quality; 4.7-inch screen; faster processor; Apple Pay; iOS 8; camera

No wireless charging; no waterproofing; battery still not great

Apple's change to its juggernaut smartphone is here, and it's not just a number change with a fingerprint sensor. This time, the iPhone includes a bigger screen, faster processor, and a new design.

A bigger iPhone; yay; Built beautifully; almost like the iPod Touch as a phone; Reachability (double-tap home) is a neat idea for larger phones; Fast 4G speeds; Finally; 802.11ac is here; Excellent rear camera; iOS 8 now lets you exchange and replace keyboards; With Mac OS X 10.10 "Yosemite," you...

Screen is larger; but not really a huge improvement; Fixed storage with no way of upgrading; Expensive; Slippery; Hand-hold for thumb at the bottom is a bit of a balancing act with a phone this size; NFC can't be used with pretty much anything; Quite a few iOS 8 bugs; Mediocre battery life

Apple's got a brand new bag, but battery life isn't in it.

It is very good experience to buy iPhone 6. Next time please provide me some special offer.

Very good, Item sent as expected and very quickly

None of our other top unlocked phones are the iPhone's hand-friendly, 2.64-inch-wide size. And none of these phones have a camera as good as the iPhone's. But the real reason to spring for an unlocked iPhone 6 isn't hardware, but software and support.

Universal carrier compatibility in the United States; Best third-party apps of any mobile OS; Excellent low-light camera performance; Fast Wi-Fi

Phone calling performance is just okay

This phone does not disappoint. It may be pricey but it is hella fun to use. 8 MP camera seems a bit small for a current-gen smartphone, but it shoots quite well. The phone looks very neat, with aluminium built to give it a touch of class. After all, it's an iPhone.

-Camera is quite pleasing; -Siri is fun; -Easy to use; -Looks classy; -Touch ID; -An Apple product; -Lots of apps

-Display quality is a quite low compared to other newer smartphones; -Battery life is quite poor; -Pricey; -Microphone jack located at the bottom

Just got this iPhone 6 Space Grey 64gb smartphone. What an incredible device. After two weeks of using this I am happy it's the best phone I've had as regards size of screen, user friendliness , overall mobile experience.

It wouldn't be a complete smartphone test without the current-generation iPhone - Apple continues to be the best-selling smartphone manufacturer on the market (although Samsung is close behind). The iPhone 6 has embraced the "growing" trend, featuring a larger screen than most other Apple models.

Great-looking display; Camera is very easy to use; Device is easy to use overall; Can run more demanding apps and games

If you are an iPhone user, and you specifically want an iPhone to be your next smartphone, the iPhone 6 is great, but of course the iPhone 6s is even better. It's going to come down to budget ultimately, as the iPhone 6 is a brilliant iPhone that'll save you a few pennies if you're set on getting an...
