Part of the 8th generation of iPhones, the iPhone 6 was announced alongside the iPhone 6 Plus on September 9th 2014. Once the flagship of Apple’s iPhone fleet, today we’re going to be taking a look back at the iPhone 6, delving into the improvements it benefitted from compared to its predecessor. As is usually the case with iPhones, this product has aged exceptionally well, and has stood the test of time to be a feasible alternative to many of the modern day middle-market smartphones. Welcome to our iPhone 6 Review.


iPhone 6 Review 2021

Co-flagship with its sibling device, the mobile phone market of 2014 was taken by storm when the iPhone 6 was released alongside the iPhone 6 Plus. Introduced to us under the slogan “The Two and Only”, these two products were once the greatest iPhones to date. In this review, we will be delving into what sets the 8th generation of iPhone products apart from those that came before.



The iPhone 6 succeeded the iPhone 5S as flagship of Apple’s mobile empire. Comparing the designs of the two we see a radical change, something Apple is often criticised for not implementing in other generations of the iPhone.

The 5S featured a 4-inch screen. With the iPhone 6’s screen measuring in at 4.7-inches screen, the 8th generation of iPhones benefit from a much larger screen. Already a slim smartphone, the iPhone 5S is beaten still in this regard, with the iPhone 6 a whole 0.7mm slimmer than the 5S.

The iPhone 6 is also more rounded at the corners, giving it a smoother appearance. A noticeable adjustment that may seem trivial, was the moving of the lock screen button from the top of the device to the side, where it has remained until present. This is easily one of the best design decisions made by Apple in their design of the iPhone 6.

However, the iPhone 6 actually weighs more than its predecessor. This may be due in part to its larger screen size, weighing in at 129g. When compared to the compared to the iPhone 5S’s 112g, the iPhone 6 does seem quite heavy in your hand.

While the iPhone 5S remains one of the most attractive smartphones we’ve come across, even still the iPhone 6 improves on its predecessor immensely when it comes to design. With a full aluminium chassis, the matte-like metallic finish gives the iPhone 6 an aura of class and refinement. Thinner, smoother, sleeker, this design would become the new iconic iPhone design. In fact, the iPhone 6 was so aesthetically pleasing, that its design became the template for future iPhone designs for years, with traces of its features in every iPhone all the way up until the iPhone X.

Colour choices for both devices were the same, Space Grey, Silver, and Gold.



The iPhone 6 runs on the A8 processor, which is slightly more powerful than the A7, which was used in the previous generation. Apple claimed a 25% boost on CPU, and 50% graphics performance boost between the two generations. Furthermore, the touch-ID on the 6 is much quicker than it ever was on the 5S. If you’re unfamiliar with the touch-ID feature, it allows your iPhone to scan your fingerprint, and unlock when it identifies the owners fingerprint. This is an exceptionally useful feature, as it’s quick and convenient for people on the go.

As usual, general speed improvements were made to the iPhone 6, with actions as basic as exiting in and out of differing menus and apps being executed much faster on the iPhone 6. The M8 Co-processor in the iPhone 6 is also far more energy efficient than its predecessor. As well as this, a barometer is included in the 8th generation iPhones, meaning that 8th generation iPhones are able to detect altitude.

Another advantage the iPhone 6 has over the 5S is better 4G, and Wi-Fi connectivity, making web browsing a breeze.

General Improvements

No iPhone 6 Review would be complete without breaking down the general improvements that came with the eighth generation. iOS 8 brought with it many different features. One of such changes moving widgets from the home screen, to the notifications centre. This was a swipe to the left from the lock screen, and contained all notifications and news of interested to you, which was immensely useful as now users didn’t have to unlock their device to retrieve information from their feed.

A change that we particularly enjoyed was the move towards interactive notifications. In other words, now you could respond to messages, texts, and more, by dragging down on banner notifications. This made responding to notifications infinitely more convenient.

Another significant change in iOS 8 was Apple finally easing up about the keyboard. For the first time, you could select what kind of keyboard you wanted to use on your iPhone. Furthermore, the iPhone’s keyboard was upgraded so that it then would display predicted words above the keys, which you could simply press for faster texting. Paying attention to how the user speaks, the iPhone would begin suggesting word and phrases that they would use often, to provide them with a quicker, more convenient way of typing on their iPhone.

Further optimising how we communicate with one another, in this generation of iPhone, audio messages were introduced, which were small soundbites you would record through your iPhone mic, and send as if they were text messages. The receiver on the other side would then be able to press play on the audio file.

Another feature we certainly enjoyed that was introduced on the iPhone 6 was the ability to track which applications were draining the most battery from your iPhone. This feature was especially useful for users who like to multi-task. When jumping in between several applications, it’s easy to forget which apps you have open all at once. The result can sometimes mean that you may have a large number of apps draining power in the background that you are unaware of, which will deplete your battery life significantly.


Apple Pay & “Hey Siri”

Finally, two more features we would like to bring up, ‘Apple Pay’ and ‘Hey Siri’ were introduced in this generation of iPhone. Finally adding NFC to their mobile devices, Apple Pay allows the user to pay for goods and services wirelessly using contact-less technology and touch-ID. “Hey Siri” was a useful upgrade to the immensely popular Siri function of iPhones. The virtual assistant was upgraded so that the user could essentially plug in their iPhone, and summon Siri simply by uttering the words ‘Hey Siri’.



All factors considered, there is a sizeable degree of improvement between the iPhone 5S and the iPhone 6. Ushering in the 8th generation of iPhones, The 6 is bigger, better, faster, and stronger, all the while looking incredible. It’s clear that Apple pulled out all the stops for this specific regeneration of the iPhone, as both functionality and design were overhauled.

Yes, we concede that the iPhone 6 was slightly heavier than its predecessor, but for all the added features we believe that a weight compromise is more than fair.

Retrospectively speaking, the design of this iPhone was so impactful that it extended beyond the iPhone 6, with several generations of iPhones succeeding it having designs based on the 6’s blueprint. Arguably, we would not see Apple alter the design of their iPhones in such a drastic way again, until the introduction of the iPhone X.
