FAQ’S

What are all the differences between the iPhone 6 and iPhone 6 Plus and the earlier iPhone 5, iPhone 5c, and iPhone 5s? Which is the best for me?
With even a quick glance at the discontinued iPhone 5 or still current iPhone 5c and iPhone 5s compared to the subsequently introduced iPhone 6 and iPhone 6 Plus, it is obvious that the iPhone 6 and iPhone 6 Plus are substantially larger and pack much larger displays.


This immediate observation is correct, but there are many other differences that are also useful to evaluate in detail. It also is worth noting that there actually are a whopping twenty nine different models in these lines — five iPhone 5 models, eight iPhone 5c models, eight iPhone 5s models, four iPhone 6 models, and four iPhone 6 Plus models — but this Q&A mostly covers collective differences for relative simplicity.

What are all the differences between the iPhone 6 and the iPhone 6 Plus models? Which should I buy?
With even a casual glance at an iPhone 6 and iPhone 6 Plus side-by-side, it is obvious that the iPhone 6 Plus is larger and has a correspondingly larger display.


Of course, these casual observations are correct, but there also are a number of other important differences that are not so obvious. It is worth noting that there are actually eight distinct iPhone 6 and iPhone 6 Plus models (four of each).


External Differences & Similarities


Both the iPhone 6 and iPhone 6 Plus use thin aluminum case designs with the front dominated by the display.


The displays are different, but they vary by more than the physical dimensions — 4.7″ (1334×750) for the iPhone 6 and 5.5″ (1920×1080) for the iPhone 6 Plus. Both screens are multitouch capable, have IPS technology, are LED-backlit and have a 500 cd/m2 typical maximum brightness as well as “dual-domain pixels” for a wider viewing angle.


However, the iPhone 6 has a superior 1400:1 contrast ratio compared to 1300:1 for the iPhone 6 Plus. The iPhone 6 Plus, on the other hand, has a higher pixel density, 401 ppi compared to 326 ppi for the iPhone 6. In practice, these differences are minor — and only those with extremely sharp vision will be able to differentiate the higher pixel density of the iPhone 6 Plus — but it is worth noting that the iPhone 6 Plus display is true “HD” (1920×1080), whereas the iPhone 6 display is not despite Apple’s identical “Retina HD” branding for the display in both models.

How fast are the iPhone 6 and iPhone 6 Plus compared to one another and the iPhone 5s and iPhone 5c models?
Apple’s official press release for the iPhone 6 and iPhone 6 Plus cheekily notes that these models represent the “biggest advancements in iPhone history,” in a nod to their large 4.7″ and 5.5″ displays.


The press release is a bit more modest about performance, though. It notes that these models provide “blazing fast performance” in the second paragraph and “faster performance” elsewhere, but provides no specifics as to exactly how much more “blazing” the performance is than earlier models. This quiet omission is a solid signal that the performance gains are fairly modest compared to other recent iPhone devices.
