LG G4 vs Apple iPhone 6



A 5.5-inch phone that retains the design language of the LG G3 with LG's signature rear-positioned buttons, the LG G4 focuses on two key areas for improvement: first, it’s style, with a new leather back cover option and second - an improved, 16-megapixel camera that aims to rival the best. One of these best devices that will be natural competition to the LG G4 is the Apple iPhone 6. A kind of a gold standard for design with its sleek metallic body, and reliable, consistently great 8-megapixel camera, the iPhone 6 might be smaller in size, but packs an equally sizable punch.

Apart from the size, the two differ mostly in that they run on two fairly different operating systems: the G4 runs on Android that is skinned to LG’s liking, while the iPhone runs on iOS 8 that takes pride in its user-friendly face.

In this full comparison between the LG G4 and Apple iPhone 6, we compare the two in all the important aspects, from the aforementioned design and camera, to their performance, call quality, and battery life. Let’s get right to it.


The LG G4 is a rather large phone, especially when compared with the sleek iPhone 6, but both have their distinct appeal. The leather back of the G4 feels soft and warm, while the iPhone 6 has a cold, but sturdy metal body...

The LG G4 comes in two versions differing only in their back cover: there is one with a diamond-shaped, 3D-like plastic finish that sells for the price of a regular flagship, and another model with a premium genuine leather back cover that is offered for $50 more. The first one is nice plastic, but still plastic. It is the leather one that is definitely the fancier one: it has got that signature stitch that goes right along the center, and different colors of it come with a different kind of leather. The black one, for instance, has a large porous structure, while the brown one has a finer grain to it, so we would recommend getting a hold of various color versions to pick your favorite not just by its color, but also by feel. The Apple iPhone 6, on the other hand, comes in a sturdy metal body that lacks the warmth and soft touch of leather. The aluminum is a cold material that just subconsciously says you’re holding a solid device that will last for a long time. It’s hard to pick a favorite between two vastly different materials - it will depend on your own preference.

In terms of size, the 5.5-inch LG G4 dwarfs the iPhone 6, which is also noticeably thinner and lighter: thickness is 0.27” (6.9mm) with the iPhone, and 0.25” to the whopping 0.39” (9.8mm) on the G4. In fact, the G4 is the thickest, chubbiest flagship of the year so far.

The interesting thing about the LG G4 is its Slim Arc curve up front: the screen is just slightly curved, but that slight curve reduces the chance of having your phone drop flat on its screen, and hence, the chances of breaking the display are probably smaller.

The color options on the LG G4 include: ceramic white, metallic gray and gold for the plastic model, and red, brown, blue, yellow, and black genuine leather. The iPhone 6, on the other hand, has a silver, gold, and dark grey color finishes.

It’s also worth pointing out that the iPhone 6 has a fingerprint scanner built right in the home key. Its primary purpose is to make your device more secure by locking it with your fingerprint, and you can use Apple Pay for cashless payments in the US. The LG G4, on its part, lacks a fingerprint scanner. The LG G4, on its part, has an IR blaster and an app that goes with it allowing you to control your TV or other electronics. This time, it’s the iPhone that lacks such a feature.

The LG G4 sports a super sharp 5.5-inch display with a Quad HD resolution, while the iPhone 6 sports a 4.7” screen with a resolution of 750 x 1334 pixels. Color accuracy is not perfect on both, but the iPhone 6 is much closer to the ideal.

The LG G4 features a 5.5-inch display with a resolution of 1440 x 2560 pixels, and it’s using an IPS LCD panel that LG claims has improved qualities over the G3 predecessor. The Apple iPhone 6, on its own, features a much smaller, 4.7-inch screen with a resolution of 750 × 1334 pixels and also uses IPS LCD technology. Both appear very sharp, but when you look up close you notice that the much larger pixel density of the LG G4 (538ppi) translates in sharper looking detail, much sharper than the iPhone 6 with its 326ppi. That’s something you notice mostly when looking at the phone from very up close, but not so much in daily use.

Since both phones would appear sharp enough for most people, it is arguably the color accuracy that makes the bigger difference for the end user. The LG G4 features a so-called 'Quantum Display', but how does this marketing term translate into real-life? First, we look at gamma, a value indicating whether the luminance of the screen is appropriate at various nuance levels. Ideally, it should ideally be around 2.2, and good news is that the G4 is just about at that sweet spot with a gamma measuring 2.24. The iPhone 6 also excels in this regard with a gamma of 2.23, so we can conclude that on both phones, darker areas will appear as dark as they should be, while brighter areas of images will be as bright as they should be.

Next, we look at color balance, and unfortunately that’s where we can see that the LG G4 has a preference for colder tonalities. The white point reference value we are looking for here is 6500K, and the G4 is notably above it, in the territories where whites appear bluish at 8000K. The iPhone 6, on the other hand, is also a bit on the cold side, but just slightly with a white point of about 7150K.

Finally, we test the actual color accuracy. We look for compliance with the sRGB color gamut, the color space that pretty much all content on the web is optimized for. The LG G4 has colors that are wider than sRGB, meaning they appear unrealistically overblown. Some people might like it, but the screen is not color accurate by a long shot. The iPhone 6, on the other hand, is not perfectly calibrated either, but is much closer to that sought after perfection as its colors nearly match the reference values.

All tech explanations aside, we can sum it all up by saying that the LG G4 has overblown, eye-popping colors that might please some people, but are not color accurate. The iPhone 6 is closer to that ideal, but also not there.
