iPhone 6 or LG G4? We compare specs to see how LG's new flagship measures up to Apple's smartphone

Another Android flagship has landed, hoping to take a bite out of Apple's smartphone profits. LG has released its successor to the the LG G3, the TrustedReviews Phone of the Year 2014, and it's one of the best Android phones on the market.

The question is, how does it fare against Apple's uber-popular flagship phone, the iPhone 6?

We've lived with both now and here's how the two compare.

LG G4 vs iPhone 6: Design

LG G4: 9.8mm thick, 155g, curved design, plastic edge, removable back with choice of materials, rear button

iPhone 6: 6.9mm thick, 129g, anodised aluminium back, Space Grey/Silver/Gold

Apple’s current flagship signalled a radical change in design. It’s significantly bigger than the iPhone 5S for starters. It now has an aluminium unibody with a curved trim, those now familiar antenna lines, and a much more useful Touch ID fingerprint sensor baked into the home button.

It’s still a great looker and beautifully built, but it’s by no means a visually iconic smartphone like previous iPhones have been. Its competitors have certainly caught up on this front, especially Samsung. But how about LG?

The LG G3 was all plastic and not all that fantastic to look at. It’s by no means ugly, but it didn’t exactly offer anything ground-breaking in terms of design. For the G4, LG is still sticking with plastic and the distinctive rear button approach, but it’s going slightly bigger and taking some design inspiration from the G Flex 2 with a slightly curved body.

But the big news is the new leather back that LG has offered as an option (among other materials). It’s certainly going to turn more heads than the G3, though we suspect the verdict will be far from unanimous.

There’s also the fact that this is a mere facade, as evidenced by the decidedly plastic model we had in for review. This remains a thin, bendy, removable plastic cover - albeit a tarted up one.

The iPhone 6 isn’t the best-looking iPhone ever, but it’s much better to look at and hold than the LG G4

LG G4 vs iPhone 6: Screen

LG G4: 5.5-inch, 2560 x 1440 IPS Quantum display, 538 ppi, 454 nits brightness

iPhone 6: 4.7-inch, 1334 x 750 IPS LCD, 326 ppi, 504 nits brightness

Before we compare resolutions, there’s the obvious difference in screen size. The G4 has a bigger one than the iPhone 6.

Despite the LG G4’s 5.5-inch ‘phablet’ dimensions, it’s actually not too much of a problem wielding it in one hand. Like its predecessor, that’s thanks largely to some extremely thin bezels.

Of course, the iPhone 6 represents a sizeable increase in size over previous models, but it successfully deals with the jump. It doesn’t sound like a big difference when you move from the 4-inch screen on the iPhone 5S to the iPhone 6’s 4.7-inch display, but it really is - and you won’t turn back when you go with a bigger screen.

The G4 features a QHD ‘2k’ display following its introduction on the G3. Unlike the S6 and S6 Edge’s QHD AMOLED screens, LG is using an IPS LCD panel that it calls a Quantum Display. It’s pretty much the same deal as the G3, although LG has made some improvements to increase colour gamut, delivering a contrast ratio higher than most QHD LCD panels and a 30 percent brightness increase to boot.

G4 Zip 23

It’s definitely a step forward from the LG G3’s display, despite the similar specs on paper. However, we did notice that colours can look a little too vibrant here, with no options to tone it down at all.

So how does that compare to the iPhone 6? From a specs sheet point of view, the G4’s screen is going to be sharper, more colourful and altogether more vibrant. But you have to factor in that Apple’s flagship’s 1334 x 750 resolution is still well suited to a 4.7-inch IPS LCD screen. At this size, even 1080p is a bit of a luxury.

What’s more, the iPhone 6 display is brilliantly calibrated so that contrast and colour accuracy are spot on. It’s one of the best displays in the business.

LG G4 vs iPhone 6: Performance

LG G4: Hexa-core Qualcomm Snapdragon 808 chipset 1.8GHz dual-core – 1.44GHz quad-core, Adreno 418 GPU, 3GB RAM

iPhone 6: Apple A8 64-bit dual-core 1.4GHz, PowerVR GX6450 GPU, 1GB RAM

This is arguably the biggest headline-grabbing story. After delivering the first Snapdragon 810-powered phone earlier this year with the G Flex 2, LG has decided to opt for an hexa-core Snapdragon 808 - a step back that could further highlight issues with Qualcomm’s top line chipset.

Qualcomm insists that this was an informed and pre-meditated decision based on the fact that the Snapdragon 808 is better suited to 2K displays, but there remains questions over the reliability of the Snapdragon 810.

The 808 is still a 64-bit processor like the 810, but it uses four Cortex A53 and two low-power Cortex A57 cores. That’s accompanied by 3GB of RAM and an Adreno 418 GPU for gaming.

It means that we’re left with a chip that, while fast, isn’t quite top of the line. Besides the Snapdragon 810, it also falls short of the Galaxy S6’s custom Exynos CPU.

More importantly, however, the Snapdragon 808 was faster than the iPhone 6 A8 chip in our benchmarks - though only slightly.

Apple relies on a dual-core setup with a PowerVR GX6450 GPU and 1GB RAM. There are fewer cores and RAM compared to the G4, but those aren’t the issues they might seem to be.

In terms of RAM, iOS is known to be less demanding than Android. Meanwhile, modern smartphones don’t really benefit from four cores as much as they do from one or two fast ones.

It loses out on the numbers game, but as we’ve found living with the iPhone 6, it’s more than suitable for keeping things slick and speedy.

LG G4 vs iPhone 6: Storage

LG G4: 32GB on-board, microSD up to 128GB

iPhone 6: 16GB, 64GB, 128GB, no micro SD card support

These two phones take completely different approaches to storage.

While the LG G4 comes with only one option of 32GB of internal storage, the iPhone 6 comes with a choice of 16GB, 64GB, or 128GB.

What’s more, while the LG G4 has a microSD slot that allows you to expand by up to 128GB, the iPhone 6 (as ever) has none.

In truth, we prefer a large amount of internal storage to optional microSD. It’s faster and less fiddly. However, we feel that Apple made a mistake in making 16GB the entry-level amount and ditching 32GB.

16GB isn’t quite enough for a flagship phone.

LG G4 vs iPhone 6: Software

LG G4: Android 5.1 Lollipop with Optimus UX

iPhone 6: iOS 8.3

It’s the age old battle (well, it’s a seven-year-old battle at least). Android versus iOS. Which one’s better?

It’s tough to call, but most Android manufacturers make it a easier by layering on clunky custom UIs. While the LG G4’s isn’t exactly bad, it’s still not as good as stock Android 5.1, and nor is it as good as iOS 8.3 on the iPhone 6.

There’s just something slightly cheap and amateurish about LG’s Optimus UX, and there’s still a hint of lag to it even with the G4’s new and improved CPU.

iOS 8.3 on the iPhone 6, by contrast, remains a slick delight of an operating system. No, it’s not as good for those who like to tweak and personalise their home screens to the Nth degree. But it’s fluid and consistent and easy to use, which is what really matters to us.

Until LG offers the ability to go full stock Android with its handsets, we fear this particular section is always going to go in favour of Apple. It’s in good company with Samsung and HTC, among others.

LG G4 vs iPhone 6: Camera

LG G4: 16-megapixel, 1/2.6 sensor, f/1.8 lens, optical image stabilisation, Colour spectrum sensor

iPhone 6: 8 megapixel, phase detection, dual LED ‘True Tone’ flash

We wouldn’t have predicted this when the iPhone 6 hit shots towards the end of 2014, but the LG has managed to pip the Apple flagship’s imperious camera with the G4.

It really is an impressive piece of work. Yes, it’s got double the megapixel count, but that’s by the by. The LG G4 wins this based on other factors, such as a wide-open f/1.8 aperture, a large 1/2.6-inch image sensor, optical image stabilisation, and a colour spectrum sensor for better colour accuracy.

All of this contributes to images that simply look better than their iPhone 6 counterparts - particularly in low-light shots, which is the bane of smartphone photography.

LG has also provided the most intuitive set of manual controls on any smartphone camera we’ve used, which is an area Apple has always shied away from. Oh, and it also has RAW support for pure, unprocessed images.

Alongside the Samsung Galaxy S6, these are two of the best cameraphones on the market. We reckon that the LG G4 could be the best of the lot.

LG G4 vs iPhone 6: Battery Life

LG G4: 3000mAh removable battery, Quick charging

iPhone 6: 1810mAh non-removable battery

Those figures above don’t really mean a lot. These phones are just built too differently to make a physical battery capacity comparison meaningful.

The LG G4 has a much bigger, much brighter display to run, a different kind of multi-core processor, and a completely different operating system to the iPhone 6.

In our standard looped video test, the LG G4 managed just under 11 hours for our standard looped video test, while the iPhone 6 managed 10 - a clear (if not massive) win for the LG.

When it comes down to real world usage, the two are comparable. You can get home from work with the LG G4 with around 40 percent power left in the tank, while back when we tested the iPhone 6 this varied between 30 and 60 percent depending on usage.

Neither has the best battery life we’ve ever seen, then, but they’re not bad - and more importantly pretty even.

We should also note that the LG G4’s battery is removable, which will excite a few - but mean nothing to most. How many people do you know who carry a spare battery around with them?

Both phones charge in around two hours, which is plenty fast enough.

The Verdict

We were massive fans of last year’s LG G3. As we’ve mentioned, we named it our phone of the year.

While the LG G4 is an undoubted improvement in numerous respects, however, we feel that LG hasn’t quite carried things far enough. In particular, it’s missed the mark in terms of design.

We’ve criticised the HTC One M9 and praised the Samsung Galaxy based primarily on the freshness of their designs, or lack thereof, so it only seems fair that we hold LG to the same standards. No amount of leather can make up for cheap plastic build quality.

Though the iPhone 6 isn’t our favourite ever iPhone design, meanwhile, it is both new and elegant. What’s more, Apple has managed to make the move to a larger display a lot less traumatic for iOS users than it could have been.

Besides hardware, LG’s heavy-handed software tweaks also continue to grate a little, and it doesn’t sit well at all alongside the clean and crisp iOS 8.3.

The one area where LG has trumped Apple - and somewhat surprisingly at that - is in the camera stakes. The iPhone 6 initially seemed untouchable in this field, but first the Galaxy S6 and now the LG G4 have come and knocked it off its photographic perch.

Overall, it’s a win for the iPhone 6 thanks to its all-round competence rather than any outstanding features. LG hasn’t made any glaring mistakes here, but it has just fallen a little short in a few vital areas

You need to compare the G4 against the 6 plus as they have the same screen size.

The 6 plus is thinner by a mm or so but is ginormous to hold in comparison to the G4.

There seems to be a lot of iPhone bias in these reviews. Now I appreciate that this is not a hands on review. However, please list the areas in which the iPhone 6 surpasses the G4 or to that matter the S6. I do not mean iOS because that is down to OS choice that the consumer will make based on personal choice, current phone or other products owned. I do not mean a fingerprint scanner or payment system because that is not an essential element of a smartphone in my opinion. Please begin. Oh, and just one comment on the iPhone camera. Ease of use and uncomplicated software enables the iPhone to shoot nice pictures in favourable conditions. It's "one of the best all round smartphone cameras" for people who don't want a great deal of manual control over their images. Special effects and creative filters have their place. But I think any serious photographer would take raw detail in post processing every time.

Sounds like your feelings got hurt. Would you be calling it an LG biased review had the author given most points to the LG G4? Exactly. So deal with YOUR biases first before you accuse someone else of the same.
Apparently you read very little of the article before you broke your neck to get to the comment section, because the author presented the very items you requested in your post.
Notice how you mentioned personal "choice" when you downplayed the OS or fingerprint scanner and payment system as non essentials to you in regards to comparisons. Well guess what? The author of the article reserves the right as well to decide what is essential to him.
Class dismissed.

Please check your facts the LG G4 can support up to a 2Tb Sd Card not a 128Gb. I own both the G4 and Iphone and love them both, but storage wise the G4 blows every phone out the water.

Since various people use their phones for various things, it is normal in an overall competition for the phone that is overall better to win. Like it or not the iPhones 6 delivers for most people, may not be better in some areas that are crucial to you, which means for you the LG G4 is better.

I for one am tired of IOS, been using it since the iPhone 4, tried to switch to Android twice, and while I have been very happy about things that work better than IOS on Adroid, I have been frustrated by those who don't. Little things, I admit, but little things pile up.

What Apple does well is make as many people as possible happy, that's why they keep winning comparisons, life with an iPhone may not work as you dream it to (like some Android features do), but it also doesn't fail anywhere.

Gotta be kidding me. iOS is horrible and very amateurish. And Apple products are nothing more than overpriced status symbols these days that do not offer more productivity than non-iOS/Mac counterparts.

The problem is, it seems that EVERY reviewer is biased toward iOS.
Every time any Android phone is compared to an iPhone, the iPhone almost ALWAYS wins. There's really hardly such thing as "LG bias" out there.


September 17, 2015, 10:25 pm

Definitely biased towards the iPhone like most reviewers...this site should be called "Biased Reviews".


September 25, 2015, 10:44 am

I like how when they're comparing the two it's quite obvious who the winner is, LG.. Better and bigger screen, way better camera, more storage for cheaper, longer battery life, and fast charging.. yet iphone is their favorite??

Sorry, but this review is a joke. The G4 crushes the iphone in almost every category. No amount of pay-to-play $$$ from Apple to reviewers can change that. Honestly, I had my doubts about the step down in CPU from the G3 that LG decided on, then I got my hands on a G4 and those doubts were gone. This phone SCREAMS power. It responds instantly to anything I ask it to do, apps and games load faster than on any phone or tablet I've ever owned, and I've yet to run into any lag problems. I don't know where you get your claim that the battery needs two hours to charge, I usually end the day somewhere between 10%-20% battery charge, it will be back to 100% less than an hour after I plug it in. "Stock" Android? Who cares. I love the LG interface, it's well laid out and highly customizable. Just because Google and Apple have no imagination when it comes to interface layouts does not mean everyone else is doing it wrong. Or maybe your problem is you are too used to that unholy mess of icons that every iOS device ends up with on the screen. As for the body build, and shape, that's another "who cares?" The curved back of the G4 rests perfectly in my hand, and the plastic two-piece body is a non-issue - my G4 was in a wrap-around hard case 2 seconds after it left the box.

Once again, an Android manufacturer has come out with a phone that blows the iPhone not only "out of the water", but right off the planet, but as usual, all the bought and paid for "Apple Cheerleaders" can say is "The iPhone is still better."

Keep telling yourselves that guys...

As far as storage goes, it did. Then the Droid Turbo 2 was released, and decimated the G4 on that front...
