So, have your sights set on the Samsung Galaxy S6 edge+? No wonder, this is one of the most exciting big-screen smartphones to hit the market recently! But it has to be considered that the phablet's outstanding design and impressive hardware power come at a price that may be too steep for some. Luckily, price-conscious buyers have a choice for a high-end smartphone that won't twist their pockets — we're speaking of the LG G4. By refusing to follow the prevailing design trends and utilizing carefully chosen hardware components, LG made a stand-out device whose imperfections are easily offset by its sub-$500 unlocked price, an affordable price tag by flagship smartphone standards. So, let's have a look at how LG's hero device compares with Samsung's latest and greatest!


Metal and glass sheen versus plastic and leather practicality.

The Galaxy S6 edge+, even if it's merely an oversized S6 edge, makes for quite the show with its futuristic dual-edge curved screen and impressive metal and glass build. The LG G4 is on a different side of the spectrum of attractive, because it's appearance is comparatively modest, yet unquestionably classy with its genuine leather back. Without it, the LG G4 looks like a well put together, all-plastic smartphone, which makes for a pleasing sight, but certainly doesn't exude the same premium feel. There's a practical advantage to the latter's utilitarian design, however. The Galaxy S6 edge+'s glass back is a fingerprint magnet that could easily crack upon an unfortunate impact with the pavement, while the LG G4 is pretty much immune against both problems.

Nearly everything found on the S6 edge is present in the S6 edge+, including the handy fingerprint sensor, the heart rate sensor, the rapid charging microUSB 2.0 port, and built-in wireless charging. The LG G4 is mostly devoid of these niceties, save for the rapid charging port and the optional wireless charging cover. What the LG G4 has, which the S6 edge+ doesn't, is the ability to swap its empty battery for a fresh one, or expand its built-in storage with a microSD card. Another interesting bullet point in the LG G4's design is the unusual positioning of its volume and power keys on the device's back panel. It's unusual, but it works, until you try setting the volume with the keys while the phone is laying on its back, and you go "eh...".

At 5.86 x 3.00 x 0.39 inches (148.9 x 76.1 x 9.8 mm), the LG G4 is smaller than the Galaxy S6 edge+, which measures 6.08 x 2.98 x 0.27 inches (154.4 x 75.8 x 6.9 mm). However, Samsung's phablet has a slightly bigger display diagonal (it's 5.7 inches vs 5.5 inches for the LG G4), and is also much thinner, contributing to an unquestionably modern feel. The weight difference between the two, at 5.40 oz (153 g) for the Galaxy S6 edge+ and 5.47 oz (155 g) for the LG G4, is negligible. And as for which one's more comfortable to hold, it's really a question of which one feels better in your hand. We believe LG's handset has the advantage of smoother curves that are more natural to the palm, whereas the S6 edge+'s metallic lines feel slightly sharp in comparison. But the truth is that neither device is really designed for one-handed use.

Both are excellent for multimedia, but Samsung's has a literal edge in color accuracy.

With its 5.7-inch, 1440 x 2560 resolution Super AMOLED display, the Samsung Galaxy S6 edge+ has a quite literal edge (or two) over the LG G4, which uses a 5.5-inch IPS LCD screen of the same exceedingly high resolution. Despite both screens being of Quad-HD resolution and high quality, there are stark differences between them in the way they reproduce those eye-popping visuals. Let's dig into the intricacies of our display measurement results.

Pixel density is great for both screens, coming in at 518 pixels per inch for the Galaxy S6 edge+ and 538ppi for the LG G4. Crispness aside, the S6 edge+ in 'Basic' screen mode has a color temperature of 6722 K, which is much closer to the reference 6500 K than the LG G4's 8031 K. 6500 K is the reference point where the mix of red and blue primary colors can be considered in balanced proportions. Temperatures above that result in perceived coldness of colors, while temperatures below are the opposite – warm. Thus, the LG G4 favors a colder color temperature, resulting in a dominant blue.

Next, let's have a look at the screens' minimum and maximum brightness levels. The former is useful to determine a display's readability in low-light conditions (darker displays put less strain on your eyes), while the latter makes or breaks a display's legibility in intense lighting. The Galaxy S6 edge+'s screen goes up to 502 nits of maximum brightness and down to just 1 nit, while the LG G4 goes up to 454 nits and down to 2 nits. These are both very good results, although the S6 edge+, obviously, is the brighter one.

Next, we'll discuss gamma value. The gamma curve is used to determine how accurately a display is able to reproduce images, in terms of shades, starting from the darkest and finishing with the brightest shades. Looking at the LG G4's measurements, its gamma value of 2.24 is actually pretty close to the 2.2 reference, which means color intensities are mostly evenly reproduced and there's no artificial contrast boosts or cuts to be aware of. With a slightly lesser value of 2.12, Samsung made the Galaxy S6 edge+'s lighter shades of gray a tad brighter than they would appear in reality, resulting in a deliberate contrast boost. Samsung likes to do that with recent Galaxy S displays, letting users enjoy colors a bit punchier than normal.

Where color balance is concerned, the S6 edge+ does present the primary colors in more correct proportions than its competitor, which is prone to exhibiting a blue-green color tint. This is due to an under-representation of red, caused by the colder color temperature. The brighter the image, the more red disappears to blue and green's advantage on the G4.

Finally, viewing angles! AMOLED screens, unfortunately, still aren't as solid as IPS LCD screens when it comes down to viewing angles and retaining color fidelity. The Galaxy S6 edge+ delivers outstanding viewing angles as far as retaining brightness and contrast goes, but on the downside, colors exhibit dramatic shifts in their quality as we turn the screen even slightly, which is not a problem on the LG G4. However, IPS LCD displays aren't immune to viewing angle defects, as they tend to distort their brightness and contrast output the more you shift the viewing angle.

All things considered, the Galaxy S6+ has a superior display in each aspect, partially save for viewing angles. The LG G4's screen is quite tolerable and certainly far from disappointing, but is definitely farther from ideal.

Galaxy S6 edge+ vs LG G4? S6 edge+ doesn't have any competition at all. It's a different league of it's own. Down right premium looks, top notch specs and matching performance. This comparison would only serve to highlight the shortfalls of G4. Eventhough G4 has the removable battery and microsd as advantages, it could in now way compete with S6/edge, same is the case with s6 edge+.

and the iPhone 6s and 6s Plus doesn't have any competition eiher, the phones are too good. Not even the S6 edge plus (which is crap) or the Note 5 (which is also crap) can not compete with the king and queen of smartphones.

are you serious....the iphones 6s and 6s plus,,,only 1080p....hmm....that is ancient resoltion....look at samung phones display and then apples...big difference ....ios need to be changed,,it looks cartoonist...also., ..apple...where can you customize the desktop....and 16 gb memory...come on...that is stiffing the customer...if apple would have upgraded the display, offered 32 gb memory, and made ios customizable,,,,maybe i would look

I would definately buy the S6 egde+ if it had IP68, micro SD and FM radio. But I don't believe PA's battery scores for Samsung phones (sorry). I had the S5 and I had to charge it once or twice a day, while it came close to my Z2 in PA's battery test which I still charge once every two days with heavy usage. So can someone confirm the 9 hours and 30 minutes?

Battery life is very tricky to test and lot of people may experience difference from the figures the tech mags report. The main issue here is unless everyone has the factory setup, there is no way the conditions can be similar. A few crap apps can screw batterylife of champs like Note 4.
But these tests would show a general trend and G4 is not doing well anywhere. But there are a lot of people in different forums who report real good battery life stats for Note 5.

I can tell you my s6 edge plus is a beast with the endurance of battery. I get well over a day of use with it. The s6 I had was terrible but this is different

The first problem with the comparison is that the devices cater to different people. Those power users who need things like expandable storage and a removable battery, vs those that prefer a tighter, all in experience.

The second problem is that just about anyone who wants the expandable storage and removable battery is far better suited picking up a Note 4 than the G4.

G4 is trillion times better value and being realistic, it's like 90% as good phone. That said, if you want the absolute best device money can buy at the moment (after Note 5) and want to show off with the Edge screen, S6 Edge+ is the phone to go.

No contest. The Edge+ wins on speed, display, and battery. The G4 only clearly wins on value. And removable battery and storage, if that's your thing.

Not really, it can be measured and the AMOLED display is better, brighter, more colour accurate when using the basic mode and you get deeper blacks.

AMOLED also has very good viewing angles, yes there is some colour shifting at extreme angles but it's still visible.

IPS sucks, I like my blacks to actually be black and not not light up the bloody room.

IPS is supposed to look more natural than AMOLED. So why are LG and Sony's LCDs way off in color balance (temperature) compared to Samsung's newest AMOLEDs? It's as if LG and Sony have been trying to compete with the "punchy but cold" look of the Galaxy S4/5 instead of the balanced and refined Note 4.

No accounting for taste, but it's hard to argue with the numbers and people's experience with the latest from Samsung.

I really wish these reviews would move the "premium build" BS to the last page of the review. Most people keep their phones in cases, but in any event it's subjective BS. The main part of the build that people interact with with their phones is the glass front and whatever buttons turn the thing on/off (as well as a fingerprint scanner if available).

And I feel that LG really nailed the "plastic but premium" feel with the G3 and G4. The problem with Samsung's older designs (S3, S4, S5, Note 3) is that they felt plasticky and cheap.

Battery life on my buddy's g4 isn't all that good. For me battery life and fluidity are the most important aspects to a phone

Makes sense, Galaxy S6 Edge + has better display, performance, battery life, build quality and a great camera but receives a lower score than the inferior LG G4.

Did they mention the LG G4 has horrible audio recording and video recorded is a much lower quality(lower bitrate) or that the LG G4's display is less colour accurate or that LG lower the rendering quality in 3D games by default.

Well okay.

Crazy how they are pretty much the same size overall. If they can make the GS7 like this, it could end up being smaller than all 4.7 inch display phones and 1st gen Moto X size. That would be amazing with a 5.1 inch display.

19. roldefol (Posts: 4365; Member since: 28 Jan 2011)

That would be geometrically improbable. A 5.2" display (which is where the GS7 is reportedly heading) must be 2.55" wide. The Moto X '13 was 2.57". So unless the GS7 goes with an edgeless display...

The Galaxy S6 has a pixel pitch of 1.2 and the LG G4 is 1.12, so any advantage gained from it's aperture advantage is lost and any differences are just software based. The GS6 also has way better mics and OIS/digital stabilization, where the LG G4 just stumbles.

The only thing that's kept me trying out the LG G4 is that ugly @$$ interface.
