The Samsung Galaxy S6 edge might have sounded like a sci-fi gadget a few years ago with its flexible screen that curves towards both sides, but fast forward to today and this futuristic gadget has become a reality: in 2015, the S6 edge will be battling for attention on store shelves with more traditionally shaped devices. Its biggest rival? The Apple iPhone 6.

While there are two edges that make the phone look cool, you get to pick to use only one - either the left or the right one - for quick access to contacts and notifications. For all else, the Galaxy S6 edge is identical to its S6 sibling.

How does it compare to the iPhone 6, though? Both are stylish devices - the iPhone is made from metal, while the S6 edge features glass on the front and back, and metal for the frame. In order to decide which one to buy, we look at their performance, camera capabilities, battery life and more. And yes, we do explore how TouchWiz has changed and whether the change is for the better.

Read on as we explore the Galaxy S6 edge, iPhone 6 and all their secrets to try and give you an answer to the big question: which one should you buy.


Samsung has stepped up to have a truly stylish and futuristic device with the S6 edge, almost on par with the all-aluminum iPhone 6. Both are impressively thin phones.

After years of uninspiring plastic designs, Samsung has finally listened in: the new Galaxy S6 edge is made of fine-quality materials and has a truly premium feel. The S6 edge features a sturdy metal frame sandwiched between two pieces of glass on the front and back. Samsung has also added new color options: the S6 edge is available in a choice of black, white, gold, and green. The Apple iPhone 6, on the other hand, features an all-aluminum build with a choice of space grey, silver, and gold.

Both the Galaxy S6 edge and iPhone 6 are impressively thin devices: the iPhone 6 is a hair thinner at 6.9mm, while the Galaxy S6 edge measures 7mm in thickness. The difference is barely noticeable, but what is noticeable is that both phones have a protruding camera module resulting in a hump on the back of both devices (a significantly larger one on the Galaxy S6 edge).

The two phones are fairly lightweight: 4.66oz for the S6 edge and 4.55oz for the iPhone 6. Given the larger screen in the Galaxy S6 edge, it’s also no surprise that the Samsung phone is also larger: 5.59” tall and 2.76” wide, while the iPhone 6 is a more manageable 5.44” tall and 2.64” wide. However, saying that the S6 edge is larger would not give Samsung credit where credit is due, and that is that the S6 edge is one of the most compact and single-hand-friendly phones for its 5.1” screen size.

Buttons are clicky, large enough and have a reassuring tactile feedback on both phones, and the positioning of the keys is identical: the lock key is on the right and the volume buttons - on the left.

We’re also happy to see a fingerprint sensor built in the home button on both phones: the Galaxy S6 edge is the first phone from Samsung to use a new tap (rather than swipe) based fingerprint reader, and it works quickly and accurately, just as the one on the iPhone 6. While you are limited to using the fingerprint scanner on the iPhone for Apple Pay, unlocking the phone and authorizing App Store purchases, though, the fingerprint functionality on the Galaxy S6 edge is not limited to that and you can use it to protect particular apps and functionalities (via third party apps).

The edges are a nice cool feature, but it’s more about the cool factor rather than any huge actual benefits. For all else, the Galaxy S6 edge has a remarkably well calibrated 5.1” Super AMOLED Quad HD display, taking it a step ahead of the already great iPhone 6 LCD screen.

The Samsung Galaxy S6 edge features a 5.1-inch Super AMOLED display, larger than the 4.7” IPS LCD screen of the iPhone 6. With a resolution of 1440 x 2560 pixels (Quad HD), the screen on the Galaxy S6 edge is extremely crisp and paper-like with a pixel density of the record 577ppi. The iPhone 6, on the other hand, features a more modest resolution of 750 x 1334 pixels, which works out to a pixel density of 326ppi. The difference in the numbers is staggering, but the actually perceptible difference in sharpness is not that big at all: you’d notice a slight pixelization on the iPhone if you stare from very up close, while from regular distances the difference is minimal.

The big story for the S6 edge is clearly the curved rims on both sides of the display. The added functionality boils down to three main features: People Edge (where you get quick access to your favorite contacts), Edge Lighting (where the edge lights up when you get incoming calls, messages, or other notifications), and Information Stream (which brings you news/events ticker functionality). Also, the edges just plain look cool.

For all else, we will look at the S6 edge as a regular display. With sharpness now reaching a level where it’s hard to notice pixelization on all major flagships, the last remaining frontier to conquer in the way towards the ideal display seems to be image quality. Good news is that the Galaxy S6 edge and the iPhone 6 feature two of the best smartphone displays out there.

In the S6 edge you get to those nice colors in ‘Basic’ screen mode (go into Settings > Display > Screen mode, and select Basic), while other modes serve unnatural, overblown colors. Colors in Basic mode stick to the industry-standard sRGB color space with impressive accuracy: color temperature at 6800K means that you get natural-looking whites (with just a slight bit of a cold tint), and gamma at 2.2 is right where it should be, meaning that image brightness is accurate. Impressively, color saturations are practically perfectly seated in their reference values, resulting in great color calibration. The iPhone 6, on its part, also has a very good LCD display when it comes to colors, but it’s a step below the nearly perfect calibration of the Galaxy S6: whites are a bit colder, while color errors are minimal, but still higher than on the S6.

Samsung has made some notable progress with maximizing brightness on AMOLED displays. The Galaxy S6 edge, in particular, comes with Samsung’s most luminant AMOLED reaching 553 nits at maximum levels. Brightness on the S6 edge is still a step below what the iPhone 6’s LCD display, though, as that can put out with 606 nits of peak luminance.

"But in low-light conditions it is a step behind the iPhone 6." Kidding me??? I've seen lots of low light comparisons and S6 has blown iPhone 6 out of the water. I think even you haven't seen your own samples yet!!!

That's called blind comparison. "Blind" here means closing the eyes and just choosing Apple automatically.

There are a lot of Apple fanboys here (they call themselves "techies" often and apparently) that the site has to cater to as well. They also have to bow to Apple products if they want access to Apple events and such just like all other major publications (no one wants to be the next Computer Bild). You can never EVER give a definitive win to anything other than an Apple product. If comparing to an Apple product, you have to find every little point you can give to Apple or even make some up so at the end of the article you can say it is all about preference because they are basically equal devices.

Yesterday inwas attacked by a flock of iSheeps just because I pointed out the biasness in Nick's reviews of Samsung products, always degrading and bashing them. I am glad that it's not just me on this site that see how PA are always afraid of losing that precious invitation letter that Apple send to their loyal tech sites on the 10th of September.

true that , even in this lowlight comparison, SS is clearly the winner , there is a lot of noise on the IP6's photo. this guy is clearly bias

Well at least they havent pointed the S6 edge directly into the lightsource as they did with the ordinary S6. BUt it also clearly shows that it was those lights that messed up the S6, as these from the S6 edge are clearly better than the iphone 6.

that conclusion is quite the biggest bulls**t I've ever read.. How is the ios8 experience in any way perfected? Have you ever used ios 8? it's still i freaking mess and far away from coming close to perfect. And please tell me any phoneapp that is on ios and not on android anybody is using. In fact, if you put the sentence of you have it is even wrong from the beginning on since playstore has more apps. Please somebody finally grow some balls and call it out that the s6 (especially edge) is crushing absolutely every competition right now. You don't have to be afraid of applefanboys leaving this site then. Most of the hardcore fans aren't here anyway, and the other fews are a diminishing numbers. The rest can take it if a phone is simply better in every term

PA's comparisons are so obviously half assed and amateurish that I wonder why are they even doing them. Go to GSMArena and see how it's done!

"Samsung has stepped up to have a truly stylish and futuristic device with the S6 edge, almost on par with the all-aluminum iPhone 6. Both are impressively thin phones." I love apple I must admit, I have even fallen in love with their IOS but come on. You must be very biased or absolutely blind to say the s6 edge is almost on par with the iPhone? Who sees an iPhone and goes like wow??? Have you any idea the number of people saying wow after they see the s6 edge in the mall? My 6 plus felt like a dianasor next to s6 edge. When will you guys ever be realistic in life? Is Apple paying you guys or what? I don't even know why the world makes it look like Apple is some God. I love their products but let it end there. When competition surpass the iPhone grow some balls and say it. If the s6 edge isn't above the iPhone I wouldn't be selling my 6 plus now.

As a former Droid user and current iPhone user I have to reluctantly agree that the reviewer seemed to give favor to the iPhone in some catagories. I'm in the market for a new cell and do not know yet what my next platform will be. One area which eliminates bias is benchmarking. I fully expected the more powerful cpu of the S6 to trunce the iP6; but it did not. With most of the tests going to the iP6. BOTH platforms have their fanboys. But it's interesting that none of the protesters here are mentioning the S6's benchmark loss. Instead their beating up on the reviewer. Now I'm not saying the iP6 was the winner; in fact I think it lost. Especially in the battery tests which is traditionally an Apple boasting point. While the S6 is reviled for it's TouchWiz, which is better this time around. I just surfed to this site from PhoneScoop. They also were not overly impressed with the S6. So it isn't just this site that doesn't favor the S6 guys, so don't be too rough on P.A. Both cells have their pros/cons. I won't have an easy buying decision this time around, thats for sure! Peace.

The TI 92 calculator also benchmarks well. I don't think it is a better device than the Iphone 6 or S6 Edge.

the problem with benchmarks is that most people even geeks no little about performance and system architecture and whats important , they look at shallow numbers and think bigger is better. they love bigger numbers more cores and think higher ghz is king. same with megapixels and PPI. Most people don't read sites like Anandtech , which has been prasing Apple's cyclone architecture for 2 years , since it does away with big.little and creates a even more efficient system , just 2 cores that are very powerful and efficient which still lead in single core perfromance and FPS. when it comes to processors think Intel vs AMD , intel always has less cores and lower clock speeds but wins in raw performance , esepcially in gaming where single core performance is king. then when you add in Metal API/swift and Apple's lead in real world performance is even more...

This isn't a dig at any phone, its a dig at PA lack of testicle fortitude and being to gutless to upset either Apple or Samsung. When the compare the 2 phones they always conclude there is no winner, but when they review each phone individually they give them actual scores. Phone Arenas own system gives the following results: Galaxy S6 & S6 Edge = 9.3 IPhone 6 & & Plus = 9.0 Why do they fail to mention any score when the test them against each other?? I think I just come to PA as I like to end my day by reading more and knowing less.

First off the iPhone iOS8 sucks, it's laggy and slow. I would never say that iOS8 is better than Samsung software. Awful conclusion
