Samsung Galaxy S6 edge vs Sony Xperia Z3

Introduction

We’ve said it before, and we’ll say it again. The Sony Xperia Z3 has arguably the most underrated designs around! Being good looking is one thing, but the designers over at Sony’s camp delivered an impressive offering in the Xperia Z3 – one that adds a higher degree of water-resistance protection, which isn’t something we tend to see too much of nowadays in flagships.

On the flip side, the Samsung Galaxy S6 edge bears one eye-catching aesthetics with is unique dual-curved screen. Add to that, Sammy’s transformation is realized with the unveiling of its latest flagship smartphones, mainly because the designs now feature that premium quality that was non-existent with its previous efforts. Between them, we know the advantages that come along with being the newer product, especially from a specifications point, but the Xperia Z3 can’t be neglected either.

Design

The S6 takes charge with its dramatically different design, one that’s now premium in nature, but the Xperia Z3 is one of the last remaining flagships to offer a water resistant construction.

With every new Galaxy S release, Samsung has historically built upon the base by refining what's already there and adding some extra on top. With the Galaxy S6, however, the electronics giant has focused far more on the latter than on the former. To that end, instead of the plasticky shell of the Galaxy S5, Samsung has adopted a metal frame that hugs the device all over and nestles within two sheets of Corning Gorilla Glass 4 – one placed in front of the display, and the other to protect the rear.

Samsung didn't stop there, instead opting to carve several 'nano layers' into the shell. The result is a front and back that reflect light in different hues depending on your viewing angle. Also, we can’t forget about some of the handset’s key features – like its improved fingerprint sensor, built-in wireless charging, heart rate sensor, and IR blaster. In achieving a higher degree of craftsmanship and premium design, the Galaxy S6 edge, however, is stripped of some key design features that were once notable qualities with its predecessor.

What really sets the S6 edge apart from everything else is its unique dual-curved display, where both edges feature a subtle curve. We’ll admit that it supplements its aesthetic appeal, but it comes with some precautions as well – as in the way we hold it, just because it feels rather sharp in the hand. In doing this, it certainly does not make it the most comfortable thing, though, some folks will gladly still take it primarily for the aesthetics. However, we have to point out that this design isn’t water-resistant.

And with that, we have to look at the Sony Xperia Z3 longingly and admire the fact that it’s one of the few, remaining flagships to qualify being regarded as water-resistant with its design. That’s a testament to say the least, since it doesn’t make that many sacrifices whatsoever with its aesthetics and construction – it’s relatively slim and premium. Surprisingly enough, it shares some of the same design characteristics as its rival, such as its premium glass surfaces and metal unibody.

At the same time, too, it’s able to accommodate a handy, and always useful microSD card slot and dedicated shutter key. Not surprisingly, the Galaxy S6 edge earns adulation and commendation for its stark redesign, one that’s undoubtedly now deemed as premium, but we can’t neglect to forget about the Xperia Z3’s design either.

Display

Not only is the S6 edge’s display cool looking, it’s also one of the brightest and most color accurate.

Being almost a year newer has its advantages, especially knowing Samsung’s insatiable appetite for pushing the boundaries. Clearly within the flagship range, the Xperia Z3’s 5.2-inch 1080 x 1920 LCD display has several good qualities about it, but it looks daunting on paper in comparison to the Galaxy S6 edge’s dazzling 5.1-inch 1440 x 2560 Super AMOLED dual-curved display.

In all fairness, it’s quite difficult in deciphering the detail superiority of the Galaxy S6’s display over the Xperia Z3 when looking at the two from a normal distance – they’re both sharp and pleasing to the eye. Moving ever so closer, however, that’s when we begin to visualize the astounding level of detail produced by the quad-HD resolution of the Galaxy S6 edge’s screen. For practical usage, though, there’s no denying that they’re both on equal ground.Now, let's talk about color calibration. With the Samsung Galaxy S6 edge set in the non-default Basic display mode, we're looking at a spot-on color temperature of 6800K (6500K being the desired optimal value), while the Xperia Z3 offers the very unsatisfactory 10324K. In real terms, this means that the Xperia Z3’s display is cold (or bluish) and that's especially visible with whites and various shades of gray. In comparison, Samsung's device offers realistic whites that are... well, white!

Were we to draw the line right here, the Xperia Z3 would only suffer a relatively small defeat, instead of being steamrolled as it is in reality. Indeed, the Galaxy S6 edge's display also proves far better in terms of color accuracy, with essentially every shade hitting its desired target at every intensity level, while the Z3 falters significantly in comparison – the hue presentation is all over the place when referenced to the standard, as you can see in the color charts below. In reality, the S6 edge’s panel replicates colors with accuracy, while the Z3’s screen tries to be more saturated and punchy, which, however, backfires significantly, resulting in a severely inaccurate screen.

Details and colors aside, the Z3’s LCD-based display shines strongly at 713 nits, making it especially easy to view outdoors with the sun present. Once known to be the among the worst display technologies when it came to maximum brightness, Super AMOLED has taken a great leap forward in recent memory, as the S6 edge’s Super AMOLED display musters up a respectable 553 nits.

And lastly, we can’t forget to mention the added functionality brought on by the dual-curved display of the S6 edge. From being able to access some of our favorite contacts from the lock and home screen, to the cool visualizing pattern when we receive incoming calls from our favorite contacts, and the notification tickers that bring info to one of its edges, the dual-curved display adds to the phone’s arsenal, but as we’ve detailed already, it’s most profound for the aesthetics.

Interface and Functionality

TouchWiz receives a new, more toned down redesign, but it’s still a power house experience in comparison to Sony’s Xperia UI.

While Samsung's Galaxy S devices have always shipped with nothing less than the best available at the time in terms of hardware, we've often found ourselves wishing it did more on the software side. Its proprietary TouchWiz layout has often proved sluggish and less responsive than what some competitors had to offer – a sight that the Samsung faithful only tolerated because of the smorgasbord of extra features the platform gave them access to. With the Galaxy S6 edge, however, the company has finally come to sense, and has carried out a number of software optimizations that make the Galaxy S6's software both easier to understand and faster than ever before.


Although it hasn’t made the jump to Lollipop, which is rather unnerving because it’s been around for some time now, Sony's Xperia UI running on top of Android 4.4.4 KitKat is a bit closer to the stock look than Samsung's TouchWiz, as it has way less extra functions. It adds some light multitasking tools like the Small Apps suite, which lets you hover up to five windowed apps, resize and move them around. What separates it from the Galaxy S6 edge is its tight PlayStation integration – where it can be set up for remote play, as in being able to stream most of your PlayStation 4 games directly to the Xperia Z3.


Visuals have never been a strong point for TouchWiz, but with this new version, however, Samsung has added support for third-party themes. Sure, it’s an appreciable thing to have, mainly because the themes help to mask TouchWiz’s otherwise bland visual presentation. On the software feature side, TouchWiz still adheres to the needs of power users because of its exhausted set of software features – they include the fingerprint scanner (still embedded in the physical Home button) that is now of the touch, not swipe, type, finally allowing for a hassle-free unlock. In addition, TouchWiz also offers software features like MultiWindow (run two apps simultaneously), and Private and Car modes (hide sensitive content / dashboard with bigger icons and essential apps only).

Processor and Memory

Both are impressively responsive, but the Galaxy S6 edge’s new piece of silicon exhibits more fluidness with its execution.

For the longest time, Samsung and Qualcomm worked together on the former's flagship lines, though the chip maker didn't always get all the orders – the rest went to Samsung's then fledgling semiconductor division making the Exynos chipsets. With the Galaxy S6 edge, however, Samsung was ready for a monumental shift, and Qualcomm is no longer part of the game. Instead, the S6 edge relies on a home-grown Exynos 7420.

The 7420 is an octa-core processor, built on a 14nm node, with two clusters made up by four cores arranged in a big.LITTLE configuration and Mali-T760 graphics. We have one group of power-efficient ARM Cortex-A53 CPUs, and another with powerful Cortex-A57 ones. The idea behind the arrangement is simple to understand – the efficient team of cores takes care of most trivial tasks, while the speedy A57 cores kick in when power is required. If maximum performance is what you need, the Exynos 7420 can switch all eight cores on and work them simultaneously.

The newness of the Galaxy S6 edge allows it to benefit over the Xperia Z3, which is powered by a last-generation quad-core 2.5GHz Qualcomm Snapdragon 801 MSM8974-AC processor. In dissecting its performance, it seems to be great, both around the interface, and within apps, including 3D games. There isn't any occasional choppiness that would hinder the experience, but as we meticulously compare their responses, it’s just a smidgen behind the Galaxy S6 edge’s exquisite fluidness. Don’t get wrong, most people would be satisfied by its responsiveness, but a higher level is achieved by Sammy’s pride and joy – plus, the benchmarks show the awesome muscle power of the Galaxy S6 edge.

As for memory, we have 3 gigs of LPDDR4 RAM with the Galaxy S6 edge, and a minimum of 32GB of internal storage. The Xperia Z3, on the other hand, is outfitted with half that capacity at only 16GB. That’s still plentiful enough for most people, but it can be supplemented thanks in part to its microSD card slot – something that has unexpectedly made a departure with the S6 edge this year. For some folks, the convenience of the microSD card slot is invaluable.

Internet and Connectivity

Smooth browsing is what we've been getting with each and every flagship for the past few years, and Samsung's and Sony's offerings don't fail to deliver just that. Courtesy of their powerful internals, both devices handle even asset-heavy pages with ease and don't struggle when navigating through them. That said, whereas both devices rely on Chrome for your browsing needs, Samsung's Galaxy S6 edge comes with its own default solution that is an equally great performer.

Honestly, the only thing separating the experience is just the incredible amount of detail produced by the Galaxy S6 edge’s display. Certainly, we have no qualms or complaints about the amount of detail presented to us by the Xperia Z3’s display, but once you’ve seen the sheer enormity of what quad-HD resolution delivers, it’s hard to ever go back to visualizing webs sites in their entirety on a 1080p resolution screen.



On the connectivity front, you'll hardly find much to complain about, regardless of whether you go for the Galaxy S6 edge or the Xperia Z3. Both devices offer support for a wide array of LTE bands, 5GHz Wi-Fi, Bluetooth (4.0 for the Xperia Z3, 4.1 for the Galaxy S6), NFC, DLNA, and MHL. Still, the Galaxy S6 edge pulls ahead because of its infrared blaster for control over home electronics, and Samsung Pay – the company's new mobile payments solution that works hand-in-hand with the handset's NFC chip.

The idea behind it is much alike to that of Apple Pay – the company gets retailers and banks involved (but free of charge), and you reap the benefit of never having to pull out your credit card out of your wallet again (much less physically sign any receipts).

Camera

Fantastic looking photos are snapped by the two, but things just look better with the Galaxy S6 edge camera.

Sony's flagship sports a 20.7-megapixel 1/2.3” Exmor RS sensor, and Sony touts the new 25mm G Lens optics (f2.0), and other changes under the hood, such as boasting up to 12800 ISO sensitivity. Meanwhile, Samsung's Galaxy S line has always been synonymous with great camera quality, and the company wasn't about to drop the ball with the Galaxy S6 edge. Instead of focusing on the software side of performance, Samsung has taken a two-pronged approach by making sure to deliver some exciting hardware updates, too. To that end, the Galaxy S6 edge's 1/2.6”, 16-megapixel rear camera comes with a wider-than-before f/1.9 aperture lens and an optical stabilization gizmo attached to it.

The selfie snapper, too, has received a commendable update, and now offers 5-megapixels of resolution and an equally wide, f/1.9 aperture lens – whereas the Xperia Z3 is outfitted with a pretty ordinary 2-megapixel shooter. The handsets are adequately fast to shoot and record a snap, with Samsung's Phase Detection Autofocus System giving it an edge here, while the Xperia Z3 has a dedicated shutter button to the scale, so you can take a photo from a locked screen in a second or two.



Both phones produce high-quality photos, worthy of being converted to 4” x 6” printouts – and even larger layouts because of the amount of detail they capture. Combing through the results, ones captured outdoors where sunlight is plentiful, we’d give the Galaxy S6 edge the slight, minor advantage in overall quality. In particular, its warmer color reproduction makes our snapshots livelier in tone, whereas with the Xperia Z3, it exhibits a profound cooler tone; bluish in tone and sometimes washed out too. The cooler production is more prominent indoors under artificial lighting – florescent to be exact.

Even though the qualities rival one another when lighting is abundant for the most part, it’s the Galaxy S6 edge that shows its worth more under lower lighting conditions. For starters, its f/1.9 aperture lens proves most useful in capturing more light – so not only do photos comes out marginally brighter, but it’s still able to maintain a decent amount of sharpness and detail in the process. Oppositely, the Xperia Z3 takes some reasonable images, but there’s a little more noise with its composition. Going with their respective flashes, the Z3’s flash is a tad bit more powerful, garnering warmer toned colors for more vibrancy – while the S6 edge’s is more on the neutral side.




Both handsets can record 4K video at 30fps, as well as 1080p footage. The videos come out detailed enough, with good color presentation, and no skipped frames. Sony's digital image stabilization, called SteadyShot, performs almost as well as a mechanical OIS system, but the checkered flag still goes to the Galaxy S6 edge when it comes to overall performance. In addition to the sharp looks, focusing it smoother and audio recording has a more robust tone with it – whereas with the Z3, its sharper toned.

Multimedia

We have no complaints about the multimedia prowess of both phones.

Both galleries offer grid thumbnail views, and allow for rich picture editing from within the apps, as well as sport plenty of sharing options. Best of all, there are enough fun editing tools at their disposal to further enhance the look of photos. Video playback is excellent on both handset, too, as they support quite a handful of video codecs out of the box. Watching videos isn’t an issue with either of them, thanks in part to their sharp displays, but we have an extra layer of multi-tasking with the S6 edge’s experience – videos can essentially be played in their own windows, which can be placed on top of whatever we’re doing.

When it comes to the music players, we'd have to give one up for the Xperia phone, as it has a much sleeker and more comfortable interface. Both Z3's Walkman player, and Samsung's TouchWiz one have plenty of equalizer and visualization options built in, but the graphical environment on the Sony looks much more stylish than the reserved Samsung UI.


The Xperia Z3 also flaunts Sony's Digital sound Enhancement Engine (DSEE), which brags to upconvert crappy tracks to a higher-resolution format – we can attest that there is a slight difference, though not as stark as if the tunes were high quality in the first place. Sony offers two waterproof stereo speakers at the front, which sound clean, but are somewhat muffled, while the Galaxy S6 edge only offers one speaker along the bottom edge, which is strong enough, but with a thinner and subdued quality.

Call Quality

Neither one impressed us enough more than the other when it comes to call quality, so it’s pretty much a dead-tie in this category. The more we think about it, the more we come to the undeniable conclusion that they’re simply average in this particular area. Sure, their earpieces emit enough volume to make out voices in noisy environments, but there are some displeasing qualities about them that are audible – like how there’s a hiss to voices using the S6 edge, while the Z3 has a muffled tone.

Battery

Most likely related to its beefier sized battery, a 3100 mAh one, the Sony Xperia Z3 delivers a longer tally in our battery benchmark test. In fact, it musters up a total time of 9 hours and 29 minutes from a single charge – whereas the S6 edge’s smaller 2600 mAh battery inches out at a respectable 8 hours and 11 minutes. Still, it has to be noted that the S6 edge ran our battery test at a slightly lower display brigthness, due to software limitations in TouchWiz. In practical day-to-day usage, however, we find their batteries to provide the usual 1-day of juice with normal usage.

Even though the Xperia Z3 has the endurance, it requires an exorbitant 235 minutes to fully charge its battery. Time isn’t always on our side, so it’s quite refreshing to know that the S6 edge’s rapid charging system gets it juiced in no time at all – an impressive 83 minutes to be exact! Additionally, if charging via the usual microUSB cable isn’t your thing, the S6 edge also has the convenience of being charged wirelessly.

Conclusion

Right off the bat, there’s something to say about a smartphone that’s just beginning its life. From the specs standpoint, the Samsung Galaxy S6 edge clearly has a lot to offer over the Xperia Z3. Comparing the two on paper, it’s almost a knock out for the newer Galaxy S6 edge, not only for its cutting-edge specs, but also for the tremendous effort on Samsung’s part to deliver a premium looking smartphone.

However, as we’ve experience several times, specs alone don’t dictate a phone’s true performance – and the Sony Xperia Z3 proves that in this particular comparison. True, its hardware is older and not quite as pushing the boundaries as its rival, but nevertheless, the end result is a smartphone that impresses on several fronts. Solidifying things even more, it’s one of the few remaining flagship smartphones to offer true water-resistant protection against submersion, which is something it has over Sammy’s new pride and joy.

From a cost standpoint, all fingers point to the Sony Xperia Z3, which, at this point, can be grabbed at a fantastic discount if you search in the right places. To be fair, though, the lower cost attached to the Xperia Z3 now makes perfect sense, as the Xperia Z3 has been on the market for some time. Conversely, the Galaxy S6 edge has just recently become available, so it’s going to cost a pretty amount to pick up at the moment.

Of course, the mounds of money you fork over to pick up the Galaxy S6 edge is worth it, as it’s an impressive thing that’s best experienced up close and personal – albeit, the Xperia Z3 is still worth a shot even now, more so if you’re all about savings.
