The OnePlus 3T has just joined the world of flagships. Does it have enough to take on the most popular smartphone of the moment, the Samsung Galaxy S7 Edge? Let's tackle this question by looking at what these two devices have in common, and what makes one better than the other.

OnePlus 3T vs Samsung Galaxy S7 Edge: design and build

The OnePlus 3T is an enhanced version of the OnePlus 3, but in terms of design there are no visible signs of improvement: the design is exactly the same. The device measures 152.7 x 74.7 x 7.35 mm with a weight of 158 g, all within an aluminum unibody frame.

Samsung offers a model with relatively similar dimensions: 150.9 x 72.6 x 7.7 mm. Despite the combination of metal and glass, it weighs slightly less. In other words, the Galaxy S7 Edge is smaller and lighter, but thicker.

Both devices are very elegant. I find the Gunmetal (dark grey) color of the OnePlus 3T very chic, but despite its premium appearance, the smartphone remains somewhat “classic”. In saying “classic” I don’t mean anything negative. I simply think that the Galaxy S7 Edge has more to distinguish itself from its closest competitors: the curved screen edges ensure that holding the device is comfortable, and more notably, the IP68 certification protects it from water damage (30 minutes at a depth of one meter) and dust. Samsung is also planning on launching a new S7 Edge black color, heavily inspired by Apple’s jet black iPhone.

In defense of the OnePlus 3T, it does have an interesting feature which sets it apart: the use of a Type-C USB port. Practically speaking, this does not make a big difference. The S7 Edge still has a rapid charge function despite its microUSB port, but we’ll get to that later.

In conclusion, it is often a question of taste and interest. The Galaxy S7 Edge offers more, so it’s up to you to decide whether its waterproofing and curved edges are determining factors.

OnePlus 3T vs Samsung Galaxy S7 Edge: screen quality

Again, OnePlus has not really done much in the way of innovative design. We find the same screen as on its predecessor: AMOLED (optical), 5.5 inch, Full-HD definition (1,080 x 1,920 pixels). The pixel density is 401 ppi, with a maximal luminosity of 482 cd/m².

The Galaxy S7 Edge has a Super AMOLED screen, measures 5.5 inches, and has a QHD definition (1,440 x 2,560 pixels). The pixel density is 534 ppi and the maximal luminosity is 653 cd/m². The best thing about this, as we described before, is the curved edge around the screen. This screen has been indispensable for some, and useless for others. Here, individual preferences and habits will ultimately dictate people's choices. 

For the same screen size, the S7 Edge offers better definition, so the pixel density is obviously much higher. Since both devices have AMOLED, they could both easily take advantage of the advantages of this technology (black on the screen doesn't have to be lit up which saves energy). The S7 Edge does go a little bit further with its 'Always On' mode, permanently displaying the date, notifications and other elements in a white on black backdrop on an otherwise switched-off screen.

Regarding screen quality, here both devices both put on a good show. That said, I’m more inclined towards the sRGB mode with the OnePlus 3T, which has a more realistic color display and makes it much more pleasant to look at. Either way, the visual angles on both phones are good and the ambient luminosity does not interfere when you read from the screen.

OnePlus 3T vs Samsung Galaxy S7 Edge: user interface

Here, two schools of thought clash. On the one hand, we have OxygenOS 3.5.1, which is based on Android 6.0.1 and is relatively “pure”, in terms of Android. On the other hand, we have Samsung’s TouchWiz overlay, which is also based on Android 6.0.1 Marshmallow.

Though things may seem similar at first glance, they are actually very different in practice. Graphically, most of the icons are rounded on the S7 Edge, whereas the OnePlus 3T has no problem displaying different shapes. In addition, OxygenOS is similar to Stock Android, so the menus are relatively similar and we can clearly see the influence of Nougat. TouchWiz, on the other hand, has changed a lot in the past two years but still has, for me at least, some notable flaws, such as its choice of garish colors. Having said that, the interface is still intuitive. The good news is that the two devices should receive Android Nougat very soon.

Each device offers specific software functions. The Galaxy S7 Edge exploits the potential of the curved edges with the EtiquEdge function that allows the organization of launch and information (time, information etc) buttons. The OnePlus 3T, on the other hand, offers a kind of Shelf/Never Settle launcher that provides access to memos, apps and recent contacts, as well as the weather and various widgets. A few small OnePlus 3T advantages: the night mode provides screen color modification to prevent from tiring the eyes, the potential to personalize (dark mode and dominant color), and no bloatware.

This means that, as a gamer, you will probably appreciate the inclusion of the “Game Launcher”, a Samsung feature specifically adapted for gaming. You can use it to pause the device in order to focus all the power towards the game’s graphics, saving your progress, activating a “do not disturb” mode, taking a screenshot or video...

OnePlus 3T vs Samsung Galaxy S7 Edge: performance

The OnePlus 3 was a benchmark in terms of power, surpassing even the S7 Edge. The OnePlus 3T goes a step further in surpassing its competitors by including Snapdragon 821 (two cores at 3.5 GHz and two at 1.6 GHz), an Adreno 520 graphics chip and no less than 6 GB of RAM. The S7 Edge, in contrast, uses less modern hardware: a Snapdragon 820, four cores at 2.3 GHz, four at 1.6 GHz, and 4 GB of RAM.

One slight advantage the OnePlus 3T has is that its Gunmetal color model also includes up to 128 GB of internal memory. That said, don't jump to the conclusion that the OnePlus 3T is a more interesting device than the S7 Edge. The latter allows the use of a microSD card, this isn't possible on the OnePlus 3T.

For daily use, both devices are sleek and show no signs of slowing down, so it's impossible to really distinguish between them. This means, in terms of benchmarks, the Chinese smartphone has big advantages, with Google Octane being the only exception to this rule.

Samsung Galaxy S7 edge 1976 2362 30310 5077 10292

The SAR of the OnePlus 3T is 0.995 W/kg (head) and 0.645 W/kg (body), that of the S7 Edge is 0.62 W/kg (head) and 1.06 (body). The US variant of the Samsung Galaxy S7 Edge is clearly worse in this case.

OnePlus 3T vs Samsung Galaxy S7 Edge: camera

The Galaxy S7 Edge is one of the best smartphones around to take photos with. On paper, it has a 12 MP camera with an aperture of f/1.7, all linked with dual-pixel technology that allows for good shots of moving subjects. The optical stabilization is on point, so in short, it all sounds great…. In practice, it meets these expectations.

The OnePlus 3T has a 16 MP front camera with an aperture of f/2.0. It has no dual-pixel technology or double lens, nor any other modern or revolutionary technology, so ultimately it is just a camera that does the job. As for stabilization, however, it includes both an optical and an digital system.

Although the OnePlus 3T camera is good and provides very accurate results, the Galaxy S7 Edge is no less superior, since by and large it produces better results and comes out the winner in comparison. It must be noted though, that OnePlus has improved its front camera, using a 16 MP lens (with an aperture of f/2.0) while Samsung uses a 5 MP camera on the front of the S7 Edge. Still on the topic of front cameras, the size of the pixels is also bigger (1.34 µm) in the S7 Edge compared with the OP3T (1 µm).

OnePlus 3T vs Samsung Galaxy S7 Edge: battery

For its phablet, Samsung decided to use a battery with a capacity of 3,600 mAh - hardly surprising for a screen of that size. OnePlus chose not place the bar quite so high with the OnePlus 3T, using “only” a 3,400 mAh battery. This means that it has 400 mAh more than its predecessor without having made the slightest change in design, so all in all it's quite a feat.

Of course, battery capacity is not everything and software optimization must be taken into account. The result is compelling in both devices: they can go a whole day (or even two if you do not use it much) without needing to be recharged.

Charging is fast for both models. The OnePlus 3T uses the Dash Charge system (5 volts 4 amps) which allows for very rapid charging - though I managed to get from 5 percent to 57 percent in 30 minutes. The S7 Edge also has a rapid charging system (Quick Charge 2.0), going from 5 percent to 43 present in 30 minutes as well.

OnePlus 3T vs Samsung Galaxy S7 Edge: the verdict

It's hard to say which of these smartphones is truly the best. The OnePlus 3T is much more recent so obviously, it has better hardware, but what is clear is that the Galaxy S7 Edge ages well and is more than able to stay in the running. Sure, it falters a little in terms of performance, but its design stands out from the competition and it offers various features that its competitors do not.

Another element to take into account (and not a little one!) is the price of the smartphones. The actual price of the OnePlus 3T is a maximum of $599 (for the 128 GB version). The average price of the S7 Edge on Amazon is around $616 for the 32 GB version (but with an SD card). If your budget is tight, this could solve the problem for you.

    Undoubtedly the S7 edge is a legendary invention during its occupied, but one has to agree that the 3T is indeed manage to out-run the S7 thanks to its more advance chipset and processor--Snapdragon 821 is super, when supported with 6GB RAM it will be the insanely powerful smartphone that NEVER SETTLED throughout the whole year till maybe 2019. (*Looking in terms of "Price:Performance" ratio, the 3T can easily "triple kill" the S7 edge with no doubt.

    I feel you were a bit biased in favour of OnePlus 3T in at least two counts: screen and TouchWiz. Whilr you listed better display specs of S7 Edge, still leaned in favour of 3T. Also, you can say lots about Touch Wiz, but it has evolved to become one of the best frameworks, with great functionality, design and esthetics, especially in Nougat.

    • David Roberson Apr 21, 2017 Link to comment

      The screen lean was explained. Touch Wiz is OK. I've had a lot of Samsung products but I'd prefer a more vanilla version of Android. Not having bloatware is a huge plus. Lots of people work on their phones to install a regular non-bloat version of Android. Very few want to install Touch Wiz.

      I can agree with your screen comment. The S7 Edge has a better screen but the implementation on the 3T was better for the reviewer.

      I can't imagine anyone would agree on Touch Wiz.

    Both phones are good but for me the Quad HD display and features such as water resistance, wireless charging and customising the edge with all my shortcuts not to mention the extremely good battery life has me sold on the s6 edge.
    My major consideration in buying a phone are the features and battery life, both of which are richer in the S7.

    How did you find out the SAR values for OP3T? I asked their spport service about this and they didn't have the answer. Are the values mentioned in the article FCC or EU values?

    • Bastian Siewers Dec 2, 2016 Link to comment

      Hi! Those were the EU ratings found in the small booklet that came with the OnePlus 3T. We changed the values in the article to the ones by the FCC.

    Glad there are other choices than these two. These get trotted out as the best phones a lot, but there are more interesting phones than these for what I want in a phone.

    • Loie Favre Dec 5, 2016 Link to comment

      Hey! You're right, there are a lot of good phones out there. What would you say is your top pick?

    • Alex Hogg Mar 30, 2017 Link to comment

      I agree. Personally, I'm loving the Honor 8 at the moment.

  • Andrew Burgin Dec 1, 2016 Link to comment

    Samsung gamble once not offering the micro sd card on there Galaxy S6 phones plus Note 5 and there sales weren"t so good,so with OnePlus not offering the memory card it might not be the right choice to get consumers to try there phones out,o.k Apple seem to get away with not offering the memory card slot, but Apple as been around for bit but One Plus as not

    • Peter Abou Gharib Dec 3, 2016 Link to comment

      Apple gets away with it because their memory options are bigger. 32, 128, 256 vs 32, 64 on most androids.
