OnePlus 5 vs Samsung Galaxy S8: Can You Guess The Winner?

The smartphone makers in any corner of the globe work on different models in a year. This is done to diversify their income by offering products from different categories. This logic is old as time, and it has proven its efficiency a long time ago. So, it’s useless to discuss it now. But what about those brands that do not follow this ‘rule’, and come in only with one smartphone? Say, what about the OnePlus? Even Apple launches more than one devices per year. So what benefits are hidden under this strategy OnePlus blindly follows to? To understand this we have to compare its latest flagship (or maybe we have to say its only phone) with a corresponding device. We’d like to make this comparison with the Xiaomi Mi 6, but the latter is not sold aboard. So we decided to compare the OnePlus 5 with the Samsung Galaxy S8. I guess no one will mind if I say these are the most powerful Android-running handsets nowadays if taking into account both of them are packed with the Snapdragon 835 chipset.

A quick look at the specs comparison table will make us think the OnePlus 5 is the way better than the Samsung Galaxy S8. I mean the hardware features of the fifth-gen OnePlus flagship look more attractive. But we know sporting good hardware doesn’t mean providing good performance. So let’s start comparing these amazing flagships to understand which philosophy is better – launching only one flagship per year or releasing myriads of phones and a few too powerful models among them.

OnePlus 5 vs Samsung Galaxy S8: Appearance

The OnePlus 5 comes with an all-metal design with rounded corners. The back of the phone has passed a sandblasting process for better ergonomics and smoother feel. Apart of this, the device comes with a thickness of 7.5mm and weighs only 153 grams. This is not the thinnest and lightest smartphone we have ever seen, but it still looks and weighs airy if taking into account we are dealing with an all-metal smartphone.

As for the Samsung Galaxy S8, the design is completely different. It comes with a bezel-less screen, metal frame and glass curved back panel. Thanks to a number of production processes the S8 provides excellent ergonomics. Moreover, the frame and the glass come in the same color providing an overall strong visual effect.

The OnePlus 5 sports a 5.5-inch AMOLED screen at a resolution of 1080p. This is enough not to complain of its display, but we have to state many mid-range smartphones feature such a screen nowadays. Anyway, the flashlight, a 16MP shooter, and proximity sensor are located above the screen. The unpressable Home button with a fingerprint recognition feature is placed below the display.

The Korean manufacturer’s flagship differs from all smartphones in the globe by its design. Especially this refers to the front panel. It comes with a 5.6-inch 2K resolution AMOLED screen. But what’s more amazing Samsung has adopted curved and bezel-less screen design and seems all of its upcoming flagships will use it in the future. However, the screen of the Samsung Galaxy S8 is really something and it’s reasonable it affects the phone’s pricing. Though this device is not still capable of competing with border-less handsets such as the Xiaomi Mi MIX, the S8’s screen occupies 83.6% of the overall front panel. This means there are no buttons on it.

The back side of the OnePlus 5 has been talked too much. Many think it copies the iPhone 7 Plus design. And there is a grain of truth in this statement. But if comparing with the previous model the OnePlus 5 looks more modern. Agree the OnePlus 3 / 3T look roughly. Although it doesn’t prevent the company from selling millions of them. Anyway, the current model comes with a metal back panel with a double-U shaped antenna design. There is also a dual-camera on the upper left corner with a flashlight next to the sensors. The latter are circled with a special metal frame to protect the lens. The OnePlus logo is placed in the middle.

Unlike the futuristic and super-modern front panel, the Samsung Galaxy S8 has a traditional rear panel similar to all Galaxy-line handsets. It uses a glass material, which provides more pleasant feelings when holding. Moreover, it looks like a chameleon that changes colors under the light. Agree this visual effect has become a mainstream for the top brand phones such as Xiaomi Mi 6, Huawei Honor 9 and so on. The phone carries a flashlight, single-camera and a fingerprint scanner on the back. But who puts a fingerprint scanner on the back nowadays, Samsung?

As for special keys, the OnePlus 5 comes with a three-stage switch key like the iPhone, while the Samsung Galaxy S8 sports a Bixby button with Samsung’s own-developed smart AI.

Verdict: The OnePlus 5 has decided to change the appearance of the third-gen flagships we used to see. As I said, many have been accusing the company of bringing an iPhone-like design. This is true, but the market is full of such handsets. This simply means people like it, and there is nothing bad to use a friendly look. What has Samsung done? It has worked a lot to come in with a revolutionary and very stylish front panel. Probably it’s the main selling point of this device. I mean not only the appearance but the screen, generally. Unfortunately, the Korean manufacturer couldn’t come in with an interesting back panel. So, personally, I have a feeling the front side of the phone is too innovative, while the rear panel looks backward.

OnePlus 5 vs Samsung Galaxy S8: Camera

One of the key features of the OnePlus 5 is considered to be the dual-camera with ‘wide-angle + telephoto’ lens. The wide-angle main sensor carries a model number of Sony IMX398. It comes with 16MP of graphic resolution, f/1.7 aperture, and 1.12 microns of pixel size. The second sensor comes with Sony IMX350 model number, 20MP graphics resolution, dual-core focus support as well as EIS (Electronic Image Stabilization).

The camera app remains almost the same in comparison to the elder models, but there are a few changes to correspond to the dual-camera features. Say, now the camera software on the OnePlus 5 offers 2x zoom button or watermark options.

The Samsung Galaxy S8 didn’t sport a dual-camera, but it is capable of providing great shooting experience. It comes with Sony’s custom IMX333 CMOS camera that comes with 12MP graphic resolution, f/1.7 aperture, full-pixel dual-core focus, and OIS (Optical Image Stabilization).

As for the camera UI, Samsung phones come with its own Samsung Experience Interface, which has got tons of updates recently. As a result, there are left only those features that are used the most.

Sample Photos: OnePlus 5 vs Samsung Galaxy S8

Verdict: Though the OnePlus 5 can have an advantage due to a dual-camera, both models come with Snapdragon 835’s ISP image processor. Thus they have all chances to provide crazy camera experience regardless the sensors. On the other hand, two lenses on the OP5 show provide better photos in terms of saturation, color adjustment, details, and brightness. But the Samsung Galaxy S8 is better in terms of contrast, sharpness and noise control. Finally, the OnePlus 5 is great in macro shots, while the S8 takes better night shots.

OnePlus 5 vs Samsung Galaxy S8: Software

UI is a decisive factor for many experienced smartphone users. Say, I can’t use another handset but Sony. I guess most of you are obsessed with UIs of this or that brand as well. So what the manufacturers have to do? They try to come in with better and smoother performance. Generally, there are too many smartphone makers, but only a few of them have developed their own UI. Say, Xiaomi’s MIUI is one of the most popular systems in China. In this sense, OnePlus’ Hydrogen OS is a worthy competitor to any OS. But because of appearing only on one model, it’s not popular.

Hydrogen OS 3.5

Samsung Experience 8.1

However, the OnePlus 5 comes with a custom Hydrogen 3.5 based on Android 7.1.1. It provides tons of improvements, though many of them will be useful for Chinese users. On the contrary, the Samsung Galaxy S8 runs on Samsung Experience 8.1 based on Android 7.0. It’s one of the most spread UIs in the world due to millions of units sold every year.

OnePlus 5 vs Samsung Galaxy S8: Performance

As I said at the beginning of the article, both models sport Qualcomm’s latest chip named the Snapdragon 835. It’s a 10nm process SoC paired with Adreno 540 graphics processor, Spectra 180ISP, and Hexagon 682 DSP. Apart of this, the Snapdragon 835 supports 2×2 MIMO dual antenna lineup, which means it can send and receive data packets via two antennas simultaneously. Plus, the signal receiving capacity has increased by 100%.

Back to the key features, the OnePlus 5 is packed with the full-blooded version of the Snapdragon 835. The latter is paired with 6/8GB of RAM. As for the Samsung Galaxy S8, it uses the downgraded version of Qualcomm’s processor, and the memory is only 4GB. While you can think this phone will yield in terms of performance, Samsung (and we as well) have to say, the process technology is the same, and thanks to a smaller memory, it will decrease the power consumption.

To find out how the SND835 versions affect the performance let’s test the devices via benchmarks.

The results are expected, though many will be disappointed with them. However, we have what we have. But what’s amazing Samsung’s Experience OS occupation by resources is the way higher than OnePlus’ Hydrogen OS. In other words, the system puts more efforts to provide what we need, but the 4GB RAM is enough for it. As for the OnePlus 5, it works quietly without many efforts.

OnePlus 5 vs Samsung Galaxy S8: Battery

We have already come in with a charging test of these handsets. But we have to take a closer look at the charging/discharging features in this article.

The OnePlus 5 is packed with a 3300mAh battery, while its competitor comes with a 3000mAh battery. Seems this capacity shouldn’t be sufficient for a daily use if taking into account the experience of other handsets. But we have to remember they are packed with a 10nm process technology chip, that means the overall power performance is controlled better.

To learn how they behave we have made a four-hour test for both devices.

After four hours the OnePlus 5’s power was remaining at 56%, while the Samsung Galaxy S8 showed 48% of power. Though the latter consumes the power faster, both devices will provide a heavy daily use with no problems.

Well, the test shows the OnePlus 5 is better in terms of power consumption. But we know it does not only matter of battery capacity. Do you remember the Samsung Galaxy S8 sports a 2K screen? Do you know screens consume power the most? So it’s quite reasonable why Samsung’s representative consumes more.

Well, as everything is clear with discharging, let’s take a look at the charging process. The OnePlus 5 supports DASH fast charging technology, while the S8 supports QC2.0. The latter has caused a stir around it, but we have what we have.

As for actual test results, the OP5 charges in 76 minutes, while it takes 98 minutes to charge the S8 fully.

Verdict: The advantages coming our way from DASH technology are obvious.

The Final Words

When talking about the top brand flagships, many say the Samsung Galaxy S8 is the only worthy rival to the iPhone 7. Of course, Samsung is the world leader in terms of smartphone sales, but does this mean it launches the best devices? This simple comparison showcased the OnePlus 5 is the way better than the Samsung Galaxy S8. Though both devices come with the latest creation of Qualcomm, they provide quite different performance. Moreover, the OnePlus 5 is priced lower than its competitor. So it turns out top brands like Samsung sell millions of units of their smartphones due to a good marketing campaign and brand popularity. On the contrary, brands like OnePlus usually come with outstanding devices, but they can’t appear on the top ten lists.

As for these phones, the Samsung Galaxy S8 has only one selling point – it features a 2K AMOLED screen, which (almost) has no borders, and it’s double-curved. The rest of the S8 doesn’t attract at all. OnePlus has worked much to enhance many features such as design, camera, performance, memory, battery and so on. So it’s quite reasonable why it can beat the Galaxy S8.

P.S. Though the OnePlus 5 is a winner in this comparison, it has no chances against the Xiaomi Mi 6. If you doubt, look at the innovations this handset comes with.
