which one is the best smartphone?


Realme and OnePlus may be owned by BBK Electronics, but both brands offer independent products. This is what we will see by comparing the OnePlus 8 and the Realme X50 Pro, offered in France at close rates.

OnePlus continues to increase its prices little by little and the latest, the OnePlus 8, is no exception. Once known as the creator of the flagship killer, it now has to deal with the Realme X50 Pro 5G sold cheaper with rather similar features. Let’s more precisely compare the two smartphones together.

Design: one or two punches

By far, the OnePlus 8 and Realme X50 Pro take up the standards of smartphone design in 2020 with a screen Borderless, pierced at the front camera. The two devices already stand out at this element, with two front cameras for the Realme X50 Pro, compared to only one for the OnePlus 8.

Visually, the difference is also made at the back of the phone. The vertically elongated photo module was placed in the center on the OnePlus 8, rather than in a corner like the Realme X50 Pro.

Neither smartphodoes not offer a certification of water and dust resistance.

On this criterion, neither smartphone really stands out. They both offer a good experience, without being among the best on the market.

AMOLED slab at 90 Hz

It has been said that the OnePlus 8 features a 6.55-inch screen compared to 6.44 inches for the Realme X50 Pro. On paper, this is the only difference between the screens of the two smartphones, both of which offer a 2400 x 1080 pixel AMOLED slab, protected by Gorilla Glass 5 and certified HDR10 with a refresh rate of 90 Hz.

Unfortunately, due to the containment we were not able to perform an accurate screen test of the Realme X50 Pro 5G. It can still be indicated that the screen is perfectly readable in the sun, while offering a level of absolute contrast. The white balance seems a little too cold, it is often the case of phones in this range that do not benefit from the calibration level of the best smartphones on the market.

On the other hand, we were able to test the onePlus 8 screen in detail. On this criterion, the smartphone impresss with its coverage at 100% of the color space DCI-P3 with an E delta of 3.13 almost imperceptible to the naked eye. In addition to the infinite contrast, you get a maximum brightness of 790 CD/m2 guaranteeing a perfect reading, even in the sun. Here too the white balance pulls a little cold, but the activation of the DCI-P3 mode in the settings of the smartphone is enough to correct this defect.

On this criterion we will therefore select the OnePlus 8 that has proven itself, bearing in mind that we were not able to pass the same test at the Realme X50 Pro which does not seem to demerit.

Realme UI or Oxygen OS: the choice is quickly made

The OxygenOS interface offered by OnePlus has long been one of our favorite interfaces in Frandroid. The manufacturer regularly offers updates for this interface close to That of Google visually, but with many more features, all very well integrated. During his test, Manu was particularly seduced by this element of the smartphone, but still notes a small problem calibration of sensitivity with navigation by gesture.

The OnePlus 8’s interface is full of options

The Realme X50 Pro integrates Android 10 with an interface called Realme UI. Behind this name is actually ColorOS used by Oppo smartphones, another brand of the BBK Electronics group. If ColorOS, and Realme UI, had disappointed us before, the last iteration made clear progress. Without achieving the level of excellence of Oxygen OS, yet developed within the same industry group, the interface now offers a successful user experience.

Among the shadows on the board, Geoffroy notes a built-in “smart assistant” screen by default and rather useless in comparison with Google Discover. The display of notifications also leaves something to be desired because of the punch has two sensors in front of the smartphone.

On this point, our preference goes to OnePlus, although the interface proposed by Realme has made real progress.

Photo: 4 sensors are no better than 3

OnePlus and Realme have made different choices for the photo module on the back of the smartphone. Let’s start with the OnePlus 8 and its three-device module:

  • Principal: Sony IMX586 of 48 Mpx (0.8 m), f/1.75 (6P), STABILIZATION OIS-EIS;
  • Ultra wide-angle 116 degrees: 16 MPx, f/2.2;
  • Macro: 2 Mpx (1.75 m), f/2.4.

This configuration is inherited from the OnePlus 7T Pro to which the telephoto lens would have been removed.

Overall, the OnePlus 8 is doing pretty well for a smartphone of this range. Daytime photos are obviously not a problem for the camera, although Manu notes a few small excesses of the UltraShot HDR algorithm that pushes the contrasts a little too hard, which can distort the captured scene. The white balance also shows its limits when obscuand the public lights turn yellow. The night mode “nightscape” does well and does not distort the colors too much. Finally, the latest sensor is dedicated to macro mode, but, as on other smartphones offering this function, we get closer here to the gadget more than other things. Without being excellent, the OnePlus 8 is doing pretty well overall in terms of photos.

Realme has developed a 4-camera module for its X50 Pro:

  • 12-megapixel telephoto lens, 54 mm (f/2.5) equivalent, x2 optical zoom, x5 hybrid zoom
  • 64-megapixel wide-angle (Samsung Isocell GW1 sensor), 26 mm equivalent (f/1.8)
  • 8-megapixel ultra wide-angle, 15.7 mm equivalent (f/2.3)
  • 2-megapixel black-and-white depth sensor (f/2,4)

The manufacturer therefore bets on variable focal lengths that will allow to widen the field or on the contrary to make zooms.

In this game, the Realme does well when you take each sensor individually, but not when you switch from one sensor to another. It’s an element that easily distinguishes the flagship killer from high-end smartphones, the calibration of colors changes by changing devices. Geoffroy notes in particular a building that oscillates between yellow, green or blue hues depending on the camera used. The X50 Pro also displays its limitations on night photos, where it is recommended to use only wide-angle cameras or telephoto lenses. The night photo mode improves the white balance, but does not increase the level of detail that was already missing with the smartphone’s automatic mode.

The Realme X50 Pro and OnePlus 8 are doing well, without catching up with more expensive high-end smartphones. If we had to choose between the two, we would be looking at the OnePlus 8 on this criterion.

Snapdragon 865 shows off its muscles

Flagship obliges, our two smartphones use the best chip available to date, the Snapdragon 865 from Qualcomm. This already guarantees both phones to be compatible with 5G, a good point for the life of the devices. This chip is coupled with 8 to 12GB of LPDDR5 in both cases, with 128 to 256GB of UFS 3.0 storage.

Let’s not go four ways, in both cases we have the right to the best on the market. On a daily basis, both smartphones are perfectly fluid, and can take the most greedy tasks without raising an eyebrow. A game like Fortnite can launch in “epic” quality and rotates seamlessly. The two devices offer a fairly similar configuration in this area and it is difficult to separate them.

Autonomy: Who will charge their battery the fastest

The Realme X50 Pro incorporates a 4200 mAh battery. Geoffroy was convincedincubated by the autonomy offered by the smartphone, first with the automatic refresh rate, which allowed it to last more than 40 hours including 4:50 with the screen on time used with YouTube videos and web browsing. In 90 Hz mode, the smartphone does just as well, with 38 hours of battery life for about 5 hours of screen on. The 60 Hz mode saves battery, and the smartphone can then last up to 51 hours with 6 hours of screen on.

With a slightly larger battery of 4300 mAh, the OnePlus 8 should be a little better. Manu says he was able to hold on with 6 to 8 hours of screen on depending on usage. It should be noted, however, that during the containment period we have not been able to pass on to smartphones our standard test, allowing us to compare them as best as possible, and the consumption of battery at home is necessarily reduced, since the smartphone does not seek to change 4G antenna.

Autonomy is good, but the burden is an increasingly important criterion to take into account. On this side, OnePlus is content with a 30W charger quite honorable and able to charge the smartphone in less than an hour, but that pales next to the 65W charger of Realme. It can charge the device 10-100% in just 29 minutes!

Overall, despite the slightly higher range offered by the OnePlus, Realme offers, in our opinion, the best experience to use. With the Realme X50 Pro, you have a good battery life and you know that you can quickly bring the battery up with the charger.

Which one to choose?

If we take our criteria point by point, the OnePlus 8 wins almost every time with a short head. It offers a pleasant design in hand, with an optimized interface and rich in functions, first-rate performance, a very well calibrated screen and a correct camera. The Realme X50 Pro actually only exceeds it in the much faster charge of its battery. Realme’s smartphone does not demerit and also offers very good performance, or a markedly improved interface.

However, there is one important criterion: the price of the smartphone. The Realme X50 Pro is priced at 100 euros less than the OnePlus 8. A fairly large price difference that could easily offset the few advantages of the OnePlus 8 against its direct competitor. It’s hard to know if the few user experience bonuses on the OnePlus are really worth the 100 euros difference. This will obviously depend on your budget and your affinity with the two brands in question.

Both smartphones offer the same level of quality overall, so we would be tempted to advise you to turn to the cheapest of the two. To learn more about each smartphone, please see our full reviews:
