Vivo X51 5G, contact and first impressions


The live Chinese company lands in Spain and does so through the big door with a mid-premium smartphone with top smartphone features, the live X51 Pro. It is a mobile with a design reminiscent of Huawei's P30 Pro with a great effort in innovation in the photographic section.

It is difficult to differentiate yourself in a mid-premium and top range mobile market. Almost all mobiles look the same, they differ by two technical characteristics that equal the majority of the public and perhaps slightly in the software layer.

Vivo X51 5G comes to market for 799 euros, halfway between what we can call high-end and top-end that already exceeds 1,000 euros.

It is a very balanced mobile in most facets and where it stands out most is undoubtedly at two points in how it has risen to the current trend in terms of screen, curved on the sides and AMOLED with a high refresh rate (90 Hz), and how it has solved the rear photographic system that includes a stabilized 5X zoom sensor, a wide-angle sensor and a 48 Mpx main sensor with very advanced optical stabilization.

We have been able to spend a week with him and we have already got an idea of what this mobile is capable of, we offer you our impressions and opinion after this complete contact.

In a few days, we will finish performing all the laboratory tests to it, including some vibration and movement tests for the gimbal, which first of all, has convinced us a lot, as you will see in the section of the camera.


 Huawei P30 Pro Restyling with a Screen on Steroids

The design of this vivid X51 5G is very reminiscent of the one we saw on Huawei's P30 Pro last year for several reasons. The first one is that curved screen on the sides attached to the back that also curves leaving asymmetrical profile.

The top and bottom are flat as they were on Huawei's mobile. Below is a video of the design of the same coupled with a comparison with the model we are discussed.

It is a mobile that weighs 181 grams and this is partly thanks to that 6.56" AMOLED screen from Samsung and the 4,315 mAh battery that integrates the terminal.

Let's talk a little about that screen, 6.56 inches diagonal with an unusual resolution, albeit FullHD+, 2,376 x 1080 px which gives a 19.8:9 aspect ratio. It is a Samsung AMOLED panel that offers a good brightness although we need to make additional measurements in the lab we will surely go from 650 lux to maximum brightness.

This panel supports HDR10+ content and certainly in this mode we see much higher brightness peaks. Calibration is not bad and allows us to work in dark mode and even both in 90 Hz mode that gives extra fluidity and 60 Hz that has a lower power consumption.


Once you take it in hand it does not give the feeling of being heavier than by its size you would expect so good work on the part of life.

The back has a matte finish, nice and discreet with the prints, something to thank. Although the company offers a transparent silicone case in the packaging for added protection.

The front camera is integrated into the screen, in the upper left and if we turn the terminal we see that island of the rear cameras in the same situation. It's like a double-height island where we see the 5X zoom sensor at the bottom while the rest of the cameras are on the black side.

The LED flash system is located outside that island to the right of the entire pack at the height of the back of the mobile that was and this only stands out for showing the company logo screen-printed on the bottom left.

In terms of buttons, the design is very clean as we have both volume buttons on power on and all of them on the right side of the terminal.

One thing that has caught my eye is how low the screen print reader is compared to other mobiles. However, we have been able to verify that it works very well and better even in combination with facial unlocking.


Fluidity and solvency for the vast majority of users

During our week of use, we have been testing the latest software version available at launch and it is Android 10 with the FunTouch OS 10 customization layer (PD2005F_EX_A_3.10.12).

One thing we used to bump into when testing mobile brands coming from China where the layers of customization that used to be very recharged. The case of this live mobile could be taken as an example to follow since the customization is very low, we do not have bloatware beyond a mobile management application. The feeling of use and fluency is very similar to the feeling we have with a Google Pixel.

We haven't had any problems with slowdowns or forced app shutdowns, and in fact, we haven't seen any incompatibilities in more advanced features like that dark mode implementation or even NFC payment.

It is true that at the price of 799 euros you would expect mobile to mount already the highest-end processor available, however, this live X51 5G stays on a Snapdragon 765G and that, on the one hand, is not so bad news.


It is noticeably slower in benchmarks than the Snapdragon 865 or its plus version up laps but in the day to day, the sensations are not as exaggerated as those figures. The Snapdragon is a very capable chip with sufficient graphics performance for this resolution in demanding games like Call of Duty or Asphalt as we have seen on mobiles like LG Velvet or the Mi 10 Lite.

It is accompanied by 8 GB of LPDDR4x RAM that will allow the use of multitasking and applications in the perfect background to be able to have applications that do not close and it is something that we can quickly manage from the multitasking screen blocking the ones that we want not to close the system.

One point we didn't like is the internal memory, although in capacity it is perfect with 256 GB the memory type is UFS 2.1 and of course, it falls behind models with UFS 3. The limitation comes in terms of reading/write performance and where you notice that difference the most is in installing applications or loading heavy games.


Very versatile camera pack with optical stabilization that looks like magic

The camera is one of the big claims when purchasing a mobile phone and this is where the spec clippings we've seen in other sections have been used.

We have a 32 Mpx front camera with fixed focus embedded in the screen and it highlights how well you can manage the backlights thanks to its HDR mode. But this is not the strongest point and it is that we are facing a very complete rear camera pack.

It is worth noting that the stabilization system that we have not seen until now on other mobiles. Optical stabilization usually brought with it a substantial improvement as it was a physically real-time lens correction.


The X51's Gimbal system works rather as an advanced optical stabilizer system that allows vibrations and tremors to be multiplied by four times that could eliminate traditional optical stabilization.

To get an idea, it's as if the optical system on the sensor is floating over it and could compensate for movements on the axes of the mobile.

That results in a recording mode that is very stable even recording in one hand. This mobile can record videos of up to 4K resolution. Here a sample running with his cell phone in one hand and practically at night.
