Test OnePlus 7T: one of the most powerful smartphones on the market


Cinq months after the announcement of OnePlus 7 and OnePlus 7 Pro, the Chinese manufacturer returns with a new model, the OnePlus 7T. This new model is inspired by the OnePlus 7 with 3 photo sensors, a new processor and a 90 Hz display.


Au At the time of writing, OnePlus has not yet communicated the price of the 7T, but it is easy to imagine that it should be close to that of the OnePlus 7 when it comes out (€559 as a reminder). Its direct competitors could then be theXiaomi Mi 9T Pro, the Asus Zenfone 6, theXiaomi Mi 9 or the Google Pixel 3a XL, to name but a few.

Ergonomics and design

À At first glance, the OnePlus 7T looks very similar to the previous OnePlus 7. The differences are noticeable in a few details. The mobile we're interested in today adopts a slightly larger size - it's one hair higher, about the size of a drip slot. It is one millimetre wider, but still 10 mm narrower than the OnePlus 7 Pro. In hand, the phone is relatively light (190 g).

À At the front, there is not much to be found except for a drop-shaped notch. The Fluid Amoled display has a resolution of 2400 x 1080 px and occupies about 88% of the total surface area. The fingerprint sensor is underneath, as in the previous two iterations of OnePlus.


90 Hz screen is really pleasant to use.

C 'it is when you linger on your back that you notice the biggest change. The sensors are now based on a round island - as we saw on theHuawei Mate 30 Pro, for example. The polished glass finish of this OnePlus 7T is similar to what we saw on the OnePlus 7 Pro. It is very pleasant to the touch and provides a good grip, although a little slippery at times.


Les slices are quite classic. On the right is the start button as well as a slide button to toggle between silent, vibrate and ringer modes. On the opposite side are the volume controls. On the lower edge are the USB-C port, a speaker and a slot for up to 2 SIM cards.


Comme the two previous models, the OnePlus 7T does not have a 3.5 mm mini-jack socket. There is also no adapter supplied to connect your favorite headphones. You will therefore have to use USB-C headphones or prefer the use of a Bluetooth device.

Chose rare, it's two speakers (one on the bottom edge and the other just above the screen) that deliver a rather good sound, close to what we have seen on the Pro version of OnePlus 7.

Avec With its 7T sound, OnePlus brings 90 Hz to a more affordable terminal. And let's say it from the outset, the proposed slab proves to be of excellent workmanship. With a diagonal of 6.55 inches, it displays in 2,400 x 1,080 dpi for a resolution of 405 dpi. However, it is necessary to take a little look at the device's settings to get the most out of it. We thus advise you to access the settings, choose the display tab, open the screen profile selection and choose the Natural mode, the Vivid mode is not very convincing. Once this is done, you will get an average delta E of 2.3. This value means that the colorimetric drifts of the screen are globally so weak that they prove to be imperceptible for the human eye. If videographers calibrate their screen at 6,500 K to work, you will have here a screen at 7,010 K, close enough to the video standard to be satisfied with it. Oled obliges, the contrast of the slab tends towards infinity.


Afin to guarantee optimal comfort, the OnePlus 7T slab is capable of climbing up to 566 cd/m² and descending up to 2 cd/m². It therefore remains legible in full sunlight and does not damage the retina in complete darkness. It also offers a rather good reactivity, with a tactile delay of 72 ms. Finally, its only deficiency is on the reflectance side, much too high (53.2%).


La how to calibrate the 7T display.


In In terms of performance, the OnePlus 7T offers a paradoxical experience. Equipped with 8GB of RAM and a Snapdragon 855+ chip, one of the most powerful on the market today, the smartphone delivers excellent multitasking results (index 99.89) and is positioned on the second place on our podium, just behind... the OnePlus 7 Pro (100).

In however, things are getting worse on the gaming side. The OnePlus 7T has a mixed performance here (score 53.28). That's a little less than the 7T Pro (59.77), but more importantly, it's not as good as its direct competition. This translates into disappointing graphics and unframerate against a Xiaomi Mi 9T Pro, a Samsung Galaxy S10e or a P30 Pro.

This This shortcoming caused the overall performance index of this 7T to drop, and it finally stood at 76.58, slightly below its direct competition, whether on the lower or higher price brackets.


Il will visibly have two schools in 2019. On the one hand the Americans (Apple, Google), who opt for square photo islands on the back of their smartphones, and on the other hand the Chinese, who prefer the rounded shape. Unsurprisingly, OnePlus is in the second camp, accompanying Huawei. At the heart of its island, the 7T houses three modules: the main one, with a 48 MP sensor and a lens opening at f/1.6 (equivalent to 26 mm in 24x36), the second, dedicated to very wide-angle lenses, features a 16 MP sensor backed by a lens opening at f/2.2 (equivalent to 17 mm), and finally, the third and final module offers a 2x "telephoto lens" (8 MP, f/2.2, eq. 51 mm).


Les three sensors in their small round island.

Module main: 48 Mpx, f/1.6, eq. 26 mm

Avec the basic settings, the 7T captures shots in 12 Mpx, despite the definition of its sensor in 48 Mpx. The reason is, as always, the dupixel bining action, a technique that combines four pixels to catch more light at night. It is however possible to switch to 48 MP via the settings of the manufacturer's photo application.

Il must admit that the pictures are disappointing. During the day, the OnePlus 7T overexposes the scene strongly. The result is burnt whites and bland colors. To make matters worse, there is a loss of detail on the periphery. These results are all the more regrettable since the image processing performed by OnePlus 7T is rather light. The result is a controlled smoothing of the image, with all the details showing through, especially in the center.

By night, the result is strangely more convincing. The scene is better exposed and remains perfectly readable. Quite a few details are present. To obtain this result, OnePlus chose to extend the pause time (1/10 s) and to maintain the sensitivity (ISO 5000). Unfortunately, the colors are still inconspicuous.

By The night mode (available in the application designed by OnePlus) simply accentuates contrasts, even if it means delivering results that are more artistic than realistic.

Module very wide-angle: 16 Mpx, f/2.2, eq. 17 mm

By day, the very wide-angle module of the OnePlus 7T suffers from the same problems as the main module. The result is an overexposed scene and bland colors. In addition, the image processing is a little more present, erasing some image details. But overall, the result remains more than correct in the face of competition that is still groping around on its secondary modules, proof of this is the result of the Xiaomi MI 9T Pro.

Comme always on the very wide angle modules, things are much less shiny at night. The result here is drowned out by the image smoothing and only the center of the picture is correctly exposed. The entire periphery is therefore in the dark. The result is a photo that is not very usable.

Module 2x telephoto lens: 8 MP, f/2.2, eq. 51 mm

2x "telephoto" module of the 7T offers satisfactory shots. The scene is correctly exposed and the colors are faithful. A touch of smoothing is to be regretted, but nothing serious. We are dealing here with good quality shots.

Comme competitors, the 7T switches to its main module when the light runs out. Impossible to judge the quality of the third module at night therefore.

Mode portrait, macro, front sensor and vidéo

16MP front sensor offers a very satisfactory solution. The camera is not too abrupt in the strong lights and, in fact, exposes the scene correctly. The portrait mode is doing admirably well, the cropping is effective and the blur effect is quite well dosed - although we would have liked to be able to adjust it ourselves.

macro lens, although anecdotal, works well. Much better than on an Honor 20 Pro, but not yet at the level of what is offered on the Huawei P30 Pro.

Enfin, in video, you will be able to shoot up to 4K at 60 frames per second with an Electronic Image Stabilization (EIS) that effectively limits shaking.


OnePlus 7T comes with a 3,800 mAh battery. Not as durable as the OnePlus 7 and OnePlus 7 pro, it will still last 16 hrs 05 min before running out.


Par on the other hand, for the refill it is a real racing beast. It takes a hair more than an hour to get 100% of battery thanks to the fast charger at 30 W.
