OnePlus 7 Test: a reference in the mid-range market

Published on

A worthy successor to the 6T, the OnePlus 7 comes to us after its soberly titled “Pro” version, which was released on May 21. Determined to shade the older ones and a competition that is already looking tough with the Huawei P30 released a little over 3 months ago.

Our OnePlus 7 Pro test is already online

Like its Pro version, the OnePlus7 is delivered in a very nice white case stamped with the brand logo. You will find there:

  • The smartphone, here a model with 8GB of RAM and 256GB of storage in its only available color “Mirror Gray”.
  • A flexible and transparent protective shell.
  • A USB-C power cable.
  • An adapter plug / USB cable.
  • A protective film already affixed to the screen.
  • Documentation and an extraction tip for SIM card.

A sober design, but not very practical for one hand

The first thing you notice about the OnePlus7 compared to its predecessor is its design. Although the smartphone is a little smaller than its “Pro” counterpart, it keeps the same materials on the back, namely a glass back with very pretty reflections, but which keeps fingerprints and slides easily in hand. The use of a shell (the one provided for example) is therefore strongly recommended.

Unlike the “Pro” version, there are not 3, but only 2 photo lenses, the flash module. The brand logo obviously remains present, but in a very sober way.

At the front, a 6.41-inch AMOLED screen with sharp edges and a small notch for the front camera. If the latter is not really binding, note that you will necessarily lose the screen size available for your applications.

We are therefore far from the OnePlus7 Pro with its curved 6.67 inch screen and no notches, but the result remains largely satisfactory to fully appreciate your video content or for readability during games. The only problem is that the protection provided and integrated into our device easily retains dust.

Non-Pro version obliges, the OnePlus 7 only proposes a Full HD+ definition with a rate of 60Hz (against the 90 on the “Pro” version). If the result is necessarily more subdued, it remains relatively good quality: the colours are very well represented and the brightness remains very good for daily use.

The fingerprint reader at the bottom of the screen is still present, but has gained significantly in efficiency since its version on the OnePlus 6T. The unlocking is almost automatic and we did not encounter any problems or latency during our test week.

Facial recognition also does a remarkable job, even when the phone is placed on a desk and our face is not exactly in front of the device.

A small negative point in terms of ergonomics, you will quickly forget the idea of using OnePlus 7 with one hand. If the buttons respond well to finger pressure, the fingers are placed too far from the home button and fingerprint reader, which will very often require you to reposition your fingers or grab the smartphone with both hands. Note that the OnePlus 7 is a little smaller than its Pro counterpart, but also lighter in hand with its 182g weight.

Finally, there is the absence of a Jack plug, which will definitely disappear, to make way for wireless headsets and headphones. For those who do not own wireless devices, you will need to use a USB-C connection or a Jack/USB-C adapter.

Excellent performance for a correct autonomy

The OnePlus 7 is equipped with Qualcomm’s latest processor, the Snapdragon 855 chip, making it one of the most powerful smartphones in its price range. Applications run without any problems or slowdowns and we switch from one application to another smoothly, even if several games are opened at the same time. Add to that the 6 or 8 GB of built-in RAM and you have a real power monster that will easily run your most demanding games and applications.

During large and intense gaming sessions, however, the smartphone tends to heat up a little (with no impact on performance, but we can ask ourselves the question about battery life over a long period of time). Fortunately, OnePlus 7 can lower its temperature quite quickly.

Speaking of video games, OnePlus includes a basic mode called “Fnatic” that will launch automatically when you trigger a game application. This application not only optimizes your GPU for your games, but also blocks notifications from other applications so you don’t have to worry. A nice addition on paper, but one that you will quickly have to deactivate in order not to miss an important SMS from your boss in the middle of a Pokémon GO or PUBG game.

The OnePlus 7 carries a 3700 mAh battery and easily holds a full day of daily use (including Spotify, Netflix, YouTube and Pokémon GO). Count a little less if you want to use it on a sustained basis, especially for video or audio content in streaming. However, the smartphone supports fast charging. During our tests, its battery was fully charged in just over an hour. However, you will need to bring the cable and adapter provided since the phone is not compatible with wireless charging.

Real audio improvements

As mentioned earlier in this test, it has been a while since OnePlus decided to abandon the Jack plug. While this decision may cause some disappointment, it is nonetheless logical given the evolution of current technologies. For latecomers, it is always possible to use an adapter, but it will then be impossible for you to recharge your smartphone at the same time.

When the 6T came out, many were surprised to see the disappearance of the Jack plug, simply replaced by a simple aesthetic grid, emitting no additional sound. For the OnePlus 7, the company has played the improvement card and finally offers two real audio outputs for a sound that is more than correct, despite slight saturations in the highest levels.

Excellent photo performance… By day

As mentioned earlier, OnePlus 7 has only two photo sensors on the back. These two modules are 48MP (f/1.7) and 5MP (f/2.4) respectively.

Outdoors and with good light, the device does its job very well: the colours and contrasts are bright and true to reality. Small details such as hair are also well highlighted. However, it is regrettable that the camera’s activation time is a long hair and that the zoom (up to 10x) transforms the scenes into a real porridge of pixels.

The “photo” mode is very refined and has four main modes: video, photo, portrait and night landscape. You will therefore have to go through the phone a little bit to find the different options and in particular the professional mode that will allow you to replace the A.I. (already very correct) of the device. The latter will also allow you to make videos in 4K to 60FPS for a rather impressive rendering.

The portrait mode also does quite well by reproducing a convincing Bokeh effect and taking into account the limits of the face and hair, even with several people in the frame. The software processing is just as efficient and perfectly manages the movements of faces, but also of the surrounding light.

The front camera has 16MP (f/2.0) and provides very good quality for your selfies. The latter has an “I.A.” mode disabled by default and supposed to improve the quality of your shots (the results being however too little visible to make it a real argument). The portrait mode of the front camera also manages the contours rather well to blur the environment, but still remains in below of its rear counterpart.

It is in low light and at night that things go wrong. The software processing has some difficulties to manage colors and contrasts, offering a scene that is not very similar to reality or even completely yellowed. The “night landscape” mode will therefore be used to recreate your scene as best as possible (but without fully achieving it if your subject is in darkness).

Communication and conclusion

OnePlus 7 is fully compatible with the 4G network of French lines and we have had absolutely no problems with it. The smartphone obviously has a Bluetooth 5.0, but also an NFC chip whose technology is increasingly used here. However, it will not benefit from a version compatible with the future 5G as will be the case for its Pro version.

OnePlus has done an excellent job with its latest mid-range product. OnePlus 7 takes over many aspects of the 6T by improving many of its small flaws. A sure bet, therefore, for those who want an efficient smartphone capable of taking beautiful shots. However, we regret the difficulty of software processing for low-light photos and the battery which, like the Pro version, sometimes has difficulty lasting a full day depending on how much you use it.
