Test Oppo A9 2020: the best competitor of the Xiaomi Redmi Note 8 Pro

Presentation

Oppo A9 2020 bets on criteria that often hit the smartphone market. A large screen, a big battery and a photo part articulated around a 48 megapixel sensor. It is launched at €259, a price tag that many competitors are offering. Among them, we can cite the very goodXiaomi Redmi Note 8 Pro, but also the popular Samsung Galaxy A50, which is a little more expensive.

Ergonomics and design

Oppo A9 2020 does not have unusual physical characteristics. This doesn't prevent it from being well finished overall, with a back with rounded edges that is as pleasant to look at as it is to hold. Of course, with a 6.5-inch (16.51 cm) diagonal screen, the A9 is not easy to handle with one hand. The screen occupies just under 83% of the front of the smartphone, which puts it slightly behind the Redmi Note 8 Pro. Oppo's cell phone retains a fairly wide lower edge and a small notch in which the front photo module is housed.

For the smartphone lock, Oppo has chosen to offer several possibilities. On the back, the A9 2020 carries a fingerprint reader. It works without any problem, the reader is fast to unlock the mobile. As often, this positioning prevents access if the smartphone is placed on a table. To this, the A9 adds facial recognition, based solely on the frontal photo module.

Oppo A9 is capable of accommodating 2 nano-SIM cards and a microSD card at the same time. Quite practical so that you don't have to choose between a second mobile package and the extension of the internal memory. The A9 2020 is also equipped with a USB-C port and a 3.5mm mini-jack. Like almost all smartphones in its range, however, the Oppo terminal has no waterproof certification.

Audio

La 3.5 mm mini-jack plug still makes a strong impression on entry-level and mid-range smartphones. Good for lovers of headsets and other wired devices. The Oppo A9's resistance is pretty good overall. It's only its power that may penalize users of very greedy headsets. The rest of our measurements place the Chinese mobile in the average range, with controlled distortion, a fairly wide dynamic range and good stereo image reproduction.

Côté loudspeakers, the A9 clearly stands out from the competition. While most smartphones in its range are satisfied with a single speaker, often medium, the Oppo A9 has 2 stereo speakers. This is enough to deliver a fully usable sound, both for video and music, to a lesser extent.

Screen

Pas of miracle for the screen of the A9 2020, the Oled has not yet made a breakthrough - except at Samsung - in this price range. The A9 features a 6.5-inch IPS panel in 1600 x 720 pixel resolution. This HD+ definition puts it below the Full HD+ screen of a Redmi Note 8 Pro. The 269 dpi resolution of the Oppo will be penalizing in certain uses only, those that require great finesse. The readability of the A9's screen is satisfactory overall. It benefits from a maximum luminosity of 485 cd/m² and a light reflection rate of 45.8% allowing it to remain readable in full sun without too much trouble. The minimum brightness of 3.4 cd/m², while not excellent, ensures that it is not too bright at night. We also measure a contrast ratio of 1,383:1, honest for IPS.

Côté colorimetry, the Oppo A9 2020 shows itself in a good light. We measure a delta E at 2.5, attesting to faithful colors. The color temperature is close to perfection with a measurement at 6,437 K, close to the video standard (6,500 K).

Enfin, the reactivity of the screen is in the average of our comparison. We measured a tactile delay of 97 ms and a remanence time of 16 ms.

Performances

Oppo A9 2020 lands with a Qualcomm Snapdragon 665 SoC on board. Featuring 8 Kryo 260 cores (4 x ARM Cortex-A73 at 2 GHz and 4 x Cortex-A53 at 1.8 GHz), backed by 4GB of RAM, it delivers solid performance. In our SmartViser test, which simulates multitasking, the A9 scores 88.96, close to that of theRedmi Note 8 Pro. In practice, this score translates into great fluidity in use.

For the video game, it's the Adreno 610 chip that takes over. This chip enables the A9 2020 to offer great fluidity in mobile games. In this exercise, in our SmartViser test, Oppo's smartphone scored 76.47, just behind the Redmi Note 8 Pro once again.

Photo

Oppo A9 2020 can count on four photo modules. The main one relies on a 48 megapixel sensor and an equivalent 27 mm optics opening at f/1.8. The second is based on an 8-megapixel sensor and ultra-wide-angle optics. The other two modules, with 2-megapixel sensors, are only used in Portrait mode. Here again, we can say that the A9 rubs directly against theXiaomi Redmi Note 8 Pro which offers something quite similar.

Module main: 48 Mpx, f/1.8, eq. 27 mm

We devoted a complete article to the performance of the main module of the Oppo A9. You can refer to it for more details on its good performances, especially in low light conditions.

Labo - The Oppo A9 2020 better than a Redmi Note 8 Pro in photo

We got their hands on the new Oppo A9 2020. It started its tour of our laboratories and we were very pleasantly surprised by...

Module ultra-wide-angle: 8 Mpx, f/2.25, eq 16 mm

ultra-wide-angle module has become a must for today's smartphones. It allows you to capture a wider field, useful for landscapes, buildings or to give a small effect to your shots. Here, the module is based on an 8MP sensor and 16mm equivalent optics, exactly what the Redmi Note 8 Pro offers. In daylight, the A9 does a little better than its competitor by offering a little more detail. The colors are also better preserved at Oppo. It is still far from the best in the discipline.

In low luminosity, the smoothing comes to degrade very clearly the clichés. The elimination of electronic noise seems to pose big problems for the A9 2020. He can console himself by saying that the Redmi Note 8 Pro doesn't do much better.

Module front, video and fashion portrait

portrait mode of the Oppo A9 2020 is not the best we've come across. The cut of the subject is not very precise and sometimes forget some areas of the image.

À In the front, the 16 megapixel sensor provides quite successful self-portraits. The details are there and the backlighting is very well mastered. On the other hand, we are more circumspect about the default treatment, which smoothes everything in its path, at the risk of making the subject look like a wax doll.

For video capture, the Oppo A9 can shoot in 4K at 30 fps, but it will be better to be satisfied with a Full HD definition. Indeed, the rendering is more prone to jerks in 4K. Exposure transitions are properly managed and the focus tracking provides an honorable job.

Autonomy

Avec its 5000 mAh battery, the Oppo A9 is going to take our autonomy test by storm with serious assets. Indeed, it obtains an excellent score on our SmartViser test, on which it held for 21 h 15 min. In practice, this allows it to withstand more than two full days of standard use. More intensive use will rarely see the A9 2020 expire before a good day and a half.

Avec its charger provided in the box, the Oppo A9 requires a little more than 2 hours for a full recharge.
