OPPO A91: the advantage of a thin body and a good camera


The OPPO A91 smartphone belongs to the middle class. This can be determined immediately by its design. The device received an AMOLED screen, a powerful processor and a decent camera. The device has a number of other advantages, which we will discuss below.

Bright screen with good color rendering

OPPO A91 has a 6.4-inch AMOLED matrix with a resolution of 2400x1080 pixels.


The pixels here have received a high density: 408 ppi, which allows you to have a clear picture even when viewing content at a short distance.

In the center of the panel there is a teardrop-shaped cutout for the front camera. It looks organic and unobtrusive.

The device is equipped with the sixth reincarnation ColorOS shell, which does not have a dark theme. However, ColorOS 7.1 update is expected soon, where it will appear. In the meantime, you can walk around with a light interface.

Besides, the model screen has no obvious flaws. It is equipped with a flicker reduction function (DC Dimming), you can enable night mode on a schedule and change the color balance.

The device received a fingerprint scanner, which is built into the display. His work is accompanied by interesting animation, the unlocking platform is in a convenient place. There is no need to reach for her. True, sometimes the scanner takes a little longer to recognize.

Four effective main camera sensors

The manufacturer has equipped the device with a main 48-megapixel lens. He is assisted in his work by three additional sensors: a wide-angle with a resolution of 8 megapixels, a depth sensor and a macro lens.


OPPO A91's photo capabilities are above average. His shots are rich and detailed. Saturation is added by the Vivid Colors mode, which can be activated at any time. The main camera of the smartphone is distinguished by fast autofocus, good shading, and a well-functioning night mode.

The overall impression is slightly blurred by not very high performance of auxiliary lenses. This is almost the norm for the middle class. For example, an ultra wide angle lens sometimes suffers from a lack of sharpness.

OPPO A91 records video in full Full HD resolution at 30 frames per second. This is not the highest resolution, but it has electronic image stabilization for better image quality.

Slim and practical body

OPPO A91 received a case, the thickness of which does not exceed 8 mm. This is if you do not take into account the protruding parts of the camera block. The back cover, shimmering in the rays of the sun, pleasantly surprises with its colors.

At the same time, the device was not left without all the essentials. There is an audio jack, legible stereo speakers with a good headroom.

It is worth noting a separate tray for two SIM and memory card. Fans of a contactless payment method will appreciate the presence of an NFC block. It will be useful in any store and when replenishing the balance of travel cards.


The Helio P70 chipset is very fast. The presence of 8 GB of RAM contributes to high performance. This eliminates the appearance of lags, slowdowns and freezes of the interface. All programs work properly, animations run smoothly, switching between applications is fast.

The games are quite dynamic and convincing. Especially on medium graphics settings. At maximum speed, most of them also work well. Fans of increased requirements can use the enhanced performance mode. Only then will the autonomy be reduced.


The device was tested in synthetic benchmarks. In AnTuTu, he scored 183,260 points, which looks decent.

Sufficient autonomy

The device is equipped with a 4025 mAh battery. This is a low figure according to modern concepts, but the situation is improved by the presence of an AMOLED matrix and advanced energy saving. When using the device for communication, the Internet and listening to music, one charge is enough for a day. For game lovers, this time will be reduced by several hours.

In loop playback mode, the battery can last thirteen hours. This is at an average screen brightness.

OPPO A91 supports proprietary VOOC 3.0 fast charging technology. It takes about an hour to fully restore the battery's energy reserves. In just 20 minutes, a completely dead battery can be charged up to 30%. The standard adapter allows you to do this.


Many people will like this performance. You can connect your smartphone to the charger during your lunch break and the resulting charge will be enough to work until the evening. Especially if you do not use games that are in your smartphone.


OPPO A91 is generally a decent device. It has a striking appearance, a thin body, an NFC unit and fast charging. But there are also disadvantages: the video recording quality is low, and the sub-screen fingerprint scanner works with flaws.

The device will certainly be in demand among those who love an interesting design and nice little things, but are not picky about the quality of photos and videos. Individual shortcomings of such users do not care.
