OPPO has a wide variety of devices available in the market nowadays. The new A series of smartphones from OPPO is curated for the mid-range market. With the mid-range market being so saturated with smartphones nowadays, how does the new OPPO A91 stand out from the rest?

Let’s just say that for the price of RM999, the OPPO A91 is not the cheapest smartphone in the mid-range segment. So what’s so unique about this phone?

The entire OPPO A91 box itself is fairly simple. We have the image of the phone itself and there’s also a RAM + storage configuration printed at the top right corner. Makes things easier for those who want to know the information at a glance.


Digging out everything, we have:

  • OPPO A91
  • 20W Charger
  • A pair of earphones
  • Documentation
  • Clear TPU case
  • USB-C charging cable

And that’s about it. Pretty straightforward, in my opinion.



Looking back at the box itself, the OPPO A91 should be available in the glistening color as well… but that’s not the case. For us here in Malaysia, we only have the Lightening Black color. Despite being named as “black”, it’s still a very shimmery color.


However, OPPO used a high gloss finish on the OPPO A91 – which means that it is very prone to scratches. Make sure to use that included TPU case. Luckily OPPO included a transparent case so that the shimmery Lightening Black can still be seen.


OPPO also made the A91 to be really thin – which is something that I think is worth mentioning.

Connectivity & Ports

Once again, nothing particularly wrong with the phone itself. It supports 5GHz WiFi and it uses USB-C for charging too.


It also comes with an audio jack and a total of 3 independent card slots too. There’s no eSIM support here so having triple card slots is definitely needed.



OPPO opted for a decently-sized 6.4-inch AMOLED display with 2400×1080 pixels in resolution. The entire display looks and feels amazing and the colors are well-balanced. Of course, with an AMOLED screen means that OPPO is using an under-display fingerprint scanner too. Not something that I personally prefer, though.


There is a waterdrop notch at the top for its selfie camera and we’ve become accustomed to that for more than a year now.


The cameras on the OPPO A91 are pretty basic for cameras of today’s mid-range smartphones. There are a total of 4 different cameras at the back of the phone – but only 2 of them are usable.

  • Quadruple rear-facing cameras
    • Main: 48MP (only 12MP is usable) f/1.8; PDAF
    • Ultra-wide angle: 8MP f/2.2
    • B/W sensor
    • Depth sensor
  • 16MP f/2.0 selfie camera


Look at the specs itself, it’s quite weird that OPPO included a total of two sensors. That means if you’re not keen on using those two extra sensors for bokeh shows or whatnot, then they’re essentially there just for show.

Even the 48MP camera can only shoot 12MP pictures. There is no way to enable 48MP mode, so it’s defaulted to the pixel-binning mode by combining 4 pixels into 1.

Still, the picture quality turns out to be rather okay, as shown in our video at the top of this review. To view all the pictures taken with the OPPO A91, please watch the video at the top of this review.

Software – Android 9.0 Pie with ColorOS 6.1.2

We’ve used ColorOS 6 on many other smartphones in the past. It’s quite a good custom Android skin as it does its job nicely. There is some clunkiness here and there and there’s no dark mode, but it does its job well overall.

Performance & Gaming

The OPPO A91 is using a rather dated chipset. It is packed with:

  • 6.4-inch AMOLED display
    • 2400×1080 pixels in resolution
    • Waterdrop notch
  • MediaTek Helio P70 chipset
  • 8GB RAM
  • 128GB of internal storage
  • 4,025mAh battery

Its overall performance… is rather disappointing since the chipset is rather old at this point in time. That MediaTek Helio P70 chipset is more than a year old now, and its performance is the same as the OPPO F11 Pro from a year ago.

Battery & Charger

Its battery life though… isn’t particularly bad. It can barely last throughout a day’s use, but we’ll have to be thrifty. It can achieve nearly 10 hours in our test so maybe we’ll have to lower the brightness to hit that 11-hour mark in our test.

With that 20W charger, the OPPO A91 can charge from 15% to 100% battery in just about 63 minutes. That’s quite good.

Wrapping up the OPPO A91 review

When we focus at only the phone itself, there is nothing wrong with the phone itself. The chipset might be a little dated, but it still works great. The camera is decent and the battery life is pretty okay.

When we take the price into consideration, that RM999 price tag makes it difficult for us to recommend it.

I think that if you can find the OPPO A91 during a flash sale or promotion, then it should be better. RM999 is just a tad bit high, in my opinion.
