Oppo Reno4 Professional 5G Arms-on Assessment: Technically Tempting

The Oppo Reno4 Pro 5G has just the right technical ingredients to create a smartphone that is desirable, exciting and, in some cases, appropriately different from the competition. I've been using it for a few days and enjoyed it too, but then I couldn't ignore the ingredient that hasn't been that good for long: the high price.

The midrange smartphone market is very competitive this year. We welcome devices that offer more value than ever before, but are still very price sensitive. The Oppo Reno4 Pro's £ 699 price tag of $ 898 means this otherwise good phone is tough to sell. Let's take a closer look at that.


Most noticeable is the size and weight of the Reno4 Pro 5G. It's only 7.6mm thick and weighs 176 grams, which feels like a feather in today's world. Phones regularly weigh more than 200 grams. It's sleek and slim, it slips easily into your pocket and pocket, and is extremely convenient to hold and use.

Sure, we've seen thin and light phones before, but that's noteworthy given that the Reno4 Pro 5G naturally has 5G and its antenna hardware, plus a 4,000 mAh battery and a built-in fingerprint sensor. It is an impressive technique to pack all of this into such a thin and light phone.

The test model shown here is in space black which has a subtle rainbow effect when it catches the light in the right way but is nowhere near as noticeable as the other design – the O and P logo branding. This unusual effect is located under the Gorilla Glass 5 (front and back) and is definitely an eye catcher. I like it, but the more I look, the more I see an uncomfortable mix of Chanel and Gucci branding, and that makes me less comfortable.

Don't worry – if you aren't there is also a galactic blue color that has a special diamond-like structure that apparently took six months to develop, and that benefits from increased scratch resistance and strong fingerprint resistance. This doesn't seem to apply to the Space Black version as the glossy finish is still going to be greasy.

If you ignore the colors and the use of the logo, this is where you can see just how slim and light a 5G phone can be. For a while, there have been concerns that any phone with 5G could be a boulder, but at least on Sub-6 5G devices, this has not proven to be right. The unfortunate thing for the Oppo Reno4 Pro 5G is that we already knew that very well, because it combines the 180-gram LG Velvet and the 184-gram OnePlus Nord.


The triple lens camera on the back has a 48 megapixel main lens, a second 12MP 120 degree wide angle lens, and a 13MP telephoto lens. The wide-angle lens is a purpose-built Sony IMX708 that offers 16: 9 video with special algorithms for video in low light. In addition to the rear cameras, the 32MP front camera also uses Oppo's Ultra Steady technology for smooth video performance.

If you take still photos for an hour, the phone performs well in bright and slightly cloudy conditions, although some may not like the high saturation levels but struggle with exposure when using 5x hybrid zoom. Portrait mode offers good edge detection and a natural look, while HDR works well with the selfie camera too.

A quick low-light test shows that the Reno4 Pro 5G does a great job of adding light and detail to still images taken in the dark without losing too much realism. While the noise is kept to a minimum, it smooths the image quite a bit. The new low-light video mode is less successful. It definitely brightens up the video but introduces a lot of noise and artifacts that affect the finished product. I'm using a pre-release version of the phone so there is a chance the software will be updated and the performance will be improved here.

Screen and performance

The Reno4 Pro 5G is small and light, but the screen is a sizable 6.5-inch AMOLED with a refresh rate of 90 Hz and a standard resolution of 2400 x 1080. By default, the screen automatically selects the best refresh rate for your activities to protect the battery life. If you don't trust it and always want the silky smooth scrolling of 90Hz screens, it may be forced to deliver at full rate anytime.

It's a pretty screen as you'd expect from the latest AMOLED technology, which has lots of color and some nice deep blacks. The Reno4 Pro 5G has stereo speakers – one at the bottom and a main dual-function speaker – and although the volume is very high, the super-slim body doesn't provide much bass response, resulting in an often harsh sound.

Qualcomm's Snapdragon 765G processor delivers the performance. With 12 GB of RAM and 256 GB of storage, Oppo hasn't held back in giving it room to breathe. At launch, the phone comes with Oppos ColorOS 7.2 version of Android 10 instead of the newly announced ColorOS 11, which is based on Android 11. Thankfully, ColorOS itself is solid and far better than it used to be, with a cleaner pixel-like look and reliable speed. The Reno4 Pro 5G will receive an update to ColorOS 11 next year.

ColorOS 7.2 has an interesting power saving feature that lets you choose six different apps that can run without limitation when the battery is low, including Google Maps and WhatsApp. These can be battery hogs, but Oppo promises 90 minutes of use with only 5% remaining battery.

The 4,000 mAh battery has lasted all day without any problems, but about 30% remains after use between 8 a.m. and 1 a.m. It doesn't last two days. Oppo's superb SuperVOOC 2.0 charging system is a very welcome addition as the battery goes from empty to full in just 36 minutes. This is an amazing feat. The 65 W charger required for this is also included, along with a transparent cover to protect the phone.

Price and availability

Oppo does not currently sell its smartphones in the US. The Reno4 Pro 5G will be released in Western Europe including the UK where it will cost £ 699, which is currently around $ 898.

The conclusion so far

Let's recap the right ingredients: The Oppo Reno4 Pro 5G is slim and light, has a large AMOLED screen, a strong processor and lots of RAM, as well as the fastest technology for charging batteries and a powerful camera with some useful additional features . All good stuff, except that Oppo is gone and put the price at the top of the scale and invited potential buyers to check out the £ 699 / $ 699 Samsung Galaxy S20 FE which has a faster processor, fabulous screen and great camera Has. Water resistance and also Samsung's good software.

If you pay less, you can get the absolutely beautiful LG Velvet for $ 599, even less for the Google Pixel 4a 5G for $ 499, and even less for the OnePlus Nord. All are pretty much the same in terms of specification and performance. Only the Oppo's SuperVOOC charging technology sets the Reno4 Pro 5G apart. But in such a price-sensitive segment, is this enough to spend more money than you technically need?

For the Reno4 Pro 5G to grab people's attention, it had to beat the budget Samsung Galaxy S20 FE and at least keep up with the rest of the competition. It's a very good smartphone, just like the Find X2 Pro, but like Oppo's capable flagship, the high price tag can put people into the arms of Samsung and others.
