OPPO Reno4 5G – everything you expect from a mid-range 5G

OPPO is now #1

The OPPO Reno4 5G is part of the Reno mid-range value line that comes with stacks of goodies for the reasonable price of $799.

Reno is an OPPO sub-brand. It’s positioning is just below the flagship Find X-series and above the A-series. Its mission is to offer greater value even if it competes with other OPPO models.

For example, the OPPO Reno4 5G faces off to the Find X2 Neo at $899 and the Find X2 Lite at $649. The other Reno4 Z 5G marks new ground sitting above the A91 and Below the Find X2 Lite 5G.

The OPPO Reno4 5G uses the Qualcomm SD765G. It is a companion to the OPPO Reno4 Z 5G that sells for $599 and uses the new MediaTek Dimensity SoC – a review will be coming soon.

Australian’s love the Reno series. In 2019 Reno was responsible for its largest single smartphone sales segment.

So the OPPO Reno4 5G has a lot to live up to. Let’s see, shall we?

(Spoiler – OPPO you have done it again with a 6.4″ AMOLED screen, 65W SuperVOOC 2.0 charging and a great camera).

First impression – EXCEED

Its not just the grippy Galactic (Ice) Blue back with a tri-camera. It is also the aluminium anodised matching frame and superb build quality that makes this an OPPO Reno.

The front screen is vibrant and colourful with a distinctive dual-camera selfie ‘pill’ slot on the top left. But the thing that impresses me most is the galactic speed 65W charging that fills it 0-100% in well under an hour.

Screen – EXCEED

ProtectionGorilla Glass 6 and pre-fitted screen protector
Face ID
Optical under glass – Test: 9/10
Test 8/10

This is a bright and vibrant screen with accurate levels of DCI-P3 and sRGB – more than you could reasonably expect. Colour accuracy is good enough for Creatives and VLoggers.

Our tests confirmed OPPOs conservative brightness figures. It is little unfair to quote 800 nits peak because HBM (high brightness mode) only cuts in a very small portion of the screen when playing HDR content.

Processor – PASS+

GPUAdreno 620 Compute Open CL: 1254
Game useThe G stands for gaming functions like a game ‘smoother’; and a fast loader. Add that to OPPOs game boost and an Adreno 620 GPU, and it can handle most games with good frame rates.

Terrific thermal management as we have come to expect from OPPO designs

Not only is this our favourite Goldilocks processor (just right) OPPO’s thermal design skills show again. It does not throttle at all.

OPPO has implemented USB-C 3.1 Gen 1 which in theory is 5Gbps/635MBps half-duplex. So we expect a suitable external SSD to achieve around 250-300MBps sequential read. Regrettably, data transfer is still at USB 2.0 speeds, so it is not for videographers. At this time, apart from Samsung S20/Note20, few phones support USB-C 3.1 Gen 1 speeds.

OPPO Reno4 5G

OPPO earns the PASS+ mark here due to the thermal management. Shame about USB-C 3.1 though.

That is one fast charge curve – straight up in under an hour

It is good for a day’s typical use and perhaps two with lighter use. But it EXCEEDs due to the incredibly fast 65W Super VOOC 2.0 charger.

Sound – PASS

Earpiece – no setting
Handsfree – adequate volume and mic sensitivity

* It is not fair to measure the sound signature on a mono speaker system. The primary use is for clear voice. It is not for music or movies with no bass or mid before 1000Hz and no treble after 10kHz.

BT headphones – EXCEED

The BT 5.0 drove our reference Sony WH-1000xM4 in SBC, AAC, aptX and LDAC modes and provided good clear sound and plenty of volume. Few devices have such a wide selection of BT Codecs. Dolby Atmos presets for smart, movie, gaming and music do alter the sound stage in the headphones.

Sound quality

We do not measure the frequency response as it is a mono speaker. Suffice to say it focuses on clear voice.

Build – PASS

Size/Weight159.3 x 74 x 7.8mm x 183g
ColoursGalactic Blue and Space Black (the effect is the ‘Reno Glow that is fingerprint-resistant)
BuildGlass: Gorilla Glass 6
Frame: Not determined – it looks like colour matched anodised aluminium
Back: Plastic with a metalised painted Reno Glow finish
IPNot rated but splash proof
In the box65W charger
USB-A to USB-C Super VOOC 2.0 cable
3.5mm standard buds
TPU bumper cover

OPPO build quality and finish is superb, and it has a two-year warranty and excellent local service. To earn extra points here, it would have required an IP rating.

Android 10 – PASS+

AndroidGoogle Android 10
UIColorOS 7.2 and new AI app preload
GoogleAll standard apps, Google Lens and Assistant. Dedicated Google Assistant key.
BloatwareMostly Google alternatives and utilities
Update PolicyIt will get Android 11.

SecurityFingerprint –  under glass Goodix optical 9/10 tests

I like ColorOS and its direction. It is like the oil on the wheels that makes Pure Android more usable.

Missing – PASS

IP RatingNot a deal-breaker – you need to spend at least $100 more
3.5mmDitto – and it has a USB-C DAC inbuilt.
Micro-SDDitto and it can handle OTG devices to 1TB
QiSpend another $100 more

If these are important the LG Velvet for $899 has it all.

Camera – PASS+

OPPO Reno4 5G

OPPO has some of the best camera tech with periscope zoom, gimbal lens mounts, AI etc.

This gets AI but otherwise is a fairly standard rear tri-camera setup. The dual selfie is interesting. Overall its is a great performer, but you can buy better cameraphones from its BBK siblings.

8MP U;trawide lens accounts for colour differences

Indoors Office Light (400 lumens)

Great dynamic range, accurate colours and fine detail – you can shoot 48MP if you wish.

Low light (room <40 lumen)

This is acceptable for a dark shot but the night mode below is far brighter
Night mode brings up brightness and details but the colours are off – still an excellent shot


It does not have a dedicated macro lens and there are no settings for same. This is no issue unless you plan to use macro.

You will note that the 48MP cannot focus below about 5cm (flower and greenery) but if we back off to 10cm it can pick up details (look at the flower leaves and greenery lower down).


We don’t publish selfies because of their increasing use for ID Theft. And its not because my face may break the lens.

This has a 32MP binned to 8MP and a 2MP depth sensor. The 2MP adds detail and helps separate the foreground from the background.


We wanted to comment on Night mode as OPPO makes such a big thing of it. It is computational photography (just like Google Pixel) that takes a bracket of shots and bins them taking the best pixels from the bracket. It then post processes the shot according to its AI to give you what it thinks the shot should be.

But all that post-processing can add noise and alter colours. OPPO does a pretty good job brightening but the end result is not as as good as I have seen.


4K@30fps with Gyro-EIS is very good – pans are smooth and even. Colours are excellent, and it is quite competent at low light video without too much post-processing noise.

Sound is stereo recorded, but there is no beamforming, so if you are trying to capture sound, then a USB-C mic is best.

GadgetGuy’s take – OPPO Reno4 5G is one of the better ‘daily drives’

The OPPO Reno4 5G is the best SD765G implementation out there at the $799 price. It competes squarely with the Google Pixel 4a 5G, and offers just a little more. Mind you the Pixel 4a is a formidable device too – you can’t go wrong either way.

But due to a recent price drop, the OPPO Find X2 Lite at $649 is the superb deal now.

And for those that want the best SD765G then at $899, you can get the OPPO Find X2 Neo 5G or the LG Velvet 5G with Qi charge, microSD and IP68/MIL-SPEC.

Rating explanation

As you know a PASS on all tests earn 4/5. Then we add points for EXCEED and deduct points for FAIL.

Do we rate it in its narrow $100 price bracket or overall in the $700-999 bracket?
Answer: It ranks highly on hardware specs but not as high as others on value.

Grey market – no Australian warranty

We issue the standard warning that you must buy the genuine model with Australian firmware as it works on all Australian Telco carrier 4 and 5G bands and can make a 000-emergency call (not 911) without a SIM. As it is 5G capable the IMEI is initially locked to Australian Telcos – international models will not work here. Do not buy models PDP00 or PDPT00.

We have named and shamed the major grey marketers here. If you are going to spend this much money, get a genuine ‘Made for Australia’ model.
