OPPO A58 4G 2023 – all you need in a smartphone (review)

The OPPO A58 4G 2023 is all you need in a $299 4G phone – decent screen, adequate camera, and great battery life. But OPPO adds special touches like 33W fast charging and its AI camera smarts that add real value.

The OPPO A58 4G 2023 is an update to the A57 2022. And, we suspect one of the last 4G phones it will make. The price difference now between 4G and 5G System-on-a-Chip is negligible.

We must add that this is a cake-mix formula phone like so many of the A-series. It comes in 4G and 5G versions, with larger RAM and storage, different screens, camera sensors, batteries, processors, and even BBK brands realme and vivo, all baked into a cake that suits the various markets it is sold in.

That is a good thing, as OPPO makes the best use of its component purchasing power and factory setup to produce consistently well-made and popular phones.

We use Fail (below expectations), Passable (meets low expectations), Pass (meets expectations), Pass+ (near Exceed but not class-leading) and Exceed (surpasses expectations or is the class leader) against many of the items below.  You can click on most images for an enlargement.

Entry-level phones should at least score a pass mark against each category.

* Grey market – no Australian warranty

We strongly advise you to buy a genuine model with Australian firmware. It is easy to identify the Australian version – under Settings>About Device>Regulatory, there is an Australian RNZ C-Tick mark. There is also an RNZ C-Tick on the box. Read Don’t Buy a Grey Market Phone (guide)

Deep-dive

We perform over 70 tests, and the full specs are in a table at the end. The first part is an essential summary only.

First Impression – Pass

The Dazzling Green is just a little different and stands out. Of course, it is still a plastic and glass slab.

Screen: 1080p, 60Hz, LTPS/LCD – Pass

It is a nice, bright, reasonably colour-accurate screen. Its claim to fame is 680 nits brightness in sunlight (with automatic light exposure turned on).

Some will criticise 60Hz, but I would rather have this screen than a poor colour 120Hz one.

Processor – MediaTek Helio G85 – Pass

It is a reasonably powerful processor for the price.

It has 6GB RAM but can borrow up to another 6GB as slower virtual swap RAM from its storage. OPPO’s Dynamic Computing combines hardware and software to boost the system performance and manage multiple apps.

Storage is 128GB is eMMC 5.1 (90GB free). 

Performance is close to the Unisoc T610 or MT Helio G70.

Throttle – acceptable for this device

Comms – Pass

It has Wi-Fi AC 2.4/5GHz bands and keeps the speed well to 15m. In addition, it has NFC, GPS (single-band <3m accuracy), and USB-C 2.0 (480Mbps) for OTG cut and paste to an external flash/SSD.

Phone – Dual SIM and dedicated microSD – Pass

The strongest feature of this phone is the amazing signal strength – 15-20pW (picoWatts) that rivals the best-performing phones. But it only finds one tower (Qualcomm-based systems typically find the nearest four). It is perfect for the city and suburbs.

Battery – 5000mAH for two or more days of use – Pass+

It comes with a 33W SUPERVOOC Fast charger (inbox) and takes 1 hour and 19 minutes to charge. This is excellent for a low-cost phone. You can use any PD2.0 or 3.0 charger as it charges at 9V/3A/27W.

The SDR 1080p video loop is 14 hours and 32 minutes. You can expect two days of typical use.

Sound – Stereo – Passable

So few phones have great sound – OPPO Find N3 Fold – the most advanced foldable smartphone in 2023 at $2699 leads the pack there.

With the OPPO A58 4G, you get stereo sound (earpiece and a distinct bias to the bottom-firing speaker) with Ultra volume mode. OPPO claims it lifts volume 200% for the earpiece and 300% for the speaker. Great marketing, but the reality is that it maxes out at 85dB whereas most phones are 75-80dB.

It has no low-or-mid-bass, very slowly building high-bass and mids and then falls off a cliff at 6kHz to 20kHz. The sound signature is strictly mid for clear voice.

Build – Pass+

It is well-made and should withstand the knocks. Glass protection is not specified, but OPPO has a pre-installed plastic screen protector that helps. It does not come with a bumper cover.

It is rated IP54, which means rain rain-resistant.

Android 13, and you will get 15 – Pass+

OPPO has been steadily increasing its OS and patch support, and it comes with at least two OS upgrades and three years of quarterly security patch updates. Add the two-year warranty, and it’s a keeper.

OPPO A58 4G 2023 rear camera – Pass

First, remember the cake-mix analogy at the beginning. This phone supports over ten different sensors from Omnivision, Samsung, Sony, and GalaxyCore, so we will assume they are all from Omnivision.

It has a single 50MP (bins to 12.5MP) camera and a 2MP depth sensor for bokeh. As such, it is a simple point-and-shoot camera backed by OPPO’s camera smarts. For example, Night mode takes several seconds from shutter to finish, and focus can be a little slow.

Camera Comments

You can tell that the AI is working overtime here, and it is largely successful in binned shots to bring out details and colours. It is one of the better <$300 camera results we have seen.

• 1X Day Primary sensor: good dynamic range, bright colours and good HDR details in the shadows and highlights. Good detail in the foreground and background.
• 2X Day Primary sensor: Equally good as 1X
• 5X Day Primary sensor: Pushing the limits of digital zoom but has good foreground details and negligible background noise.
• Ultra-wide: N/A
• Macro: N/A, but 50MP sensor focuses down to 4cm
• Indoor office light:
• Bokeh Depth: Using AI, and without a human subject, it does not know how to separate foreground and background, so it is all bokeh.
• Dark <40 lumens: Quite a decent image but lacking details.
• Night Mode: Excellent colour, detail and range. It picks up details from the monitor screen.
• Selfie: The 8MP is adequate.

Video (we are not video experts):

• Primary sensor: You can shoot at 1080p@30fps, and the day/office light results are good, but low light is lacking.
• Selfie: 1080p@30fps; results are adequate. Fine for video conference.
• Overall, the video is good but lacks dynamic range in low light.

CyberShack’s view – OPPO A58 4G 2023 is a well-featured 4G phone

It is hard to be enthusiastic about a $299 phone, no matter how nice the Dazzling Green is.

It is a good 4G phone (signal; strength is superb) and has a suitable point-and-shoot camera, battery life (fast charge), decent 2+2+3 warranty, OS and patch policy. Add OPPO quality, and it’s a good buy.

Competition

• Motorola G54  5G 128GB $299 Motorola G54 – Under $300 for a 5G smartphone
• OPPO A78 4G 5G Qualcomm SD680 $329 (the one to buy for the strongest phone signal).

Ratings

• Features: 9 – everything you need
• Value: 8 – reasonable price, but the OPPO A78 4G at $329 is far better value and performance.
• Performance: 8 – MediaTek SoC and modem are average performers. Only finds one tower in 4G tests.
• Ease of Use: 9 OPPO ColorOS 13.1 and 2+2+3 (warranty/OS/patches) is great
• Design: 8 – Another formula PMMA glass slab

Pro

Adequate performance – not for gamers

Bright, colour-accurate 1080p 60Hz screen

Excellent battery life and 33W charger

Excellent quality build and 2+2+3 policy with local support

Average camera – better than social media class

Con

Despite signal strength, it is a city and suburbs phone only

AI image post-processing is limited

Single mic means not as suitable for hands-free use
