TechRadar Verdict
The Oppo Reno12 FS 5G is a very cheap phone that does everything you need a typical smartphone to do. Rather than aiming to be consistently average, it splits its focus by chasing high performance. The display, value, and especially the battery are all well beyond expectation, whereas the performance, durability, and camera all have plenty of room to improve. Oppo has been keen to market the Reno 12 FS as a do-it-all AI cameraphone, but in reality the specifics of how you plan to use it will determine whether this one makes sense.

Oppo Reno 12 FS 5G: Two-minute review
The Oppo Reno 12 FS 5G is a budget phone done the Oppo way – better-than-average specs, a great sense of style, and cost-cutting decisions that mostly land on the side of confusion rather than frustration. This is a phone that, despite its shortcomings, punches well above its weight, most obviously with its great 6.67-inch display. Though far from perfect, this is a capable budget handset that handles 90% of what we use our phones for every day without complaint.
At a fixed price point of £299, the biggest selling point the Reno 12 FS has is its excellent value for money. There are few other models on the market that offer this much utility for so little money, and a combination of 12GB of RAM and 512GB of storage is almost unheard of in this price bracket.
The Reno 12 FS continues to impress with its software experience – that is, once you get clear of the awful bloatware the phone ships with. ColorOS 14 is otherwise a swift and snappy experience, with terrific customization, though slowdown can hold the phone back at seemingly random times. It’s clear that the included MediaTek Dimensity 6300 chipset can’t quite keep up with modern demands.
As for cameras, the Reno 12 FS struggles to keep pace with close competitors like the Samsung Galaxy A35, or even the iPhone SE. The main 50MP camera can be coaxed into producing photos that are acceptable, so long as conditions are ideal, but don’t bother with the 8MP ultrawide and 2MP macro camera. It would have been wiser for Oppo to have spent those resources on a better single-camera system.
Overall, the Reno 12 FS 5G will work for a specific type of user, and should appeal far more to media consumers than media producers. If you’re looking for a device to keep you connected, browse the internet, and watch videos, this is a solid choice – but those looking for photography power or totally impressive performance should look elsewhere.
Oppo Reno 12 FS 5G review: Price and availability
- Costs £299, available in one configuration
- Sole model comes with 512GB of storage
- Not available in the US or Australia
The Oppo Reno 12 FS 5G marked Oppo’s re-entry to the UK market, and now forms a core part of the brand’s steadily growing phone lineup. It comes in a single model, with 12GB of RAM and a huge 512GB of storage for £299. It’s not available in Australia, where it’s missing from an otherwise fairly robust range of phones, including the base-model Reno 12 for AU$799 (about £400). Oppo doesn’t sell its phones in the US, though sister company OnePlus sells very similar models.
Half a terabyte of storage and as much RAM as a Galaxy S24 for under £300 is no small feat, and while the Reno 12 FS doesn’t exactly sport a flagship chipset, it generally packs enough power for day to day use and even some gaming. That’s pretty phenomenal value for money already. Those who want a capable all-rounder for light use and the occasional session of Call of Duty Mobile won’t be disappointed.
At the time of writing, the Reno 12 FS 5G sits towards the lower end of the Oppo smartphone lineup – I mention this because the Oppo phones for sale in the UK have changed continually over the last few months as the company establishes its presence once more. It walks the line between budget and mid-range tiers and aims for the best of both – with a great display and fresh design, but a lacking camera system and cheap-feeling construction. It would have benefitted from a simpler, more focused allocation of resources.

Oppo Reno 12 FS 5G review: Design
- Simple but solid silhouette
- Breathing Light LED is a fun addition
- Cheap materials that mark easily
For such a simple phone, I do quite like the design of the Oppo Reno 12 FS 5G. This is a wide, thin slab that fits a lot of screen onto a relatively efficient form factor, and has no trouble getting around bags and pockets thanks to its slim profile and rounded edges. I especially like the nearly flat camera housing, which is the subtlest I’ve seen on a smartphone this year.
The cameras therein may not be amazing (more on that later), but having a phone that almost lays flat on a table feels like some kind of nostalgia trip, especially compared to the awkwardly rocking iPhone, Samsung, and OnePlus flagships we’ve gotten used to. The ports and buttons are as basic as they come but the Reno 12 FS isn’t trying to be much more than usable, and at this price point that’s all I’d expect.
The circular camera module holds another secret, however. Around this housing lies a ring of LEDs, which Oppo calls the Breathing Light. This refers to the light’s ability to react to different sources of sound and information. It’ll flicker in time with music, for example, and fill up as the phone charges.
The Breathing Light is a surprisingly fun addition that adds a lot to what is otherwise essentially just a thin ingot. It’s not made of the most premium materials, with a rear panel that creates a weird amount of friction in the hand and plastic rails that pick up nicks and dents easily. The creatively titled Black Green color is the only option, and luckily exactly to my taste, but if you’re into other colors you’re out of luck.
The camera module follows the Xiaomi 14T school of thought by giving the flash its own lens-sized ring. I’m not opposed to the symmetry this provides, but it feels slightly like an effort to make the Reno 12 FS 5G seem more premium than it actually is. The same could be said for the phone’s curved bezels, which actually hold up a flat screen. It would be more reassuring to see a simpler design and more investment in performance: nobody is expecting a work of art at this price point anyhow.
Design score: 3.5 / 5
Oppo Reno 12 FS 5G review: Display
- 1080 x 2400 resolution
- 120Hz refresh rate
- Peak brightness of 2100 nits
The Oppo Reno12 FS 5G comes equipped with an excellent 6.67-inch FHD+ OLED display, with a 120Hz refresh rate. It is easily the phone’s biggest selling point after its bargain price. For the money, this is a beautiful panel that’s ideal for games, watching videos, or simply scrolling through posts and articles.
With a maximum local brightness of 2100 nits, the Reno 12 FS gets plenty bright, and can just about hold its own in direct sunlight. In fact, I’d recommend using it at higher brightness levels most of the time, as colors can lose contrast and saturation towards the darker end of the slider. Colors are noticeably deeper here than on other displays, which will be a knock or a boost depending on taste.
The display feels responsive to use, which pays off during gaming sessions. Oppo is very good at shaving unnecessary milliseconds off of everyday tasks, and this display works in tandem with the smoothness of ColorOS to provide a genuinely nice experience when the hardware can keep up. It even comes fitted with a screen protector! There are panels with richer colors and sharper images, but for £299 this is one of the best you’ll get.
Display score: 4 / 5
Oppo Reno 12 FS 5G review: Software
- Android 14 with ColorOS 14
- Absolutely full of bloatware
- Otherwise solid with great customization options
The software experience on the Oppo Reno 12 FS 5G makes the most of the phone’s limited hardware. ColorOS is fast becoming my favorite implementation of Android thanks to its swift navigation, easy-to-use settings, and exceptional customization options. However, as with other Oppo phones, what could be an entirely slick experience is marred by an unfortunate amount of bloatware.
Though the Reno 12 FS isn’t exactly a fast phone, ColorOS is generally responsive and loaded with useful options. There is some unpredictable slowdown in the UI, though, which is either down to hardware limitations or poor optimization. The phone comes loaded with Google Gemini, but not Circle to Search, and the pre-installed Oppo apps are fine, though most users will defer to Google’s options instead.
On the topic of apps, the amount of bloatware here really is an issue. Switching on the phone for the first time almost felt like I’d picked up someone else’s handset by mistake, with the pages of the homescreen taken up by apps and games I’d never heard of. The most offensive of these are the ones that are blatant advertisements – this robs the setup experience of its sheen and the user of a sense of proper ownership.
Some of that ownership can be reclaimed with the stellar customization options on the Reno 12 FS. ColorOS has some of the best wallpapers and theme settings of any phone OS I’ve used, Android or no, and they really bring the Reno12 FS to life. There are uniquely generated lock screens, wallpapers that react to your taps, and plenty of font options.
As a side note, The Oppo Reno 12 FS 5G is also the only phone I’ve ever used that has a 300% volume option. Pushing the volume past the normal maximum adds a menacing red “300%” to the top of the bar. The next time someone tells you “it goes up to 11”, you can tell them your phone goes up to 300.
Software score: 3 / 5
Oppo Reno 12 FS 5G review: Cameras
- 50MP wide camera
- 8MP ultrawide camera
- 2MP macro camera
The cameras on the Oppo Reno 12 FS 5G are, frankly, not great. Even holding the phone steady in brightly-lit conditions will produce images that range from just serviceable to unimpressive. It’s honestly disappointing that a 50MP main camera could produce pictures that are so lacking in detail – a reminder that resolution isn’t everything.
Using the camera app is no chore as it comes replete with plenty of options and modes, but the viewfinder consistently displays a grainy and unattractive image. The phone can produce decent final images if you give it a lot of light, but even these show a huge disparity from the preview, which leads me to believe there’s some very active post-processing going on. This theory is somewhat confirmed by the blurriness you’ll see in tree branches and grasses.
I don’t want to come down too hard on the Reno 12 FS, because it is firmly a budget phone, but some of the best cheap phones offer more in this department (the Samsung Galaxy A35 comes to mind). The secondary cameras on the Reno 12 FS – an 8MP ultra-wide and 2MP macro camera – are especially rough, to the point that I question why they were even included.
Still, for capturing home photos and videos, scanning documents, and the occasional holiday snap, the Oppo Reno 12 FS will manage. The selfie camera is also fine, but again doesn’t seem to live up to its 32MP resolution, and video recording at 1080p 60fps is serviceable. The Reno 12 FS doesn’t offer an offensively barebones experience, but those who care about photography should definitely look elsewhere.
Camera score: 2 / 5

Oppo Reno 12 FS 5G review: Performance
- MediaTek Dimensity 6300
- GPU: Mali G57 MC2
- 12GB of RAM
The Oppo Reno 12 FS is something of an oddball performance wise. I’ve managed to get smooth 30fps gameplay from it when booting up Call of Duty Mobile, even in extended sessions, and yet it’ll stutter randomly when swiping into the discover tab or opening YouTube. It’s bothersome, but the slowdown isn’t prevalent enough to ruin an otherwise usable device. Calls are clear and messages are delivered without issue.
The Reno12 FS runs on the MediaTek Dimensity 6300 chipset and comes equipped with a very healthy 12GB of RAM. That’s a reasonable handful of silicon at this price, and I’m especially impressed by the large amount of memory on offer. It shows in the phone’s surprising capacity for multitasking; I’ve yet to have an app crash on me.
Coming from a premium handset, the Reno 12 FS is noticeably slower to open apps, scroll through web pages, and complete searches. I can quite easily get the phone to stutter while switching between apps, too. From a more neutral perspective, the phone is powerful enough for 90% of what people use their phones for, and again I have to consider the price point. The Reno 12 FS finds a reasonable balance.
Performance score: 3 / 5
Oppo Reno 12 FS 5G review: Battery
- Excellent battery life with monstrous standby times
- Confidently an all-day phone
- 5,000 mAh capacity
The Oppo Reno12 FS 5G has a truly excellent battery life, bolstered by absolutely ridiculous standby times. I tested the Reno12 FS intermittently over the course of multiple weeks, and was frequently surprised by picking up a still-charged phone after a week or two away. In daily use, the efficient MediaTek chipset sips at the battery, never dropping by an alarming amount when browsing the web or social media. A 5,000 mAh cell powering a 1080p display is bound to last a while, but the Reno 12 FS still manages to impress.
In normal use, the Reno 12 FS offers a reassuring amount of battery, but when put to one side, the Reno 12 FS just refuses to run out of power. I appreciate standby times aren’t always at the front of buyer’s minds, but I’d be remiss to not mention it in this case – the phone seems to take up between 5% and 10% of its charge per day in standby.
When it does eventually come time to top up, the Reno 12 FS isn’t so impressive. The phone charges via USB-C and doesn’t support wireless charging. An official charging speed isn’t listed, but when plugged in to my 80W SUPERVOOC brick the phone says it’s charging at 45W – a solid power draw by any measure.
Battery score: 4 / 5

Buy it if…
I used the Oppo Reno 12 FS 5G intermittently over the course of several weeks, doing the things we do every day with our smartphones – making calls, sending messages, scrolling through the internet, taking photos, watching videos, listening to music, and playing games. I then considered my findings against the price point of the phone, applying my prior review experience and in-depth knowledge of smartphone specs to review the handset.
