MagyarXiaomi Redmi 12 smartphone review – A flexible camera system for under US$200
Xiaomi's Redmi series traditionally includes cheaper phones that often have a few special features to offer. The Chinese manufacturer markets the Xiaomi Redmi 12 as having limited protection against water as well as flexible cameras. And at the same time, the phone is supposed to be available for under US$200, while also still offering quite a bit of storage space.
On the other hand, there are lots of other very strong competitors within this price range and more often than not, you have to end up making a few compromises if you decide to purchase such a cheap phone. In this review, we will take a closer look at what you might have to forgo as a potential user of this device.

Case – Sleek glass case
The back and front of the Xiaomi Redmi 12 is made from Gorilla Glass - although, Xiaomi hasn't specified which version. Due to the phone's low price, it is safe to assume this is an older variant, which means you shouldn't rely on complete breakage resistance. Design-wise, the Redmi phone looks really nice - our silver test sample shimmers in lots of different colors and the particles under the glass sparkle.
The sides feature a plastic frame, which is available in black, silver or light blue. The cameras each have their own indentation within the case, meaning there is no singular border around the camera module.
Xiaomi has defined the case as being IP53 certified, so it is relatively well protected against dust, but it is only water resistant and not waterproof. You shouldn't submerge the phone underwater. The back is very stable under pressure and doesn't have any give. Medium pressure on the front penetrates through to the screen's liquid crystal. The Xiaomi phone can hardly be twisted, but it cracks slightly from time to time when you try to do so.
Features – Lots of storage for your money
The Xiaomi Redmi 12 is available in two storage variants:
- 4 GB RAM / 128 GB storage: US$170
- 8 GB RAM / 256 GB storage: US$187
Internationally, you might also be able to find the smaller storage variant with 8 GB RAM.
Thankfully, you don't have to miss out on NFC, meaning you can also utilize payment services such as Google Pay. If you enjoy listening to radio on the go and don't want to use up any of your data, then you can make use of the phone's built-in FM radio.
Another unique feature is the Redmi 12's infrared sensor which allows you to use the smartphone as a remote control for your TV.
microSD card reader
The phone doesn't have a designated microSD slot, so you'll have to decide whether to utilize two SIM slots or to use one for a SIM and one for a microSD. The card reader accepts microSDs with up to 1 TB of storage - although, in our copying test using the reference card Angelbird V60, it proved to be a bit slow.

Cross Platform Disk Test (CPDT)
Software – Android 13 ex works
The Redmi 12 comes with MiUI as an interface which relies on Android 13 - although, it changes the system quite a bit. Fans of pure Android should probably try out MiUI before buying the device, to see if you are okay with all of these changes.
Lots of apps come pre-installed, including third party sponsored apps. At times, ads are shown as part of the system itself, for example on the lock screen or while installing apps.
At the time of testing, the latest security patch was from June 2023, so still relatively up-to-date. In the past, Xiaomi has even provided its cheaper phones with at least 2 years of Android updates and has released regular security patches over the course of many years.
Communication and GNSS – The Redmi 12 with precise locating
With WiFi 5 and data rates of up to 376 MBit/s during our WLAN test using the reference router Asus ROG Rapture AXE11000, the Redmi 12 proves to represent its price category just as expected.
Close to the router, we had full WLAN signal and websites were loaded relatively quickly. With a distance of 10 metres to the router and with 3 walls in between, we started to notice quite a drop in WLAN performance and websites generally took quite a while to load.
Unfortunately, this Redmi 12 doesn't support 5G. In countries outside of Europe, you can find a version which supports this, namely the Redmi 12 5G. All the necessary 4G frequencies are supported, although the phone isn't exactly a global phone. During our two-week test phase, reception was average in total - but we never fully lost reception in inner city areas.
The Redmi 12 supports all the big satellite networks for locating and it connected very quickly when we were outdoors. Here, you can expect to be located within 2 metres. It even supports SBAS, which helps the phone to locate even more precisely.
Let's take a look at how well the Redmi 12 can keep up its location services in practice: To do so, we jumped on our bikes and took with us our Garmin Venu 2 smartwatch as a comparison, as it features extremely exact location services.
As long as streets are quite wide and houses are low, the Redmi 12 has no problems recording your taken route. In narrow city alleyways, it isn't quite as precise, but it is by no means bad. As a result, we could recommend the Redmi 12 to be used for navigating.
Telephone functions and call quality – Clear conversations
Despite the system's big changes, the phone still relies on Google's standard telephone app to make calls.
We liked its call quality with the phone held up to our ear - you can understand the person you are speaking to clearly and loudly if this is required. Our voice was transmitted well. When using the loudspeaker, our calls also sounded clear, although you just have to make sure to talk loudly enough.
Cameras – Flexible and class-typical quality
A wide-angle lens isn't always standard on cheap mid-range devices, and yet the Xiaomi Redmi 12 also features a macro camera in addition to this. Although, the system doesn't switch to these automatically and you have to select macro mode in order to use this lens. Images taken with this are quite low-quality and the wide-angle camera takes quite dark images with low detail levels. A hybrid zoom between the wide-angle and main lenses is available.
The main 50-megapixel camera relies on a Samsung Isocell JN1 as a sensor, which can often be found in cheaper smartphones. The Xiaomi Redmi Note 12 5G, for example, also features this main camera sensor and in total, has a very similar camera setup.
Photos taken on our test device appear a little lifeless and don't show much dynamic in blight and dark areas. Thankfully, the pictures are sharp and have quite good levels of detail. Even in low light conditions, the phone takes decent photos and in totally dark conditions, you can still recognize a few details.
Videos can be recorded with a maximum of 5 megapixels and at 30 fps. The autofocus can be a little slow, but it doesn't ever pump and its lighting adjustment also works well.
The front-facing camera has a resolution of 5 megapixels and at first glance, it takes good selfies which still show one or two details in darker areas, too. If you enlarge the images, then they quickly start to become very grainy.

Choose a scene and navigate within the first image. One click changes the position on touchscreens. One click on the zoomed-in image opens the original in a new window. The first image shows the scaled photograph of the test device.
Main camera flowerMain camera surroundingsMain camera low lightWide-angle
In the lab with good lighting, the main camera can only depict subjects with moderate detail sharpness, but the contrast levels are good. The image content can only be guessed with a lighting strength of only 1 lux.
Accessories and warranty – No power supply included
The Redmi 12 doesn't come delivered with a power supply. Instead, the package includes a silicone case and a headset.
This phone currently isn't covered by Xiaomi's International Warranty Service, as only a select few of their phones are.
Input devices & operation – Accurate fingerprint sensor
The phone's 90-Hz screen can adjust its refresh rate automatically between four levels: 36 Hz/48 Hz/60 Hz/90 Hz. This lets the phone save energy when depicting a still image, while its refresh rate is also good enough to provide smooth operation with quick reaction speeds. The Redmi 12's reactive touchscreen is good and it is sensitive right up to the corners.
Xiaomi has hidden a fingerprint sensor on the right side of the phone within its standby button. It unlocks the phone almost immediately and very reliably. You can also unlock the device using your face - but it only scans 2D images, meaning it is a little susceptible to manipulation.
Display – High resolution, moderate brightness
The phone's IPS screen has a high resolution of 2,460 x 1,080 pixels - within this price range, it isn't uncommon to still see phones with a 720p resolution. Unfortunately, the Redmi 12 lacks a little in brightness, especially compared to the great AMOLED in the similarly priced Redmi Note 12 5G.
Its slightly raised black value also results in poor contrast levels. The display thankfully doesn't show any signs of PWM flickering, but in turn, it only offers moderate reaction speeds.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM not detected |  | ||
In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
In our measurements using a spectrophotometer and the software CalMAN, we noted a minimal yellow tint when depicting white tones, which also represents the screen's largest deviation to the reference color space. Colors are generally depicted very well and the color profile "standard" seems to be the most accurate.

Outside, the screen brightness is sufficient on cloudy days in order to still be able to read from the phone - in direct sunlight, this can get a little tricky.
The possible viewing angles are wide in all directions thanks to IPS technology.
Performance – Enough for everyday use
The installed MediaTek Helio G88 is a typical SoC for cheaper mid-range phones. In our comparison field, the device did quite well in most of the benchmarks - it only had to admit defeat to the Redmi Note 12 5G.
In everyday use, you can't fully avoid some dropped frames but when manoeuvring the system, they don't happen often. More complex apps overwhelm the phone quite quickly.

The phone did well for its price-range in the graphics benchmarks, too. However, it quickly becomes clear that the SoC is better suited for a 720p screen, as the corresponding phones within our comparison field did much better in the onscreen tests.

The eMMC flash in the Xiaomi Redmi 12 is a bit slow. Although it is still acceptable within this price-range, there are a few examples of phones with quicker flash which can transfer files and open apps quicker, such as the Redmi Note 12 5G or the Nokia G22.

Games – Mostly just 30 fps
When gaming, you really shouldn't choose anything more than 30 fps. Of course, there will be some games that can manage 60 fps, but on more complex games such as PUBG Mobile, you can't really get many more frames - even at low detail settings.
We also couldn't achieve anything better than 30 fps and the lowest resolution setting while playing Diablo: Immortal. Furthermore, we noted a graphics bug which renders the game unplayable. We measured the frame rates using GameBench.
Controlling games using the touchscreen and the position sensor worked reliably.
Emissions – The Redmi 12 doesn't get all too warm
Temperature
We measured a peak case temperature of 44.1 °C. This can be felt, but it isn't yet critical. This doesn't have an effect on the device's speed - even after 20 runs of a complex benchmark, the phone still had access to 96 % of its original performance.
(±) The maximum temperature on the upper side is 44 °C / 111 F, compared to the average of 35 °C / 95 F, ranging from 21.9 to 56 °C for the class Smartphone.
(±) The bottom heats up to a maximum of 44.1 °C / 111 F, compared to the average of 33.8 °C / 93 F
(+) In idle usage, the average temperature for the upper side is 24.5 °C / 76 F, compared to the device average of 32.7 °C / 91 F.

The small speaker on the bottom corner of the device does its job quite well - it sounds relatively clear and it doesn't exaggerate the highs. Of course, you should by no means expect some sort of HiFi system, but it is definitely enough to watch some videos or listen to some music occasionally.
The phone has a 3.5 mm jack and Bluetooth, which you can use to connect external audio devices. A great variety of codecs is supported: Aside from SBC and AAC, it also supports all the important aptX codecs, LDAC and LHDC up to version 5.

Battery life – Good stamina
Power consumption
The Redmi 12 seems to be quite frugal under low and very low load, but under high load, it can use quite a bit of power at times.
In order to recharge the device, a charging system with up to 18 watts is installed. While the phone doesn't come with a charger, we used a few chargers from different phones and they were all identified by the Xiaomi Redmi 12, enabling the phone to be charged quickly. It takes a maximum of 2:15 hours to charge the battery completely.

Runtimes
In our WLAN test, the Xiaomi Redmi 12 did quite well with average runtimes of 13:23 hours. You can definitely manage a whole working day on this device, but there are certainly a few other phones within the price range that enable even longer runtimes. Other use scenarios such as watching videos or high load also showed good results, meaning the Redmi phone delivered a good score in total regarding runtimes.

Pros
Cons
Verdict – Attractive and cheap with some highlights
The Xiaomi Redmi 12 looks great and comes with lots of storage space. A few positive aspects deserve to be named, such as its IR blaster and FM radio reception. It also comes with the necessary headset to use as a substitute for an antenna. The inexpensive mid-range phone also offers good runtimes and very precise locating.
The camera is fitted with three decent lenses, making it flexible and - for the price - really quite okay. Its screen could be a little brighter, but all-in-all, it can depict colors quite well. In case you enjoy listening to music, the phone features decent speakers, lots of Bluetooth codecs as well as a 3.5 mm jack.
We find all the bloatware to be a little annoying, which Xiaomi has pre-installed onto the phone. This is even more of a shame because the phone is supposed to receive long and regular operating system updates as well. The smartphone doesn't come with a charger, but this shouldn't be too big an issue, as the device is compatible with all the usual chargers.
The Xiaomi Redmi 12 is an attractive and inexpensive smartphone which may not include 5G, but it can offer lots of storage and precise locating in return.
One of the phone's main competitors actually comes from the same manufacturer: The Xiaomi Redmi Note 12 5G offers faster memory, better performance and 5G. It just isn't quite as nice in looks. If you are looking to spend even less money, then it may be worth taking a look at the Nokia G22.
