Case and equipment - Outdated USB port
Xiaomi's Redmi 12C is an inexpensive smartphone that can be purchased for well under 200 Euros (~$200), depending on the storage configuration.
Xiaomi offers four color options: dark gray, purple, mint green, and blue. The back is made of plastic and has a palpable stripe pattern, like the predecessor Redmi 10C. The camera module is still very bulky, but it has now been partially adapted to the back in terms of color to look more discreet.
The casing's stability is okay, but quiet creaking noises can be heard when twisting. The screen's edges are also a bit sharp.
Three different storage configurations can be found on Xiaomi's website:
- 3 GB RAM / 32 GB mass storage: 150 Euro
- 3 GB RAM / 64 GB mass storage: 170 Euro (~$570)
- 4 GB RAM / 128 GB mass storage: 200 Euro
Thanks to promotional coupons, however, you can get the smartphone cheaper, and the Redmi 12C is also sold with a significant discount on the rest of the Internet.
We do not understand how Xiaomi can install a microUSB port in the Redmi 12C in 2023. We thought that the time of the confusing variety of ports would finally be over, especially since even the Redmi 10C already had a USB-C port.
The microSD card reader can be used in addition to 2 nano-SIMs, though it is not the fastest in the tests with our reference card Angelbird V60.

Communication, software and operation - Update promise for the software
The WiFi 5 module in the Redmi 12C does a slightly better job than in the predecessor, but it cannot quite keep up with other devices in the price range in terms of receiving speed. This is mainly due to a short drop in the transfer rate, which we can observe again and again at different points even when repeating the test.
The Xiaomi Phone can use 4G as the fastest mobile network and comes with the necessary frequencies for Central Europe. For further trips, you should check in advance which LTE bands you need in the host country and whether the Redmi 12C supports them. The reception quality in the mobile network is decent but cannot keep up with high-end phones.
The software is called MiUI 13, but it is still based on Android 12. The good update promise of 2 Android versions that Xiaomi makes for this phone therefore only extends to Android 14. At least the security patches are renewed quite regularly: every 3 months; they were from March 2023 on our device, which is fairly up-to-date at the time of testing.
The fingerprint sensor is integrated into the camera module on the back. It unlocks the smartphone quite reliably after a short wait. Face recognition is also possible, but it is software-based and thus not as secure.

Cameras - The standard sensor of the price range
Like numerous other inexpensive phones, the Redmi 12C uses Samsung's Isocell JN1 as the main camera's image sensor. The additional camera now only has a 0.1-megapixel lens, but it cannot be used to create photos anyway and only provides additional data for portrait mode.
Main camera takes partly blurry pictures, and the brightness also leaves a lot to be desired. This is not only noticed in daylight but also dark lighting conditions and strong contrasts. Bright areas are over-brightened, while dark ones hardly show any pattern in the photo. The camera is also a bit blurry in full studio lighting in the lab, but the contrasts are acceptable here.
The selfie camera is located in a waterdrop notch at the top of the screen. It has a resolution of 5 megapixels. The resulting photos look quite bright at first glance, but they do not show any drawing, especially in dark areas, and the details are rather poor when enlarged.
Overall, the cameras of the Redmi 12C are on par with the competition.

Display - More brightness and pixels would have been nice
Xiaomi would have had a chance to stand out with the screen: Full HD screens are definitely possible in this price range, like the Galaxy A13 4G or the Poco M5, or very bright screens like in the Moto G13.
However, the manufacturer does without that and installs a 720p screen with a brightness that is even below 400 cd/m² on average in our tests. Thus it is often difficult to see anything on the screen outdoors or in bright rooms.
We did not notice PWM, but a visible color cast into purple in the grayscale. Overall, the screen's color accuracy is okay.

Performance, emissions and battery life - Good performance, good stamina
With the Helio G85 from MediaTek, a former mid-range SoC now also arrives in phones of the lower price regions. Thus, the Redmi 12C actually proves to be much stronger than the Redmi 10C. The Xiaomi phone also offers a lot of power in direct comparison with other inexpensive phones.
It runs quite smoothly in most apps in everyday use. You only experience performance problems when you want to run several programs simultaneously or install very complex apps. However, you have to make do with the slow eMMC flash, which makes loading times and data transfers a bit longer.
The phone heats up to 44.7 °C at room temperature with the heavy load. This means temperature could increase even more on hot days and become unpleasant. However, strong heat development does not affect the performance: the phone hardly shows any losses in the 3DMark stress test.
Small speaker on the lower edge does a pretty good job: it does not distort even at maximum volume, reproduces voices well, and only sounds slightly muffled. Of course, you should not expect a hi-fi sound. External speakers or headphones, which can be connected via a 3.5 mm jack or Bluetooth, are needed for better quality. The phone supports many Bluetooth codecs, including up-to-date ones like aptX TWS+ or LHDC v3/v4.
The 5,000 mAh battery has remained, but Xiaomi has shortened the charging power to 10 watts, while on the Redmi 10C, 18 watts were still possible. The runtimes have improved slightly and are now 15:33 hours in our Wi-Fi test. The smartphone cannot keep up with the Moto G13, but it still delivers very good runtimes for its price range.

Verdict - Xiaomi takes a step backwards
Xiaomi renews its budget phone with the Redmi 12C, but cuts some corners: with slower storage, longer charging times, and a microUSB port (!), the Redmi 12C falls behind its predecessor, but also other smartphones in its price range.
Why Xiaomi made this decision is a good question. Perhaps it is based on the fact that customers who buy a smartphone in this price range are not very interested in technical details and hardly compare the device with other phones. However, it is a shame because the Redmi 10C was a step in the right direction, whereas the Redmi 12C looks like a clear step backwards.
Apart from that, the screen could be brighter and strong heating under high load has to be expected as well. However, the performance rates are appropriate for a device in this price range, and the battery runtimes of over 15 hours in our Wi-Fi test are also convincing. The smartphone also comes with a lot of storage on request.
The Redmi 12C offers decent performance rates, good runtimes, and NFC at a relatively low price, but there are strong alternatives.
The predecessor Redmi 10C is now available with a generous 128 GB of storage for little money, for example, for just under 150 Euros at notebooksbilliger.de. We also liked the Motorola Moto G13, although the update supply is unclear.
Price and availability
The Redmi 12C costs between 150 and 200 Euros at the time of testing directly from the manufacturer depending on the memory configuration. Discounts are also available here from time to time.
However, the Redmi 12C is available for much less at other online retailers: for example, the 32 GB version is available at amazon.de for just under 125 Euros. The 64 GB version costs only 5 Euros more at amazon.de.
The 128 GB version is already available for 137 Euros at amazon.de, while our lender cyberport.de charges just under 160 Euros.
