Technical Specifications
At the end of August 2025, Xiaomi launched its new models, the Redmi 15C and Redmi 15 (available in both 4G and 5G variants). These devices are positioned just below the Redmi Note 15, providing a comprehensive and affordable range of smartphones.
We had the opportunity to review the 5G version of the Redmi 15, which is attractively priced at 223 euros, especially considering it features a powerful 7000 mAh battery.

Design
The Xiaomi Redmi 15 almost reaches the phablet category with its 6.9-inch screen, measuring 171.08 x 82.05 x 8.55 mm. It’s a relatively large device but not overly thick, and it weighs 224 grams. The front design is fairly standard with clean lines and moderate bezels (the screen constitutes 85.7% of the front surface). At the top of the display, there’s a central punch-hole for the selfie camera.
The back of the device is flat with slightly curved edges and a satin-like finish that resists fingerprint smudges. The Redmi 15 is available in green, gray, and black, with the green model featuring a slightly marbled surface.
The camera module is prominent, encased in a smooth, metallic-like surface that adds to the device’s aesthetic appeal. However, the camera bump can cause the phone to wobble when placed on flat surfaces. The edges of the phone are flat and house the power and volume buttons on the right side, which are comfortably placed for easy reach.
The bottom edge includes a USB-C charging port and a single speaker output. Despite its robust design, Xiaomi has not specified the level of screen protection, but the device does carry an IP64 rating, indicating splash resistance.
Display
The Redmi 15 features a large LCD screen with a resolution of 2340 x 1080 pixels, resulting in a pixel density of 374 PPI. The refresh rate varies between 60 and 144 Hz, providing a decent range for different types of content.
Color accuracy is fair with a Delta E average of 3.29, slightly above the ideal threshold of 3. The color temperature is a bit on the cool side at 7112 K (versus the optimal 6500 K), leading to a slight blue tint, particularly noticeable on white backgrounds.
The contrast ratio stands at 1315:1, which is adequate for an LCD panel but falls short when compared to some competitors. Color coverage is modest with 132% of BT.709, 89% of DCI-P3, and 50% of BT.2020, which are acceptable figures for an entry-level smartphone.
Brightness peaks at 709 nits in SDR and 736 nits in HDR, sufficient for comfortable indoor use and overcast outdoor conditions. However, in direct sunlight, the viewing experience is less satisfactory. The brightness and contrast levels do not fully support high-quality HDR content viewing, even in complete darkness.
Performance
The Xiaomi Redmi 15 is powered by a Snapdragon 685 SoC, an octa-core processor built on the 6 nm process. It is paired with 8 GB of LPDDR4X RAM, an Adreno 619 GPU, and 256 GB of UFS 2.2 storage, expandable via microSD. In this price range, the Redmi 15 holds its own but does not stand out in terms of raw performance.
The device handles Android smoothly, with apps opening without significant delays. However, occasional micro-lags are noticeable. The phone is adequate for everyday tasks like browsing, streaming, and social media but is not suited for heavy editing or 4K video editing.
In gaming, we tested Fortnite at medium settings, where the frame rate hovered around 30 fps but often dropped to between 20 and 30 fps, with frequent dips below 20 fps. Lowering the quality settings improved stability, but the game still experienced frame drops during intense action.
For demanding 3D games, the Redmi 15 might not be the best choice. However, it handles casual and 2D gaming adequately. Given its price point of 223 euros, it offers reasonable performance.
The device manages heat well, even under intense use, with the CPU maintaining stable performance without significant thermal throttling.
Software
The Redmi 15 runs Android 15 topped with Xiaomi’s HyperOS 2, a combination that offers extensive customization options. Users can personalize themes, icons, and fonts to suit their preferences.
The phone includes a comprehensive set of features appropriate for its price range, though AI capabilities are limited to basic functions like Gemini and Circle to Search. Advanced AI features are rare in this segment.
A positive aspect is the ability to select which apps to install during the initial setup, helping avoid bloatware and excessive notifications. However, Xiaomi still pre-installs some unwanted apps that users might need to uninstall manually.
Regarding updates, Xiaomi promises four years of Android updates and six years of security patches, which is commendable for a smartphone priced under 250 euros.
Camera
The Redmi 15’s camera setup includes two lenses:
– A 50 MP main sensor with an f/1.8 aperture
– An auxiliary AI sensor, though detailed specifications are not provided
Main Camera
Under good lighting conditions, the main camera performs competently, producing images with natural but somewhat muted colors. Photos often appear slightly underexposed, resulting in a dull look. Detail is generally preserved, although finer details like flower pistils quickly blur. Noise is minimal but does affect micro-details.
This issue is more pronounced in fine textures; coarser textures like stone fare better. The gradual contrast can lack subtlety, and backlighting often introduces lens flares and a tendency toward overexposure.
The Redmi 15 struggles in low-light conditions. It can manage in areas with strong street lighting, as shown in the photos of the station and the bridge below, where it captures passable images. However, even on the phone’s screen, noticeable noise is evident.
When lighting is insufficient, detail quality collapses, noise becomes pervasive, and colors often shift toward orange. The night mode should be used only under favorable conditions; otherwise, it’s best avoided. Additionally, stability during shooting is crucial to avoid blurry photos.
Portrait Mode
Portrait mode is surprisingly effective. Edge detection is generally accurate, even in challenging conditions such as a backlit cap. While the color accuracy mirrors that seen in the main camera—mostly accurate but slightly flat—the images tend to be slightly underexposed, likely due to uncertain handling of bright highlights.
In dimmer settings, portraits maintain cleanliness. Fine details are captured well, provided you don’t zoom into the image. However, noticeable noise can obscure finer textures such as fabric or facial hair. The bokeh effect is well-managed, appearing more refined in well-lit environments.
Zoom
The camera offers purely digital zoom, ranging from 2x to 10x. At 2x, the color profile subtly shifts, and the image appears paler than those captured with the main sensor. While the quality degradation is noticeable, the image remains usable.
At 4x zoom, the loss of detail becomes apparent. Noise begins to accumulate, and finer details, like the clovers at the bottom of the image, lose clarity. The color shifts further, becoming lighter and less saturated, but not drastically so.
Beyond 8x and 10x zoom, only photos taken in excellent lighting conditions remain passable. In these settings, details deteriorate significantly, but the Redmi 15 still maintains a degree of coherence despite its limitations.
As expected, the main sensor’s performance in night mode does not translate well to the digital zoom. In a well-lit marketplace, noise is quickly evident, accompanied by strong smoothing.
At 4x zoom, these flaws intensify. While details like wall inscriptions remain visible and legible, the noise and smoothing make the image too artificial and unpleasant to view.
Selfie Camera
The selfie camera is perhaps the most pleasant surprise of the Redmi 15. Edge detection is highly accurate, with errors being rare, even in complex areas. Only wildly unruly hair can challenge it. In terms of sharpness, the selfie camera offers better definition than the rear sensor. Beard hairs are well-defined, with digital smoothing present but not overly aggressive—it softens pores without erasing skin texture entirely.
Micro-details are present but sometimes lack precision. This is evident in fabrics, where a jacket might lack some texture relief. The bokeh effect is well-controlled, avoiding the trap of excessive blurring. Color accuracy is slightly darker than ideal but remains natural. Skin tones are reasonably accurate, offering a quality that is well above average for this price segment.
Audio
The Redmi 15C’s single speaker performs adequately but without distinction. The audio output focuses mainly on the mids, with bass being notably absent. Highs can be shrill and become unpleasant at high volumes.
The speaker quickly exhibits distortion as the volume increases. This limitation makes the speaker suitable only for occasional use. The lack of a headphone jack is a notable drawback, although Bluetooth headphones are an option. However, the absence of wired audio connectivity remains a point of frustration.
Network and Communication
The Redmi 15 supports all major 4G and 5G bands available in France. It accommodates dual SIMs or a combination of one SIM and a microSD card. For geolocation, it relies on GPS, Beidou, Galileo, and GLONASS technologies. Additionally, it supports NFC, Bluetooth 5.1, and Wi-Fi 6, ensuring comprehensive connectivity options.
Battery
The Redmi 15’s 7000 mAh battery is exceptional for its price range of under 300 euros. In our PCMark battery test, the device lasted for 17 hours and 56 minutes, an impressive result. In real-world usage, the smartphone easily sustains a day and a half to two days on a single charge under mixed conditions (web browsing, social media, photography, streaming, and light gaming).
Even under more intensive use, it can last a full day without needing a recharge. In streaming tests, with the brightness set to 250 nits and volume at 50%, the phone can handle nearly 27 hours of continuous viewing, which is ideal for excessive binge-watching sessions.
Fast charging at 33W is supported, allowing the battery to reach 6% in 5 minutes, 19% in 15 minutes, and 50% in just under 50 minutes. A full charge takes between 1 hour and 30 minutes to 1 hour and 40 minutes, depending on conditions, which is reasonable given the battery’s capacity.
Pricing and Availability
The Xiaomi Redmi 15 is available in green, blue, and black, priced at 223 euros for the 8 GB + 256 GB configuration. It is positioned competitively in the market, offering a solid choice for budget-conscious consumers looking for a capable smartphone with a robust battery life.
The phone can be found at various retailers, with prices varying slightly depending on the seller.
