Xiaomi 15 Review: Sleek, Smart, Super Fast

The Xiaomi 15 stands out as a compact flagship smartphone, delivering top-tier performance within a sleek design. This comprehensive review explores its design, display, performance, camera capabilities, battery life, software features, and overall value.
Design and Build Quality
Xiaomi has embraced a minimalist approach with the 15, resulting in an ergonomic and visually appealing device. The aluminum chassis weighs approximately 191 grams, balancing durability and comfort. A subtle matte finish enhances grip and minimizes fingerprint smudges. The device also boasts an IP68 rating, ensuring resistance to dust and water. However, the design closely mirrors its predecessor, the Xiaomi 14, which may not appeal to those seeking a fresh look.
Display
The Xiaomi 15 features a 6.36-inch AMOLED display with a resolution of 2670 x 1200 pixels. It supports a 120Hz refresh rate, delivering smooth visuals, and achieves a peak brightness of 3,200 nits, enhancing readability under direct sunlight. Compatibility with HDR10, HDR10+, and Dolby Vision ensures vibrant and dynamic color reproduction. The uniformly slim bezels and responsive ultrasonic fingerprint sensor embedded beneath the display further contribute to an immersive user experience.
Performance
Powered by the Qualcomm Snapdragon 8 Elite chipset, the Xiaomi 15 comes with 12GB of RAM and storage options ranging from 256GB to 1TB. This configuration ensures seamless multitasking and efficient handling of resource-intensive applications. Benchmark tests position the device alongside other flagship models, such as the OnePlus 13 and Samsung Galaxy S25, underscoring its robust performance capabilities.
Camera System
In collaboration with Leica, Xiaomi has equipped the 15 with a versatile triple-camera setup:
- Primary Camera: 50MP sensor with an f/1.6 aperture, featuring Optical Image Stabilization (OIS) for crisp and clear images.
- Ultra-Wide Camera: 50MP sensor with an f/2.2 aperture, capturing expansive scenes with minimal distortion.
- Telephoto Camera: 50MP sensor with an f/2.0 aperture, offering 3x optical zoom and OIS support for detailed distant shots.
The front-facing 32MP camera caters to high-quality selfies and video calls. Daylight photography yields sharp images with accurate color reproduction and impressive dynamic range. However, some users have reported occasional issues with contrast and exposure, particularly in backlit conditions, necessitating multiple attempts to achieve the desired shot. Low-light performance is commendable, especially when utilizing the dedicated night mode, which effectively manages light sources and enhances detail.
Battery Life and Charging
The device houses a 5,240mAh battery, a notable upgrade from its predecessor, contributing to extended usage times. In standardized battery tests, the Xiaomi 15 outperformed several competitors, including the OnePlus 13 and OPPO Find X8 Pro. The inclusion of 90W wired charging enables rapid replenishment, with the battery reaching full capacity from 20% in approximately 38 minutes.
Software and AI Features
Running on Android 15 with Xiaomi’s HyperOS 2.0 overlay, the Xiaomi 15 offers a customizable and user-friendly interface. While the presence of pre-installed applications may initially appear cluttered, users have the option to uninstall non-essential apps. Xiaomi commits to four years of major OS updates and six years of security patches, ensuring sustained software support. The HyperAI suite introduces features such as the Gemini assistant, which can be activated via a long press of the power button, providing assistance with tasks ranging from image creation to planning. Additional AI functionalities include Circle to Search, AI writing tools, AI Erase Pro, and AI Translate, enhancing the overall user experience.
User Feedback
User reviews have generally been positive, highlighting the device’s performance, display quality, and battery life. However, some users have expressed concerns regarding the removal of certain AI features, such as dynamic wallpapers, though these can be restored through a factory reset, reported by GSMArena.
Conclusion
The Xiaomi 15 stands out as a compelling option for those seeking a compact flagship smartphone that does not compromise on performance or features. Its combination of a high-quality display, robust processing power, versatile camera system, and innovative AI integrations positions it competitively within the market. While certain design elements may feel iterative, and minor software issues persist, the overall value proposition remains strong, making the Xiaomi 15 a worthy consideration for discerning consumers.
