The world of mid-range smartphones has undergone a remarkable evolution, especially with the arrival of models like the Poco X2 and the Redmi K30 4G . Both devices, firmly rooted in the Xiaomi brand, stand out for offering a set of advanced features at highly competitive prices. However, are they really the same phone with different names? Are there practical differences beyond branding? In this comprehensive review, we cover all the features, strengths, equipment, user experience, and, above all, the most relevant differences and similarities between the Poco X2 and the Redmi K30 4G.
Poco X2 and Redmi K30 4G: Origin, strategy and positioning
The Poco brand emerged as a subsidiary aimed at attracting users interested in the best balance between price and performance. After the resounding success of the Poco F1 , many eagerly awaited its successor. In a strategic move, Poco decided to become independent to forge its own identity, although its initial releases maintained close ties with Xiaomi, particularly with the Redmi line.
The Poco X2 , unveiled after months of speculation, sparked intense debate when it was confirmed that it was essentially a rebranded Redmi K30 4G . This rebranding approach is common in the industry and allows successful products to be adapted to different markets and audiences, but it also generates skepticism among fans who expected more significant improvements over its flagship predecessor. However, the Poco X2 not only uses the K30 4G as a base, but also reaffirms a highly competitive value proposition in the mid-range market, where specifications and price are key factors.

Both the Poco X2 and the Redmi K30 4G share identical dimensions ( 165,3 x 76,6 x 8,8 mm and 208 grams), along with a construction that uses glass on both the front and back , protected by Corning Gorilla Glass. This abandons the plastic finish of the Poco F1, providing a premium feel and appearance, essential for many current buyers.
The fingerprint reader is located on the side/integrated into the power button, which improves ergonomics for everyday use. The devices have a modern look thanks to their curves and the vertical arrangement of the rear camera module, as well as their colors and visual details.
Display: 120Hz fluidity in the mid-range
One of the most notable differentiating features of these models is their 6,67-inch IPS LCD screen with Full HD+ resolution (1080 x 2400 pixels) and a remarkable 120Hz refresh rate . This panel, in a 20:9 aspect ratio and with HDR10 support, provides a smoother and more dynamic visual experience, especially useful for gaming and navigating the interface.
The debate between LCD and AMOLED panels continues, however, Poco and Redmi's choice of a high refresh rate LCD is clearly aimed at users who demand the most demanding gaming performance and fluidity. While slightly sacrificing the deep blacks and lower power consumption offered by AMOLEDs, they gain in natural colors and smooth motion. The screen, protected by Gorilla Glass, meets the protection and durability standards demanded by today's consumers.
The integration of a dual punch-hole cutout for the front cameras in the upper right corner optimizes screen real estate and adds a distinctive touch to the overall design. It's worth noting that both models feature a pixel density of 395 ppi and up to 16 million colors, achieving excellent image and video quality.
Processor and performance: Snapdragon 730G as the gaming heart
Inside both devices, we find a Qualcomm Snapdragon 730G processor clocked at 2.2GHz, paired with an Adreno 618 GPU . This combination clearly places them in the upper mid-range, with enough power to run demanding games, multitask applications, and handle everyday tasks smoothly.
The Snapdragon 730G, specifically designed for the gaming market, offers advantages such as an overclockable GPU, support for advanced rendering technologies, and energy efficiency, placing both models in a prominent position against direct competitors. This chip is comparable in power to top-of-the-line SoCs from previous years, ensuring longevity and good performance even after several years of use.

- 6GB or 8GB of LPDDR4X RAM, ensuring fluidity even during intensive multitasking.
- 64GB, 128GB, or 256GB of UFS 2.1 internal storage, fast and efficient for reading and writing data.
- Expansion via microSD cards up to 512GB on the Poco X2 and up to 256GB on the Redmi K30 4G, adding extra versatility for those who handle large volumes of multimedia files.
The ability to expand storage provides a considerable practical advantage , especially for those who want to store high-resolution videos and large games.
Operating system and user experience
Both models come with Android 10 customized with MIUI 11. The Poco X2 also incorporates the MIUI for POCO layer , which adjusts certain visual and navigation aspects to offer a cleaner experience closer to stock Android, while maintaining all the customization, optimization, and security features of the MIUI platform.
The user experience is characterized by smooth transitions taking advantage of the panel's 120Hz refresh rate, as well as offering a set of useful pre-installed apps and the ability to manage notifications and permissions in detail.
Cameras: Quad rear sensor with Sony IMX686 and versatile selfies
The photographic aspect is one of the strong points of both devices, equipped with a versatile quad-camera system:
- 686MP Sony IMX64 (f/1.9) as the main sensor, 26mm wide-angle, 1/1.72″ sensor size, 0.8µm pixels and phase detection autofocus (PDAF).
- 8MP ultra wide angle (f/2.2), 120º coverage and 1.12µm pixel size, ideal for capturing landscapes or groups.
- 2MP macro lens (f/2.4), for close-up captures with an appreciable level of detail.
- 2MP depth sensor (f/2.4), which improves portraits and the bokeh effect.
The camera module allows 4K video recording at 30fps, Full HD at 120fps and slow motion at 960fps thanks to the presence of gyro-EIS, an electronic stabilizer that improves the smoothness of the clips.
For the front, both phones integrate a dual camera:
- 20MP Main (f/2.2), 27mm wide angle, 1/3.4″ sensor size and 0.8µm.
