Display Comparison
The Poco X6 Pro boasts a significantly brighter display, reaching a measured peak of 1148 nits. This translates to superior visibility outdoors under direct sunlight compared to the Redmi Note 15 Pro, which lacks specified brightness data but is likely lower. While both utilize LCD technology (assumed based on market positioning), the X6 Pro’s higher brightness is a tangible advantage. We expect both to feature a standard 60Hz or 120Hz refresh rate, but the X6 Pro’s brightness will be the defining factor for outdoor usability.
Camera Comparison
Both phones are expected to feature multi-camera systems, but detailed sensor information is limited. The context data only mentions 'Photo / Video' for the Poco X6 Pro. Given the market segment, we anticipate both will include a primary sensor, ultrawide, and potentially a macro lens. The X6 Pro’s image processing capabilities, powered by the more potent Dimensity 8300 Ultra, are likely to be superior, resulting in better dynamic range and detail in challenging lighting conditions. The absence of specific sensor details makes a definitive camera comparison difficult, but the X6 Pro’s processing power gives it an edge.
Performance
The core difference lies in the chipsets. The Poco X6 Pro’s Dimensity 8300 Ultra (4nm) is a substantial upgrade over the Redmi Note 15 Pro’s Dimensity 7400 Ultra (4nm). The X6 Pro’s CPU configuration – 1x3.35 GHz Cortex-A715, 3x3.20 GHz Cortex-A715, and 4x2.20 GHz Cortex-A510 – offers a more powerful and efficient architecture than the Note 15 Pro’s 4x2.6 GHz Cortex-A78 & 4x2.0 GHz Cortex-A55. This translates to faster app loading times, smoother multitasking, and significantly improved gaming performance. The X6 Pro will handle graphically intensive games at higher settings with less throttling.
Battery Life
The Poco X6 Pro shines in battery charging, supporting 67W wired charging with QC2.0 and PD3.0, achieving a full charge in just 45 minutes. The Redmi Note 15 Pro is limited to 45W wired charging, meaning a significantly longer charging time. While the Note 15 Pro’s battery capacity isn’t specified, the X6 Pro’s active use score of 11:46h demonstrates excellent battery life despite the faster charging. The X6 Pro’s combination of efficient chipset and fast charging provides a more convenient user experience.
Buying Guide
Buy the Xiaomi Redmi Note 15 Pro if you prioritize a balanced feature set and are comfortable with slower charging speeds. It’s ideal for everyday users who value efficiency and a reliable experience. Buy the Xiaomi Poco X6 Pro if you demand maximum performance for gaming or demanding applications, and appreciate the convenience of rapid 67W charging. This phone is geared towards power users and mobile gamers.
Frequently Asked Questions
❓ Will the Poco X6 Pro’s Dimensity 8300 Ultra overheat during prolonged gaming sessions?
While the Dimensity 8300 Ultra is a powerful chip, Xiaomi typically implements effective thermal management solutions in the Poco series. Expect some heat during extended gaming, but the X6 Pro should avoid significant throttling thanks to its efficient 4nm process and likely heat pipe cooling system. Monitoring temperatures during gameplay is recommended.
❓ Is the 67W charging on the Poco X6 Pro compatible with all USB-C chargers?
The Poco X6 Pro supports 67W charging with QC2.0 and PD3.0 protocols. While it will charge with any USB-C charger, you’ll only achieve the full 67W speed with a charger that supports these protocols. Using a standard USB-C charger will result in slower charging times.
❓ Does the Redmi Note 15 Pro support 5G connectivity?
Given the Dimensity 7400 Ultra chipset, the Redmi Note 15 Pro is highly likely to support 5G connectivity. However, specific 5G band support will vary by region. Check the official specifications for your region to confirm compatibility with your carrier.
❓ What kind of storage does the Poco X6 Pro use – UFS 3.1 or UFS 4.0?
Based on the Dimensity 8300 Ultra chipset and the X6 Pro’s positioning, it is expected to utilize UFS 3.1 storage. While UFS 4.0 offers faster speeds, UFS 3.1 still provides excellent performance for app loading and file transfers.
