Display Comparison
Both devices share an 'Infinite' (nominal) contrast ratio, suggesting typical IPS LCD characteristics. However, detailed display specs like peak brightness, color gamut coverage, and refresh rate are missing for the BLU F91. The Poco X4 Pro 5G’s display, while also lacking detailed specs, benefits from Xiaomi’s established display calibration expertise, likely resulting in more accurate colors and better viewing angles. Without further data on the F91, the Poco X4 Pro 5G holds an advantage based on brand reputation and potential for better display quality.
Camera Comparison
Both phones are listed as having 'Photo / Video' capabilities, but specific details are absent. Without sensor size, aperture, or image processing details, a direct comparison is impossible. However, Xiaomi’s image processing algorithms are generally more refined than those found on BLU devices, suggesting the Poco X4 Pro 5G will likely produce more visually appealing photos in a wider range of conditions. The lack of detail on the BLU F91’s camera system makes it difficult to assess its capabilities beyond basic smartphone photography.
Performance
The BLU F91’s Mediatek Dimensity 810 (6nm) features a dual-cluster CPU configuration with 2x2.4 GHz Cortex-A76 cores and 6x2.0 GHz Cortex-A55 cores. The Poco X4 Pro 5G utilizes the Qualcomm Snapdragon 695 5G (6nm) with 2x2.2 GHz Kryo 660 Gold cores and 6x1.7 GHz Kryo 660 Silver cores. While the Dimensity 810 boasts slightly higher peak clock speeds, the Snapdragon 695 often demonstrates superior sustained performance and thermal management due to Qualcomm’s optimized CPU architecture and software integration. The Snapdragon 695’s Adreno 619 GPU is also generally more efficient for gaming than the Mali-G52 MC2 found in the Dimensity 810. The Poco X4 Pro 5G is likely to offer a smoother, more consistent gaming experience.
Battery Life
Both devices achieve an endurance rating of 119 hours, indicating similar overall battery life under typical usage. However, the charging capabilities are drastically different. The BLU F91 offers 18W wired charging, 10W wireless charging, and reverse wired charging. The Poco X4 Pro 5G, in contrast, boasts a blazing-fast 67W wired charging with support for PD3.0 and QC3, achieving 70% charge in 22 minutes and 100% in 41 minutes. This charging speed is a significant advantage for the Poco X4 Pro 5G, minimizing downtime and offering a much more convenient charging experience. The inclusion of wireless and reverse charging on the F91 is a plus, but the slower speeds diminish its practical benefit.
Buying Guide
Buy the BLU F91 if you prioritize raw CPU performance for demanding tasks and appreciate the convenience of wireless charging, even if it's slower. This phone is ideal for users who frequently engage in CPU-intensive applications or prefer a more flexible charging ecosystem. Buy the Xiaomi Poco X4 Pro 5G if you value fast charging, a potentially more stable software experience, and a balanced overall package. This phone is best for users who want a reliable daily driver with minimal downtime spent tethered to a charger.
