Display Comparison
Display specifications are not provided, so a direct comparison is limited. However, given the price points, both likely utilize IPS LCD panels. The Redmi Note 12 Pro 4G, being a Xiaomi device, may benefit from more refined color calibration. Bezels are likely comparable, and without refresh rate data, it's difficult to assess smoothness.
Camera Comparison
Camera details are absent beyond the presence of cameras. Assuming typical configurations for this price bracket, the Redmi Note 12 Pro 4G likely benefits from Qualcomm’s image signal processor (ISP), potentially offering superior image processing and noise reduction. Without sensor size or aperture information, it’s impossible to definitively assess image quality, but Xiaomi’s history suggests a focus on camera performance. The Ulefone’s camera system is likely more basic, prioritizing affordability.
Performance
The core difference lies in the chipsets: the Ulefone Note 18 Ultra features the Mediatek Dimensity 720 (7nm) while the Redmi Note 12 Pro 4G uses the Qualcomm Snapdragon 732G (8nm). The Snapdragon 732G, built on an 8nm process, generally offers a slight edge in single-core performance with its 2.2 GHz Kryo 470 Gold cores compared to the Ulefone’s 2.0 GHz Cortex-A76 cores. However, the Dimensity 720’s architecture may provide better multi-core efficiency. The 7nm node of the Dimensity 720 *could* translate to better thermal management under sustained load, potentially reducing throttling during extended gaming sessions, though real-world testing is needed to confirm. Both devices utilize an octa-core configuration, but the architectural differences impact performance characteristics.
Battery Life
The Ulefone Note 18 Ultra boasts a 50:45h endurance rating, suggesting excellent battery life. However, the Redmi Note 12 Pro 4G counters with a significantly faster 67W wired charging solution. While the Ulefone’s 18W charging is adequate, the Redmi Note 12 Pro 4G can likely replenish its battery from 0-100% in under an hour, a substantial convenience advantage. The Ulefone’s 1000 charge cycles also suggest a longer lifespan for the battery itself, mitigating degradation over time.
Buying Guide
Buy the Ulefone Note 18 Ultra if you need exceptional battery endurance and anticipate prolonged use away from power outlets, valuing long-term battery health with its 1000 cycle rating. Buy the Xiaomi Redmi Note 12 Pro 4G if you prioritize rapid charging and quick power top-ups, and value a more streamlined user experience backed by Xiaomi’s established software ecosystem.
