Display Comparison
The OnePlus Nord 4 boasts a significantly brighter display, reaching a measured peak of 1163 nits. This translates to superior visibility outdoors under direct sunlight compared to the Redmi Note 15 Pro (brightness data unavailable). While both utilize 4nm chipsets, the display’s brightness impacts usability. We expect the Nord 4 to have better color accuracy and contrast, though a direct comparison requires panel analysis. The Redmi Note 15 Pro’s display specs are currently unknown, making it difficult to assess its overall quality.
Camera Comparison
Without detailed camera specifications for the Redmi Note 15 Pro, a direct comparison is limited. However, the market segment suggests both phones will feature multi-camera systems. The Nord 4’s image processing benefits from Qualcomm’s ISP, known for its detail preservation and dynamic range. We anticipate the Nord 4 to excel in low-light photography due to its optimized image signal processing. The Redmi Note 15 Pro will likely focus on offering a versatile camera experience, but may fall short of the Nord 4’s image quality in challenging conditions. Ignoring the likely inclusion of 2MP macro lenses on both devices, the main sensor and its accompanying OIS will be key differentiators.
Performance
The core difference lies in the chipsets: the Redmi Note 15 Pro features the Mediatek Dimensity 7400 Ultra, while the Nord 4 utilizes the Qualcomm Snapdragon 7+ Gen 3. The Snapdragon 7+ Gen 3, with its Cortex-X4 prime core clocked at 2.8 GHz, offers a performance advantage over the Dimensity 7400 Ultra’s Cortex-A78 core (2.6 GHz). The Snapdragon’s architecture, including the A720 and A520 cores, is also more modern, potentially leading to better efficiency. While both are built on a 4nm process, Qualcomm’s optimizations generally result in superior thermal management, crucial for sustained gaming. The Redmi Note 15 Pro’s CPU configuration suggests strong multi-core performance, but the Nord 4’s single-core speed will likely be higher.
Battery Life
The OnePlus Nord 4 shines in battery and charging. Its 14:41h active use score demonstrates excellent endurance. More importantly, the 100W wired charging, with PPS support, can fully charge the device in just 28 minutes – a significant advantage over the Redmi Note 15 Pro’s 45W charging. While the Redmi Note 15 Pro’s battery capacity is unknown, the slower charging speed suggests it may take considerably longer to reach a full charge. The Nord 4’s faster charging is ideal for users who need to quickly top up their battery throughout the day.
Buying Guide
Buy the Xiaomi Redmi Note 15 Pro if you need a feature-rich phone with a focus on value and are comfortable with potentially slower charging speeds. Buy the OnePlus Nord 4 if you prioritize a smoother, more responsive user experience, exceptionally fast 100W charging, and longer sustained performance during demanding tasks like gaming or video editing.
