Display Comparison
While both devices are expected to feature high-refresh-rate AMOLED displays, the provided data doesn't detail screen specifications. However, given their flagship status, both will likely boast vibrant colors and excellent viewing angles. The absence of display data necessitates relying on brand reputation; OnePlus typically prioritizes color accuracy, while Xiaomi often aims for maximum brightness. Expect both to utilize LTPO technology for adaptive refresh rates, optimizing battery consumption.
Camera Comparison
The provided data lacks camera specifications, making a direct comparison impossible. However, Xiaomi's Ultra series historically focuses on camera innovation, suggesting the 15 Ultra may feature a more advanced camera system with larger sensors and more sophisticated image processing. OnePlus has also significantly improved its camera capabilities in recent generations, but typically prioritizes a more natural image profile. Without sensor details, it's difficult to assess which device will excel in low-light performance or dynamic range.
Performance
Both the Xiaomi 15 Ultra and OnePlus 13s are equipped with the Qualcomm SM8750-AB Snapdragon 8 Elite (3nm) chipset, featuring an octa-core CPU configuration of (2x4.32 GHz Oryon V2 Phoenix L + 6x3.53 GHz Oryon V2 Phoenix M). This means raw processing power will be virtually identical. Performance differences will likely stem from thermal management and RAM optimization. The 3nm process node promises improved thermal efficiency, reducing throttling during sustained workloads. The absence of RAM specifications prevents a definitive comparison, but both are expected to utilize LPDDR5x for fast memory access.
Battery Life
The Xiaomi 15 Ultra boasts a significant advantage in battery endurance, achieving 58:58h compared to the OnePlus 13s' unspecified endurance. The 16:13h active use score for the Xiaomi further highlights its superior battery performance. This is coupled with a more versatile charging ecosystem: 90W wired, 80W wireless, and 10W reverse wireless for the Xiaomi versus 80W wired, 33W PPS, 18W PD/QC, and 5W reverse wired for the OnePlus. The Xiaomi’s 80W wireless charging is a standout feature, offering significantly faster wireless top-ups than the OnePlus’s 33W PPS. The Xiaomi also supports both PD3.0 and QC3+ for wider wired charging compatibility.
Buying Guide
Buy the Xiaomi 15 Ultra if you need exceptional battery life, prioritize wireless charging speed, and frequently engage in power-intensive tasks like gaming or video editing. Buy the OnePlus 13s if you value a streamlined software experience, prefer a potentially more compact design (based on brand history), and are comfortable with a slightly less extensive charging ecosystem, focusing on wired speeds.
