Xiaomi 15
- Significantly faster 90W wired charging
- Superior battery endurance (63:26h)
- Higher peak display brightness (1517 nits)
- Potential for faster battery degradation due to higher charging speeds
- Software experience may be more feature-rich but less streamlined than OnePlus
OnePlus 13s
- Potentially more refined software experience (OnePlus tradition)
- PPS charging support for optimized charging with compatible chargers
- Slightly more conservative charging approach may extend battery lifespan
- Slower charging speeds (80W wired)
- Battery endurance data unavailable, likely lower than Xiaomi 15
- Display brightness likely lower than Xiaomi 15
Display Comparison
The Xiaomi 15 boasts a peak brightness of 1517 nits, measured, suggesting a significantly more visible display in direct sunlight compared to the OnePlus 13s (brightness data unavailable). While both devices likely utilize advanced panel technologies like LTPO for adaptive refresh rates, the Xiaomi 15’s higher peak brightness provides a tangible advantage for outdoor visibility. The absence of detailed display specs for the OnePlus 13s makes a comprehensive comparison difficult, but the Xiaomi 15 clearly leads in measured brightness.
Camera Comparison
Unfortunately, the provided context data lacks any camera specifications for either device. Given their flagship positioning, both phones are expected to feature multi-camera systems with advanced features like optical image stabilization (OIS). Without sensor size, aperture, or image processing details, a meaningful comparison is impossible. We can speculate that both will offer competitive camera performance, but the specifics remain unknown.
Performance
Both the Xiaomi 15 and OnePlus 13s are equipped with the Qualcomm SM8750-AB Snapdragon 8 Elite (3 nm) chipset, featuring an octa-core CPU configuration of (2x4.32 GHz Oryon V2 Phoenix L + 6x3.53 GHz Oryon V2 Phoenix M). This identical core configuration guarantees virtually identical CPU performance. The 3nm process node promises excellent thermal efficiency, minimizing throttling during sustained workloads. However, the effectiveness of each manufacturer’s cooling solution will ultimately determine real-world sustained performance, a metric not provided in the context data. RAM speed and type (likely LPDDR5x) are also assumed to be comparable.
Battery Life
The Xiaomi 15 demonstrates a clear advantage in battery endurance, achieving a remarkable 63:26h score and 16:28h of active use. This contrasts with the OnePlus 13s, for which battery endurance data is absent. The Xiaomi 15’s charging capabilities are also superior, offering 90W wired charging with PD3.0 and QC3+ support, alongside 50W wireless and 10W reverse wireless charging. The OnePlus 13s offers 80W wired charging with PPS, 18W PD, 18W QC, and 5W reverse wired charging. The Xiaomi 15’s faster wired and wireless charging, combined with its significantly longer endurance, makes it the clear winner for users who demand minimal downtime.
Buying Guide
Buy the Xiaomi 15 if you need the fastest possible charging speeds, maximum battery life, and a display that pushes peak brightness. Buy the OnePlus 13s if you prioritize a streamlined software experience and a slightly more conservative approach to power delivery, potentially favoring long-term battery health over immediate top-ups.
