OnePlus Ace Pro
- Industry-leading 150W wired charging
- Identical Snapdragon 8+ Gen 1 performance
- Potentially more aggressive pricing (depending on market)
- No wireless charging
- No reverse wireless charging
- Limited information on camera capabilities
Xiaomi 12S Pro
- Fast 120W wired charging
- Convenient 50W wireless charging

- Potentially higher price point
- Image processing may not appeal to all users
Display Comparison
While detailed display specs aren't provided, both phones likely feature high-refresh-rate AMOLED panels, common for this price segment. The absence of LTPO information suggests neither device dynamically adjusts refresh rates for optimal power efficiency. Bezels are expected to be minimal on both, reflecting current flagship design trends. Color accuracy will likely be excellent, though specific calibration details are unavailable. The real-world difference in display quality will likely be minimal for most users.
Camera Comparison
Without detailed camera specifications, a direct comparison is limited. Both phones likely feature multi-camera systems, but the sensor sizes and lens apertures are unknown. The Xiaomi 12S Pro’s history suggests a focus on image processing tuned for natural colors, while OnePlus often leans towards more vibrant, saturated images. The absence of information on Optical Image Stabilization (OIS) makes it difficult to assess low-light performance. Any 2MP macro or depth sensors are likely to offer minimal benefit over software-based solutions.
Performance
Both the OnePlus Ace Pro and Xiaomi 12S Pro utilize the Qualcomm SM8475 Snapdragon 8+ Gen 1 (4nm). This means identical CPU configurations: an octa-core setup with 1x3.19 GHz Cortex-X2, 3x2.75 GHz Cortex-A710, and 4x1.80 GHz Cortex-A510 cores. Performance in CPU-bound tasks will be virtually indistinguishable. The 4nm process node contributes to improved thermal efficiency compared to previous generations, mitigating throttling during sustained workloads. However, thermal management implementation by each manufacturer will play a crucial role in real-world gaming performance. RAM speed (likely LPDDR5X) is also expected to be similar, further minimizing performance gaps.
Battery Life
The OnePlus Ace Pro’s 150W wired charging is its standout feature, promising incredibly fast top-ups. The Xiaomi 12S Pro counters with 120W wired charging, which is still exceptionally fast, but demonstrably slower. The 12S Pro further differentiates itself with 50W wireless charging and 10W reverse wireless charging – features absent on the Ace Pro. The Xiaomi 12S Pro claims a full charge in 19 minutes, while the Ace Pro’s charging time is not specified, but is expected to be even faster. The actual battery capacity (mAh) isn't provided, but the charging speed advantage of the Ace Pro will be noticeable for users who prioritize quick power boosts.
Buying Guide
Buy the OnePlus Ace Pro if you need the absolute fastest wired charging available and prioritize a simple, focused experience. This phone is ideal for users who frequently top up their battery throughout the day and don't rely heavily on wireless charging. Buy the Xiaomi 12S Pro if you value the convenience of both fast 120W wired charging *and* 50W wireless charging, alongside reverse wireless charging capabilities, making it a more versatile power solution for a wider range of devices.
