Oppo Ace2

  • Blazing-fast 65W wired charging
  • Competitive 40W wireless charging
  • Faster reverse wireless charging (10W)

  • Camera specifications are unknown
  • Display details are limited

Xiaomi Mi 10 Pro 5G

  • High peak display brightness (858 nits)
  • Good battery endurance (101h)
  • Potentially more advanced camera system

  • Slower wired and wireless charging speeds
  • Lower reverse wireless charging speed (5W)

Display Comparison

Both phones utilize high-quality displays, but the Xiaomi Mi 10 Pro edges out the Ace2 with a measured peak brightness of 858 nits. While the Ace2’s display specs aren’t provided, the Mi 10 Pro’s high brightness ensures excellent visibility in direct sunlight. The Mi 10 Pro also boasts an infinite (nominal) contrast ratio, suggesting a superior viewing experience with deeper blacks. However, without knowing the Ace2’s panel technology (LTPO, PWM dimming rate), a definitive judgment on display quality is difficult. The Mi 10 Pro’s higher brightness is a clear advantage for outdoor use.

Camera Comparison

The context data for both phones only states 'Photo / Video' capabilities, lacking specifics on sensor size, aperture, or OIS. Given Xiaomi’s historical focus on camera innovation, the Mi 10 Pro likely features a more sophisticated camera system, potentially with a larger main sensor and more advanced image processing algorithms. However, without concrete specifications, this remains speculative. The absence of detail on the Ace2’s camera suggests it may be a less prominent selling point compared to the Mi 10 Pro.

Performance

Both the Oppo Ace2 and Xiaomi Mi 10 Pro are equipped with the Qualcomm SM8250 Snapdragon 865 5G (7 nm+), featuring the same octa-core CPU configuration (1x2.84 GHz Cortex-A77, 3x2.42 GHz Cortex-A77, and 4x1.80 GHz Cortex-A55). This means raw processing power will be nearly identical. Performance differences will likely stem from thermal management and software optimization. The Ace2’s faster charging could indirectly improve sustained performance by allowing for more frequent top-ups, preventing the battery from being deeply discharged, which can impact CPU throttling. Without detailed thermal testing data, it’s difficult to declare a clear performance winner.

Battery Life

The Xiaomi Mi 10 Pro boasts an endurance rating of 101 hours, indicating a respectable battery life. However, the Oppo Ace2’s charging capabilities are the standout feature. Its 65W wired charging can fully charge the battery in just 30 minutes, while the 40W wireless charging takes 56 minutes. In contrast, the Mi 10 Pro’s 50W wired (with PD3.0) and 30W wireless charging are significantly slower. This difference in charging speed is a major advantage for the Ace2, especially for users who frequently need to quickly replenish their battery. The 10W reversed wireless charging on the Ace2 also surpasses the Mi 10 Pro’s 5W offering.

Buying Guide

Buy the Oppo Ace2 if you need the absolute fastest charging speeds available, both wired and wireless, and value a phone that minimizes downtime. It's ideal for power users who frequently top up their battery throughout the day. Buy the Xiaomi Mi 10 Pro 5G if you prioritize a slightly longer battery endurance rating and potentially a more mature software ecosystem, and are less concerned with achieving the quickest possible charge times.

Frequently Asked Questions

❓ How much faster is the Oppo Ace2's charging compared to the Xiaomi Mi 10 Pro in a real-world scenario?
The Oppo Ace2's 65W charging can take a phone from 0% to 100% in 30 minutes, while the Mi 10 Pro's 50W charging will take considerably longer – likely around 45-60 minutes. This 15-30 minute difference is significant for users who need a quick top-up before heading out.
❓ Does the Snapdragon 865 in either phone exhibit noticeable thermal throttling during extended gaming sessions?
Both phones utilize the same Snapdragon 865 chipset, so throttling potential is similar. However, the Ace2’s faster charging allows for more frequent, shorter charging cycles, potentially keeping the battery cooler and mitigating throttling. Without dedicated thermal testing, it’s difficult to definitively say which phone handles sustained loads better.
❓ Is the difference in wireless charging speed between the Ace2 (40W) and Mi 10 Pro (30W) noticeable for everyday use?
Yes, the 10W difference in wireless charging speed is noticeable. A full wireless charge on the Ace2 will take approximately 56 minutes, while the Mi 10 Pro will take closer to 70-80 minutes. This can be a significant convenience factor for users who primarily charge their phones wirelessly overnight.
