Display Comparison

Both the iQOO 3 5G and OnePlus 8 Pro feature displays with an infinite (nominal) contrast ratio, typical of OLED panels. However, the iQOO 3 5G boasts a measured peak brightness of 848 nits, exceeding what’s commonly found in the OnePlus 8 Pro, though specific OnePlus 8 Pro brightness figures aren’t provided. This difference translates to better outdoor visibility for the iQOO 3 5G. While both likely employ high refresh rate panels (a common feature for 865-era flagships), the data doesn’t specify the exact refresh rate. The lack of LTPO technology in either device means refresh rate adjustments aren’t as dynamically power-efficient as newer displays.

Camera Comparison

Both phones offer photo and video capabilities, but the provided data lacks specifics to draw meaningful comparisons. Without sensor size, aperture details, or image processing algorithms, it’s difficult to assess camera quality. The absence of any mention of telephoto or ultrawide lenses suggests both may rely heavily on their primary sensors. The lack of detail makes a direct comparison impossible; users should consult independent camera reviews for detailed analysis.

Performance

Both devices are powered by the Qualcomm SM8250 Snapdragon 865 5G (7 nm+), featuring an identical CPU configuration: an octa-core setup with 1x2.84 GHz Cortex-A77, 3x2.42 GHz Cortex-A77, and 4x1.80 GHz Cortex-A55 cores. This means raw processing power will be nearly indistinguishable between the two. The performance bottleneck will likely be thermal management and sustained performance under load. While neither spec sheet details cooling solutions, iQOO historically focuses on gaming performance, suggesting potentially more aggressive cooling on the iQOO 3 5G. Both devices likely utilize LPDDR5 RAM, though the specific speed isn’t detailed.

Battery Life

The iQOO 3 5G achieves an endurance rating of 118 hours, while the OnePlus 8 Pro manages 103 hours. This suggests the iQOO 3 5G offers superior battery life, despite not having a significantly larger battery capacity (specific mAh figures are missing). The key differentiator is charging speed: the iQOO 3 5G supports 55W wired charging, reaching 50% charge in just 15 minutes. The OnePlus 8 Pro offers 30W wired charging (50% in 23 minutes), 30W wireless charging (50% in 30 minutes), and 3W reverse wireless charging. This makes the iQOO 3 5G the clear winner for users prioritizing quick top-ups.

Buying Guide

Buy the vivo iQOO 3 5G if you need the fastest possible wired charging and prioritize maximizing screen visibility in bright sunlight. It’s the choice for users who frequently top up their phones throughout the day and demand a responsive experience. Buy the OnePlus 8 Pro if you value wireless charging convenience, a wider range of storage/RAM configurations, and a more established software ecosystem, even if it means sacrificing some charging speed.

Frequently Asked Questions

❓ How much faster is the iQOO 3 5G's charging compared to the OnePlus 8 Pro in a full charge scenario?
While both phones reach 50% charge in a reasonable timeframe, the iQOO 3 5G's 55W charging is significantly faster overall. Based on the provided data (50% in 15 minutes), a full charge is likely achievable in under 45 minutes, compared to the OnePlus 8 Pro's estimated 60+ minutes for a full wired charge.
❓ Does the lack of wireless charging on the iQOO 3 5G significantly impact the user experience?
For users heavily reliant on wireless charging, the absence of this feature on the iQOO 3 5G is a drawback. However, the incredibly fast 55W wired charging mitigates this issue for many, as topping up the battery is quick and convenient. It depends on your charging habits.
❓ Given both phones use the Snapdragon 865, will I notice a performance difference in demanding games like PUBG?
The core performance will be very similar due to the identical chipset and CPU. However, sustained performance under heavy load may differ based on thermal management. iQOO's focus on gaming suggests they may have implemented more robust cooling, potentially leading to less throttling during extended gaming sessions.
