Oppo Reno3 Pro 5G

  • More affordable price point
  • Excellent battery endurance (100h)
  • Sleek and lightweight design (based on brand reputation)

  • Less powerful Snapdragon 765G chipset
  • Likely inferior camera performance
  • Missing wireless charging

OnePlus 8 Pro

  • Flagship Snapdragon 865 performance
  • 30W wired and wireless charging with reverse wireless
  • Likely superior camera system

  • Potential for thermal throttling under heavy load

Display Comparison

Both the Oppo Reno3 Pro 5G and OnePlus 8 Pro feature displays with an 'Infinite' (nominal) contrast ratio, suggesting excellent black levels. However, the Reno3 Pro 5G reaches a measured peak brightness of 819 nits, while the OnePlus 8 Pro’s brightness is not specified. This suggests the OnePlus 8 Pro likely offers superior visibility in direct sunlight. While both are likely high-refresh-rate displays (based on brand history), the OnePlus 8 Pro is confirmed to have a 120Hz panel, offering smoother scrolling and animations. The OnePlus 8 Pro’s display is also likely to benefit from more advanced color calibration and potentially LTPO technology for variable refresh rate, improving efficiency.

Camera Comparison

Both phones offer photo and video capabilities, but details are limited. The OnePlus 8 Pro, given its flagship positioning, likely features a more sophisticated camera system with larger sensors and more advanced image processing. While specific sensor sizes aren’t provided, the OnePlus 8 Pro’s price point suggests a higher-quality main sensor and potentially a more versatile ultrawide lens. The Reno3 Pro 5G likely focuses on delivering good image quality in various conditions, but may lack the advanced features and low-light performance of the OnePlus 8 Pro. The absence of details regarding OIS (Optical Image Stabilization) on either device makes a direct comparison difficult, but it’s a feature more commonly found on flagship models like the OnePlus 8 Pro.

Performance

The core difference lies in the chipsets. The Oppo Reno3 Pro 5G utilizes the Qualcomm Snapdragon 765G (7nm), featuring an octa-core CPU with a 2.4 GHz Kryo 475 Prime core. The OnePlus 8 Pro, however, boasts the significantly more powerful Snapdragon 865 5G (7nm+). Its CPU configuration – a 2.84 GHz Cortex-A77 prime core and three additional Cortex-A77 cores – delivers substantially higher single-core and multi-core performance. This translates to faster app loading times, smoother multitasking, and a better gaming experience. The 7nm+ node of the Snapdragon 865 also offers improved thermal efficiency, potentially mitigating throttling during sustained workloads. The OnePlus 8 Pro’s availability with up to 12GB of RAM (vs. unspecified for the Reno3 Pro) further enhances multitasking capabilities.

Battery Life

Both devices achieve an endurance rating of approximately 100-103 hours, indicating comparable battery life. However, the OnePlus 8 Pro offers a more versatile charging solution. Both support 30W wired charging, achieving 50% charge in roughly 20-23 minutes. The OnePlus 8 Pro adds 30W wireless charging (50% in 30 minutes) and 3W reverse wireless charging, providing greater convenience and the ability to charge accessories. While the battery capacity isn’t specified for either device, the OnePlus 8 Pro’s faster wireless charging and reverse wireless capabilities provide a clear advantage for users who value these features.

Buying Guide

Buy the Oppo Reno3 Pro 5G if you need a sleek, 5G-capable phone with excellent battery endurance and are willing to trade some processing power for a lower price. It’s ideal for everyday tasks, social media, and casual gaming. Buy the OnePlus 8 Pro if you prioritize uncompromising performance for demanding games, intensive multitasking, and benefit from faster charging speeds (wired and wireless) and the added convenience of reverse wireless charging. It’s the choice for power users and mobile gamers.

Frequently Asked Questions

❓ Does the Snapdragon 865 in the OnePlus 8 Pro experience significant thermal throttling during extended gaming sessions?
While the Snapdragon 865 is a powerful chip, it can be prone to thermal throttling under sustained heavy load. The OnePlus 8 Pro incorporates cooling solutions, but prolonged gaming at maximum settings may still result in reduced performance over time. However, the 7nm+ node is more efficient than previous generations, mitigating this issue to some extent.
❓ Is the 30W wireless charging on the OnePlus 8 Pro significantly faster than traditional wireless charging?
Yes, 30W wireless charging is considerably faster than standard Qi wireless charging (typically 5-15W). It allows the OnePlus 8 Pro to reach 50% charge in approximately 30 minutes, making it a viable alternative to wired charging for many users. However, it still won't be as fast as the 30W wired charging.
❓ How does the Snapdragon 765G in the Oppo Reno3 Pro 5G handle demanding games like PUBG or Call of Duty: Mobile?
The Snapdragon 765G is capable of running popular games like PUBG and Call of Duty: Mobile, but you may need to lower graphics settings to achieve consistently smooth frame rates. It won't deliver the same level of performance as the Snapdragon 865, but it's still a capable gaming platform for casual and moderate gamers.
