Oppo Reno6 Pro 5G

  • Significantly faster 65W charging
  • Potentially better thermal management due to 6nm Dimensity 1200
  • Often available at a lower price point

  • Display likely not as bright as the S21+
  • Camera system may not be as refined as Samsung's

Samsung Galaxy S21+ 5G

  • Brighter display for outdoor visibility
  • Established Samsung camera ecosystem
  • Wireless and reverse wireless charging

  • Slower 25W charging
  • Potential for thermal throttling with Snapdragon 888/Exynos 2100
  • Generally more expensive

Display Comparison

The Samsung Galaxy S21+ boasts a brighter display, peaking at 883 nits measured, offering superior visibility in direct sunlight. While the Reno6 Pro 5G’s display specs aren’t explicitly stated, it’s likely to be slightly dimmer. Both feature infinite (nominal) contrast ratios, typical of OLED panels. However, the S21+’s panel is likely to have a higher refresh rate, contributing to smoother scrolling and animations. The S21+’s display is a key advantage for outdoor use and media consumption.

Camera Comparison

Both devices offer capable camera systems, but details beyond 'Photo/Video' are limited. The S21+ likely benefits from Samsung’s established image processing algorithms and potentially larger sensor sizes. The Reno6 Pro 5G’s camera performance will depend heavily on its sensor and lens choices, which aren’t specified. It’s reasonable to assume the S21+ has a more refined and versatile camera experience, particularly in low-light conditions, given Samsung’s history. The inclusion of OIS (Optical Image Stabilization) is expected on both, but the effectiveness will vary based on implementation.

Performance

The core of the performance difference lies in the chipsets. The Samsung Galaxy S21+ utilizes either the Exynos 2100 (international) or the Qualcomm Snapdragon 888 (USA/China), both fabricated on a 5nm process. The Oppo Reno6 Pro 5G employs the Mediatek Dimensity 1200, built on a 6nm process. While the Snapdragon 888 and Exynos 2100 have a slight theoretical CPU advantage with their Cortex-X1 cores (2.9/2.84 GHz vs 3.0 GHz on the Reno6 Pro’s Cortex-A78), the Dimensity 1200’s architecture, with its three Cortex-A78 cores, provides strong multi-core performance. Critically, the 6nm process of the Dimensity 1200 generally translates to better thermal efficiency, potentially reducing throttling during sustained workloads compared to the 5nm chips in the S21+. Both phones feature ample RAM, likely LPDDR5, ensuring smooth multitasking.

Battery Life

The Samsung Galaxy S21+ achieves an endurance rating of 114 hours, indicating solid battery life. However, the Reno6 Pro 5G’s charging speed is a game-changer. With 65W wired charging, it can replenish the battery from 0-100% significantly faster than the S21+'s 25W charging (and its additional 15W wireless and 4.5W reverse wireless options). While the S21+’s battery capacity isn’t specified, the Reno6 Pro’s faster charging mitigates any potential capacity disadvantage. This means less downtime and more time using the phone.

Buying Guide

Buy the Oppo Reno6 Pro 5G if you prioritize blazing-fast charging, a smooth user experience for everyday tasks, and excellent value for your money. Buy the Samsung Galaxy S21+ 5G if you absolutely require the brightest possible display, prefer the Samsung ecosystem, or find a significantly discounted price that outweighs the charging and thermal advantages of the Oppo.

Frequently Asked Questions

❓ Does the Exynos 2100 in the international S21+ 5G overheat during extended gaming sessions?
The Exynos 2100 has been known to exhibit thermal throttling under sustained load, particularly during demanding games. While Samsung implemented software optimizations, the Dimensity 1200 in the Reno6 Pro 5G, built on a 6nm process, generally offers better thermal efficiency, potentially leading to more consistent performance during long gaming sessions.
❓ Is the 65W SuperVOOC charging on the Reno6 Pro 5G compatible with Power Delivery (PD) chargers?
While Oppo's SuperVOOC charging is proprietary, it is generally compatible with PD chargers, but you won't achieve the full 65W speeds unless you use the included Oppo charger. Using a standard PD charger will still provide faster charging than the S21+'s 25W, but not at the maximum rate.
❓ How does the image processing differ between the Reno6 Pro 5G and the Galaxy S21+ 5G?
Samsung's image processing tends to produce vibrant, saturated colors, while Oppo often aims for a more natural look. The S21+ also benefits from Samsung's scene optimizer, which automatically adjusts settings based on the detected scene. The Reno6 Pro 5G's image processing style will likely be more subtle, prioritizing accuracy over punchy visuals.
❓ Does the Reno6 Pro 5G support 90fps gaming in popular titles like PUBG Mobile?
The Dimensity 1200 is capable of handling 90fps gaming in PUBG Mobile, but achieving this frame rate will depend on the game settings and the phone's thermal conditions. The Reno6 Pro 5G's efficient cooling system should help maintain stable frame rates for extended periods.
