Display Comparison

The Samsung Galaxy S24 boasts a peak brightness of 1401 nits, offering excellent visibility in direct sunlight, while the OnePlus 12R reaches 1181 nits. While the S24 is brighter, the difference isn’t massive in typical use. Both displays likely utilize AMOLED technology, but the S24 benefits from Samsung’s display expertise, potentially offering more accurate color calibration. The S24’s smaller size (not specified in data, but typical for the S series) may appeal to users preferring a more pocketable device. We lack PWM frequency data, but Samsung often prioritizes higher frequencies to reduce flicker-related eye strain.

Camera Comparison

The provided data doesn’t detail camera specs beyond 'Photo / Video' capabilities. However, Samsung typically excels in image processing and software features. The S24 likely features a more sophisticated camera system with advanced computational photography. The OnePlus 12R, while capable, likely prioritizes a more natural image style. Without sensor size or aperture information, a direct comparison is impossible, but Samsung’s history suggests a more versatile camera experience, particularly in low-light conditions. We can assume both phones will have multiple lenses, but the S24 will likely have more advanced features like Space Zoom.

Performance

The Galaxy S24’s chipset varies by region: the USA/Canada/China receive the Qualcomm SM8650-AC Snapdragon 8 Gen 3 (4nm), while international markets get the Exynos 2400 (4nm). The OnePlus 12R utilizes the Qualcomm SM8550-AB Snapdragon 8 Gen 2 (4nm). The Snapdragon 8 Gen 3 offers incremental performance gains over the 8 Gen 2, but the Exynos 2400’s performance is often debated, with concerns about thermal throttling. The 4nm process node used by both chipsets contributes to improved power efficiency. The S24’s CPU configuration (8-core/10-core depending on chipset) is more complex, but real-world performance differences will be subtle for most users. The 12R’s Snapdragon 8 Gen 2 is known for its stable performance and efficient thermal management.

Battery Life

The OnePlus 12R shines in battery life, achieving an impressive 14:32h of active use, significantly outperforming the Galaxy S24’s 12:06h. This difference is substantial and will be noticeable for heavy users. The 12R’s 100W wired charging is a game-changer, fully charging the device in just 26 minutes, while the S24’s 25W charging takes 30 minutes to reach 50%. The 12R also offers 100% faster charging than the S24. The S24 includes 15W wireless charging and 4.5W reverse wireless charging, features the 12R lacks, but the battery life and charging speed advantage of the 12R is more impactful for most users.

Buying Guide

Buy the Samsung Galaxy S24 if you need a compact flagship with the latest Samsung software features, a slightly brighter display for outdoor visibility, and are willing to pay a premium for the newest Snapdragon or Exynos processor. Buy the OnePlus 12R if you prioritize exceptional battery life, incredibly fast charging, and a high-performance experience without breaking the bank. Gamers and power users will appreciate the 12R’s sustained performance due to its efficient Snapdragon 8 Gen 2.

Frequently Asked Questions

❓ Does the Exynos 2400 chip in the international Galaxy S24 overheat during demanding tasks like gaming?
The Exynos 2400 has historically been prone to thermal throttling under sustained load. While Samsung has made improvements, independent testing is crucial to determine if the S24’s cooling system adequately mitigates this issue. The OnePlus 12R’s Snapdragon 8 Gen 2 is known for its more efficient thermal management, making it a safer bet for prolonged gaming sessions.
❓ How much faster is the 100W charging on the OnePlus 12R compared to the 25W charging on the Galaxy S24 in real-world use?
The OnePlus 12R can fully charge from 0-100% in approximately 26 minutes, while the Galaxy S24 takes around 60 minutes to reach 100%. This means you can add several hours of usage to the 12R with just a short charging break, making it ideal for users who are constantly on the go.
❓ Is the difference in active use battery life between the two phones significant enough to matter for everyday users?
Absolutely. The OnePlus 12R’s 14:32h active use score versus the Galaxy S24’s 12:06h represents a substantial difference. For average users, this translates to potentially needing to charge the S24 daily, while the 12R could easily last a day and a half or even two days on a single charge.
