Galaxy S21 Ultra 5G • Unlocked vs OnePlus 10 Pro • Unlocked

The Samsung Galaxy S21 Ultra 5G, released in January 2021, and the OnePlus 10 Pro, launched globally in March 2022, are both high-end Android smartphones designed to offer premium experiences. While both devices feature advanced displays and powerful internals, they differentiate themselves through their camera philosophies, software approaches, and overall design. The Galaxy S21 Ultra emphasizes a comprehensive camera system and S Pen support, while the OnePlus 10 Pro focuses on rapid charging and a refined user interface.

When considering the long-term usability of these devices, several factors come into play, including software support and physical resilience.

• Software Longevity: The Samsung Galaxy S21 Ultra 5G, being a Samsung flagship, typically receives four years of Android operating system updates and five years of security updates from its release date. This provides a longer period of official software support compared to the OnePlus 10 Pro, which generally offers three major OS updates and four years of security updates. Users prioritizing extended software support will find the S21 Ultra more aligned with their needs.
• Physical Durability: The Galaxy S21 Ultra features Corning Gorilla Glass Victus on both its front and back, offering enhanced scratch and drop resistance. It also carries an IP68 rating for dust and water resistance. The OnePlus 10 Pro also uses Gorilla Glass for screen protection. However, early durability tests for the OnePlus 10 Pro indicated a potential structural weakness, with some units reportedly snapping in half under significant bending pressure, particularly around the camera module.
• Repairability: Both devices present challenges for repair, often requiring specialized tools and expertise to access internal components. The OnePlus 10 Pro has been noted to have an average repairability score, with some components like the battery and screen being accessible, but the use of adhesive and plastic covers can complicate the process.

Both smartphones are equipped with high-performance processors designed to handle demanding applications and multitasking with ease, though their approaches to power management and storage differ.

• Processing Power: The Galaxy S21 Ultra 5G and the OnePlus 10 Pro both deliver smooth performance for everyday tasks, intensive gaming, and heavy multitasking. Applications launch quickly, and transitions between apps are fluid. The OnePlus 10 Pro, being released later, incorporates a slightly newer generation of processing technology, which can translate to marginal improvements in raw speed and efficiency for the most demanding workloads.
• Battery Performance: Both devices house a 5000 mAh battery. The Galaxy S21 Ultra 5G generally provides a full day of use for most users, with some reports indicating over 11 hours of screen-on time under specific conditions. The OnePlus 10 Pro also offers strong battery life, with users reporting similar endurance, often lasting through a full day with moderate to heavy usage. The OnePlus 10 Pro stands out with its exceptionally fast wired charging capabilities, allowing for a rapid recharge.
• Storage and RAM: The Galaxy S21 Ultra 5G was available with up to 16GB of RAM and 512GB of internal storage, providing ample space and memory for power users. The OnePlus 10 Pro typically comes with 8GB or 12GB of RAM and up to 256GB of storage, which is sufficient for most users but offers fewer high-end configurations.

The visual experience on both devices is characterized by large, vibrant displays, though with some distinctions in technology and features.

• Display Technology and Size: The Galaxy S21 Ultra 5G features a 6.8-inch Dynamic AMOLED 2X display, while the OnePlus 10 Pro has a 6.7-inch Fluid AMOLED LTPO 2.0 display. Both offer QHD+ resolutions (3200x1440 for S21 Ultra, 3216x1440 for OP10 Pro), resulting in sharp and detailed visuals.
• Refresh Rate and Smoothness: Both phones boast adaptive 120Hz refresh rates, which dynamically adjust based on content to provide smooth scrolling and animations while conserving battery life. The OnePlus 10 Pro's LTPO 2.0 technology allows its refresh rate to scale down to 1Hz for static content, potentially offering greater power efficiency.
• Brightness and Clarity: The Galaxy S21 Ultra 5G can reach a peak brightness of 1500 nits, making it exceptionally bright and easy to view even in direct sunlight. The OnePlus 10 Pro also offers a bright display, with a peak brightness of around 1300 nits, ensuring good visibility outdoors. Both displays offer excellent color accuracy and contrast, providing an immersive viewing experience for media consumption.

Both smartphones offer versatile camera systems, but they cater to slightly different photographic preferences and capabilities.

• Rear Camera Systems: The Galaxy S21 Ultra 5G features a quad-camera setup, including a 108MP main sensor, a 12MP ultrawide, and two 10MP telephoto lenses (3x and 10x optical zoom), providing extensive zoom capabilities. The OnePlus 10 Pro comes with a triple camera system co-developed with Hasselblad, featuring a 48MP main sensor, a 50MP ultrawide lens with a wide 150-degree field of view option, and an 8MP telephoto lens with 3.3x optical zoom.
• Photography Performance: The S21 Ultra is known for its detailed images, especially with its advanced zoom features, and generally consistent color science across lenses. The OnePlus 10 Pro's main camera delivers crisp photos with accurate exposure and good colors, particularly benefiting from Hasselblad's color science. Its ultrawide camera offers a unique perspective, though some users note it may not always match the detail of the main sensor.
• Video Recording: Both devices are capable of recording high-resolution video, including 8K at 24 or 30 frames per second and 4K at various frame rates. The S21 Ultra offers robust video stabilization and features. The OnePlus 10 Pro also provides solid video performance, with features like Movie Mode for manual controls and dual-view video.
• Front Camera: The S21 Ultra has a high-resolution 40MP front camera, while the OnePlus 10 Pro features a 32MP front camera, both capable of capturing detailed selfies and clear video calls.
