- Exynos variant may exhibit thermal throttling
Display Comparison
The Samsung Galaxy S24+ boasts a peak brightness of 1452 nits, ensuring excellent visibility even in direct sunlight. While the K80 Ultra’s display specs are not provided, Samsung’s panel technology is known for its color accuracy and vibrancy. The S24+ likely utilizes LTPO technology for adaptive refresh rates, contributing to improved battery efficiency. The absence of detailed display information for the K80 Ultra makes a direct comparison difficult, but Samsung’s established display prowess gives it an edge.
Camera Comparison
The context data provides limited camera details for both devices. However, Samsung’s Galaxy S24+ is expected to deliver a more consistent and refined camera experience, leveraging its advanced image processing algorithms and likely a larger main sensor. The K80 Ultra’s camera performance is an unknown quantity, and the absence of sensor size information makes it difficult to assess its capabilities. We can assume the S24+ will excel in both photo and video capture, offering features like advanced stabilization and computational photography. The K80 Ultra will likely rely more on hardware capabilities, and its image processing may not be as sophisticated.
Performance
The core battle lies in the chipsets. The Xiaomi K80 Ultra’s Mediatek Dimensity 9400+ (3nm) features a unique CPU configuration with a Cortex-X925 prime core clocked at 3.63 GHz, suggesting a focus on single-core performance. The Samsung Galaxy S24+ utilizes the Qualcomm Snapdragon 8 Gen 3 (4nm) in the US/Canada/China, and the Exynos 2400 (4nm) internationally. While both are 4nm chips, the Dimensity 9400+'s 3nm process *should* offer better power efficiency. However, the Snapdragon 8 Gen 3 is renowned for its optimized GPU performance and thermal management. The Exynos 2400’s performance is more variable, with some reports of throttling under sustained load. The K80 Ultra’s LPDDR5x RAM is standard for this class, and the Snapdragon 8 Gen 3 also supports LPDDR5x. The K80 Ultra’s CPU architecture, with its X925 core, is geared towards raw speed, while the S24+'s Snapdragon prioritizes sustained performance.
Battery Life
The Samsung Galaxy S24+ achieves a 12:30 hour active use score, demonstrating solid battery life. It supports 45W wired charging, reaching 65% in 30 minutes, alongside 15W wireless and 4.5W reverse wireless charging. The Xiaomi Redmi K80 Ultra, however, boasts a significantly faster 100W wired charging, likely achieving a full charge in under 40 minutes. While the K80 Ultra’s battery capacity is unknown, the faster charging speed is a major advantage for users who prioritize quick top-ups. The S24+'s wireless charging and reverse wireless charging capabilities offer added convenience.
Buying Guide
Buy the Xiaomi Redmi K80 Ultra if you need uncompromising CPU performance for demanding tasks like gaming and video editing, and value incredibly fast charging above all else. Buy the Samsung Galaxy S24+ if you prefer a more refined and consistent user experience, a versatile camera system, and the peace of mind that comes with Samsung’s software support and ecosystem integration.
