Xiaomi 15S Pro
- Blazing-fast 90W wired charging
- Potentially higher CPU clock speeds with Xring O1
- 50W wireless charging offers quick top-ups
- Software optimization is a potential concern
- Battery life is unknown and could be a weakness
Samsung Galaxy S24 Ultra
- Exceptional battery life (13:49h active use)
- Brighter display for outdoor visibility
- Refined software experience and ecosystem
- Slower 45W wired charging
- Lower wireless charging speed (15W)
Display Comparison
The Samsung Galaxy S24 Ultra boasts a significantly brighter display, reaching a measured 1447 nits, ensuring excellent visibility even in direct sunlight. While the Xiaomi 15S Pro’s display specs are not provided, Samsung’s panel technology, likely LTPO AMOLED, dynamically adjusts refresh rates for power efficiency. The S24 Ultra’s brightness advantage is crucial for outdoor use and HDR content consumption, offering a more vibrant and immersive viewing experience.
Camera Comparison
The context data lacks detailed camera specifications for both devices, making a direct comparison challenging. However, Samsung’s Galaxy S24 Ultra is known for its versatile camera system, typically featuring a large main sensor, advanced image processing, and robust video capabilities. The Xiaomi 15S Pro’s camera performance will be a key differentiator, but without sensor size or aperture information, it’s difficult to assess its capabilities. We can assume both phones will offer multiple lenses, but Samsung’s established reputation in computational photography gives it an edge.
Performance
The Xiaomi 15S Pro’s Xring O1, built on a 3nm process, features a deca-core configuration with two high-performance Cortex-X925 cores clocked at 3.9GHz. This contrasts with the Galaxy S24 Ultra’s Snapdragon 8 Gen 3 (4nm) and its octa-core setup, led by a single Cortex-X4 core at 3.39GHz. While the Xiaomi appears to have more cores and higher clock speeds, the Snapdragon 8 Gen 3’s architectural improvements and 4nm process likely provide better sustained performance and thermal efficiency. The S24 Ultra’s LPDDR5x RAM further contributes to its responsiveness. The Xring O1’s real-world performance will depend heavily on software optimization.
Battery Life
The Samsung Galaxy S24 Ultra delivers an impressive 13:49h of active use, demonstrating excellent battery endurance. While the Xiaomi 15S Pro’s battery capacity is unknown, its 90W wired charging significantly surpasses the S24 Ultra’s 45W charging, allowing for a 65% charge in just 30 minutes. The Xiaomi also offers 50W wireless charging, compared to the Samsung’s 15W Qi wireless charging. This makes the Xiaomi ideal for users who frequently need to top up their battery quickly, even if the overall battery life isn’t as long as the S24 Ultra.
Buying Guide
Buy the Xiaomi 15S Pro if you absolutely prioritize the fastest possible charging speeds and are comfortable with a potentially less refined software experience. Its 90W wired and 50W wireless charging are unmatched in this comparison. Buy the Samsung Galaxy S24 Ultra if you value a consistently smooth experience, exceptional camera performance, and long-lasting battery life, even if it means slightly slower charging.
