OnePlus 13
- Incredibly fast 100W charging
- Superior battery endurance (61:36h)
- Competitive Snapdragon 8 Elite performance
- Lower battery cycle count (1000)
- Slightly dimmer display compared to S25 Ultra
Samsung Galaxy S25 Ultra
- Brighter display (1417 nits)
- Exceptional battery cycle life (2000)
- Potentially better thermal management
- Slower charging speed (45W)
- Lower battery endurance (44:54h)
Display Comparison
The Samsung Galaxy S25 Ultra boasts a significantly brighter display, reaching 1417 nits compared to the OnePlus 13’s 1204 nits. This difference is immediately noticeable in direct sunlight. Both utilize advanced panel technology, likely LTPO AMOLED for adaptive refresh rates, but Samsung’s higher peak brightness provides a more vivid outdoor viewing experience. While both will likely offer excellent color accuracy, the S25 Ultra’s brightness advantage is a clear win for outdoor visibility.
Camera Comparison
While detailed camera specs are missing, the focus should be on image processing and sensor size. Given Samsung’s history, the S25 Ultra will likely prioritize vibrant, saturated colors, while OnePlus tends towards a more natural look. The larger sensor on the S25 Ultra (assuming it follows Samsung’s trend) will excel in low-light conditions, capturing more detail and reducing noise. Ignoring the likely inclusion of low-resolution macro lenses on both devices, the primary sensor and its associated OIS system will be the defining factor in image quality.
Performance
Both devices are powered by the Qualcomm SM8750-AB/AC Snapdragon 8 Elite (3nm), featuring the same Octa-core CPU configuration with 2x Oryon V2 Phoenix L cores at slightly different clock speeds (4.32 GHz vs 4.47 GHz). The S25 Ultra’s marginally higher CPU clock speed may translate to a small performance edge in synthetic benchmarks, but real-world differences will likely be negligible. The key differentiator will be thermal management; Samsung’s larger chassis may allow for more effective heat dissipation, potentially preventing throttling during sustained workloads. Both utilize LPDDR5x RAM, ensuring fast memory access.
Battery Life
The OnePlus 13 delivers a remarkable 61:36h endurance score, significantly exceeding the S25 Ultra’s 44:54h. This is coupled with an impressive 100W wired charging, capable of reaching 50% charge in just 13 minutes and a full charge in 36 minutes. The S25 Ultra, while offering 2000 battery cycles compared to the OnePlus 13’s 1000, charges much slower at 45W, taking 30 minutes to reach 65% charge. The OnePlus 13’s faster charging is a game-changer for users who need a quick power boost, while the S25 Ultra prioritizes long-term battery health and longevity.
Buying Guide
Buy the OnePlus 13 if you need a phone that can easily last a full day with heavy use and recharge from 0-100% in under an hour. It’s ideal for users who frequently travel or dislike battery anxiety. Buy the Samsung Galaxy S25 Ultra if you prioritize a brighter, more vibrant display, and value long-term battery health with its 2000 charge cycles, even if it means slower charging speeds and slightly less overall endurance.
