How does the Galaxy S25 Ultra's battery life compare to its competitors

Battery Life Comparison

1. Galaxy S25 Ultra: Expected to leverage the new Qualcomm Snapdragon 8 Elite processor for better power efficiency. Previous models, like the S24 Ultra, achieved impressive battery life, lasting approximately 16 hours and 45 minutes in web browsing tests[2][3]. The S25 Ultra is anticipated to match or slightly improve upon this figure due to enhanced AI-driven power management features, including a rumored "Battery AI" that optimizes power consumption based on user habits[5][6].

2. OnePlus 13: This device boasts a 6,000mAh battery, significantly larger than the S25 Ultra's. The OnePlus 13 has been noted for its superior battery life in past models, and it is expected to continue this trend. The OnePlus 13 also supports faster charging speeds (up to 80W) compared to the S25 Ultra's 45W wired charging, which may give it an edge in overall usability[4][8].

3. Google Pixel 8 Pro: While specific battery capacities aren't detailed in the search results, Google's recent flagships have been competitive in battery performance. The Pixel 8 Pro is designed for efficient power use and typically offers robust battery life, although exact figures would need to be confirmed through testing.

Charging Speed

The S25 Ultra's charging capabilities remain unchanged from previous models, with 45W wired and 15W wireless charging. This is notably slower than competitors like the OnePlus 13, which charges significantly faster due to its higher wattage capabilities[4]. The lack of improvement in charging speed may be a drawback for users who prioritize quick recharging times.

Conclusion

In summary, while the Galaxy S25 Ultra maintains a solid battery capacity of 5,000mAh, its performance will largely depend on the efficiency improvements from the Snapdragon 8 Elite processor and AI features. Compared to competitors like the OnePlus 13 with its larger battery and faster charging capabilities, the S25 Ultra may face challenges in overall battery longevity and convenience. However, if Samsung's enhancements prove effective, it could still deliver competitive performance in everyday use.
