The Samsung Galaxy S25 Ultra and the Google Pixel 9 Pro XL both feature impressive battery capacities, but they differ in performance and charging capabilities.
Battery Capacity and Longevity
- Both devices are equipped with batteries close in capacity: the S25 Ultra has a 5,000mAh battery, while the Pixel 9 Pro XL has a slightly larger 5,060mAh battery[2][6].- In practical usage tests, the S25 Ultra demonstrated a battery life of seven hours and five minutes during a demanding battery drain test, which involved various apps and video playback[1]. This performance places it just behind competitors like the OnePlus 13, which lasted longer in similar tests.
- The Pixel 9 Pro XL is reported to perform admirably as well, lasting throughout a full day even under heavy usage, although specific test durations were not detailed in the sources[4][8].
Charging Speeds
- The S25 Ultra supports 45W wired charging, allowing it to charge from 0% to approximately 70% in 30 minutes, and reaching full charge in about 57 minutes[1][4]. This is a significant improvement over its predecessor.- In contrast, the Pixel 9 Pro XL offers 37W wired charging but excels in wireless charging with speeds of 23W, compared to the S25 Ultra's 15W wireless charging[2][6].
Conclusion
While both phones provide solid battery performance for daily use, the Galaxy S25 Ultra may have an edge in wired charging speed. However, the Pixel 9 Pro XL's slightly larger battery capacity and superior wireless charging capabilities could make it more appealing for users who prioritize those features. Overall, both devices are designed to last through a typical day of usage without issues.Citations:
