How does the battery life of the S24 Ultra compare to other flagship smartphones

Battery Capacity and Performance

- Samsung Galaxy S24 Ultra: Equipped with a 5000mAh battery, it can last up to 56 hours under moderate usage. Reports indicate that it performs well during activities like streaming and gaming, but its autonomy can decline in typical usage scenarios[1][2].

- Apple iPhone 15 Pro Max: With a smaller 4441mAh battery, it surprisingly offers up to 10 hours and 24 minutes of screen-on time in tests, showcasing excellent efficiency despite its lower capacity[7].

- OnePlus 12: This model features a 5400mAh battery and is noted for strong performance, achieving around 9 hours and 45 minutes of screen-on time[7].

- Xiaomi 14 Ultra: Also with a 5000mAh battery, it has been reported to achieve over 11 hours of screen-on time, leveraging advanced battery technology[7].

- Vivo X100 Pro: Similar to the S24 Ultra with a 5400mAh battery, it offers competitive performance, though specific screen-on time metrics were not detailed in the sources[7].

Efficiency Ratings

The S24 Ultra has an efficiency rating of 1.5 out of 5, indicating moderate energy management compared to its hardware capabilities. In contrast, the iPhone 15 Pro Max, despite its smaller battery, excels in efficiency, which contributes to its impressive screen-on time[1][2].

Charging Capabilities

- The S24 Ultra supports 45W fast charging, taking about 1 hour and 27 minutes for a full charge, which is average among flagship devices. However, its quick charge capabilities are less effective, providing only about 4 hours and 22 minutes of additional autonomy from a 5-minute charge[2][3].

Conclusion

In summary, while the Samsung Galaxy S24 Ultra offers solid battery life and performance, it faces stiff competition from other flagship devices, particularly in terms of efficiency and screen-on time. Users looking for the longest-lasting battery may find alternatives like the iPhone 15 Pro Max or Xiaomi 14 Ultra more appealing, especially for heavy usage scenarios.
