The Samsung Galaxy S23 Ultra gets first place in autonomy in the Ultra-Premium segment of DXOMark

The battery of the Samsung Galaxy S23 Ultra has obtained an excellent overall score in the DXOMark test, ranking first in the Ultra-Premium segment. Powered by Qualcomm’s Snapdragon chipset, the Galaxy S23 Ultra vastly outperformed its predecessor, the Samsung Galaxy S22 Ultra (in both Snapdragon and Exynos versions), thanks to better battery life and efficiency scores. The Samsung Galaxy S23 Ultra achieved excellent results in autonomy tests. The battery lasted almost 67 hours with moderate use, with less than a 2% loss per night on average. In outdoor tests, performance was also very good, except when using the camera, where battery life was slightly below average. During the tests in which particular uses are evaluated separately, the autonomy was also excellent, especially when streaming videos. However, the battery level plummeted at 5%, which could affect the user experience. The Galaxy S23 Ultra’s charging results were average, both wired and wireless. The time to fully replenish the battery with a wired charger was 1 hour and 21 minutes, and with a wireless one, 2 hours and 18 minutes.

A quick 5-minute wired charge provided a good average of 5 hours and 23 minutes of autonomy, but the range recovered from charging from 60% was only half of that recovered from charging from 20%. Residual consumption for both wired and wireless chargers was very low when the device is fully charged and still plugged in. In almost all test cases (except music streaming and inactivity with screen off), currents Download rates were very low, which means that the device is well optimized. Flagship devices often face battery performance challenges due to their new power-hungry features. This is where careful hardware and software integration plays an important role in battery performance. Compared to other devices in the Ultra-Premium segment ($800+), the Samsung Galaxy S23 Ultra easily achieved full marks. Although it did not set new highs in the subscores, its excellent autonomy and efficiency, combined with a good charging experience, allowed the Galaxy S23 Ultra to obtain the best score to date for this segment.
