Flagship smartphones should provide the user with everything they need, including long battery life. This is still one of the key user requests. And although the models of the last two years have significant improvements, battery life still remains an important factor when comparing devices from different manufacturers.

Youtube channel PhoneBuff tested not only durability of Samsung Galaxy S23 Ultra and iPhone 14 Pro Max, but also compared the battery life of these devices. This test involved several common smartphone usage scenarios, such as calling, messaging, streaming music, watching videos, playing games, waiting, etc.

All testing is automated and should simulate the same conditions for both devices.

Despite the fact that the Samsung Galaxy S23 Ultra significantly outperformed last year’s model, this time it still lost to the iPhone 14 Pro Max. However, this year, during the tests, the leadership in the percentage of remaining battery charge changed between smartphones a couple of times.

The Samsung Galaxy S23 Ultra was the first to turn off, when the iPhone 14 Pro Max still had 6% battery left. The final runtime was 27 hours 6 minutes for the S23 Ultra, and 27 hours 44 minutes for the 14 Pro Max. Taking into account the fact that each of the smartphones was given 16 hours of “rest” during the test, the time of active work for them was 11 hours 6 minutes and 11 hours 44 minutes, respectively.

The final difference, against the background of the entire duration of the test, is subjectively not very fundamental. Moreover, in each individual case, these models can also surpass each other in battery life, which will depend only on the tasks that the user will set for the device. But in simulated circumstances, the iPhone still holds the lead in this competition.
