YouTube creator Android Addicts tested the battery life of all Galaxy S25 models side-by-side with last year’s Galaxy S24 Ultra, and the results are not only impressive but also a bit surprising. The Plus model with a 100mAh lower capacity managed to last longer than the Ultra model.
But first off, let’s get to the basics first. The creator tested the phones with regular tasks such as scrolling through Twitter, and Instagram, watching movies, standby, and running some benchmarks to simulate heavy workloads and gaming for about 40 minutes.
Galaxy S25 series brings a major improvement in battery life over its predecessors
The Galaxy S25, S25+, and S25 Ultra packs a 4000mAh, 4900mAh, 5000mAh battery respectively. Last year’s Galaxy S24 Ultra also has a 5000mAh battery. At the beginning of the test, all the phones were tested with Geekbench, where the S25 models scored almost the same.
It suggests Samsung isn’t taking a conservative approach towards the performance of the smaller models. And the new chip also proves its presence inside with much higher scores as compared to the S24 Ultra, so all of them will possibly continue to perform better, hence perform more calculations, during demanding tasks such as GPU benchmark going forward.
Let’s get to the results. The Galaxy S24 Ultra lasted for 8 hours and 33 minutes. The Galaxy S25 (with just 4000mAh battery) kept running until 11 hours 21 minutes through the test. However, it’s important to note that the base model dropped its brightness by quite a bit during the last 81 minutes.

Here comes the surprise: the Galaxy S25 Ultra dies before the Plus model at the 13h 02m mark, 15 minutes before the Galaxy S25 Plus. The Plus model outperforms the Ultra likely thanks to the slightly smaller display – 6.7 inches as compared to 6.9. Other aspects such as the performance, display resolution, and brightness were all very similar between the two. In summary, this is a major improvement in battery life, and it’s surprising because the capacity underneath is the same this year.
