Early Samsung Galaxy S25 Edge hands-on tests indicate battery and performance parity with the Galaxy S25+

Samsung's new Galaxy S25 Edge launched this week to mixed reactions. While the flagship phone pushes the limits of how thin a smartphone can be—thanks to its 5.8 mm thickness—concerns have risen about its lack of a telephoto camera, and relatively small 3,900 mAh battery. It appears, however, that the latter may not be as problematic as initially assumed.

As shown in a hands-on video by Korean channel Amazing ddongcan, the new Galaxy S25 Edge keeps up with the Galaxy S25+ in battery performance, regardless of the significant difference in battery capacities.  While the S25+ has a 4,900 mAh battery versus the S25 Edge's 3,900 mAh unit, the thinner phone trails by just 2% after 3h20m of testing, and 5% after 7h22m.

The Galaxy S25+ does outperform the S25 Edge in benchmark tests, however—albeit not by much. On Geekbench 6, the S25+ records a single-core and multi-core score of 3,095 and 9,753 respectively. The S25 Edge scores 2,889 and 9,282 on those two tests, indicating a slight ~5% advantage for the S25+ (buy on Amazon).

Those numbers carry over to 3DMark's WildLife stress test, where the S25+ is shown with a best loop score of 20,049, versus the S25 Edge's 18,138. The S25+ also showcased better stability (50.5%), compared to the S25 Edge (45.6%).

It's worth pointing out that the benchmark performance differences between the two phones are minor enough to be chalked up to software optimization, with the S25 Edge likely still running on an early build. As for the battery test, it must be noted that both phones were running entirely on Wi-Fi and in airplane mode.
