Samsung Galaxy S25 edge battery life is as bad as you think

When we first picked up Samsung Galaxy S25 EdgeWe wondered about the delicate thin frame. However, our wonder quickly turned to concern when we saw the phone’s 3 900 mAh battery capacity. It is not small but it is a fairly conservative cell for a flagship smartphone in 2025, especially such a tall and wide as Galaxy S25 Plus.

In comparison, the S25 Plus houses a significant 4,900 mAh cell, while even the compact galaxy S25 nudges in front of the edge with 4,000 mAh. But it is also worth noting that the edge has a larger screen with higher QHD resolution and a more demanding 200MP camera -factors that all can attract more power than those in the regular S25.

Samsung even claims that the edge should have battery life Somewhere between Galaxy S24 and S25, but our testing has found that this is quite optimistic. Let’s look at the results of our automated battery’s lifetime tests, all done with a smooth display of brightness of 300 nits. In comparison, we also tested both models of S24, as well as S25 and S25 Plus.

Unfortunately, the Galaxy S25 edge underperforms the entire line. It watches fewer minutes than the Galaxy S25 in each test and does worse than the Galaxy S24 series in most categories -except for our Zoom Call test, beating the Snapdragon version of the Galaxy S24. It also corresponds to the Exynos model in the 4K recording and zoom tests. The only consistent result everywhere is in camera time, where all phones performed in the same way. Otherwise, the performance gap is considerably and well outside the margin of error. The battery life of the edge is clearly inferior to the siblings.

In fact, the real battery life of the edges is far worse than the seemingly smaller 100 mAh difference with the compact galaxy S25 suggests. On average, I calculate a 20% reduction in video recording and the life of the playback compared to the regular S25, and 27% poorer performance in the Zoom Call duration. Browsing did a little better, with only about 8% decline, but it is still worse than the battery size will cause you to expect.

Software optimization can play a role, but the edges of the edges are undoubtedly more power than the usual S25. Combined with the smaller battery, this is a recipe for disappointing screen-at-time.

Put the comparisons to a moment, let’s focus on the Screen-On era itself. Based on our tests, the Galaxy S25 Edge delivers about four and a little hours of constant content, seven to eight hours of moderate use (such as browsing and video calls), and up to 17 hours offline 4K video playback. These numbers are not terribly isolated, but fall one hour or two behind the siblings. And remember that this is under ideal conditions outside the box. Add background tasks, powerful data usage or games, and things worsen rapidly.

Samsung has built the edge with a battery capacity that clearly cuts it very nice for a whole day of use. While the Galaxy S25 Edge can handle modest use today, you can consider how it will work after two or three years, especially at a price point of $ 1100. A modest decline to 90% of its original battery capacity after two years could already spell problems; A fall to 80% will make you reach a charger before the day is over.

In addition, we noticed the thin metal frame often heated during use, which not only accelerates the battery breakdown, but also can cause the battery to emit ineffective and increase self -emission. This may explain why the phone seems to perform particularly poorly in demanding tests, such as our zoom cry, and why Samsung has adhered to slow 25w charging again.

Either way, it didn’t take a crystal ball to predict battery problems with the Galaxy S25 edge, but now we have the data to prove it. If you are planning to store your next phone for a few years, you may want to steer clear of Samsung’s ultra-thin flagship.
