“Samsung Galaxy S25 Edge Battery Anxiety – Real User Experience”

We were astounded by the Samsung Galaxy S25 Edge’s incredibly small frame when we first held it. But as soon as we noticed the phone’s 3,900mAh battery, our awe swiftly gave way to worry. It’s not little, but for a flagship smartphone in 2025—especially one as large and tall as the Galaxy S25 Plus—that’s a quite conservative cell. Even the small Galaxy S25 slightly outperforms the Edge with 4,000mAh, while the S25 Plus boasts a large 4,900mAh capacity. However, it’s also important to keep in mind that the Edge has a larger display with a better QHD resolution and a more demanding 200MP camera, both of which may use more battery than the standard S25.

According to Samsung, the Edge’s battery life should fall between that of the Galaxy S24 and S25, although our testing has shown that this is a bit optimistic. Let’s examine the outcomes of our automated battery longevity tests, which were all carried out at a constant 300 nit display brightness. We also examined the S24’s two variants, the S25, and the S25 Plus for comparison.

Regretfully, the Galaxy S25 Edge performs poorly overall. With the exception of our Zoom call test, where it outperforms the Snapdragon version of the Galaxy S24, it performs worse than the Galaxy S24 series in most categories and clocks fewer minutes than the Galaxy S25 in every test. In the Zoom and 4K recording tests, it likewise performs similarly to the Exynos model. All phones performed equally in the camera capture time, which was the only consistent outcome. If not, there is a noticeable performance difference that is considerably outside the error margin. It is obvious that the Edge’s battery life is shorter than that of its siblings.

As the seemingly insignificant 100mAh difference with the small Galaxy S25 would imply, the Edge’s actual battery life is much poorer. I estimate that, on average, the Zoom call duration is 27% worse and the video recording and playback longevity is about 20% shorter than with the standard S25. Although web browsing did somewhat better, declining by just approximately 8%, it is still poorer than one might anticipate given the battery size.

The Edge’s beefier specs drain the 3,900mAh battery even faster than the S25.

The Edge’s bigger, sharper display definitely uses more power than the standard S25, while software optimization might be a factor. This, along with the lower battery, will result in a screen-on time that is disappointing.

Let’s put the similarities aside for a moment and concentrate on screen time. Our testing show that the Galaxy S25 Edge enables up to 17 hours of offline 4K movie playback, seven to eight hours of moderate use (such as web browsing and video calls), and approximately four and a half hours of continuous content capture. While these numbers aren’t bad on their own, they lag behind their siblings by an hour or two. Additionally, bear in mind that this is under perfect, unconventional circumstances. Things rapidly deteriorate when you add games, background tasks, or excessive data usage.

Cutting it fine is an understatement, there’s no headroom for aging battery health here.

It is evident that Samsung constructed the Edge with a battery capacity that allows for a full day of operation. Even while the Galaxy S25 Edge might handle light use now, think about how it will function in two or three years, especially given its $1,100 price tag. After two years, even a slight loss to 90% of its initial battery capacity could be problematic; a dip to 80% will have you grabbing a charger before the day is even over.

Furthermore, we observed that the thin metal frame heated up a lot when being used, which can lead to inefficient discharge and increased self-discharge in addition to hastening battery deterioration. This may help to explain why Samsung has once again resorted to slow 25W charging and why the phone appears to perform especially poorly in demanding testing, such as our Zoom call.

In any event, we now have the facts to support the prediction that the Galaxy S25 Edge would have battery issues. You might want to avoid Samsung’s incredibly slim flagship if you intend to keep your next phone for a few years.
