The biggest concern about the Samsung Galaxy S25 Edge was its small battery capacity. As attractive as its stylish and slim design is, its 3900 mAh battery has worried users. But now we have clear results of battery tests, which reduce this fear to a great extent.

A first look at the battery of the Samsung Galaxy S25 Edge

The Galaxy S25 Edge has only a 3900 mAh battery, while the Galaxy S25 has 4000 mAh, and the Galaxy S25 + and S25 Ultra have 4900 mAh and 5000 mAh batteries, respectively. In such a situation, the question was bound to arise whether the battery of the S25 Edge would be able to withstand a day of use or not.

Battery test report: Performance in detail

We conducted three comprehensive battery tests on the Galaxy S25 Edge: browsing, video streaming, and 3D gaming. You can see the comparison of different models in the table below:

| ——————– | ———— | ——————— | ————— | ————– | ————— |

Browsing test: Better than average

The Galaxy S25 Edge clocked 16 hours 40 minutes in the browsing test, which is above the average of 16 hours 23 minutes. While this is behind the Galaxy S25, S25+, and Ultra, it is a good sign with such a small battery.

Video streaming test: Below expected, but not bad

The Galaxy S25 Edge clocked 7 hours 44 minutes in video streaming (YouTube, etc.). This is slightly less than the Galaxy S25’s 8 hours and 1 minute, but the drop is not too severe.

Gaming test: Surprisingly good performance

The Galaxy S25 Edge scored 9 hours 38 minutes in 3D gaming, making it a solid option compared to its size. While the S25 Ultra is ahead in this, the S25 Edge also delivered a respectable result, as per its price and design.

Total screen-on time: Below average but acceptable

The estimated total screen time of the Galaxy S25 Edge is 6 hours 22 minutes, which ranks #87 among phones tested in the last 2 years. The average screen time is 7 hours 4 minutes. This is less than the 7 hours of the Galaxy S25 and the 8 hours of the Ultra, but the difference is not very big.

Better position compared to other popular phones

Interestingly, the S25 Edge beats several popular mid-range phones:

iPhone 16e (screen time: 6 hours 4 minutes)

Galaxy A35 (screen time: 6 hours 12 minutes)

Galaxy S24 FE (screen time: 6 hours 20 minutes)

Samsung has done a good job in battery optimization despite the low battery capacity.

Charging speed: The disappointing side

The charging speed of the Galaxy S25 Edge is just 25W. There is no charger provided by the company in the box, and wireless charging support is also not confirmed.

Charge in 30 minutes: Not available

Time to full charge: Not available

This is where Samsung needs to improve, as other brands are now offering fast charging up to 67W and 120W.

Design vs battery: A question of balance
