Battery performance: between guess and reality
The battery performance of the Galaxy S25 Edge is slightly below average, but not as bad as initially thought. In the battery tests we have carried out, this phone has produced some commendable figures, especially considering its size and design.
Browsing performance
In the browsing test, in which webpages are loaded via an automated script, the S25 Edge performed for 16 hours and 40 minutes. This figure is better than the average (16h 19m) and gives users confidence that this phone will provide enough backup for normal browsing.
YouTube video streaming test
In the video test, specifically while streaming on YouTube at 1080p quality, the S25 Edge recorded a figure of 7 hours 44 minutes. While this is slightly less than the Galaxy S25 (8h 1m), the difference is not so big that it is considered a deal breaker.
Gaming test: Average backup under heavy usage
In the 3D gaming test, the Galaxy S25 Edge provided a backup of up to 9 hours 38 minutes. This is definitely behind the Galaxy S25 Ultra, but much better than most mid-range and older flagships. This is good news for users who like to play games on smartphones.
Comparison with other devices
The Galaxy S25 Edge ranks 86th in terms of its total screen-on time (6h 22m) among phones tested in the last two years. While it is not in the top 50, it is not at the bottom end of the list either.
Interestingly, the S25 Edge beats some popular mid-range devices:
iPhone 16e: 6h 4m
Galaxy A35: 6h 12m
Galaxy S24 FE: 6h 20m
This comparison clearly shows that the battery life of the Galaxy S25 Edge is slightly below average, but it is by no means ‘extremely bad’.
Charging speed and technology
The Samsung Galaxy S25 Edge supports 25W fast charging. Although the charger is not included in the box, the phone gets fully charged in about 70-75 minutes with a suitable charger. It also features wireless charging support, although it is limited to 15W.
Galaxy S25 Edge Design vs Battery
The ultra-slim design of the Galaxy S25 Edge is the main reason for limiting its battery capacity. The thinness and lightness of this device, as well as better heat management, give it a modern and premium feel. But this also led to the battery size being limited to 3900mAh.
Our Conclusion: Is this battery a deal breaker?
Based on our in-depth tests and comparisons, we can say that:
If you are a light user who does social media, web browsing, and occasional video streaming, the Galaxy S25 Edge’s battery will meet your needs.
Gaming or heavy users will have to charge it once a day, but it won’t affect their experience at all.
If you prioritize design and portability, this phone is a balanced choice.
