The Samsung Galaxy S25 Edge is generating significant buzz as one of the most talked-about smartphones of 2025, primarily due to its ultra-slim design. However, one of the biggest fears surrounding this device is its relatively small battery size. With a capacity of just 3,900 mAh, the Galaxy S25 Edge's battery is smaller than the 4,000 mAh battery found in the standard Galaxy S25, which features a smaller screen. This raises the crucial question: Is the battery size a deal-breaker for potential buyers? Recent tests provide clarity on this pressing concern.
To assess the battery life of the Galaxy S25 Edge, we conducted comprehensive battery tests that focused on various activities, including web browsing, video playback, and gaming. The results reveal a mixed bag for users:
Phone Model Battery Capacity Browsing (Hours) Video (Hours) Gaming (Hours) Samsung Galaxy S25 Edge 3900 mAh 16h 40m 7h 44m 9h 38m Samsung Galaxy S25 4000 mAh 18h 29m 8h 1m 12h 20m Samsung Galaxy S25+ 4900 mAh 19h 4m 8h 56m 13h 31m Samsung Galaxy S25 Ultra 5000 mAh 20h 49m 8h 54m 14h 21mThe Galaxy S25 Edge scored notably lower than its counterparts, including the Galaxy S25+ and the Galaxy S25 Ultra. In our web browsing test, which is considered the lightest activity, the S25 Edge achieved 16 hours and 40 minutes, falling nearly two hours short of the Galaxy S25's performance. For video streaming, the S25 Edge delivered 7 hours and 44 minutes, which is only slightly less than the smaller Galaxy S25. However, in the realm of 3D gaming, the S25 Edge managed only 9 hours and 38 minutes, trailing behind all other S25 models.
In terms of total screen time, we estimate that users can expect around 6 hours and 22 minutes of usage from the Galaxy S25 Edge. This places it behind the Galaxy S25, which has an estimated usage time of 7 hours. Notably, the Galaxy S25 Edge ranks 87th in our battery life rankings for smartphones tested over the past two years, with the average battery life across devices being around 7 hours and 3 minutes.
Interestingly, the Galaxy S25 Edge outperforms some popular mid-range smartphones. It surpasses the iPhone 16e, which scored 6 hours and 4 minutes, and the Galaxy A35, which managed 6 hours and 12 minutes. Additionally, it is comparable to the Galaxy S24 FE, which achieved 6 hours and 20 minutes. While the initial battery life results for the Galaxy S25 Edge may not appear stellar, they are not entirely disappointing either.
As we continue to test the Samsung Galaxy S25 Edge over the coming days, we will provide further insights into its real-life battery performance. Stay tuned for our comprehensive review, where we will delve deeper into all aspects of this intriguing device.
