4900mAh battery, how long can Samsung Galaxy S25 Edge play games?

The Galaxy S25 Edge is attracting attention thanks to its impressively thin body, giving a premium feel and being light in the hand when used. However, what worries many people is the battery of only 3900mAh - a modest number compared to most smartphones today with the same screen size, usually fluctuating between 4800 and 5000mAh.

Samsung is still confident that the software has been optimized to help the battery life not be affected too much. But words are one thing, the actual experience can be very different. Especially for mobile gamers, who often spend hours on MOBA games like Lien Quan Mobile or Toc Chien, continuous gaming time will be the closest test for this small battery.

To verify, the Galaxy S25 Edge was "battery tested" with two popular games: Lien Quan Mobile and Lien Minh: Toc Chien. The settings were kept constant to ensure accuracy: graphics were pushed to the highest level, screen refresh rate set at 60Hz. Screen brightness was at 70%, speaker volume was also set at 70%. The device played games via Wifi in a closed room, without 4G or 5G turned on. Game Mode was activated with the highest performance configuration.

During gameplay, the Galaxy S25 Edge does not get too hot. With Lien Quan, the device maintains a stable temperature, only slightly warm on the back after a few matches, but not uncomfortable. With Toc Chien, the temperature is slightly higher, can be clearly felt when holding for a long time but is still within the acceptable range for such a thin and light device.

In Lien Quan, with each match lasting from 15 to 20 minutes, battery consumption fluctuates around 4 - 5%. This is a quite reasonable number considering the configuration and high graphics settings.

However, Wild Rift, which is known to be "heavier" with detailed graphics, many lighting effects and moves, drains the battery faster. Each 20-minute match takes about 7-8% of the battery, meaning that if the battery is fully charged, you can play about 8 matches before the device displays a low battery notification (20%).

If you play games in ideal conditions such as a cool house, via Wifi, the screen is not too bright, the Galaxy S25 Edge can last about 10 to 12 Lien Quan matches, or 8 to 10 Toc Chien matches, equivalent to about 4 hours of continuous gaming. This is a "stable" number for a small battery like 3900mAh, but compared to other devices with 5000mAh batteries, it is clearly not comparable.

But if you have a habit of playing outdoors, with maximum screen brightness or 4G/5G connection, battery consumption can increase by about 10 - 12% for each 20-minute Lien Quan/Toc Chien match. At this time, battery life will decrease more sharply, only enough for 6 to 8 matches before needing to be plugged in.

On the contrary, if you reduce the graphics quality, screen brightness and speaker, the usage time will definitely be longer, up to 5 hours of continuous gaming before the battery is low.

In short, the Galaxy S25 Edge is not for gamers who "cheat rank" for a long time on a single charge. However, if you only play a few entertaining matches per day and prioritize a slim and beautiful appearance, this is still an option worth considering, as long as you know the battery limit before buying.
