Samsung Galaxy S25 Edge: Slim Profile, But How's The Battery.
Samsung got aggressive with the Galaxy S25 Edge, making a mind-bogglingly slim phone at just 5.8mm. To achieve that waif-like figure, though, a sacrifice had to be made: a 3900 mAh battery. That's considerably smaller than the 5000-6000 mAh giants in many other flagship phones. So big question, how does it actually hold up in the real world. The folks at TechDroider decided to find out.
The Gauntlet: Real-World Endurance Testing
To provide a clear image, the Galaxy S25 Edge was subjected to the test together with a list of heavy users: the iPhone 16 Pro Max, Galaxy S25 Ultra, OnePlus 13, Xiaomi 15 Pro, and Pixel 9 Pro XL. The test was a combination of typical tasks – gaming, video watching, web browsing, social media scrolling, and camera usage – all activated at the same time on these phones.
Round 1: The Gaming Marathon (PUBG Mobile)
After three hours of heavy PUBG Mobile, the Galaxy S25 Edge surprisingly still had 62% battery remaining. That was quite decent, particularly when you consider the Pixel 9 Pro XL, which boasts a notably bigger 5060 mAh battery (that's 30% greater capacity.), was just a little better at 64%. The Galaxy S25 Ultra (5000 mAh) did a tad better, draining 30%. Surprisingly, the OnePlus 13 with its massive 6000 mAh battery was only 1% more drained than the S25 Ultra. The star of this round was the iPhone 16 Pro Max (4685 mAh), however, as it only lost 20% of its battery during the three-hour gaming session.
Round 2: Video Playback and Web Browsing
Following gaming, another three hours were spent on video playback. By this point, the Galaxy S25 Edge was at 43%. The Pixel 9 Pro XL was once again near the bottom, at 45% battery life left. The test moved on to two hours of web browsing. After this, the S25 Edge was at 32% left, actually ahead of the Pixel 9 Pro XL, which was at 30%. For context, the iPhone 16 Pro Max was still cruising with 60% battery.
The Final Countdown: Who Lasted Longest.
So, how did it all end. The Galaxy S25 Edge went down first with a total of 10 hours and 40 minutes. The Pixel 9 Pro XL managed to stay in for just 13 minutes longer. The Galaxy S25 Ultra was the third to fall, lasting 11 hours and 45 minutes. The OnePlus 13 took three minutes longer than that. The Xiaomi 15 Pro lasted 12 hours and 22 minutes.
And the overall battery champion of this particular test. The iPhone 16 Pro Max, which finally surrendered after an excellent 12 hours and 38 minutes.
Although the Galaxy S25 Edge didn't win the endurance race, its smaller battery held up better than its capacity would have suggested, especially during the initial gaming session. It's clear that Samsung has done some commendable optimization, but for outright longevity, bigger batteries still rule.
