After watching WekiHome teardown of the S25 Edge, my frustration with its 3900mAh battery has eased a bit. Given the phone's slim design, the battery can only be 3.6mm thick—for comparison, the Xiaomi 15 Ultra's battery is 6.3mm, which is thicker than the entire S25 Edge body. Plus, the S25 Edge's battery area is standard for a 6.6-inch device. Even if you used the highest-density silicon-carbon anode battery available domestically, you'd only get around 4500mAh—not a massive improvement. That realization makes me feel more at ease—under current technological limitations, a 3900mAh battery in such a thin body isn't entirely unreasonable. As for netizens speculating, "If this were made by vivo or OPPO, it would definitely have a 6000mAh battery," that’s just wishful thinking. It’s simply not possible. To sum up, the S25 Edge's battery density isn’t as low as we imagined, and its theoretical upper limit at this stage is only about 4500mAh—not significantly higher than the current 3900mAh. Now, I can forgive Samsung for this.
