As the saying goes, there are tradeoffs in every design decision. In striving to produce the slimmest phone possible, some features have to be sacrificed. For Apple’s forthcoming iPhone 17 Air, this includes having just a single rear camera and a reduced battery capacity. Similarly, the Galaxy S25 Slim, although equipped with more cameras, will not excel in battery life. Digital Chat Station on Weibo has revealed that both models will feature batteries ranging from 3,000 mAh to 4,000 mAh.
This information is somewhat disappointing yet expected. Neither Apple nor Samsung has adopted the new Silicon-Carbon technology that offers greater battery density—a feature that Chinese manufacturers are beginning to implement in mid-range phones with batteries up to 7,500 mAh. Consequently, the more costly iPhone 17 Air and Galaxy S25 Slim will settle for significantly smaller batteries.
Additionally, DCS indicates that these slim models will challenge the capabilities of heat dissipation and battery endurance. Performance issues have already surfaced, as evidenced by the low Geekbench scores of a Galaxy S25 Slim prototype.
In contrast, some Chinese phone makers are planning to introduce their slim models with batteries of at least 5,000 mAh.
