iPhone 17 Air and Galaxy S25 Slim rumored battery capacities will make you laugh

You know how the saying goes – everything is a tradeoff. So when you want to make the slimmest phone possible, something’s got to give. Or, in the case of Apple’s upcoming iPhone 17 Air, multiple somethings. The rumored single rear camera is one compromise made in the name of slimness, and today another one has been revealed: battery capacity.

But the iPhone isn’t alone in this, the Galaxy S25 Slim may pack more cameras but it won’t be a battery life king either, that’s for sure. According to Digital Chat Station on Weibo, both of these devices will have batteries between 3,000 mAh and 4,000 mAh, give or take.

That’s quite disappointing, to say the least, but it’s not surprising. Unlike their Chinese competitors, neither of these companies has started using the new Silicon-Carbon tech that enables more battery density, and we haven’t even heard rumors that they might in the future.

So in a world in which Chinese mid-rangers are soon going to sport 7,500 mAh cells, the much more expensive iPhone 17 Air and Galaxy S25 Slim will have to make do with a lot less.

DCS further mentions that these slim devices will put heat dissipation and battery life to the test, and regarding the former things are not looking good, performance-wise, if we go by what a prototype Galaxy S25 Slim managed to score in Geekbench recently.

The good news is that several Chinese smartphone makers are apparently considering launching such models of their own, and these will all have at least 5,000 mAh batteries, as they should.
