   The iPhone 18 Pro Max might be about to blow past every iPhone battery ever made.A fresh leak doing the rounds this week points to a 5,235mAh battery for the global model with a physical SIM tray, and a bigger 5,425mAh cell for the eSIM only version sold in the US.That's not a small bump.It's roughly 400mAh more than the iPhone 17 Pro Max, which currently sits at 4,823mAh and 5,088mAh depending on the SIM setup, and if the numbers hold up, Apple's biggest phone would finally out muscle Samsung's Galaxy S26 Ultra, which tops out at 5,000mAh.

   The leak first showed up from a Weibo tipster and got picked up by outlets tracking Apple rumors closely.Worth saying upfront, the source isn't exactly a household name in leak circles, so there's real reason to raise an eyebrow here.Still, the figures line up with an earlier prediction from Digital Chat Station, a leaker with a much better track record, who pegged the Pro Max battery somewhere around 5,000 to 5,200mAh months ago.That's two separate leaks pointing the same direction.For a device this far from launch, that's about as close to confirmation as anyone gets.The smaller iPhone 18 Pro is also tipped for a battery increase, going from 4,056mAh to 4,288mAh on the eSIM model, though the jump there is far less dramatic.

   Extra battery room like this usually comes from somewhere, and in this case it looks like dropping the physical SIM tray altogether in the US model frees up space Apple can fill with more cells. The phones are also expected to get heavier, with the Pro Max reportedly climbing to around 242 grams thanks to a bigger vapor chamber and larger camera module alongside that battery.Apple is still holding off on silicon carbon battery tech, unlike several Android rivals already using it, and continues favoring steel cased batteries instead. None of this is locked in yet.Apple hasn't confirmed a single spec, and the iPhone 18 lineup isn't expected to launch until September.
