Apple reveals the iPhone 18 Pro and iPhone 18 Pro Max's battery capacities

Apple unveiled the iPhone 18 Pro and iPhone 18 Pro Max yesterday, and today the company has done something that it really doesn't enjoy doing: publishing actual specs. Thanks to the EU, Apple has to make the phone's Energy Labels public, which it did today. You can see them below.

This means we now know what the iPhone 18 Pro and iPhone 18 Pro Max's battery capacities are in the EU. The former gets a 4,056 mAh cell, the latter a 5,391 mAh battery. These are rated capacity numbers, not the typical capacity that phone makers advertise, so it's hard to compare them directly to the previous generation. The iPhone 18 Pro has a 1.45% larger battery than its predecessor, while the iPhone 18 Pro Max has an 11.8% bigger cell than the iPhone 17 Pro Max, but that's comparing the smaller rated capacity of the new models with the larger typical capacity of the old ones. So in reality the delta will actually be somewhat higher.

Also, keep in mind that Apple is selling the iPhones in the EU with a physical SIM slot. In other markets, the company is offering the devices without a physical SIM card slot, and those units have larger batteries as a consequence of the extra space.

As you can see above, the EU Energy Labels for the new iPhones reveal an A general rating for both, a B rating for drops, a C rating for repairability, and the fact that they are both IP68 certified for dust and water resistance. Their batteries are promised to last for at least 1,000 cycles before the capacity drops below 80%. Unsurprisingly given what we know about their battery capacities, the iPhone 18 Pro Max is rated to last longer on one charge than its smaller sibling.
