Apple Reveals iPhone 18 Pro and iPhone 18 Pro Max Battery Capacities

[MacRumors]

Apple has confirmed the battery capacities for the iPhone 18 Pro and iPhone 18 Pro Max models that the company announced earlier today.

Apple is required to publish energy labels on its iPhone product pages in the EU, and they reveal the official mAh battery capacities for the devices.

Here are the battery capacities for the iPhone 18 Pro and iPhone 18 Pro Max models that still have a SIM card tray, according to Apple:

• iPhone 18 Pro: 4,056 mAh (+1.7% vs. iPhone 17 Pro's 3,988 mAh)
• iPhone 18 Pro Max: 5,391 mAh (+11.7% vs. iPhone 17 Pro Max's 4,823 mAh)

Notably, the iPhone 18 Pro Max has received a much larger battery life increase than the iPhone 18 Pro did compared to the previous generation.

eSIM-only models of the iPhone 18 Pro and iPhone 18 Pro Max will be available in Bahrain, Canada, Guam, Japan, Kuwait, Mexico, Oman, Qatar, Saudi Arabia, the United Arab Emirates, the U.S., and the U.S. Virgin Islands. The devices have a SIM card tray in all other countries around the world, including in the U.K. and the rest of Europe.

eSIM-only iPhone models are equipped with a slightly larger battery that fills the space occupied by the physical SIM card tray.

eSIM-only battery capacities for the iPhone 18 Pro models have yet to be confirmed.

Still don’t understand why they can’t just give people the option if they want an eSIM only device or not. I’d love a bigger battery as I do not use my SIM card slot.

im in the UK and although ive got a physical sim currently, would happily swap to eSIM and get the bigger battery variant of the pro max.

considering i think every provider in the UK now offers eSIM, i dont know why apple are dragging their heels over here considering their previous pushes for change like swapping the micro and nano sim before most providers were ready.

I had to cut my sim card by hand for it to fit in the iPhone 4 before o2 provided legit micro sims....... good times.

Agreed, it’s very annoying

I'm now using Giffgaff eSIM in the UK, but I need the SIM slot for Lobster which is my Spanish service. And getting an eSIM in Morocco is still 'iffy' so I value the SIM slot for there as well. But the general move to eSIM will encourage Lobster and others to make the move, so well done there.

Now we know the Pro has the C2 modem.

The 18 Pro lasting longer than the 17 Pro Max despite having a smaller battery shows how efficient the N2 node must be. I don't remember anything similar happening in the past.

Still waiting for deepdives about the screen. Could be the M16 too.

Always good to have bigger battery and nice to see that Pro Max with physical SIM now has a battery greater than 5000mAh.

So as a UK person we get screwed again with a damn SIM slot; just get rid of it.

I think they said something wrong. Video playbacks are both worse on 18 pro vs 17 pro max

Why I’m not that keen to switch to an eSIM.

Noticed this too. Was excited bc i want to go to the regular size. But the website does not back this up. Haven’t seen any reporting on it but seems like a big mess up.

That adds complexity to supply chain and manufacturing that means more costs leading to lower margins or higher prices - unnecessarily so in 2026 as the average consumer could care less about a physical sim.

this is a shame, and a reason I will stick with my 15 Pro one more year.
