Apple Reveals iPhone Duo's Battery Capacity

Apple on Friday published an EU energy label for the iPhone Duo that reveals the device has a total battery capacity of 4,883 mAh.

The document appears to confirm a previous leak that showed the iPhone Duo has 2,962 mAh and 1,921 mAh battery cells totaling 4,883 mAh. iPhone Duo is an eSIM-only device, so this battery capacity figure should apply worldwide, as there is no version of the device with a physical SIM card tray that would have a slightly smaller battery.

For comparison, iFixit found the eSIM-only iPhone 18 Pro has a 4,288 mAh battery capacity, and the eSIM-only iPhone 18 Pro Max has a 5,567 mAh battery.

Crackgate? iPhone Duo Owners Report Screens Breaking Along the Hinge

Friday October 23, 2026 11:05 am PDT by
Some iPhone Duos are already experiencing hinge issues that cause display cracks, based on photos shared on Reddit and the MacRumors forums. Almost all of the display faults are right along the hinge, and most result in a line of bright pixels across one side of the screen. An iPhone Duo owner in Australia said his device cracked after being opened fewer than 20 times, and there was no...

Since it’s under 5K mAh, that’s means a lot of yall should just cancel your orders and let us deal with the battery life. Lol

I ordered the Duo and will be getting in on launch day. I figured something would be off about the battery. I'm going to test it out for less than a week but will probably return it and purchase the 18 pro max. Bad battery life is an absolute deal breaker for me. I learned that with the air. That was a total Flop for my use case.
I like how we are saying bad battery life about a product… That has almost the same battery as the 17 Pro Max.
And still significantly bigger than the 18 pro.
5088 (17PM) vs 4883 (duo) is not that big of a difference.
In fact, Apple says that it still gets five hours of additional screen usage over the 17 Pro Max on the outside screen, so unless you plan on leaving the thing unfolded at all times, the battery life should be pretty much identical to the 17 Pro Max, which was already quite good battery life.
And not even comparable to the iPhone Air, which only has a 3100 mAh battery.
But MR gonna MR.

Pretty surprising that the Duo's battery capacity is much smaller than the Pro Max.
There’s not a lot of internal volume. The individual halves are very thin.

So same as the Z Fold 8 and 2 oz heavier. Wonder if that has to do with Samsung using silicon carbide or just the added weight of MagSafe and other components.
Apple is using titanium for the edges, as well as glass and metal for the camera housing on the back.
Samsung is using aluminum for the edges and plastic for the camera housing.
These are absolutely contributors to the lower weight of the galaxy.

I know silicon carbon is early but the Duo seems like a great use case for a pilot ✈️

Oh…. So battery life is going to be terrible.
I definitely don’t think it will be terrible not even close, I’d assume it’s similar or better than the base iPhone 17 might even get close to the 17 Pro. The Air had decent battery life considering how thin it is.
