iPhone 18 Leak Suggests Big Battery Boost From 3,671 mAh to 4,430 mAh

According to the latest iPhone 18 leak, battery gain is tied to a design change. This was revealed by annotations on leaked image. It would entail dropping the physical SIM tray. A wider speaker and haptic motor reportedly add to the room.

A fresh iPhone 18 leak is putting its battery life in the spotlight, and if it holds up, this could be one of the bigger upgrades Apple's quietly working on. Fresh X-ray images doing the rounds on Chinese social media suggest the standard iPhone 18 could see its battery capacity jump from 3,671 mAh to a sizeable 4,430 mAh, a bump of roughly 20 percent. The images, reposted by known Apple leaker Littertree66, also hint at a shared design language between the iPhone 18 and iPhone 18e. Here is what's being claimed.

iPhone 18 Leak: How Apple Might Be Boosting Its Battery

The leaked Automated X-ray inspection images, carrying the codenames Taycan (iPhone 18) and Nevera (iPhone 18e), reportedly show both units sharing an identical internal layout, right down to the logic board positions, battery footprint, and MagSafe coil placement. 

According to annotations on the Taycan image, scrapping the physical SIM tray freed up internal space, while the bottom speaker and haptic motor reportedly shift from a narrow design to a wider one, together pushing battery capacity up to 4,430 mAh. 

Since this depends on dropping the SIM tray, the figure likely applies to eSIM-only variants. iPhone 17 has a rated 3,692 mAh capacity.

The same leak claims the wide camera module is physically smaller than before, hinting at hardware changes even though sensor resolution reportedly stays the same. A component tagged “BG1 Array” sits beneath the rear cameras, likely linked to the second camera.

iPhone 18e Could Get The Same Battery Boost

The Nevera image, representing the iPhone 18e, reportedly adopts the same Taycan design, which would raise its battery capacity by around 10 percent too, up from the iPhone 17e’s 4,005 mAh to the same 4,430 mAh figure.

Worth flagging though, this iPhone 18 leak remains unverified, carry an OpenAI watermark likely from translation tools, and may represent pre-production hardware rather than final retail specs.
