iPhone 11, 11 Pro, and 11 Pro Max All Feature Thicker and Heavier Single-Cell Batteries

In a production information sheet, Apple has confirmed the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max all feature single-cell batteries.

Last year, only the iPhone XS had a single-cell, L-shaped battery, with an iFixit teardown of the device revealing that Apple "notched" the internal corners of the battery to prevent undue stress from thermal expansion. iPhone XS Max and iPhone XR models are equipped with multi-cell L-shaped batteries.

Vietnamese website Di Động Việt today shared a seemingly legitimate teardown of the iPhone 11 Pro Max, revealing its single-cell, L-shaped battery. Consistent with Chinese regulatory filings, the battery has a capacity of 3,969 mAh, making it around 25 percent larger than the iPhone XS Max's battery.

The iPhone 11 Pro Max's battery is also noticeably thicker than the iPhone XS Max's battery to accomodate the increased capacity.

With the added thickness comes added weight. Apple's production information sheet says the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max batteries weigh 47, 48, and 65 grams, respectively, while the iPhone XR, iPhone XS, and iPhone XS Max batteries measure in at 46, 41, and 50 grams, respectively.

The teardown also provides a first look at the iPhone 11 Pro Max's triple-lens rear camera lenses and other components. iFixit should have more comprehensive teardowns of all three new iPhones in the coming days.
