Apple might improve the thermal performance of the iPhone 16 Pro battery by using this material

The iPhone 16 Pro is expected to launch in 2024 as the successor to the iPhone 15 Pro, which was launched in September, and details of Apple's next flagship smartphone have already started leaking online. According to details shared by tipster Kosutami (@KosutamiSan) on X (formerly known as Twitter), the company may make a change to the battery on the iPhone 16 Pro that could improve thermal management compared to its predecessor. They headed for the iPhone 16 Pro Max.

A tipster has leaked four images of an alleged iPhone 16 Pro battery prototype from different angles. Although this “early stage” prototype of the component is L-shaped – like Apple's existing iPhone batteries – it is not covered with foil and has a metal shell. The tipster also shared images of the component that reveal it to be a lithium-ion battery, hinting at some of its specifications.

The images suggest that the iPhone 16 Pro may be equipped with a 3,355 mAh battery, which means that its capacity will be slightly higher than its predecessor, which has a 3,274 mAh battery. Apple doesn't reveal the exact capacity of the iPhone's battery, but those details are usually revealed in teardown videos when a new iPhone is released. Increasing the capacity of the leaked battery makes sense, as the iPhone 16 Pro has a slightly larger 6.3-inch display – which makes room for a larger battery.

The tipster claims that the iPhone 16 Pro's battery will be housed in a frosted metal casing – an earlier prototype is said to have a glossy finish. The inclusion of a metal shell suggests that the iPhone 16 Pro will offer improved thermal management compared to its predecessors, as the metal shell may provide better heat dissipation than the existing solution.

Apple's iPhone 15 Pro and iPhone 15 Pro Max were both plagued by overheating issues that were previously thought to be related to the new A17 Pro chip, until the company released software fixes to fix the problem.

However, changes to the battery design will likely result in better thermal management for the iPhone 16 Pro at the hardware level, meaning they may run cooler than their predecessors. These benefits will also be available on the larger iPhone 16 Pro Max model, as it may feature a larger version of the same battery technology.
