Leaked iPhone 16 Pro Battery Design Aims to Improve Heat Dissipation

The new battery, featuring a metal shell, is expected to have a slightly increased capacity and not add to the phone's weight.

Leaked images suggest the iPhone 16 Pro will feature a new battery design with a metal shell, replacing the traditional foil covering, to improve heat dissipation.
The new battery is expected to have a capacity of 3,355mAh, a slight increase from the 3,274mAh battery in the iPhone 15 Pro.
The metal shell is not expected to make the phone heavier, according to the leaker.
The iPhone 16 Pro is still in the prototype stage, and the final design could change before its expected launch in about a year.
The iPhone 15 Pro had faced complaints about overheating, and the new design is seen as a response to those issues.
