A leaker by the handle ‘Kosutami’ posted alleged iPhone 16 models with a new battery design.

In an X post, Kosutami said that the ‘early stage iPhone 16 Pro’ has a 3,355mAh battery, a metal shell, and limited charge voltage technology. He also mentioned that the stage prototype has changed from ‘glossy surface to frosted metal’ and a redesigned connector.

The component images leaked fall in line with rumors surrounding a new battery technology and a new heatsink component to reduce overheating. It’s believed that graphite will replace copper as it has high thermal conductivity, evidenced by filing patents related to the material to act as a heatsink in portable devices. The move from copper to graphene was facilitated by overheating issues affecting the iPhone 15 Pro. Apple will also have a fix that’s coming as a software update.

There is no timeframe on when the iPhone 16 might launch next year.
