First Alleged iPhone 16 Pro Component Leak Reveals Redesigned Battery

Images purporting to depict a new battery designed for the iPhone 16 Pro today leaked online, showing a new metal casing and a slightly larger capacity.

The images come from the leaker known as "Kosutami," who has disseminated accurate information about Apple's plans in the past. If authentic, the images are the first to be shared of the iPhone 16's components.

The battery is said to be designed for an early stage ‌iPhone 16 Pro‌ prototype with a 3,355 mAh capacity. The iPhone 15 Pro contains a 3,274 mAh battery, meaning that prototype ‌iPhone 16 Pro‌ models currently feature a battery that is just 2.5% larger. The new battery also features a redesigned connector.

The most significant change is the transition from a black foil casing, the likes of which have been used on every iPhone model thus far, to a frosted metal shell. This change improves the thermal efficiency of the battery, with no significant impact on the component's weight. The Apple Watch used to feature batteries with black foil casing, but starting with the 40mm Apple Watch Series 7, Apple began adopting metal shells for improved thermals.

The early component images appear to confirm information shared last week that said Apple plans to introduce a new thermal system on the ‌iPhone 16‌ to reduce overheating. In addition to batteries with metal shells on the ‌iPhone 16 Pro‌ models, the entire ‌iPhone 16‌ lineup is rumored to feature a graphene heat-sink to reduce overheating. Graphene has high thermal conductivity, surpassing that of copper, which is currently used in ‌iPhone‌ heat-sinks. Apple has been interested in graphene for thermal management for some time, filing patents related to its exploration of the material for heat dissipation in portable devices.

The moves appear to come partly in response to widely encountered overheating issues experienced with the ‌iPhone 15‌ Pro, which Apple ostensibly addressed through a software update earlier this year.

Sounds like a minor improvement at best, while searching for better battery tech, such as graphene or solid state.

BUT: Can you believe anything you read on X these days? It's a cesspool of lies, disinformation and the lowest forms of human behavior, all of it heartily endorsed by its owner.
What kind of nonsense is this. Did Elon musk post this rumor or did he hack this account which had been there before he took over . What a stupid comment. Also I am pretty sure the same people i follow did not become a bunch of liars because of the person that owns it. Maybe you should follow better people

I don't follow anyone on X. I've never had an X account, and never will. Your angry response just confirms my belief that X is only populated with angry extremists, who will brook no dissenting opinions.
So you never had an account, followed one single person or anything on there and never posted but you can think you can make a judgement about a platform you never used. And somehow I am an angry extremist because I accurately called your post nonsense.

‘Can’t wait for this’, ‘can’t wait for that’; it won’t do anything differently from current models. The watch 8 didn’t significantly improve battery life over the 7 moving to metallic battery casing. So, I definitely don’t believe there’s going to be anything radically different from what we have now, despite all the technical, environmental and ‘ethical’, mambo-jambo Apple would try to throw at us.

If anything they’d charge more. That, I’m sure! They took away leather cases and brought sh*tty woven nonsense - which costs more - that you use and discard the next day.
