Apple's internal design changes that improve thermal regulation in the iPhone 16 models also have the added benefit of making the battery easier to access for service, a feature that will help Apple comply with European regulations.
The internal design of iPhone 16 and iPhone 16 Plus has been reengineered to allow for an even larger battery and to better dissipate heat, while making battery service easier.
Earlier this year, a report from The Information suggested that Apple would introduce a new battery replacement method in the iPhone 16 models as required by a new European law. The EU is requiring smartphone manufacturers to make sure batteries can be replaced by users with easily accessible tools by June 2025.
We'll need to wait for a teardown to confirm other battery changes, but The Information's report also said that Apple would use a different type of adhesive that's easier to remove. Apple typically uses adhesive strips to hold the battery in place, and the adhesive is tough to deal with. The new method could involve an electrically induced adhesive debonding technology.
Using low voltage electricity to remove a battery would require a battery encased in metal, and images of an alleged iPhone 16 battery with a metal casing leaked late last year. Metal around the battery has the added benefit of improving thermal regulation. These internal battery changes will be able to be confirmed after the iPhone 16 models are released.
Apple's mention of an easier to service battery is only in the iPhone 16 press release, and not in the press release for the iPhone 16 Pro, so it is not clear if all models have the same battery-related changes. Apple did, however, change the thermal design in both models, with the changes described during the keynote event.
