The upcoming iPhone 16 will feature a new battery with a metal casing, offering greater energy density and, in turn, longer battery life. Apple analyst Ming-Chi Kuo backs these claims.
In a post on X, Kuo said that Apple will adopt stainless steel casings for iPhone batteries, allowing cell density to increase by 5 to 10 per cent while remaining within safety limits and meeting new EU regulations. Purported images of an iPhone 16 Pro battery with a metal casing leaked in late 2023, and reports suggest that Apple is working to make battery replacement easier starting with the iPhone 16.

Under the new EU law, smartphone manufacturers must ensure that users can replace batteries using readily available tools by 2025. Apple plans to achieve this by using electrically induced adhesive debonding technology. This technology allows users to apply a low electrical voltage to remove the battery easily, rather than using thin adhesive strips.
The new battery replacement method is expected to debut in at least one iPhone 16 model later this year and could be extended to all iPhone 17 versions next year.
