Kuo: iPhone 16 Pro Max to bring higher-density battery

We recently saw some comparison images between the iPhone 15 Pro Max and the upcoming 16 Pro Max showcasing their size differences. Now, analyst Ming-Chi Kuo is reporting on the battery of the next-generation Pro Max iPhone, claiming it will feature a higher energy density.

According to Kuo, the iPhone 16 Pro Max’s higher-density battery will offer longer battery endurance in the same form factor as the current battery cell used in the 15 Pro Max. The higher-density battery will emit more heat which is why Apple is rumored to use a stainless steel case that wraps around the battery for improved thermal management.

We previously saw an alleged iPhone 16 Pro prototype battery encased in a similar sounding bracket.

Kuo also suggests that the stainless steel casing will make battery replacements easier which may help Apple comply with the European Union’s requirement for replaceable batteries in smartphones. Kuo claims that Sunway will be the major supplier of the stainless steel battery casings for the new iPhone 16 Pro Max and if the first production runs are successful, Apple may implement the new battery casings on its entire iPhone 17 lineup.
