Tianfeng International analyst Ming-Chi Kuo claims that the iPhone 16 Pro Max will have a battery with increased energy density. This will allow Apple to increase the autonomy of the battery while maintaining its previous dimensions, or to keep the autonomy at the previous level by making the battery more compact.

We don’t yet know what the new battery will be like, but it is worth remembering that the iPhone 16 Pro Max will be larger than its predecessor due to its larger screen. Interestingly, Kuo says that increased energy density will cause the battery to heat up during operation. To prevent the battery from overheating,

For the first time, Apple uses a stainless steel battery case as a thermal solution. Stainless steel does not dissipate heat as efficiently as aluminum, but it is stronger and less prone to corrosion; Therefore, the stainless steel battery case not only dissipates heat but also provides better protection for iPhone battery and system.

Additionally, the use of a stainless steel battery case reduces the difficulty of removing the battery, which will help Apple comply with European Union requirements for replacing mobile phone batteries in the future.
