iPhone 16 Pro Max to Feature Enhanced Battery Technology

Apple's upcoming flagship may include higher energy density cells and stainless steel battery casing for improved performance and durability.

The iPhone 16 Pro Max is expected to have batteries with increased energy density, potentially extending battery life or reducing battery size.
Apple plans to use stainless steel for the battery casing, enhancing durability and making battery replacements easier.
The new battery design aims to address heat dissipation challenges, with stainless steel providing better protection despite lower heat dissipation efficiency than aluminum.
If successful, this battery technology could be adopted across all iPhone models in 2025.
Other iPhone 16 models are not expected to feature these battery upgrades.
