The size disparities between the incoming 16 Pro Max and the iPhone 15 Pro Max were recently highlighted in some comparative photos. According to analyst Ming-Chi Kuo, the battery of the upcoming Pro Max iPhone model would have a better energy density.

Kuo claims that the higher-density battery in the iPhone 16 Pro Max will provide greater battery life while maintaining the same form factor as the battery cell currently found in the 15 Pro Max. Apple is believed to utilize a stainless steel case that wraps around the battery for greater thermal management because the higher-density battery will release more heat.

An supposed iPhone 16 Pro prototype battery that was housed in a bracket that sounded similar was previously seen.

Additionally, Kuo claims that the stainless steel casing will facilitate battery changes, which might aid Apple in meeting the EU's need that handsets have removable batteries. According to Kuo, Sunway will be the main provider of the stainless steel battery cases for the upcoming iPhone 16 Pro Max. Assuming the initial production runs of the new battery casings prove successful, Apple might decide to use them for the complete iPhone 17 series.
