Supply chain check reveals strong possibility of longer battery life for iPhone 16 Pro Max

Kuo adds that the battery for Apple’s upcoming 2024 top-of-the-line handset will use a stainless steel case for the first time which will keep the battery from overheating. The analyst says that using the stainless steel case will make it easier for the battery to be removable, which is something that the European Union’s Digital Market Act (DMA) will eventually force smartphone manufacturers to offer in the region.

While the report focuses mostly on the battery earmarked for the iPhone 16 Pro Max, Kuo does state that if mass production of the new battery design goes well and the feedback is positive, we could see Apple upgrade the energy density of battery cells and use the stainless steel battery case on all iPhone 16 models.

The analyst says that his report is based on a check of Apple’s supply chain which showed that Apple is doing business with a company called Sunway. This company is a major supplier of stainless steel battery cases. A leak like this is right in Kuo’s wheelhouse.
