According to analyst Ming-Chi Kuo, Apple will use higher energy density battery cells in the iPhone 16 Pro Max, which will provide either longer battery life when using the same battery size as existing models, or equivalent battery life using a smaller battery.
In his latest supply chain research, Kuo says The energy density (Wh/kg) of the iPhone 16 Pro Max's battery cells will increase, which “provides longer battery life for the same battery size or a smaller battery for the same battery life.”
According to Kuo To avoid battery overheating, Apple is using a stainless steel battery case as a thermal solution for the first time.
Stainless steel is not as efficient. Like aluminum, it dissipates heat, but it is stronger and less susceptible to corrosion. Using a stainless steel battery case also reduces the complexity of battery removal, which will help Apple comply with European Union requirements for mobile phone battery replaceability in the future.
Sunway will reportedly be a major supplier of stainless steel battery cases become. If mass production of the new battery design goes well, Kuo believes the design will be adopted by all iPhone 17 models next year.
Last June, there were rumors that the iPhone 16 Pro models would use stacked batteries . which could lead to increased performance and longer lifespan, but Kuo doesn't mention this technology in his review. Apple is expected to release the upcoming iPhone 16 lineup in four months, likely around mid-September.
