Ming-Chi Kuo predicts improved battery life or smaller design for the iPhone 16 Pro Max with higher-density battery cells. Apple plans to introduce stainless steel battery cases to address overheating concerns and comply with EU regulations, potentially expanding the design to the iPhone 17 lineup in 2025.
The upcoming
iPhone 16 Pro Max
may feature significantly improved battery life or a more compact design thanks to the use of
higher-density battery cells
. Analyst
Ming-Chi Kuo
, in his latest report on
Apple
's supply chain, suggests that the energy density of the battery cells in the
iPhone 16 Pro
Max will be increased, allowing for either extended battery life with the same battery size or a smaller battery with equivalent battery life to current models.
Apple is reportedly introducing a stainless steel battery case for the first time to address potential overheating issues associated with the higher-density battery cells. While stainless steel is not as efficient as aluminium in dissipating heat, it offers greater strength and corrosion resistance.
Kuo also notes that the use of a stainless steel battery case will make it easier to remove the battery, helping Apple comply with the European Union's forthcoming regulations on mobile phone battery replaceability.
Sunway
, a key supplier, is expected to provide a significant portion of the new stainless steel battery cases. If the mass production of this novel battery design proves successful, Kuo believes that Apple will likely adopt it across the entire iPhone 17 lineup in 2025.
The
iPhone 16
lineup is expected to launch in September, and just like last year, Apple is rumoured to be launching four models—iPhone 16, iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max. Rumours have it that all four models will now have an
Action Button
and even a new Capture Button. The vanilla models are also expected to have a new design for the camera module. Further, the Pro models might feature larger displays.
