The new iPhone 16 will be the first to adopt a new battery design that offers a longer battery life. Ming-Chi Kuo announced in a post on X that the use of a stainless steel shell for the iPhone battery would allow a 5 to 10% higher cell density.
More battery thanks to new coating
Late last week, we learned that Apple was working to make it easier to replace iPhone batteries, starting with the iPhone 16. New EU legislation requires manufacturers to ensure batteries can be replaced by users with easily accessible tools before 2025. Apple already offers this service through its replacement program, but with one key change coming: bonding.
According to the regulations, it is forbidden to use any type of glue to hold the battery in place. Apple is therefore developing a technology to remove the batteries with a small electrical discharge weakening the adhesive. This process relies on a new chassis for the battery.
The move to a stainless steel shell for iPhone batteries represents a significant evolution in their design. A Higher energy density means batteries will be able to store more energy without increasing their physical sizewhich results in greater autonomy and a longer lifespan.
A really interesting change which will start with the iPhone 16 Pro and iPhone 16 Pro Max, before extend to the entire iPhone range with the arrival of the iPhone 17. This improvement, resulting from the simplification of the battery replacement process, will allow them to store more energy thanks to better protection and insulation.
We are talking about several changes here. Simplifying the process of replacing the iPhone battery, it will need to have a metal coating. This coating allows the battery to store more energy thanks to a higher level of protection and insulation. So, starting this year, we will see phones with longer battery life, which is always good news.
