New iPhone 17 Air could feature advanced silicon-anode battery technology from Japanese supplier TDK.
TDK is advancing its production timeline, aiming to ship the new batteries by the end of June, potentially allowing smartphone makers to incorporate them in thinner models this year.
The silicon-anode batteries from TDK offer 15% more energy in the same space compared to traditional batteries, crucial for maintaining battery life in slim devices like the rumored 5.5mm thick iPhone 17 Air.
Future iPhones, including the 2027 model, may also adopt more advanced silicon battery technology, enabling significant improvements in energy storage capacity.
