According to the current technology development trend, it is expected that the iPhone 15 battery will use more advanced materials and technologies to improve the battery life and charging speed.
There may be higher energy density batteries, such as graphene batteries or alumina batteries, that can hold more power in a smaller volume.
In addition, faster charging technologies, such as fast charge or super fast charge, may be introduced to shorten the charging time.
In addition, Apple may also optimize at the software level to reduce the energy consumption of the battery through a smarter battery management system, thus extending the service life of the battery.
The iPhone 15 battery may have the following changes:
The iPhone 15 battery capacity has improved over the iPhone 14 series, with the battery capacity of the iPhone 15 and iPhone 15 Plus increased by 18%, while the battery capacity of the iPhone 15 Pro and iPhone 15 Pro Max increased by 12%.
The iPhone 15 series will be powered by the new A17 processor, which will use TSMC's 3nm process, a generation and a half ahead of the 5nm improved 4nm process still used by the Android camp.
