Reuters reports Apple is coordinating a team to design a new iPhone battery management chip. This news follows Apple’s announcement of plans to design a graphics chip for the iPhone.

Designing its own battery management chip could increase iPhone power efficiency and prolong battery usage. A power chip manufactured by Apple could possibly put iPhones ahead of Android devices in terms of battery life.

The earliest an Apple battery chip could be released is 2019, since the power management chips for the 2017 and 2018 devices have already been designed.
