After designing its own CPUs and GPUs, Apple is now reportedly designing it sown power management chips for use in 2018 iPhones. With this move, Apple wants to cut down on its dependence on Dialog Semiconductor while also boosting the chip capabilities according to its needs.
As per Nikkei’s sources, Apple will be replacing at least a part of half of its power management chips going into the iPhones by next year. However, as per another source, the switch will only happen in 2019. Power management chips are used in phones to control the charging function, battery management, and regulate power management of other components.
“Based on Apple’s current plan, they are set to replace partially, or around half of its power management chips to go into iPhones by itself starting next year,” said the source. Another person said Apple was indeed developing its own power management chips for iPhones but the time frame was less certain and could be delayed to 2019.
Apple is currently the biggest customer of U.K. based Dialog Semiconductor accounting for half of its revenues. The power management chips are among the most expensive components used by Apple inside the iPhones after the chipset, NAND and RAM chips. Whenever Apple makes the switch to its own custom-designed power management chips, it would get them manufactured from TSMC.
Apple’s power management chips are expected to be among the most advanced in the industry. By designing its own chips, Apple would be able to better integrate its software and hardware that would allow it to achieve a higher level of power efficiency. This should allow the company to offer improved battery life and performance compared to other smartphones in the market and also give it an edge over other vendors.
