Analyst believes Apple developing its own custom battery power management chips for iPhone
Apple is believed to be developing its own custom power management chips for iPhone and iPads, at least according to one industry analyst (via Reuters). The report from Bankhaus Lampe said that Apple is looking to replace a PMIC component currently supplied by Dialog with its own custom silicon as soon as 2019.
The analyst notes that Apple has been aggressively hiring engineers from the third-party supplier and already has a significant team of employees working on Apple-designed power management chips. This follows the news that Apple intends to make custom GPUs for its iOS devices within two years.
Power management chips manage voltage and charging across the components in the device. With battery longevity a primary complaint about iPhones in particular, it would make sense for Apple to invest more in that area and replace parts with custom, integrated, designs.
