Enlarge / Apple’s MagSafe battery pack for iPhone. The headset’s external pack is said to resemble these.

Bloomberg reporter Mark Gurman is at it again, sharing insider details about Apple’s upcoming mixed-reality headset. This time, Gurman shared new details in his weekly newsletter about the headset’s controversial tethered battery pack design.

Previous reports from Gurman, supply chain analyst Ming Chi-Kuo, and The Information revealed that after much internal debate, Apple decided to move forward with a headset design that works with an external battery pack connected by a wire.

This is because including the battery inside the headset would make it too bulky and heavy for some users. Apple employees against this approach argued that it made the headset clunky to use, especially in public.
