The battery capacity of Vision Pro will be 6500 mAh. According to analyst941, the developers did this on purpose: since an external battery can be put in a pocket, a large-volume battery can be uncomfortable. A battery with this capacity will allow the headset to work autonomously for up to two hours.
An insider noted that when the Vision Pro goes on sale, Apple and other manufacturers will offer several models of external batteries, including a larger capacity for the headset.
