Picking up a Vision Pro? You’ll find that the battery life is slightly better than you might have expected — but you won’t be able to swap the pack out on the fly.
As pointed out at DaringFireball, you can’t hot-swap Apple Vision Pro batteries and need to entirely shut the headset down first. The Apple Vision Pro has no built-in battery, which means accidentally unplugging it from the battery will shut the headset off. Thankfully, it looks like that won’t be a massive issue — the battery connector is designed in such a way as to make it harder to accidentally unplug the cable.
