FAQ

Q： Why does my Quest 3/3S battery stop charging at 80% while I’m using it with a BOBOVR battery strap?

When you use your Quest 3 or Quest 3S while charging (On-Head), the internal system is designed to stop charging the battery at around 80% capacity for safety reasons. Here’s what happens:

If your Quest starts below 80%, it will charge up to ~80% and then hold there—your BOBOVR battery (B100) will take over to power the system. For example, charging from 60% will stop at 80%, and the BOBOVR battery will slowly drain instead.
If your Quest starts above 80%, it won’t charge further—the BOBOVR battery will directly power the headset while keeping your Quest’s battery level steady. For instance, starting at 90% means it stays around 90%, while the BOBOVR battery drains to keep the headset running.

Note: If you’re not wearing the headset, it will charge to 100% capacity
