Battery level

[toji]

Simple feature request: For controllers where it's applicable and that expose it, it would be nice to be able to advertise the battery charge level. Could be used for on-screen prompts (telling players that their battery is low and they may want to charge/change batteries before continuing) or in VR cases for displaying battery level on the in-world controller model, which is becoming a common practice.

I would assume we would likely share the interfaces from the navigator.getBattery API (which is obviously intended for batteries for PCs/mobile devices).

With orientation, pose, display info, gamepad info, and now gamepad battery level, it's probably worth reiterating the potential concern of trivial user fingerprinting. The topic is not exclusive to the VR/gamepad use cases, but obviously with more i/o, more possible vectors.

Hi,

One possible solution to this could be adding levels of charge: charged, half charged, low battery. With threshold of 1/3.

Hi there,
looking to get involved in this project and this seems like it could be a simpler task for someone newer to open-source contribution. Wondering the best way to go about using the navigator.getBattery interface to potentially return something like a 1 out of 100 for battery level?

We (Editors) still think this is worth pursuing... we hope to come back to this at some point.
