RE: Battery Status Event

As promised, we discussed the Battery Status spec in this week's Web Performance WG conference call. Based on the discussion on the call, the WG is happy with the spec. From a Web Performance perspective, we feel that giving web developers more information on the system, like battery status, will only help developers create sites that are more power conscious. We liked the simplicity of the spec and felt that it covered important aspects that would allow management based on the battery status.

The one question we did have was whether the initBatteryStatusEvent() was needed. I would love to understand your motivation to include it?

Thank you Robin for bringing this to our attention.

Web Performance Working Group, I will include discussing feedback on the Battery Status spec on the agenda for our next conference call. Please kindly review the spec prior to the call.

Dear Web Performance WG,

I am writing to you on behalf of the Device APIs WG. We've put together a small and simple specification that provides information about the status of the device's battery. You can read the editor's draft at:

We're considering taking this draft to Last Call soon and since reacting to battery status is related to performance management (in fact we nicked an example from you) we'd appreciate if you had the time to review our draft and provide us with feedback.
