Ability to detect if this feature is active? #3

After a site has requested to be in a battery savings mode, would it be possible to know that it's active?

Some use cases:

The site owner may want to know if they're in the reduced-framerate or reduced-script-speed mode, and delay or skip specific work
As an analytics provider, it would be useful to know which pages were operating under reduced-framerate or reduced-script-speed mode, to be able to segment user experiences into buckets with the feature on or off

Both of these are excellent points. Do you think the site would need to know the exact mitigations which are active (reduced-framerate or reduced-script-speed) or just that the battery-savings mode is activated.

More granularity always helps, as long as it doesn't bring security/privacy concerns with it.

Is there any update on this question? I was also wondering the same thing, I know they are mentioning about the media queries but is that already a thing we could use to verify the feature is active?

Hi, guys. One question (not sure that this issue is a right place): would there be an option to disallow power saving mode? I mean by meta tag value, for instance?

<meta name="battery-savings" content="disallow">
