Re:Facebook drains users' cellphone batteries intentionally ... by helsinkiandrew on Sunday January 29, 2023 @05:57AM (#34566951)
So they didn't explicitly ship a feature to drain users' batteries, they seem to have shipped a feature that does tests (testing how long downloading different image downloads take etc.) that drains a users batteries.

It's not clear to me why they wouldn't run a few tests for a few seconds across many/all of their hundreds of millions of users so the battery drain would be unnoticeable, rather than enough on a single user where it would be noticeable.

I read it as one of the tests being intentionally draining user's batteries, e.g. to see how important it is to optimize for battery ("we see X% lower engagement from users in the battery hungry category, so we should invest more in optimizing the app for that").
