S8 has this, but can be opted out (plus it has what I assume is a whitelist of pre-approved apps, but even those can be opted in, IIRC). It's clumsy, but sort-of works. It does break some old apps that rely on scheduled wakeups, though :(

Also the Samsung variant will not kill the app or service that is showing a notification as it should. So the three problem is limited to apps relying on dumb running in background.
Alarm scheduled wakeups get rounded to a minute in power saving mode though.

Seems it's mainly an issue with Nokia devices, the other manufacturers were minor problems in comparisons.
is this a bug that sometimes happens? how rare is it?
