Can my FreeRunner remind me to shut it down if it is still running at 22:00?

That could be interpreted as meaning I frequently forget to go to bed too.

No, the phones I have do not wake me.

A phone that literally *rings* (i.e., has a real bell instead of an
electronic tone) may wake me, though. :)

I was thinking more of “to save the battery runtime for when I am awake and
can actually use the phone”, but I guess it could be considered to be
preventing (or at least reducing) climate change too.  I already have 2
tower PCs running almost all the time at home, but at least they both have
80plus PSUs.  My tower PC at work is running almost all the time too, but it
needs to be running at night for the backup system.  It has an 80plus PSU
too.

In this case you literally meant off the hook, but at first I thought you
meant “no longer responsible for”. :)

Yes, this is what I was thinking of.  I am afraid to leave battery-powered
devices plugged in (line-powered) all the time, though, because doing so
seems to kill laptop batteries.

 Or if I am using the phone. ;)
