>turn off your phone

I was wondering about this, smartphones don't turn on when your alarm goes. (So you could just turn it off to bypass the "super alarm"?)

I have vague memories that older cell phones used to turn on when the alarm would ring, but I might be imagining it.

You're absolutely correct. At least Nokia Symbian phones had this feature.

I'm thinking about the old brick phones.

Yes, older phones would turn on to ring the alarm. At least the 3 I owned did, and they were all different brands.

Symbian was on a lot of different brands, so based on a sibling comment I’d say it was a Symbian feature.

Not really it was Siemens c35i era that have no problem with ringing alarm when switched off.
