Do Android phones wake up if the alarm goes off and the power is off?

If your Android alarm goes off but the power is off, does the phone wake up and sound the alarm? I know the iPhone doesn't do that.

From what I've read, it's not an android limitation and it could be done, but would require extra hardware like a RTC that can tell the phone to turn on, so none of the manufacturers bother.

Not to my knowledge. Only BBs and Symbian Nokias know how to do that...
But maybe I'm misinformed?

I wonder if, given the current 'climate', it would go down well
with privacy campaigners, if phones could be turned on without the user doing it manually?
In the days of Symbian and Blackberry devices something like PRISM was tinfoil talk...
Now we know better.
Nefarious *cough* um, intelligence agencies CAN make your phone
do things even when powered down... But they need physical access to add what they need.
That IS not tinfoil talk. You can find the sh*t online easily.

So, I doubt currently any manufacturer wants do something to draw further attention to
the potential of evil in our pockets.

I use flight mode on a Samsung S3 to get around this. The alarm still sounds but the signal to the phone and wifi e.t.c. is switched off so you save battery without having to turn the phone off. I use it overnight and I find that the battery only goes down by a 2-3 percent by the morning.

Yes, that is the best workaround. It's probably not good to have the radio
on and near your head all night, anyways.

Mildly off topic, but old Samsung phones (wayyyy pre-Android) could power themselves on for the alarm.

It's an option on my newer, but basic, Samsung E1150i (a phone which cost me about a fiver) and I remember it also being an option on my ancient Samsung E250 and D900i. I can't imagine they're the only three Samsung phones which can do it either, though I can vouch for the Note 2 and Galaxy S2 being unable to perform this basic function which their £5 cousin can. I found that mildly amusing... To be honest, I always assumed it was an Android limitation seeing as Samsung feature phones can do it.

All feature phones can turn on and sound an alarm - I don't remember having a single phone that wouldn't sounds an alarm. This functionality was removed from smartphones, possibly due to extra hardware costs or what Jan said.

It dangerous to keep active phone next to yourself when you sleep, considering that you are likely to do this for 20 - 30 years. Switch off data completely, voice call functionality only needs passive connection where phone is not communicating, but only listening to cell tower broadcasts.

Motorola RAZR D3 does this.
You can switch it off and the alarms will sound and give you options to dismiss or turn the phone on. Currently running Android Kitkat.4.4.2.
It´s a shame the newer Moto G and Moto X can't do this.

Xiaomi's MI3 can definitely power up for an alarm from MIUI v6 onwards.
