Alarm not working when phone switched off?

Let's put this one to bed. The alarm WON'T work if powered off. Period. Unlike "ordinary" mobiles. However, the alarm function will work in standby mode, or in flight mode. The latter is useful if you don't want to be woken up by calls or message alerts in the middle of the night. Night night :rolleyes:

I think this guy is not a suitable person to consult for mobile phone problems. Any phone I have bought would sound it alram when the phone is turned off.
Any smartphone as well? It would have to boot up its OS and start necessary system services for sound playback first, which might be a bigger battery drain than leaving it in standby overnight. Especially if you leave it in airplane mode, as someone already suggested.

No phone I've ever owned has had this feature, and frankly, it would annoy the hell out of me to have an alarm go off after I'd turned my phone off when going to the cinema or something.

Using Android I'll go to flight mode for such functionality, and Offline profile (or a custom profile) using my old Nokia.

Off should be off, not mostly off.

The Ericsson R380 - the first Symbian OS based smartphone would turn itself on when an alarm or Calendar reminder was due. It inherited this functionality from the Psion range of hand-held computers for which the OS was originally written. Later models (P800 onwards) from the newly-formed Sony Ericsson did not have the feature. When the phone was off it was indeed off, not merely sleeping.

The reasons for this change included the possibility of the phone waking up into non-airplane mode when you were in fact flying (in the days when people believed that mobile phones would make a plane drop out of the sky.

It all depends what you mean by "off" and "on". Remember here we are dealing with a smartphone, which will do all sorts of things older phones can't. In order to make sure it is not doing anything at all you can power it off - i.e. you hold down the off switch until the menu comes up and then choose "Power off". That does what it says on the tin - it turns off the power to everything and without power the phone has no functions running. So no operating system, no phone calls, no alarms ..... nothing. When you switch it "on" the power is returned and the o/s boots itself up (eventually).

All 3 of the smartphones (2 WM and now the Android) I have owned had this function.

On the other hand if you turn it "off" with a short press that switches off the screen and puts most of the apps into suspension. But the operating system and core functions continue to run. So if things like phone calls come in or alarms happen then it will turn itself "on" and do what it is supposed to.

So set your alarm, check the volume, and then switch the phone "off" (not Power off) with a short press, and then you will be woken by your alarm, which will switch the phone "on". That is what I do and it works all the time. And, if you want to save power before you switch it off, you can turn on airplane mode (as others have suggested). If it does not work then you have not set the alarm or volume properly, you have run out of juice, or the phone is broke.

As others have said, previous phones we have owned have been able to boot from a powered off state (as you describe above) to sound an alarm.

I believe it works because there is always a little bit of power being used in the off state to control the internal clock or a small processesor or whatever. When that clock gets to the time of the alarm it turns the phone on, and then sounds the alarm.
If the hero however does not have an internal clock or prossesor that is powered when the phone is off, it would not be able to boot from its off state to sound an alarm.
