Help Alarm clock does not work when the phone is off?

Status
Not open for further replies.
I set two alarms, turn off the phone, waited, nothing happened. Did it when the phone was on, alarm went off. Did it in flight mode, alarm went off. So the alarm can't resurrect the phone when its off completely or is it just me?

No it can't. Not many standard electronics can just turn them selves on.

If it's off, there is no power, so the phone doesn't even know what time it is, let alone if an alarm is running. Don't even think all PCs can turn themselves on at a certain time.

My LG KC910 (Renoir) turns itself on for alarm, and am disappointed (and am glad it's being confirmed here) my SII doesn't do this, thought all phones would do it.
I don't like leaving my phone on at night as I don't want to be woken by a call (let alone by the random girls that have been calling me from india, feels like people at the three call centre have been matching up my profile with their unmarried daughter lol), but for me the SII almost compensates for this by letting you kill the data transfer and phone operator connections.

Same like Gearu, when I sleep I turn off my phone. I am now putting it in flight mode. Does anyone know a flight mode app/widget? The way I know of placing it in flight mode is by pressing the power button for few secs. This is the first phone I own which does not turn on for the alarm and something new for me.

Hope you are kidding. Cos your reply couldn't be more technically wrong :p

Most of the devices CAN turn them self on. Its a "NEW" technology called standby :p

Most phones, including smart phones can turn them self on a specific time. Thats how they can perform automatic turn on/off and can sound the alarm when they are off.

This IS a limitation of SGS 2. Being the best smart-phone yet is not a excuse for that :D

Simple workaround:

Use Flight Mode

It's a silly omission. Nokia's symbian phones and N900 maemo phone could both do it. Another omission is no LED message indication. Still otherwise the phone is fantastic...

That being said I charge my phone nightly anyway, so just leave it on now.

There's a tool in the market "tasker" that is useful (if a little geeky) which can automatically switch the phone to flight (or silent) mode overnight & back again in the morning based on time, location etc.

Standby is not the same as "OFF"

Try setting an alarm on your average dumb phone that usually wakes up for the alarm, then remove the battery from it and put it back in.

I guarantee it won't work. That's because when you "shut down" those phones they actually go into a sleep/standby mode like you said; so if you actually remove the battery you get a true power off.

Alarms that turn the phones on are simply illusions.

I agree, for these phones to be able to turn on the alarm when they are "off", they must be drawing power of some description to be able to compare the time against its alarms, but the power they draw are absolutely minuscule. I had an old unused nokia which I didnt turn on for months, and there was still plenty of battery left in it when I turned it on.

Its a nice feature to have and its a shame "smartphones" dont have it.

It's probably because smartphones use more power. More RAM, faster processors, etc. There'd be more of a drain on the battery just because of the components used.

I don't know why anyone would ever turn off their phone except when they are on a flight and taking off or landing.

If you want an alarm clock but don't want calls or email alerts to wake you up, just turn the phone into flight mode while it's charging overnight. The battery life pretty much requires that you charge the phone overnight anyway so what's the big deal?

So, first of all, if I don't turn my phone off at night, the performance is greatly diminished the next day, until I turn the phone off and back on again. Does simply putting it into airplane mode fix this? Because if it doesn't, then airplane mode won't help at all.

Second, like most everyone else, my older, less intelligent phones could do this. While I realize that we all should probably just get over that and move on, the fact that this particular part of the technology seems to have gone backwards is very frustrating, especially for those of us who have relied on cell phone alarms for many years and who are susceptible to losing travel alarms while on the go. Having this feature on a phone continues the line of thought that everything you need (barring food and water) is in one place, and this oversight still seems strange to me.

Third, in regards to the standby vs. off thing: honestly, nobody cares what the "official" terms for the phenomenon is, so long as we can have our alarms still go off and not lose all of our battery life. For me personally, I would like to get that alarm feature back without killing my battery at night and while still gaining the advantage of turning my phone off so it functions correctly the next day. If, while is "standby" mode, I can get that effect, it doesn't really matter exactly what is happening inside the phone.

Lastly, if the "standby" option won't work for smart phones because of their increased resemblance to computers (more power, RAM, faster processing, etc.) why can't most of the phone be shut down, leaving just the clock on and a command that turns the phone on when it reaches a certain time?

As an post script, how does one root their phone? I have searched and can't find a description on how to do this. Thanks :)

Samsung under clocks the processor when the screen is off, so if you put the phone in aeroplane mode and turn the screen off it shouldn't use much power through the night.

Why not just charge your phone through the night and have full battery when you wake up?

The difference between these phones and your "less intelligent phones" is that the less intelligent ones could last for days on a single charge anyway. Smartphones can't.

As for rooting, have a look in the "all things root" subforum on here, it has a comprehensive guide.

I couldn't agree more. All my old Samsung phones would switch on and sound the alarm. My old XDA orbit and orbit 2 both did this and they were old smartphones, running windows mobile. So anyway they did know what time it was when they were switched off.

I am new to Android and very surprised that android phones don't do this. It is particularly useful when you know that you don't have much battery left when you go to sleep and want to be sure that the alarm will go off and wake you up, instead of the battery going flat while you sleep. Would be nice if they did this. Especially as all the phones I've had over the last 10 yrs or more have been capable of it.

I am currently (as I type) waiting for my android phone to charge before I can go to bed because otherwise I might not get up at the time I need to be up in the morning.
