Alarm clock that works when phone powered off

[Thom]

Many of us leave them on all the time ... silenced ... you should have had auto updates in Play Store disabled already (it is a really bad idea).

You could also use a capability like Tasker to customize the environment even further ... play sound that helps you doze off and then goes silent perhaps.

Because their phone is a phone and they're not interested in anything it may/may not do when they're asleep? Smart or not smart.

No. They want it to be an alarm clock when they're asleep. But they arbitrarily want the alarm clock to use this battery, not that battery.

If you take a typical modern Android phone (that doesn't have a separate CMOS battery and alarm watchdog) and put it in "Airplane mode" or "Quite mode" during sleeping hours, your "alarm clock" will cost you maybe 1% of your main battery overnight. On the other hand, a dedicated alarm clock system will use X% of some battery (Li-ion or dedicated CMOS battery which is likely connected to the Li-ion battery). I would expect such a dedicated alarm clock circuit to use less juice, but from what I saw, nobody in this thread measured X% or the Y% that it costs to boot up the phone to sound the alarm. And nobody talked about the use-case that makes the dedicated alarm clock necessary. (1% -X%+Y%=Z% savings which critical because Reason A.)

It wouldn't surprise me if their modern phone (with a modern battery but no dedicated alarm clock) lasts far, far longer than their old phone (or perhaps even lasts longer than a different model of new phone with dedicated alarm-clock circuitry). Maybe not, but I didn't see it discussed in terms of actual usage (%, hours, days, etc.) It seems like more of an emotional or nostalgic longing than a real, data-backed, problem.

I guess I could conjure some extreme use-case where it might matter. Maybe you go camping for 8 weeks with no electricity or cell service but, for some reason, you really want to use your phone as an alarm clock. But it's hard to fault most Android phone makers for not adding dedicated circuitry (additional cost) to a phone in order to handle highly-unusual use-cases that very few people care about.

I'm not sure if this applies to all recent Android phones, however, my Jiayu S3 will power on from selecting the poweroff button after holding the poweroff button. This also works on a Huawei phone thats name I cant remember and the Xiaomi Redmii 2 pro.

I haven't tested this on the others, but the Jiayu will still power on and sound the alarm if it has its battery removed after shutdown.

If that doesn't qualify as being able to power on from full shut down I don't know what will - if you need proof I will make a video

I would just like to add that I am only here because I discovered only today after more than 2 years that my HTC One X will turn itself on from Powered OFF if an alarm is set. I thought that perhaps I had not turned it off properly, but I am able to reproduce the result every time.

Yeah, I had the One X. I've had the; Hero, Desire, One X, One and now the One (M8). Only the One (M8) won't alarm from off. Strange.

I suspect you have fastboot enabled. Basically this puts the device to sleep as opposed to turning it off which is why the alarm still works when the device is "off".

TO all readers of this thread !
There are many android PHONES that can be TURNED off and make the ALARM WORK !! please stop talking bullshit saying they don't EXIST !

i had 2 GIONEE (M3 marathon and another one) phones with android 4.4 and while phone was 100% off it boots bu itself and alarm WOKS!
i had 2 HUAWEI (3c honor lite and another one...) and it has an option to shut off/on at any specified TIME....and after that the alarms works...BASICALLY the same thing....

SO yes there ARE MANY phones that can be shut off 100% and still be able to enjoy ALARM !!!!!!

Say what you want, but the Device is NOT OFF, there is still a CPU and a clock timing module running ALL the time that is using battery power.
And that negates the whole concept of the "Phone being OFF"....

the actual phone functions can be off, yes, but the device as a whole is not OFF and it is still consuming battery power.


Pull the battery out of that device, and I guarantee you, the Alarm Function will never work again.

You obviously don't have a clue as to how electronics stuff works. You cannot violate the Law of Physics.
You never get something for nothing.

It also is irrelevant to the original question - if anyone still remembers that . The fact that a particular phone keeps a process running when Android is shut down doesn't mean that there is an app that you can install on the phone that will give you this ability. This will have been built into the firmware at a lower level than the Android OS, and no Android app will give you that.

I think this is an important distinction. While there are Android phones that "do" do that, it isn't a part of Android or a an installable app. It's just as likely to show up on a Windows phone as it has to be a piece of the firmware. If it isn't provided by OEM, there is no aftermarket solution to enable it.

ok i understand what you are saying...still people here were talking about shutting the phone off with power button...so even if there is a a clock working...battery consumption is very low and will last longer as the phone is "off" every night....
i really don't understand why manufacturers have not done this in EVERY model !! it is a very useful option

and boy windows phone should also have it...as no model has until now!!!

I also had an old Nokia phone, where alarm clock worked when it was off. So i really miss this in my Android.

Alarm clock in Nokia mobile when your mobile turn off its happen with me if you don't believe then you can put alarm according to your desire and switch off your mobile its working fine.

It might happen with Nokias, but when the vast majority of Android handsets are switched off, the alarm won't work.

 

[Alok kumar]

@Ei Presidente, when you put alarm on your "android mobile and then switch off then still your alarm get turn on" you can do practically on your android mobile set.

I don't know what you mean.

99% of Android devices will not alarm when they are turned off. There are exceptions, but in the vast majority of cases, once a device is off, alarms won't ring.

REALLY off vs. MAKE BELIEVE off.

[Vlad Soare]

Old Nokia dumbphones are a totally different matter. They have a separate module in BIOS which is resposible solely for the alarm settings. Even when the phone is off (and it's really off, not just make believe) this module is still powered and active, because it's powered by a separate internal battery. The alarm settings will be preserved even if you completely remove the main battery (although it does need the main battery in order to trigger the actual alarm).
So yes, it is actually possible to have the alarm work while the phone itself is really off. But the phone is designed to do that to begin with. It's not just a matter of software.

 

[K Rize]

My Nexus 7 tablet powers it's self on when the alarm is set, tho i don't know how it does it. I think it may have been when i was on 5.0.2, i haven't checked since being on Marshmallow. This is a good question, and I'm gonna check my devices to see if it still does it. (Stock Android Clock is the only clock I've ever used) and yes, it kind of bugged me out, because i know i turned the thing off, but it's happened more then once, so i know it did at one point in time

 

[bolojohn]

Here's something that will work.

I can't stop laughing....

As previously stated, my HTC One (M8) is the first phone I've owned that won't alarm from off. A few folk reckoned Google, HTC, or both had dropped the feature due to instability issues. Just now, I was reading up on Android Marshmallow and look, a 'new' feature...

Doze
When your device is at rest, Doze automatically puts it into a sleep state. So your phone can still set off your alarm in the morning even if you forgot to charge it. Phew!

But unclear though. Do they mean if your phone runs out of charge or just while in 'doze'/sleep mode?

Doze still has the phone in a powered on state, but it is much closer to what the OP was after. I think Doze is like a dumbphone mode, meaning texts, calls, alarms (according to this) and nothing else. It keeps the rest of Android services in a sleep state greatly extending the life of a charge. The phone is still powered on though.

 

[linkyard]

You had a phone that could be powered off and it would turn itself on and wake you up like a clock? Really? I'd like to know what phone that was.

I thought the original post was some kind of joke when I first read it. Now there are great apps that put your phone into a sleep-like mode and can be configured to only allow certain callers or texters to get through (or none) and then turn on at the correct time and wake you. But work from being powered off? I call BS.

-------------- any nokia and sony ericsson phone used to power on and sound an alarm at the specified time even if the phone was drained off battery and was switched off.

 

[Dingledoodie]

Why are people being so argy about this? Making those of us who've had phone's that did this out to be dumb or lying? As stated several times in this thread... since 1999, when I got my first mobile, ALL my phone's (Nokia's then HTC's) were able to alarm from off. My HTC One M8, bought this year, is the first handset that I've ever owned that won't alarm from off. I'm not insane, I'm not dumb and I'm not lying.

 

[lunatic59]

No one is accusing you of anything. We all understand what you are looking for, but trying maybe too hard to explain why it doesn't exist ... or at least not in the majority of smartphones. I think we're getting too hung up with semantics.

While feature phones from bygone days had alarm features that would ring when "off", they weren't really off. They were in some kind of low power mode that maintained a clock and a little program to trigger a power-on state when a time was reached.

Smartphones ... Android, iPhone, Windows Phone, Blackberry ... with very few exceptions, when they power off, they are off as if the battery were removed.

Android is the OS when the power is on. It has apps that might control things to extend power and disable services on a schedule, but the device needs to be on and powered with an active CPU. The ability to maintain a rudimentary clock and alarm might be able to be engineered into the hardware, but as far as I know it's not there. We all get that you want it. A lot of people do. Some learn to adapt, others rant on forums in the hopes the message gets back to a manufacturer. But, you really can't lay this at the feet of Android or Google. It's really something that has to be built into the hardware.

Let's not get upset over what "off" really means.

 

[Dingledoodie]

I don't care about the sementics nor HOW it's done. I just came here to see if my newest phone had a glitch or if there was a way to turn the feature on.

For YEARS I've used the power button to turn my phone off and the alarm still activated. And, I'm not talking about phone's from a bygone era either. EVERY phone I've owned from Nokia bricks to the latest HTC Smartphones did this right up until I got my HTC ONE M8... THIS YEAR. I switched my phone's OFF. I didn't use an app, I didn't put my phone's into sleep mode. I simply switched them OFF. I'm not thick. I know the difference between all of those things. This is the FIRST phone I've ever owned that won't alarm from off.

 

[Hadron]

I think one reason the tone of this thread is not always what it should be is that the thread is just a few weeks short of being 3 years old yet keeps repeating the same question and the same answers. Maybe it's time to just close it as there is nothing more to say?

Anyway, I'm afraid this is normal for smartphones, even HTC. I once had one software revision on one of my HTC phones that had this feature (which was in the recovery module, so technically the phone wasn't truly off even though it was not running Android and would appear to be fully off). But neither earlier nor later versions had it, and none of the other HTC's my family owned ever had. So I think you may have been lucky before, and am certain it's absence from your M8 is a feature rather than a glitch. In short, if you get that feature you are lucky, rather than the other way around.
