Hi guys,
Just want to confirm with you that alarm doesn't work when phone is off. To me this is so stupid that I can't believe this is called "smart" phone. How come my prehistoric Nokia can do that?
It's so annoying to keep phone on all night for absolutely no reason, just for a sake of having alarm buzz in about 8 hours. Is this the same case with Android and iPhone?
Should your computer check for emails when it's turned off?
This is why android has deep sleep.

It depends what you mean by 'off'. If you mean a single short press of the power button (which actually puts the phone in Sleep mode), then, at least on my LGQ, the alarm goes off as I would expect. No probs.
If, however, you mean powered down via a long press of the power key and the display of the 'Goodbye' message, then you are truly turning off all functions of the phone and yes, the alarms would be shut off as well.
If you are putting the phone in sleep mode and the alarms are not working, I would try a soft reset of the phone, and if that doesn't fix it, maybe try a full reset then slowing adding applications to see if one is interfering with the alarm function.

Smart phones are not meant to be turned off. The standby mode is for putting the phone to sleep, all apps go into dormant so that very little power is needed to keep the phone and messaging system functioning. If you do not want to be bothered at night by phone calls and messaging, then put the phone on silent (no sound, no vibration). The clock and alarm will still functions, and even though you put the phone into silent mode, the phone is smart enough to still sound the alarm to wake you up. I hope that this will help you.
Yup, by "off" I meant turning the phone off with long press. I'm aware I can turn phone to silent and still have alarm work but that's not convenient because I have to do reverse in the morning. Second, and more important is that while it's on the stand by phone is still checking towers for signal, waiting for a phone call, wifi is still working and phone is checking emails, etc. It's just completely unnecessary battery drain just for a privilege of having alarm sound in the morning.
My old Nokia would sound alarm when it's off and ask me if I want to turn the phone on so I was expecting the same from much smarter phone.
Does anyone know if Android or iPhone work the same way? Anyways, I'll check tomorrow morning with my colleagues. I'm eager to learn if this is WP behavior only because then I could expect update to solve the problem.

What you are describing seems to be a function of just Nokia phone, I have never seen this on any phone that I have. You are wrong about standby, it uses very little battery and all data are shut down. I have an android phone and off is off just like this LG quantum. I believe iPhone is the same. Like I said smart phone are not meant to be turned off.
@Otnos, I believe you are wrong about the stand-by. When my phone is on the stand-by (not off) I can clearly hear when email arrives on my Gmail account which means he's listening WiFi and checking emails while in stand-by. He's of course also waiting for call and sms so phone is draining battery for no reason. Also, if you set your phone to wireless sync with your laptop or desktop, and if happens they are on, phone will start syncing files even when it's in the stand-by.
I just check with colleague who has Blackberry. He set alarm at 10:47 and when he was powering off his phone he got message "Next “ON” time is 10:47am". I would say that's smart, that's how smart phone should behave.
Edit: Since I have data plan maybe my phone was checking email over 3G, not wifi.
Edit2: There is a feature request for this so if you would like to see this please vote here!

Actually, I suspect your Blackberry friend is also putting their phone in 'standby' mode, since power off means 'power is off' -- nothing is working any more, not even the alarms, etc.
You are right, the radios are still on during standby mode, but at a very low power consumption. If you truly do want to preserve battery by turning off the phone at night, the other option might be an inexpensive alarm clock..

i confirm that many old samsung phones that i had and the very recent samsung star S5230 can do that..specifically you could turn your phone off and the phone was automatically turned on from the alarm..you could snooze or dismiss..i miss that feature too..
the reason is that my battery last longer when i charge my phone while is off..

quite a few nokias do that and even a few LGs but I have yet to meet a Widows phone that would do that.
Shut down means a total shutdown. If alarm rings then there is something going on in background and it's not a true shutdown.
y don't you put your cellphone to offline & battery saver mode !
Thats the way it should be. How would you like if you shut down your phone & it rings in the middle of a meeting or an exam?!
Or when you are hiding in a closet, the husvand comes but your "shut down" phone raises an alarm!!!
Just cuz nokia did a mistake does not means it should be carried forward. Thank God this does not happens any more!

No, Nokia did it right. Android, iPhone etc. do it wrong. There are also lots of people who miss this feature with new smartphones. This was special for Nokia phones that you can totally turn off your phone but it still wakes you up - it wasnt a misstake at all. No battery consumption at nights.

An iPhone will turn itself on even if it has previously turned itself off due to low battery to fire the alarm off, and it will blast the alarm off as long as the battery allows it to—or if it is charged, as long as the event lasts. I think it is about half and hour, I really haven't counted the time.
I was expecting this the first day I was forced to switch to Android, I had insomnia that night and I did have to wake up early and ended up falling asleep for half an hour more, thankfully my inner worries were strong enough to wake up by myself, a little late though.

Hi There
Great device but for some reason after installing BT Tools and SPB GPRS Monitor the turn off after so many minutes fails to work.
The setting are correct and I've even used the same settings for both the BT Tools battery profiles but it doesn't work. The backlight goes off just like it should but the unit never powers down. As a result I'm unwittingly chewing through battery power unless I manually press the power button.
Has anyone ever experienced this? If so do you know why? Many thanks in advance.
Update: I have since removed BT Tools and the auto-power off is functioning properly again. Any and all advice will be appreciated.
mmm maybe this is the same problem i am having?
I get messages SMS at 6am every morning (scheduled from work) most mornings when I pick my phone up, it is off and the message is there, some mornings even though when I went to bed the battery was full the phone is dead (backup battery and all) I presume the phone is waking up when the SMS comes in and not shutting down so the battery runs completely dead. Although the blue light on the top of the phone is falshing....
I also run BT Tools and will try uninstalling it and waiting a week or two to see if the problem goes away. It doesn't happen every day by the way it seems to happen maybe every 10 days or so......
OHHH BTW I don't have GPRS Monitor installed, just BT Tools!
You dont put it on charge overnight?
I do, but I find that if I leave it on the entire day I only get 3.5 hours of use out of it and then it needs to re-charge. So it needs to turn off when idle.

I do sometimes but not always especially if it is already 100% (or close to it), it is still an issue IMHO, having to leave the phone plugged in when fully charged isn't a perfect solution and generally I thought not the best for the battery in the long term!!!!
Besides the same thing could happen during the day, if you dont hear the SMS come in and the phone is in the case clipped to your belt and its switched on for an hour, when it need not be on at all!!!!
Don't get me wrong I love the functionality BT Tools provides, it is a fantastic program, I would just like to know how common this problem is? I will also try and contact the author and see if they know of this problem?
Hardest part is that it doesn't happen every time, only sometimes, just makes it harder for the author to track down the cause, from personal experience I hate tracking down these sorts of problems!!!
Boy, I'd like to turn this off. I charge my phone overnight on my nightstand. Sometime in the middle of the night it will turn the screen on, and stay on, with a message indicating that it is fully charge and that requires dismissal. Maybe someone can come up with a hack.
I think it's quite annoying as well, but the screen shouldn't be staying on from an alert. Are you running "No Lock" or something equivalent?
I also find the pop up annoying, but my phone turns off the display after a while... Leaving the screen on just sounds stupid...
On a Vibrant, using this app-thingy
I too would like to turn it off as it vibrates loud as heck when the alert pops up, and I am a light sleeper!
Subscribe! This notification interferes with my Night Clock and I REALLY want to know how to turn it off!
I have the "stay awake while charging" checked in Settings>Applications>Development
So, once it pops up then the screen stays on.
Yes, this annoys me to no end. I hope they create a setting with future updates. Otherwise, I wonder if the clock / desk dock allows you to turn off the screen without these notifications?
Also, has anyone even downloaded the desk dock app? I'm actually kind of disappointed that the screen won't dim any further. Even on 'night mode' it's extremely bright.
+1 for "I hate it". It's pretty stupid. Samsung needs to make this toggle-able in an OTA update.

curious where you saw a desk dock app?
Go to Android Market. Search for 'Samsung'.
There are two apps that - for whatever stupid reason - weren't included: 'Desk Home' and 'Car Home'.
They look kind of tacky, compared to Google's stock apps. I'd much prefer those, to be honest. But hey, they work. You can voice dial very easily, using the Car Home app. Pretty handy.
Try this: go to Tmobile my account app, select the alerts tab and turn off battery warning.

Its fine to charge the phone while its on just not good to use it while charging. As for the pop up that's to make the phone more "green". Trickle charging can waste a lot of electricity so phone manufacturers put that in there, my Cliq did it too.

i personally dont mind the notification, but i keep my vibrant in the G1 sleeve case that came with it because it fits perfectly in there. my screen shuts off after 30 seconds of the notification. i'm sure in a future update samsung may address this, but until then, its really not that big of a deal, just my opinion
This damn notification is driving me nutz! It is interfering with my Bedside app and freezes my alarm so it doesn't go off in the morning. At least that's all I could link it to.
The battery charge is self managing. So I am not sure why Samsung thought that this popup was even necessary. It is not like leaving the charger connected is going cause any harm.

Yeah, it IS that big a deal. Maybe not to you, but to the rest of us. I use the Digital Clock app and keep the phone awake at night (you can set the screen really dim on that clock) for my alarm clock. Well, while the battery notice doesn't interfere with the alarm it is very bright and just the light wakes me up.
And I like my phone fully charged when I wake up, not down 10% because of whatever sleep processes ate electrons in the middle of the night. Especially since Samsung tried to make an iPhone wanna-be (physically) and made it so slim instead of putting a decent battery in it.
Is it normal for my alarm to NOT go off when the phone is turned off but rings as normal when it's on?
I ask this because I sleep at night with my phone turned off. The alarm is set for 6:35 as normal for the morning.
For the past 2 days it failed to go off. The phone was however switched off, I take it the alarm does not ring unless the phone is on?
Should this be true it is strange as the older phones, the ancient Nokia's and Ericsson's used to ring while the phone was off.
My previous HTC Desire HD had the same issue, the alarm would ONLY ring when the phone was on.
Should it be turned off it would not go off.
Why is this? Any way to fix it?
Anyone?
Simple enough,just put your phone to flight mode and turn off the screen,dont power it off and dont mute it.
cuz automatically waking up is not supported by wm/android device.

Excellent idea, flight mode! This way will get undisturbed plus no more than 1 or 2% loss of battery in standby mode...
Also no one can call & disturb me. I though auto wake up wasn't supported, just wansn't 100% sure.
Cheers valest.
Valest, this morning at 6:35 my alarm rang for the FIRST time!!!
You are right about not turning the phone off...
I forgot to put in on airplane mode but thank god it didn't go off and I hardly lost any power...
Over a 7-8 hour period battery dropped from 100% to 98%
What excellent battery the Streak has... Screen brightness is ALWAYS set to 80% too.
I'm half way through the day and battery is still 94%
Lol your battery must be special or you really don't use your phone much. The battery is certainly better than most but not that great.

cpu and screen backlight are battery draining,so turn off your screen and let cpu go idle(set itself to 245mhz) helps a lot.
still,it could be crazier,my streak survived a 3 hours trip with less than 10% battery: turn down brightness,go to flight mode,shutdown unnecessary background app,set cpu to 245mhz.I was reading an e-book back then.

Yeah that's one thing I miss about Symbian. I could set the alarm on my Nokia then shut it off.
I currently use Tasker with a "night saver" profile I created. From 10pm to 6am:
Shuts down cellular data
Shuts down wifi
Shuts down bluetooth
Shuts down GPS
Turns off auto-sync
Drops the volume to "1"
As an alternative: you could buy a dock (i use the slacker dock) and plug it in on your nightstand.
It charges so you dont have to turn anything off and it's upright so it even looks like a clock

Haha, clever idea! But after testing it & only loosing 2% battery it doesn't bother me keeping it on.
I thought it would have taken more power as my old HTC Desire HD had a crappy battery and needed to be charged almost every day with LITTLE use...
Standby overnight would take around 8-10% This is based on a 6-7 hour period, which I think is bad as it's doing nothing...
I've gone through all 24 pages of threads in this forum, and found nothing like this.
When I get a text message or some other message that turns the screen on, it won't turn back off. It's a pain because it wastes battery and since I charge it at night, I don't notice it and it ends up being on all night. I don't want it to burn in or anything.
Screen timeout is set to like 15 seconds, same in GOSMS. I can't figure out if there is any wakelock causing the issue or not.
Any ideas?
Settings -> My Device -> Lock Screen -> "Secured lock time"
It's different than the screen timeout. Maybe that's what's doing it. Not sure.
Edit... probably read it too fast. This is just for how long before the screen locks. Sorry
I noticed the same. I was looking for "Developer" options like I had in the HTC before the GS4, but I can't find it anywhere.
Basically on the HTC had the Developer options that allowed the screen to stay on, even when charging.
On the GS4, like the OP said, if you get any kind of notification that wakes the screen up, it will stay on when connected to the charger.
That's the thing though, is that it does it even when not connected to a charger.
I have my secure lock time set to 3 minutes, but it will do it before or after that 3 minutes. I have read on other devices forums that it is a wakelock, but I can't find anything that could be causing it.
I think I've narrowed this down. Turn off "Smart Stay". When I take off smart stay, my screen shuts off as intended, but I think if you have smart stay on, it will try and detect anything that looks like your eyes, hence staying awake.

If this is really what's doing it, I wonder if keeping your phone face-down when charging would help prevent it. Still though, that's pretty terrible if that's what's doing it. I've only noticed it 3 times in one night, in a certain location. Once I moved my phone elsewhere it stopped.

Power Button Not Working SGS4 Not Sleeping SOLVED
For whatever it's worth, see http://forum.xda-developers.com/showthread.php?p=48871706#post48871706 - maybe that will be helpful.
I'm not sure if my problem is with OxygenOS or Nougat, but I've scoured the internet for months and haven't found an answer
I have two problems that I think are linked to doze mode on my device, and they both occur under the same conditions. First is my alarm clock (Alarm Clock Xtreme) doesn't work in the morning, and second is my Samsung Gear Fit 2 needs manually reconnected each morning. And through troubleshooting I've determined the problem occurs under rather unique conditions. The problem ONLY occurs when my phone is plugged in and sits overnight (so fully charged sometime during the night). Which is most nights, because I want a full battery in the morning.
But if I happen to go to bed and leave the phone unplugged, the alarm clock WORKS in the morning and the smart watch stays connected all night. So unplugged overnight, no problems. Plugged in, alarm clock won't work and Bluetooth connection to smart watch is dropped.
I haven't been able to find an answer in the 3 months I've had my OnePlus 5. Any thoughts?
Specs: OnePlus 5, Oxygen OS 4.5.10, Nougat 7.1.1.
I can also move this post elsewhere if there is a more appropriate area of the forum for this question. But I don't have this problem with my old device.

I actually had another alarm clock app before, that was doing the same thing. And I don't really have an alternate application for the watch.
I've researched this fairly extensively and have only been able to grasp small nuggets of insight. I did find one source on xda (but I can't remember where I saw it) that talked about doze mode acting funny when the phone is plugged in to charge. Basically an inability to wake from doze under certain circumstances.

You can always enable Developer Options and choose the option for the screen to stay awake while charging which should also keep your phone awake. You can also disable Doze completely in Developer Options.

Thanks! I don't want to disable doze, but I might try that other one. My other quick fix I juts thought of is to use a timer switch or smart switch to have the charger shut off after an hour. That's enough to give me a boost, but not fully charge. I tried it last night and everything worked this morning. Though my battery was only at 60%, it was better than nothing.

It's recommended these days to keep your battery charged between 40%—80% to prolong its life and not keep the phone plugged in overnight like in the old days. I charge mine to 80% before going to bed.
If it's actually a Doze issue I don't understand why it wouldn't happen when the phone isn't plugged in. Do you have a screen saver enabled?
Fellow OP5 user here, I have the EXACT same problem.
If I leave the phone charging for long time and doze kicks in, the phone basically shuts down for all purposes until I unlock it with my pattern. Meaning, only the built in alarm (that works even with the phone turned off) will work. Any other (Timely, radio...) won't.
Now here's the kicker: sometimes the deep sleep will cause a weird bootloop, upon which the screen will indefinitely hang on the spinning logo, with the screen turned on, requiring a reboot. And of course this makes the alarm not sound.
This last bit happens at random. If I disable the screen sleeping in Dev options, the alarm will work but when I wake up the pattern input screen would be there, after all night on, which isn't really healthy for the screen.
Turning doze off makes this problem apparently disappear, but I need to investigate some more to draw conclusions. For the time being I sleep without charging, quick charge and the phone's great battery makes it unnecessary to keep it connected all night.
Another fun tidbit of this deep sleep mode: it stops USB tethering. I would have imagined a wakelock in there, but apparently there isn't.
For information : I use vanilla kernel and OOS. I have Magisk on and Gravitybox via Xposed Magisk, but other than that I have nothing particular going on.
I've been hearing that from other sources as well, about not letting it sit overnight on the charger at 100%. Which is why I think I'm gonna keep using the smart switch of my nightstand charger. The OnePlus Dash charging system works great for a quick charge anyways, so having 100% fully charged to last all day long is no longer necessary. I have a normal USB cable at my night stand, so it's a slow charge. If I set the timer to stop after an hour it at least gives me a small charge overnight, without overdoing it. And I have dash charger at work to give me the full quick 20 minute charge that puts me at 60-70%.
No I don't have a screensaver running. It is weird that the phone locks in the doze mode for the alarm and boots me off my watch's BT connection, but only when plugged in and sitting at a full charge for an extended time (haven't stayed awake all night to test just how long it has to sit). But that IS what it IS. Those have been confirmed as the only conditions in which this problem arises. I've been using the smart switch for 3 days now to keep my phone from going to and staying at 100%, and the alarm clock is working again and the watch is staying connected.
It's not that it's a big of a deal for me to have to use a work around like this. I don't mind. But I hate finding a glitch in something and not being able to truly "fix" it. Work-arounds work. But they don't actually solve the problem. This is just a gripe I have in general whenever something like this happens. It's in my nature to want things to work properly. Which is why I haven't had a non-rooted device in at least 5 years. I NEED to have the ability to fix the [email protected]$$ sh1t the software developers and phone manufacturers screw up. Of course, that's probably the number one reason xda exist. This open up the full potential of these devices, because the manufacturers are either too dumb or are financially motivated to not fix things (ahem...Samsung). Thank you everyone who chimed in with advice. I appreciate it.
It has been my experience with this phone so far that doze mode doesn't work. At all. I regularly have widgets that won't update even though I have doze turned off...
Just one of the many annoyances that has me thinking about finally rooting and getting rid of this garbage os...
