I like having my LED notification light on as much as the next guy, but I think it's preventing the phone from going into deep sleep, and while it may be running one core at a low clock speed, it still is using a enough voltage to drain the battery rather quickly. If you look at your battery usage and the phone says "Awake", that means that the CPU was doing something at the time and I've noticed it's always awake whenever I have a notification.
Is there a way to let the phone sleep and have LED turned on, or is it just a design flaw in Android?

If that is actually happening, it's a bug - but not one in android. On both the international sgs3 and the gnex, the phone turns on the notification LED (or turns it on in a "flash" mode) and goes back into deep sleep.
The processor should NOT be needed for handling that LED once its started - it should run on it's own.

Hi
I have noticed something strange happening with my phone. I have started charging it every night now so that it will be fully charged the next day.
When it is fully charged, I turn it off completely to save the battery, and to stop noisy email alerts. In the morning I turn the phone back on and it says 73% battery level, despite being turned off overnight, so nothing should be draining the battery.
If I leave the phone on Standby overnight the battery level is always 90%+ the next morning.
What the hell is going on? Does anyone else notice this quirk?
You can try another battery and oberve if the problem would still occur..
It could have something to do with the difference in temperature? In the morning it's coooled off and maybe that does something with the measurement?
Did you put ur fone into flight mode.

Huh, I've never heard of that before, but then I never turn mine off. When you say "turn it off" I am assuming it is when you hold down the off button for a few seconds and answer yes to "really" turn it off. I think its very strange that it uses more power off than in standby. Maybe you have come across a nasty hardware bug. Keep us posted.

Yes I do mean holding down until it tells you data may be lost are you sure.
And it is still doing it. If I fully charge my phone at night and then leave it on standby the next morning the battery gauge will say something like 96%.
If I turn it off, it is always under 80% the next morning, this makes no sense. I leave the phone in standby now with the volume off, and the backlight and power set to switch off.
I keep it in a cradle now, this is a stock photo, not my phone in the cradle.
Charge your battery to FULL, then take it out of the phone when going to sleep, when you WAKE up, put the battery in, if it's at 100% or 99% then it's your PHONE. If it's at 96% like you said before then it's your BATTERY.
Memory card draining power
This was a ROM bug on i-mate JAMin on the first ROM versions that was available. A memory card inserted will drain power from the device. What brand do you have and do you have a memory card inserted ?
I went to bed with the phone charged to 100% or atleast very close to it since it had been plugged into my laptop for a few hours.
Unplugged it and left it at bedside at 12:00am
Checked the time at 7:00am (didn't bother to look at battery life).
By 10:00am the phone wasn't responding, kept rebooting with a red battery icon. I plugged it into the wall charger and it booted up showing 0% on the battery.
I also had it on low power mode: everything off and mobile data set to 2g only. I also had no activity on the phone: no calls, emails or notifications.
I've done this before and I'll usually wake up to it in the 90% area of battery life, but now it's completely dead?!
Anyone haves omething like this occur?

Mm.. well, first thing I'd do is check your widgets/apps running. Some of them leave a WakeLock open, and force CPU to run at 100%.. that'd kill the battery.
Another thing to check is any big data parsing apps, like RSS with webpages for example (NewsRob).. they are excellent apps, but if you set them up for constant sync they will kill ur battery.
Unless your battery is a complete mess, there is no reason why it should drain so fast, unless there are some nasty apps running.
BTW, check out this thread: http://forum.xda-developers.com/showthread.php?t=669497
You really don't have to worry about using 2G over 3G (EDGE drains MORE power than 3G, actually) and turning everything off for battery power. Your problem is elsewhere.
It happened to me once. Woke up to a completely dead phone. I assume something I was running got out of hand. Nothing I had installed regularly kept it awake, but it could have been a bug in something that used 100% CPU, or at least kept the CPU awake the whole night.

It's small things, for example a CPU meter widget I had secretly ran a WakeLock and kept my CPU at 998MHz all the time to monitor it.
Or, could be just a poorly written app/widget. Not saying that this is the definite reason, but this is the first thing I'd check for.
how do i know if my phone is set at 324MHz even on sleep/standby?
i have it setup to 324/224 standby, but i dont really know if the phone is going to those clock speeds as soon as its on standby.

I have a few apps that sync, such as Pure Calendar / Messenger but nothing that should drain it that quickly. I hadn't installed any new apps and never had this occur, so maybe it's a bug where something caused the CPU to run at full overnight. I'll leave it unplugged tonight too and see what happens.
I think its bln, I had it on at night and it would stay blinking the whole night while I was sleeping from texts. Happened every night until I turned off bln at night and my android os usage went back to normal. Just my thoughts

If you have it set to blink, it will use a ton of battery. If it just turns on and stays on it uses less.
Since our lights don't actually blink, they had to tell it to turn on, then to turn off, then to turn on, then to turn off....etc. The phone can't sleep if it is always trying to do something (like turn the lights off and on).

Well on my epic its high because I believe AOSP has the problem in accurately getting stats with percentage. Because on my epic when it used to ran TW it was more accurate.
Sent from my SPH-D700 using xda premium
So for users with Android os being high, it could be cuz of the bln?
Got a weird problem with my AT&T stock non-rooted S4. About 4 or 5 times since I got it on release day when I charge my phone and I get the notification that it's fully charged the screen won't turn back off. I use a Belkin Conserve socket that is set to shut off after 3 hours and I've woken up after charging to find the phone dead. I've managed to catch this happen once and when the fully charged notification comes on the screen won't go to sleep, it just stays on and flickers a little bit. For all but one of these instances I had blocking mode on so I'm not disturbed by email or text notifications in the middle of the night. It did happen one time when I didn't have blocking mode on. I use a pin lock for my lockscreen and usually have BeyondPod playing overnight (only one hour long podcast while it's still charging) if that makes a difference. Is the function that enables the screen to stay on when you're looking at it malfunctioning? Any help? I've attached two screenshots of battery life when this happens.

So in settings under the Developer Options, there is a setting "Stay awake" if checked screen will never sleep while charging. Now I see that your Belkin shuts off the power but your phones still detects the usb plugged into a power source.
I think things happen in this order: you hookup your phone to charge and shut off your screen, phone charges to 100% and screen lights up saying fully charged, it stays on because of that setting, Belkin kills the power, it is still hooked up to USB so ... you get the rest.
I would find that setting and disable it.
if your next question is "I don't see developers option" it is hidden by default in android 4.2.2 so to make it available, go to Settings > About phone and tap tap tap Build number seven times. Return to the previous screen to find Developer options. Or Indiana Jones might pop up and give you the cup to get eternal life !!!
Thanks for the reply Commodore64 but I already checked that setting when it happened the first time and it's not checked.
No one else has had this problem?

I have this problem as well as my wife's S4. around 3am, I notice our room is bright with our two phones' screens on. It will stay on until the morning.
In the developer's section of the settings, the stay on when plugged in is NOT checked.
Also, on our phones, we notice the phones overheating because the screen is on for hours at a time at night.
I've just spent an hour looking through the internet, and while many report this, they are simply being dismissed by others as in having "checked" the setting in developer section.
Also, when the batttery does get fully charged, the "Battery if full, unplug the power" notification also rings the default notification ringtone. I've installed phoneweaver to set my phone to no sound overnight, but it only stops the sound, the screen still stays on and phone gets really hot.
This is turning out to be a huge problem for us.

Do you use a PIN (number) lock? I did but switched to the pattern unlock and it hasn't happened since. Also, I've been trying to charge only during the day or evening, not overnight. Maybe, since I charge during the day and I use it periodically while it charges it doesn't go into a "deep sleep" like it would if it charges while sleeping and the full charge notification would keep it awake. I don't know exactly why but it hasn't happened since. Hope this helps.
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.
Hello everyone,
Since my S4 is on 4.4.2, it's always awake when the screen is on, even if I'm not using any apps, which wasn't the case before the update. I'm rooted and used BetterBatteryStats, but I can't find any processes or wakelocks causing it. Screen-on time is pretty bad. Does anyone have an idea how to fix this?
Factory reset didn't help.
Thanks!
Come on...Is this really the skill level of XDA now?
If your screen is on, then your phone is awake. How should it display anything on the screen while your phone is sleeping?
Your screen on time is perfectly normal.
Be easy man I saw this problem few times, he is talking right but I dont have a solution

No, awake means the phone is actively doing something. Before the update, I've browsed websites for hours without the phone being awake at all.
For example, the stats of a GSG4 Mini on 4.3:

No you didn't.
The battery stats screen might have been saying that, but it was a reporting error by the stats monitor. You absolutely positively under no circumstances were browsing the web without the phone being awake.
Also your battery stats screens are not showing that the screen is on constantly. It's showing that your WIFI is on constantly.
I don't think WIFI is the problem here. With the screenshots I just wanted to show that the phone is awake (and using relatively much power) as soon as the screen is turned on, and doesn't stop until it's off. On the mini/before the update the phone wasn't constantly awake while the screen was on, as shown in the previous screenshot.
Any ideas how to stop it? Or is this just a quirk of KitKat? I'd be glad if someone could check their battery stats on their device.

Dude, your other phone was awake when the screen was on. Period.
All phones are awake when the screen it on. Period.
It doesn't matter what battery stats or monitors say. If they said the phone was asleep while the screen was on and while you were actively using it, the stats were wrong.
If the screen is on, the phone is awake and the processor is processing stuff. There is no grey area here. There is no possible way a phone's screen it on and its displaying an image without the processor being awake and active. It's physically impossible.
