Battery Drain, almost solved. Need help from Dev.

Hello Everyone.
There is a battery drain issue in in cell standby and I think I just solved the issue. Let me go back to when I last experienced such an issue. It was when I flashed a ROM for my SGS1 Captivate called Cognition. There was a bug that left wifi not only on but it was active during sleep mode.
http://forum.xda-developers.com/showthread.php?p=12294219
It was later solved by the Dev and the draining went away.
What is different here is that the SGS3 only has this bug when wifi is on. Look at my battery charts when I have wifi on and wifi off. The red area shows the slope with wifi and the blue area shows it without wifi. This is during standby times.
So is this due to the wifi dual banding just taking up more battery? Or is the phone not properly tuning the wifi down in standby? Solving this issue is out of my hands now and I will have to hand this over to someone else.
For now, change your wi-fi sleep policy to shut off when in sleep mode.
EDIT:
So I think i figured out why the wakelocks are happening. Other people have the problem with dynamic IP addresses.

I don't know why these other fanboy war threads are bumping and so popular but a serious problem doesn't even get a response or a second look. Does anyone else have any comments on how we can get this fix? We need Samsung to fix this problem too.

I will make this post for two reasons;
To bump the topic
To say that i would also like this "bug" to be solved

hi slim,
I agree with you here as well. However I've not noticed any battery drain. I've got about 35% left after good full day of use.

I'm experiencing some kind of battery drain too with sgs3, but mine it's not wifi related. I have as first voice in battery stats page Cellular Standby. I mean, it's almost impossible it drains more then the screen!
Anyway, giving a look at your screenshot, I can clearly see some areas you didn't red boxed when wifi was on, screen was off but battery drain was not terrible at all.
How do you explain them?!
Looking at your screenshot

Yeah, I mean my battery life is still good, but I know it can be better. Now that I made it turn wifi off when it's asleep the battery life, the slope you can see there in blue, is a lot better. It's not so slanted and draining as quickly.
A lot of other people that complained about bad battery life I noticed the same trend, it's their wi-fi also. If you notice the long blue line on the bottom, that's when wi-fi is active and those extreme slopes have to be caused by wifi. Cell standby shouldn't be draining the battery more than the screen I don't think.
It's either wi-fi, the radio or both.

I don't know, I guess that is when the wifi properly shuts itself off.
When I look at my screen while I'm not doing anything at all I can see the orange arrow on the wifi on, and it stays on even though I'm not using the internet or anything. What can that mean? Is the orange arrow "uploading" or "downloading?"
EDIT: It's downloading. And I set the wifi to shut off if the screen shuts off. The Wifi sometimes shuts off. But right now it refuses to turn off even in sleep! And the orange arrow is lit up!

How do you get the wifi to shut off when the screen shuts off?

It's there in advanced wifi settings.
Did any of you people tried flashing different modems to resolve this?

If you turn off the wifi then wont it just use the normal data connection and so use more battery? I was led to believe that using wifi was less demanding than say 3g.

Yes that is correct, but read my OP and the thread I posted. A wifi bug is the wifi not powering down in sleep mode. It stays on at full power during sleep and drains your phone.

Just a thought. Dont all phones stay conne ted wifi while the screen is locked?

No, some turn off the wifi radio if the phone goes to sleep

I tried a couple of modems, but in vain. Cell Standby is always much too high. Wifi is beyond good and evil.
I would by now also lean towards a bug. Unfortunately I'm not a Android dev. My knowledge ends at developing apps.

I am satisfied with mine

ive noticed smth:
with Droidwall blocking everything -> still wlan sends smth & causes traffic
hows that possible? u guys can experience the same?
under 3g/edge and droidwall everything blocked: no traffic anymore -> everything is ok!

Have any of you guys tried easy battery saver? One of the features is to disable radios when screen is off. I wonder if it is more successful in doing this than the built in setting.

I got the same cell standby problem so I went ahead and flashed Omega ROM, yesterday was my first day full with that ROM and the result was quite good. I ended up with about 45% battery after about 15-16 hours. Well I'm on wifi for like 3-4 hours though.

Drain caused by exchange sync process. Kill this process and see how battery life will change. Sorry for my english.

Curious, which F/W are you on? I was getting oddball WIFI battery drain using an older LE9 insecure kernel to root at first (WIFI would actually shut off and come back on after coming out of idle... even though I had it set to "always on.")
Completely went away after I flashed back the stock LEF kernel that my phone shipped with.
For reference below, no drain issues during idle with WIFI left "always on."

[Q] Nexus 4 battery drain while device is sleeping

Hi,
I have a new Nexus 4.
Sometimes when I check my device in the morning, I see that it lost ~40% at night.
This happens even if I turn off wifi and mobile data.
When I look at the battery settings I see that the device was sleeping the whole night.
So if the device is sleeping and there were no wake locks, what else can cause him to loose battery?
Thanks.

FB-Messenger, Skype, WhatsAPP to name a few candidates.
Try the cpuspy AP, this will tell you in which activity staus your phone is in and how long it is in deep sleep e.g.

Thanks, I installed CPU Spy.
Seems like 46% was in deep sleep and 44% in a low frequency (384 MHz).
So how can I tell what caused it to get out of deep sleep?

Only one example is the monitor included in Android Assistant (useful APP in general IMO)

"Report location from this device" was the culprit in my case. Caused massive battery drain even when everything else was turned off.

No deep sleep - PowerManagerService.wakelocks

I recently started to get a problem on my nexus 4. After some days of uptime my phone refuses to go to deep sleep.
BBS report PowerManagerService.wakelocks using 98-99% of battery.
I have tried to turn off data, change from 3G to 2G, turn on flight mode, disable nfc, close all running apps and so on but the wakelock remains. Nothing but a reboot seems to help. Does anyone have an idea why this is happen? I'm on stock 4.3 unrooted.

PowerManagerService.wakelocks is just a placeholder for the partial wakelocks.
Check in the Partial wakelocks tab to find out whats causing this problem!
It probably is something related to AudioOut_x , which is caused by touch sounds or vibrations.

No, partial wakelocks doesn't show anything unusual. The link that was posted above was spot on. Both my and my girlfriend's n4 has recently started to show this"bug" :/

I experience this issue with my Nexus 5 and is an Audio In partial wakelock credited to Google Quick Search. Otherwise NOW!

WiFi killing battery?

Lately my battery just drops every 5 minutes. The phone is new. So I decided to try something. I turned my wife off last night and my battery only dropped one percent. So it seems wifi is using resources. Is there anything I can do to solve this? I am using a stock untouched phone.
P. S how come the Sub-Forum section is so cluttered and not alphabetical order? Finding the phones correct forum is a real pita.

I suggest to download Wifi traffic monitor app like this one https://play.google.com/store/apps/details?id=vn.wada.trafmeter or anything similar, to see what app is using wifi the most. You also can save battery by set wifi to never scan and never wake when screen is off. This will prevent any apps from using wifi while your screen is turnoff.

OK so my top app is chrome/Google. That doesn't make sense.... Because the phone drains fast when screen is off and wifi is on. I don't have unlimited data so I always keep that one off.

You need to set wifi "Keep Wi-Fi on during sleep" to NEVER and "Always allow scanning" unchecked.

Deep sleep issue

I have latest rr rom installed and at night it does not go into deep sleep. I think on other roms a have same problem.

Here is screenshot from cpu spy plus

Now i have Deep sleep on cpu info but my battery still drain a lot during night: it is 30% less any idea? I have franco kernel on rr

I noticed this too, about 20% overnight, nearly on every custom rom. I will turn off the ambient gestures this night, let's see if it gets better. Always on display is off anyway, that should be clear.

Use ForceDoze app to put the device to sleep as soon as you turn the screen OFF.

my ambient gestures is disable.

deep sleep = doze, enter when no sensor cath anything, if you keep night your phone somewhere the sensor feel movements, for exsample, the phone will not enter doze.
use an app for force doze, can work even with no root applying 2 adb command, like naptime, greenify and so on.

No, its your rom/kernel problem, i'm on "other rom" and i dont have this issue, standby only drain 1-3% over night.

Lastest Carbon with inbuilt kernel.

Problem is not with rom nor kernel. There is a problem in the USB port i also have this problem. There is a temporary fix. Not a permanent one.
The temp fix is you need a root browser with root permissions
Go to /sys/module/dwm_msc (or something like that) /parameters then click on the file disable_host_mode and change the value from N to Y
If phone is restarted the value gets reset to N

OK, i changed it, let's see what's happens.
 @GVN.Gallus could you check the value on carbon ROM ?

I had the same issue with stock rom. Naptime did the trick for me. Before that IT wouldnt go info deep sleep.

Using Naptime during night still drain a lot battery ... Help me :|
Edit:
During night my phone is always on deep sleep. i checked it with cpu spy plus.

It is normal? Screens from wakelock detector.
100%-75% after 3 hours with 40 min SOT. ROM:Aosp extended with inbuild kernel

Everything look ok to me, BUT one app
I think Google Play Services causing you drain, on my stock ROM, Play Services is least active app while on you screenshot it is most active one. Try to, disable, enable and then update it.
