[Q] Battery drain in deep sleep

Hello,
I am asking this question as to confirm if my tablet needs to be sent to warranty or this is a normal behavior to you other people reading this post.
I have stock 4.2.1 rooted on a nexus 7 16gb version
When I lock the screen the device enters deep sleep => I can verify this by using CPU Spy, it says that in 30min of screen off, 28 minutes were spent in deep sleep
Using Battery monitor widget with refresh rate at 1min I can look at the log and see that the tablet had a constant drain of 50 to 94 mah during those 30 minutes. Only after 2-3 hours the device starts to have a drain of 2-3 mah (if the screen is off)
Wireless, Bluetooth, Gps are turned off.
If you think I may have omitted some things in my test procedure please share some info, otherwise please tell me if you also encounter this problem
A good day !

background apps could cause drain, not even apps you opened. like the facebook app is notorious for it.

Hmm, normally when I had the HTC HD2 when it was in deep sleep it had a drain of 2-3mah - battery monitor widget was checking every 1min
Now with the Nexus 7 the drain is 50-94 in deep sleep, do you think this would be a normal behavior ?

I can relate
I get the same type of behavior on my Nexus 7 16GB wifi only model. Mine does not seem to be due to an app either, as the main battery use is Google related (Play store, or Google services, etc.). Take today for example. I charged my Nexus 7 overnight, verified that it was reporting fully charged when I got up, then I put it to sleep and set it aside to take to work and didn't use it again. When I got to work 2.5 hours later I turned it on and it was at about 83% battery. I lost almost 20% battery in 2.5 hours without even using the tablet. I attached a screenshot - today's culprit was Android OS (I took the screenshot a couple of hours later at work). This behavior started after upgrading to 4.2 - it never did this on 4.1.
Oddly enough, I don't get this type of drain if there's no wifi connection, even if wifi is left on and there's a wifi signal that it's just not connected to. When I get someplace with wifi, the battery drain starts again.

Severe Battery Drain from "Android OS"

Anyone else having this problem? All the sudden Android OS is taking a ton of battery, killed half my battery overnight while the screen was off. Anyone have any of these problems?

Android OS is too general to say what is causing the wakelock. Use an app that can see which process is causing the wakelock directly and you will know what the problem is.

My android os consumes 70% of my battery. Tried better battery stats, but I don't see any wake locks

Then you definitley have an app or two that is causing it. Try CPU Spy (let's you know if you get deep sleep or not) and see if that helps any. I hate battery drain so best of luck in solving your battery drain issue.

Since I've upgraded to 4.2 roms on all my devices I've noticed this too. Normally, Maps is the culprit causing a "normal" wakelock. Google +, Latitude, Google Now, etc. This is just the way Google operates now & the biggest difference between 4.1 & 4.2. I've taken to disabling Location unless I'm needing GPS service. It checks your location every couple minutes it seems.
I've had a situation you describe a few times caused by media storage. It keeps scanning the SD card. Sometimes a reboot helps but mostly I've just changed roms instead of chasing it. Better Batt Stats should show it somewhere. Keep looking, look in "alarms". Also you might try GSam Battery Monitor. That app has come a long way lately & also helps finding battery sucking sources.

For me it was Viber. After deleting it I get almost no battery drain over night. Maybe 1% in 8 hours...

Excessive Deep Sleep Battery Drain

Some of you may have noticed that battery life on this phone can be both unbelievable and mediocre. I've been trying to figure out what can trigger and cause mediocre performance and I'm at a loss. The problem is, there doesn't appear to be a smoking gun. No obvious wake locks. No rogue Apps. I have Carrier IQ disabled by System Tuner. Google Now is off. What I'm running right now is pretty bare bones. And the kicker is my phone is sleeping, as can be seen in the shots below. The vast majority of the time my phone was off the charger it was in deep sleep mode.
I noticed my phone in excessive drain mode Saturday so I let it run over night and into the next day, so that BBS and GSam could pick up as much data as possible, including sitting idle overnight and very little use throughout yesterday.
Here are some shots to show the story. The graph, which is definitely steeper than when idle drain is normal, which resulted in idle drain of about 6% per hour. Also as can be seen in these shots, there is not a wakelock problem. Deep sleep shows as 12 hours 38 minutes, Awake time of 1 hour 8 minutes, and screen on time of 1 hour. So, my phone was only "awake" for 8 minutes when the screen was off out of almost 14 hours according to BBS.
I did notice and oddity here though. BBS listed the unplugged status as 13 hours 47 minutes, while the phone's battery meter listed it at 12 hours 13 minutes.
Attached are the shots I took at 19%, as well as a final battery meter shot after charging the phone to full while powered off and restarting, where it's been purring like a kitten in deep sleep.
Part of me is beginning to believe there is a bug with the battery gauge. What do you guys think is going on?

Try clearing data for google play services,google services framework and playsore than reboot and check if things changed.
And i would recommend uninstall the updates related to those apps and let them update itself again.

Done. Although I won't know if any attempts to resolve the issue have worked until the idle drain triggers again (or doesn't).
Thanks for the advice.

Well unfortunately that didn't solve the issue. The heavy deep sleep drain again triggered after a bit over one full day. I charged to full last night and let sit over night where it drained 6% per hour with no obvious culprit. Anyone else have any suggestions?

It seem that your signal is week, did you get stable signal and have you tried airplane mode, to find out how much battery drain in this mode?
Also, did you disable LG MLT? This is a massive app from LG, can consumed about 150 MB RAM.

This might sound boneheaded, but what about just resetting the phone. Maybe some system app is causing some type of memory leak and thus draining your battery. Also disable wifi when you're not using it.

I don't think it's signal related. I get an excellent signal at work and the idle drain still occurs. Also, it happens whether wifi is on or not. I have not disabled MLT, as I'm not concerned about RAM, just running processes. Rebooting the phone eliminates the issue, so something is obviously getting hung. The really odd thing is I was draining 6%/hr overnight, all while the phone was in deep sleep, yet my top battery consuming category was the screen at 35%, with just 1 hour of screen on time of 10 hours off the charger. If something was cranking in Android System that caused 40% drain overnight I would have expected Android System to be higher. It doesn't make any sense.
I may just have to factory reset.

My battery's been great until couple of days ago when I turned on GPS and Voice Notification (for speaking out names when phone call/message comes in). After I noticed the abnormal battery drain, I turned off those two options, because that's the only thing I did differently before noticing the drain. However, that didn't help... yet. I needed to do a reboot and battery's been fine again. Not sure if those two were the actual culprit, or just coincidence.
Have you changed any settings right before you noticed the drain? Just a thought.

had the same issue., wakelock detector, BBS, GSAM nothing could show what was eating the battery. i use mobile browsing a lot and almost 8/10 times this battery drain was happening with chrome , chrome beta and firefox browsers.
Only thing thats helping me is the Greenify app . Greenified the chrome and firefox and almost all the cloud apps and the battery is now much much better.
still ...IT IS AN PROBLEM to be found..

To provide a bit more info on this, attached is a pic of my reboot a couple hours ago (marked by the thin white vertical line). The change in the slope of the drainage line is drastic. Also, notice the small hump after the reboot? The line actually increased a bit, fell, then flat lined. More and more I'm beginning to suspect the battery gauge, but I just don't know.

I have the same situation after charging. Even in"deep sleep" it would chew through the battery. Now I just reboot the phone after charging and it plays nice. The gerbil on the wheel seems to take a break and rest.

To all who have excessive battery drain, did you charge your phone while it is on or off?
Some where in this forum (if not mistaken), I read that there is a bug while charging G2 when it is on. You should reboot your phone after it is fully charged otherwise you will experience excessive battery drain.
Mine always charged it while it is off and never had problem with battery life.

i got the same issue which is very annoying, have over 85% deep sleep, no wake lock, battery draining like crazy, and it happens randomly. I wonder if factory rest fixes the problem, or hardware issue
i have done a bit testing for this random drain,
with mobile signal on ==> huge drain
without mobile signal on and only phone signal ==> huge drain
airplane mode ==> no drain
so i believe it is a bug within the phone software, actually sometimes the random drain started after a phone call

I've been getting the drain too in the past few days. Last time i could fix it by factory resetting, but obviously I don't feel like doing that once per month. What I do know is that flashing another stock ROM (kdz) without factory resetting doesn't fix it. However last night I figured i'd try disabling WiFi (kept it on during the night until now) and I only drained 1% in 5 hours, down from 3% per hour. Perhaps this bug is related to WiFi.

Have you disabled LG MLT? It acts like CIQ for internal LG purposes. I have personally seen it cause mass wakelock in unexplained situations. If I leave everything on overnight under 95% battery, I will get around a 3% drain in about 7 hours. Pretty normal. The first 5% on these batteries seem magical. At 100%, with everything on, I wake to 100%.

Yup, frozen in TiBu. Will be factory resetting however when I get home as GSAM grabbed my attention. Never were system things so high up the list when i had no drain.

I been struggling with this since I got the phone (almost a month now). I've done all the usual:
Removing bloat
Disabled CIQ
Disabled Google Now, Location, GPS
and I have the same apps as my Nexus 5
Just last night I realized that this battery drain only happens after taking it off the charger. This got me to add the word "charging" in my search and I found this thread.
Is this hardware related, or would a custom ROM resolve this? I have the AT&T version.

Ok and which stock rom does not do that?

SM-N9005 4.4.2 Battery Issue

hoping to get some help...
i have update my SM-N9005 from 4.3 to 4.4.2 through Odin. rooted. with CWM Recovery.
tried probably 3 custom ROM that support 4.4.2 and end up on the Official leaked.Build 4.4.2 ( rooted)
the battery performance is driving me crazy.
on 4.3 stand By mode i used to loose 0.8 per hour now with the same setting same features turned on. i loose 2.3 percent per hour.
on 4.3 screen time with the lowest Brightness i lost 1 percent every 10 minutes. now i loose 3% with same brightness level. 3 percent every 10 minutes.
Android OS and Android System are always on top of screen in the battery Graph. i
media is also on top of the screen in the battery graph.
have tried a lot of solutions and factory reset with no luck at all. ( i have placed the device with Airplane mode with no SUCCESS )
installed a lot of battery analyzer apps did not have a clue who's eating all the Juice.....
any idea how to fix this??

Partial Wakelocks are usually caused by apps running in the foreground. There's usually not much you can do about that. If you are actually using the phone, battery will run out. What you need to find out is what happens when you are not using the phone.
Do this:
1) Charge the phone to 100%. Disconnect the cable.
2) Let the phone sit idle for 1-2 hours with screen off.
3) Get Kernel Wakelocks from Better Battery Stats.
Then you'll know what's eating your battery when you are not actually using the phone.
In my case, I get ril-fd, l2-hsic and wlan_rx_wake wakelocks the most. I know the causes, but I can't do anything about them without rooting.

I've noticed the first 10 percent (from 100 to 90) go away fast as hell. Use your phone as you would today, just make sure you have enough juice by the end of the day. Leave it as it is overnight and then post your screenshots.. You don't seem to have any wakelocks so your battery shouldn't be draining.. Mine is going like 1% for 8 hours or something, the problem starts when I turn me screen on lol!

I had this problem on my all my Samsung device
the only solution was to take out the battery for a few seconds

i am loosing more than1.5% per hour where on stand by mode... everything is switched of.f im surprised there is no wakelocks showing... ill wait till the end of the day.
its been 4 hour since last charge and now im on 93%..
im assuming the drain is happening due to the bad reception where i am at.
how do you manage 1% per 8 hours that's Awesome (knock on wood) :laugh: .. is this with WIFI and Data on?

i don't understand ... how come i have no wakelock after screen off.. and my battery draining 1.5 % per hour on stand by mode.... and android Os always on top ?

BBM.
And I haven't done anything special, actually you have to do something to NOT get great battery life while idle. After a factory reset, nothing disabled (so G+, G search and all those wake cycles still present) with WiFi off and Mobile Data ON I lost the usual 1 to 2% per 8 hour sleep. The problem starts for me when I turn on my screen, not when it's turned off

It's caused by broadcast packets sent by other devices in your network waking the phone up. The solution is to install a custom kernel that filters such packets.

Massive wake lock and battery drain

Hi guys,
I have been having an issue with my Motorola X Play (UK Single Sim) I have only owned it for a few months from new.... The battery is draining fast and I can see in the battery stats that it's not sleeping, otherwise the battery usage page shows nothing of interest, apart from perhaps Mobile Standby which is quite high, above the screen but the signal bar is all green...
I rooted my phone to better find out what was causing these issues, otherwise stock Marshmallow. Unfortunately Motorola now are not interested as they say my phone is rooted and now has no warranty - useless idiots!
Using GS Sam battery monitor (rooted) I can see that the following is keeping the phone awake, no other app is.
48.3% of battery consumed by Kernel (Android OS)
Keep awake over 2 hours
CPU usage 59m 53s
Number of Wake Locks: 1
Byes sent: 246.21KB
Bytes Received: 5.70MB
App UID: 0
Wakelock Detail:
Google_C2DM 0.0s (1)
I have tried safe mode but it appears to be the same, I have hardly any apps installed apart from Facebook and Facebook messenger and I have even tried it without them...
I have tried turning off/on WiFi / Location / GPS is now disabled. WiFi Scanning is off. Restarts make no difference... I have even done a factory reset about a month ago.
Any ideas, this phone is having the same battery life or less than my Nexus 5 which had a much smaller battery...
Many thanks

here's a way to avoid it http://forum.xda-developers.com/galaxy-s2/help/google-c2dm-checkin-services-t1321520
i'll update if i find anything else.
don't tell them your device is rooted. if you go to service center just re-lock the bootloader and its back to normal.[it won't get your warranty back but they don't check that much]
can you post a screenshot of gs sam.

1 - Install BetterBatteryStats (BBS) - this will give you detailed information on what is draining your battery. Get it from XDA v2.2.0.0B6 - this gives you the detailed breakdown in the UI that you are after, the google play version doesn't do it in the UI (older version).
Get baseline results (charge it full, don't touch it for 5-6 hours) I like to do this while sleeping.
2 - Install Greenify (you don't need the Xposed module if you don't want to fiddle with that yet, alto I highly recommend it) set the working mode to root. If applications are still not sleeping, add the widget and force sleep everything before you turn off your screen
Get BBS results (do the 5-6 hours while sleeping) - improved?
3 - Install Naptime from the google play store (by Fransico Franco)
Get BBS results - improved?
Getting anal about battery usage?
4- Read up on Amplify - this yielded even more results for me. But this can take a bit of work to get right. There's a lot of great threads on XDA for setting this up.
5 -Smart network - allows you to control data, networks, wifi, bluetooh, nfc, gps on/off with a ton of great features for auto. management.
I have all the above and yield a 0.4%/hr drain on stand by (see signature for phone build).

Amplify is a god sent app. It has been 4 hours now, and I have been using whatsapp on and off (about 20 seconds each time) and I still have 97% left in the tank.

Facebook app has been known to cause serious battery drain in the past. Uninstall it and test again.
In 99% of the cases it is caused by an app. Try to find out which one is causing the drain.

Hi all,
Sorry for the delay and thanks for the replies. I performed a factory reset again, after clearing the cache etc, the same as I did last time. The only difference is I then installed Android 6.0.1
The battery drain has now gone. I didn't perform a restore of apps etc, and the only apps I have installed so far in addition have been Facebook and Facebook messenger but I have found these have had no effect at all on the battery drain. I haven't even updated the stock apps (apart from the security ones).
I now get two days of use easy. It also seems to be running slightly faster. I will update apps one by one, over the course of a few days to make sure nothing causes it again...

http://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884
I use this guide, works really great to limit wake locks.
And I don't use Fb app but use the browser instead, battery lasts easily two days of "heavy" usage !

I found the problem, or at least a major bug. Whenever you cast to Google Chromecast Audio and then stop casting completely there is a massive wakelock until you next restart the phone. My phone was awake all night and down to 20% battery life. Android OS takes a massive portion of the battery life and under keep awake stats it's 9 hours +. It seems that when it says disconnected it is not. A major bug! I'll try and report it using Google's bug reporter...

not even Doze could kill it? perhaps you could try Servicely and see if it could stop the thing from running.

Nope, Doze had no affect at all but it should be as it was sitting stationary overnight - normally the drain overnight is a few percent at the most, last night it was around 65% and I was left with 20% in the morning and this was I think the first time I had used Google Chromecast Audio since the factory reset with great battery life up to last night... I could try Servicely but I am not sure on the service to kill and I'd like to keep it 100% stock for now so I can help out Google to fix the bug (or Motorola if they bother)... What a pain as I just bought 4x Google Chromecast Audios!!
I have reported it here in the Android bug tracker, feel free to comment / star the issue to bring it to Google's attention.
https://code.google.com/p/android/issues/detail?id=208324
However I am not sure if this is a Motorola Issue or a Google Marshmallow / Chromecast issue?? Motorola support have been very unhelpful so no luck if that is the case...
If anyone else with Chromecast Audio could confirm the bug that would be great.
Thanks
Laurence

There's a post on reddit about battery drain with chromecast audio about a year ago, not sure if it's the same issue though.
