No deep sleep -> how to identify the cause?

Hey guys --
I did a search and while there is much discussion of deep sleep problems, there is no clear way I could easily find to identify the cause.
I have CM7.20, the MiRaGe latest build on my NC, with the settings listed in my thread (see the sig). Recently I noticed that it is not entering into deep sleep, indicated by losing ~20% battery while it is asleep overnight in about 8 hrs. Battery results tell me it's "WiFi" taking like 30% of the battery, which seems quite odd, since I had it set to turn off WiFi while the screen off unless connected to the charger.
Any clues on how to identify the problem with deep sleep?
As for usage, I am using my NC 99% of the time with the following apps:
Moon+ Reader (probably 70% of time)
YouVersion Bible app (most of the rest of the time)
Dolphin Browser HD (maybe 2% of the time)
Enhanced Email and MailDroid - very occasionally but they are checking mail on 15 min intervals when wifi is on.
I have a ton of other apps installed but I almost never use them except for these.
Any help on how to determine what is causing the NC to not go into deep sleep will be immensely helpful. I have a 2-week Euro business trip coming up next month and I would really like to solve this before then.
Thanks!

Better Battery Stats might help. Try turning off sync before bed and see if you still lose 20%. If so, it's definitely some app that's the culprit. Grab something that will tell you what program is using data and how much/how often and you should be able to isolate it pretty quick.

OK, but it should be turning off wifi, and therefore sync for ALL apps, when it is asleep. Can an app override this setting? That's my guess, is some app is doing this. How can I ID that?

Like envygreen said use that app to track wakelocks. Even if wifi is off, some app may be applying a wakelock to try to sync.

Alright, I'm on it

So last night I finished charging it and read for a couple of minutes, then put it to sleep to see how it went overnight.
My Wi-Fi sleep policy is set to turn off wifi when the display is off.
When I got up this morning I checked it and it had lost over 10% battery over night, and I checked BetterBatteryStats and I think it is going into deep sleep but maybe not shutting off wifi.
I have attached the screenshots from BetterBatteryStats, and I think I need help interpreting them and finding the cause.

ok, so here I am replying to my own thread... If I am reading this right it seems to be looking like my wifi is on the entire time, not only when the screen is on. Is this the right way to read this? In this case, it looks like "Wi-Fi sleep policy" being set to "When screen turns off" is not actually working... right?

It sure looks that way to me too. It says wifi on 8 hours. Did you try toggling the setting a few times? Also you are on Mirage and he may have done something in his tinkering that messed that setting up.

yeah I did toggle the setting on and off, and in fact before I had it set to "On during sleep if plugged" for a long time, recently changed it, thinking maybe this was the cause.
But it does appear that maybe this is what is killing the battery. There doesn't appear to be any network activity when the screen is off, just looks like the wifi radio is powered up.
Any advice?

Hmm. that seems like an extreme step, but maybe ... wonder how much of the snappiness I will lose.
EDIT: OK I switched to CM7.2 stable. Nice I didn't seem to lose any settings. Let's see how it goes. Thanks for the advice, I'll report back here if it still does the same thing.
Also uninstalled beautiful widgets... figured maybe that could be causing an issue.
Oh, and I probably had a SOD kernel patch applied... perhaps that was the problem too
guess I should change only one variable at a time for a good test, but in reality I just want to get it fixed and not really diagnose it.

I was having a similar problem...what I did was run the V6 supercharger script, granted i am running CM9 atm but it took care of any problems I had with battery life and wifi signal.

Question: does having WiFi on keep the phone from going into deep sleep at all?
I have found that my phone is not going into deep sleep. I checked what is holding wake locks, and the time with wake locks is way less than the time the phone has the screen off, so it appears it is not deep sleeping, even though there are not wake locks.
I have an extended battery, so I get good battery life, but always interested in improving it. But I also have this thought that if I have to turn everything off, and only synch when I turn the screen on, that is not ideal either.

Get CpuSpy free on play store. It will tell you exactly how much deep sleep you are getting.
Having wifi on all the time should not prevent deep sleep. Only when things use it does it come out of deep sleep.

I have CPUSpy Free, and that is how I know I am not getting deep sleep. My challenge now is to identify why.

OK, so it seems that CM7.20 stable definitely fixes things. I didn't flash the SOD fix, so maybe the SOD fix was preventing deep sleep before, or maybe something else in the kang build was preventing deep sleep with wifi on when the screen is on.
However the better battery stats still seems to say my wifi is never actually going off. I am not sure I am interpreting the results correctly. It looks like the wifi is on all the time even though it's set to turn off when the screen is off. But I can let the NC sit on my night stand overnight and lose only a couple of % where it was like 10+% before. I still think my problem was due to some app that updated and not the ROM because the problem started weeks after I last updated the ROM.

MSM_HSIC_HOST Wakelock. Suggestions on how to fix?

I have no idea how to get to the bottom of this. Everything I normally try simply doesn't work when it comes to fixing this problem. In Better Battery Stats, it's clear that something is causing the modem to stay awake, because msm_hsic_host is a direct reference to external modem. I will literally have 10-20 minutes max of partial wakelock from sync and then I will have over two hours of msm_hsic_host wakelocks. Avast and Better Battery Stats all do not show any application taking up significant data in the background.
This is making the difference between 4-5 hours of screen on time and 6-7 hours of screen on time. Is there some sort of method to figuring out what is destroying my battery life?

Don't know if this information will help, I have used wakelock detector from play, a free app to show various wake locks .
Also tried Qualcomm battery guru, again free from play , it's a beta app specifically for phone with Snapdragon soc. When first enabled it monitors your phone usage for over 24 hours before enabling various power saving options, that can be customized by the user.

hmm.. interesting to see this as i thought this was a 4.2 issue. See this thread below. The wakelock is related to a driver issue from qualcom who makes the snapdragon s4 pro and 600. They released a patch that has been merged into various custom kernels but the issue remains in the AOSP stock kernel to this day. This is a main reason why i dont mind being on 4.1.2 instead of 4.2.2 until google or a dev for the HTC one fixes it, your battery life will suffer
http://forum.xda-developers.com/showthread.php?p=34858556

I ran a wireshark to figure out what was causing it.
One of my issues was Hotmail sync. Setting it to Push apparently means that it will constantly send packets back and forth. Stupid, but whatever.

Hey,
can you explain how you ran a wireshark? I have this wakelock and can't figure out how to stop it and I dont use hotmail sync

Same problem here.... Lot of wake locks and can't find out what causes it.
24% lost in 9 hours sleep mode.

I have the same problem. Because of this Wakelock my HTC One won't go back to DeepSleep.
Is there no app/tool to observe which ap causes this wakelock?

did anyone find a solution? which network are you on (i'm on vodafone nl)

Facebook messenger!
I had this issue as well.. the wakelock was doing its thing like 50% of the time.. removed facebook messenger => the values are back to normal.
Please post if you can see the same..

Here's a really good explanation on what this wakelock is and how it's being produced.

It's apparently much better than the n4 which had nearly the same wake lock as off-charger time. The snapdragon 600 with HTC has much improved the wake lock times.

i woke up today to see this happen for the firs time to my phone.
newest changes to mine: installed ARHD 9 (but it was fine the day or two since, only last night it was unplugged from the wall, instead of the usb port)

SnapDragon battery guru

This might seem like a question but its not.
Personally what is your opinion on the snapdragon battery guru? Like does it help you out at all?
Any comments on it? I Tried it on my HTC before i broke it (had it for 2 months lmfao) and it was in learning mode and started doing crazy stuff to my phone like turning things on and off and it got annoying but im thinking of using it now since my htc got like 16 hours of battery and i only get about half of that now even after tweaking everything.

Im currently not using it but yes it does help a bit

In my experience it wakelocked my device quite a lot, especially if you move around too much (work, travel). It's whole operation is based on user location, so it has to wake your phone to fetch location and do whatever it needs to do. In the it was a ****ton of wakelocks.
Your experience may vary, try it out yourself and monitor it with wakelock detector.

thanks to the wifi problem that comes with kitkat i have to keep my location on "device only" and the app keeps asking for 'location services required'

It Helps
I have been using it for months now. It does help with battery life. I like how it automatically refreshes apps based on usage. I have tons of apps but very few i want to refresh automatically. The low power mode is nice to get the most out of my remaining battery without me having to turn off everything and dim the screen manually.

Battery life suddenly dropped and phone is always warm - How do I diagnose problem?

I searched and haven't found any battery life thread quite like the problem I am having.
I got my Nexus 6 new last September and until recently the battery has always lasted all day for me. I never looked at battery stats or tried to optimize because I never needed to. About a week ago, the battery started running out by 3PM every day. And the phone is always warm to the touch.
The only thing I can think of that changed was I noticed that my Google Contacts were not syncing properly and so I tried a bunch of stuff to get them syncing properly. I went through a checklist of stuff like wiping the contact apps data, deleting the google account and recreating, etc. I might have deleted and then installed the contact app, I'm not sure. I just tried a bunch of stuff until the contacts were syncing correctly. I don't think that is the cause - I mention it because it is the only change I can think of around the time the battery life degraded. I don't allow the play store to auto update apps, so other than something related to google contacts, there were no app version changes. I didn't change anything about how I use the phone.
I am running the ROM from here:
http://forum.xda-developers.com/nexus-6/development/rom-5-1lightromstock-lmy47e-03-19-2015-t3059493
which is, I believe, very close to stock. Since the May security patch level came out shortly after I started having battery life problems, I did a clean install of that version. I wiped system, cache, dalvik and data in TWRP before installing the new version. I've run that for a few days now and my battery life is still terrible and the phone is always warm.
Anyone have any ideas what could be causing the problem or how I can diagnose the problem? I've looked at the battery stats, but because I've never looked at them before, I have no idea what they are supposed to look like. The top item in the list is always "Android System" at 18 - 30% of the battery use.

is google play services eating a lot of the battery?

Or did you tried betterbatterystats? Or smth like that? So you can track in detail.

your phone is constantly awake, not sleeping. AND you have both Bluetooth and WiFi turned on. you'll get terrible battery. one way to rectify it, kinda, is to turn your screen brightness down a lot. since your phone is constantly awake, that means your CPU is working doing something, is it by your choice?

I want bluetooth and wifi always on and I have never had to turn them off to conserve battery before.
It sounds like the problem is the phone is awake all the time. Now how do I find out why?

you can use something like wakelock detector(app) to find if you have any unusual wakelocks.

I agree, it is abnormal for the phone to be awake the whole time from 9am-2pm including long periods when screen was off. The at 2pm (slgithly after you started charging), those wakelocks stopped and remained stopped even after you want back off the charger. It might be a clue... any idea what might have changed just after 2pm (some program that you stopped or killed or setting that you changed)? At any rate I agree something like better battery stats is a valuable tool to help narrow down the cause of wakelocks although it's not always easy.
Another thing I notice is that your phone signal is very weak... red orange and yellow. (mine is mostly green with a little yellow). They put that on the battery screen because it certainly can affect battery life as you phone has to work harder just to find/keep its signal. Weak signal might possibly be related to the wakelocks although I'm not sure. Most likely phone signal is something you can't control or wouldn't change, unless you were in a different location or unless (longshot) it is related to your radio. You might try flashing stock radio if you have a different radio.

Thanks for your help. I can't remember if I did anything that could have changed the behavior around 2PM, but now that I know, I can keep an eye out for any similar change.
I have never looked at the battery stats before, so I don't know if that cell signal is how it has always been or something that has changed recently. I suspect it has always been like that because I usually see 0 or 1 bars on the status bar icon when I am at home. I have not changed radios, but I may try that after figuring out this problem.
It looks like I need to look at wavelocks to try to see what is keeping the phone awake. I'll investigate and report back with results and or further questions.

Just remembering you said it started after the May security patch.
I'm assuming you flashed it rather than OTA'd it.
Here is the recent history of factory images for Nexus 6
FEB: MMB29Q
MAR: MMB29V
APR: MMB29X, MOB30D
MAY: MMB30G, MOB30I
The MOB series introduced a new radio (the same new radio in MOB30D and MOB30I). I heard that the reason there are two imagesw in April and May is that not all carriers have tested/approved the new radio yet (those carriers - whoever they are - delivered OTA's to MMB29X and to MMB20G). I haven't heard any reports of problems from the new radio and I know it works fine for me on AT&T. Maybe if you came from something other than MOB30D before, and just changed to MOB30I in May, then it might be worth trying the radio from MMB30G instead (there shouldn't be any problem mixing/matching radios.. radio is independent of the rest of the image).
---------- Post added at 01:07 PM ---------- Previous post was at 12:47 PM ----------
I just read you didn't change radio and you've always had a low signal. So, disregard my post above.
another thing - a standard troubleshooting suggestion (not related to anything in your post), try wiping cache in recovery.

It didn't start after the May security patch. It started a bit before and it started out of the blue. I did a clean install of the updated ROM with the may security patch. I was thinking the clean install of the ROM would fix it, but there was no change. One thing I didn't mention is that after installing the ROM, I restored system data and user apps and data with Titanium backup.

Thank you all for your help. I looked at the google backup settings and I had backup turned on, but there was no backup account set. I put in my google account as the backup account. So far the problem is gone. That doesn't prove the missing account was the cause, so if the problem comes back, I think that disabling backup entirely should "fix" it.

Tremendous battery drain on WIFI

Hey guys, I am running stock 4.0.3 rooted with supersu and using the latest franco kernel. I am getting massive drains even while using the phone on wifi and keeping it on standby, while connected to wifi. Getting drains about 3.3-4% per hour on standby on wifi. This is absolutely crazy. I tried some older suggestions mentioned here https://forum.xda-developers.com/showpost.php?p=62074306&postcount=118 . But even that doesn't work. Battery drain is normal on mobile data, but when connected to wifi it absolutely goes crazy. Can anyone provide any insight? There are no rogue apps, I have been checking through better battery , wld , accu battery, etc.

You've probably already turned it off, but I'll just point it out in the rare instance, but make sure scanning is off. However, I did notice that you said it is when wifi is on and your phone is sleeping when you get that drain. A fix is to go into wifi settings and under "Keep Wi-fi on during sleep", pick the only plugged in option. Ideally, you should get to the bottom of this issue, but if you don't have the time and no one else figures it out, this may help.
EDIT: I wonder if smart wifi switcher has anything to do with it? Wifi connectivity fluctuates and if you have two connections that have very similar signal strength, would your phone constantly switch between the two networks in a futile manner? If this does happen, I can see that draining your battery significantly, but this is based on the premise that the switcher does not have some type of buffer zone where it does not switch if the difference is negligible.

Yep, I always keep scanning off! And i did try with that suggestion too, I changed the setting to never and it still drained battery. Wifi stayed on for sometime even though i set it to never and then finally turns off after a period of time, but i think that could potentially drain more battery? Are you using wifi all the time? What are your stats?
I have all those settings turned off, smart switcher, ipv6, scanning, etc

Last thing I can think of is trying to use stock kernel to see if it is FK that is the culprit. FK shouldn't be the issue, but perhaps something screwed up during the flashing process? Now I'm essentially just asking you to do trial and error

Nah man, I trust FK more than stock
I have had similar issues with stock as well.
What are your battery statistics?

Note that I'm in Beta 3 and running its stock kernel so I don't really see the usefulness of giving my battery stats, but yes, battery life for me has been good and unaffected by wifi draining.

Whoa, how the hell do you even get 2 hours 17 mins sot with 85% still remaining?
Is it really just me suffering from this wifi drain bug?

It's most likely not just you, but based on my perusal of the 3T forums (especially on the FK thread because that's most relevant to how you set up your phone), not many people are facing this issue. Does betterbattery stats not show anything funky or out of the ordinary? Can you post a screenshot of your betterybattery stats including the kernel wakelocks, alarms, and partial wakelocks page?

Check these out. I am totally fed up. I think I might have a faulty unit.
Getting 4% drain on standby!

I'm beginning to think it's not wifi, but the app Saavn. It may act differently when on wifi vs on cellular data and remain active constantly when on wifi. I google searched the app and its potential of being poorly optimized app, and there are reports of it never turning off and running in the background. If that is the case, it should be showing up on BBS as more of a drain, but for some reason it isn't. Still, try uninstalling the app and see what happens.
In the end, if this doesn't solve the issue, I'm beginning to think a factory reset maybe in order. I wish you also gave me BBS alarm wakeups page because that would help see if Saavn is constantly firing off alarms or not.

Go to your "Location settings" and into the 3 dot menu in upper right. Turn everything off.

do you have wifi calling on? turn it off and see

I don't have any option to turn off wifi calling in there. I am running the beta 7.1.1 now though. But the problem still persists. Too much drain when using wifi, it's being shown as android system drain. I've seen many people reporting it, so it's not just me. But for the life of me, I can't figure out what's causing it!

Issue resolved with latest 4.1.0 and some usage pattern changes. Mod, please close the thread. Thank you!
