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?

Switch to CM7.2 stable?

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.
Hi Guys. Im on Lineage OS and i my phone cant go to deep sleep. In BBS i have this weird wakelock. Someone know how to find whats going on?
Ok, after few reboots wakelock is gone, if someone know what was that i would to know too
I am getting the powermanager wakelocks, same as shown in the photo, is that a concern ?
Hi all. I noticed that the phone does not go into deep sleep mode sometimes. I put my phone and galaxy watch 4 into airplane mode through the night but the phone never goes into a deep sleep because of kernel wakelocks (npu_run_wlock) and google play services. After restarting the device, the situation returns to normal and the phone goes into a deep sleep. Do you know what could be the reason for this?
could reproduce and report to samsung (don't reboot tho, it'll delete the issue log) use samsung members app > get help > error report
