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?

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.

[Q] Is my battery broken?

Hey I have just bought HTC One 2 days ago. Compared to my old Sensation XE battery life completly sucks. I usually use phone without battery saver, on auto brightness and with Wi-Fi/3g turned on only on demand. Today 8 hours after unplugging phone from the charger I only have 26%. Screen was turned on for 2 hours and 45 minutes only and Wi-Fi worked for 3 hours and 46 mins. I might also say that I did not charge my One before usage to 100% as HTC advised. Was that very crucial? Do you think that phone might be broken or I should just give him time to settle baterry better.

That's sounds like what I get. I turn off mobile data when using WiFi and vice versa. I always use power saver unless I'm 3D gaming. Which is only on the weekends.
I've had mine for 3 months now.
I've seen people get 7:00 screen time on stock unrooted.
I think my battery's broken too. I can barely reach 3 hours of screen time. With 2 hours I get like 11 maybe 12 hours of on time. Something's wrong with our phones...
Does anyone have any suggestions?

Does anyone see a problem with my battery I have been on wifi the whole time with brightness at 20%.I never had this bad of a drain before and all I did was look at facebook for maybe 5 minutes.I also closed the app after I was done using it.

Your battery stats seem on par with me and the OP. Seems that only a select few phones get decent battery life.

My kernel (android os) has been in the 25-35% range,it has never been that high before.

battery life lousy
I get pretty horrible drain too. I charged it to nearly full around 7:30 last night. I took about 2 minutes of video, sent one text, and checked my email 3 times. After that I went to sleep and the phone sat idle. At 6:30 this morning, I'm down to 9%.

Wow, that's real bad.. When my phone is off during night maybe 7% is gone. Then again I'm rooted and use greenify aswell as battery doctor if that has any affect.
On screen time seems like my battery drains pretty fast too though. After 2 hours of music and surfing and watching videos I guess atleast 40% would be gone.

My battery life became horrible, too. My phones loses 4% per unused hour. No App seems to be responsible for that drain. Flightmode or powersaving mode ain't making a difference. I hope we'll find a solution for our drain.

@Racingmatt your power management services is on for quite a bit. do you have alarms.? i would bet that you either that maps location enabled or something of the sort. cause you also have NLPcollector on for around 40 minutes which is a bit much. also i would turn off GPS if your not actively using it.
@Rachorid how are you setting up your wifi? is it set to always be on? or set to turn off when screen off? you have alot of wifi wake. might be due to that. i know when i'm at home my wifi actively pings all devices connected which will force wake up my phone. yea its a bit annoying but i live with it. otherwise i just keep my phone plugged in.
if you both can get some SS of alarms i can give you a better idea. and when you SS the alarms make sure to click on the ones with the most wake lock so i can see the secondary screen that shows what the actual wakelock command is happening.

Here are the latest stats. As you can see many Google wakes.. removing Maps/Now/GMail/turning of Location (a few days ago) had no impact on my drain. The 2nd app on Partial Wakelocks was used actively.
I also disabled Wifi for about 2 hours.. no impact, too. Flightmode also had no impact (a few days ago).

The reason I didnt give you a alarm ss is because I didn't have any alarms when I went to the alarms section. I also had all locations services including GPS enabled but I just now disabled GPS but left network location enabled I'll give you a screenshot later so you can see the differences

I know exactly how you feel that's what happened to me,u was expecting so much from the battery and it turned out to be the worst..give ya some advice...3g drains the **** out of the battery ,so always jeep it off and turn it on only when you wanna use it...that way the battery will be acceptable... Also flashing a custom Rom would help...o recommend arhd

I had awesome battery life a month ago with Wifi always on, auto. brightness and every app on hourly sync. (I have my phone since 7th of march) Sometimes I didn't lost a percent over night (8 hours) and I just don't know what it could be because I didn't install another app and no app seems to be responsible for that stanby drain. My on-screen battery life is still good. It also doesn't matter which ROM or kernel I'm using.

Here is my latest stats after 12 hours with 5 minutes of GPS use (turned off when not using)and network location on all the time with 3g/4g on all the time(turns off after a period of inactivity) . I can't give you a alarm stat because I'm not rooted.

Lithium-Ion batteries used in today's smartphones need atleast 10 cycles to show optimum power
so hold on until 2 weeks then you will get the full performance
i get 2 days of battery on my HTC One (since i dont have internet on my Simcard)
its 2G connection and auto Brightness and switched bloatwares off
i use Android Revolution HD 12.2

with normal use 3.6%/h is pretty reasonable. how much screen on time was that including?

Daydream on Charging can cause wakelocks

I have realised (at least for me) that using Daydream whilst AC Charging is causing a wakelock on the phone after you remove from charge (no deep sleep at all aka 100% awake time).
My phone is pure stock at the moment, no root or any modifications.
I am not sure on the exact triggers, my wakelock seemed to activate when my alarm goes off in the morning causing my screen to turn to daydream mode, I then pick the phone up on the second alarm and unplug before turning the screen off, then the phone fails to enter deep sleep until you reboot.
Others appear to be having the same issues.
For now I have disabled Daydream on charging and I hope this stops the wakelock issue, but as to why it is happening at all I am not sure, the lack of battery stats on KitKat at the moment is fairly irritating.
Anyone else having 100% awake issues? and if so do you use daydream or alarms whilst charging? If so please let us know, and try to disable daydream whilst charging to see if that helps.
(FYI I am using CPU Spy to determine the exact time spent in "deep sleep", but you can get a general idea of how much awake time you have in the general android battery section of settings.)

Thank you for your post. I hav those issues too and was just starting to look into it. I too am using daydream on charge and seen a wakelock yesterday, that i could get rid off by rebooting. I then recharged to get through the rest of the day and the lock came back. And this morning: exact same thing again. I disabled Daydream alltogether and see if it really is the culprit on my system.
Edit: i don't use alarms on that phone at all.

This morning I had finished my first full charge since disabling daydream and my wake-lock issues appear to have gone (hopefully for good!).

First Full Charge after disabling Daydreams: 3h of the charger and AndroidOS kept my phone awake for 1,5h. So it seems that it was not daydream on my device

Just the same as wireless charging causing random wakelocks after you take it off charge, never got fixed on the N4 and the problem seems to have carried on with the N5. Problem is you sometimes don't realise until you have little or no battery left!

no not yet, they don't like 4.4 /nexus 5 do they. I just know something was up as I put it on the wireless charging pad over night and by lunch time I was at 60% with little usage. I recharged and rebooted and then it was back to normal. Seen it all before with the N4.

I leave mine connected to WiFi, it uses way less battery than LTE/4G
Also disabled BT and WiFi location scanning in Location Access > Advanced Settings
Disable any apps you don't use that may be running in the background
And weirdly, my battery life improved best when I set the phone battery settings to "Performance mode" which goes against everything it's meant to do, but that's what happened, worth a try with yours for 24/48 hours to test

I had S10 plus and I went to sleep it was 99% when I woke up it was around 64% sold it 2 day ago and got the P30 pro , today is my 4th day with it and when I wake up it’s always above 90% leaving bluetooth WiFi all running normal so don’t know what’s happening with you....

Went to bed at 100%, woke up and it was at 99% this morning (11 hours on battery)

Try to find the cause in Settings - Battery - Usage and detail of batteryusage. This can sometimes indentify an app causing this.
Sometimes problems are solved by wiping the chache partition. Youtube movie how to wipe cache

Do you have aod (always in disolay) on during the night?
That will drain a few percent also. I personaloy turn off aod between 11pm and 7am.

I was getting quite a bit of drain when I had AOD enabled, so I disabled it and chose to use Double tap to wake instead, however I also debloated through ADB around the same time so could have been a rogue package that I removed..

Double tap to wake will use power keeping the screen's digitizer panel active waiting for your taps
I always disable everything to do with keeping any part of the phone awake during sleep, AOD, gestures, taps etc, and with DND enabled until 9am that will kill any notifications waking it up too
Looking at the battery usage overnight, the phone logs only 3-4 very short wake events, one I know is it checking for firmware updates and could be disabled, others will likely be whatsapp/outlook

Although this is true, it's extremely minimal in my opinion, I go to sleep with my phone on 100% & consistently wake up on 99-98% also I don't have DND on at night so the odd text message or email may come through and wake up the screen

Good to know, yea I managed to get mine down to 1% drain overnight too, as good as their battery management is for that side of things, it has ruined WhatsApp, no matter what I set to exclude it from power saving options I still only get messages when I wake the phone up myself, sometimes only when I actually open WhatsApp, it's gotten so bad now my gf texts me to tell me she's sent me something on WhatsApp, she can even text me while I am using the phone to tell me that and I still never received anything until I open whatsapp
Seems this problem goes back many years with many previous Huawei devices unfortunately which means there is likely never going to be a fix

I removed a lot of Huawei's preinstalled apps to as I don't really use them, I also had the exact same issue with WhatsApp & Twitter, the way I "solved it" strangely enough was disabling them from settings > battery > app launch & restarting my device, then re-enabling them & restarting again, it's been fine ever since could have just been a fluke but it worked so..

Yea I've changed that App Launch setting many times without any luck, I found a post from way back in 2012 I think it was saying there were 3 different settings that needed changing to fix the exact same problem that still happens today, needless to say this will be my last Huawei phone, not difficult to whitelist something as widely used as WhatsApp, I mean normal messages works fine and that's a Google app not a Huawei app so no reason another 3rd party app couldn't do the same if they wanted it to

Do you have aod (always in disolay) on during the night?
That will drain a few percent also. I personaloy turn off aod between 11pm and 7am.

As I mentioned above I have double tap to wake enabled and lose 1-2% so it can't be that...

Question S21 Ultra Always On Display

Hi everyone.
Just wanted the community's opinion on what your thoughts are about the AOD.
How many of you use it regularly? And those that do, what is your preferred setting - Always on (+/- scheduled) or Tap to Show for 10 seconds? What has been your experience with battery life and overall usability? Any tips or tricks? Any downsides?
Those who don't use AOD, could you please post your reasons, along with any experience with battery drain or screen burn in or other issues.
I'd like to use AOD (on the always on setting), but am not very sure what it costs in term of battery or screen life. The former is a non-issue for me personally but if it's going to affect screen life or quality, I may hesitate a little. I tried the tap to wake for 10 seconds thing but it seems to beat the purpose as I can just as easily go to the lockscreen with a double tap and neccessitating user-interaction negates any real benefit of an always-on feature.
My current settings are:
AOD Always on (scheduled from 7am to 10pm)
FIngerprint reader always on (so I can go directly from AOD to Homescreen without having to go through the lockscreen)
Fingerprint icon set to tap-to-show (just as a hint if i ever miss hitting the correct position when trying to unlock)
Your thoughts and suggestions are most welcome.

I only use AOD via AODNotify...that should have been an option in the poll.

I use a Tasker profile to turn AOD on (always) when a message arrives and revert back to tap to show when message is cleared.

I keep it on all the time, really helpful and doesn't seem to drain too much battery.
Btw does anyone know if it's possible to add weather info to the S21Us AOD?
One of the few things I still miss from my P4XL..

I don't use it drains a lot of battery

I use to always have it active on my 10+ but it got to be annoying. Tap on is fine.
I don't care to be informed every bloody second... that ain't no way to live.

Wasn't even aware something like that existed. Thanks for the heads-up, will check it out.
Poll updated with new option.

I like to keep the setting to always on with fingerprint always enabled showing thumbprint on screen always .
What i have noticed is the aod doesnt turn off when the phone is in pocket or lying upside down.
That would save so much battery.
AOD used to turn off automatically in my s9plus when the phone was in pocket .
May be this feature is disabled due to lack of active proximity sensor

The 10+ has a proximity sensor and AOD always remains on if set to. The face down off be nice.
Maybe it caused issues in the past. Samsung is sort of hit or miss though.
I have yet to use the fingerprint sensor, lol don't even know if it works.
Last thing I want is to get locked out of a device.
As soon as you set an access password this can happen and through no fault of your own. A hardware failure or glitch can trigger it. Had no password been set the setting wouldn't be enforced. I've gotten locked out of a PC bios like that, never again.

Does the fingerprint icon shift around like the clock or battery percentage (it has very little room to move around though)?
I hope it does, otherwise it'll land up causing screen burn if it's in the same position with the same pattern all the time. Have you noticed this?

Probably shifts it over a few pixels but in bright light over time it will cause uneven aging.

I set that sucker to always on all the time and at max brightness to boot. Cannot use a phone without the option.

According to your battery stats, how much drain is attributed to the AOD? Could you post a screenshot at the end of a day please?

I don't know how much drain is attributed to the AOD. As soon as I get the newest Samsung I turn it in and crank it up before I literally do anything else. I keep every setting on ALL the time (Bluetooth, wifi, nfc, etc). The battery gets me through a regular day. I'll try and post a screen shot. Today I took it off the charger 3 hours ago and I haven't stopped using the phone. I'm sitting at 85%.

You monster, you.
My smartwatch (Fit2, cheap) negates the need for AOD.

I have a serious addiction to smart phones, lol. I'm on mine about 12 hours a day. Mostly playing games or surfing the net. Today off my charger for 2.5 hours and I'm at 88% lol.

Cycle the battery between 35-65% if you can (and then raise both those numbers slowly over time) or else you will fry your battery fast.
If you're just going to buy a new phone in 2 years, then, don't bother with what I said.
