[Q] How to determine what is keeping Android from deep sleep - Android Q&A, Help & Troubleshooting

I have an HTC Rezound running Android 4.0.1, and I notice that it very rarely enters sleep mode, even after the screen has been off for a very long period of time.
Is there any way I can determine which apps are keeping the phone from entering sleep mode? ..or which app is waking it up constantly, whichever the case may actually be?
I have tried doing a logcat and just let it run for a while after turning the screen off, but I'm not quite sure what to look for in the results..
any help?

BUMP
Nobody knows?

look for the app Betterbatterystats, there are also tutorials on how to set it up here on XDA, i can't really tell you how to use it bec. Im not familiar with the app, i have it but rarely use it.

Android for Sleep problems?

I use the sleep app to help me track my sleeping patterns and so forth (great app btw). However, ever since I got my LTE I am noticing that the phone is not charging when I put the phone is "sleep mode" within the Sleep app. Anyone know of any fixes?
I used to use this on my OG EVO also bit have yet to try it on my LTE...I'll download it and see if I get the same issue.
Thanks. I'm interested in the results.

I didn't seem.to have any issues. I woke up to a 100% charged phone. I didn't change any settings. Just set an alarm and.went to sleep. Maybe you can try to uninstall and leave all setting stock ,if you changed any to begin with, and test your results. Then tweak it a little at a time to see if you can track down what setting is giving you problems. Only.thing I can think of.

[Q] ICS and Sleep as Android - Screen On problem

Hi!
There is a very good app in google play to track sleep, it is called Sleep as Android.
It uses accelerometers to try to estimate how deep is your sleep.
However, since ICS was released, this app cannot get accelerometers data if the phone is in stand by and screen is off.
So, the screen stays on all the time, but with a 100% black image.
My question is: can it harm the RAZR screen?
Thanks,
Ronan
I don't know, i have the same problem
I hope you will soon find
did anything ever come of this? I just downloaded it last night and noticed this.

[Q] Screen dims, but won't turn off (intermittent)

Hi, I'm running CM7.2 nightlies on an LG P999 (Canadian version of the G2x). Over the past few weeks, I've had issues where the screen will dim as it approaches the display timeout, but never turn off completely. This is intermittent, and I have yet to notice a consistent pattern. I've been searching to try to find a cause but with no luck so far. I am familiar with using BetterBatteryStats and thelike to track down issues with wakelocks and not going to sleep, but i don't know what to use/look for in this instance (ie how to identify apps that might block the screen from shutting down). Any suggestions?

I would recommend using a logcat app to try and narrow down your problems, the recently featured | AIOlog - All in One Android Logger v0.3 is an excellent tool for this job, and if you would prefer to use an app for your phone try CatLog - Logcat Reader. Now as far as what to look for look for things in the logcat that refer to package's (I.E com.android.phone) and wake-locks or changes in power states. For example if you see that a package when in use is causing a wake-lock or keeps changing the power state (It may for example be preventing the display from completely shutting off because it thinks your still using the app and thus should keep the screen on), you know that may be the culprit. If you can narrow down a list of suspected apps carefully disable or uninstall them one at a time (Be very careful if it's a system app, make a backup first), and see if this fixes your problem. Let me know if you need any help troubleshooting !

[Q] Phone is not able to get in Deep Sleep mode. How can I fix that?

I use CPUspy to see what's going on at processor. I can't see deep sleep and my battery dies in a very short time period.
I have stock ics 4.0.4 XXLQ6 and I didn't root my device. As I asked, how can I fix this problem?
Thanks.
Turn off auto-sync on every app; if you want to check mail/FB/Twitter/whatever, do it manually. Turn off data when you're not using it. Tho WiFi uses a lot less juice than data, turn that off too when you're not using it.
Unless you root your phone, that's about it. There are probably apps you can freeze that might help things, but you won't be able to do that unless you root.
Read the BBS thread, lots of ideas there. You may as well install BBS, the logs should give you an idea of exactly what's causing wakelocks which are killing your battery. If it's mostly stuff syncing, then you might be able to get a handle on it. If it's stuff that needs freezing, again, you won't be able to do that unless you root your phone.

I´ve tried everything, my S4 won’t go to DEEP SLEEP

**my mistake, can someone move this to the AT&T forum?**
Hi there, I have this problem; my AT&T GS4 does not use the deep sleep state. I have made some research, and from what I understood, this problem has to be a result of any program that keeps triggering the phone to get awake.
So, I have the phone unlocked, rooted and ALL the sensors off, expect from gsm signal. With titanium back I have uninstalled the programs that I´ll never gonna use (mostly AT&T bloadware) and frozen the ones that I don’t want to use right know, but maybe by deleting them I would get into a problem (like S-Voice) or just because some day I would like to give them a try. Finally, there are the programs that I would like to keep, but I don’t want to let them make any cpu use while I am not using them. I used an application called Greenyfi, a good example of why this program is the best for the last propose, is the use of programs like google maps, in where I do want to use it, but, just when I open the app. Also, I used the app “Autostarts” to prevent applications to start after some events (like startup, state change, etc..)
With all that been said, I am steel not getting deep sleep, in any situation. I´am not saying that my battery life is bad, I think I can get easily 4-5 screen time use. But, by not getting into deep sleep, the phone is allways using the cpu at 384mhz, so the battery goes down in a range of 1.5 to 2 % per hour (10 hours of no use and 20% less battery).
SO, for you to see the problem better. I did a little experiment. Restart the phone, put it into flight mode and let it “sleep” for the night, the results are attached.
PD: Whatsapp isn’t the problem; I can froze it and still 0% deep sleep.
did you ever solve this.. my t mobile s4 is not going into deep sleep staying at 384mhz
Had this problem a while ago. Ran Greenify and froze things with TiBu but the phone didn't go into deep sleep. I ended up flashing back to stock then re rooted. Problem solved.
same here. reset didn't work.. flashing back to stock didn't work, flashing stock and then a reset worked.. and reinstalled everything and still going into deep sleep now.. now sure what it was, but something in system was ffd up.
