P7000 has a reasonable battery but it just refuses to go to deep sleep with cpu working non-stop and wakelock actives 24/7. Has anyone successfully make it goes into deep sleep to conserve and save battery?
Please share your findings. Thanks.

My tf not going to deep sleep, i'm on 3.1 primordial.
Someone have the same issue?

Yes. Mine is too. and i haven't figured out why.
Mine seems to stay awake (according to the battery graph) if it's plugged in to the dock.
What do you mean by deep sleep, there's only 1 sleep mode and that's when the screen simply dims off yes?
If you install cpuspy, deep sleep is one of the cpu frequencies (i guess) that is lower than 216 mhz. Mine seems to be stuck at 216 instead of deep sleep whem i turn off the screen.

+1 for not entering Deep Sleep. I'm running 3.2.1 ... and I did notice that my TF did enter Deep Sleep some time; but just turning off the display doesn't enter deep sleep.
Did anyone figure out why Deep Sleep is not being entered, or what does it take to enter Deep Sleep?
Hello everyone! I was just wondering if one of the developers can look at here. It's about a frequency in the kernels that may improve our battery life. Untill now all the kernels are working really good, but i was wondering if one of the developers can make this frequency called "Deep Sleep" working when we don't use our phone much. If someone can make this freq working more than the others when we don't use the phone i think we are going to have a perfect battery life! Thanks!

This is the thread of the x10 kernel. There you can see that the deep sleep is using more than the minimum frequency. I think that this frequency is using some low voltage or something like that!
Looks great this kernel to X10,the devs make lots of things on it,look how many CPU governors they have!And these deep sleep seen great too!
Hope our devs will take a look and see what features they can bring to our X8!
I hope that someone will see this because i think that those things can work on our device
We have Deep Sleep on X8. Install CPU Spy from Market and you will see. Here is screenshot from my phone:
+1 i hawe spy cpu and deep sleep is to.
bad in this kernel deep sleep hawe changed voltage on sleep freguenz and hi has many improwments
Yes that is what i am talking about ... we have deep sleep but the frequency is not changed (i think). That's why i posted this so the devs can take a look at it
Do you know what is Deep Sleep (sleep mode)? There is no frequency. It is like sleep mode on computer or laptop. I have found this about it in Google:
Q: My question is what exactly does "sleep mode" do on android systems?
A: Primarily, it shuts down the CPU. Along the way, non-essential radios (WiFi, GPS) will have been shut down as well.
Q: What does it stop, what doesn't it stop, etc.
A: About the only thing you can count on not stopping is the GSM or CDMA radio (for incoming calls, SMSes, and IP packets) and AlarmManager.
Q: By sleep mode I mean, of course, when you press the power button and the screen goes black.
A: Actually, that's not sleep mode, per se. That is the screen turning off.
The device will go into sleep mode shortly thereafter, if nothing is keeping it awake with a WakeLock. However, there is no guarantee that within a millisecond of you pressing that button and the screen turning off that the CPU is off.

If we don't have Deep Sleep battery will be drained very fast
I am on the latest Slim Bean with Franco R31 and no matter what governor/min/max I set it does not go into deep sleep. How can I find out which program is causing this?

Install and set up the app, charge your phone, unplug it and don't use it for 4-5 hrs (overnight is even better), check the results. If you can't identify what's keeping your phone awake pull a log with the app, post it in the thread and ask for help.
My (stock) Nexus 4 never goes in to deep sleep despite the Android battery thingy showing nothing (or very little) awake time. My Xperia S was always awake according to the same thing but entered deep sleep readily

I had this problem. I found that it was a live wallpaper that was keeping the phone from going into deep sleep. As soon as I switched to a standard wallpaper I was able to get 70% deep sleep whilst previously it never went into deep sleep.
Hope this helps

Another recommended app Wakelock Detector at Google Play
Hi Guys,
I am wondering is there any of you having same issue as me ?
I am using TILAPIA device and suffering from around 5% / H battery drain during idle (all off and in airplane mode)
strangely, BBS report is showing my device is in sleep mode for more than 90% of the time
as per now what I can think of is to set tasker profile to shut down the device when screen is off for 5 mins
but I am still curious why and what is the cause of battery drain while the device is actually in "sleep mode"
Thank you

Hi, I have same problem. Asking if anyone can see something weird in BBS dump in post here
P.S. Concluded that my case is totally same as described here
Yesterday I bought a S6000L tablet and I like it so far.
After having it standby for one night I have the following questions/observations:
•During standby (8 hours, WiFi off) the S6000 MT8389 will not enter deep sleep and stays on 1200mHz, is this normal behaviour? (checked with CPU Spy).
•Found a similar experience with the deep sleep here on XDA (other Lenovo model, same chipset): http://forum.xda-developers.com/lenovo-a3000/development/rom-lenovo-ideatab-a3000-h-call-t2441135/page23 . This was eventually "cured" by a custom rom/kernel, so it seems that deep sleep is possible.
•I checked network connectivity (by pinging the S6000) and WiFi is disconnecting as it should when screen off (have this set under advanced WiFi settings). WiFi always on could be a source for no deep sleep.
•The battery usage was about 4% in 8 hours so 0,5% per hour seems reasonable. I just don't understand how this is possible with no deep sleep.
Maybe I'm to anal by this deep sleep according to the 0,5% drainage per hour but I'm thinking it could be better .
ps We need an own Idea forum!
