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?

Sometimes I find NC cannot get into deep sleep mode after screen is off.
Once it happens, I have to try to toggle the WIFI and auto screen rotation, kill all the Apps in memory and then check if it could get into deep sleep mode again. That is really annoying and makes NC unfriendly to battery life .
Is there any method to make sure NC will get into deep sleep mode when screen is off? It will be highly appreciated~
"Better Battery Stats" can tell you what is causing wakelocks.

I never fixed my SOD problem on my TF101. I'm running AOKP Milestone 6 and Guevor's Kernel-ICS-V23-OC1700-fb-AOKP_690
I initially just used that Wakelock app to prevent it from going into deep sleep, but I was highly dissatisfied with the battery life.
What I started doing now is using this app: https://play.google.com/store/apps/details?id=com.easy.battery.saver&hl=en
I found that my TF101 does fine when it goes into deep sleep, but not if it's deep sleep for too long of a time period. With the battery saver app, I have it customized so that when the screen is off, the wifi will turn off as well. The trick is also setting it up so that the wifi will enable wifi again every fifteen minutes for thirty seconds. That brings the TF101 out of deep sleep for a little bit, lets it sync gmail/FB/etc., and then go back to deep sleep.
The benefit of this is that it prevents SOD while still maintaining decent battery life by allowing your TF101 to at least go into deep sleep once in a while instead of keeping it awake 24/7. I tried playing around with 30 minute intervals for the wifi turning on/off but I had a SOD. 15 minutes seems to be working!
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

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!
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.
