So after using about 3 GB kernels (Nubecoder, mkasick, IAP) for the past few days, I've noticed that my CPU Spy app has not detected any deep sleep frequencies whatsoever. Is this normal? Because from what I can remember, past Froyo kernels I've run have always used deep sleep frequencies when left idle.

From what I've read, we don't literally use deep sleep, but I believe it can be done by a kernel dev taking source from a modified nexus kernel. To my knowledge, our epics aren't really ever entering deep sleep (unless you count shutting off your phone as deep sleep, lol) just a hibernation-ish sleep? Like a pre-quel to deep sleep, but no 'true' deep sleep with the kernels we have at the moment. I sure do wish a kernel dev looked into it though. The battery savings would be insane that it even makes ME want to cook the code into the kernel if I had the proper experience.

No that is not normal. If you have the phone off charge, screen off and not using it for about 15 minutes, some deep sleep should be seen in CPUSpy. It does not sleep while on charge. If you cannot obtain deep sleep according to CPUSpy you should Odin back to stock and move forward from there or get better battery stats and try to find out what is keeping your phone awake. Perhaps a bad sync or chat app like gtalk, google + or something like that.

My battery is draining like CRAZY and i cant seem to find out what the issue is. Ive tried calibration several times and using a task manager that turns off running apps every few seconds(which seemed to make it worse) and that didn't help. Auto updates are turned off and fbook is only set to update every hour and brightness is set to minimum yet my battery only seem to last 8hrs. please help. i would really like to pinpoint what the issue is.
Oh...im running ERA Legendary 2.1, CPU speed and voltages are stock
That screenshot is worthless. It doesn't show anything useful. Percentages are meaningless. Get Betterbatterystats to see what is running as far as processes and partial wakes. Get CPUspy. To make sure your phone is going into deep sleep. Get Memory Booster Lite to see what is using your battery and get rid of the auto task killer. That will kill your battery fast.

i only posted the screen shot to show the time vs percentage. i already got rid of the task killer and here is a screenshot from better battery stats. idk how to stop the processes though...
Again the percentages mean nothing. In Gingerbread everything goes through Android system so it will always be highest. If you use your phone only an hour or two a day then it will drop to around 60% with cell standby getting higher. They will always add up to 100% whether on a minute or 10 hours.
You didn't post the partial wake locks screen. Also did you check CPUspy for deep sleep? Did you uninstall the autokiller? You can go into settings>applications>running services and stop applications that shouldn't be running like Facebook or music and video players, etc. Sometimes it's best to get an app like Bloat freezer and freeze apps that keep reloading if you don't use them often.

Another question and maybe the most important...what is your screen on time? I didn't see it in the screen shots. I think Max screen on Time I have gotten is right around 4hours. All the battery tweaks in the world wont help, if your screen is on a lot. Also...make sure to freeze drm, sns and system updates. Use randomlking's zip file.
If none of that works...wash, rinse, repeat. Wipe clean and reflash, rom and kernel.

As I'm sure you know, everyone's battery drainage is widely independent. However; I'm on "stock" Legendary 2.1 and recently with the updated Samurai kernel as well and run Juice Defender Ultimate. I've got some advance settings set but over the past 3-4 days, I average about 20 to 22 hours on a single charge.
My usage in an average day is: about 20-30 texts, about 10 minutes of phone calls, 10-12 emails in and out, 10 minutes of web, whatever app updates there may be and maybe about 15-30 minutes of light to medium use games.
If JDU is something you might want to look into, I would be more than willing to post my setup to get you started. <--For some reason, people are real stingy with their JDU settings.
This kinda thing just happens sometimes, and usually clears up on it's own. Especially common after flashing new software.

I've been going back and forth and trying to figure out what the issue is, but I'm wondering if anyone else is having Deep Sleep issues when using CM9 on the GSM Galaxy Nexus? I can restore my Nandroid of stock 4.0.4 with the UGLC1 modem and according to CPU Spy I have no problem going into Deep Sleep and having a high deep sleep percentage. I'm using the 20120518 CM9 nightly and I just can't seem to manage deep sleep. I went into CWM formatted /system, /data, and /cache. I then ran the jBroid kernel cleaning script and installed CM9. Did a factory data wipe and then booted it up. I didn't install gapps and used ADB to install CPU spy. So no google account or anything. I turned on WiFi, reset the timers in CPU Spy and left the phone alone for at least an hour. After an hour I had a sleep time of 3%. Any thoughts or solutions?
Is it staying fully connected. It might be disconnecting and reconnecting not allowing the phone to sleep.

Is there a way I can check this? This could be possible, but it seems like it should be causing stock 4.0.4 to never deep sleep and not just CM9. I might have to try CM9 with some different kernels and see.

It could be a bad flash. Redownload it and reflash wiping clean... data dalvik and formatting the /system. Then see what happens. If that doesn't work try the samurai kernel .

deep sleep cpu spy
I was having the same issue with CM9. I was showing 45% 350mhz 45% deep sleep on CM9 but when on stock I was deep sleep 80%+. I reset the cpu spy timers and now after 18 hours cpu spy time I'm back at 80% deep sleep.

I unplugged my phone before I went to bed to see how much it would drain overnight. I only slept for 5.5 hours. My phone had lost 16%. Is this normal?
I was connected to wifi, only thing I had syncing was Facebook for every 4 hours.
I forgot to screenshot the cpu times, but it spent a majority of the time in deep sleep and 384.
Also, what do the red bars mean in BBS?

Try disabling WiFi as well? Im guessing you dont need Facebook to sync while you sleep, just refresh it when you wake up. Noticed you clock down to 384mhz while screen off. odd how still took away a lot for only 5 hours.

I dont think clocking down helps that much. it doesnt stop the same processes from running, and it takes longer to run them with the lower processing power, especially when the phone has all night to do it /
According to your screenshots you have posted, that kakao talk app is in wakelock, keeping the phone from actually sleeping. Although the other stats seem to contradict this i would be willing to bet this is your problem. I would either disable it from syncing in the app, freezing the process, or somehow prevent it from running. I would put money on it improving battery life drastically. I cant be sure of this as i dont use betterbatterystats but i would suspect the red bar is the time spent in wakelock, while the cpu is supposedly in deep sleep.
That doesn't look normal. I get less than 1%/hour overnight. Though I don't use Facebook or Facebook app. I do have 2 Gmail accounts on auto sync. Weather widget sync/hour. Field trip and Google+ sync enabled and wifi is always on when I'm at home.

Definitely not normal... I get about the same 1% an hour overnight.
I'll give it a shot tonight. Thanks.

I've noticed recently that when using the torch on my phone the phone doesn't go to sleep, in fact it keeps running at 400MHz. It definitely didn't used to do this because I could leave it on for hours andit would hardly drain the battery. Now it shoots ddown.
Any ideas why? I'm using Omega 9.1 with Redpill, whatever the latest is. The same happens with the status bar control or tesla led.
Any ideas about this? Strange that turning the torch on makes the phone stay at 400MHz. Also when using the status bar Assist Light function the UI crashes if auto rotate is on and the phone turns.
Well it's not the Redpill kernel. I just flashed Perseus and it's the same. Seems it's stuck at 200, not 400 like I thought earlier. I might try the newest Omega to see if that helps.
It might not sleep (which imo sounds normal since it has a task going on)
But leaving your flash on for hours cannot be good for it.

I'm fairly sure it didn't before but I might be wrong. I noticed my phone warming up while using it in work during the week (when the electric was off) which it definitely didn't do before.
Can't see any reason why it would be bad. Plenty of LED torches out there, it'll just use up the battery a bit.
No it's not bad. Even if the flash goes out for excessive usage it's pretty cheap to replace. But the device shouldn't go to deep sleep, it's not only a torch, it's an app running, that's why it could never go to deep sleep, normal.

Fair enough. I may have been getting mixed up with the FM radio. That deep sleeps unless radio information is turned on. And I was using the torch at the same time so may have got mixed up possibly.
I've got my 2013 Nexus 7 last week and i unlocked the bootloader and rooted. The battery used to be amazing but last night it drained 30% with wifi off, i checked and it wasnt going on deep sleep. Tried cyanogenmod but it doesnt gets in deep sleep too. Anyone else?
Install any apps?
I think there are programs that can monitor your tabs deep sleep and list which apps are keeping it awake or waking it up.
I'm running CM Kanged and just checked mine. I have about 89% deep sleep state.
Is something running in the background? How are you seeing deep sleep statuses? Or you just going by battery life/battery life?
Maybe a new app update?

No apps are causing the wake lock because I factory reseted it. Besides, I used better battery stats and the tablet was being wakelocked by the kernel, specifically this service:
