Not sure what wake locks means or even of this means that my phone is draining battery quickly? Or what I can do to prevent wake locks? Thanks for any feedback!

bam_dmux_wakelock - What is it? How do we stop it?

I lose 10% an hour (sometimes more) doing absolutely nothing with my phone. I check battery stats and like 98% is screen.
Question: how can that be possible if the screen isn't even on ?
I have tried everything. I'm running CM10 stable (which is supposed to be good for battery life)
10% an hour? This is a joke right? I have like no apps running. I even tried using apps that put the phone into DEEPSLEEP as soon as the phone/screen shuts off -- meaning every app is closed.
Nothing.
Any ideas? please help i love this phone but im going through 2 batteries a day and im not even using the phone that much.

My note was draining battery like crazy even on power saver mode, it would drain like 10% during night on power saver.
I did a factory reset it seemed to fix it for a day and then now it is draining again fast, I have all power consuming things shut off I don't know what else to do.
If there is one more tip for this would be really useful.

Some application is messing. Depends how many you have installed, try disabling them and then run each one by one...

That's a good start, 10% on power saver could be a lot on a phone with no apps, but if you have lots of apps its not that much, even on power saver some aps may be accesing the network, if you are connected to a wifi that would eat some battery as well.
If you added no apps and this happens then it could be a bad battery, unlikely but stuff like that happens.

Remember to sign out of apps like Google+, YouTube and Facebook, if you are signed in. If I notice quick battery drain, I'm often still signed in.
I dont know if the battery is bad or im missing something that is draining it

Is there a way to know if I have a bad battery please? I'm really concerned.

Unfortunately, I believe the only way you'd be able to really measure the mAh of your battery would be to compare with another of the same.
Can you post a screenshot of your battery usage?
Might help us narrow it down a little. Sounds like a wake lock but could also be due to terrible cell reception
Sent from my GT-N7100 using xda premium
Do you know your device and android fairly well? I am guessing its a combination of the above stated bad reception and your os & apps update schedule. There is alot of way to save power by going through and changing your notifications and app updates, as well as various settings on the os (ex. Switching to airplane mode @ night or at least turning off your data) so that your facebook isnt uselessly refreshing at 2:18am to see what club steve is at while your sawing logs.

I don't why the music player is using battery although I didn't open it once since I took it off the battery and the previous charge had the same thing too the music player was second on the list

I have another questions. when I'm using this rom the battery goes fast. How can I keep the battery from draining so fast?
Best way to save your battery is to turn your phone off.
Okay enough joking. Jelly Bean is a battery hog to begin with. Things that help would be under clicking your CPU, turning off things like 3g Bluetooth WiFi gps when your not using them. There are some battery saver apps that will do this for you when ever your phone goes to sleep.

Is there anything I can flash to help the battery?
What is Power Manager Service and deleted wake locks that is keeping my phone awake. Running KT747 Linux 3.4 Jellybean 4.2 4/19 build.
It also says Google Maps kept my phone awake for over an hour and messaging kept my phone awake for 3+ hrs too..
I only got 23hrs on a charge on my extended battery. What's going on!!??

In maps, you can go into settings/locations, and uncheck all that stuff that lets google monitor your location while you're phone sleeps, this resolved my maps wake lock issue, not sure about the SMS one.

Tap the little orange icon to the right. It will take you to the browser and explain what power manager is. It's likely due to push notifications. You can check what's doing this under partial wakelocks.

Do you have active monitoring enabled in better battery stats? When I had that turned on, that was giving me the most wakelocks due to power manager service.

How ironic would it be if Better Battery Stats was the cause of worse battery life lol... but anyways I did what Luigi suggested and got this:

BBS doesn't consume much battery at all compared to others, unless of course if you have the app actively monitoring but the option should be Unchecked by default.
Also, as the page to the link states, in order to resolve any of the wakelocks causing the PowerManagerService issue you must "Use "Partial Wakelocks" to drill down the applications / services causing wakelocks".

I've been seeing some problems with my battery, specifically deep sleep.
It just keeps waking up and never really sleeps. Screen doesn't turn on, but there is some sort of lock. Can anyone help? Thanks.

Try running Wakelock Detector to see what is causing it not to sleep and using Titanium Backup to freeze whatever it is, see if that solves your problem - if it does, either remove it or selectively freeze and unfreeze using TiBu.
I'm guessing at least some of it is your apps automatically syncing.
You really do need to provide a bit more info though. How bout a screenshot of the main battery screen, and tell us the total screen on time.
Better Battery Stats may help you out as well.

I'll try the wake lock detector. This is another screen shot from the same battery life. Now down to 6%. Screen tube is around 1 hr 50 minutes. The last post of the photo is cut off but it's maps amd media servers.
