I've had CM7 on my t989 since the day after alpha 2 came out, and I've never had any serious issues I haven't been able to solve.
I've been trying to track down what's causeing my phone to stay awake, and I can't figure it out at all. In the android battery usage, it shows that my phone is almost always awake when it's sitting in my pocket with nothing running, even after a fresh reboot. No relevant application shows up in either the 'partial wake usage' list or the main android battery usage list.
Is there a way to get more accurate information about partial wake usage or per application usage then I'm aware of? I'm currently using Battery Monitor Widget to figure this stuff out.
I could be an application I have installed that is causing it, but how would it be ducking the android battery usage monitor AND the partial wake usage list?
Anyone else experience something like this?
If you go to Settings, About phone, Battery Usage, what are the top apps?

Try Better Battery Stats. It has really helped me increase my phone's deep sleep.

There are apps there, but they aren't the ones that are draining my battery, considering none of them are the ones keeping my phone awake while the screen is off and it's idle.
There is battery usage going on that isn't listed on the battery usage page, which is why I made the thread.

I've used better battery stats, it exposed the same information that battery monitor widget does, just in a much less user friendly way.
What ever is keeping the wake lock, my phone isn't tracking it, making me think it's something in the OS, not an app I have installed.
I'm willing to bet its something with calls/proximity sensors. Is Android system 2nd on battery usage behind display?

Yeah, android system is almost always second, is there anything I can do to help that besides switch back to a samsung rom?
Is this happening with other people on CM7 alpha with this phone?

It happens on a bunch of phones with cm7. Not just this one. There's really nothing you can do about it. Are you getting that bad of battery life?
Sent from my SGH-T989 using Tapatalk
Yeah, the battery life is really bad sometimes, but other times it's fine.
So no one knows the cause? It just happens? I'm confident CM9 will fix it, mostly because they have the ground up reword the ROM to make it work.

The times its good is when you don't make many calls? Or your calls or later in the day? What happens is after you make a call there is a partial wake lock triggered by the proximity sensor. Pay attention to that.

Thanks, does restarting after a call solve the partial wake lock?

yes, thats what i did sometimes on my evo. i also like to do a battery pull at night before putting my phone on the charger. kills any crazy processes
no battery issue but i can't make calls.
Is this the kind of battery life I should be expecting? Completely stock and running Juice Defender. Thanks!
It looks like you need to apply the "Cell standby" fix. That won't help your actual battery life, but it will help your reporting.
Everyone is going to be different depending on usage and signal strength.
Your battery usage isn't that bad, but when I was running ICS I would be able to get over 3 hours screen time and someimtes 20-24 hours total life.
It really varies based on your data usage. To extend battery life, then turn off unused data connections. Adjust your sync frequency, and limit push notifications. Network data coverage also impacts battery life, so in areas that have bad coverage, your phone is going to be searching for signal more often.
Use CPUspy as well and see if you phone is going to Deep Sleep when it should.
Here's a screen shot of CPUspy. Hope this helps!

Your phone is not going into Deep Sleep as it should which is causing the higher drain you're seeing. Post what is using battery stats. Also, try to reboot. You said you were stock, so it could just be a random program that didn't close and is running in the background.
I would check your sync settings too.

Should I post a screen shot of partial wakelocks or kernel wakelocks? Thanks!
Sent from my SGH-T999 using xda app-developers app
Yes please do.
You have a rogue app that is prevention your cpu from sleeping.
What gives?

If your screen on time is not around 4+ hours then you most probably are not getting good battery life.
Post a screen shot from betterbattery with Processes and Since Unplugged as your parameters. Wakelocks are not the problem. You have an app constantly running that will prevent DS, so a Wakelock is irrelavent at this point.

I did a restart recently so this is all I could get. Let me know if this helps or if you want one since unplugged.

Ya no dice on that one. Just charge it up and run it for a few hours and then pull a screenie of Processes and Since Unplugged. I wanna set what it shows for your Android System as that is your main culprit.
Some things right off that I see with this last screen shot. First, I don't think that your JuiceDefender is working properly. Usually there is a Red, Green or Blue dot in the upper right corner of the shield. This is an indicator of your radio state. Second, that Revamped Nexus S live wallpaper will munch your battery. It's cool and I own it too, but it does cause some issues with battery, not neccessarily wakelocks though. Third, that Battery Monitoring widget is eating it up too. Not sure if the icon on the top-left is for that or not, but if it is in the notification area, then it is polling and is not caching causing drainage.
Those are just what I am seeing from this last screen. I am more interested in the Processes/Since Unplugged screen shot. Charge up and go get some lunch/dinner (depending on where you are) and come back later on after and post it up.

When I use my cell all the day NOT on WIFI, I get around 3 hours screen time (auto brightness - brightness medium most of time)
When I use my cell all the day with WIFI, I get 5 hours screen time (auto brightness - brightness medium most of time)

Heys guys I have a strange battery Problem
I am using CM7.2 Democracy and phiex kernel. I love the Rom but there is just one problem with my battery. When I charge my battery(with phone ON) after it goes to 100% I switched OFF the phone and the Green battery that comes when the phone is OFF shows that battery is about 80% and the battery is still charging. I couldn't charge my phone to REAL 100% with my phone Running . Also when my phone shuts down due to Low battery I connect the charger, while the phone is OFF, and the green battery shows that it still has about 30% of battery while my phone turned OFF Due to Low Battery.
What is the problem
Any solution??
Try to calibrate your battery..
I was at the same problem before and it works like a charm after calibrated
Hope this fix your prob.

I dont think U have to install anything to have deep sleep feature. I think its a feature of android OS that is already enabled!!

deep sleep feature is included in android os but its disabled by default.so you need to activate with no-frills cpu control app and it should be activated.

I'm just a noob here at xda, but sorry I don't think so. Deep sleep on Android works with or without No Frills. The only thing you can do with No Frills is to enable the deep sleep stats (in No Frills cpu stats) that are usually hidden...
@ abdullahaftab: if your deep sleep doesn't work you have something installed or working that don't make it works. Maybe is your rom, maybe it's just an app

I calibrated My battery according to the instructions but even then when my ROM says that battery is 100% charged, I turned off the phone and the green battery still requires another 30 minutes of charge until it says 100%. Why my ROM does not charge my battery to 100%??? =(
And for the deep sleep I deleted few apps that were in no use and after that deep sleep was working.
Any Solution to the above problem??
thats the calibration part.
after a long time the % given when the phone is on does not exactly much the real %.
but, this does not give a shorter battery life, as it will also hang on other values of %. just charge long enough and it will be full.

Ok It looks like I would have to carry on charging with my phone OFF to get 100% charging !!.
Another Question: I put my Brightness to only 25% but still when I see battery use Stats, Display is taking 70% of my battery . Why is that so??????????
Hey,
I have currently the Jellybam Rom with stock kernel and even before when I had the wicked Rom this would still happen. My battery usage drains fast and the battery always says it's awake even with the screen on. I feel like my battery is greatly suffering and I have no idea what's causing this.
I also have always had juice defender and watchdog to monitor my running apps but it didn't help. I uninstalled light flow music apps and juice defender etc. With no luck so I feel like it might be a setting or something I can change to fix this.
I have NFC and bluetooth off, sync off any hotspots etc off, just wifi (sometimes data) on and all other options such as brightness etc at the lowest.
Any help would be appreciated!

Some app or something is preventing your phone from sleeping. You should try betterbatterystats to see what it is. And seeing by your pics your phone is not going to sleep at all.

Ok thanks I installed Better Battery Stats.
Dont know anything about the app though.
Just wondering what stat I should use to monitor what is happening with my phone?
Should I use Process or CPU States? Kernel Wakelock?
And then how do I identify what the problem is?
Thanks
Any ideas?
Use partial wake lock to determine what's not allowing your phone to sleep.
Sent from my SGH-T999 using xda premium
For the past few days my phone has been kept awake for over a hour per day. I used better battery stats to find out it is due to the "powermanagerservice.wakelocks".
Does anyone know how to stop this wake lock or at least control it so it isn't keeping my phone awake and draining battery.

I meant Alarms screen after turning off Location. If it was off already, then go to Settings >Wireless >Advanced. Set "Scanning Always Available during Sleep" to Never. Also uncheck "Always Allow Scanning".
FYI. Typically such wakelock issues are posted on the BBS Thread and not as Device Q&A.
