I have changed my firmware from 10F to 10H as I heard that it is much better. I rooted it and then reset it to factory settings and I deleted some of the bloatware. I used LG gearbox and set the CPU speed to 1000mhz on two cores and used this guide. http://forum.xda-developers.com/show....php?t=2048315
In additions, I installed fast dormancy toggle from here. http://forum.xda-developers.com/show....php?t=2021248
Yesterday, I used the phone with light usage such as browsing for a few minutes that's all, but still the android system was on top, I hardly used it why is this?
On the CPU it shows that it was running on 51mhz for more of the time than deep sleep, that must be the reason why the battery had been draining.
android system is more than one app, is the system it self...
Its logic why is on the top
yeh but even wen my phone was not in use how come it was hardly on deep sleep? compared to the galaxy s3 this battery is much worse as on s3 the android system is below the screen and screen is on top for usage. on the s3 when the phone isnt in use it is mostly on deep sleep.

Disregard this, the guy is wrong. Your phone should be in deep sleep most of the time.
Could you please obtain "BetterBattery Stats" or a similar program to post screenshots of your kernel and partial wakelocks? This would help us figuring out what is wrong. My friend has the same phone, and Android system is on top for him too most of the time. We are still trying to find out what is going on.

He's right... Sorry, my mistake
When in deep sleep :
In first place should be "Cell standby" and after "Phone idle".
It's what I have in mine...
After 9 hours my battery drain was 1% in deep sleep.

Check the CPU Governor ,, for dual core we set it "hotplug" but about quad core I do not know .
But mainly the problem with governor ,, governor means something like profile . It controls the CPU frequency to get performance or powersave or both of them .
To change governor install any CPU app and you will find it .
Search about governor with quad core in google . Sorry my phone is dual core (Optimus 3D) .

The Governor has no influence on any app or system process holding a wakelock. The governor merely controls the way the CPU frequency is scaled depending on load conditions.

Yeah . I know
The governor controls the deepsleep which makes system off
So by the governor can enter deepsleep then the system will off .

maybe phones battery isnt calibrate. let battery get empty completely & charge it again. repeat this job several times. then use battery calibration & easy battery saver.

did you make sure your apps running don't keep your phone awake? and that the phone does go into deep sleep?
a bit off topic but my problem is that the battery has been stuck at 24% for the last 12 hrs, I've not been using the phone because the earpiece speaker is broken so waiting to get it repaired. I've tried rebooting the phone and still at 24%, I'm going to play a video until it drains the battery and do a full charge. battery info shows the phone has been on for 2 days 11hrs since last charge on standby most of the time.

i charged the phone yesterday night now the battery is still on 100% with no use all day. if i open wifi or start for example an app the battery goes down like a countdown.whats the problem then?

There are plenty of threads concerning battery life. Search and read. Download "cpu spy" from market so you can see if your phone goes to sleep allright.
Uninstall failbook or atleast keep it from updating every three seconds or so. Etc etc etc.
I have installed cpu but can u tell me how it works? Very confused on how to see if theirs a problem. My reboots i think are from facebook so ive deleted that app.

To use cpu spy....
Reboot your phone... Turn off the screen for few minutes... Then check deep sleep state in cpu spy.....
Has anyone tried the bigger batteries that you can get. Spotted some on eBay and amazon and wondered if they were any good.
I knot with some you get a replacement back as it increases the thickness of the phone but I don't know if this is a worthwhile trade off.

I used stunner and I used to get 2 days plus with normal battery with moderate usage. Now iam getting 1 and half day with AOKP.
For CPU spy - see if u get deep sleep.
Also chk out with Badass battery monitor which app using the most.
Lol first analyse root cause. In an hour of non activity and not on charger pecentage deep sleep should be approx 80% two hours 85-90%. Figures based on clean rom, nocrapware and no rediculious settings. Thats one, two how long does your battery last when using phone nonstop? 2.5 to 3 hours is normal. 3-4 then you know what you are doing 5 youre a guru.
Lmao
If your cpuspy figures are lower then above then with better batterystats you can find kernel and partial wakelocks. Google them and find out whats keeping your phone awake.

I don't know how I did it but the tab is now on 125 Mhz when I don't use it. However, CPU Spy says that it does not go into deep sleep. How can that be and what is the difference between deep sleep and simply going to the lowest CPU frequency?
Cm9 stable release without gapps install is giving me battery backup almost same as overcome.no more over heating,lags or bugs.perfect build.
nightly build cause overheating n fast drainage in my tab. however didnt try latest versions as after stable release i didnt flash any other rom.my main concern use to be battery life so always come back to gb.bt now 2.3 is outdated for me.

Depends on what you did during that period.. If the processor was running at MAX frequency the entire time, yes thus might be normal.. Also as I notice from the screenshot, the screen is always in in that time frame.. So you deduce from this

No. It's broken. You should send it to me.
Hi,
Thats an abnormal drain. Try restarting your phone and seeing if the problem persists. Also note that the ROM you are using is still under testing and not a finished product so might experience some difficulties. Consider shifting to a more stable ROM if problem persists.
Having said that, battery drain will depend quite a lot on what apps you have running in the background and your settings.
Best way to analyse the situation is by installing an app called 'Better battery stats'. Its by a XDA member and if i'm not mistaken he offers it on XDA as free download. Try to see what is causing partial wakelocks and kernel wakelocks (your phone should be on deep sleep mode for the majority of time). Try to see what MHz is your processor running at (it shouldnt be in the 1400 range for too long unless you are playing some heavy duty games)
Also try to search for threads on 'wakelocks' on XDA to get more details on this subject.
I have experienced close to 10% drop in 1.5 hr in stock ROMs and around 15% in five hours on CleanNote ROM in idle states with lots of background apps disabled.
I'm having troubles with my battery, it drains too fast! I've used battery calibration tools, I deinstalled samsung push notifications, I'm using juice defender, screen brightness is around 30-40%, but the battery still gives me about 2-3 hours of screen time, or if I don't use the phone that much, still drains to 10-20% by the end of the day. Any suggestions, please!

well,the battery problem in my case was the Dropbox app...it was keeping my phone awake all the time and the battery lasted 20-22hours tops...
i uninstalled it,restarted it and all came back to normal and by normal i mean 2 days of medium usage,sometimes even 3 days...the battery drainage overnight(6-8hours) is between 3-5% (with wifi and 3g off)...
so,im pretty new to this android world,but check out your 3rd party apps,maybe some of them is keeping your phone away from going into deepsleep when you dont use the phone...cheers

as i mentioned im fairly new to android world, but if u got to settings>battery and click on the graphical picture,below the graphics that shows the battery usage,you will see info about GPS-on,Wi-Fi,Awake,Screen On and Charging...my guess is that "Awake" should not be full blue bar all the way, since when you dont use the phone it should not be awake all the time...
at least this was my case with my Dropbox app,but i dont know about you...if your phone was OK for some period of time then it suddenly changed its behavior,then i guess you should ask yourself which apps you have installed lately,maybe some of them is causing this...uninstall the latest apps,restart your phone and see if that changes your phone back to normal(you can always install those apps back if this doesnt solve it)...

Hi, you could try with this nice app called Tegra Overclock. I've been using it for quite a long time now and I really like it. It's very simple and you can REALLY set how many CPUs you want online + there are also some other options for OCing etc.
Oh and btw, I just tried that app from the HTC One X thread that you pasted and unfortunately, it doesn't do the job. :/

You need to set up min/max cpu that way u wont be stuck on max cpu speed and overheat your phone.Tegraoverclock is fine but i am kinda used to SetCpu app.Download cpu spy from market and watch deep sleep that way you will know whats going on with cpu all the time.BetterBatteryStats are fine too.
