battery draining drastically

I have been using TheMyth Basic rom and getting very low battery backup. even with data mode off and underclocked at min122-max480 mhz, the phone gives just 3 hours of music playback. Is the battery faulty or poorly calibrated? Help!!
Screenshot is when i used Whatsapp for almost 2 hours...n it was almost low :/

Check using CPU Spy to see if you even have deep sleep when idle (not doing anything of course)

Try this...
1. Reduce your Screen Brightness.
2. Wipe battery status through CWM.
3. Uninstall any bloatware.
4. Use 2G (GSM Only) networks.
5. Flash another rom(at last...).
Then your average batterylife will increase.

Android system battery drain is this normal?

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.

Even in deep sleep the clock is working, the alarm, keys software...
Like when we are sleeping, heart keeps beating, etc...
That's why it's logic to be on the top

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 .
I know what I say , I do not post things I'm not sure about them

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.

battery
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?

great news:CM10.1 just fixed the lag issue

the title speaks for itself
those who waited for this can flash the MAY 25th version of cm10.1 to see Skrilax_CZ 's amazing work

Thats great! but wouldnt it be better to have a working camcorder? Just saying. Or are there are any fixarounds for video cam?

and what about the battery drain? nobody likes the battery drain, but we appreciate the work, thanks!

Yes, lags are disappeared in menus on high scrolling speed, but if you will scroll menus or browser window with low speed - there will be glitches. You can easy found such behavior in settings of Messages application (there is white background). If you will scroll settings with low speed you will see noticeable glitches.
But anyway, if you compare new build with older - there huge difference in rendering. Also, lags in 3d applications is gone.

battery performance
battery performance is too poor in this rom. it lasted only 6 hrs with moderate use (almost 70% standby) anything can be done?

try changing cpu clockspeen and i/o settings... change i/o to sio and cpu governer to powersaver when less used and interactive while using graphic apps like games etc... hope this will help you

The battery drain is due to high standby/sleep current. It never goes below 15mA.
I've tried several governors with no success. I'd assume that the kernel is not fully optimized yet to put CPU in sleep mode or be able to turn one of the cores off during sleep. It does it with stock ROM where standby current is around 5mA on average.

Someone who works on kernel should fix it at some point. We had same high battery drain in HP touchpad CM10.1 until it was fixed.

[Q]How to enable only two cores? (CM ROM)

Hi all.
Dont know if this is a stupid request
I am on CyanogenMod based ROM and i want to save battery (maybe) disabling some cores of my O4X...
I read this
http://forum.xda-developers.com/showthread.php?t=1804461
but not working on CM ROM so...
I ask you!
I read also this 2 threads but I dont know if they are only for htc one x
http://forum.xda-developers.com/showthread.php?t=1630200
http://forum.xda-developers.com/showthread.php?t=1652136
There are tricks to enable only 2-3 cores or something like this?
For CyanogenMod of course!

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. :/

No problem. I hope that It will help you with your battery life.

also cpu tuner and trickstermod do the job pretty well. If your aim is to save battery check cpu tuner out

But seems that trickster mod dont save those settings for me...
Multicore Power Saving
always set to 0
Max Active CPU core
always set to 1
No way to fix them (various rom and kernel tested).
AND
Seems that tegra overclock fired up my CPU (CPU never goes under 1000 Mhz but always on max)
my phone after few minutes reboots in bootlop cause the temperature reached !
I reinstalled the ROM!!
LOL experience!!:banghead:

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.

[Q] Z1 keeps rebooting after unlocked bootloader and rooted

Hey,
My phone keeps constantly rebooting itself whenever I open some heavier apps like, videos, games, browser and such...
Got noFrills cpu on on demand.
Any help?

I bet you have over clocked it too much, reduce the max cpu until you get a stable setup
