Extremely high battery drain in CM7 - Optimus One, P500, V General

Hi there.
So I flashed Cyanogenmod7 to my Optimus One
I'm very happy with it, however, there's a problem
On official froyo and 2.3.3 official gingerbread, i had the data connection ON and wifi on,too.So whenever I left the house, it would switch to data.And it wasn't on 2g,it was on HSDPA. Anyway, the battery consumption was barely noticeable,especially in standby mode.
However, if i do the same thing now, on CM, the battery drain is enormous
Wifi does not consume a lot, but whenever it switches to mobile data, the battery consumption is 10% / HOUR in IDLE mode, using the Smartass governor 245-600MHz, making the phone useless. And this is the consumption in standby mode...when I use it it's a lot worse. This problem makes me unable to use the mobile internet without returning home with a dead phone.
Is there a fix for this? Does anyone have the same problem?
Yes, i have the latest version of CM7, for my model,p500. Is it because of the old baseband?
Thanks in advance for any help

i encountered this for the first few days when i flashed to CM7 too
battery drop so quickly even when its at standby mode for 8 straight hours.
but after using for weeks, the battery begun to last longer, can last up to 2 days with light usage (some texting and tweeting)

---

im getting minimum of 4 days battery on cm7 -.-

Try this
1. Charge your battery to 100 percent.
2. Reboot into recovery and wipe battery stats.
3. Completely discharge the phone till the state it switches off.
4. Charge again.
Maybe it will help.

I have never understood how or why this should work. Maybe somebody could elaborate this a bit?

@OP: Which CM7 version? What kernel?

---

This is not usual.
I'm getting few days with CM7. Try calibrating the battery with Battery Calibrator from the market.

---

I already calibrated with the app from the Market
Charged to 100% ,Calibrated,discharged to 0%,then fully charged.
I did this twice.i dont think this is the problem.
I did a test :
Yesterday,when I first saw the problem,i had data enabled.I got 10 hours of battery life with the phone Idle (locked,yes.)
Today, i didn't enable data.I had 99% battery after 2 hours of idling. I guess that's normal.
So, i already know the problem. the data connection does this to the battery,but why?... as i said,when I was using the official froyo and gingerbread,i had both data and wifi enabled and i had absolutely no problem with battery drain...

This is called battery calibration.Whenever u flash a new rom,u need to calibrate ur battery so that it wont show u the stats of ur previous rom.If u dont wipe battery stats,sometimes the phone may switch off fue to low power at 15-20% or strange things like virtual increase in battery % by 2-3 %.So it is required to wipe battery stats,so after booting the phone,a new battery stats file is created and it wont give false info.

There's no need to completely discharge a Li-ion battery, it can in fact damage the battery.
Proper steps:
1. Charge your battery to 100 percent.
2. With phone still plugged in, reboot into recovery and wipe battery stats.
3. Reboot phone
4. Wait for phone to completely boot up then unplug.
5. Calibration complete

Hmm.. that's unusual. By the way, 6.6.1 or 6.5.8? And also specify the kernel you're using.

flash newest goldenleaf kernel; -> http://forum.xda-developers.com/showthread.php?t=1227682
disable gps;
disable wifi;
set interactiveX as default governor;
set minimum brightness;
disable data;
use 2g instead of 3g;
disable bluetooth;
make sure that your installed apps aren't killing you battery (via android config/view battery status);
reboot phone could help sometimes.
ps. the new baseband consumes even more battery

wait....better signal=more battery consumed?
New baseband for me is lesser in battery consumption than in old baseband

Wait !!!!!if its only bcos of data i have a solution!its because unwanted apps n process use data n consume charge ..so go to market --download droidwall ..and manage apps tmwhich you require connectivity for
Trust me it sounds silly but you ll surely see much improved results! !

I checked for apps that consume internet.I don't have any.Facebook would be one,but that's all.
I read something about the older versions (official ones) of the firmware using something called NETMGRD to reduce the battery drain caused by the APN being on..
what do you guys think about this?
And also,since you asked about the kernel :
2.6.32.42-franco.kernel.v18
Cyanogenmod 6.5.8

If i use 2g continously i get batrey lyf of 3.5 hrs..
Is this normal?

im not sure but according my exoerience even the android sytem sometimes uses internet..
once when i checked my battery usage is saw something names MEDIA SERVER poping up!havent seen that before and i was having say 5%battery darin in 10 minutes with screen off and wifi connected n active!!so then i got droidwall and blocked everything except for ones that i needed like market,xda,browser etc!and i saw that thing named media server go down n my battery lasted longer..had about 1-2 %drain with 3g active and screen off!else it usually will be higher!

That's pretty outdated kernel. Flash a new one.

I get good battery life using the 2x Battery program that cuts off the 3G data when the screen is off and opens it at a set time (every 30 mins on mine) to check for email etc instead of constantly when the screen is off.
One of your major killers i see is the constant WiFi, with it and GPS if your not actively using them turn them off.

Forgot to add, the rule of thumb is anything that uses a hardware component uses battery power.
GPS
Wifi
Cell Radio (2g,3g,Phone)
Screen
Vibrate motor
Speaker
It takes power to make those work so the less you use some of them the longer the battery lasts.
Anyone that drives at night knows the effect of turning on the wipers, the radio, the lights and the blower fan on high to clear off the windshield and seeing the voltage gauge lowering from the heavy voltage draw.
