Is anyone seeing very fast battery drain? Currently running skydragons Dev edition ROM and kernel. Tried using greenify and juice defender to help mitigate it but not having very good results yet. Any suggestions?
Battery fine all stock.

Stock Battery Drain
I'm running Stock and i am having very bad battery drain. I installed CPU Spy and noticed that the CPU state "Deep Sleep" is never used. CPU is normally at 960 MHz and 384 MHz. I also installed GSam Battery Monitor and after a full day the Kernel and Android System 40% of the battery drain....
Is anyone else experiencing the same issue?
Give it a few days, let it break in

I have been using setiron's reoriented kernel for awhile now with the Voltage control app set at -75mV for 100, 200, & 400mhz and -50mV for all other frequencies. I am not having any stability issues and the voltages are sticking after reboot. However, I was expecting a pretty significant increase in battery life due to the undervolting and I have seen next to nothing. Battery life is not bad by any means but in real world use is pretty comparable to what I was getting at stock voltage.
people seem to be reporting really big increases in battery life, so I'm a little confused. have I not UV'd by enough? if that were the case I would expect to see at least some battery improvement.
I wiped battery stats/recalibrated the battery when I flashed. I do have BLN enabled, but my understanding is that this causes a really small amount of battery drain. any thoughts?
How much % of battery you loose after night|?
while idle with the screen off (background data enabled) I lose about 1-2% per hour. I lost 10% overnight most recently and I was asleep for 7 hours. that is about the same that I was getting at stock voltage.
all i can sya, is thst you losing not many %

If you are in a weaker signal area, then the cell phone radio is going to work just as hard no matter what the CPU voltage.

Battery drain can be a symptom of i9000 kernel and captivate modem.
Changing the modem and keeping 850mhz is a multi step process. I tried the kernel you are talking about but it's over rated.
if you want battery life flash a 2.1 rom and use unhelpful's kernel, 1.4.1 was the most stable on my phone but it doesn't have voodoo. 1.6 has voodoo and 1.7 has voodoo and clockwork recovery if I remember right. But I had random restarts, others did not report the same problems so who knows.
I would wait for captivate froyo source to drop. I'm getting decent life with cognition and no undervolting.
Edit after reading the whole thread your battery life seems normal, I don't see any problem, you can try more undervolt but test the phone completely. Make sure it doesn't freeze randomly, or on shutdown. Also test it with the charger plugged in, extra heat from the battery charging can affect stability.

Hey all 2X lovers!
Ive been thinking more and more of some overklocking here and Im running this ROM so I can overlock. Im running SetCPU for running different profiles and lovering CPU speed to save battery. I know it can overlock too with doing the setcpu.txt files but how do you increase voltage in the textfile?? Or can I run Pimp my Cpu at the same time as SetCPU without problem?
What speed/voltage is safe and draws not too much more battery??
And yesh Ive searched for this but didnt really found any good information..
I think use Pimp my Cpu only is better, it's because most x2' kernel developers suggested to use it.
I prefer stable rather than saving battery. If you having serious problem of battery drain, please wipe the battery stats while your battery is full(for make sure it's full, keep charging 2hrs after 100%)
Ok Ill look more into Pimp my CPU then
What speeds and voltages are you running? PMC suggests certain voltages at some overclocks, I assume you should follow them?

I'm using temasek's UNOFFICIAL BUILD 130 + temasek default kernel. Every time then my battery percentage reaches 20-30 % phone shuts down. with battery monitor tool i see huge battery percentage drop. then i turn on phone, battery percentage gets back to where it should be (screenshot attached).
is there anyone having same issue and knows how to fix it?
Boot into the recovery menu and wipe the battery stats. Or download the battery calibration app, let your phone charge to 100% and then calibrate it.

thanks for hint. will try.

Wiping battery stats has no effect on the battery life. Diane Hackborn, an Android Developer, has elaborated on this matter on Google+.
I guess you have "Pimp My CPU" running and it is set up to save battery when reached 30% or 20%. It would do so by clocking down CPU, undervolting or both. Your Device seems not to like low Voltage, slow clockspeeds or both and shuts down.
If you have not set up Pimp My CPU yourself, your kernel is maybe set up to do just that.
Set Pimp My CPU up manually to not go to the lowest possible clockspeeds and to not UV.
It's very saddening but this is the case for me.
I have battery saver app installed but it doesn't help very much.
Is there any good power saving tips or perhaps a ROM really good for battery life?
can I replace my TP's battery?
What ROM are you using?
fat n-creamy CM10
1) check your wifi sleep settings and ensure it is set to off when not in use
2) set your minimum frequency to 192 instead of 384. However some people have seen SODs when set at this frequency
3) Use better battery stats to see if there any wakelocks.
I am getting around 0.5% using JCSullins 20121216 CM10 build.
I've been running CM11 (feb 14 build) now for about 2 weeks with terrible battery drain during use. The phone gets really hot when i'm just browsing facebook or reading a news app.
I looked at the CPU usage and it seems it's either at max cpu, min cpu or deep sleep. That is strange first of all, it never or rarely uses the frequenceis in between. Then i took a look at the battery graph. When the phone is sleeping, the battery is holding really steady, but as soon as I start using it all hell breaks loose and the graph looks like an olympic downhill slope. The strange thing is that the main battery source is the screen which is odd beause on stock (With better battery life compared to this) Android System was the main battery killer.
I then took a look at BetteryBatteryStats. First thing i noticed: 50-50 deepsleep and awake which is pretty astounding.
The wakelocks are msm_hsic_host and PowerManagerService.Wakelocks. But this is strange because it's still pretty much a clean install.
So my theory is that the CPU governor is not functioning propperly and blasts to max cpu as soon as a wakelock is requested and when the phone is in use it also blasts max cpu. I don't know.. that's just what I think is happening with the data i have.
Any ideas?
