Set CPU governor to performance. Turn on all your radios and set brightness to 100%. Stream high def YouTube videos over 4g network. Use YouTube modded HD apk for faster battery rapeage.

High brightness, turn up min cpu clock, run apps that are hd and consume data (maybe a few at once)
Can I just ask why? Are you trying to benchmark ROMs or something (curious )
Oh, turn on gps, blue tooth and wifi making sure they are constantly scanning too

I have a similar question, but I'm looking for a jelly bean ROM that can deep sleep.. it seems the ones I've tried are unable to do it.

Battery life is horrid, am I missing something?

I'm running the stable cm 10.0 build with lean kernel. Brightness at half. From these images I'm barely achieving 9 hours with less than 3 hours of screen on time. I'm confused, I thought this rom/kernel combo was supposed to produce great battery life? Can someone help me. Thanks.

Calibrate battery if that's a new ROM give it a few days. My phone sucks battery no matter what kernel or battery. Just ordered an extended one a few hours ago. Hopefully, by the time i move to the fifth generation galaxy device, this retard battery issue will be solved

If your are planning to get a battery extension i suggest get the 3000 mAh of samsung this Jan 5th that would increase your battery life up to 49% (i read that here in XDA idk where is it but its true ) and also try TRINITY kernel would be awsome if you done like it you could revert back to lean - its only a suggestion
EDIT:
Is this your 1st battery cycle in this rom? usually that is normal the following charging cycle would be stable from what you expect

Been using this for 2-3 weeks now I was hoping it would improve but I
it hasn't. I'll give trinity kernel a try, thanks.

I would go for an extended battery but I need a case on my phone, that's the only thing holding me back. It isn't new, I've been on this for almost 3 weeks.

If you need the extended and a case, look for the seidio active extended. I did about 5 hours of research to ensure i get what fits me best.

My girlfriend gets 30 hrs+ on her phone with average usage while I get approx 16 hours with barely using my phone. It's crazy how much it varies.

Sent from my SGH-T999 using xda app-developers app

Calibrating is useless, its a bunch of snake oil. So don't even bother with that.
Sounds like you need to check for a bad app preventing your phone from sleeping, otherwise flash to stock and re flash.

Brightness at HALF? Why??

Etabindu another
I went with the qcell extended battery, currently running the Aeonfluxx v6 rom. On heavy use days I usually have 50% battery left. My stock battery didnt last 6 hrs before. The sg3 is my second Samsung phone, and both sucked with battery life.

Try a touchwiz rom bro... might save you some battery. also less widgets, check what apps are running during sleep mode and my favorite
Just carry an extra battery <---- problem solved

I found that cm10 roms do not give a good battery at all no matter which rom i tried... So i ended up flashing paranoidandroid and ive noticed a huge battery gain its hard to set the rom up because it has tons of settings but once its done its great !!

[Q] Best Battery Life

What's the best CPU configuration for the best battery life. I'm currently using 384-1512mhz with smartassv2 and I wonder if that's the best calibration. Thanks in advanced. I've been losing quite a bit of battery lately and I need some recommendations.

You can do most of the tasks with 1000 with gs2...nos helps to reduce lag. Like l said with my setup...no lags

With Tweaked I easily go a full day with no charging. Frequently have 30-40 percent left when I plug it in at night before I go to bed.

Try using Temasek's unofficial CM11 roms with his kernels, you can look for him on twitter "@temamsek71". I get GREAT batterly life and performance, and LOADED with features.
