Changing CPU settings for better battery life.

I am hearing a lot about cpu adjustment, over clocking and script stuff for some extended battery life. I searched a lot but couldnt find any nice guide on this. I am running Juggernaut 5.0 with darkside mainline karnel . I am getting 8 hours of battery life. Want some more; since i am heavy user
Please help me on that.

try beast mod, its awesome for battery life.

I'm running Slickmod 2.4 with Gideon's UV script (no setcpu or anything involved) and I'm PRETTY sure I'm getting better battery life than I ever did on Juggs 5.0, maybe try that?

Undervolting/underclocking is what you need to maximize battery life. With that said, I get 20+ hours running Warfare rom/kernel.

I tried synergy kernel with juggs latest and the animations get pretty jittery along with constant homescreen roughness while scrolling. It's not slow, but not smooth. Was wondering what the best ROM/kernel combo is that's buttery smooth with the best battery life.
I'm using adw ex if that makes a difference? Tried with touchwiz and was the same.

Best battery life OST?

Looking for a solid ROM/Kernel combo to get the most out of my battery on-screen-time-wise.. I was getting around 2.5-3 hours with toro 23 but after flashing 25 my on screen times have been seriously depressing. I haven't changed any major settings that would have, or should have rather, reflected this.. suggestions would be appreciated!

I use the latest franco kernel and Foxhound rom. Good for me so far.

That's some pretty serious battery life right there... but what im really looking for is on-screen time. Can you get me a screenshot with that?

I recommend leankernel 2.4
ROM doesn't matter that much but I'm on aokp
4h over 1 day everytime

I recommend AOKP last build (#27 at the moment) and Popcorn Kernel from sonicxml for the best battery life.

This was 13 hours and 50 minutes on Eagles Blood 1.9 and Franco kernel 15.2

HOLY ****! nice. reaaall nice, i like it. was this on wifi the whole time? I'm going to try this set up. thanks.

I would recommend aokp or liquid (roms)
with leankernel or minimalistic which ever you prefer to call it.
I can about 5 hour screen on time with 3g.

Can we have screentimes please + brightness settings?!
Anyone can do sod all with a phone for a while and get long battery life! Eg, last week:
I would like to know what ROM Kernel combos are getting best screen on time! Thats the major power consumer...

AOKP M4 + Franco Kernal M1
Almost exclusive use of wi-fi
Low brightness
No extended battery
Majority of time spent browsing fb/XDA/reddit:
Edit: Btw, I literally drop 1% over night, so if I use it on stand-by this would last forever.

[Q] Best rom for battery life E4GT

Hi im looking for the best rom with the best battery life. i had one a while back i was on battery for 15 hours and still had half a battery left i took a screen shot and i was actually using my phone too! open to any suggestions just wanna see how long i can get this baby to last

The stock el29 rom.

Calks el29 not stock :O
Sent from my SPH-D710 using XDA App

what are you two getting as far as battery life

Blazer 4.0 or 4.1 rom. EL29 or FC24 Modem is Bo$$ for battery life.
Sent from my SPH-D710 using xda premium

FYI.. everyone has a different experience with modems.. one person may be best with el29 another may be best with FDwhatever, and as far as roms go your probably going to hear alot of blazer, and calks.. battery life also depends on stuff in your phone.. like apps and settings.. 3g, wakelocks, background data, wifi.. all that kinda **** will vary your battery life..
you probably already know this, but just pointing it out.. trying to help out around here. =)

Two days on charge, almost 3 or 4 hours of on screen time.

I've gotten the best battery life absolutely hands down on codename YMMV

I just went to calks e4gt 3.0 first time ive been on gingerbread since i got the phone bc as soon as i got it i went to ics lol. very smooth. calk always does amazing work. ill let you guys know how i end up and yea i usually dont mess with profiles seeing as how it already has a battery saver script but i usually roll with 3g off all day unless i wanna surf the internet a little bit then ill turn it on check fb..etc then turn it off drastic increase from having it on all day

I'm using blended ROM from from http://forum.xda-developers.com/showthread.php?p=20166744 so far I've had excellent battery life.

Wow that's nice. I could probably get that too if I uninstalled tapatalk and angry birds lol.
And I'm running cm9 too (shabbypenguin8-06). Lasted 16 hours before it died today with 3 hours screen time. Not too shabby imho (pun completely intended lol)

Think I've already cast my vote hehe. 1 hr 34 min screen on so far

Exceed 2 hours???

Anybody find a nice trick pass that screen time barrier??? Most people reach 2 hours and it seems no one can pass that barrier.
The only thing you can affect and make better is when the phone is off.
The farthest I've reached is 2h 30m on a light day.

HAHAJAJAJAJAHAHAHA

I check everywhere about exceeding 2 hours and everyone is like oh this rom is that and gives me 4 hours with such and such and such kernel
And etc etc
I get 2 hours on wifi or 4G LTE or just plain 'ol 3G.

I turn my 3G data / wifi off whenever I don't use it. I usually get over 3 hours, not using an extended battery.

I still reach only 2h and 10-30m if I do that.

I only get 2 hours if I have one of the three on.

I was on skankwich and the samurai kernel at the time. Currently running jelly bean and samurai but there are issues with deep sleep for some reason.
Lazy governor fiops IO scheduler I used voltage control to under volt and control the CPU. If you have been using interactive then that may be why your battery drains.

Can you prove it was black?
Anyways, I had AOKP B39 + Franco 196, and it was amazing. 5.5 hours sometimes, usually 5 hours as the 2nd post shows.
Usually never had data turned on for more than 30 minutes overall, but Wi-Fi was on for most of the time. CPU speed was at 192-1036 MHz. Never really got around to UVing, mostly forgot about it cause I got such great battery.

I get 3+ hours easily on my GSM nexus, I've heard that the battery life is worse on the Lte version.

3 hrs of screen time still 40% battery gsm running jelly bean ROM from ROM manager

Did I mention I use Verizon.
Of course GSM gonna stretch.

From 100% to 0 using continously, it takes my phone around 4/30 hours to discharge

Help me find a good kernel for jellybam?

I finally got rid of tw and flashed jellybam. The only thing bothering me in the battery life. It's worse than what i had in my s3. I tried using soap and dagr8s kernel. But no luck. Battery falls 10% for less than half hour on screen time with medium use of texting and browsing. What is a good kernel and what are your recommended settings with it , like governor and stuff.
Thanks in advance

Well right now misusing the kernel that comes with beanstalk and I'm getting great battery life. I'm just saying that support for jelly bam in this forum isn't there anymore. That is why I wouldn't use that Rom. There is no thread on here anymore for it. The roms in the original development all get around the same battery life and are all aosp

Yea, sorry that's what I meant. I am loving beanstalk and highly recommend it. I used to flash a new Rom every couple of days and I have been on this almost 2 weeks, which is like a record for me. And like right now I'm at 89percent with 58 min screen on time.
