What does everyone find is the best kernel for battery life?
Sent from my SGH-T989 using Tapatalk
personally, i don't think you need to be concerned much about battery life
i'm surprised myself, as i'm a heavy user, and this phone can last very long time on a single charger, pretty much a full day without the need to top up the battery
and that is OC to 1.8 Ghz
my old Nexus S wont last 4 hours with the same usage i give to the T989
it really depends on usage there isn't one golden battery saving combo in my opinion
I would like to know as well because that would be my main reason to want to root the phone.
I'm mainly just looking to get rid of bloatware and better battery life, which rom do you think would be best XDA?
believe it or not, the stock ROM in this version of the phone is very decent for battery life
you can find tune it with SetCPU if battery life is your goal, and NoBars, and optionally JuiceDefender
What about all of the uv kernels? I need to squeeze juice as i'm a power user.

Im getting awesome battry life and even better performance on BeastMod v2.0 with Synergy 0.03 Kernel. With SETCpu i have it at 1.6ghz MAX and 384 Min with LAGFREE scaling. Buttery smooth!

Seconded. And I didn't even OC.
I am also running:
1) Juice Defender Ultimate
2) SetCPU for screen off profile
3) NoBars Battery Saver
This combined with any bloatfree ROM will net you awesome battery life on this phone.
what setting are you using for screen off profile in setcpu?

I use to use 192 min 384 max, but had some SOD problems with the new BeastMOD 2.0 rom, so I used 384 min 432 max.
What about this new phantom ROM?

BUMP......
Juggernaut 2.0 with Jugs 0.3 Kernel
So far for system stability this is an awesome combo. Im still going to wait a few days to talk about battery life.. i spent the last 2hours texting my girlfriend and it drained 50% of my battery.. so yeah hoping the next fews days things will pan out.
2 users reported great battery life with it...
I'm also using BeastMod 2.0 with the latest Synergy Kernel 0.05. I use SetCPU to do min 384 max 1.5ghz (not overclocking) with lagfree governor. It is incredibly fast and my battery life has been solid. I only have one profile on SetCPU which is 384 min 384 max when screen off. All is well here.

What do you consider. Im using 0.05 and this phone is chewing up battery..i estimate 6 hours tops for mine with this kernel...itsjust so fast tho that i cant say no.

Looking for some battery life here. What would you recommend?

Honestly, with the stock CM kernel I stretch out 18 hours easily with heavy usage (non-stop texting )
That is of course with NO profiles @ 806 MHz using the ondemand governor. If I need more power I just simply crank up the processor, no need to stay OCed all the time
With that said, 806 MHz is perfect, I experience no lag at all. So there really is no need to stay OCed at 1.5MHz unless you want to kill your battery
Hehe, I actually love you for UPGRADING from a crap NS to a G2

I got some lag on ADW EX at the stock speed, so I decided to melt it away with buttery OC goodness. I'll actually see how it lasts today, and if it's killing me I'll try clocking down until I get something acceptable. I was just wondering if there were any especially good UV kernels or anything of the like.

What kernel did you end up going with?
I use pershoot's kernel and get pretty good battery life for being overclocked at 1.5ghz.

Is the one on ROM Manager compatible with CM6?
Tomorrow is the last day to return my Galaxy Nexus but i really don't want to. But the battery life is killing me. I always keep the 4g off unless. I am downloading something.
I figured next step is adjust the kernel. I came from a Droid X so i have never played with kernels. I have setcpu installed and have a read forums but just can't grasp what to change in there that makes a difference. Like when to use interactive, conservative, ondemand and performance
If anyone can share screens of their setcpu settings and setcpu profiles that get them great battery life it would be much appreciated. I'm a visual learner lol. Or screens of the franco kernel app if i should invest in that.
My setup :
Latest of AOKP
Latest franco nightly
Samsung extended battery

As per franco himself...
SetCPU profiles not at all, they only hurt the device's performance/battery. Everything that is needed for top performance/battery it's already set by default (in my point of view of course).

Post a log from betterbatterystats (app), the battery settings windows, and cpuspy.
Franco recommended conservative last time I checked.. also how much are you getting for screen on time? If you're only on 3G you will probably only ever get around 3 hours with the stock battery.. don't make any profiles in set CPU with Franco kernel he strongly advises against that.
Also last I read he had the minimum frequency at 700mhz

hello i have right now beast mod 4.2 and , i am wanting to under clock it to get about 1 1/2 days out before it hits 10%. if some one could help me with the M.V value i am currently using antutu cpu master pro from 192mhz to 1.836ghz

Im not familiar with antutu. Does M.V have to do with the voltage? If so be careful about lowering it much more. Because the kernel that comes with it is already under volted, and your phone could go bonkers. You need to lower the CPU speed to about 1.118. You wont notice any difference in speed. Im running BeastMod and I dont use any off screen profiles, synergy kernel goes into deep sleep with out any.
I have git my goal but now my phone is slow I am running at 450!-850 but I would like to run 700-1200

Yes it does mirror volt is what you less for under volt do I think Mr. X could tell me

Which kernel do you think gives you the best battery life on your CDMA Gnex?
Please post the kernel/ROM you are using as well. Thanks!
I've tried all and I'm gonna have to say lean kernal does the best for me

I have tried all too and I find there is virtually no difference when I'm using either AOKP, Black Ice or DroidTh3ory's roms (yes I know they are all essentially the same!). My favorites are IMO's and Franco's kernels due to their smoothness and color options.
Leankernel for sure.
Lean kernel

Kenerl Options As Well?
For those suggesting what kernel they think is best, would it be good to include what options you have configured that lead you to the battery savings?
+1 for leankernel, but certainly not v2.5.0 from March. 4.2.0 instead.
Air kernel has literally doubled my battery life compared to all other kernels on jb. With it I get the battery life is was with ics. 1200 max 234 min smartass2 governor sio scheduler

I've been using the latest James Bond kernel for 4.1.1 and get around 3 hours of screen time and haven't really got to test the full standby time. I was at 22 hours of standby this morning with 77% battery left. I have my CPU set at 1.2ghz with the interactive governor and have been using the cfq scheduler (default setup). I think I'm going to give that air kernel a go and see if I can get better performance.

What are your favorite settings and governor???? Which one you recommend for best battery life?? Which UV and OC works best with your rom???

What kernel are you using? I usually uv by -25mV each step and start from there. In the Original Android Development section, Ktoonsez has a kernel and on the OP he lists what his voltage settings are....or at least a decent starting point.
I am currently using Agat v0.3.2 kernel, no OC, ktoonservative govenor with the deadline schedule. With moderate to heavy usage I can get just about a day out of a charge (usually with about 3-5 hours of on screen time).
