Best kernel for battery life with Fresh 3.1.0.2?

I've never cared about battery life before because I'm typically near a charger however I'm going to the beach for a few days and will need my phone to last.
What's the best kernel/set up for me if I'm running Fresh 3.1.0.2? I don't care about performance, fps, mflops, etc for these few days as long as the battery lasts and the phone is stable. I have setcpu on my phone but don't really know how to use it.

The latest cfs kernels are supposed to focus more on battery life than performance. Do you underclock cuz that's a big help too.

I'm running Fresh and Netarchy's 4.1.8 kernel.Creating a set CPU profile for when the phones screen is off will increase your battery life quite a bit.My screen off profile has the CPU max at 245 ghz and the min at 128.You can also scale back your max from 998 mhz to around 500 mhz and save battery without your phone being so slow that its really noticeable during normal use.

Interesting. What kind of battery life do you get? I thought I read a while back that going below 245 was a bad idea. Guess not?

It's more stable with the newest kernels. I'm set at 245 min and max when the screen is off and I usually see a 1% loss every couple hours but I haven't paid a lot of attention to it lately cuz like you, I'm usually near a charger. Battery life while using the phone still isn't great but I kind of expect that from a phone like this. There are some good battery conditioning tutorials in the forum that help quite a bit too.

Here's my usage for the last week.I go off charger at around 7am and usually have about 70% charge remaining when I get home at 5.

Getting Better Awake Battery Time?

Sup guys. I no doubt get great battery life. Check out my screenshots below. 13 hours with 67% remaining. Thats pretty good. But if you look at my awake and up time youll see ive only have 8 hours awake, with 48 hours of up time. What this means ( for those that dont know ) is my phone hasnt bern rebooted for 48 hours (up time), in those 48 hours, my screen has been on ( ive been doing something on the phone) for 8 hours (awake time). Now on this charge im showing you. I probably only have about 2-3 of those awake hours . As you can see I.bareley used the phone. 40% on call standby u know. Im running netarchy 4.2.1 CFS HAVS More Aggresive Smartass. Which is an awesome kernel. Phone is faster than ever and battery does not drain much while sitting in my pocket. Now what I want is a kernel that will give me 6-7 hours of awake time in one charge period with around fifty percent battery left. Am I dreaming ?? Oh yeah and phone doesnt have to be superfast, just be workable ( basically not frustrating). Any suggestions??

That's about my average. I don't think realistically we can get better than that. I use my phone a good bit. I'm a photojournalist so I'm using the camera/calls/email quite a bit during a normal day. If you make it through a normal day, you are fine. Why fix something that's not broken? Actually, while typing this I realized you said you had 60% left. That's actually a lot better than me. Discribe your usage for me. I can only get about 4 hours of awake time with about 15-16 up before the phone is dead. You however would get about 6 or 7. Jealous.

Your rite on with my average. I said I had about 2 hours of awake time in one charge with 13 hours since tooken of the charger with 60% left. So yeah in 4 hours of awake I would probably be almost dead too.

Yes, that is the right one.
In your first screen shot he is just showing you all the change logs.

^ Thank you, I appreciate it.
Well today I flashed the Kernel and I think I have another issue which is causing Major battery drain.
On the Charger at 1:30
And again at 4:30
I bump-charged this morning too.
Here's what Android System had been running
And finally
What's up with my battery usage? I even have a 1500mAh Evo that doesn't seem to help.
Maybe it's my rom?

I was having a similiar issue as you ,running Business sense Z rom I installed Lou's number 8, I wiped Dalvik and cache and battery stats now the battery doesn't drain as fast. Previous to doing this I was only getting about 8 hrs on a full charge. Also my dislpay was around 70% is down to around 40%

34 minutes later peep the battery level

What is your brightness set to? I'm lead to believe high brightness is the number one cause for poor battery life. In general, your screen is the number one draw from your battery. By the one screenshot of battery usage, I might be on to something
edit: turn off the gps too if you havent.

I wound up flashing a recovery of Incredibly re-ingineered.
Check out the data used:
I found a temporary fix.
Today I burned through 4 batteries
Totaling 5400 mAh (1-1500 evo & 3-1300 eris/incredible batteries).
So yeah, lame.

Maybe try out a AOSP rom, sense roms sync too much, too often. Then start tweaking usage + other stuff.
Consider downloading setcpu here on xda. Set main to run at 600 MHz max, min at 128. Set to conservative and hit set on boot. Make 2 more profiles, a temp and a screen off to have the same values: 384 max, 128 min. Temp should kick in at around 40C. Then go to advanced, change up to 75, down to 25 and freq step to 10. If you want to go a little more crazy, cap it all off with juice defender free.
If you do go AOSP, get chad's latest then flash the aggressive HAVS settings. If you do do this, you might want to then go into setcpu -> info and run a stress test just to see if it is stable.

Thank you Sir/all, I'll look into that.
This is good info for myself & others.

Try a different kernel. I tried Ziggy's and battery charge pretty much evaporated. Switched to Lou's #9 and it's been smooth sailing ever since.

Rom with best battery life

As per title, which roms has gives the desire the best battery life? I presume it will be AOSP roms like redux?

Oxygen wins by me.

TouchPaled from Oxygen with Transparent XDA App

I used the HTC Gingerbread rom and flashed it to Gingervillian and didn't really notice a difference.

I love my MIUI =)

Oxygen. Can get up to 3 days battery without touching it. I'd say it's thanks to Thalamus' kernel though.

the problem is that we need to touch the phone..haha lol
to the OP: the battery life ONLY depends on how u use the phone. every rom is about same..no magic things anywhere

Oxygen or MIUI...
But as far as i know, it also depends on what kernel and/or radio you are using

And I think that Oxygen is the best battery saver.

Haven't tried Oxygen but Redux is pretty good.

What was 26 hours with SGBS ended up being 51hrs on Oxygen. Same widget setup, both times the device was used with screen on time of 2h30m and roughly the same talk time. I was at the same place both time and the radio was the same, this one in my sig.

How much "Screen on" time do you people get?
I can easily get 3 days if I don't use my phone at all, but that kind of defeats the purpose of a smartphone.
The max display on time I can get is between 4-5 hours.
But that is if I use it for reading a pdf-book in night mode (black background with grey text)
If I browse the interwebs I get max 2½ hours because of the mostly white background.
Playing games (Angry Birds) is 1½-2 hours.
What do all of you get?

For me Oxygen is the best ROM for battery performance.

Screen on time nearly five hours (checking facebook and twitter, email, some chat and xda forum app; brightness: 20 - 25 %) with some phone calls drains my battery from 100% to 10% with ~ 1d 11h on it. At the moment I do not play any games.
CPU-Setting: Min 245, Max 768 ONDEMAND governor. I do not use setcpu or juice defender or anything like this. Just the cpu controller included in oxygen. Could not notice any difference so far. Thalamus' kernels seems to be very well programmed.

Oxygen or Solstice

Cheers guys, oxygen Rom it is then.
With the oxygen Rom, which is the most battery efficient kernel?

has anyone experience with a sense rom?

Huge battery drain, 122Mhz cpu state unused

I've been suffering massive battery drain on my phone since trying out a different region stock(xxml8) and flashing CM9 over it. Even after a complete wipe and restoring my old stock XXKL3, the drain is the same. I get 10hrs at best. Cpuspy tells me my 122Mhz state is unused, so after deep sleep the next state is 245mhz. I never used cpuspy before my battery problems so I don't know if this is normal on stock rom. Or could playing with the governors on CM9 break something with my cpu and causing huge drain? I think if the 122Mhz was available to be used I would use less battery. Any ideas guys?

-On the frequency i've been always using 122mhz--1401mhz because it saves power on lock screen and makes my battery last longer.
-you are not supposed to use 122mhz because you cannot listen to music at 122mhz because it stutters and laggs. thats why default is 245mhz.
-If samsung made the slowest speed 122mhz everybody will be complaining on music.245mhz can play music with no lagg and stuttering.
..............on demand 122mhz to 1401mhz is the best for me.................

Using Antutu Cpu Master I've been able to set the minimum frequency to 122Mhz. Will check if helps. However, my battery consumption with screen on is still huge. Don't know how I can fix this. I could get close to 6hrs continuous screen-on time before.

WOW my phone is amazing is nearly get 8hours(7h 53m) of continually using my phone through-out the day.
When im power saving it get 11hours with still 41percent left.

I've noticed recently that my battery is bloated. This can only mean it's physically degraded that's why I've lost so much battery life. This only happened after I flashed CM9. Before then I had a day of battery easily. There was a lot of overheating with CM9 maybe that was the reason.
Sent from my Wonder

yeah after I flashed a ROM my battery life was bad and my phone Battery got dangerously hot 50+.
so now I am on stock because my phone runs very cool and has much longer Battery life.
