[Q] Kernel with best battery life

Hey guys, I recently flash cm rc1 and been running whatever kernel that came with it. My battery life has been worse compared to stock froyo 2.2. I'm a medium usage person so I was wondering what kernel is best for battery life and what setting are people running for setcpu to maximize they battery life. Thanks in advnace.

Great question. I would like to know this too.

It seems no matter what the kernel and no matter what the Tom, everyone has different outcomes on battery life... try some out and see what works for you..

Yes, it is amazing the difference in opinion on this subject. I easily get 16 hours of battery life with moderate to heavy usage, and 1.5 days with light usage. And I am using plain CM7 RC1, without any CPU/Battery apps. Trinity or Faux kernels reduce this considerably regardless of the OC/UV combos I have tried.
To make sure you are getting accurate results and to get best battery life make sure you calibrate the battery (there is an app for this, or can be done manually). This has proven to solve problems I've had where I only get about 8 hours battery life after changing Roms.

Faux's is the only custom kernel I've tried, and my battery life is unbelievable. It's almost doubled.

Setcpu for infused

Do any of you guys use it on your infused? I have it and would like to use it but I've read a few things were setcpu doesn't doing anything with a custom rom. Id like to get all I can out of my battery.

Most of us who are using infusion (available in the dev section) are using voltage control, pretty much the same thing in a different app but it seems to play nicer with said kernel

I'm using SetCPU with the Infusion kernel as it's the first app I paid for, and I feel weird about switching apps right after I paid for one.
Man it's so confusing to have the Infused ROM and Infusion kernel.

What's the difference between infused and infusion? I'm going to a redsox game next week via bus trip and really need to maximize battery.

For using Voltage Control u need to update the kernel. The default supplied one does not allow to use the Voltage Control app available in market (tried just now to make sure).

Infused is a ROM and Infusion is a kernel. Both can be found in the Infuse 4G development page. I've noticed a battery increase with Infused, just make sure you do it a day or two before you leave to get the most out of your battery. Details are in the forum.

Infused is an alternative ROM which eliminates a lot of AT&T bloat. Some of the things it eliminates are notorious battery hogs. It contains a kernel with mild improvements from stock.
Infusion is an alternate kernel that introduces extra improvements from the Community Voodoo kernel included with Infused, including undervolting and overclocking. Undervolting can improve your battery life at the risk of stability impacts if you UV too much, OC will sacrifice battery for the sake of performance.
You can install the Infusion kernel over the Infused ROM.
Note: If you are in an area with weak cell signal, your battery life is going to be crud no matter what you do unless you go into airplane mode.

Thanks for the great reply. I'm at work over 9hrs per day and when I'm in the actual building my phone bounces between 1 bar edge, 1 bar 3g and no service. If I keep the phone still on my desk it'll be all set but once I start walking around here comes no service.
Is the kernal werth installing? I know its a junk question. And can someone link or pm me the instructions. Thanks.

Are you rooted and have 3e recovery? If not, just jump over to the development section and read the root instructions and 3e instructions.
There is a great guide in the thread for the Infused ROM on how to go from rooted+3e -> custom rom, in the original post.

Hey guys...just a reminder....setcpu is free for xda members
http://forum.xda-developers.com/showthread.php?t=505419
by all means support the dev....but for those who did not know.
I use it....mainly for overclocking though. Have not really messed with undervolting yet

Yes I'm rooted and I've been running infused rom for a few weeks now. I just really need to maximize my battery. My phone has been off the charger from a full charge for less than an hour and I'm down to 87%, btw I've used my phone for about 15 of the total 60 minutes it's been off the charger.

Really, time to empty is what you need to pay attention to. Our fuel gauge seems to be a bit wacky, sometimes it can drop 10% in an hour, then it'll drop 10% over the following 4 under the same workload. I think the drain isn't actually changing, just the display of state of charge.
As an example, at one point yesterday I dropped 10% in an hour with the screen off for nearly all of it. Then I threw it on the charger and regained 9% in 20 minutes - even with my tweaked charge current it NEVER does that. I think what happened is that the original 10% drop was bogus, I got it back so fast because it was never really gone to begin with.

[Q] Infused 1.5.3 battery life?

I am running Infused 1.5.3 right now and was wondering if I would get better battery life running a custom kernel like Defused, Infusion Kernel 1.8, or Bionix. I just flashed my phone and am new to the Android and Infuse community. I am coming from a iPhone. Your opinions would be helpful. I am trying to figure out why my battery life kinda sucks right now and I am looking into a custom kernel. Which kernel you guys using?

If you install Infusion 1.8 and undervolt without overclocking, it will improve things somewhat.
If it's still bad, uninstall all apps, then install them one by one until you figure out which one is hosing your battery life.

The kernal that came with the infused is working just fine with me. The defuse gave me horrible battery life. But yeah, take entropy advice.

The only time my battery sucked was when I had a rogue app updating **** all the time. And when under volting was broken lol

I use setcpu. I created a profile for "screen off" and turned everything down, seems to make my phone last longer.

Help with Roms, Karnels, Etc..

ok so i got my charge 2 days ago and am rooted with Gingerbread leak,
so i have some questions.
First: is there roms for gingerbread? because i couldn't find any.
Second: what kernels are there for GB? can i use PBJ?
Third: now ever since i got the phone it drains batter pretty quick with everything off. and hardly using it maybe about 20% per hour. i tried undervolting with Setcpu but wasn't successful, so what app do you guys recommend to undervolt the charge? or any guides to do so?
thanks,

Check out the development section. Gummy Charged GBE is great

I did, thanks for the reply. now i have voodoo and on the recovery sais enable 100mhv something like that. is that so i would get more battery?

You can't undervolt on gb because its a leak meaning no kernel source.
I think setcpu will let you underclock which would give better battery life but reduce performance considerably.

Whenever you change roms, you should calibrate your battery. It works wonders

You need to return to stock, then fresh Odin GummyCharged GBE 1.9RC2.3 if you want Gingerbread as it's really the only modified Gingerbread rom. Eclipse is available, but i'm not sure if the dev still supports it or not. The quick battery drain is something that goes along with the fact Gingerbread is a leak. GummyCharged team has done a wonderful job with minimizing this drain. I have found it actually has better battery life than Froyo. That's just my personal experience.

Best ROM for battery life..

Nexus s 4g what is the best set up for battery life? Currently running matrix cfq with ondemand gov @ 800mhz .. And its like its not going to sleep.. losing 15% every 2 hours with screen and data off

Try to wipe battery stats at 100% and get through at least two charge cycles, it helped in my case

personally , stock ROM has longest battery life

I´m running MV Nexus Rom with matrix 10.5... Using 1320/440... Deep idle enabled and max freq when screen off enabled and it´s giving an awesome battery life... I´m using a TMo Nexus S

Honestly I'm not sure what deep idle is.. I'm working on a friends phone.. I have a charge. I didn't know smartass was an option.. But I'll def hit that up.. So how do I enable deep idle? And how would raising min clock speed save battery life? jw?

Bionix 1.5 with Morfics TEUV, best battery life for sure!

try oxgyen...
super simple ROM....

Bionix seems amazing for battery life as well.
