Hey, im currently running trigger 3.3 and loving it. But i just wanted to ask you guys about your favorite kernels that give some of the best battery life.
im using bali 1.8.8uv and its still in the calibration phase but i feel like it gives some pretty good battery life.
What are your thoughts on the best battery life kernel that has a decent performance as well?
I'm on BaliUV also, fully calibrated, and I got 14 hours with 36% left before I went home. Somewhat light use. Pretty good if you ask me
Call me crazy but I think some phones just play nice with a certain kernel and others don't. Some can over clock / UV and others cant.
It seems silly but I tend to return to the old Overstock kernel. It just plays REAL nice with my phone.
I use Bali-X 1.2... Not for the overclocking ability (which my pathetic phone can't handle), but so I can undervolt even farther than the Bali UV kernel. I keep my phone undervolted by 100, and it is rock solid with this kernel and has awesometastic battery life.
I was always a big fan of CwK

What is the best vibrant rom for battery life? This is going to be for my g/f I am running MIUI on my evo and was happy to see the vibrant starting to get a taste of that greatness
Anyone have a recommendation for best battery life? I have flashed team whiskey's bionix but it's draining the battery like crazy, battery is dead in literally 6-8 hour with little use, no apps installed, nothing......
as batttery-wise..
Master's Axura has always done the trick for me.
But the key is to recondition your battery.
Recondition it on every rom you go and you will definately last 15+ hours easily with light-moderate use
Stock, bionix v, nero 5... either of these will do. If you want to see some great extended battery life I would suggest to dl the "superpower" and "setcpu" apps. If you tweak these two Apps they can make a big difference.
Most I got out of nero5 as 32+ hours.
Gotta say, the Axura really has the best battery of all the roms I have used and I have used them all, but remember your specific usage habits affect the battery life results.....
Axura has been great for me. I've been on axura, bionix, and nero v5 and axura is by far the best.

I've tried just about every rom out there at this point and they all get decent battery life for me. It's when I start using OC kernels that I start seeing alot of battery drain but even those are getting better.
So i have a filename. I love minuit and all the features/customization, but the battery life is killing me BC i work long hours outside. So my question is, shud i just deal or downgrade back to my wonderful battery life from Froyo?

Looking at my previous ROMs on my Vibrant, I have resorted back to Battery Life. Yes, the extra tweaks and pretty customization are very eye candy but in the long run, you want a phone to be a phone that can last you whenever you need it when you go out for a long night or for a mini trip. I feel it's pointless for a pretty arse phone that can only last you a few hours. It's only good for the show. For me, I found a middle ground of battery life and customizables with Toxic8.
From the past, my best battery life comes out from Bi-Winning, then Bionix, then Toxic8, and then the GingerBread ROMs and then CM7.
Kudos to Toxic 8. It looks amazing and it has a good battery life!
You can also try Trigger3.2. I tried it and personally have found it to have better battery life than Bionix. However it's all preference.
Try Trigger3.2/Toxic8/Bionix with bali and see which one works for you!
I've tried them all and Biwinning and Bionix give you the best life and stability (along with a Bali or Immortality kernel)
Toxic8 also rocks with its themes (geared towards young people) but at it's current latest state, the GPS warms up the battery and kills the battery life.
The rest of the ROMS you have to play with and see what you like. The battery life is most important to me and the ROMS mentioned above are fast and stable. I don't need more until an official GB leak is released for the Vibrant.
when battery life is the main preference, which ROM should I chose?
I am using CM7 for the last 3 weeks and it's been horrible compared to stock.
Thanks!!!
I like the team toxic rc3 D9 has a good battery life and very smooth
why not taste a little ics passion v11
18 to 21 hours of batt. I'm lovin this rom!!!
check it out....
D9 has one of the best, but of course is based off of 2.2. Also, hasn't been updated in a while.
ICS Passion is by far the best ROM for the Vibrant at the moment. No lag, everything works, and the battery life is amazing. I recommend it. Have been using it since v5 and the improvementsare great and good to see.

I am not so sure bout this one. I just flashed my phone to ICS passion V11 and it only lasts half a day with wifi on, gps off, sync off... or maybe it is just me.
I've tried a dozen ROMs over the past year and they've all been about the same until recently. The Passion ICS ROM has had the best battery life that I've ever had on the Vibrant. The only thing that drains it is the pulse notification light. It's a great feature and I love it, but it drains the battery quick and it tends to come back on every time you reboot the phone. I ODINed from LIDROID to Passion ICS.
I will have to concur with the other few. The Passion ICS so far seems to cut the cake... also with appearance.
If you havent already you could consider Trigger 3.3. I cant speak on others.
Battery life was pretty reasonable on there with full-day wifi usage, net searching, multiple app usage, some music listening and customizing, and often some bluetooth...lets not forget brightness mid to high.
But you may have to also consider the amount of cycles your battery has been using. Maybe you can come out better with a replacement IF its feeling like its not performing at it peak potential.

Ics passion is horrible battery life for me
...and here we go again.
I've been using ICS Passion v11 for a few days, and I've consistenntly getting 30+ hours of battery, and Wi-fi is always on, screen brightness about half maximum.
I have been using DOC's Master ICS ROM V2 and have been getting 12 - 15 hours with heavy use while connected to a bluetooth headset. I have 1 glitch though, I can not send pictures through the stock text messaging app. I used Passion beta v5 and had extremely horrible battery. I read that all the battery drains have been fixed. I am going to give Passion v12 a try. hopefully i can send pictures from text on there!
zendroid 2.1.2 with bali UV kernel
I couldnt believe it, but my girlfriends vibrant showed 3 days and 14 hours on battery since plugging it in last time with still 8% battery left. Thats absolutly insane on a standard 1500 battery. Personally i dont care that much about heavy use but rather standby time. thats always been best with bali 1.8.8 uv kernel and zendroid combination (probably bionix is good too - in general 2.2 roms seem to be much better in this regard)
im running bionix 1.3.1 pair with bali kernel 1.8.8 no uv no oc. so far so good. i can run it for ALMOST 2 days. moderate to heavy usage.
If your looking for speed/stability and extremely good battery life you should go with Fisherman's V3 Bionix 1.3.1 with the bali kernel. That rom is the ish make sure after you flash the rom you use the battery calibrator from the market and calibrate your battery and your open for buisness
So I took the plunge and unlocked my bootloader, and flashed the latest weekly of CM7. I love it so far, very responsive and quick.
I decided to flash the latest Faux123 kernel (CM7 Unified). After getting great quadrant scores, I was happy. I have a custom kernel on my Transformer TF-101 as well.
Here's my issue:
I get about 3 hours of battery life.
I clocked the kernel to max at 1.2ghz, and I even scaled the governor to powersave. (Using Rom Toolbox, min/max in SetCPU).
I have not undervolted anything at all.
My phone idle seems to shoot up to 40-50% most of the time, and SetCPU says that my phone spends most of it's time at 1ghz+. My TF would pretty much fall asleep at 216mhz, but that's a different device.
Is there something I'm missing?
This was a clean flash, and I always have plenty of free ram. I don't seem to have any wakelocks longer than 10 mins (alarm manager) either.
Oh, and my battery has been properly calibrated.
The stock kernel gave me great life (30+ hours). I expected a little loss, but not this bad after flashing.
Help!
Try a newer kernel. Governors don't work properly with our tegras. A newer kernel should have that disabled and more power save options.

What kernel do you suggest? Ive been out of the atrix scene for a good bit now lol.
My issues with battery life disappeared after installing jokersax's cm9 beta along with faux's kernel for cm9
Also be sure your battery isnt old and calibrate it(guides on main atrix forum)
Can I use a cm9 kernel on cm7? I don't really want to take the ICS route until it's developed a bit more.
My battery has been properly calibrated, though it still doesn't always hit 100%. I have no idea why either.

I woldnt try that.. About cm9, even though its beta, its pretty usable right now, most stuff works fine, you can always go back id it doesnt work.. I didnt went back bcuz battery is most important for me
Hmm, what about kholk or clemsyn's kernels?

I've stuck with fauxs. I think I'm using version 23. I'm not using the lastest one as it makes one of my apps buggy and I don't like how my CPU jumps around when idle. He is currently working on those bugs, but they are hard to correct. Lots of other people are using it though with good results. I also stay with the 1.0ghz versions. Overclocks are nice but I don't need them and perfer the extra battery life.

So after a night's recharge, it seems to be working a little better.
CPU Spy says that it's in deep sleep most of the time.
Turns out I had SetCPU, Rom Toolbox, and CM7's settings regulating the clock speed. I uninstalled SetCPU, turned off Rom Toolbox, and let CM7 take care of it.
Life isn't as great as I expected, but its an improvement. The processor still does "jump around", but I expect that to be fixed at some point.
I considered clemsyn's kernel, but I don't want to risk not having an "elite tegra" and blow up my phone.
I really like the .24 1.3ghz Faux kernel. With SetCpu I change between 1.2OC (using lapdock) and 1.1OC (rest of time).
Battery life is equivalent to stock kernel. (I put it on charge when I go to bed and take it off early in the am). It usually has 50% left after streaming music to and from work/Endomondo using gps to track 45 minute workout, all my widgets (news and weather) and a few phone calls.
Phone stays much cooler.
Quadrant standard vs my wife's Atrix (fully stock) with the kernel at 1.1 is 30% better.
Stock ROM; not CM7 however.
I just looked at a days logs. It says that my phone spends 3+ hours in both 1.2ghz and 800mhz, and about 9 hours in deep sleep.
I haven't used my phone much today (40m of display time), and it already got to 15% between 9am and 6pm.
I can't seem to find what's keeping it up either, no obscene wakelocks.
I have been using MeanRom and MikVirgin off and on. I like MikVirgin alot better, and want to use it full time, but the battery life is terrible. MeanRom makes my battery last at least twice as long, but I get worse reception. I read somewhere that the great battery life has something to do with turning off one of the cores while the screen is off. I'm not an expert, but i think that is a kernel issue.
Is there a kernel that I can use with MikVirgin that will give me battery life similar to MeanRom?
That's a relatively hard question to say which kernel gives good battery life. Because no one kernel by itself can save more battery life than the other. Some do handle the tasks and compliment the CPU better than others. It all boils down to how your kernel is set up, what governor you use when your screen is on. What frequencies on and off, overclocking the CPU drains battery quickly. Having both cores online and one off when screen off. What I/o scheduler in combimation with a governor. It really depends on how you use or phone to best suit your needs, not one combination is best. While maintaining good battery is a must sometimes you end up sacrificing from performance and your phone suffers with lags. From these experiences I have found that the cool kernel and the forbidden kernel give good balance and stability in most sense roms. Along with meanrom and common sense. Those two roms I have found to give good bettery life. You just got to experiment. While one combimation of Rom, and kernel work for one persons EVO may not be the same on another persons.
