Hey guys coming from the evo forums with a question for you all. My buddy has a Droid which I rooted for him yesterday and I was looking for some kernels for him. Do any exist?
There's a bunch in rom manager he can try. Personally I tried a handful and never noticed an improvement that was worth my phone seeming hotter and battery life decreasing even a little (I'm on my phone alot). I've had the best results just using setcpu and over/underclocking the stock cyanogen kernel.

Thanks for the reply. Yeah, cyanogen was the first thing I flashed for him. haha
Thanks again.
What Rom is he running?
I know of no compatible Cyanogenmod 6.0.0 kernels in the Rom Manager, but I could be wrong.
Kernels are pointless, all they do is eat your battery.
I have to disagree. I've been using OC kernels since first rooting my phone. I personally see a pretty sizeable difference between running 600mhz and 1000 or 1200mhz. There are many kernels out there that run at 1000 on less than the stock voltage. As for the battery life I really haven't noticed a difference. I gan get a full 10 hrs of moderate to heavy use out of my phone before I hit 20% battery. Cruise on over to droidforums.net if you like. They will have everything that you need to set your buddy up

What is the sleekest rom that is farely fast in quadrant yet the battery life (combined with a modem and kernel) is dependable for light to medium use? Im currently on pheonix ultimate. Not only is it fairly slow but the battery life is not the best even when screen is off and wiring and data are off.
Sorry if it has been asked before. I prefer a gingerbread based captivate rom but anything 2.2 or over is suffice. Maybe explain too what a good modem and kernel are that don't necessarily oc or uv but can...that don't drain battery!
Much Appreciated,
Your Noob.

Haha... Wait for it...
Not sure what the answer to your question is, but this hardly belongs in the Dev section. Q&A would probably be best. I have already sent request for this to be moved. Oh well... hope you get an answer after it's in the right section.

Quadrant means nothing. Dude

It's hard to say which ROM is the *best*, you just have to give them all a shot and see which works best for yourself. Battery wise, doesn't only depend on the ROM itself but also if your battery is old, you might consider changing it.
I don't think quadrant matter either, just numbers, as long as the phone is smooth when I use it, it's fine with me.
Quadrant doesn't mean a thing, but I have found that kh3 roms have the best battery life.
Currently Pinnacle 1.2 and have never been happier
fusion v is fenomenal. fasty is great too, if you can deal with the obtrusive theme and animations
Why don't you just try flashing some roms and see what best suits you instead of asking a community to publicity place a value judgement on other developers hard work?
And for your edification, this is the type of question for.... you guessed it.... q&a, not development.

No rom is the best. But my experience Native roms tend to run smoother for longer periods of time, and 2.3.4 KH3 roms have the best battery life. Dont ask for "best" because there is no best you gain some things and loose other. So try them out.
I'm not talking about the charging issue but mainly the battery drainage. What is your average battery life with i9000 roms? I love them cause there are so many features included with them and they're smoooooth but I feel as if the battery drain is way too fast. 10% in one hour of minimal-average usage.
Is this common?
I have only used one I9000 rom, Mosaic VII and I love it but yes the battery life is less than I had on Fusion VI or Fasty II but my phone runs so much smoother. I'm going to run it for awhile and see if the battery life improves.

Alright cool. Let me know how the batterye is for you because for me there wasn't enough battery to last a day
I'm going back to Froyo roms for awhile. I was bragging to my wife how fast Mosaic 7 was and her phone was just as fast running Cognition Froyo rom. She has a Captivate also. Her's had much better gps and battery life. Post a note if you find a good GB rom. I'm running Serendipity 6.4 right now. So far pretty quick. Strong gps.

Hello all,
I have seen reports that because the source code for the captivate has not been fully released, some of the processes cannot be put to sleep when they are not being used, and therefore causes bad battery life. I am just about to flash CM 7.1 and am curious to know how the battery life is on the captivate.
All info is greatly appreciated!
LWt mw know what you find out! Just flashed it and my battery goes quicker than my bank account. Please let me know what I can do to help this I like the rom

Jaye,
This happens frequently when flashing a new ROM, you should try wiping the battery stats or giving the ROM a few days to calibrate with the battery.
Been a week for me and battery life is still horrible. I lose about 25% an hour

You should try a custom kernel like glitch or Neo to see if that will help. I get awesome battery life in miui which is bases of cm7. I find that neo gives me the best battery life.

What do you think about the Boog Kernel?
http://forum.xda-developers.com/showthread.php?t=1294849
Also, some people must be getting solid battery life, or CM7 wouldn't be as popular as it is. Or is this a known thing with CM7?

I get better battery life on miui and neo kernel than any samsung rom I have tried. But each phone is different.

Yeah that's pretty awful. Try doing a battery calibration to see if that helps. It should never go that quick (unless you're playing some serious games). I've never really had great battery life with cm7/miui I've had the best battery life with all the recent samsung gingerbread leaks. I think those are better than cm7. But that's my opinion.
I am in CM7.1 since Sunday. I had very awful battery in start. So I did battery calibration, manually. So I got very decent battery on wifi. But at work I use att data so again my battery life was horrible. But I am seeing improvement since I am using this app called green power to manage my data. Try that.

If you get good battery on WiFi but not with mobile data, try a different modem. Not only are some modems inherently better on battery, but if you find one that gives you a better signal you should see improvements in battery life as well.
Flashing the Glitch kernel seems to have improved my battery life.

Hi, Can you point me to a post that (a) has the Neo Kernel and (b) explains how to flash it on MIUI? I've had MIUI for a couple of months now and battery is to as good as expected. Would love to try to use another Kernel but I sincerely don't know how to do it.
Thanks in advance,
Mauricio
I just love MIUI, no battery problems for me. Gets me through 2 days of moderate usage so I'm a happy camper.
I just wish it had the Audience chip workingg...

Solid Battery Life w/ Stock Kernel
Hey Everyone,
Juts came to report that I have been getting great battery life using the stock kernel. I would say it is a little better than Serendipty VII Build 2 which I came from. Only issue, and this is something I know is inherently wrong with Cyanogenmod on the Captivate, when you fully charge the device, it only shows it is charged to 98%.
Other than that, all good!

Not true, you need to calibrate your batter!!!!
I get awesome battery using wifi all day long, with auto brightness, music and videos often.

Oooohhhhh, sweet! I thought this was a common issue. I remember it was during the nightlies.
I am using the following application:

I will report back!

Have you seen an improvement in this regards, I am having the same issues, the WiFi is draining my battery slower then my data is.
I have also done the battery calibration and it doesn't seem AS bad... still doesn't appear to be great though.
I am just coming back to this ROM after experiencing battery issues even though Glitch helped a little. I decided to try and tweak some more this go round.
I am experiencing much better results this time. Here are settings and other tweaks or modifications I have in place.
-sync is turned off
-using Launcher Pro with very few widgets (just 3GWatchdog and Power Control)
-auto brightness turn off manually adjust according to need
-gps, wifi, BT, and data turned off when not in use
-wifi notification and location detect off
-installed jk4 modem (may get better results with different modem depending on your area)
-installed Glitch v12 high leakage
-the biggest factor this time I think is UVing on the Freqs that are used while phone sleeps >>>>>100/200mhz (set for the lowest UV setting possible on these that do not result in a sleep death or reboot when phone is put to sleep)
Hello, I am currently using MIUI but it sucks for battery life. I want to flash a stable rom with long battery life, and nevr to forget about flashing (because I will sell my phone to a friend of mine very soon and he is noob in all of this things like roms). What would you recommend?
Sent from my I897 using XDA App
I had amazing battery life with Pinnacle. 24+ hr easily with medium-heavy usage (very subjective, but 100x better than MIUI, CM7)
I flashed serendipity 6.4 on my mother in laws phone in july and I have yet to have to do anything with it except the things she messes up, like losing the app drawer icon. I also ran the rom on my phone and it had great battery life.

Generally speaking native roms offer the best battery life over all (KH3, KI#, KJ#,KK#, etc). But like mentioned before very subjective. This thread will probably be closed due to the nature of it.
If you are giving it to a friend that is not into roms. Stock is your best bet. Don't want them to have to deal with the issues of a custom rom. Like drivers and app compatibility issues in AOSP roms like CM and roms like MIUI.
