Currently using Docs 7.2 JPO rom and its running fine except for battery life. Basically heres the problem, I can either use the EXT4 lagfix and suffer poor battery life or use RFS, get excellent battery life but poor performance. What are my options?
I'm using doc's jpa 7.6, it's fast and battery life looks good enough for me. currently at 1d 20h, 30% remaining. Using norfs advanced ext4 lagfix.
Did you try doing the factory reset etc? I've had battery problems before caused by some app hiding in the background and draining battery, without even running..

You just answered your question..
but anyway, more performance = higher battery drain..

I heard it has something to do with the ext4 filesystem. Apparently ext2 gets better battery...

Its definitely the lagfix and many other users are experiencing the same problem.
With doc's v8 and a 1.2Ghz kernel its running pretty fast w/o EXT4, in my experience its running faster and smoother.

Fellows, i just bought my SGS a few days ago , and the moment i bought it i upgraded it to Arabic stock froyo and a friend recommended to use stock+Voodoo-5.0.3-Froyo-GT-I9000-XXJPX kernel
i used it , got 1424 on quadrant and it was very nice in performance but i got strange battery life, it didn't last for more than 10 hours with everything switched off.
so i returned back to stock froyo (pda I9000 jpjpf, phone I9000 jxjpd) and now i got nearly 24 hours of battery life.
what confuses me is that, during using voodoo, the battery was during the first 2 charging cycles of its life, and when i returned to stock froyo , it got into the 3rd charging cycle, and now its moving on towards getting better in battery life.
so my question is , do you think that the kernel was responsible for this strange battery life, or the battery was warming up and needed to be charged and discharged to get into its performance.
also , any suggestions about kernel for battery life with good performance, personally i did like the phone when it was on voodoo @ 1424 on quadrant
please help , and sorry for explaining a lot
thanks
Quadrant is a false test when it comes to use and responsive phone .

thanks for your reply
i did like the phone when it was on vodoo, regardless of quadrent
my aim is to know about battery life

Read the battery faqs and posts on this very page .
But battery life is very very variable .
jje
i am afraid that battery faq does not have an answer to my question
i want to know if the change in kernel is responsible for that strange battery condition
or it was that the battery was at its first charge and discharge cycle?
Going from 10 to 24h of battery life, it could be a battery stats problem, it happens when changing ROMs.
But to answer your question, I dont think voodoo is responsible for the battery drain. Personally I use SpeedMod (without lagfix) with Froyo JS3 and it works really well battery-wise and performance-wise.
you don't think that voodoo is responsible ,
well that's some good news for me actually cuz i did like my phone's performance when it was using voodoo's kernel
thanks for sugesting speedmod , will read about it for sometime and see if i dare to take this action again , cuz battery life is a must for me due to my work
i can't stand the phone that needs more than one charge per day
any more ideas everyone?
I also use speedmod and battery life is excellent. Even with heavy use I get over 24 hours no problem. If I was to use it just as a phone I think I could get 3 days use.
And yes, I agree that your battery stats were probably a little messed up and should settle after a few days of use.

I'm using SpeedMod with SeaARMS' JL2 ROM and the battery lasts much longer. If you have a Galaxy S on Bell Mobility it's the best option to keep the 850Mhz radio working.
hmm. to the best of u guys knowledge, can i hear from u guy which combinations (roms, kernel, modem) is the best for batt life?
i had tried the wiping of batt stats, but the result is almost the same. my galaxy s can hardly last for a day with normal usage (facebook, few mins of games, texts)
kinda disappointed the batt life of galaxy s. lol
Overall Darky rom tend to have low battery life, drain, etc. I tried first with Hardcore's kernel, then Voodoo, which was even worse. The idle drain was not that bad, but when I used the phone... 2min/1%!!! That was mad.
So I put back the old and reliable doc rom with speedmod, and although it's not that smooth, the battery life is pretty powerful!
(no lagfix)
would be kinda easier if you did a POLL here which kernel to use for good battery life.
I am on stock JPY 2.2.1 + speedmod and my SGS battery almost doubled.
Ive heard the Damian's kernel with undervolting is very good for battery life
ok polls are up.
Do let me know if i missed out any good roms / kernels combinations, as I gathered them based on popularity.
and also if possible, share yur opinion on the performance of the roms / kernels that u are using. thks =D
more polls pls!
It all depends upon the way you use it. I prefer Stock Kernel for battery life.
Jve gingerbread modem has made the biggest improvement in battery life for me
Stock JPY, Insanity SpeedMod OC-1200Mhz/UV, ext4, JVE gingerbread Modem,
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?

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?

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

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!

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)
Which 2.2 ROM for the Milestone is the fastest, but also has great battery life? One that will withstand running apps smoothly, but not killing the battery so quickly.
any rom 2.2 to 550-800mhz overclocking increases battery life 2 days straight ... I recommend Rom rentail brazil .. Froyo 2.2
http://forum.xda-developers.com/showthread.php?t=1007493&highlight=brazil this one?
yeah .. but I do not have the link to the ROM
In my opinion TheFroyoMOD is the best one.
CM6 is the best Froyo-based ROM, however CM7 provides better battery life and performance, compared to Froyo.

You can get either fastest or great battery life, not both... Stock Froyo is better in the battery life department than anything else, some roms are close, but even with undervolt and turning off radios/3G when not needed, stock froyo battery life is better (and can get even better by doing the exact same thing)...
Altough, it is not as smooth as Froyomod or CM6 or CM7....
You will have to either give up a little bit of battery life, or a lot of smoothnes.... My Milestone is running CM7 and I think that it is, overall, the best option for it.

Moved to Q&A
Hi,
Whether I'm on the latest SlimBean, CM10 or CM9, battery life is always bad for me. I don't have draining apps and when the phone is idle it's not using battery at all. The problem lies within usage, when I'm using my phone, the battery life goes down too fast (when I'm using Whatsapp and Gmail. Especially when you compare it to stock.
I've done a bit of reading and many people suggest the Modem and Kernel files can have a huge impact on battery life.
So, I wonder, what would you guys recommend to increase my battery life during usage?
I've found this thread with modems: http://forum.xda-developers.com/showthread.php?t=1870460
(My wish is a fast phone with a ROM that looks nice, like the latest SlimBean, but I appreciate battery life more. However, a rooted Gingerbread stock ROM goes so slow...)
