[q] which kernel is better for battery life? - Galaxy S I9000 Q&A, Help & Troubleshooting

HI GUYS!
I NEED HELP!!!!!!
WHICH KERNEL IS BETTER FOR BATTERY LIFE FOR MY GALAXY S GT-I9000 RUNNING CM9 ICS 4.0.4 NIGHTLY
I'M ON SEMAPHORE 1.2.2S.
IS DEVIL V3 BETTER THAN SEMAPHORE 1.2.2S?
CAN YOU SUGGEST FOR ME A GOOD KERNEL FOR BATTERY LIFE ??!!

Depends how you set them up......but please don't shout, I have a hangover

Try them and test them! The suggestion to keep the same settings for each of them! And make your own, comparisons. Good luck

I agree with slaphead20. If you use a lot of wi-fi or 3G, or play a lot, keep the screen very bright, or if the network signal is weak, the battery goes very fast.
There are many articles on the net talking about this, and right here in XDA.
Enjoy, sorry for my poor english.

Devil3 set to power saver mode is one of the best I've tried imo. I recommend investing in a polarcell battery too.

But don't forget the kernel cleaning script before you flashing and testing a new kernel.

I asked about the one with the best battery life, not the one that "nice to look at".

Hi,
During the time I tried plenty of kernels and roms, I was very impressed by the galaxy EE kernel for the battery life. With normal usage (phone, sms, download, games) but without 3g, my battery lasted around 4 days.

About the rom, I did not test myself, but heared a lot of positive feedback for GingerReal2, which is very stable and smooth http://forum.xda-developers.com/showthread.php?t=1155623
If the rom is very responsive and does not have plenty of candy and shiny fireworks, this would mean you can tune your cpu with lower speed, which will lower the battery consumption (which is possible with galaxian kernel)
I hope it helped you ;-)
Have fun !
P.S. I am surprised that you have bad battery life with CM7, because it is a very good one for that point if I remember well... Did you try to tweak the system when you installed it ?
I have had cyanogenmod 7 and miui and try a lot of kernels!
Cm7 is very good also with stock kernel, but I think that Cyanofortomorrow v1.2 is very good! You can dwl it with stock kernel or with platypus kernel.
Miui is very nice but battery life is not the best! I have a mintberry rom with glitch kernel v13.
The best kernel in my opinion are glith kernel V13 HL (smartassv2, sleep governov powersave) and platipus neo 18 didle (deep idle). For less battery drain it's very important understand wich modem phone is better for your geographic area and operator.

Best Rom for battery life?

Hello Guys,
I'd like to know your favorite Rom ever for battery life, I don't care if it ugly or with bugs, I just want the best Rom for my battery.
thx
(and sorry for my bad english)

you might wanna look more at a kernel that's is what makes the battery life better also reset battery stats in cwm recovery

I find stock roms have the best battery life. If you really want to push it, get a basic rooted kernel w/ clock speeds (semaphore), and underclock your phone to maybe 800mhz.
try using a stock rom and a good root (semaphore/galaxian) and use low light display and underclock the cpu
Thx guys, I'm gonna try that, (sorry to respond 1month later lol)

can you please explain more about underclock your phone to maybe 800mhz
I use simplicity with special configurations in the semaphore kernel:
- Underclocking to 800MHz
- Simple-IO
- batterysave Governor
- autobrightness to dark
- darker-Voodoo Color
I also switch off Network and Auto-Sync with help of widgetsoid (see market) when not in use.

Hey, sindalf, what version are you running, I was on 2.11 using fugu(I think) kernel v3189, and my battery is not very good.
any rom with removed bloatware such as CM7 and others
try gamerz rom that is brilliant for bat life and removed bloatware
Back in the day that I didn't used MIUI ROM's I used Darky's and that battery life was great! Also the ROM was blazing fast.
Last version I used from Darky's was 10.2 or something like that (V10 for sure). Had about 2 till 3 days battery life. With slightly less usage than normal. And i must tell you that when I flashed that ROM i jys had a new battery.

What Is Best ROM For Battry ?

Hello anyone pleas tell me witch ROM is good battry wise i am cruntly on 2.2.1 and it lasts 4 5 hrs on web browsing
Short answer, insanity froyo.
I remember finding the old Serendipity 6.4 Froyo ROM with JPE modem really good. Currently using SURFACE JPZ with SpeedMod kernel and that's been great too. Web browsing is best done with screen brightness as low as possible, or by using Cyanogen's browser with the colour inversion feature. Most web sites have a white background, which is the most battery intensive colour to display on the Galaxy's AMOLED screen
you can try XXJVT,this rom has stable,fast and long battery life.
I'm not suggesting ics because gingerbread's battery life is longer than ics
Better ROM, don't know, but the worse rom for battery is ics! Don't flash this if you want a good rom with good battery life

JS8 is the best firmware!
General Advice
the following advice is independent from ROM & Kernel:
If you do not use Wi-Fi, then shut down.
If you do not often surf with phone, so turn the traffic off or switch just from 2G to 3G.
If one does not use Bluetooth, then switch off.
If you can well see the display Content, then you should reduce the brightness levels.
You should not run unnecessary apps in the background. The Best Way to do is over a Task-Manager-App. There you shoud kill all running processes and then immediately press Standby - button.
Always unload the battery fully and charge the battery fully

JVT with JVU-modem and Talonkernel works fine for me. Charging bug sucks, but besides that it is the best combo regarding performance and battery.

I'd agree with above post. DarkyROM is very good for battery.
I think: Dark Knight 3 and ARIO ROM 2.2 ICS
Ario rom 2.2 ics
I am satisfied with Teamhacksung's ROM
________________________________________
I was on the AOKP port, with Semaphore kernel and it's governer set to savebattery. It's an excellent rom and I got two days. Two days itself isn't all that impressive, but it is considering I had everything installed, running and syncing. So that's the best I had so far.

Everybody will tell you to use whatever rom they like.
You should just try them on your own and decide yourself which one works best/has better battery life for your personal use.

Well, personally I like Slim ICS as it is, with the kernel that comes with it.
I also used Semaphore for a while with Slim ICS, it has more customization, but didn't really notice a any significant battery life change.

edit: wow.. triple posting, sorry for that, xda went down for a while.
I too am running on Slim ICS + Semaphore 1.3.0s kernel, i am getting a pretty good battery life with combination of Smartass v2 governor + Deep Idle enabled + Juicedefender + low screen brightness settings. I cant give you any numbers right now but lets say that if i unplug my phone at 12am and have a moderate usage ( phone calls, texts, browsing, fb, whatsapp, maybe a little bit music) i will have +- 50% battery left at 12pm

I am using SAmsung Stock ICS 4.0.4 with Philz kernel. I have no problems with the battery.
BurtROM LSZ and PhilZ LSZ = PERFORMANCE AND BATTERY PERFECT.:good:
Rightnow my note is running on jellybam it can stand for day with fair usage

It depends on how you define poor.
There's the usual things to do, you can undervolt to help, throttle the top end, get better battery stats to check for wake locks, make sure gps /wifi /bluetooth /sync aren't on when you don't need them. Turn down screen brightness as that probably the biggest drain on battery, so using apps with light background isn't great.
You can use different governor / scheduler combo. Some people say pegasusq /sio is a good one. Some apps help either by turning off services you don't need while your not using your phone or by adding tweaks to help efficiency.
Use search for battery tips as there's a lot of information out there.
That said there's always the old gem of 'new battery' depending on how old her note is. Remember there are larger than 2500mAh batteries out there, although above a certain point the battery gets thick and comes with a new back to help contain it.
Hope that helps.
