Best Combination (Kernel + Rom) For Best Battery Life (Q) - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Hey guys, atm i use the CocaCola rom and the kernel that comes with it i think is fauxs kernel.
My battery life is pretty harsh and is down to 30% by like 4oclock everyday so i gotta charge it again
I'm just wondering what kernel and rom u guys prefer for the best battery performance
i realize the rom doesn't effect the battery life but just throw out which one u guys prefer

I like the faux kernel but its not really a battery saver unless you underclock and underovolt it seeing as it is overclocked be default. If you use things like bln then the "stockish" kernel has those features. Or you can flash the stock kernel over the rom which will give you good performance/batt seeing as this phone is no slouch by default. I fiddle back and forth.

I under clock mine close to 1000ghz and it still smooth as ice

need advice about the current roms

Ok, ive been doing some research and it looks like eagals blood is prob the rom for me. I was wondering if i could get some advice on this, i am currently unrooted so im stock , this phone is killing me when it comes to battery life, the stability is so so, but my real problem is battery life i charge my fone about 3 times a day. I am a crazy heavy user, fb, texting about 200-400 message a day, phone calls every now and then, games (words with friends), and just random internet stuff. so my phone is like my life! My friend has a samsung captivate and he can go 12-14 of heavy usage prob not as much as me but he doesnt have it charging all the time like me. I was wondering what rom i should use to achieve great battery life and not lose out on stabilty or speed, look doesnt matter bc i use UTO kitchen.
Are you looking for an Android 2.3.3 or 2.3.5 ROM?

Hey man if you want a 2.3.3 rom that is stock the best is Xboarders stock tweeked rom it is super stable and everything works and the battery life is great. I use that ROM myself when I am in a stock mood. You hit it on the head with eaglesblood it is the best rom out there. I use the 1.08 verion it is based off GB 2.3.5 it is a mix a cm7 and EB goodness. The battery life is also excellent on it but you will not have A2DP (thats BT stero music) And you cant flash the stock froyo LG camera and there are APN issues that A hard reboot fixes every time. All of the problems I just mentioned are not specific to EB they are however specific to GB 2.3.5 for the g2x. It has something to do with Nivdia not relesing something drivers or sorce I dont know what exactly but thats why. You have to make a choice. I hope this helps you. Oh I alklmost forgot I am a heavy user like you except not text mssgs or phone calls but net data data data I had to change my plan to the 10 gig plan 5 was not enough. So what I did was I got the extended battery for the O2x it fits perfdectly and it was only $30. Before that I had 2 stock batterys with an external charger that worked ok too but I hated changing the battery half way through the day you should look into that. Good luck man.

i dont mind i want something stable, fast and great battery life...what does A2DP mean...im going to try EB 1.07 bc i hear no1 has problems with that...
A2DP is Stereo Bluetooth Audio... That's only important if you listen to music using a Stereo Bluetooth Headset.
For battery life, I'd recommend a CM7 based ROM, with either a stock, or undervolted kernel, such as faux123.

When u undervolte does it slow does ur phones speed?

I agree with FatalityBoyZahy,
I did see a battery life increase after installing CM7, but the most dramatic change in battery life came after installing faux's 0.4.1 undervolted kernel.
And no the speed and stability don't drop, at least not with faux's kernel.
I would imagine that a 2.3.3 stock GB based rom such as Xboarder's tweaked or EB 2.3.3 plus faux's stock GB kernel would produce the best battery life, as I remember experiencing a huge jump in battery life from CM7 to stock GB.
However, I feel like besides the great battery life, the stock GB roms are ****ty compared to CM7 in terms off features and stability.
For example you can't do Netflix or gtalk video on stock GB.
Also I didn't experience this, but some users experience reboots and other such nonsense on stock GB.
So in Summary:
- stock 2.3.3 based rom (EB 2.3.3 is your best bet here in my opinion) + faux kernel = best battery life
- cm7 based rom (EB 2.3.5 or latest CM7 nightly) + faux kernel = best choice for both great battery life and better stability/features
Hope this helps!

There is only a handful of roms for the g2x . Some of them are no longer being supported by the devs as they have moved on to other devices it seems. just give them all a try.

No. The only risk is that you might run into stability issues, but using morfic's UV11 it isn't an issue.
Undervolt, use SetCPU profiles, keep wifi/gps off when you're not using them, and keep your display brightness low. That will net you the best battery life.

I believe the faux kernel is here: [Kernel]CM7 [2.6.32.45] (v0.4.1) OC~1.55GHz/UV/SLQB/BFQ/EXT4/Voodoo [Aug-27]
Looks like the CM version of the kernel is preferred by some in that thread (has to do with the battery driver).
Question: In terms of flashing the kernel, should I flash the ROM first and then the kernel? Or the other way around? (Or does it not matter?)

Always ROM then kernel.
And I prefer the CM version of faux's kernel as well. Supposedly the DS version has better battery life but I've never been able to notice because I'm always busy pulling my hair out over the jumpy and wildly inaccurate readings.

[Q] Nexus S rooted -> now I need a good Kernel

Hey fellow XDA's
Having recently rooted my Nexus S (i9023, LCD version running 2.3.4 Gingerbread) I'm looking at the next logical step which is to install a kernel that will improve on my experience so far with the Stock Nexus for the past 4 months or so. I like the Stock experience so I'm not looking into a ROM.
However, regarding the stock Android, I realized that the video recording audio quality truly sucks...
.. and it's obvious the lack of a notification light can be a problem ...
... and the battery life whilst good is not incredible, still need to charge every night.
So what I need is to install Voodoo sound for the sound, BLN for the notification light.. and the battery life "improvement" could come from underclocking the CPU... (I could maybe overclock but really does it change anything in real life other than quadrant scores ?)
I've noticed so far that there's quite a few Kernel builds around, but some of them seem to have more stuff than I need. While this might be a good thing, I also want to keep it simple. I like the Stock 2.3.4 so I don't really need Voodoo colors for example. Also some users seem to report worsening of battery life with some of the custom kernels... (but you can't believe everything you read on the interwebz I suppose..)
It seems that I can either pick NetArchy, Lucid or Matrix kernels. Which one would be the simplest for me ? I don't need to have kernel features that I won't use.. I'm not looking to overclock the phone.. maybe underclock to help battery life when it's just sitting still!
Thanks a lot for any thoughts guys!
Take trinity miui kernel tuv10 1ghz, up to 3700 in quadrant. And it is under volt kernel. The voltage is lower than stock and probably save you battery.
If you wanted to save more juice, take 880mhz or known as teuv. Your quadrant still can reach up to 3300 with a very low voltage and stable kernel.
It comes with latest voodoo. I enjoy the sound very well.

You talk about saving battery life and leave out the most obvious, Trinity kernel, TUV or TEUV.
if you are on stock 2.3.4 i'll suggest Netarchy 1.3.7 stanble, the fastest and smoothest
if you plan to flash CM7 or some of its derivatives then i'll suggest Trinity TUV10
yep stock kernel 2.3.4 for european variant. I don't plan to use CM7 (yet)... but I guess I'll just do a NANDroid backup of my rooted Nexus with stock kernel and then both NetArchy and Trinity... see which one is best for my usage
Trinity is not that great on stock 2.3.4
i tried that already, but it's definitely best to try by yourself and see which one you like better
Just installed NetArchy CFS... so far so good. Downloaded Voodoo Control and BLN and it seems to work well. No issues breaking existing functionality... going to run it for a few days, see how the battery holds! Enjoying the sound and the back light notifications!!

2198 quadrant score... it's an improvement, but then again overclocking the CPU was never part of my plans so I'm happy

[Q] Best ROM for battery...

Which ROM, as your experience is the best for battery usage?
I mean.... doing the same use of phone, which ROM drain less the battery?
Thanks
I have found that brainmaster's MIUI is very good with the special trinity extra UV kernel by morfic

[Q] Battery efficient rom+kernel?

hi
sorry for being such a nooby mcnooby-pants
but i just want to know which combination of roms and kernels will give me a great battery life and at the same time i want to be able to overclock to 1.5 GHz
i looked through the forums and i did all the basic stuff like
undervolting
setting profiles in setcpu
and removing all the bloatware from the phone
but everyone has a different combination and im really confused as to which combination to use
right now im using eaglesblood 2.3.7 with the dragon kernel and its really not working very well
so any and all help will be appreciated
thank you

My opinion:
1. Jump on a stock-based ROM with stock kernel and UC (underclock to 900-800 Mhz, you would be surprised you notice very little change in performance). Most stock-based ROM users report back great battery life.
2. Jump on a CM7 Nightly 199 or higher (Reports of great battery life, I can attest to this) with morfic or faux123's kernel (I prefer morfic's) which you can undervolt easily with Pimp My CPU (search XDA). I prefer it to SetCPU because the only profile I use is UC when the screen is off and with Tegra's DVFS CPU governor, it already does a good job of doing this. I also UC with this setup.
Delete Wi-Fi Calling (Kineto.apk) from your phone if you're not using it. I learned this from lotherius, it's always running in the background even when off and not in use. I was shocked to see the improvement.
I know it sounds stupid, but if you're in class or at work and don't need a barrage of updates on your phone, just turn off data. Most ROMs have a quick toggle setting to efficiently turn it on and off quickly and you'll be quite happy with how long it lasts. If you have to have data on or think it's moronic to have an Android phone that's not does not always have a data connection, battery drain is just the price that is payed.
woah.
Awesome answer
so do you think option 1 is better or 2?
does using cm decrease the battery efficiency?
if it does do you think the extra functionality in cm makes up for the batteryloss?
Thanks btw
Try miui 1.11.4 from whitehawkx with faux kernel cm-4.4

Good question, and I think that is totally up to you.
For example, my father and I both own G2x's, he runs a modified stock ROM (xboarder's ROM) and I run CM7. Without a doubt he gets better battery life than me, but at the cost of not having the features I have.
That may be a rough way of putting it but yes, using CM7 with all it's awesome features come with the price of not being as battery efficient.
The real question is if being less "battery efficient" actually means it's a bad thing. In my case it doesn't matter to me at all. Using the quick panel toggles in CM7, I only turn on data when I need it and I easily pull 15+ hours a charge because of it, assuming moderate usage.
Consider lotherius's tsugi rom, currently in version beta 3. It is my daily driver, stable, faster than 2.3.3 based roms, and excellent battery life. He has included a 2G toggle app that can automatically switch to 2g radio when screen is off to save lots of juice.

Definitive best kernel/rom combo for battery? NS4g

I use my ns4g pretty heavily so I need a rom and kernel optimized for battery life. I'm looking for 3+ hours screen on time, something the ics roms/kernels I've had havent quite delivered. i dont wanna downgrade to gb, but I'd like to find a good combo of battery life and stability...

try this ics kernel, http://goo.gl/QAuKi its Trinity TEUV(TEI6S). its undervolted, underclocked at 880mhz, and its bus/gpu is overclocked 10% at 220mhz. its fast and great on battery. i use it with cm9, but it should be good with any ics rom
You don't even know lol ive tried and tested that decent battery but I can't live without the mods... solid performance tho

With all the mods, they r all good as well (icup speedy, matr1x, sg-uv etc.). The new franco.kernel is released and it runs very nice. It doesn't have mods yet but the battery life and performance are super. Also like simms said, the barebones trinity kernels are the best in battery life.
I'm running NexusBeam with franco's latest and I got like 25 hours of battery after average use.

TEUV All the way for battery performance
Matr1x v15.0 is out, has all the features and is undervolted.
I get 20-25 hours out of battery with around 4-5 hours screen on time.
Do you think using running CyberGR-MOD|NS.NGN ICS with Matr1x 14.5CFS, i could get decent battery life? i'm asking cuz i want to install ROM on Gf's phone, she still running CM7 from when i did last time, but i don't want to put a rom that lacks features. i want one feature rich that will not suck on battery life
I can't get over 2 hours screen on time MAX at all anymore. I'm running Peter Alfonso's Bugless Beast GB with GlaDOS 1.12 kernel undervolted to 880 MHz and 20% screen brightness. Even with a new Battery and a full wipe and clean install I still get terrible battery life. Anybody have any ideas? I'm dying here. Is my phone broken?
