Ok - I normally don't use a kernel, but my battery life blows on ICS.
Anyone have a suggesstion for the NS4G?
I'd like to avoid overclocking, but I guess if the kernel has it, I can revert to stock with setcpu.
Thanks!
Depends on what you define as good battery life. I manage 17 hours, which is fine by my standards with my usage pattern. Some people can pull a day with normal use and I mean 24 hours on stock battery. I've stuck with Matr1x because it has what I want in a kernel. Stability, decent battery life, a variety of governors to toy with, and Voodoo sound . I'd say give it a go. There are so many out there and I've messed with a few. The life hasn't really changed between them though. It just seems Matr1x hasn't given me any issues.
For stock, thalamus provides an optimised stock kernel.

Pick your poison. It doesn't have all the voodoo, bld, etc, but I get 18 hrs with about 3 hrs of screen time on it.
Trinity kernels are also excellent and their colours are spectacular. They have all the bells and whistles.
Ultimately it's up to you though. Try a few (after you've made a backup of course) and you can always go back should you encounter any issues.

I also would say Matr1x, I was able to get 5 hours screen on time with 15 hours of total use yesterday, not sure if you will get the same result on stock but it should help

I'm looking for a ROM which can make my device hit at least 24 hours with light/moderate use. I know it's based on how the much the user interacts with the phone, signal strength, etc but there has to be a ROM which made your battery life amazing! I'm currently hitting about 12-14 hours with light to moderate use. I've seen people that use it the same amount and get nearly 2 days, how can I achieve this? I read somewhere that Pershoots kernel does well with extending battery life.
I'm currently on CM7 with the stock cm kernel.
Thanks for any helpful posts!
Okay so in my experience to get 'good" battery life with a g2 you need to turn off your push updates, stay off of data as much as possible, and only hook into wifi when you need it. Make sure your screen is on for no longer than 30 seconds, turn down your brightness, and set some profiles under setcpu to downclock you after you get to sub X battery life. Just make sure to increase the priority the lower your battery life goes.
The best and most consistent battery life figure I've gotten is 42-48 hr by generally not being a complete dickwad. If you flash a rom and have to download all your apps again it is going to suck you dry. I ran Cm6.1.1 with preshoots kernel for a goodly while and have pulled the same speed/battery life as I do on Virtuous with Advanced Kernel. It's taken a couple days for it to settle in but yeah, you're looking at 42ish with moderate net usage, full signal, and darn near constant texting.
Edit: Let me clarify. As your power goes down you should downclock in 5% increments. For every 5% less battery power you have, you need to increase the priority of that profile by 5%. Make a profile that is 100% priority but downclocks your cpu to 350ish max and 200ish min. Also something to keep in mind is that every piece of hardware is different. Some people can report fantastic life on the same kernel and OS. Just one of those weird machine god things.

I can get a day and a half with team villian sense ginger. The one before 3.0 best battery life i have seen yet. This is a 1.5days with constant OC no screen profiles or any kind of battery saving profiles. I would say im a slighty less then heavy user. Wifi always runs and i use gps for about an hour depending where im going. Now i normally charge her up every night but i have forgotten on ocasion and made it till i got home from work the next day.

+1 on villan rom, i set an off screen OC to 300MHZ and an on screen to 1.5Ghz, and i get 20+ hours out of it with mild data. wifi off unless im home and location always turned off unless i need it.
Might give that villian rom a try, is there a specific kernel I should use? Or should I just use the one that's already on the villian rom?
Sent from my HTC Vision using XDA App
just download from the current thread, the 1.5 version, it has an kernel that OC's to 1.5GHZ and works well.
i would download as is, and if you like, play with the kernel later on if you really want to.
Or if you like sense get sense ginger. Im not sure how you can get the older version but you could try the new one.

He is right, but lots of us has been through several ROMs and I can say that from the look of it all the ROMs use lots of battery life due to all the running processes. If you end up finding a ROM that supports your needs post it and let everyone know. Hope I helped
i am sure there is a thread on here already for this but i can't seem to find it i am looking for the best kernal and rom combo with the ultimate battery life with also o.c. supportive as well i am wondering what is it that i can do or flash i am currently running g.b. stock rom with a cynobenmod kernal i am wondering what everyone else best experience is also batteries ext. does anyone have a great cheap battery that extended there life on the evo i use tethering about 5 hours a day and i really need that to work to last all day and making 6-7 phone calls thorugh out that day just so you know i am using a evo 4g
if you don't mind AOSP-based ROMs, try Deck's ROM ([6-21-11][ROM] gingerbread-evo-deck [1.2][2.3.4 Stable] - xda-developers) and then flash a Tiamat kernel (I've been using the latest and its been great) ([Kernel][AOSP] Tiamat | 2.6.38.8 | 6/6/11 -xda-developers). You can also try viperboy's undervolt mod [MOD]viperMOD for AOSP Kernels - v3 beta RC2.4 |Updated 6.14.11|*App in Progress!* - xda-developers on top of the kernel...helps out with battery life. Try the -100mv first then step down gradually till your phone is stable again
I agree with cg about decks and viperboys script. I personally get better battery life and performance with savagedzen. Also try underclocking down to 691....I do and notice no slowdown.
I have been using MikG v2.15 and battery life has never been better. Also it is far more stable than the custom kernels with voltage tweakers in my experience.
+1 to what Ronnie said. I like leaving as much stock as possible. I am running MikG 2.2 and never have to worry about a charger.

I've used MikG, Synergy, KingsROM, etc. (essentially all of the GB Sense-based ROMs that were 2.1/3.0 hybrids). And yea MikG had the best battery life compared to the others but I would only get maybe 12 hours out of it. What are your settings??
I'm with the Deck's crowd here. I use Deck's with Tiamat 3.3.7 (too lazy to try the newer versions), and I don't usually hit 50% battery life till about 18-ish hours off charger with constant texting/Tweetdeck/push notifications and a few phone calls.
I am not using any special settings or tweaks. Using Google sync to access 4 email accounts, etc. Also I unchecked the Always On Mobile Data setting.
It has been 100% stable - no stalls, connectivity issues, or anything like that.
Nice thing about MikG is that it uses Sense.
Decks and the latest tiamat sbc w viper boy....2600 mah battery I'll get 40hrs

Try MIUI's newest release...not sure what it is off the top of my head. Definitely the best battery life I've ever gotten. Get a solid 15 -16 hours with medium to heavy usage. (fbook,youtube, calls, texting, web browsing, downloading).
Im with you - Im on MikG now I love the ROM but I do not even get 12 hours with a 3500 mah battery. That is on a heavy usage day on low usage days I get 18 houirs. Not horrible but not good. Was actually looking for a sense based ROM with better battery.
Cyanogenmod 7 with tiamat kernel, stable version gives me great performance and stability and GREAT battery life.
Check my sig for my setup, I am currently using my AOSP setup. I get at least a day with heavy usage, stock battery. I use Juice Defender too, it seems to work well, especially with AOSP ROMs.
Radios matter too, if you have high Android System usage or cell standby, flash some new radios.

Hello all
I have been roaming around XDA for a very long time now and I finally made an account because I simply cannot find an answer. I have a samsung vibrant and not the 4g nor can I upgrade(long story). I use my phone when I need it and i text alot. But lately my battery life hasn't been any good, I've tried reconditioning and the whole bit and nothing seems to give me my needed battery life. I am currently using ICS passion 13 RC1 and it works great, when Im not doing anything -.-; When I use it like for the internet or text a lot it drains. I got to 48% in 2 hours one time and thats with limited background processes. I know ALL about the keeping background proccesses and data using apps down so I hardly have any apps installed, which is very irritating at times, I dont even use the facebook app for that reason. I tried many different roms and it seemed Axura had done that best at one point but it was taken down or is no longer supported for whatever reason so I am now in search for a rom that can get me through the day. I text a lot and web browse occasionally. I dont have wifi so i cannot use that to save battery life while surfing so thats out. I would appreciate all the help and will try every rom if i have to lol XD
I appologize for the long message but I am so tired of hesitating to use my phone as a smart phone.
I get good battery life on the ICS Euphoria ROM. Your battery could be shot, you might try replacing it.
Any of the 2.3 or newer roms are going to get bad battery life. Fishmanmod's updating of Bionics has been very smooth and getting great battery life for me.
I find that battery life between 2.2 and ics is pretty much identical for me as long as there are no wakelocks preventing deep sleep. I'm currently on CM9 nightly w/ glitch kernel and deep idle enabled in nstools and have no battery life problems.
You could also look into getting an official 1800mah battery if you really need more juice
ICS Slim hands down the best.

Your issue is Passion. That ROM chews through battery worse than any I've ever used in the 2 years I've had my phone.

Its not just your Rom, I am on the CM9 nightly and noticed ICS ate my battery by noon today. I was down to 3% from 7am. Granted I am toying with it a bit more but I was still at work so I couldnt use it non stop and I wasnt even watching videos or listening to music on it. I have updated the kernel to SubZero 34 to see if that helps.
Chances are, your battery has lost some of its ability to hold a charge. I recommend buying a new OEM battery, chances are it'll increase your battery life by a good two or three hours.
So far, I haven't noticed a significant variation in battery use in various ROMs, I've found battery life to be more determined by the kernel.

On a side note, I destroyed my screen by stepping on it a few weeks ago. Ordered a new AMOLED screen (not the LCD knockoffs) and battery life did in crease by about 3-4 hours. Same OS, same battery.
So I think some excess drain could be caused by the screen, which might explain why some phones had such poor battery and others don't. I also no longer have the "graying/shadow" issue that plagues some of these phone.
So far ive had the best battery life with ICS passion RC2.1 and my 1800mah anker battery
Since flashing CM9 and then putting on the SubZero kernel (34) I did a full charge and decharge to test and got 12+ hours on it with my normal use. So I have to say SubZero kernel really helps out if you are on ICS.
I f you dont mind going back to a 2.2 rom I would suggest trying bionix 1.3.1 fishmanMod or Deranged9 fishmanMod alpha 1 both get awesome battery life especially when mixed with juice defender.
I was also using ICS Passion and noticed a significant degradation in available battery life. I have three batteries so I'm confident it was the From. Until then I had been using various Froyo rooms and all seemed to have better battery life than ICS. I personally felt it was more likely to be your kernel choice that would impact battery life. I just switched to the SLIM ICS from and I gave been very impressed with both the battery and the responsiveness. Same quadrant scores as Passion but it feels so much faster

I haven't taken the dive into ICS yet i may have to try that out.
If you r searching for nice n smooth rom try
[4.0.4][6-Apr]Slim ICS [3.2]
http://forum.xda-developers.com/showthread.php?t=1520919
another thing you can do while flashing wipe battery stats only once....then reboot to normal drain your battery till it reaches 1% charge it full widout any interruption and when it reaches to 100% unplug it and do the calibration from any software available in the market I use Battery Calibration Professionals
https://play.google.com/store/apps/...2ZmZXNpb25hbHMuYmF0dGVyeS5jYWxsaWJyYXRpb24iXQ..
repeat the process for atleast 3 days in a row and you will feel the difference..hit thanks if it helps
@OP ICS is simply not battery friendly. You're going to want to use froyo if battery life is that important to you.
Or you can build a battery friendly ICS rom and let us know how it all is
The later builds of Cyanogenmod9 I have been on the stock kernel and its going all day with moderate use without battery issues.

Bionix Fishman Mod is the first custom ROM I've ever installed on my phone and it's battery life is AWESOME. I recently added an 1800 mah battery and I've had 24+ hours on one charge with moderate to heavy use. The ROM itself is smooth as glass and no glitches to speak of.

I just installed bionix-V FishmanMod Final 3. Fingers crossed. I don't mind switching back to 2.2 as long as I have better battery. However I did notice when I reinstalled ICS before going to bionix that just factory, not even logging into the market. I got 1 day and 7 hours of battery life, granted I did not do much but text occasionally and some web browsing here and there. Is it possible that the android market is constantly checking on stuff or there is some data being proccessed constantly? I do live in an area where my signal is not great for 3g like 1-2 bars.

Alright so after about a day with the rom, I noticed it's just as bad. I am still getting battery drain and yes I have a new battery in so it is not that. I unplugged it from around noon, did alot of working on it with reflashes and little bits of texting and mostly just scrolling around the O.S. im now at 44%. its been about 5 - 6 hours.
Although I have been switching the battery between 2 phones and their battery meter is very different. like a 5% difference so that may be confusing it. Will update.

Stock PA and matr1x kernel are both really good, with matr1x the battery life is about 5 hours screen, without screen it is just 1%/2 hrs.
I've tried franco and faux kernel too, but franco was a bit laggish and faux has terrible performance for me...slow ui, lots of framedrop in games...
There is no best kernel. All of them offer something a little different than the other. Some kernels work better with a ROM than others. My advice to to read up on them. Find out what you want out of it. Flash one and run it for a couple days. Make sure you let the battery drain past 20% then charge it without interrupting it. That's the surest way to gain maximum battery saving benefits. Just try them out until you find the one that's right for you. Happy flashing.
its actually made so that you dont have to worry about this stuff. kernel is just a cog. it twists and turns, who cares. unless you know exactly what youre missing of course. :cyclops:
Hi everyone! I am on the stock kitkat GNG8 and my battery is not good at all. I get arround 2 hours on screen time from a full charge in a day or less. I tried updating to Lollipop, but reverted because some of the bugs, and the battery was not that great either. I have 2 original samsung batteries, and both get drained pretty fast. Any rom/kernel confinguration that can get me at least 3 hours of battery life please? Thank you!
I'm using the Imperium ROM: http://forum.xda-developers.com/galaxy-s4/i9505-develop/rom-imperium-ll-v1-0-t3046889/page92
My best Kernel to avoid batery drains, was the Googy Kernel, and the settings as "Conservative".
But don't expect so much, I also get 100% charge, and in just a 5 minutes, I get about 90% (with a brand new batery and even another one 7200mAh with 8 months of use).
This sucks, I know, but it's what it is.
Avoid to get all the time the screen on, and sometimes power off the wireless/nfc/BT, or whatsoever connection that you wouldn't use it.

I'd recommend Danvdh's GPE rom. It has a nice battery life. I can't tell you how much screen time you will get 100-0% because I generally don't let it go under 50%.
But I can get around 2 hours, from 100% to 50% (while gaming) This is with wifi and bluetooth off. Screen brightness at the minimum and no vibrations.
Anyway. It's worth a try. And many people praise the rom. It's also the most bug and hassle free lollipop rom I've tried.
Or you can try any AOSP rom and Ktoonsez kernel. It's a really awesome kernel. Look in the Ktweaker shop and download some kernel profiles and switch between those. There are 3 categories: Conservative, Balanced, Performance. I guess they are self explanatory.
I used Sleeping-Dragon 1.2 Single Core (Basically turns your phone into a single core phone. It is still surprisingly smooth though) as my battery profile. There are several profiles for each category.
