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.

Hello,
I am a big noob - when that has been said - I am happy about my Nexus S.
I own the EU model, I9023. I have downloaded and manually installed ICS (incremental), but it seems like it uses as much power as GB.
I consider myself as a heavy user of my phone - I text a lot - 100, maybe more, pr day. I read news, emails and so on from my cellphone. My battery will last for maybe 12 hours before I start to conserve the battery.
I have tweaked, deactivated all sync except Google, optimized within the stock rom (without root).
I have read that you can do a lot of things to your phone to help this. I have looked at ebay and amazon for a replacement battery, but all of them fits 9020 and not the 9023 (expect those costing way beyond 70-80$ + shipping)
I have read that there is some kernels for android which is using more features to help improving the battery life. So, I have tried to get an overview, but the lists of kernels and roms are very extensive and I cannot tell difference as I am not expert in android roms and kernels.
I weight stability and usability - therefore, I have no needs for fancy features - stock rom is fine or something like that, if needed. I have read about the deep idle feature which sounds like a very big issue that stock android does not have implemented. So I am looking for a kernel which is stable and can help me improve my battery life (if possibly).
As I have not rooted my Nexus S or anything before, I would also ask if someone could make/link to a step by step guide to rooting and installing it. I can see a lot of methods for rooting nexus s in this forum, but I would prefer one which is fairly simple and is confirmed working with android 4.0.3
Thank you for your help
Turn off auto sync on apps like Facebook and Widgets. Calibrate your batt every once in a while. Get a kick ass kernel like speedy or matr1x.
Would matrix kernel work with ICS 4.0.3 stock, but rooted?
Hi,
You really should root your Nexus. I was on stock ICS before and had barely a day of battery. Now I'm on Petes Buggless Beast with steven garons kernel. I Love it, everything runs flawless, stable, smooth(better than stock) and with medium usage i have 2 days with my nexus. Even more when i only do some calls and some pulse reading and some maps usage.
Youll find all the guides you need in the general section.
Here are some pics of my battery with little usage.
Hello,
I have now rooted and installed Matr1x kernel.
Then I am running stock 4.0.3 with Matr1x kernel. I downloaded NStools and activated Deep Idle. Lets see if that will improve my battery time
I am looking for a rom that handle me using my phone all day and not dying. I would love to find a rom that possibly allowed you to turn off the lte or whatever. As long as i dont have to charge my phone 3 times a day. Can anyone help me out?
many topics posted on this, the search feature is ur friend
My opinion
Seanscreams skyscreamsandwich rom has excellent battery life, I think if you try that with the new UCLA kernel you'll be very happy.
I have the stock Rogers ROM, rooted with CWM installed. I installed updated stock UCLA radio and kernel last week to get the benefits of latest kernel. Worked great but I've never been thrilled with battery life so Saturday I flashed Faux kernel v. 9m I think it was, on top of stock ROM and new updated stock radio.
Installed Set CPU to control new scalable speed kernel. I'm not easy to impress but it's absolutely unbelievable. Set to a conservative profile I've got blazing speed and 50% better battery life after 2 days use.
Go for it but don't do any playing before installing custom recovery ( CWM) and making a Nandroid backup.

The Skyrocket has respectable battery life, consideeing its LTE and 4.5",screen. A ROM is not yoir solution to getting extended battery life out of your phone. While some ROMs are more battery friendly than others, there are better alternatives. Juice Defender seems to be really popular and successful at prolonging battery life.

Here's a link to the thread. I'm sure there are others like it. I definitely learned a lot:
http://forum.xda-developers.com/showthread.php?t=1524291
Needless to say before any of that is done, you wanna make sure the following is done first:
1. Make sure your phone is rooted and have Clockwork mod setup.
2. Do a nandroid backup.
Hope this helps.
Sorry if you guys has been asked about this question for the nth times, I'm new to this phone and I'm a total noob in Android.
So, here's my scenario, I have this Samsung Nexus S Version M200 running currently in CM 10.1 Nightly firmware. It's good as far as I'm using it but I'm having a problem with the battery life. I usually charge it 2 times a day. What I do with my phone? Mostly play games and it will only last 3-4 hours max play then I have to charge it again. But to summarize it it will not last a whole day even with normal use, minimal games.
The question now is:
Should I go to Official ROM?
If yes, which version with long lasting battery with GPS and other services on and playing games max?
If no, should I stick to CM 10.1?
If no with CM 10.1, which ROM should I install?
Thanks in advance, I actually have a lot of questions since I'm so curious and want to know more about this phone, but I'll just add it later.
Don't worry since you're new no one will get mad.
Anyways, there won't be that huge of a battery life difference between most of these roms, it just depends how your settings are and how you are using your phone. I've tried most of the roms for the NS and I can tell you my team favorites are CM 10.1 Stable with Marmite 8.7 Bigmem kernel and JellyShot with the same kernel. Those two have given me the best stability+performance+speed+battery life combo.
The way you setup your cpu governer and i/o scheduler as well as some developer settings and a few more things can definitely make an impact on increasing battery life. Here's how I have my phone setup:
ROM: CM 10.1 Stable
Kernel: Marmite 8.7 Bigmem
Governer: During the day I use Smartassv2 with 100 min 1000 max, during the night I switch it to On Demand with 100 min 800 max
I/O: I find deadline to be the best and cfq to be the 2nd best especially if you are a person that has multiple apps in use its best for multitasking but if you're just doing one thing at a time (Youtube vids etc) stick with deadline
Developer: I set the 3 animation options all to OFF.
For your phone settings, if you don't need all those sync options on I'd turn them off, same goes for auto-sync/background data (you can find these options in data usage).
There are apps out there like Greenify which are great for saving you extra battery life, it puts apps to sleep when they're not in use. Try the free version it works great.
Lastly everything starts on how you first install your rom, I'd recommend a completely clean install. I use Philz Touch Recovery its free and you can find it here. The way I install roms is:
1. Wipe Data/Factory reset
2. Wipe Cache
3. Go to Mounts & Storage and format these: System, Data, Cache, Boot
4. Go to Advanced and wipe: Dalvik then Fix Permissions
5. Install order: Rom first, Gapps second, Kernel last
6. Reboot
Thats about all the tips I have. Sometimes your phones battery just doesn't cut it, some people claim to get 5 hours screen time etc, but I never get that kind of amazing battery life I think my battery just sucks. But mess around with those 2 roms I suggested and those settings, see if you like it. Goodluck.
Just bought a second hand S as a second phone and found your reply one of the most useful for setting it up so far. Thank you.

Thank you for the quick reply...
I have a follow up questions though. Hehehe.
1. How can I change my Kernel?
2. If I can change it, will I lost my data? What are the results? Because I've done a little search about Marmite and I've read it's good.
3. What's Governor? LOL Sorry, I'm total newbie. I don't get it. And the Developer? Haha!
4. If I do a clean install what would happen to my data? Does all my app data will be lost?
So far that's what's in my mind. I'll follow up again! Thanks! You're a big help!
@purpse You're welcome, glad I could be of some help.
@khimois
1. Well to change kernel you first need to download the proper one, get the "cm" version of Marmite that means its for Cyanogenmod based roms. To install it you need to use a recovery. Something like Clockwork Recovery its free you can get it by installing the "Rom Manager" app. Basically recovery is a thing you boot into its kind of like safe mode for PC's, but this will let you install Roms/Kernels, etc.
2. You won't lose your data by flashing a new kernel but you will lose your data if you wipe data through the recovery mode. If you really want to keep your data and apps you can use an app like Titanium backup it backs up everything for you to install later after wipes.
3. CPU Governor is a just how your CPU is going to be functioning. There are a bunch of different settings you can choose from. Some for example: Conservative (this saves battery by using less cpu power it will clock at lower frequencies) also On Demand (this setting tells the cpu to only work based on the demand so if you're phones not doing anything it will clock to the lowest speed you set the "min" value to but if you're playing a game or something it will scale up towards your "max" value)
Developer options can be found after you go to "About Phone" and click on build number 7 times, then you can access developer options from the main settings menu. These options let you do a few cool things.
4. Yes a clean install would wipe your data and apps, its like a brand new phone. There are some apps like I mentioned "Titanium backup" which can help you save your apps and data, google about that to learn more if you're interested.
And no problem, glad to help, everyone is new at everything at some point. You're learn that flashing roms and kernels will become repetitive you will always want to try new ones and then it just becomes so easy to do.
On most android devices Jelly Bean consumes twice as much battery as compared to Ice Cream Sandwich. You might want to consider downgrading if battery life is your top priority.

Thanks for the great help, I'm still in the process of absorbing it. Sorry, I have follow up questions:
So, if I want to clean install everything? What should I do? What are the things I need to consider? What are the things I need to backup?
I have an existing ClockWorkRecovery v6.0.0.6, is it okay to use this? Or should I update it?
What are the risk in updating ClockWorkRecovery?
EDIT: Can you also provide me a link for Marmite? I can't seem to find it. Thanks!

First of all we are here at the nexus S forum it doesnt matter what the whole population is experiencing in regards to jelly bean, we dont have any serious battery life difference on the nexus S with ICS and jelly bean.
And I doubt any phone has DOUBLE the battery life difference.

I got friends who own these devices: Karbonn A9+, Innos D9, Galaxy Note
Their batteries last for a little less than a day on normal use (wifi, sms, some gaming, etc.) as compared to 2+ days when they were on ICS. They don't complain that much because they like the smoothness of JB.

Just stick with the stock rooted rom for a month . Then you may flash new roms ..
The battery life is the same for ICS and JB .. But standby battery backup has been improved in jellybean...
But free ram vaialable will be lower in JB after flashing gapps package..
The three roms which I will suggest you are 1. Xenon HD stable(mix of slimbean,aosp,cm,pa) 2.Slimbean(sleek and black) 3.Carbon Rom
And use Marmite kernal non cm version for the above roms.. Alrthough Slimbean comes with latest marmite kernel..
I have always been with stock.
Few options that saved battery life:
1. If you have apps that turn on GPS when the app is not running (like Life360), its best to turn off the GPS when you are not using it. Power Control widget helps a lot here.
2. Turn off Wifi & mobile network Location under Settings->Location Access.
3. Turn off Google Now
4. Turn off Background Location Reporting for Google Maps.
5. Uninstall Facebook app. (the messenger app is ok)
My phone have gone from being left with 20% after 8 hours to around 60% after I have done the above. If you are having an old phone, consider getting a new battery as well, since the stock battery would probably be at least 2 years old by now.

Agree.
I am using Nexus S with lastest CM 10.1 (release)
You might want to avoid :
Google now
Localisation (using GSM or Wifi)
Facebook : it is such a RAM eater it will have side effects on all the others apps, better use web app or Friendcaster
If you don't mind, de-activate 3G when you don't need it
Generally speaking, avoid large memory footprint apps, use opera (classic) as your daily browser and tune notifications.
Best one that I tried is Marmite kernel.
Also you need have a task manager to kill programs/
Also It's DisableService application is a must.
Hey guys. I have a VZW Galaxy SIII, as you know, and the battery life has been quite bad for the longest time. Any suggestions as to what kernel I should use? I'm currently running CM10.1.3, but I plan on updating to KitKang (Unofficial 4.4). Thanks!
This guys kernel is pretty good, i can get a full 8 hours or better depending on the type of usage.

Since we're suggesting apps Greenify works pretty good for me. Probably got me a couple more hours. It kind of works like Titanium Backup's freeze option. You choose what you want to greenify and it "freezes" them until you start them yourself. Then puts them back to sleep when you exit.
Don't know if you look but there's a ton of crap running that doesn't need to be all the time. Reminds me of msconfig.
https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
"best" in roms and kernels is dependent on a variety of factors...to include settings and signal amongst other things.. Please take a look and try them all to determine what it is you need.
