Thoughts? AOKP 37 battery life - Samsung Galaxy Nexus

Hello this is my first topic that I have posted up, I am aware that there is hundreds of these same type of topics posted up, and I apologize for another one lol.
Just wanted to get thoughts from other members on these results on battery life through AOKP b37(stock kernel that comes with aokp, without touching the CPU settings)
CDMA (with extended battery)
Settings profile:
Basically followed every guide on turning off certain settings to save battery (GPS,wifi use,rotation,vibrate and etc.)
Brightness: 4O Percent
Wifi: 80-90 percent on
Few phone calls
Decent amount of texts
I know that there is a lot Rom/kernel combos and every phone will give different results, but searching through other posts I have noticed that Franco kernel give fantastic performance and battery life to many users and give recommendations to other users to use it.
To me still kinda scratching my head and uncertain if these are decent, bad or good results, and having opinions will help me understand better
PS. Sorry for grammar
Via Galaxy Nexus [LTE]

That's just fine for a CDMA Nexus. It might even be a little better.

[Q] Best GB ROM that has greatest battery life

I dont use my phone a lot and my TWAS is usually 0%. I dont use my phone alot, but usually when 5-6 hrs of no use or very light use it has gone down around 20-30%. Anyone have any ideas of what rom would work best for me? I am on ICS 5.0 right now and it seems they are not coming back with their 5.5 they had out. I really only care about great battery life and having some type of hotspot hack or free tethering.
Thanks.
You have to try each one and see what works best for you. Read the ROM threads. Every phone and user is different.

I have been using the latest sleeper rom and i have left it at 1000mhz no overclocking and i seem to be getting better battery life than i was with some of the others. i flash frequently and i would agree with kennyglass in that each one works differently. so try for youself.
Well, like everyone else said, its depends on what your phones handles. Everyone phones handles a rom differently, well, not that differently, but enough to make big differences.
Like the guy above me, I also use SleeperRom. Its a very stable, battery efficient rom.
here is a list of roms I would try out...
ACS_ICS_V5.5
LegendaryRom
MarcusantROM
StarskyROM1.5
I also recommend CleanGB by toadlife. Fast, clean, stable, full day on original stock battery.

Clean GB
My wifes phone while at work would drain in 8 hours to the point that it was saying charge me every day. Now with Clean GB on hers it lasts about 2 days with light usage. Again YMMV.
Im on clean GB and getting great battery life. After 11 hrs of moderate use I still have 30 % battery left. After 8 hours of heavy use I'm at 30%. Very stable ROM.. No force closes or wierd issues.

I personally would towards 'which kernel should I use?' You've got to remember that although we all have epics, not every CPU is the same. What I am running it he or she is running may not be what you should be running. If you ever check out an oc/uv thread, you will see that people get different results using different settings, even though we're all on epics. You've got to try a couple different setups (roms AND kernels) to see which runs best for your device. Good luck!

I currently use CleanGB which has been pretty great. If you're in an area with iffy service, that'll kill your phones battery pretty quick.
After installing a new rom make sure you charge it to 100%, wipe battery stats and then let it die without charging to get the most out of your battery (and having an accurate battery indicator)
In my opinion the way you configure your phone has by far the biggest effect on battery life, followed closely by the signal strength of the area you are in, with maybe a very small effect caused by the rom/kernel combination. Watch what you have syncing. Facebook and Twitter syncs can kill your battery, as can any other app that's always using data. Also, wifi uses WAY less battery than 3G or 4G. Use it when you can.
I'm on stock EI22 with mkasick's kernel and I usually get a full 16 hours with power to spare.

Basically Poit. Since no 2 people use their phone the same way it is retarded to ask for a comparison of best battery life. People need to stop being lazy and just try the ROMs out and compare for themselves based on their own use.

I agree. I have seen 3 questions over the last 2 days with these dumb questions.
but if I was to give my advice, I would strongly advise trying MarcusantROM, Battery life is pretty amazing, just be sure to flash a different kernel, as 2.0.6 is not even offered for download anymore because of bugs n such.
I would strongly advise the Shadow Kernel, paired up with MarcusantRom. You should see some pretty amazing battery life with that combo.
or try these out...
LegendaryROM
SleeperROM
Come on... "Dumb question"? "Lazy"? Get off your high horse. Certain ROMs give better battery performance than others because of certain tweaks and the OP asked for some general advice. Certain ROMs are certainly worse than others. OP wasn't asking for what would be best for him but what has worked good for others. Why is it so wrong for someone to ask for general advice about a ROM/Kernel combo. Not that hard of a question and not so ambiguous that it deserves a "dumb question" or "stop being lazy" response. If you don't want to help the OP, then simply DON'T RESPOND.
As for the question... I generally use the kernel that is included with the ROMs because normally that is what the developer has tested the most. I think Thunderhawk, Sleeper, and Legendary (in that order) are all good for battery but I haven't used all of the others.

In kind if you don't like the responses don't respond to them. I read for a month all the ROM threads before deciding on one to flash. Go to ANY ROM thread and someone there will claim they got the best battrery life there. It is different for every body and EVERY phone. ALL of the ROMs here have tweaks that work differently for everyone depending on use. Also people are sick of every other thread as "what's the best ROM". You HAVE to try them for yourself. If we are being to real for you then don't read what is written.
I was once where you are now. When I couldn't find a satisfactory answer, I made my own solution. I'll be uploading the latest version of it, version 3.3 today or tomorrow.
Battery Used: Extended Battery 2700 mah
Testing Performed: Idle Only
For those unsure, idle testing is simply when you treat your smartphone more like a phone. This included uses such as, checking the weather, responding to the occasional text, checking the time, etc. The primary goal of idle testing is to understand how long the phone can stay alive when used for texting and phone calls only. This is useful primarily for occasions such as, going on vacation, where you would like your phone to last a week or more in case of emergencies, but you'll be preoccupied and not killing your battery with Angry Birds. It's nice to know that our phone is capable older, simpler cellphones in standby time.
This indicates that my phone could stay on for as long as 10 to 14 days.
Direct arithmetic calculations indicate as much as 5.5 to 8 days on the stock 1500 mah battery.
Obviously, usage varies greatly between people and even between days, so anything other than idle testing is subjective. Testing was not performed on a stock installation, but rather, on my own daily personal fully-decked setup.
On the stock battery, I've played games for a total of more than 3 hours over a 48 hour time period before needing to recharge.
This has held true on my phone, my wife's, her mother's, and more than a thousand other user's phones. Yours may vary. Try them all. I do.
Looking forward to Random's latest!

Best Kernal for Battery life on Extended Battery

So just got my Galaxy Nexus on Verizon and already unlocked running stock 4.0.4 rooted. I got the extended battery (2100) and I am still kind of disappointed in battery life. I mean, even on 3G all day yesterday it lasted maybe 9 hrs. I have turned off a lot of background apps but still hasn't helped much.
Any suggestions on good rom's/kernels for the best battery life without having to sacrifice too much on the performance side?
Figure it out man.
Everyone (literally) is going to say something different here.
I'll vote Immoseon's 2.3.0 stable with stock clocks but dropped the vsels down by 100 personally.
Next guy will vote franco's.
Next guy will say popcorn.
^This man speaks the truth.
The problem with statements like "X kernal is best for all situations" is that it CANNOT be true. Kernal's will give you varying battery life depending on what you use them for. Since only you know what you do with your phone, you'll have to do some trial and error to figure out which one works best for you.
I, for example, browse fb, read some ebooks, and browse the internet randomly, I've found Franco's Kernal works best for me.
Perhaps a heavy gamer may be that to be untrue. Perhaps someone who takes lots of video/photos do not agree. But for my purposes, I am satisfied.
GL!
If the next vote is for popcorn I'll feel like a wizard

Lol yeah, another one of the "best kernel for blah blah" collection...
Adding my agreement to try them out and see. I like imoysen, but that is based on my usage.
One thing I will recommend is fully charge your phone before installing a new kernel, then wipe your dalvick and battery stats after installing. Then let it drain till it dies and fully recharge it in one go. Then evaluate your battery performance. It will give you a more accurate view of how it will perform. giving your phone a few days to settle into a kernel always helps, imo.

Hi. Can you give us some definite figures and how much better battery life you're getting (percentage or hours). I'm a new gnex owner and although I will definitely root my gnex eventually, I'm currently reading through all the threads regarding battery life.
I'm a moderate user myself - using it mostly as an e-reader with the occassional gaming, browsing, call and text. Right now I'm getting the following performance:
15% remaining at 13 hrs
4 to 4.5 hours display time
Like most users, my main concern when I root will be battery life.
Wiping battery stats does not improve battery life.

Best ROM/kernel combination for battery life

So I've been looking relentlessly for information on how to yield great battery life and for the most part, I've been successful.
However, I want to know what everyone's favorite ROM/kernel combination is in terms of yielding a good standby and screen on time. I got 11h off the charge and 3.6h of screen time.
I'm currently using CM9 with Franco's latest nightly. Dump your setups here. Feel free to include any tips on what you do to save battery life.
Sent from my Galaxy Nexus using XDA
it's an impossible question to answer specifically. The lower the frequency/voltage and more conservative the governor, the better life you'll have
There are already many threads discussing this, please refer to one of them instead of creating a new one.

Expected battery life improvements with a custom ROM

Hello,
My main criterion in deciding which of the many custom ROMs to go with is amount of battery life improvement I will have.
I see that the AHRD rom is the most popular, but does it also have the best battery life?
Or will the battery life improvements only occur when the source code is released and the One X runs on an ICS Kernel? I am under the impression that for some strange reason, the One X is running on a gingerbread kernel.
Thanks
This should properbly be in the Q&A section.
But anyway if you want great batterylife you should try Cyanogenmod. Those are the most basic ICS roms. Without any Sense gimmicks to suck the power.
That coupled with the Franco kernel should give you good battery life.
At the moment I'm using insertcoin with bricked kernel. And i have about 30% left at the end of the day. And I'm a fairly heavy user. So I find that to be acceptable.
And sorry if my spelling or grammer sucks, I'm from Denmark, so English is not my first language

Virtually everything that is asked on this board is a question. In fact, the majority of people who visit this board come to get a question answered. So the distinction is odd to me. People ask questions within threads that have declarative sentence titles all the time.
So if I had said "AHRD ROM gives insane battery life" then I guess it belongs in the general forum. Then if someone replies that Chameleon does even better as post #2, and I reply, why is it so much better as post #3. Then I have asked a question. My point is that in every thread there are questions, whether it's post #1 or post #3 seems like an arbitrary distinction. The fact that the Q&A section is not growing very quickly suggests confusion, since I still believe that if you analyzed the content of each post, and dare I say the overarching purpose of the board, is to ask questions. Newbies also see that he Q&A section isn't nearly as well frequented, so they post in the general section.
I think that the Q&A forum and the FAQ overlap in purpose. Anyway, just my 2 cents.
Thank you though for the answers to my question. I had expected, given the Anandtech review, that the One X would have comparable battery life to the iphone 4. However, I am finding this to be anything but the case, and I recently installed AHRD (wiped battery stats, etc). When trying to run down the battery (max brightness at 550 nits and surfing over 3g), I'm dead in 2 hours. My 2 yr-old iphone 4,with a peak brightness of about 500 nits, lasts approximately twice as long under identical conditions. I am finding the One X no better than the HTC Amaze, which has notoriously poor battery life. On the positive side, the One X's battery life is not as bad as the original EVO 4G, and the One X's standby battery drain is extremely low. I shudder to think what the battery life would be like if I had a US version which has LTE.
I have not noticed any improvements with any custom ROM thus far, but it's possible that using the screen at 75% brightness is basically such a determining factor that any gains in battery life are imperceptible to me. If someone can confirm that it is possible to drain the battery if you surfed at max brightness for 3 hours continuously and that that's just the state of phones today, then I can accept that. I just want to make sure that my phone is behaving normally and that any battery tweaks, cpu undervolting, wont' make a huge difference.

None of the custom ROMs change anything to do with battery consumption. A custom kernel could help, however I have tried them all and none of them make any appreciable difference.
Browsing over 3G seems to kill battery fast, I have never been able to get more than 3 hours screen time, and most of the time it is 2 or 2 and a half hours.
Hi thanks alot for the reply. I was thought that custom ROMs were supposed to improve battery life (one of the major reasons, if not the major reason, to install a custom ROM). In fact, in most of the intros for ROMs, they say something like "excellent battery life".
But you're saying that it is at the kernel level where improvements in battery life are made?
I agree with your conclusions--each custom ROM is about the same regarding battery life, and it is possible to surf and kill the phone in 3 hours of screen time, if I want my max brightness glory and over 3g.

[Q] New Nexus Owner, and introducing myself

Hello Everyone,
Many times while searching the internet for Nexus information, the search keeps having me come to this forum so I decided to become a member. Just got for my G-Nexus the other day, its replacing a Droid 3. Nothing really wrong with the Droid (well), but it was my first physical keyboard phone and I wasn't feeling it, and I heard so many good things about the Nexus I knew I had to have one.
I've had it less then a week now, and so far I love it. Though the one thing I must say I am not crazy about, which seems to be a common complaint, is the battery. It drains WAY too fast. Today though seemed more then ridiculous. I left my house @ 8:45 am @ 100% (right off the charger). Made some use of it on the bus, but nothing much (no calls, no video, no music). Already by 11:30am, I was @ 39%! I mean come on, I didn't even use it that much. Yes, I did notice I left the WiFi on, but it should not have drained that fast. Tuesday I used the device moderately and I was able to go home after having the device on for 9 hours and still have around 40% to spare. Its a shame they cannot make a battery that can accommodate such a great phone.
So some questions: Is it really necessary for me to root this thing to get its full potential? I never rooted a phone before. When I bought the phone, I got a shiny gel case that Verizon sells for like $20 - if I did get the extended battery and door, would this case still fit? I am thinking no. Is the ext. battery even worth getting?
I have more questions, but I will peruse the forums and see what everyone else is saying. So in all I just wanted to intro myself and say I am happy to be part of the forum!
Your battery should definitely not be draining this fast. Install better battery stats(look around XDA) and look at what partial wakelocks you have. Try to remember any recent apps that might have been causing the drain
The 2100mah battery will fit. If you're looking at the 3900mah extended batteries, those have their own custom backplates and won't fit.
I've read that the 2100mah battery adds about an hour of juice.

Sorry to sound dumb, but what do you by "battery stats"..?
And I am not sure what a wakelock is either - if you could explain
Hey,
I got my Galaxy Nexus this week too. This is my third full day of using and I get good 10+ hrs of usage each day. I use it a lot too. At least 2-3 hrs of talking, about 50+ texts, synching 4 emails, and browsing/streaming an hour or two each day.
You should check what drains your battery the most and go from there.

'better battery stats' is an app. go look for it. there's an XDA version
your phone goes into 'deep sleep' to conserve power. wake locks are when something refuses to let it get to that state and locks it awake. This is major cause of battery drain.
Better battery stats is available on the Play Store (ugh hate that name) but the dev is nice enough to give it to xda members for free:
http://forum.xda-developers.com/showthread.php?t=1179809
Aside from looking at wakelocks, go to Settings>Battery, then look at the list of stuff (in descending order) that's eating your battery. I went to watch a movie once at 90%, when it was done the battery was at 18% and I never even touched my phone. I checked that list and apparently Facebook killed the battery. Try and look for apps that might be using up a lot and either uninstall them, replace them, or trun off features that might be causing the drain

Root it?
It's a Nexus man. They're fantastic for root users.
All the roms are AOSP...
And bug free (or...mostly. AS bug free as any google build, generally).

I agree with you that the Nexus is fantastic for root, but it's not necessary for all users. I rooted mine because I was use to with my old HTC HD2, but ,except for changing rom, it's useless when you just get your phone.
I think that you can keep the stock rom, and don't root it. One day you will maybe need it, but the stock rom is very nice, it's enough to start (that's what I did with mine).
I noticed you are on Verizon, bad cell reception can chew your battery for lunch too.
There's something floating around in the development section (sprint I think) called battery mod.
Of course, youd need to root and unlock your device to get it working (takes all of about 5 minutes).
I also had this battery draining problem, but installing a custom from with a power saver governor and the battery mod, it'll drain 1% every 30min-1hour. Its essentially in "deep sleep", as the CPU winds down to 0mhz, instead of the standard 350. With this comes a lower CPU voltage, so less energy is wasted.
All in all, this is a great phone once you tame it.
Look for Black Ice ROM. Its probably one of the best here because it let's you choose a stock look or a custom look
