I get more than 4 hours display with stock kernel and overclocked GPU. 17 hours on battery. Played some supper Nintendo, Nintendo, listened to music almost 2 hours and the rest wifi browsing. Ended with 17/4 20% left. Got over 5 hours last weekend. My goal is 6 hours display but that is going to be tough using the phone.

Good job. Idk how long mine will last now. I did have it the Android OS bug though with these results from bigxie 7.0 kernel and I backed it up and flashed a new one.. but this isn't really a bragging right thing, the point is we both can get through the whole day easily no matter what we do.
[Samsung Galaxy Nexus] aohus:
are you on gsm version though? on rooted stock (LTE version) i get about 2 hours of on-screen time 4G all day and thats about it.
[Samsung Galaxy Nexus] @rbiter:
Yes. GSM. Verizon's shady tactics and juice sucking lte are no no's for me. Not many people are getting great display times unless LTE is turned off.

Initially I had to charge my GN at least twice a day but I downloaded Set CPU, Ultimate Battery Juice and the Extended Controls beta battery helper and I am now very impressed indeed. Trying out the Android Revolution HD ROM too, time shall tell
[Samsung Galaxy Nexus] KWKSLVR:
Uuuummmm, ok, I'll bite. How the heck is a bootloader going to increase battery life? That makes no sense. ;)

To the OP, I was on stock 4.0.2 and flashed Android Revolution HD. The battery life is a little better, and can probably be accounted for by the placebo effect, but it's a smoother/quicker experience than the stock 4.0.2 ROM. It also looks completely stock, so if that's not what you're after, that might be a turn off.

Every 4.0.3 ROM I've tried has horrendous battery life and insane CPU Awake times (stuff like CPU Total: 37 minutes; CPU Awake: 5 hours :eek: ), something that I have not experienced on 4.0.1 or 4.0.2.

I typically get battery life like you. In great reception areas I usually get 14-20 hours of battery life depending on whether or not I'm using the stock or the extended battery. I'm also not glued to my device 24/7 since I have to do stuff like work (apparently most of XDA watches movies and plays games all day and gets angry over 6 hour battery cycles). Coming from a Galaxy S and not being a native whiner, I know what these screens can do to battery life, and the GN is extremely impressive on battery life. People whine and complain, but this is a phone with .65" of more screen and over twice the hardware of the Galaxy S, along with only about 30% more battery and I was lucky to get my stock Vibrant to make it 10 hours. :eek:

Without disconnecting from the data network or using Juice Defender (which to me defeats the purpose of having a smart phone), I really think that what we're getting is probably the best battery life possible right now.

You have any other ideas? No you don't. Would updating the bootloader cause anything harmful? not really. I'm not sure if this is the case but it's a step towards resolving the problem by telling users to update their bootloaders if the newer version isn't going to change anything (and it doesn't really change anything except things behind the scene which you won't even know what Google did).

This is the latest bootloader coming from Google that comes with 4.0.3. There is a reason why the bootloader was updated.
[Samsung Galaxy Nexus] @rbiter:
That really didn't tell anything. Not jumping you, Mr. Negri, lol, but we need a better explanation than that. I am going to assume kwkslvr wants the same. I am also guessing he's experimented and decided 4.0.2 was along the lines of "if it ain't broke don't fix it." which is where I'm at. 4.0.2 has some hiccups but it's very stable and great on battery. I am sure some more "stable" battery improvements will be made in the future, but I'm going to have give samsung some props for the hardware engineering. They even outdid the gs2 in power efficiency out of the box.

ARHD + James Bond 1.35 OC UV did the trick for me.
[Samsung Galaxy Nexus] zephiK:
Well for all I can say in my own personal experience including others. The updated bootloader has helped. You can believe me if you want, or disbelieve me. I really don't care, I'm just simply handing out suggestions, if you don't like it then just ignore me and stop trying to harass me about "negri" and "bootloaders."

It's not like updating the bootloader will do any harm, there's a reason why that updated bootloader came with the 4.0.3 update and for the fact that Google recommended using that bootloader (regardless if you're on 4.0.2 or 4.0.1). Regardless if it is for battery fixes or something else, it is most likely to make the overall performance of the Galaxy Nexus better.

And for that term "if it aint broke, dont fix it." That's like saying, mobile phones weren't really broken when they were just used for making phone calls. Now they're used as devices to browse the web, check emails, and do all sorts of other things.
[Samsung Galaxy Nexus] adrynalyne:
The bootloader was updated to fix fastboot lockups under certain circumstances. As a developer, I was frustrated when rebooting to the bootloader would lock up at times when in GNU/Linux. The new bootloader fixed it so that I could use fastboot without it ever hardlocking. Before that, I had to unplug the device, put it in fastboot mode from the device, and then plug the usb cable back in to make sure I didn't lock up.

Once the bootloader hands off and the phone starts booting, it has NO effect on battery whatsoever. It isn't running, either.
[Samsung Galaxy Nexus] adrynalyne:
It was leaked. It didn't come with any 4.0.3 update ;)

Can flashing a bootloader hurt you? Yeah it can if it goes wrong.
[Samsung Galaxy Nexus] zephiK:
Flashing anything in Android can go wrong. That's no one's fault but the flasher, and with the package I linked... all you do is double click a .bat file in Windows while your phone is in bootloader mode. If that step is too difficult then, I don't really know what to say because it can't get any easier than that.

And that could be the same bootloader that comes with 4.0.3 when it is fully released.

It is the newest and latest bootloader coming from Google/Samsung due to the lettering, KL01.
[Samsung Galaxy Nexus] adrynalyne:
Flashing a rom that goes wrong can hurt you, yes.

Flashing a bootloader that goes wrong, CAN BRICK YOU.

Nothing is foolproof. So I wouldn't be one to casually flash radios or bootloaders. I've been playing this game for many devices, and have seen many bricks. Trust me, its possible.
[Samsung Galaxy Nexus] zephiK:
And you're talking to me like if I'm new to Android myself? I've been using Android since it's first came out since the G1 days when you had to root through terminal emulator and spend 20+ minutes to root.

Stop trying to scare people flashing things through fastboot and/or Odin. No one can make their own radios or bootloaders, they have to come through Google (or a manufacturer based on which device) directly.

People including myself experiment with various radios and alternate them to go through a series of tests to validate which one is better for their network and location overally improving their signals, battery life (poorer signal = less battery life because your phone has to deal more power to getting service), and so forth. This is why MD5 hashes are included and users have to verify its MD5 hash because if the MD5 is wrong, it will cause problems. I agree with you on this but everything that a person does to their phone is the person's responsibility. No body else.

You're also speaking on the behalf that I'm forcing people to update their bootloaders. When people are updating their phones via OTA. Behind the scenes, this is also updating their bootloader, kernel, radio all for them. Fastbooting it is simply doing it manually rather than a flashable zip.

Are you trying to imply that updating your phone via OTA will also cause bricks because it will update their bootloaders/radios?

Also, this is starting to get irrelevant to the OP's post about kernels and ROMs. So if you wish to continue this conversation, feel free to inbox me. Until then, I will stop right here because this argument is taking over the OP's request on user feedback on best rom/kernel combo for battery life.
[Samsung Galaxy Nexus] adrynalyne:
You are delusional.

I never said you forced anyone to do anything.

The only things I did say were:

The bootloader has nothing to do with the battery. Learn about how things work before spouting nonsense.

Casually flashing bootloaders is not a good idea.

At least when its OTA, its under warranty if something goes wrong. You may not be new to Android, but you are clearly new on understanding how a device with Android works.
[Samsung Galaxy Nexus] @rbiter:
I guess you can't see it and it is why you're getting defensive and long winded. You still haven't given any explanation for the bootloader. From my experience, I get better battery life with the screen off. Ever since I've owned a phone period. And I don't need to explain that. But people with a bug will disagree. You keep preaching how this bootloader is going to be the Holy grail of battery life and when it comes time to explain, you digress. So come with it. Or shut it down.

[Samsung Galaxy Nexus] ScooterG:
Sooo....

The best ROM for me so far has been AOKP with Imoseyon's kernel. Very minimal drain while idle. I haven't tried AOKP with Franco's yet. Although Franco with Bugless Beast was a great battery combo as well.
[Samsung Galaxy Nexus] bigrbob:
Thanks for getting back on subject, while those 2 guys tuck 'em back in.
[Samsung Galaxy Nexus] aohus:
i'm wary of the custom ROMs and custom Kernels. (fyi i have flashed almost all existing ROMs for CDMA Nexus previously before going back to stock)

fact is, many of these custom ROMs and kernels are tested a couple days max and released. nearly not enough to release something thats stable, whereas Google developers go through a much more rigorous process.

i used to use custom ROMs all the time(droidx days + gnexus now), but I found out that stock gives me best battery life.

clearly, OC'ing your CPU/GPU + UI/memory tweaks to improve performance will always give worst battery life, which is what 99% of the current ROMs are tailored for.

i'm not the type that relies on a charger sitting next to my mobile device. A mobile device is what it should be, a mobile device.
[Samsung Galaxy Nexus] luffyp:

Overall... a updated bootloader will resolve issues that people may encounter with their phones. Google never releases any "changelogs" for their bootloaders. It's just there to be updated with no patch notes whatsoever. But in the end, Google have undergo many tests with the bootloader.

Coincidentally, you may encounter a problem with flashing a ROM and wonder what the problem might be. At that point of debugging, you wouldn't even realize that you were using an outdated bootloader. But if you actually listened to me and updated it without bringing so many questions on why you should update a bootloader then you wouldn't be having that problem. Visit that thread, that's a guy personal experience. If you wish to hijack his thread and falsify what he said, then go ahead.

For myself, I stand to my point that updated bootloader has the possibility of resolving some of the problems that these users are experiencing when it comes to battery life or just stability in general. And since either of you haven't PM'd me to continue this conversation, I will just end right there.
[Samsung Galaxy Nexus] aohus:
afaik, with the limited amount of android literature i've read the bootloader, kernel, and OS itself can all affect battery life.
[Samsung Galaxy Nexus] Stadsport:
The bootloader has no affect on battery life. Baseband? Sure, but like someone mentioned earlier in this thread, a bootloader providing better battery life would be like a starter giving your car better mileage.

New bootloader:

Difference of 10 minutes. I'll chock that up to using the phone slightly differently through the two cycles. Saying "the battery seems like its lasting longer" is a placebo effect.

Best ROM/Kernel Combo for Battery Life

HeyItsLou's Redemption ROM v1.0.3 with Franco.Kernel#12 has the best battery life I have come across. Better than gummynex / aokp / revolution with stock and custom kernel. Amazing use times and standby times. Franco UVd just enough to have improved battery life without sacrificing performance. Redemption rom looks almost completely like stock, Lou wanted to preserve the ICS look, totally in agreement with him. He optimized all animations and improved launcher and auto rotate speed. No lag whatsoever. Everything is snappy and smooth. Best combination I have had on GN. They are both only continuing to get better.

My ROM

I am a new Galaxy Nexus owner as of last Friday, and I'm currently rolling the Android Revolution HD 2.1.2 ROM by mike1986. So far I'm very satisfied with the battery life that his optimizations have provided. To this point I've been able to get about 30 hours out of a single charge on regular usage with Wi-fi being the primary data network at home.

GPS seems to be murderous on the battery (I gained an extra 6-7 hours of life after turning off GPS-sat acquisition), and I've read in several places that LTE isn't so kind either. I won't know that until a little later today as I'm now at work and have to rely on LTE; there are no Wi-fi networks here.

Otherwise though, a combination of this ROM and some slightly conservative settings when using apps seems to result in respectable battery life.
[Samsung Galaxy Nexus] reuthermonkey:
Unless you have a runaway app that's forcing your GPS to stay active, disabling/enabling GPS should have no effect on your battery life. The GPS toggle doesn't activate GPS, it just allows it to be used for location service when explicitly called by an app. The only way that you'll save 6 hours by disabling GPS is if you have an app that's not playing nicely.

As for LTE, yes it will drain your battery. LTE phones need more power for SC-FDMA transmit on the uplink than WCDMA needs, plus it's an extra radio for your battery to power, which is a bit of a double-whammy. Disabling LTE will certainly save your battery, but of course at the cost of being stuck back on EvDO.

Currently trying Android Revolution HD 10.0 on my GSM Galaxy Nexus. I'll provide feedback in a few days. Today's my first full day run with this ROM.
[Samsung Galaxy Nexus] haidoz:
Stock 4.1.2 with Trinity kernel was my best setup for the longest 22 hours of my Gnex and 4 hours of screen time.

Currently faving AOKP based ROMs for their features though.. Vanilla Rootbox with it's default Lean kernel could last me 16 hours life and 3 hours screen. Just enough for my daily basis.

So basically what has happened is I have flashed my phone back to stock firmware from here (http://xdaforums.com/showthread.php?t=1012938&highlight=2+1+1+a+0+6) (because I bricked it, and now it no longer lets me connect to the Network(Telecom XT NZ))

Why does it not let me connect to the network anymore. Other Networks still do work though (2Degrees, Vodafone).

Is there a way to fix this(unlock, without having to pay)?

And also if I was to do the code thing, could I install custom firmware (eg. MiniCM7) and then use codes?

EDIT:

It seems that the phone can simply no longer connect to 850mhz frequencys (which is what XT use). XT also use 2100mhz which I can connect to but is very limited.

I don't know if this means it is locked. But the XT sim card does work in some places where the 2100mhz frequency broadcasts. So maybe not a SIM lock.

Exactly what it says at the moment is "No service. Selected Network (Telecom NZ) unavailble"

The phone I think should still work somehow shouldn't it since it was already unlocked when bought and after flashing the firmware it no longer does.

EDIT 2:

After reading this:

http://www.ben.geek.nz/2009/06/a-question-which-phones-can-i-use-on-xt-and-vodafone/

Somehow I have changed the phone from a 850/2100 phone to a 900/2100 all through a flash of a UK Firmware 2.1.1.A.0.6. If this is true, then should I be able to find a firmware to flash it back to 850/2100 phone?

EDIT 3:

Starting to figure this out.

My idea is the phone was originally a U20a and I flashed a U20i firmware !!

Downloading U20a firmware now.. I think this should work !

EDIT 4:

Using the AUS U20a firmware from..

Original tutorial found here http://www.htcmania.com/showthread.php?t=310924

This is a rough translation and I haven't tested it yet. Use at your own discretion.

If someone could natively translate this I'd appreciate it.

Prerequisites:

Root access/SDE Enabled

3.2.78 EXT4 Rom NOT SQUASHFS

Root Explorer (Maybe ES File Manager could work also?)

Chainfire 3D

Plugins for Chainfire 3D

Open root explorer, go to the folder /system/app and look for the application: GravitronLWP.apk

Move it to the storage folder or the root of the sdcard and exit.

If you haven't already, open the market.

Download and install Chainfire 3D.

https://market.android.com/details?id=eu.chainfire.cf3d

Open the Chainfire 3D. It will request Root Access, checkmark the box to always accept and hit accept.

Go to first screen of the application:

Once on this screen click on "CF3D driver"

On the next screen click on "Install".

The application will warn that will begin to install and then it will reboot.

Pressing accept again "Install"

We'll see how to execute some commands and restart the terminal

Once you have restarted the terminal, you have to download plugins from a pc from this link http://www.mediafire.com/?jmyx1mldkfwn11o

We will see that we have downloaded a compressed file. Now click the right mouse button and unzip it on your PC

3 appear. Zip files, which are the need

We connect the tablet to the PC via USB

We spent the 3 files. Zip we have unzipped to the internal SD

It is important that they are at the root of the SD, and not in any folder

Once past the files, disconnect the USB tablet

Now we return to the application Chainfire3D. We opened it again

We will see that on the main screen, at the bottom it says "Install plugins / shaders". Press there.

Just make a file read and take us to the next screen

Now we are pressing on each of the 3. Zip files that are in the "Install plugins and shaders"

When we go giving one to one, without running and slowly, we agree on "OK" after uploading files.

Once complete return to the previous screen with the "back"

We return to the home screen

Where it says "Default OpenGL setting" press

Appear in a new screen

Where it says "Use Plugin" select and open the NEXT screen:

Now you can choose which plugin you want to use for each game, either Nvidia Tegra 2, Qualcomm or PowerVR.

Once selected, leave the application and restart the tablet for safety.

You are now ready to use whatever game you want on your tablet. Enjoy!

Failure to do this correctly may or may not result in a bootloop. Worst case scenario, you'd have to reflash.

Help for those having trouble installing plugins!

I have successfully rooted my Archos 80 G9 to 3.2.79 (thanks, @surdu_petru, @letima and all who contributed!), and I was able to install Chainfire3D and driver, but the Chainfire3D app would not see the plugins. I tried placing them at root ( "/" ) and on the sdcard root ( "/mnt/sdcard" ) and rebooting the device several times, but each time Chainfire3D comes back with "No files found!"

After several hours of frustration and lost productivity, I carefully watched the list of folders being scanned as it flashed by and noticed that one of the folders being scanned was TitaniumBackup. So I copied the plugin files to the TitaniumBackup folder:

adb push libGLEMU_NVIDIA.zip /data/media/TitaniumBackup
adb push libGLEMU_POWERVR.zip /data/media/TitaniumBackup
adb push libGLEMU_QUALCOMM.zip /data/media/TitaniumBackup

I ran the "Install Plugins" step again, et voila! Plugins galore!!!

Hope this helps someone else in their quest for Chainfire3D glory!
