That's average if you're on CDMA. Read thru the thread.

On stick battery, I was getting 3 and a half hours and was on par with getting 5 hours if I just kept letting my phone drain. Best I've ever seen and I was streaming YouTube and Netflix. I was using Franco's stable kernel on Codename Android. I set my powermode to power save and that was it.

Google now adds a lot of battery usage. If you trim this down a little on the type of things it should monitor, and especially the Google Maps location services, it shouldn't be far from ICS.

[Samsung Galaxy Nexus] Hero_Guy:
It didn't affect it much. When I set it to powersave mode, it set my governor to lazy. It was ok but there was a very slight sluggish feel when I would turn on the device. The only way I noticed it was when I was texting and it would lag slightly. Since then I switched it to interactive to buff up performance a bit. My max/ min is 729/230. I'm still playing around with Franco's app but overall this setup is solid for my phone. Sorry for the late reply

---------- Post added at 11:16 PM ---------- Previous post was at 11:12 PM ----------

If you use Franco's kernel and download his app in the play store (about $3) it allows you to tweak the kernel and there's an option to set power modes. He has pre-set ones or you can create one. I'm using his powersave mode and it set my governor to lazy and my min/max is 729/230. I'm still messing around with it but I went from having an hour and a half on screen time to 3 1/2 hours with about 35%-40% left. Also my phone used to run really hot but now it's nice and cool.

Looks like your device was on and awake mostly at the end. Screen on week decrease the battery very fast.

Yes, but it goes down slower when I have the screen on, but while on, lets say, 60%... In the end, it just flies away... The battery.

I usually get around 2 hours with the regular battery. But ever since I got the Hyperion 3800mAH one, I've been getting around 4 hours, but the screen has been getting very hot, around 115 degrees.

[Samsung Galaxy Nexus] mironiko:
So, nobody more with the latest 30% draining faster than the rest? I would love to somehow solve that...
[Samsung Galaxy Nexus] bgdxv:
Mine drains faster between 29 and 19. I think it's normal, it's an error caused by the fuel gauge in battery, which isn't exactly the best one

[Samsung Galaxy Nexus] whitedragonz83:
I replied, saying you had the screen on a lot the last 30% , that increased your battery usage.
[Samsung Galaxy Nexus] bgdxv:
Nope it's not that. I get this thing too between 29% and 19% and i'm sure that every battery has a zone where it decreases faster, you just need to be extra careful in order to find it
[Samsung Galaxy Nexus] mironiko:
And I told you that it was still to fast, 'cause it doesn't go down that fast with screen on and battery above 30%.

Would reflashing help? Or wiping the battery stats from CWM?
[Samsung Galaxy Nexus] whitedragonz83:
Show a case where the device is less awake and less screen on time like the rest of your graph was, otherwise the current shot doesn't prove anything except you used it heavier at the end.

I will try to post my battery drain tomorrow when it is best out just in case I see the heavier drain at the end also.

I m also having similiar issue ,my battery drain quickly after 20% ,it drain like hell even if phone is idle ,i think its something to do wid battery stats.

This screenshot shows the situation
[Samsung Galaxy Nexus] bgdxv:
Yes, I'm pretty sure it's an issue with all the Gnex, caused by the fuel gauge in the battery. Pretty common issue across the android platform. Somehow, apple managed to eliminate this problem and their iphone fuel gauge is pretty damn accurate. I think this is the main reason why on the iphone you can enable the battery percentage to show in the status bar, but android doesn't have this yet - so the issue is harder to notice :(

[Nexus 7 General] Krunk_Kracker:
Noticed none of the current builds have the CRT animation enabled, thought I'd share how to turn it on. Please note that it is at times a bit buggy. For me it works about 8 out of 10 times.

What it is:

[YOUTUBE]_zFwpb_LDHQ[/YOUTUBE]​

Note: 1 - This will work on any device and on any version of Android back to GB. (Obviously the Nexus specific tools wont work on anything other than the Nexus)

Note 2 - You will have to redo this every time you update your rom.

Here's the quick rundown -

First, you'll have to pull the framework-res.apk from your tablet.

This can be done via adb, but the easiest way would be to either use WugFresh's Nexus Root Toolkit or mskips Google Nexus 7 TOOLKIT.

When asked what file to pull, type in "/system/framework/framework-res.apk" (without quotes)

Once you have that pulled, install this tool: http://xdaforums.com/showthread.php?t=1432152

Follow the directions on how to use it in the thread.

Once you have decompiled the apk, you'll want to edit the "files-to-edit\framework-res.apk\res\values\bools.xml" file.

The value you want to change in the bools value is the "<bool name="config_animateScreenLights">true</bool>" change "true" to "false". I reccommend downloading Notepad++ to edit.

Make sure you save it. Once saved, recompile the apk using the tool you install, then create an update zip (I renamed mine to crtanimation.zip for ease).

Reboot into recovery, flash the zip, clear cache, reboot.

Tada!

[Nexus 7 General] krelvinaz:
They most likely don't know what CRT animation is, NOT why they might want to make changes to the system.

Nothing in the OP provides a hint as to what that is or what it does. To be honest, I'm not sure I know what it is. A quick search shows that it is enabled in a lot of ROMs but not what it actually is or does.

OK, makes sense, I was assuming most knew what it meant.

[Nexus 7 General] NotablyNice:
If you don't know what it is then you obviously haven't flashed many roms and therefore should probably not even attempt this...

Thanks OP and sry for the ungrateful ones here.
[Nexus 7 General] Krunk_Kracker:
updated OP with a demo vid

I guess the CRT animation is more obscure than I thought.
[Nexus 7 General] krelvinaz:
Okay... I get it... It enables animation effects when turning the device off, rather than just blanking the screen.

I get the same effect turning on and off with

https://play.google.com/store/apps/details?id=com.soulfulz.android.turnoffscreen

You can select from a number of effects, sounds for both when the device is turned on and off via the button. You have to hit the button for it to do it, but for the risk of modifying system files, this is easy and safe to do.
[Nexus 7 General] NotablyNice:
Except your solution is wakelock city on top of having to enable it as a device administrator. Sounds like you also have to hit the shortcut or use the app itself to get the desired effect versus it being naturally accomplished when hitting the power button/screen timeout. And if it doesn't work in ICS, not sure it will work on JB.
[Nexus 7 General] Krunk_Kracker:
My way is easy and safe to do, if you follow the direction.

All your doing is turning something on. It's something that Google intended to be toggled.
[Nexus 7 General] krelvinaz:
Something users of XDA are so good at doing? Reading and following instructions.

Curious, they didn't implement it in their flagship first tablet and first official device to have Jelly Bean?

BTW, I am not knocking you, just have a lot of experience dealing with users that don't read, can't follow instructions...

The info on extracting and the tool was good reading, I just know a lot of users that will botch this up and start posting BRICKED threads.

[Nexus 7 General] Krunk_Kracker:
I'm sorry if people are unable to follow direction, but honestly that's not my problem.

If they mess it up, it wont brick, and if it does, all they have to do is dirty flash their rom and it's fixed.
[Nexus 7 General] Guardsix:
I asked the question "Why" because it seems a lot of trouble just to see your device (N7, in this case) turn off. I've done a great deal of modding to my ICS devices, but haven't really found much reason to mod a JB device. I know there are tons of boot animations which make your device really different when turned on, but having CRT just for turning off your device seems a waste of time.

Of course, this is only my opinion and I'm glad you figured out how to do this, but I still don't understand why!
[Nexus 7 General] Krunk_Kracker:
Why not?

To sound cliche, Android is all about options.

[Nexus 7 General] osm0sis:
Probably very dumb question but hopefully someone will help me since it has never been explicitly stated in this thread... this mod is for deodexed only right?

I'm looking in framework-res.apk from stock jro03d and I don't see a /res/values/bools.xml or even a /res/values/ folder at all.

Edit: NM. I now understand the difference between decompiling and extracting! Having errors on recompile though.. it's the echo off error others were having.

Checked and the log is full of "invalid resource directory name: G:\FF\files-to-edit\framework-res.apk\res/anim-sw720dp" etc etc.

Edit 2: Just used APK Multi-Tool instead. I know it worked since the other bools.xml mods I made were effective, but for some reason the CRT animation only showed maybe once since I enabled it, and hasn't since. Maybe this is why it's disabled by default? It just doesn't work 100% on the hardware.

Not working

I think I stumbled upon a potential solution for some of the compiling issues people were having (at least it seems to have worked for me in a very minor way). The aapt.exe and apktools.jar files in the resources directory of the Framework Flasher tool seem to be the cause of the issues. I updated them by downloading iBotPeaches' newer versions at http://connortumbleson.com/apktool-v1-4-5-a-tool-for-reverse-engineering-apk-files/

After replacing the old ones with the newer ones, it compiled for me. I then created my zip to flash. No dice. It booted up fine, said it was updating the apps, then dropped to the X screen and stuck there.

I pulled up a Nandroid and rebooted. I decided to start from scratch. Pulled the framework-res.apk, decompiled, edited bools, recompiled, signed, zipped, reflashed, and cleared dalvik/cache.

And son... of... a... Back to the bootloop. I can't figure out what I'm doing wrong.

change jre6 to jre7 if you're using java 7 (check the folder and path ofc)
