Sprint Galaxy Nexus LTE Performance

Newbie question. Sorry in advance.
I've tested my device on ICS and JB and still find that it is underperforming. What is the cause and what can I do to increase the performance?
I assume that flashing a kernel will help but I'm really really not sure if it would work with the ROM I'm using. Also how would I go back to the previous kernel?
Many thanks for any tips.

Well there are few things you should ask yourself, Are you using a stock kernel? first step is to flash your device back to stock then re run the test. if its still underperforming, then it could be a defective device or it could be those numbers are off, now ask yourself is the device laggy or do you feel like it isnt working well. note that for some reason live wallpapers don't like ice cream sandwich particularly on the nexus device.
if the answer is yes even with a barebone stock rom then it could be the phone. to answer your second question, its best to backup your rom prior to flashing a new kernel so that you an restore it if needed later. also id recommend the franco kernel, its very lean but it really helps boost performance. hope that helps.

Thank you so much for your reply! Yes the performance on stock is pretty much the same (benchmark-wise). The phibe felt a but laggy in ICS but with JB it is very smooth.
I'll try the Franco kernel to see if it helps
Thanks again for your advice.

I'm still on rooted stock rom and I'm really happy with battery life. I think its more to do with the kernel.... there's Perseus kernel which has undervolt features in the Original Android Dev forum which might be of interest to you... couple that with Rom cleaner and you're good .... good luck

[Q] Question about Leankernal+Paranoid Android

Hi!
This is my first post on the xda Forums; I've just been a lurker for a while now. I am still learning the ins/outs of Smartphone modifications/rooting/roms etc, so forgive my noobyness.
I've recently (two days ago) Rooted my Rogers S3, and Flashed Paranoid Android 2.55 Onto it. I'm loving it! However The battery life is something I'm not too keen on, so I've been lurking google for hours upon hours, forums etc, and I'm seeing that a popular Kernal people are using to cut down on battery drainage + Smoothen things up, is LeanKernal.
+
Now, I've poked around quite a bit, and I've read through something like 75+ pages of this topic: http://forum.xda-developers.com/showthread.php?t=1845836
But just for the sake of not Bricking my phone / Digging a hole I'm not educated enough to get myself out of; I'd like to ask:
Is LeanKernal what I am looking for/compatible with, my P.A flashed Rogers S3?
Or any other tips for me?
Much appreciated!

Lean kernel is compatible with AOSP ROMs. The developer should have a clearly-marked download link.
That being said - if you can't find the answer you're looking for by yourself, don't flash it. It's very easy to brick a device by making one small mistake.

Lean kernel is designed for aosp ROMs but the new ones are based on a different Linux version. If you install paranoid android 2.55 with the newest lean kernel it will never boot. You need to either find am older lean kernel or flash the newest paranoidandroid.

I read people were using lean kernel 1.6 for paranoid android. I'm more than willing to try another compatible kernel if anyone has suggestions for a smooth one that can help with battery life extension

All the kernels get updated frequently. I'm using the Paranoidandroid 3.15beta and Tasks latest Underwear kernel and it's working fantastic.
Battery life if device, app and user specific so you'll have to just experiment.

that's why I am asking for a recomendation based on what I'm currently using. rather than reflash a different ROM for the time being I'd like to find a kernal to use with what I have

Edit.....
I don't think you can use that one. It's for 4.2 not 4.1

Go to settings > about phone. If android version is 4.1.2 use this. http://www.mediafire.com/?99f7dn0gya0bb20
This is the latest ktoonz kernel for 4.1.2

Awesome. Ktoonz was another I had been looking into, and heard good things about; so thank you very much for your help Korguy123. It's appreciated, and sorry for my noobyness XD I'm working on Levelling up so to speak haha.

Don't apologize. We all start somewhere. When I get off work I'll look into which lean kernel you can use. Give ktoonz a couple charge cycles to see how it's working before you start tweaking any of the performance settings.

[Q] Cm11 over clock?

Hi,
Is there a way to overlook cm11? So far I can't find a compatible kernel. If there is a way then some help would be appreciated. =)
I am doing a presention on how to improve android performance and this would be great to show to the class.
Thanks

Kt747 kernel supports over and under clocking.

Really there are none. There is shift and devil (dual boot kernels) but they don't work that great.

Bah, thanks anyway. I only wanted one so I could test smartass v2 with stock 4.4 xD
