Thank you but it was just to see what others recommend. I've heard good things about the matrix kernel
[Nexus 4 Q&A, Help & Troubleshooting] zephiK:
Also when using those kernels download the app trickster mod it'll let you customize the kernel settings but don't touch anything you don't understand because you might mess something up. Franco and morfic have paid apps that customize their kernel but trickster is a free alternative until you commit to one kernel
[Nexus 4 Q&A, Help & Troubleshooting] alewis2k12:
Franco or Matrix...But while using Franco Ive seen a big difference in battery and thats just my experience with it but like the others say just try em out and see wats best for you my friend..
[Nexus 4 Q&A, Help & Troubleshooting] zephiK:
Agreed. Franco really knows what he's doing, no offense to the other developers. Morfic is another good developer.

Wasn't a huge fan of matrix on the Nexus S. Just my personal opinion (don't attack me because I prefer one kernel over another!)
[Nexus 4 Q&A, Help & Troubleshooting] alewis2k12:
+1 to that...
[Nexus 4 Q&A, Help & Troubleshooting] zephiK:
Nothing against math kid but (not saying he does this) but there are some shady developers or Rom cookers who say they added their secret special tweaks to boost speed or performance. I don't believe it because it's placebo. If there's no proof in the source then it doesn't exist.

Franco actually says what he did, and you can see it in the results. Plus he's very adamant about replying to feedback as long as it's not a silly question like "can I under volt using this kernel???" There's a reason why he has 20k thanks :p

But either way enough of my rant. Hope op finds a kernel he likes. I'd start using the most popular kernel out there and use it for a couple of days. If you aren't satisfied then try another. Satisfied but want to see if you can do better? Go ahead and try. They're all free anyways, the beauty of xda :)

Thank you for all your replies, I might give Franco's kernel ago. I'll be surprised if I get better battery life than I currently do on faux's because Franco's doesn't support undervolting
[Nexus 4 Q&A, Help & Troubleshooting] 19phil67:
I agree. I've tried both, they're efficient but I prefer the franco kernel
[Nexus 4 Q&A, Help & Troubleshooting] zephiK:
Franco doesn't support undervolting because,

I don't really undervolt my phone and have pretty good battery life as it is. I didn't undervolt on my Galaxy Nexus either because it had something called Smart Reflex undervolted for you when necessary. more info @ http://www.ti.com/dsp/docs/dspcontent.tsp?contentId=52746#a18

---- Franco isn't saying that there won't be UV support but as of right now he's focused on other things and will add it when it becomes more stable. And I agree with him on the second part about there are other parts of the kernel that can be worked on to have better battery life rather than just having people UV as the solution (for now).

Edit: there's a reason why his thread on GN has Views: 4,859,042 :P http://i128.photobucket.com/albums/p163/gbd270/views_zps2644eff7.jpg

I'm running franco Kernel on JellyBro (CM 10.1).

It seems to me that the biggest drain on the battery is when running on mobile data. If you can be on wifi most of the time you'll get great battery life. Otherwise I'm not sure if there's anything you can really do until Google comes out with a patch for those msm_hsic_wakelock issues.

[Nexus 4 Q&A, Help & Troubleshooting] zephiK:
kernels work on any rom. you dont have to worry about incompatibility unless there is a special case
[Nexus 4 Q&A, Help & Troubleshooting] bilguun1:
Try faux, having great battery life also great performance, I've tried every single kernel, kinda have an experience.
[Nexus 4 Q&A, Help & Troubleshooting] Sauveur:
Thanks everyone. Two more questions (I'm more experienced when it comes to ROMs, not so much with kernels): what will happen to the Franco kernel when the next OTA update rolls out? And secondly, what are the boot flash files? Do I need to worry about those or do I just flash the zip?
[Nexus 4 Q&A, Help & Troubleshooting] zephiK:
1. Well considering you're on stock ROM. You have a custom recovery, so you won't be able to accept the next OTA. Depending on what changes you made in /system/ (which if you're using Franco, it most likely did some changes there. Especially if you bought the Franco Kernel app, its changing values on your phone).

2. Boot flash files are if you choose to manually flash the kernel via Bootloader Mode in Fastboot. Just flash the zip in recovery as if you were flashing a ROM (no need to wipe)
[Nexus 4 Q&A, Help & Troubleshooting] Sauveur:
Well I downloaded Root Keeper which supposedly successfully keeps root on the Nexus 7 through an OTA update, but I haven't tried it yet on my Nexus 4. Where can I buy the Franco kernel? There are a couple different links it seems, one thread in the Galaxy Nexus forums and another in the Original Nexus 4 Development forums. Also does Franco work for Google?
[Nexus 4 Q&A, Help & Troubleshooting] zephiK:
https://play.google.com/store/apps/...t=W251bGwsMSwyLDEsImNvbS5mcmFuY28ua2VybmVsIl0.

Franco does not work for Google. The app linked above is cross compatible with Galaxy Nexus & Nexus 4 as well as other devices that he supports. I bought his app when I used the Galaxy Nexus, didn't have to pay again :)

A free alternative would be Trickster Mod (you can do the same settings as you would in Franco app) just cant update via app.
[Nexus 4 Q&A, Help & Troubleshooting] Sauveur:
Many thanks. What kind of difference do most people see in terms of screen on time? I can get 3 hours at best before it hits 0% (running stock everything).
[Nexus 4 Q&A, Help & Troubleshooting] zephiK:
Some people get 5-6 hours+ but im sure they either downclocked their processor or used 2G or something of that sort.

I think on average you can expect 3 - 4.5 hours of uptime usage without being BATTERY CRAZY. Battery crazy as those people who underclock their phones and all that, they do things to their phone to compromise their performance for a better battery life. For me, as long as it gets me through the day, it did it's job.

http://zephik.com/upload/Screenshot_2012-12-14-19-05-58.png was my best uptime (not even 0% yet)
[Nexus 4 Q&A, Help & Troubleshooting] Sauveur:
Wow that's crazy. What were you doing for those 3 hours? And the screen brightness?

Also does having CM as opposed to stock ROM make a difference in battery life?
[Nexus 4 Q&A, Help & Troubleshooting] zephiK:
I don't remember. It was awhile, Screen brightness is the same as what it is right now for me ~30%. I was probably just tweeting, XDAing, browsing websites. No games or videos or music.

It's kernel that has a more significant difference for battery life, not ROM. ROM is more for features. ROM helps very minimal (if any at all).
[Nexus 4 Q&A, Help & Troubleshooting] Sauveur:
So then here's the real question (which somewhat also applies to ROMs but can be more precisely applied to kernels): how can this guy Franco (who is by all means clearly very talented) do a better job than Google at making a kernel?
[Nexus 4 Q&A, Help & Troubleshooting] lazer155:
Did you try franco? If you did how did it compare to faux?
[Nexus 4 Q&A, Help & Troubleshooting] ceejay83:
On aokp, Franco felt a lot smoother than faux.
[Nexus 4 Q&A, Help & Troubleshooting] Sauveur:
So is Franco smoother and better in terms of battery life than stock kernel? How is that possible?
[Nexus 4 Q&A, Help & Troubleshooting] zephiK:
Is that sarcasm on how is it possible? Because it's based off the stock kernel and improvements are done to it....

That's like saying, How is that possible that the N4 is better than the GN? It's based off the GN.
[Nexus 4 Q&A, Help & Troubleshooting] dr.m0x:
I noticed little difference between the kernels. So long as I can under volt I will get a little more battery life but nothing significant.

If the processor must do something, it can do it quickly at high speed or slower at low speed. In the end it balances out, use more power but be on for shorter bursts or less power but run for longer bursts.
[Nexus 4 Q&A, Help & Troubleshooting] Sauveur:
I mean, how is it possible that some random guy can do a better job than Google?
[Nexus 4 Q&A, Help & Troubleshooting] zephiK:
He's not random...... anything is possible. The kernel is open source.

It all comes down to experience.
[Nexus 4 Q&A, Help & Troubleshooting] Sauveur:
Alright. Well I'll give it a go. Where is the stock kernel so I can reflash in case I want to go back?
[Nexus 4 Q&A, Help & Troubleshooting] lazer155:
Use faux's reset kernel: http://faux.androidro.ms/mako/mako_421_reset_kernel.zip or this: http://db.tt/8sKuWukX

Both are the same just from 2 different places.

They will give you the stock kernel back.

Alternatively you could extract it from the stock rom install download from google. The kernel is inside it.
[Nexus 4 Q&A, Help & Troubleshooting] zephiK:
download stock google images and you can fastboot boot.img if you want to go back to stock. or find a custom rom that uses stock kernel and take the boot.img from there.

or use franco kernel app to back up your stock kernel (boot.img)
[Nexus 4 Q&A, Help & Troubleshooting] djemgee:
I'm just going to say that since I've had my n4 (nov23) I've tried most of the popular ROMs with a select few kernels (trinity, franco, etc. But the best pair up for speed and ridiculous battery life is this latest code fire ROM + Franco #20 by far.

Anyways the devs just test and compile better code and find ways to basically mod the stock kernel or totally rebuild it to be more efficient as a kernel

I use Franco , and its improved my battery life considerably .

It's possible another kernel may provide better battery life, but I'm satisfied with battery life now.

I've been around xda for quite awhile and ran many devices on Franco's kernels,

I trust them to generally be just as stable as stock , and stability is just as important to me as battery life.

I think too many devs try a kitchen sink approach to kernels , they throw in every feature they read about without really testing to mods individually to see if they help.

I like that Franco keeps his kernels lean.

[Sprint Samsung Galaxy S III] procter:
So I'm playing with the brand new Sprint S3 with LJ7 stock rom and is stuck at the very first step. Managed to get the COM port opened in the PC for Samsung USB diag mode, however, the DFS 4.0.2 and QPST failed to connect. I can choose the right port to open in DFS, but whenever I try to read from the phone, it shows researching device forever, and I'm certain the spc code is correct (got from the app getmymsl, and I could use it to edit the data file). In QPST, there is no device listed under that COM port (normally you should see the phone listed as SURF****)

Searched and followed this instruction: http://xdaforums.com/show...7&postcount=14 but still not working for me.

Just now I tried install the samsung usb driver and DFS 4.0.2 in a freshly installed windows 7 (64bit) machine, so the only COM ports installed/opened are the samsung's, but still the same symptoms.

I've heard people talking about downgrade ROM and radio for those software to work, but I also saw people directly using DFS for the newer ROM. What did I do wrong then? Please help.
[Sprint Samsung Galaxy S III] procter:
BTW, I dial ##3424# to bring out the diag mode panel, and tried different combinations such as:

Modem / dm+modem+adb

PDA / dm+modem+adb

pda/ rmnet+DM+modem

all gave me the same issue: having the COM port opened but the device could not be recognized.

However the phone was recognized fine as a media device.
[Sprint Samsung Galaxy S III] bofan.cabrera:
Try doing a factory reset. I find that after you flash the phone once using ##DIAG#, you won't be able to flash it a second time after the firmware upgraded. That's just been my experience though. You would still be able to see the port, but it won't read/write. Instead use *#PATH# instead.

In addition to my brand new GN2 I have a GN10.1. Since I picked up my GN2 yesterday I havent touched my 10.1.

Of course the 10.1 is better for taking notes based upon the sheer size, I find myself getting better at writing on the GN2. Seemed so tiny at first but not so much anymore. I might eventually get pretty quick at it. Also never liked swype before but it is so accurate doing spell checking on this that it is growing on me. Wish the typing spell checking worked as well.

So we will see. If I keep getting better at this I may end up selling the 10.1.
