Purity ROM + which kernel? - Nexus 4 Q&A, Help & Troubleshooting

Hey guys. I'm looking to flash a kernel on my Nexus 4, 4.4.2 Purity ROM. It's my first kernel ever and I'm looking to get better battery life. I don't play much games, I mostly listen to music, watch YouTube, do Facebook, browse the Internet and similar.
So i guess the most important thing is battery life. If you guys have any suggestions, please let me know, I have no idea how to find one myself.
Thanks!

You can start with Hell Kernel :good:

Which ever fits your needs. There is no best or worst kernel. Try them out and decide for yourself

You have to experiment the kernels on your own and find which one is right for your needs. Everyone will have a subjective choice as to what is better for their daily needs.

Kernels are personal choice, try some and check for yourself. Personally I prefer Franco kernel.

I would try Matr1x. You can get really low UV values (-87.5mv, 192mhz > 662500uvolts), tweakable screen color with support for profiles, and 192 mhz support.

Purity + Franco gives great battery and performance!

Best Kernel for Paranoid Android

Just curious. I have about decided that Paranoid Android is going to be my rom of choice for my Nexus 7. Looking to see what kernel everyone is running and which one they think is best.
I've been using trinity for a few days with that paranoid and it has been working brilliantly, the battery life is excellent, very quick, and any instability I can definitely credit towards my inexperienced tinkering

You can use the Franco Kernel, or otherwise (my favourite) Faux ES Kernel!
Careful with faux123 014b1/014b1es kernels

I also love faux123 kernels, especially 013m (or 013es if battery life is an issue). USB OTG charging works if enabled in FauxClock, very stable.However, 014b1/b1es freezes if Bluetooth is enabled and BT device connects.
Hope it helps.
Running M-Kernel - a29 here. Been trying out a few for the past couple days. Best advice I can give you: play with each one for a while and makes some notes of how your device feels with each kernel.

[Q] (Q) Reccomend rom and kernel combo?

Hi you guys, I just got my nexus 4 a week ago and rooted it right away.
I have been looking through the list of roms and I honestly don't know which is right for me.
I'm looking for a STABLE rom that knows how to balance battery life and power.
I don't care too much for customization, just a little would be nice (Nothing too overbearing).
It would be if the rom just knew what it was doing, and doesn't need me to constantly tweak things.
SO in all, just the BEST reccomnded rom and kernal combo.
Thank you in advance.
EDIT: I am currently running the stock rom, and franco r53 kernel
Slimbean. Stable, no bugs. As for kernels, they all are good. I like trinity and matrix
You will get a lot of different feedback what is the best. In the end it's a matter of taste.
atm I like AOKP with faux123 kernel. I heard the Minco Rom which comes with franco kernel should be very stable and smooth. And this rom and kernel where developed and supposed to work together:
"Welcome to the cross collaboration between myself & Francisco Franco.
We're proud to announce the first and ONLY Franco supported ROM. This ROM has been built from AOSP Jelly Bean."
http://forum.xda-developers.com/showthread.php?t=2061573
I don't know if you already know this "index"
http://forum.xda-developers.com/showthread.php?t=1975842
try some of the AOSP ROMs and see what's best for you. Since there is no best combo for everyone.
Try EVERYTHING! Every phone is different as is every person.
I could just go on about how I now swear to Trinity and AOKP, but you'll never really know the answer to your own question unless you experiment. The experimenting is the best part :3

I use ParanoidAndroid with Harsh's kernel.
Of course this is subjective, but having tried all kernels (except Matrix and Trinity) Harsh's one is the fastest and smoothest one with good battery life. I think other kernels have better battery life as they disable mpdecision, but this comes at the loss of smoothness which I personally prioritise.
As for the ROM, I haven't tried any since I flashed PA first. I don't think I'm ever going to even consider switching ROM's - that's how awesome it is :good:
But as everybody else is saying, you have to try everything yourself, not like that's a burden since everybody on XDA loves flashing stuff. It's fun!

Sorry i didn't make this clear earlier. But i care MUCH more about battery life than performance. I use my phone constantly, wether that means texting or reddit or games. I'm sure the nexus' hardware can more than keep up with these tasks but I'm getting relatively poor battery life.
I'm a gamer I use rasbeenjelly rom and motley b31 experimental. I get better battery life and performance than stock rom.

Really? I've flashed dozens of ROMs between my Galaxy Nexus and N4, and have always used TiBu Pro without fail to quickly restore my apps. (then again, all my apps are from the Play store).

That's what I'm running right now! :good:
The reason I recc'd SR5 was because I found it faster than SR6. Heck, with Matr1x 5.5ocgpu487 (which itself is marginally faster than Matr1x6), I was scoring just over 20000 on AnTuTu with SR5.
I just benched SR7.2 with Motley b31oc1678, gave a pretty nice AnTuTu score of 20900, which is the same as what SR5 gave. So I'd give a thumbs up to this combo -- it also feels as good as SR5! (Running Trinity 91L at 1728 oc'd would undoubtedly bump that above 21000, but I couldn't tell the difference between running Trinity at 1728 and Motley at 1678 in daily use)
Do have to say that Rasbean Jelly and Trinity 91L was blinding fast, very noticeable in regular use; totally supports the >23000 AnTuTu score. (But I can't tell that big a difference between that combo and Liquidsmooth 3.2, which is unsupported by its 19000 benchmark. Yet another reason why I feel benchmarks are somewhat worthless when compared between entirely different ROMs)
It's all really subjective; objective tests like benchmarks are so confounded that only data mongers like me bother to use them :silly:
With Motleys I get 16000 at 1024
19500 at 1242 but then the increase is negligible. 22500 at 1642 for me.
I have been runing at 1024 and every game is perfect. Undervolted to 650 at 1024

Your title will make you become a good prey for trolling or noone gonna answer. It's very subjective to tell which ROM or kernel to be the best, and the ROMs and kenels in this 4rum are updated day by day. You can try and decide by yourself.
BUt I know your concern, I used to ask myself and everyone the same question. Hence I'll give you my review for stock ROM + FrancoKernel. These two gives me more than 4 hours onscreen + wifi (sometimes off) + sync (contact, gmail). I also UV 150mV to reduce the heat (at least that's what i am thinking). Heat? 20mins with NFS MW, my phone reaches 47celcius. 45 min -> 55celcius (it's not fixed).
Try them all and see what's best for your needs. Many roms and kernels out there.

OP as stated, only you can determine what is best for your device and you....just test the Development that is going on, there are to many variables involved to base your thoughts off others comments, usage & apps so on....ensure you do some reading and homework on your choice, Thank You.

[Q] Kernel that could fit to me ?

I'm searching a kernel that has the best battery life considering that i don't play games and if i play i play game like "Solitaire" these kind of little game .. And just use texting, whatsapp, twitter, and a bit internet browsing..
I want at least near stock performance though..

Try a few like Franco, Faux, Trinity and others and keep the one you like most. This is the best advice i can give you as different users will have different usage for their phones, so it is very subjective
You have to try them and see what performs the best for, under clocking and such. I swear by Trinity, battery efficient and fast. I've tried all the kernels and judged for myself which suits me better. Best way to do it everyone's views will be subjective.
Also best kernel related questions usually get closed so good luck in your hunt for a kernel.

[Q] Optimal Setup for Nexus 4?

Hi!
I got my Nexus 4 three days ago.
My Usage Specs -
I use my N4 mainly for internet ( WiFi, sometimes 2G ) and a little bit of gaming. I make occasional calls and text rarely.
I don't use WhatsApp or Facebook.
I'm using STOCK ROM+Kernel.
I'm getting around 10-12 hours of battery life, with 4-5 hours of screen-on time.
Now, I want to be able to over/under clock & volt my CPU+GPU. This is to increase battery life and increase performance, as required.
It looks like too much choice is very confusing. So, I'd like some experienced suggestions and recommendations.
So, which _ should I use? ( And, I've already narrowed down the choices a bit )
Kernel - Faux, Motley, Franco
ROM - AOSP(Stock), CyanogenMod, Paranoid Android, Xylon
Also, should I use Battery, CPU, RAM managers? If so, which ones?
What are some cool, useful N4 specific apps?
Any other tweaks and tips? - You can link to other xda threads, if available.
I will be unlocking and rooting tomorrow, once I decide which kernel+ROM to use.
Thanks!
Ram and battery managers are not necessary. You have 2GB of ram. Battery saver apps do not work. besides you said you're getting 4-5 hours of screen time. That's great!
Download greenify. It's a great app.

Hi,
I understand that you are trying to prevent flame-wars and the like, however, I'm not looking for 'the best kernel/ROM'.
I want to know which combinations and configs other people have used, and I'd like some experienced suggestions.
I'm finding it confusing to differentiate between the variety of kernels and roms available, so I wanted some recommendations - preferably, with reasons.

I use Paranoid Android with its stock kernel. For me, no other rom can compare to Pa on the nexus 4! Not even cyanogen mod is as fluid, stable, and efficient. With my current setup I get around 16 hours battery life (5:30 am-11ish pm), with ~5 hours screen on time. I don't use any task killers or memory managers. I just make sure to force close all my apps when I'm done with them, and I reboot the phone every 24 hours to keep it at its maximum performance. Although my usage is slightly different. I use my phone mainly to browse the Web, text and occasionally snap some pictures and check instagram. Hopefully this helps you out a bit

Trinity and Franco kernel works great with PA. And so does semaphore. I use Franco kernel mainly because I get more screen time than any other kernel I've used. Franco kernel delivers a balance between smoothness and great battery life.

Okay, and you use PA too?
Also, how does the kernel affect smoothness? Shouldn't the performance be the same as long as you don't change clock speeds? Or is it due to the new governors that the kernel uses?
Also, what about motley kernel? The thread is very spartan, and I can't glean much info about it.
Has anyone tried Xylon? - it looks efficient.

I've tried the Franco kernel before but I find the stock PA one to be perfect as far as colors go. I've never had an issue with smoothness using it and I don't even worry about clock speed or governors. As far as xylon goes, I found it to be very washed out using the stock kernel that comes with the rom, again in terms of display. When I ran xylon for a few days, I ran into a few hiccups in performance that weren't acknowledged, even when running with different kernels. I've also tried AOKP, Cyanogen, and axiom, but I always return back to paranoid

HI!
So I have experimented and tested most of the major kernels and ROMs.
AND..... My selection/combo for now is:
kernel - Franco Milestone 2
ROM - Carbon 1.7
I tried Paranoid Android, but I didn't really like their interface adjustments.
And, just CyanogenMod is boring, IMO. Xylon, too.
Carbon has great customisation, and the specific adjustments that I like.
Thanks for the help!

Drivers with code from Code Aurora. They *may* fix stuff like slow WiFi speeds and delayed notifications. I personally use them but if you don't experience any problem with WiFi then I suggest flashing the normal ones. :fingers-crossed:

I think I'll use the normal ones.
My internet speed is 4 Mbps and I don't use my WiFi to transfer files at all.
At the moment I'm getting the speeds I can technically get. So those won't help me, I guess.
