So I was running stock for a very long time, and I had insane battery life. I usually got 5 and a half hours of screen on time with my usage which mostly included browsing and a bit of youtube-ing and maybe the 30-40 minutes of gaming. I never used it conservatively though, I just didn't need anything else. I had GPS and bluetooth off and I used WiFi only at home (2g, not 3g, when outside).
Anyway, a month ago I flashed PA 3.99 and my battery life has reduced. I only (relatively) get 4 and a half to 5 hours of screen on time. Is this normal? I thought I'll get better battery life with a custom ROM. I'm still running stock kernel BTW.
PA is giving me too many issues including random reboots so I've decided to flash either CM, PSX, Carbon or PACman (help me in deciding from these?). Should I flash a custom kernel too? I'm leaning towards Faux for the battery life but I'm scared it might reduce it!
PS : I just flashed the PA ROM, so I'm still running the stock kernel, right? The thing is, on my older phone, some devs bundled the ROM with a custom kernel. My kernel version says 3.4.0-perf-g04b6fae. Sorry for the noob-ness.
There are just too many factors, the coding, apps installed, kernel, optimization, the user usage pattern, signal quality. It wouldn't surprise me though, but if it work for you stick with it.
Kernel alone doesn't determine the whole picture. I don't use PA, but I don't think it use stock kernel since stock usually ends with "mtv.corp.google.com".
You can check these battery life benchmark for kernels if you want to try, however, I don't go by them: http://forum.xda-developers.com/showthread.php?t=2449982

I did exactly the same, and feel exactly the same... I have the same apps, same usage, and I feel like I have a few hours less with this ROM (and same Kernel). I'm planning to give Franco a try, I think, although according to that benchmark it won't give a great battery life either... Have you already tried anyone?
Just a noob question, I haven't yet completely understood that thing about builds. When I was completely stock I was in JWR66Y. Then I only flashed PA 3.99 RC2 (for that build) and now in settings it says JLS36G. It now means that I have to care that kernels get on well with JLS36G? I thought I would stay in JWR66Y.

there are two versions of 4.3..one is stock (JWR) and one is AOSP (JLS)
the AOSP build is more latest in a way..AOSP build has more speed but has random freezes for 2-3 seconds (should be fixed in most of the roms by now) while stock JWR build is not as speedy as AOSP but doesnt have those random freezes.
And yeah you would now have to flash a JLS kernel rather than JWR..and if you want a kernel with good battery life..try hells core kernel which IMO has the best battery life and performance

after trying multiple different ROMs, kernels, etc.. I found that I wasted a lot of time getting geeked-out over nothing special. Sure, it's fun.. exciting... learning.. some minor features that are cool.. but, I do desire to have those hours of life back. Also, I experienced many more downsides than positives. Battery, lock-ups, random reboots, etc. A rooted stock device has served me very well..

Thanks! I had read about the difference between AOSP and stock, but didn't know/remember that JLS always AOSP. I think I felt this one better than stock. I've already been 4 days with it and I'm really comfortable being able to change dpi individually, custom it and use Pie, too, and stability is just as in stock, I think (I only got restarts in both of them while using Skype :S ). I didn't even worry to try CyanogenMod (in all my previous phones I had used it, always).

That's my concern in trying with new, custom kernels. Right now I'm just fine (although I'd like to have a little better battery life), so I'll keep reading and see if it's worth changing the kernel .
Thank you!

the hassle come with flashing a new rom because you have to do a factory reset..with kernel though its pretty simple just wipe cache/dalvik cache flash kernel then reboot. So just try the kernels you think are interesting and if youre not comfortable with it then flash another one..i know its a hassle with rom but not much with kernel.
P.S you guys should really try hells god kernel. Ive been personally using it for 3 months and the battery life is just amazing
I'm getting good battery life with KitKat.

Yeah, I've already flashed kernels in other phones, but never had this risk of compatibility issues due to different builds.
I've read that JSS kernels in JWR roms cause problems. Is the opposite not true? I mean, right now I have a stock JWR kernel running in a AOSP based ROM (JLS). Could this compatibility problems cause boot issues too? Of course, always with tested kernels. Or I'll always have the opportunity to boot into TWRP and flash a new kernel, until one works?
And one last question. When I look for AK's 4.3 kernel I only read JWR and JSS. Why doesn't it say JLS? Is it the same as JSS, then?
Thanks!
I can vouch for the above statements. I'm liking Hells core kernel. It's fast and has great battery life (as good as stock, maybe even slightly better). FWIW, I'm using Carbon ROM now and it's MUCH better than PA.

Sorry i forgot to mention that JLS and JSS are the same build JLS being the latest one..so there is no difference in JSS or JLS. You can flash a JSS kernel on a JLS build no problem. But if youre build is jwr then your kernel build should also be jwr because yes it causes compatibility issues if you flash a jwr kernel on a jss/jls build or vice versa. In every ROM the stock kernel is matched with its build number. If its a jwr ROM then the stock kernel would also be jwr and vice versa.
Flashing a jwr on a jls/jss rom or a jls/jss kernel on a jwr rom might cause the phone to be in a bootloop (not going past the bootanimation) and even if you get it to boot up the performance would be lacking and it might cause random freezes, graphic glitches and or random reboots.
However there are some roms that are a hybrid which means its a combination of jwr build and jls/jss build. In that case you will flash a jwr kernel only nothing else.
Hello everyone, I'm new in here and I'm using Nexus 4..
I really want to flash custom ROM, i need better performance and battery life..
I don't care about features or costumize anything except performance..
So what ROM should I use? And I'm planning to flash custom kernel too. I heared Franco kernel is great..
But besides that, I'm totally noob with root and flashing rom..
Thanks before. Your suggestions really appreciated .
Stock. Simple and no need to flash it over and over again with pretty useless nightlies.

If you want a few basic custom options such as configurable tiles, battery percentage, torch, and a screen-off button to save your physical power button, I would go with Cataclysm ROM. This is stock with those few options added. I feel it's like what Peter Alfonso used to do with Bugless Beast in the past.
I'm waiting for Cataclysm 4.4 which will be out soon now the factory images are released...
Thank you!
But it not satisfied with my battery life. I want to flash custom ROM and kernel because i want to improve my battery life and performance also..
So what should I do?
I heared there's a mod to raise battery life and performance..

Really; try Cataclysm ROM. It has battery saving features such as smart 3G, do a search and read about it in the Forums.
Install stock kitkat 4.4 and enable art
I usually use Primal. But so far Stock 4.4 is as fast maybe even faster. Haven't really got a good battery read on KitKat yet. I would get 5hrs screen time out of Primal. With calls, surfing, txt and camera.
IMO Carbon based ROMS seem to be the best.
@r3act: Thanks! I'll give it a try..
@Goku: I'm sorry, i appreciate your answer, and i don't know about deleted ppost. My bad..
if you're new to the whole flashing thing dont start.... once you start it aint gonna end. i started with my N7 and have flashed waayyyyy too much roms to end up right back at stock 4.4. on my nexus 4 i have not yet flashed any custom roms cause i found that stock rooted roms have the most reliability,stability,better battery life, and most usability from all others.so far with my 4.4 stock i have 12h39min. and 19% left. thats through talking,surfing the web downloading,and playing games. slightly heavy usage today. i think 12 hours is good enough for me. my advice flash 4.4 stock,root it and dont flash custom roms. its fun with all the features but stock is always better. my opinion.
Thanks everyone! I'll consider it..
@podagee: i thought that custom ROM can improve batterylife..
After reading your reply, is root improving battery life? And which root app that you installed?
I think this is what you want: http://forum.xda-developers.com/showthread.php?p=47439423&highlight=battery#post47439423
Best battery might be Semaphore kernel + Purity ROM 4.3
Good luck!
root doesnt improve battery life it gives you privileges to all areas of your device. i use mine for removing apps that are built-in the rom,bloatware. the ones you couldnt remove now can be removed when rooted.i usually keep my device simple by removing playbooks,magazines,youtube(replace with ogyoutube) google currents...etc.... anything i dont use. i install cleanmaster,to clean up leftover cache and to free up occasional ram space.
as for rooting the 4.4. follow the guides they have in the Q&A section if you use adb&fastboot.unlock your phone. install your 4.4 stock.flash a custom recovery,i like twrp. then flash superuserv1.65 in custom recovery and your good to go.
There is no certain ROM/Kernel you "should use", your use may vary to someone else or vice-versa so battery life may not be as good for you as it is for someone else. There is no best, head over to the development section and see which best suits your needs.

Hi guys , i've just flashed my samsung note 3 to CM12.1 and i am experiencing huge battery drain issue.
Any kind souls over here to assist a newbie ?
So sorry to trouble.
Those AOSP ROMs will never give you as pleasing battery backup as TouchWiz based ROMs, but still first thing is, you need to mention what processes are sucking the battery life. Install BBS and mention here.

Is there any recommended ROM which i can use for a stable OS and no battery drain issue?
I cant post screenshots yet as my post count is less than 10
Is DarkLord's ROM good?

Use any TouchWiz stock ROM, or at least stock based ROM custom ROM. If you want a full featured ROM go for Arya, if you want a ROM as close to stock as possible then go with Alexender's stock ROM.
In any case, you do need to monitor what app/ processes are creating wakelock via Better Battery Stats.
Hi guys. I'm using Liquid Remix 9.0. (latest version, projectk r23 kernel and nova launcher)
Can you tell me about the ROM and kernel that is very stable and the battery is very good? Or should I go on?
thank you to everyone who answered my question
U may disagree with me, but honestly, stock rom is one of the best ones i've used, in terms of stability and battery. Not many other custom os managed to achieve similar battery life as stock. Hope this helps!

I agree and im still using stock since i bought my phone
The less customisation you have the less bug you have.
Stock is the most stable, battery friendly without tweak
You can still put magisk / xposed and a custom kernel to win some battery % if you know what to do
I agree with them, after installing most custom roms out there i always came back to stock. Maybe pie could have a better battery usage, but i experienced lots of bugs even in so called 'stable' firmwares.
What kernel is the best with stock rom?
