To change the settings on your current kernel, it would be best to see what others use in the kernel thread. But basically you need an app from the play store. Kernel tuner and trickster are popular choices. But be sure you know what you're doing before messing too much.

But for the kernel you are on, assuming it still uses the aroma installer, just flash it again and change settings in aroma during install.
[Nexus 5 General] atomomega:
Ever since I flashed my first kernel, I've seen little to no difference in terms of battery usage. The real differences are, at least from my experience, the available governors/schedulers and the freq table.
[Nexus 5 General] Primokorn:
Switching to different kernels doesn't really help in terms of battery life. Uninstall useless apps, disable power-intensive features, block bad wakelocks and switch to another mobile provider to improve your signal :)
[Nexus 5 General] AndrasLOHF:
Governor and screen off caps can make a world of difference depending on usage. For instance if I stream music over wifi or data using a bluetooth headset using a governor that is prone to spiking max frequency without a screen cap compared to a more conservative governor with a screen cap; I can easily half the battery usage in comparison to each other. For screen on stuff, idle time, etc; what apps installed/how phone is setup matters more than what kernel you're using.
[Nexus 5 General] atomomega:
That's basically what I was trying to say. I've never flashed a kernel expecting to get more battery life.
[Nexus 5 General] bblzd:
Unfortunately many still do. "Which kernel/ROM is best for battery life?" is one of the more commonly asked questions.
[Nexus 5 General] DroidDredd:
So true and it all happens to be in your Kernel settings, no matter the kernel

Sorry if this is not the right place.

I have a dual boot with Paranoid Android and Firefox OS. When I tried to boot to Firefox today it gave:

Kexec-hardboot support is required to boot this rom.

Install kernel with kexec-hardboot support to your internal rom

How do I know what kernel I can use with my system and is it as simple as downloading the zip and installing through MultiROM?

Android Version 4.4.4

Paranoid Android Version 4.45

Kernel Version 3.4.0-gd59db4e android-build@vpbs1.mtv.corp.google.com #1 Mon Mar 17 15:16:36 PDT 2014

Build number pa_hammerhead-userdebug 4.4.4 KTU84P 109 test-keys

MultiRom TWRP 2014-11-15(v2.8.1)

FireFox OS fox-20140603-0.4-valox

thanks
[Nexus 5 General] Elluel:
MultiROM requires the mentioned kexec support in the kernel to be able to switch without having to replace things.

Just look for any kernel that has it (it should be mentioned in the OP of a kernel thread if it's supported), and flash it.

Your current kernel is the stock one from Google, which does not have the required patch.
[Nexus 5 General] petmor:
That worked. Thanks
[Nexus 5 General] rah94:
i should just flash system.img,right ? what about boot.img ? is it necessary ?
[Nexus 5 General] KaSrAHiDe:
if you wanna jus go back on Stock kernel flashing Boot.img is enough but if u wanna flashing whole device needed to flash both

Hi [MENTION=855746]flameinthefire[/MENTION] consider renaming the thread title. Like others said before, this will be a kernel lovers thread. Maybe "kernel discussions" or whatever you prefer. However, I add this to the index, as there was a request about a thread like this, so thanks for starting it :)

Stock kernel is lag free.

Custom kernel reports should be taken with a grain of salt since each dev updates their kernel on a regular basis!

Just cause r-whatever is lag free today, doesn't mean it will be lag free in 2 weeks. By then there will be several version bumps...

Once development matures, we will have some decent kernels that are lag free.
[Nexus 5 General] movielover76:
After owing the gsm nexus, nexus 4 and now nexus 5. I've found stock kernels to just be more stable in general even late in development cycles custom kernals always have some bugs and I prefer the stability of a stock kernel.

I've said it before. I don't understand that a discussion board about phone development doesn't permit discussion about something that is integral to the development of the phone. We all can't try EVERY kernel and EVERY rom. And there are literally thousands of pages to wade through if you were to read the threads for each individual kernel and rom. A thread such as this is very useful to some of us. The ban on kernel/rom discussions seem very arbitrary and only applied simply BECAUSE it's a rule.

I know that everybody's configuration and use is different and it's hard to generalize, but such generalizations happen in virtually every corner of this forum and are not banned. The only response I've ever seen from a moderator is "They're not allowed." By nature, people are more inclined to follow a rule when they understand why it's there. Educate, don't dictate.
[Nexus 5 General] benkxda:
Hello [MENTION=1811927]simms22[/MENTION], thanks for that link, but I knew it already before.

You don't have to be frightened to be compared to other kernels. I liked your high speed kernel for the Nexus 7 (2012) very much. But maybe you got me wrong.

If you read my post again, you can see, I refer to a comparison like we have for the ROMs. This is a unbiased but really fair comparison. It's not about xyz is the best because of its theme is blue and I like the logo. It's about having pie/halo etc. or not. You can take a closer look to this comparision if you want to. It was also featured on the portal.

However, I prefer those comparisons, because I can choose, which ROM is best for me. Maybe I search for a slim one or a ROM with plenty of features... I check the ROM comparison to get the right way. For example, if I need PIE, I won't have to try ROMs without and don't have to search, which ROM has PIE and which not. And again, I don't need emotional reviews of ROMs, or in this case, kernels. I need facts and if a kernel lets me overclock my CPU up to 2,5 GHz, I wanna know.

To [MENTION=2864014]marleyfan61[/MENTION], I think XDA wants to avoid threads like I told before: kernel x is best, because of y and z. I don't need those threads either. But I wanna see, which kernel matches best for my needs. Like you said, I cannot really try every ROM and kernel, I don't have the time for this "I try everything" project. I think you need the same comparisons, like I wanna see. Check out the ROM comparison (Google Docs sheet). Even the Developers of the ROMs are working on this comparison!
[Nexus 5 General] simms22:
1. before the rule, every other thread was a best kernel/rom thread, literally.

2. kernels react differently on every device, we all have differing needs, and theres no fact to support calling something a best kernel. for one person it might be best, and for someone else it could be the absolute worst.

3. every best kernel thread that was around before the rule eventually started a fight/argument. the kernel a person uses is going to best to them, we all use differing kernels. so everyone thinks that they use the best kernel(or rom). this is what starts the arguments.

xda got tired of all these arguments/fights, and by the mass amount of these threads, so now they do not allow them. best advice is to try out all the different kernels, find the one that fills YOUR needs and reacts best with YOUR device. it takes seconds to flash a kernel, you have time to try them out.

---------- Post added at 01:47 PM ---------- Previous post was at 01:42 PM ----------

lol, im not frightened. i wouldnt care if i was the only person using trinity kernel, as its made for a small group of friends. but i do like to share! anyways, even though i personally use only one kernel, i dont push it onto people. i tell everyone to try as many kernels as possible, as thats the only way you will find what your device reacts to the best :)
[Nexus 5 General] benkxda:
Looks like you're not against this kind of comparison, the ROM comparison is based on (really, take a look, ROMs in friendly neighborhood). Again, even the ROM developers work on that comparison or have "official" or "unofficial" people doing it for them. Do you think that would work and it's ok as it's not a fight but a clean listing of features?

BTW, I did not use trinity, it was a kernel hyperclocked up to CPU at 2 GHz and GPU at up to 700 or 750 MHz. However, used this one a long time.
[Nexus 5 General] simms22:
i remember that kernel! but the n5 at 3014mhz is faster :)

a comparison for roms is one thing, but for kernels its a bit different as many kernel developers dont work on features, but on making the smoothest best reacting user experience instead.
[Nexus 5 General] muyoso:
So back on topic, kind of. Is there any kernel out there that fixes the wlan_rx_wake wakelock? I am on Faux right now and have it just as bad as I did on the stock kernel.
[Nexus 5 General] Warwolf_1:
I would ask if someone can help me for the choice of custom kernel. I' m undecided between:

-Hammerhead AKA Nexus 5 Hybrid

-Bricked-Kernel Nexus 5

-ElementalX 0.14

-Franco kernel

If anyone has tried these kernels can recommend me the best in terms of of performance, battery life and doubletap2wake.

Thaks :)
[Nexus 5 General] 5FOOTER:
I am very happy with the Franco kernel r23 stock ROM great battery and performance.
[Nexus 5 General] floxrin:
same here. good combo, no headaches
[Nexus 5 General] FoxhoundLZS:
actually,i do not think stock is the best,custom kernel is based on the stock ,so it may do better than stock
[Nexus 5 General] GragonV:
So far, I'm satisfy with the chaos :)

Since it has the function to set the color (although only one preset profile) and the good d2w s2s s2w features (which has a bonus feature turning the phone off by power button will disable the d2w feature, very useful)

still not come up with the best setting to make the phone be smooth and maintain the good battery life yet... but only if some other kernel can come up with the full supported by faux123 or franco app to set the color like in Nexus 4, I think I will stick with Chaos

any suggesting for my need is much appreciated :P
[Nexus 5 General] Laggalot:
i soon will get my n5 so i cannot test just yet ^^ but i already make a plan what to install..... i want to stay at stock rom at first ( maybe till android 4.5 ^^) i cannot decide between franco, elementalX and faux! can anybody tell me which one does give the best battery life? 3-4 hours SOT is what i usually get with my galaxy s4 at the moment.... i dont need tap to wake and stuff since it drains battery.... my guess is that franco comes first, then elemental and faux ?

[Nexus 5 General] Enddo:
for battery life i recommend Franco
[Nexus 5 General] simms22:
for every person that says a certain kernel gives great battery life, there is another person that says the opposite. this is for every kernel. thats why best kernel/rom threads are not allowed. good battery life does not depend on a kernel nor rom. battery life depends on your personal setup, your personal usage, and very much on the quality of your phone/data connection. thats it.
[Nexus 5 General] Laggalot:
the last point you made is the worst :( in austria there is only good signal in citys but live on the country ... ^^ although.. iam not that much at home ^^

sent from my i9505 or nexus 7(2013)
[Nexus 5 General] simms22:
it IS the worst unfortunately. and unfortunately thats why many keep trying to get good battery life but cant. the signal quality is probably what will affect your battery life the most. fortunately for me, i live in nyc. and have great signal quality in 95% of the areas i visit or go into. but the majority of people live in areas with average signal quality, and get average battery life.
[Nexus 5 General] Pumå:
Quite intersting how the experiences differ. For me Franco Kernel gives the best balance between perfirmance and battery life. I UCed two values down and it feels as smooth as stock, hardware-hungry games and their fluidness is unchanged. Kinda strange that people report lag and other issues. SoT on same usage is about 50-60 minutes better. I watched enough the kernels and FK beats the rest on my device.
[Nexus 5 General] simms22:
its obvious that the experience should differ. we all use our phones differently, have differing usage patterns. and the phones themselves differ as well, like differing setups, differing voltages, etc. unfortunately, whats great for me can be absolutely terrible for someone else. if everything was exactly the same, then the experience would be similar for everyone. but, hardly anything is the exact same.
[Nexus 5 General] Enddo:
im glad you think that
[Nexus 5 General] simms22:

comparing kernels/correct testing methodology

brace yerself, nuance ahead... Your point is true, to a point. While our use-cases are always going to be different to a point between us, *my* use-case is almost identical every day. I spend about the same amount of time in 2 places (home/work) doing about the same things. sheesh! talk about a rut! and while my usage may change slightly, the amount of drain while screen-off is very comparable.

So, while my assessment of a kernel's battery life, say, is specific to my use-case to a certain degree (some are better sleepers, some at maximizing SOT, for eg), I *can* provide a useful comparison of several kernels for *my* use-case. This can actually provide useful data about how well a particular kernel sleeps for eg, or how well it extends SOT (assuming the usage is very similar for each kernel tested). People providing information should be careful to make sure their usage is comparable, that they are using stock settings, and that they mention which rev of the kernel they're talking about as each kernel changes throughout the dev cycle.
[Nexus 5 General] simms22:
see, this is the post where i agree with you, somewhat. my use is always nearly identical every single battery cycle. every 50%, im at 3-3h20min sot, and at 5%, im at 5-6h sot regardless. i use the phone nearly identical nearly every time. for my setup and my usage, i can judge battery life fairly accurately, regardless of kernel/rom. the problem is, my usage/battery life is going to be different to others usage/battery life, even though we run the same kernel. and its not only the usage that differs, its the signal quality, and their personal setups. i can compare kernels and judge battery life, for me. but you cant compare two different devices, because there exists too many variables. anyways, i get the same battery life on pretty much all the kernels ive ran. its not because of the kernels, its because of my setup, usage, and signal quality.

i am part of a kernel team, trinity kernel. i get 5-6h sot every single day. but one thing that you dont see is me pushing trinity on everyone.there is a reason. even though i get great battery life without undervolting or underclocking, and so do others, there are just as many people that run the same kernel as me yet only see 2-4h sot. thats because of of other variations. the apps they use, their choices in settings, and that all important quality of phone/data connection. battery life is more of a personal thing as opposed to a kernel thing.
[Nexus 5 General] razholio:
yes, exactly, and this is why you cannot tell people they will get 5-6hrs SOT because they're usage (which in my verbage here includes everything from SOT, apps, radio signal, GPS usage, location tracking, etc) is going to differ from yours.

however,

what *can* be useful is you (with your consistent usage) testing each kernel and reporting your results. I can't take your absolute assessment of each kernel, but I can take them relative to each other. If one kernel stands out as having highest SOT or standby, I may want to *start* my search there.
[Nexus 5 General] simms22:
then we agree.

which is a reason why "best" kernel threads arent allowed on xda, there is no best. there is just a best for you(or me). and why its best to try out many kernels to find your personal best :)
[Nexus 5 General] benkxda:
Those "best kernel" threads would just consume resources and won't bring up any changes or ideas.

I would like to see a feature comparison. Of course not about listing a special secret patch which will bring you 200% performance and 5 days more battery time. I think about features like fast charge, USB OTG, OC/UC/UV, S2W/S2S... basically things you can set up or change in most kernel managing apps.

BTW, I tried Nexus 5 with 3 GHz. For a few moments high performance, but the a reboot. However, the Nexus is fast enough for all my needs even at 1.5 GHz ;)
[Nexus 5 General] simms22:
not only consume resources, but start arguments. since we all believe that the kernel that we use is the best.

anyways, why dont you put some time into putting a comparison thread together? you seem interested. most kernels would be easy to put a feature list together for, since they proudly display all their useful, and useless, features in the op. some kernels will be harder to do though, since they dont focus on a feature list.
[Nexus 5 General] EarlZ:
I am using R32 with corrected colors and yes I did start to notice some animation stutters since I've been using custom kernels and ive used the stock kernel for a long time.
[Nexus 5 General] benkxda:
"...and useless" lol. Ok, for everyone some features are useless, I think.

But bringing up a kernel comparison is a good idea, my available time is very limited. A lot of time I spend on my threads and all of them are alive and need to be maintained. Let's see, if nobody starts a kernel comparison thread and some of my older threads can live with much less of my time, I would do it. If this happens, it would be nice if some kernel developer could join/contribute ;).

Hey, i instaled franco kernel and i want to go back to stock kernel, how can i do that?

Trinity's Kernel is amazing.

As soon as I got my N5, I unlocked the bootloader, flashed PA B3, and tried the stock kernel packaged with it. It was great for a stock kernel, and ran just fine. However, I wanted to push the S800 a little harder, so I tried out Franco's kernel.

Seeing as I'm not a kernel developer, and don't really know how to accurately explain pros/cons, I'll just say that I enjoyed Franco's kernel for the N5; however, I decided to then try ElementalX's kernel.

ElementalX's kernel was always my favorite on the HTC One, it was highly customizable and I'm sure a little bit of the placebo effect was in play with all the buzzwords thrown around with it. However, this kernel was deadly fast. I noticed everything running just swimmingly.

Lastly, I tried/am trying Trinity's kernel. If you google the default TCP Congestion model 'Veno', there's a thesis someone wrote about it as it combines Vegas and Reno models. It seems pretty cool, but I'd have to do some exhaustive testing to see if it's really worth it, but I think adding in interesting things like this is a very cool thing for people like me who enjoy testing and playing around with settings. The default scheduler is also pretty great (SIO), and running at 2.8 GHZ I have flawless performance.

I didn't spend enough time with any of the 3 kernel's above to give it a solid battery test, so I can't comment on that. But honestly, I've enjoyed Trinity the most so far.

Faux if you know how to opt in for all his beta apps like fauxclock and faux sound with aosp Roms.

[Nexus 5 General] P.Mobile:
i kno there is no best kernel.. i test all kernels.. but if someone wanted my opinion i would say franco kernel for battery life all day... other kernels are also good but i always go back to franco.. i love trinity also but my cpu's jump all over the place even when i dont touch the screen.. cant figure out why:confused: and i kno people will say thats because my phone doing stuff in the back round but i have tested this many time trust me.. other kernels dont do that for me.. when i dont touch the screen for say 20 + secs the cpu are just chilling at the lowest 300GHz.. on trinity for me i could not touch my screen for 10 mins and the cpu's are still jumping all over

How do you guys actually use franco kernel.

1 - do you just flash and play..? (default setting from franco kernel)

2 - do you flash it and did a little tuning of the frequency/GPU/scheduler..?

3 - do you flash it and have extreme mod/tuning to get the ultimate power performance..?

4 - do you flash it just because of the overwelming respond to this kernel..?
