Best Kernel out there?

which kernel out there is the best right now? in battery life and speed

theres only one that fits best battery and fastest.. trinity kernel.

I like Trinity but Motley also did very well for me.

This^ look at it this way. The nexus allready has great performance, it will handle any game you throw at it. (Unless not optimized for tegra 3) so wht else do you need? A kernel that gives amazing battery life. And what kernel is that..... \l/ TRINITY \l/

TRINITY without a doubt!!! Fast as hell and almost unbelievable battery life!

battery right now..
speed..

Ill say motley. I tried trinity kernel. Its good. But I getbetter performance,stability, and battery life with motley. All these battery screen shots really mean nothing. Why? Because none show real heavy use. I can easily get the same stats or better with light to moderate use. Show me some stats showing 8-10+ hrs of screen on time. With some heavy app or game usge. Anyone can use device for a few hours. Then leave it in deep sleep and show the same or better stats.
I've tried all the kernels out so far. They are all good. Its a matter of personal preference of features you want. Some pack things others don't. MOTLEY 'S ATM is the only linaro based kernel. So its using new additions/components. Better optimized. Benchmarks are cool but its real world performance that matters most.
I'm running stock rom with motley latest linaro based kernel with Zram, then CPU overclock @ 1.624ghz and gpu overclock @ 520mhz. I'm also undervolted -75mV across the board. So my temps stay low. Which equates to my device running at a higher performance speed longer.
The best thing about stock rom is I can measly flash different kernels and not have to worry about flashing a rom and setting my apps n all THST all over again. I can flash a kernel with no wipes and be good. Plus stock rom is the most stable ATM. Can't lie though, I am anxious to flash some roms. THST paranoid Android one looks really good. Along with the pure linaro based rom. That's the great thing about choices.
Its not a matter of who has the best kernel. Its more about what you looking for in features and personalizing your device to cater to our needs.
Asking who has the best kernel is like asking who is the best developer on xda. I don't think that's fair to the developers as they ALL work hard on roms or kernels. Forget the popularity contests.
THEY ALL THE BEST lol. Some are just more seasoned than others. Which is OK. I love the fact we have variety of things to choose from. I've been impressed with trinity kernel, based on scores I've been seeing. But I'm also impressed with faux kernel and its a more straight forward one with lots of new Linux commits and additions. All the kernels have a personality of their own. I love the fact that twrp makes it very easy n simple to try out any kernel I want for nexus7. No matter who makes it. Every developer has its followers. You also have people who like to try out different setups.
Choice is a good thing! That's what I love about Android.

I've got to say for me trinity is the best kernel for the Nexus 7, updated daily and great communication with the dev makes this an awesome kernel. The trinity toolbox app is the icing on the cake.

1. trinity kernel has been using linaro since april of 2011, on the nexus s, the gnex, and now the nexus 7.
2. zram is a placibo. theres nothing there
3. stock rom is good, but i prefer a pure aosp build. no, they are not the same.
4. and the last two paragraphs are the absolute truth.
5. really, you should try them all, let your device tell you which kernel it likes the best

Thing with zram is, its not for getting higher benchmark scores or immediate performance. Its more so for heavy multitasking. Is been proven to help. The placebo is on people who think its supposed to provide some immediate result. If someone is a heavy multitasker on their device, then zram would benefit them. If you not much of a multitasker, then zram will show no Bendix for you.
You are right though, about trying out different kernels and such. Pure aosp rom sounds good. I just hate having to reset up my apps n stuff. I know titanium good for that but me personally, I'm waiting for roms to mature more and have most things, of not everything working. All roms so far seem to have something not working yet. Which is fine. Nature of the beast.
I think I might give trinity kernel another try. I did buy the tkt app. But never used it in conjunction with the kernel. I bought it just for the automatic script it runs..lol plus to show support. I heard tkt app works best with trinity kernel plus allows you to tweak features only in trinity kernel.
Ill download the latest build Trinity has and see what's up. Performance and better battery life is always a good thing. Its gpu is overclocked to 520mhz also?

Trinity HANDS DOWN its been 3 hours on sleep and ITS still at 100%! + the ridiculous speed along with the power saving features. I may be new to the Nexus 7 scene but this is hands down to godly .

im not sure if gpus oc...but when u underclock..theres absolutely no performance difference..and saves battery too! 102mhz-1100mhz on demand/deadline..god like battery life. 4 hours screen time...still 45% left...shouldve been more if i didnt flash roms in between battery life. also under clocked, gta 3 and cs portable runs great and smooth still.

thanks to simms, I tried out trinity again. I flashed the latest builds. ran some benchmarks. for some reason, my device doesn't like the highest speed on benchmarks. it kept rebooting during them. so I stayed at 1.5ghz. governor I used was performance and on demand. for scheduler I ran with deadline. i forced cpu online and put fysnc on faster, thanks to TKT app. on quadrant, I was more concerned with seeing if I could achieve those crazy high I/O scores. which I did. my overall score was good but I've gotten higher on motley. it could be higher on this kernel if I get the 1.6ghz+ speed to stick. I was more impressed with my rl sqlite benchmark test. scored 18 seconds overall. which blows away the competition.
so I'm impressed with latest version of kernel. definitely better than the older build I ran of it from before. some things I've noticed though. where is the ability to undervolt at? no option in tkt app and the voltages tab disappeared from system tuner. also, this build gpu isn't overclocked. or might be better for me to say its definitely not running at 520mhz. I could tell this by the fps from quadrant. its running 59-60fps. on motley with 520mhz gpu I get 70-80+fps. just some things I noticed. not necessarily drawbacks. kernel runs very good. just got to figure how to make higher speed stick. since I can't seem to adjust voltages on this build, I can't increase voltage or undervolt it. if this can be done on trinity kernel, let me know how. its not showing voltages in tkt app or system tuner.
overall very good kernel. will run it for a while to see how battery life is. I will likely underclock it like above poster mentioned for best battery life. I noticed nexus 7 still runs great underclocked. no lag.,no matter what kernel I'm using.
I've attached screenshots of my benches on latest trinity overclocked @ 1.5ghz. I know my device can take 1.6ghz cuz on motley I can run the speed fine, even through benches. so have to see why its not taking on trinity kernel. maybe voltage needs to be increased.

so it doesnt matter if trinity is still in experimental? its that good? i guess ill try that one out

there are more features that are going to be added, theyre being added all the time. ask gnex owners how the options grew(same app btw, different devices running trinity see different features in the app. so you purchase it once, and use it on multi devices. btw, voltage adjustment will be added, remember how new development is on the n7. also, if other developers added the options into their kernels, theyed be able to use those features with their kernels

thats just trinitys method of rotating the kernels.. starts off in experimental(every kernel is tested to boot and run before it every appears here), then it graduates to prerelease if it makes the cut, and then if you guys like it it makes its way to release. its just that trinity development is so new here that there isnt a prerelease yet

I've underclocked mines to 1.1ghz also. battery doesn't want to budge from 100% so far..lol. it's barley sipping battery. the UI and browser is fluid n smooth at this underclock. which is a good thing. the real test will come once I play nova3 shortly. if it plays lag free on this lower speed then underclocking is a winner. I set my governor to interactive though. you get better battery life than ondemand. using deadline also. with fsync set to faster.

I understand nexus 7 is still infancy, developement wise. its cool. just wondering if those features were included since the option disappeared. I could undervolt or increase voltage on motley kernel. the tkt app would let me do it on THST kernel as the section shows for it. but I like using system tuner for undervolting when I was on motleys kernel. can't wait to see what new features get added. plus once I get my new phone, hopefully there'll be a trinity kernel out for it so I can use tkt app with it. the build is very good.

Interesting, 70-80fps, more than the panel.
You were interested in battery in an earlier post, this is me feeling meh and couching most of Sunday.
EDIT: Yes, emailing, tapatalk, browsing for laptop and not finding any, reading news in Pulse and flipboard, tweetcaster and testing slice(s?), gtalk, not heavy usage obviously. Screen wasn't on unless The Seven was used though.

Poor Benchmarks on KitKat ROMs

I've been flashing all the latest and greatest KitKat ROMs for the LG LS980 Sprint variant and after benchmark testing them all using AnTuTu and Quadrant, I've noticed horrible benchmark scores. To put things in comparison the Stock ROM usually provides 37,000 AnTuTu and 21,000 Quadrant. On the KitKat ROMs, I get around 24,000 AnTuTu and 9,000 Quadrant. So the scores are about half what stock provides. I have tested this running the latest builds of KitKat DU, PA, Nameless, and CM11 to name a few. I use Furnace Kernel to Overclock to 2.5, but even without the Furnace kernel on the KitKat ROMs, I still get low scores so it doesn't seem to be the kernel so much as the AOSP base. Something must have changed in the latest builds because I don't recall having this issue of lower scores with slightly older builds of KitKat.
I just wanted to bring that to the attention of people here. If someone can confirm this that would be great too.
Also here is a link to a thread for an extensive benchmark test of CPU kernels and governors, and also a ROM to ROM feature comparison.
http://forum.xda-developers.com/showthread.php?t=2625656

Running SlimKat on my D802 I get about 33k in AnTuTu compared to 37-38k on Rayglobe Flex. BUT, just like the Nexus 5, benchmarks DO NOT matter. Even though I get a lower score on 4.4, everything from gaming to browsing runs smoother. Also, as for now, I do not recommend installing any custom kernels on 4.4 roms since they only bring instability and higher benchmark scores yet lower overall performance. I truly respect the developers who are doing their best to create stable kernels, but as for know, dorimanx's kernel is the only kernel worth installing and it's only available for stock roms.

If I got a 33k in AnTuTu that would be normal. But I'm talking about 25k in AnTuTu. That's not a small change that can be ignored. That means there is some new code being compiled that is not efficiently making use of the processor's capabilities. I'm hoping that someone will look back at their code and realize that a vital piece of code was dropped and is affecting the whole system.
If it was all about just smooth performance, then there is no reason to even have an Snapdraon 800 in the first place. We can all learn to be happy with the perfectly reasonable performance of hardware that's 2 generations old. But if we are being sold or given software and hardware that is supposed to be better or optimized then it better be and not just rely on consumers to fall under a blind veil of a placebo effect.
Furthermore KitKat ROMs are not coded to support HTML5 whereas the Stock ROM is, so websites will be more compatible with the browsers in the stock ROM.

If there is indeed some new code that is affecting then CPU, how can you explain the fact that I never got under 33k in Antutu? (I'm talking about SlimKat and Mahdi, I don't know about others)
Also regarding the placebo effect you're mentioning...so basically you're telling me that the increased smoothness across the whole OS is just my imagination and that it is better to have better results in benchmarks and slower performance? Also, the stock ROM is probably one of the most stable ROMs I've used so far so you really can't talk about lies. Both the benchmark scores and day to day usage are more than acceptable. When you decide to install a custom rom, you automatically need to make sure that you're willing to accept some sort of bugs or errors. The developers are not working for you. You're not paying them anything. So automatically you have no right to complain, just to mention the bugs so that the user developing the rom will try to fix them.
Regarding the browser's compatibility, you may be right, yet I haven't encountered any issues for now. That doesn't mean that they don't exist but as long as it doesn't affect me as an user, then I'm OK.
I'm not trying to say that KitKat roms are perfect. Far from it. But in my case, they're more than usable as a daily driver. Others may not feel this way though.

Benchmarking and roms
Ihave been searchingand searching for a nice rom with good features and low bloat n junk...derpBarebones...Comes with STweaks...OC'd to 2.7 running at almost 37000 benchmark on antutu and now lag or anything...runs VERY smooth and also gets GREAT benchmark compared to the other roms out there...also running the 3.4.1 KK kernel i think IT'S CLOUDY;'S??

Gamer Rom

I Need the Best gaming Lollipop Rom for I9505 with great performance and Battery life ?

That would be AOSP rom by the JDCTeam.
Make sure you set alucard kernel to the extreme performance or performance profile if you want better performance in gaming.

"great performance and Battery life ?" Performence or battery life! 5.1.1 CM with Alucard Kernel

if you get an alucard kernel in your rom then the raising the minimum clock speed to 810 khz on all four cores and the minimum for GPU speed to 200 khz it will help.
*gentle fair sleepers off
*arch power on
*CPU governors to ondemand or alucard with alucard hotplug
in developer option hardware overlays to off.
personally I think ktkernel was better with more options but you'd need to stick to AOSP 5.0 for that or lower

If he were to stick to older android versions (5.0 and lower) then he might aswell get KT kernel, which gives him the posibility of overclocking the CPU and GPU, something that is missing from the other kernels right now.

GPU overclocking isn't really stable, it actually takes away from the gaming experience.

How can increasing the GPU frequency, and therefor the performance, be bad?
If you overclock it too high of course it is unstable. But you should be able to take around 500 MHz easily.

I can't remember the steps you get in kt but I'm pretty sure the uppermost ones were next to unusable, 500 is only just above the standard speed.
the games are always going to have a fixed system requirement levels based on the hardware we have so there isn't that much to gain over optimisations for our roms I feel...
I always judge a rom based on how well it can play shadowgun deadzone. most untweakable kernel rom combos aren't so great fresh out of the box.

Well, I used KT kernel in the 5.0 days. I ran a gaming profile created by ktoonsez himself, which had GPU overclock, and ran stable all the way.
I usually judge a rom by how fast it opens the settings app. This presumes that the app was fully closed, otherwise it will just switch to it, wich is a lot faster than actually opening it. Also, animations are all off.
So, between the pressing of the icon and the actual opening of the app there will be a black screen (if animations are turned off). The longer you see that black screen, the slower the rom is.

one question... how to REALLY TEST and compare a kernel?
sometimes adding and modding the phone with custom rom, kernel, greenify and other manual modded cpu governor etc...... it's almost IMPOSSIBLE to understand if the perfornance, or battery life is affected by a kernel or something else.
A person could obtain a bad battery life but the culprit could be ANYTHING.....
so IMHO the easiest way to compare a kernel is the numbers of features and OPTIONS that allows it.... something like how many governor, i/o schedulers , tcp algorithms, dt2w..... and so on... because a PERFECT kernel... could be perfect in some roms.... and worse on others.....
there are too many complications about the number of apps, which apps, to use greenify or naptime/forcedoze , and a possible incompatibility with a specific ROM with specific kernel.
after all........ maybe the simpler test is to keep the same configuration of the rom for at least 1 week, make a nandroid twrp backup, flash 1 kernel, keep it 1 week ( and see results), then restore twrp with stock kernel/rom , then flash the second one kernel, keep 1 week, then restore backup, test 3rd kernel.... and so on? making it sure NOTHING CHANGE, no greenify change... no gaggressive doze setting change....
it would be nice if other people would write here they combination of precise KERNEL + ROM used to achieve a great battery life and SOT.......

No doubt all these kernels are well tuned and devs are making them better & better every day. I always use RADON KERNEL and it works with every rom just perfect, never tried AGNI though, two days back I flashed ElementX and Franco kernel but I noticed two big cores are either going "offline" or shutting them off permanently. @franciscofranco replied those two cores were thermal throttled or something (may be....) but after RADON I didn't noticed that issue, all 6cores are back online . So for now I'm sticking with radon I'll flash FrancoKernel next week and see if thingd sorted out..
Most off all I think we kenzo users are blessed to have all these big names in development thread.

Why isn´t Lineage Os on the List (a.k.a Cyanogen Mod)

I certainly like Radon best . Save battery and not lose performance .
I don't like AGNi . Because it update too frequently sometimes and little waste battery .And that ,I don't like the AGNi Controller ,One reason :For users who use other languages, this apk is difficult to translate . But , I can't deny it is a good kernel .
About Other kernel , I did not use them for a long time . So I do not understand.

Battery and performance are undeniably affected by your kernel.
For example, the battery life on Nitrogen OS kernel is amazing, and the reason for that is, reduced performance. It's not slow, it's smooth really, but it's slower than Radon's balanced configuration.
And I think your argument that a kernel can be judged by the number of features, governors and schedulers it includes is wrong, because you don't need multiple governors or schedulers to get a good experience.
At one time, you'll only be using one, and that's why the stock configuration of the kernel matters.

I think every custom kernel has their advantages and disadvantages.
All we need to do is tuning it.
For example, I use Franco kernel and I changed the input boost ms for better responsive.
Or I use nitrogen kernel and tuning the governor for better performance.
However, I choose latest ex kernel manager app to tuning the kernel. It's more friendly ui and more reliable.
And the best thing is latest version of radon/franco/exkernel/nitrogen/agni has unified fp support.

Kernel j510FN

Why after a lot of time there are no custom kernel(oc) for Oreo and why some kernels Wich don't work don t have accurate clock speed are not deleted or banned rooms ..?
Is there any developer who can make kernel for Oreo who know what doing and have accurate clock and proper clock table?????

There are plenty of custom kernels for aosp oreo and yes some of the clock speeds are fake.We don't have oreo TW yet and may never get it.Also phone is nearly 3 years old now and you know the maximum optimal clock speed is no higher than 1400mhz or possibly 1500mhz.The phones hardware limits the possibility of any future kernel being better than what we have.Someone just tested twister kernel and got 41900 on antutu so that oreo kernel is the best in my opinion.You have a choice of at least 5 or 6 oreo kernels alone for aosp so there are plenty.It's just J5 2016 we have not an S9 we just have to accept it is a soc 410 and has limitations.Tons of kernels available from MM to Pie even twister works on pie.I think is a great phone but we cannot get something more kernel wise that is going to make any significance even with real clock speeds.

I'm just asking someone to make kernel who have options to overclock 1400/1500mhz proper clock
And a little oc of GPU for OREO...

people have lives to live.
All you need to know to build it yourself is here, great tutorials from a really nice guy. Very helpful and normally replies to questions in his thread https://forum.xda-developers.com/an...w-to-build-custom-roms-kernel-t3814251/page49

Getting away from oreo there are a couple of TW nougat with real clock speeds.One of them is Leviathan and if you have problems flashing that just unzip it delete the build prop and rezip and flash it.The other one is dragon kernel and as far as I can see it has real clock speeds.With dragon I put f/synch off for better performance and read ahead of 2048.F/synch off gives a gain of 2000-2500 on antutu and risk of data loss is non existant for me.I am using dragon on odyssey and listening to music at full volume for last 3 hours and not a single pause and processing is superb.Dragon will give you at least 50% better battery performance than quasar 1.6.Only problem on dragon is it crashes exkernel gpu so better to use kernel adiutor and it works great.Maybe bulgarian jesus will make an oreo kernel as well.

Yes yes I know Leviathan the real one good kernel....but I need OREO BCS of ask 27 dragon kernel don't have real clocks to?
