Yes, The DarkKnight is rising again

Hi Dharam,
I'm on Checkrom V7 and wait for a DarkKnight LQ5 Kernel
Do they really stop developing for SG2?

I think they really stopped,leomar wrote "no more s2 developing" on CR forum ,so...

can anyone recommend a governor best suited for heavy use? smartassv2 doesn't really handle resource-intensive apps very well.

Hi,
i wanted to thank you for this fantastic Kernel.
Using it ont CM9 RC2.
I'm coming from Siyah, and Fluxi, but your Kernel just blows everything away. Best Battery Life of all.
And with the upcoming fixes, especially BLN, it will be even better! Good Luck with your exams! And keep up this Good work.
Adding some Screenshots of my Battery Stats, and still 30% left(kernel default settings):
Edit: Added 2 new Screenshots, resulting in a Screen-On-Time with 5h 11m. I'm very happy with that.

Hi i use siyah with miui i want to install asnet and darkknight!
I like to know if darkkn. is for battery saving or / and preformance ?
I like to play gtaIII and other games so preformance and stability is important anny one has exp. or a tip ? tanks

First try the default settings. If they are not good for your usage, you can try to overclock to 1200 and to change governor to ondemand or pegasusq..
Inviato dal mio GT-I9100 con Tapatalk 2

This was my first full cycle with DarkKnight v1.9.2, and the SensatioN ROM 3.5. And these are my results.
On the phone i was basically using chrome and whatsapp. I have no widgets on my homescreen and used the default kernel settings without changing anything. Note that i have a different non-samsung battery from "anker" with 1900mAh.
I think these are pretty decent results for the first cycle so keep up the good work
Ill continue to test your kernel, maybe also with different roms like cm9 rc2.

This is another one of my longest screen on time. The uptime is just 7hrs+ tho, I think.
Ondemand & sio
Auto Brightness
200-800mhz

Hey, i can't post in the development section, so i'm asking in this thread:
flashed 1.9.2 today and can't disable the LEDs. if i disable them in the system settings they stay disabled as long as i don't lock the screen. after unlocking they are enabled again. hadn't that problem with 1.8.
cache and dalvik already wiped.
any suggestions?

How do you guys get such great battery with high screen time? I have brightness set to auto. Whenever I have the screen on I can see my battery % drop very quickly.

How will a custom kernel benefit me

What will a custom kernel do for me. I have been thinking about rooting but I do not want to flash a ROM. I am really loving stock. How will a kernel benefit me. I heard they have something to do with battery. How is that?

With a custom kernel you can do some really cool tinkering for example
- underclock (save battery)
-undervolt ( MAY save battery , but will def help with heat)
- change governor ( may help battery)
- change screen properties . I.e colours
- GPU over clock / under clock ( obvious)
Other cool performance tweaks as well

I'd go with franco's kernel for now.
All of them are new and may have bugs, but franco is a longtime kernel developer and he's the least likely to do stupid stuff or claim features that actually hurt performance or are just placebos.

Franco's kernels seem good. I use it on my N7, but I just wouldn't use it yet as he's working blind. Faux has some amazing battery saving kernels. Mathkid's kernels pretty well as well, I used to use his on the Nexus S back in the day.

I'd be careful about recommending a kernel where the developer is doing so blindly. Honestly its very irresponsible. Unless he's got a device that's 99.9% identical, i cant recommended it.

Under clock can be done on a stock kernel just needs root. Custom kernel allows over clock doubt its needed though CPU is fast enough.
Different governors can be used on stock too but custom kernels may offer extra ones like smartass etc.
They may also add things like NTFS cifs run etc not available in stock.
Using Motleys kernel just now too soon to comment on improvements.
Sent from my Nexus 4 using Tapatalk 2

If stock is working for you, there's no reason to flash another, unless you have the itch.
The stock kernel is great, and undervolting is more trouble than it's worth if you're starting from scratch, unless tinkering with voltages is your thing, and there's zero need to overclock the N4 CPU or GPU IMO. There aren't a ton of options, yet, either. 3.4 is pretty young yet.

As someone who is using Franco's kernel at the moment, I can recommend it strongly. It's running very well :good:

Agree. Franco is amazing and once he actually has the device he will only improve.

Yeah -- that was my other experience, I'm using franco's kernel and have been since day one.
Quite stable at least so far, no crazy changes.

[Q] Which is the best kernel?

What is the best kernel overall?
The best kernel for battery improvement?
Best kernel for performance?
and the best kernel for gaming?
.....and GO!

Stock.
Sent from my Nexus 7 using xda premium

Based on my experience. For overall excellent gaming performance with good enough battery performance, I suggest M-Kernel a25 or a27. And to over clock your device after installing the kernel, use Trickster Mod from play store.

[GUIDE] *NEW* 4.2.1 RESULTS! N7 'Best' Kernel? (Performance & Battery Tests)
http://forum.xda-developers.com/showthread.php?p=31620793

theres no best kernel, they are all good. theres only whats best for your and your devices needs. evrybody is going to say that the best kernel is the one that they use, no one is going to say that they use the worst.

Well I base it on most popular. If its popular it means its good and works most of the time. Maybe I should've used better wording?

popular doesnt mean good. try out a few, find what your device likes. every device is different and reacts differently with each kernel.

Yes you can read there, OP just updated the score. If you want to try, try trinity for best performance, m kernel for best overall. I'm using Mkernel now, really good kernel. No problem so far.
Sent from my Nexus 7 using xda premium

I get about 10-11ish hours "screen on" with light use on franco kernel #38

Motley kernel

i tried
Motley kernel,
Franco kernel
Trinity Kernel
Trinity is the fastest if you tweak it good..
but on the downside the most glitch..
but Morfic just released two updates in two days...
so theyre fixing it.
So im back with Trinity Kernel.
Its good..
and the only Kernel i find that you can change GPU speed, ofcourse Using
the glitchy Trinity Toolbox

I love Franco.Kernel R31. Battery life is great and performance is good as well. R38 is the newest and great, but I feel performance is a bit lacking on 38.

Is it worth flashing a new kernel?

Hi guys, I've recently rooted my i9505, and after trying a few ROMs I've settled on BlackBox. I've never flashed a new kernel before, just stayed with whatever came with the rom, so would it make much difference if I did, and if so, what would people recommend and why?
Thanks in advance.
Sent from my GT-I9505 using XDA Premium 4 mobile app

No probably it won't matter much. Sure there can be a minor difference in your situation, but there is no better kernel.
Some kernels are better optimized than the Samsung stock kernel, but between custom kernels there is not much difference. If you don't understand what the difference is between each kernel, just stay with the one that comes with your rom.

Sound advice, thanks.
Sent from my GT-I9505 using XDA Premium 4 mobile app

no mean to offense anyone...
it is like buying something new to replace a good that you have already (and it is working).
you will have to go and check what custom kernels can give you, to see if it raises an eyebrow. from my experience, each kernel has its ups and downs (I did not find a perfect one). you have to try yourself. a kernel that was best for me might be bad for you, depending on what you expect and want.
there are LOTS of benefits a customer kernel can bring!

Hi mate !
The kernel for instance can offer much customization if you're already rooted and on a custom rom, you can change the amplification of the headphone and the speaker of your device, you can overclock / undervolt your device, you can change screen display settings, you can change the i/o scheduler to your personal liking ...etc and much more !
That's why users recommend it, because it can offer what stock kernel can't and won't offer you .

Just in case anyone's interested, I flashed Adam kernel the other day and it didn't really work out. The phone became very juttery and laggy, and I the end I had to restore a nandroid. Glad I gave it a go though.

which is the Best rom for samsung galaxy s4 2017?

Hello, This is my first time. when I search roms i find to many roms and I dont know which is good and stable. so I would like to know which is the best rom for my samsung galaxy s4 i9500.
its should have the original camera application.
better battery life.
and no over heating when using!
overall it should be good and stable rom.
pls provide the names and links below
thanks in advance.

There's no such named the best ROM. Every ROMs have their own advantages/disadvantages. If you want stock camera, go with TouchWiz ROMs.

Kras.

Then go with any TouchWiz ROMs you like. Heating on S4 i9500 is pretty normal on most of ROMs.

suggest a few roms pls!, with link

For S4 to not get hot, I have tried many different roms and options. The ones that did it for me were to use Kernel Adiutor and underclock from 1890 to 1458 or 1242 if I don`t game that much. And regarding battery, if you want to last while not doing stuff with it, go with Row, in combination with any other Governor. If you want performance go with Interactive/ Ondemand and Cfq. But there is no need to leave the phone clocked to 1890 like default cuz it will get hot, especially when you are going to use it with the charger plugged in.
