Go to gpu section and see if your mini frequency is at 160mhz. If not, put it to 160mhz.

Then go to i/o and put noop for both scheduler or deadline.

If you still have lag. Try to decrease threshold up from 75 to 60% or something else and increase the down differetial frequency a little like from 17 to 20% (gpu)

I'm fine now. I even put mini gpu to 54mhz and up threshold to 40 and down diff to 45. Im seeing thé battery life now.

Still have some lag on scrolling with Facebook ans sometimes xda thread
[Galaxy Note II Original Android Development] fylim:
You can try turning on Force 2D acceleration in Developer options. Seems smoother to me.
[Galaxy Note II Original Android Development] timus911:
Thank you! That helps!

Yes, you were right I'd reduced min frequency to 54,I changed it back to 160. -Some improvement.

Changed I/O Scheduler and the other one from row to noop - Getting better (Though I don't understand how it works, yet. Would like to know more)

Decreased up threshold and increased down differetial - Almost perfect

Thank you very much, that helps a lot. Now that I understand how it works I'll find a perfect setting for my chip soon.

Thank you sir!
[Galaxy Note II Original Android Development] ppn7:
I don't know how it work but i try différents settings like you.

Even if i change the threshold and stay at 54mhz i got laggy animations. At the begins it works great but after some minutes and some apps opened it lags again. Now i try 108mhz
[Galaxy Note II Original Android Development] edwardplus:
Beware changing I/O from row to others (I tried deadline).

It will cause the device to a brick.

(Flash the official rom could fix)
[Galaxy Note II Original Android Development] ppn7:
Are you sure the reason of your brick was deadline i/o? Im using it for now. I'm scared lol
[Galaxy Note II Original Android Development] themichael:
I have tried all io governors for extended periods of time with no issues. I don't think that's the problem.
[Galaxy Note II Original Android Development] ppn7:
For now the best in term of battery life is deadline. Don't tried SiO yet

I also use Greenify and have no trace of lag. Everything default... Could it be your rom?

[Galaxy Note II Original Android Development] darkchazz:
How to fix the lag: switch to devil kernel. All the great Perseus features minus the lag :laugh:

I have tried tweaking everything in stweaks but I could not get Perseus to be as smooth as the stock samsung kernel and other kernels. But it was an improvement though...

What you can do to reduce the lag on Perseus:

Set minimum gpu frequency to 266mhz or keep it at 166mhz and reduce the up threshold so it will boost as soon as you touch the display.

In the memory/internal tab: reduce the sampling rate to ~30000 micro seconds.

The above two are enough for me, but you can also increase the frequency for responsiveness and flexrate max frequency, and decrease the cpu scaling up threshold etc.
[Galaxy Note II Original Android Development] lainemac:
Raise the frequency responsiveness to between 600-800mhz.
[Galaxy Note II Original Android Development] superpuper:
try stock kernel u`r friends will hear the difference
[Galaxy Note II Original Android Development] timus911:
I don't think so, since there was no lag using uneak and terrabuzz.
[Galaxy Note II Original Android Development] ppn7:
The problem is that why we get an Incredible battery life. I reach 9h screen on time only with perseus.

Maybe the undervolt can improve lag freezing??
[Galaxy Note II Original Android Development] Arbalestos:
I posted some settings in this thread a few pages back. These are the same cpu settings the stock kernel uses. Maybe you can get better performance if you try those.
[Galaxy Note II Original Android Development] sshafranko:

[Galaxy Note II Original Android Development] ppn7:
7h and 8/9h with my setting
[Galaxy Note II Original Android Development] leamoor:
Guys, want a good battery life, but also want to have a good performance,in my opinion, it is impossible, it is best to find your own suitable setting!
[Galaxy Note II Original Android Development] sshafranko:
I actually agree with you. I lost about an hour somehow myself but the lag did disappear. Although I installed and set up Greenify app and it looks like I'm getting my hour back and then some.

I guess its tough to have it both ways like mentioned above you have to find a median setting somewhere in between the stock and Perseus settings may be doable.

Your settings worked for me! I wish I could set it the same with FRanco Kernel on my Nexus 7 3G! I took both off charge at the same time this morning...the N7 is at 86% and my Note 2 is at 95%...both with about the same screen on time...
[Galaxy Note II Original Android Development] ppn7:
I have installed ICS animation transitions and it feel better. NO lag i it's look better! I just up the frequency responsiveness to 500mhz and up threshold gpu from 75 to 60.

I'm fine but some lag on scrolling and that i think it's because of the appsand gpu force rendering and maybe deodex rom.
[Galaxy Note II Original Android Development] Arbalestos:
Yes, I think that sounds about right. It's very hard to find the perfect settings for speed AND battery. (If you find some, let me/us know :fingers-crossed: )

But I'd rather sacrifice some battery rather then performance, because the battery of the Note 2 is already large enough.

I usually get 2 days standby and 4-5 hours of screentime, but thats because I mostly have the auto-brightness off and brightness at max when I'm watching videos, browsing or doing other things for longer periods of time. Also alot of my videos can only be played with software decoders, meaning it will use the CPU instead of the GPU to play them, which will increase power usage alot.

Ofcourse you can tweak it however you want, my settings are just a tip ;)

For the rest, thanks for the replies, glad I could help!
[Galaxy Note II Original Android Development] ppn7:
In fact i have only some lag with facebook and when i scrolling with some apps. With your settings it's better. But what i can't stand the lag with JB animations that's why i flashed a zip file for ICS animations and it's really amazing. No more lag when i open oe close apps. Just scrolling lag but i don't care.

I really recommend to flash zip file for having ics animations if you like these.

Quick request, but I didn't read the entire thread so I apologize if this has been made already: support for wifi transmit power modification either through the existing STweaks app (which I love, BTW - amazing level of control and a nice interface) or through the WiFi TX Power app. I have the app and it keeps looking for iwconfig. Thanks for thinking about it!
[Galaxy Note II Original Android Development] iken2010:
First many tnx on great kernel!! :good:

And info if there is a chance to implement a mhl hdmi output option to force 720p? I read they did it for htc one and I think it a big issue for note 2 not having this option because od laggy 1080p 30Hz resolution. I tried with diferent cable combination hdmi/rgb but no help. If anyone knows anything regarding this pls let us know.
[Galaxy Note II Original Android Development] SirCanealot:
AndreiLux either said he's aware of the issue and wants to look into it. Or he said he's looked into it before and there's no easy solution and he doesn't have time to look for a hard solution.

So either way he doesn't have time :p

Hopefully if he does look into it, it will be useful for the whole recent galaxy family :)

Still unable to connect bluetooth HID (mouse mainly).... phone restart on pairing....

For log, I already posted 2 logs regarding this problem... with 2 different sammy ROM version...

And today is the third sammy version (DME1 just updated yesterday), reboot on pairing with mouse.....
[Galaxy Note II Original Android Development] Old faithful:
1) Make sure you have a backup copy of stweaks. I use stweaks profiles.

2) using your root enabled file manager, go to. /data/.perseus

3) delete all the profiles, rename them or move them to a safe place as a backup.

4) Using app manager select stweaks, stop, delete data, uninstall stweaks. Reinstall stweaks from your backup.

5) go to /data/.perseus

A new default.profile has been generated.

6) make a backup copy of the profiles thus generated and keep them in a safe place.

7) BEFORE tweaking, ALWAYS make a backup copy of your active profile before tweaking. NEVER tweak the default profile, it is your reference!

Hope this answers your question!

Hello everyone,

I wanted to say that after several tests, the best modem to use to increase the battery life is the UBMDA1, which also has a really amazing sound and excellent speed Connection. Perseus with 36.3 I finally got a really perfect combination!

[Galaxy Note II Original Android Development] jujuburi:
Hi, I am on A.R.H.D ROM and was using Stock kernel, but today I flashed Perseus and I am noticing severe lags, especially while scrolling! I changed the CPU hotplug settings and locked all the cores to number 4, but that didn't do anything good. Then I changed the governor to Performance and the lag was gone and fluidity came back, but I won't be using it as it will lock the CPU clock speed at max always.

So could anything be done, other than going back to stock kernel?
[Galaxy Note II Original Android Development] edmondt:
Can the next version have a lower CPU min? Like 50MHz?
[Galaxy Note II Original Android Development] iba21:
It's possible, but, why you whould that? 200mhz also has low power consuption
[Galaxy Note II Original Android Development] frankcilo:
In fact, I use min freq set to 500mhz, and i haven't lag and battery is great!
[Galaxy Note II Original Android Development] iba21:
For me 500mhz is too high..

The first issue of having a lower freq is governor has to increase the frequency too times faster..

It means.. is better to have a stable 200mhz than a gap from 50 to 300.. why?

cpu's voltage is not linearry as the frequency.. it takes more time to decrease voltage.. so.. if you have a pure stable voltage at 200mhz is better than a switch from 50mhz voltage and 300.. more time in 300mhz voltage!

Call smb using speakerphone and stock kernel than using perseus, and ask person you calling - is there any difference in quality of sound that he gets. He will tell u that on perseus you sound like from the toilet. And on stock kernel he will get clear sound from you. People here have this issue so what link do u need ?

How to change the DeltaV of illumination?

I'm explaing better.. in some condition i have a too low brith for my use, and, sure, samsung's brit bar is in auto, at top value, so, it's a sensor's "issue".. a too low brit value at that ambient illumination

I know it's possible to change in htc's phone.. i did it with hox, but, not find it here with note2

Any idea?

Is it possible to lock the gpu freq at 108 mhz while the screen is off and have a minimum gpu freq of 266 mhz or 160 mhz while the screen is on...

I'm not a dev but if the screen is off gpu shouldn't be off too? G stands for graphic wright?

If you want that kind of settings you could use Tasker. U can set any gov/freq for cpu (dunno if gpu though) based on state/apps etc.

Edit: Tasker can be used only for CPU settings. Just tested and no GPU tasks available.

Didn't you try it? This is exactly what it should do. Charging and data transfer via USB uses different pins so they should work simultaneously. Is a part of a smartdock MHL actually what this thing does. Perseus is set for MHL and smartdock so it should work.

[Galaxy Note II Original Android Development] Dan Law 001:
I don't know why when I set all the core frequency to max 1.8Ghz, even i didn't lower it, for few minutes the frequency automatically gone down. This is quite frastrating when you are doing some benchmark test such as the Antoutou since I can't never get a accurate result regarding the hardware performance as I can not see the max potential of the performance of the hardware. This bothers also when you are playing video games for not a long time because the graphic quality and smoothness will be then suffered. I have been reporting this problem in the past and people says that it's the safety feature of the kernel that prevent the CPU getting overheated but I can not find this reasonable since even that the CPU is at moderate temperature that is around 40°C, the frequency starts to lower. Therefore, are there any method in order for me to set a higher temperature threshold at which the frequency will lower?

Yeah having same problem.But if u use SetCpu, It will keep it at 1.8

1st is not advise to do overclocks for nothing

2nd benchmark has static calculation witch uses all the core with all his cache.. that situation is IMPOSSIBLE to replicate with standard code.. (y)

3rd benchmark are usefull only to compare some cpu with the same architecture, to understand the difference..

So.. do you have lagghish game? Have you tryed performance governor? :-/

Do you would have the max bencharm valie ever? CortexA9 has an inorder NEON istructions, it means oc is unusefull, an out of order will be better and better at lower frequency

So.. i don't understand why you would overclock.. i'm using my note2 with my governor parameters and, for me is all perfect, pure fluidity, and 4 cores is turned on rarely
