MWAHAHAHAHah this battery life is INSANE.

After a bunch of cpu governor tweaks I am finally attempting to run my phone dead.

I anticipate it will last for 50 hours+

Take a look so far, incredible results

19 hours on battery 17 hours of wifi connected fulltime and a timed autosync with only 35% battery used... lol

thats 25 minutes of data on to accomplish and establish full autosync as opposed to running data straight for the 2 hours that I was not in wifi range.

Juice defender will pulse your autosync, it can be configured to enable auto sync for 15 seconds every 5 minutes, if its downloading it wont stop, once downloading finishes it waits 5 minutes and then again turns on auto sync, this is a huge savings in power consumption, yet you still get every possible notification within 5 mins.
[AT&T Samsung Galaxy Note II] ShadowVlican:
testing some custom UV now... hopefully it'll help with the battery life

i don't bother with Juice defender... i need my instant PUSH for a variety of apps
[AT&T Samsung Galaxy Note II] gundal:
5minutes isnt quick enough of a notification for you? the difference in having it active for 15s every 5mins and full time is huge
[AT&T Samsung Galaxy Note II] ShadowVlican:
how would it affect instant messaging apps like whatsapp or facebook messenger?
[AT&T Samsung Galaxy Note II] ShadowVlican:
using STweaks, setting the governor to Performance locks the device to 800mhz even when i have 1800mhz as max

i don't anything else installed that could alter CPU overclocks

UPDATE: nvm, a reboot fixed this strange behaviour...
[AT&T Samsung Galaxy Note II] gundal:
youd get all of the messages on facebook server every 4mins and 45 seconds.

so like if your friend sent 8 small messages, they would all come in 4 mins and 45seconds from the last time you got messages.

I use text as my main source of instant texting, which runs on the radio and is always connected, otherwise you couldnt get calls lol

But I see your point its not really instant messaging anymore, as for email and facebook notifications and other synced things, I dont really care to know the VERY second i get an email, within 5 mins is fine with me.

I'm running (N7105XXDLK7 4.1.2 International Stock ROM for i317 and i317M) port.

Should I use the ATT Perseus kernel contained in this thread or International version of kernel?

Thanks
[AT&T Samsung Galaxy Note II] gundal:
I just tried to reproduce this and it it did not occur for me.

performance governor pinned the cpu at 1800 for me.

---------- Post added at 03:58 AM ---------- Previous post was at 03:57 AM ----------

Yes. the one in this thread with i317 in the title of the .zip

i317.is your model thats what you want to flash

If you flash an international kernel, your phone will boot and work fine except you will not be able to read the simcard or have access to the phones radio.
[AT&T Samsung Galaxy Note II] ShadowVlican:
Yea strange.. After a reboot, it's back to how it's supposed to function
[AT&T Samsung Galaxy Note II] starche_old:
thanks for help, buddy :) But I think I'll try it first by myself :-;

here's my voltages. Nothing crazy (I spent an hour only on that) and I'm pretty sure it got a lot of room for improvement. I used gundal's numbers + a bit of my "tweaks"

Freq (MHz) - Voltage (mV)

1800 - 1250

1704 - 1225

1600 - 1150

1500 - 1125

1400 - 1050

1300 - 1025

1200 - 1000

1100 - 1000

1000 - 975

900 - 950

800 - 912.5

700 - 887.5

600 - 862.5

500 - 850

400 - 825

300 - 800

200 - 775

Again, nothing crazy - my CPU cannot handle 750 @200 - reboots instantly. But I've got 1250 @1800 and my gut tells me - I can go further down.

About STweaks. All in all - great app, where I can OC CPU, GPU as well as fine tune the system further. That's fantastic. Couple of comments on it though:

1. It's hard to believe, but there's no profiles at all, nor for CPU nor GPU. That's weird - should I input the whole bunch of numbers both for CPU and GPU? Why not to have profiles, where I can save all that? Convenience is one thing, but we avoiding problem (see #2).

2. Bootloop. What I suppose to do? Like flash script in CWM to clean voltages in NSTools. Kinda handy :)

3. "Nice to have" - "+" and "-" buttons besides slider. Kinda hard with my hands to lift the finger fast enough not to move voltage slider a step up or down. With buttons it's not a problem, one click and I'm done.

4. First time starting STweaks somewhat 50/50 FC happens to me. Second start is OK 100%.

5. Where I can change scheduler?

Again - perfect app

just noticed there's a v27.4 now, whats different from the 27.3 that was put up earlier that i grabbed? thanx
[AT&T Samsung Galaxy Note II] lude219:
do I have to use STweaks with this kernel or can I use another one? Will there be any side-effects for using another tuner other than STweaks?
[AT&T Samsung Galaxy Note II] ElAguila:
Has anybody else had gpu issues after flashing the new kernel. I did a backup then flashed the new kernel. When I booted up the phone it froze when trying to unlock and then the screen became fuzzy and pixelated and the screen shutoff. I pulled the battery and flashed back to 26.1 and everything was fine. I am trying to find out what caused it so I can hopefully get 27.4 back on as I have each kernel to be a little better than the previous one when it comes to battery life and overall performance.
[AT&T Samsung Galaxy Note II] P1 Wookie:
Did you have it overclocked or undervolted at all? I've had no problems with the new kernel.
[AT&T Samsung Galaxy Note II] starche_old:
Very true ;) I'm keep forgetting about it all the time...
[AT&T Samsung Galaxy Note II] ElAguila:
I had a script to run at boot to set the gpu max at 640. I flashed the previous kernel and set the script not to run at boot. Then I tried it again. It ran fine and I was able to execute the script. It only had an issue when I set the script to run at boot.
[AT&T Samsung Galaxy Note II] Goatblaster:
Loving the audio tweaks btw, thanks! Always found I couldn't amp the volume up enough on headphones, the headphone amplifier is certainly nice, along with the stereo expansion! Sounds AWESOME. :good:

Undervolted 50 across the board, anything more crashes, but haven't tested all frequency steps yet, haven't had the time. Stable at -50 for me on all at least, up to 1.8ghz.

yeehaw!
[AT&T Samsung Galaxy Note II] P1 Wookie:
Glad you got it working. I know from experience that my Nexus 7 doesn't like the GPU oc'd much, and had artifacting on home screens and such, so I figured it was probably related to that.
[AT&T Samsung Galaxy Note II] ElAguila:
I am not sure why the script hangs it when it is set to run at boot but not when I manually run it. Oh well it isn't big thing now that I have it figured out. Also just to make sure it isn't anything on my end. When you flash this kernel you no longer have a custom boot screen, right?
[AT&T Samsung Galaxy Note II] JrkSoldierX:
Long time lurker of xda, just made an account. No idea why it took me years to do, just lazy i guess, and now i want to get involved in the community :cool:. I just got my note 2 on ATT, rooted obviously lol, using twrp, jedi x3.3 rom with perseus 27.4. Before my note 2 i used the original htc evo on sprint. On my evo i rocking cm7 with the SavagedZen kernel. With SavagedZen on my evo i always had 2 options when flashing the kernel, Completely Fair Scheduler or the Brain **** Scheduler. After using both i found the Brain **** Scheduler always more stable with better batter life. Do you plan on bringing the Brain **** Scheduler to perseus? Would it benefit the note 2? In setcpu i only see: Completely Fair Scheduler, noop, deadline and sio? I have no idea what the last 3 are. If someone could fill me in i would be most grateful. :good:

If I go down to even 1237.5 on 1800 I crash in antutu 1250 is my lowest :/ guess i dont have one of the best chips
[AT&T Samsung Galaxy Note II] starche_old:
I did not checked it in antitu, I used NFS MW for that. 3-4 races on each freq - just to make sure.

Your doing way better then me on lower freq, which is more important. I'm lucky on higher freqs, you - on lower ones ;). Don't worry, my friend, ce la vie ;)
[AT&T Samsung Galaxy Note II] turilo:
How would I go by trying this on my note 2? Care to share the actual script? :D
[AT&T Samsung Galaxy Note II] gundal:
you can either apply them manualy in stweaks or setcpu or he can make u a script..but i assume he used stweaks and doesnt have one, or could upload your /data/.persues/action.profile that holds ur changes

[AT&T Samsung Galaxy Note II] ahmarchi:
here a little antutu score i have with new perseus. i can probably increase it a little bit more, but i think it is perfect and stable. i ran a few different times, and its weird, the gpu processor at 640 gets higher scorer than at 800. right now i am using 1800, and gpu at 640

here are the voltages i use on cpu and gpu. along with a pic of antutu.

hope this helps you guys some. with this set up, i used it last night for a few hours at the bar etc, went to sleep, and after 7 hours and 30 min i went from 100% to 94%
[AT&T Samsung Galaxy Note II] gundal:
The gpu did worse above 640 because your chip can't handle higher freqs. Try need for speed at 800 it will crash our have artifacts
[AT&T Samsung Galaxy Note II] turilo:
I applied these settings also, so far so good :D 100mhz lower score in antutu than what u got but that's OK :D ty
[AT&T Samsung Galaxy Note II] starche_old:
I'll strongly recommend "DIYing", i.e. find freqs/voltages which are for your CPU. Don't get me wrong, buddy, I'm not trying to push you, all I'm to do is to help you. All CPUs are different and yours might do way better then these voltages, but you'll never know this until you'll try, right. The same thing if you're CPU needs more vintage then these numbers. You'll end up with crashes.

Anyways, try it. I can tell us how to do so ;)
[AT&T Samsung Galaxy Note II] andronikal659:
This is an awesome kernel. However, I can't detect my usb connected to my pc anymore. I'm on Jedi rom 3.3 and I think it use to work over stock Rom. Now I can only use PTP not MTP. Any fix I can do?
[AT&T Samsung Galaxy Note II] Jonnyredcorn:
I've been running stock kernel since I've gotten the phone and I've had pretty execellent battery life and performance. If theres nothing wrong, don't break it....well I want to try Perseus. Anything supported by stock kernel that I lose with Perseus?
[AT&T Samsung Galaxy Note II] ShadowVlican:

[TOOL] Recover from an stweaks bootloop

HERE YOU GO

If you accidentally set your voltage too low and have set on boot checked and are stuck in a boot loop.

If you're like me you found out the hard way, it applies those settings very early, like right after you begin the boot animation.

So its impossible to fix without a computer, and knowledge of the filesystem or a nandroid backup, but F that.

Just flash this through CWM and your good to go puts back the stock settings.

Also included another one that will do a one flash overclock gpu from 160-640 and cpu from 200-1800, while also undervolting.

I took my normal undervolt values and increased them by 50ish so everyone should be able to run these.

For people who dont understand dont worry, it will just work for you and save you battery.

For people who do, write down your voltages, so you can set them accordingly later.

If you go into STWEAKS under GPU youll see I added in 400mhz, 600mhz, and 700mhz for people who might have better or worse chips then me and cant go as high. (I crap out after 640 with Need for Speed)

(EDIT actually STWEAKS cant change the frequencies on boot (just yet, its coming) for now you have to run a script to add in those others one,

Also appears to be a bug where STWEAKS cant change voltages on boot either.Andrei?

EDIT 2 (Ive included my script in the flashable overclock zip) (to use it just goto rom toolbox(market), click scripter > click the plus and then import the script is called 'gpu_160_640' and its on the first screen you look at after hitting import, just scroll down and select it.

after that click the script you jus adfded and hit run script, if your system is stable click it and use the set at boot option, then bam cpu and gpu overclocked and undervolted.

***Please Note***

It will take longer to boot (the first time) it has to rebuild the profile or something lol.

IF THIS SCRIPT MAKES YOUR DEVICE BOOTLOOP THEN YOUR DEVICE HAS A ****TY CHIP AND YOURE SCREWED...lol jk flash the default one and you will be back in action.

For people who have already done their voltages and are stable... Have you watched your CPU? do you feel it goes up to aggressively? I found mine at 1800 all time time so the overclock zip also includes my governor tweaks.

Thanks to Andrei for pointing me in the right direction for which files store the data stweaks generates and executes.

and telling me to make this lol.
[AT&T Samsung Galaxy Note II] P1 Wookie:
Your settings have always seemed to work well with mine, so I'll roll with it!
[AT&T Samsung Galaxy Note II] gundal:
Just for you.

Heres my ACTUAL one that I use if i need to recover, (its the overclocked one with my true voltages not upped to have a higher success rate)
[AT&T Samsung Galaxy Note II] ShadowVlican:
thanks, that's awesome

OP should definitely link to this so it doesn't get lost in the future

wish i had this earlier... i was stuck in bootloop so i had to completely wipe and reflash rom/kernel (installing another kernel or using titanium backup didn't get rid of stweaks and its settings, so whenever i reinstalled Peseus it would bootloop no matter what)
[AT&T Samsung Galaxy Note II] gundal:
yea none of the data is stored in the files the kernel flashes (by design, so upgrading doesnt overwride settings)

and none of the data is stored in the apk data either.

its all about /data/.perseus

Im fairly sure OP will link this, hes asleep atm.

Of You flashed the latest kernel, it should of installed STweaks app. That has everything in it for you to tune the kernal with extras.
[AT&T Samsung Galaxy Note II] ryvandal:
thank you for the super quick reply I did not notice that app! Could someone send me a link to optimizing this stweaks app for best battery life? It'd be awesome I am a little new to this and would love to learn!
[AT&T Samsung Galaxy Note II] gundal:
Yes, these are not the ideal solution, it would be best to retain your own settings and just override the set on boot part, but that will come next kernel release from andrei, for now these are a super temporary way to get out of boot loop

PLEASE NOTE

they will erase all your current stweaks settings and either put back tghe note II stock ones or the settings I use, depending on the zip.

IF YOU DO WANT TO RETAIN YOUR SETTINGS

Make a copy of /data/.perseus

copy it and call it .perseus2

then after using this zip to get back out of a boot loop you can rename the .perseus2 to 1 and be able to see your settings and make changes

(will have to reopen stweaks)

Something funny going on with battery life. Going to run battery stats and report back. My phone dropped from 98% to 66% just Sitting on my desk for for 4 hours.
[AT&T Samsung Galaxy Note II] gundal:
yea check wakelocks, likely you had something running, for example. if you open need for speed and start a race and hit home to get back and sent a text then turn screen off.

Need for speed is still playing its audio (even tho its not actually playing it to the user) and that makes the cpu stay awake to process that, you'll see a partial wakelock for audio_out. which prevents the cpu from hitting deep sleep and runs your battery down.

nah haven't tried older kernel version.

All kernels , mods etc were lost on sd card after flashing CleanRom-M

card became corrupted.

Anyway if you wouldn't mind hooking me up with 26 that would be great.

I extracted 26 from Cleanrom2.1 flashed all works well

Update;

Well not so well lol , System UI just crashed.

Yeah did wipes etc on install , its a code I live by.

I'm thinking compatibility issue on my original rom install was due to rocky flash , On boot up my SD card got corrupted had to reformat.

A couple hours ago I did another Clean3.0.1 rom install / flashed PK27 & everything's running smooth now.

[AT&T Samsung Galaxy Note II] BKO Overdrive:
Not sure if its a huge issue, or if its one in general. Im glad now we can use STweaks instead of running scripts, makes it more streamlined. I currently have zero scripts running and i have my own OC/UV settings for the GPU/CPU set. Now what im curious about is the GPU Voltage settings, when i go to sys/devices/system/gpu/volt_table. When i look at the values they do not match the ones set in STweaks. But the max freq file is at 800 running zero scripts so i know steaks is working. Im still slighty new at this. Is that file only there to show you the defaults? Or should that file be changed to refelct the settings from STweaks?

Edit: I confirmed the cpu volt table matches what STweaks is using, everything is sticking except the GPU Voltages

Edit2: I also noticed the Default voltages in the volttable file are diffrent than the defaults in STweaks, but i think i read somewhere in the OP it was a issue getting corrected. Matter of fact i just looked at it again and he did make a note of that, so no issue there. I guess its the gpu voltages now.
