Sorry. I got a noob question here. I am amazed at the great battery life u guys are getting with this kernel and script. I was wondering if this kernel and script can be used on stock rom with anu problems? Currently i am using synergy with stock and i am loving it with battery life being adequate. But being greedy, i want more so i am looking into trying this kernel. So can ppl give me their feedback with this kernel & script and stock rom. And last question, if i am not a fan and want to go back to synergy can i use my nandroid backup and restore my previously saved synergy setup and that would get rid and the kernel and script?

Thanks for the help
[T-Mobile Samsung Galaxy S II SGH-T989] hinghing1113:
I have a question. the ultimate version eat more battery then the mainline, right?

any idea how much more the ultimate eat approximately?
[T-Mobile Samsung Galaxy S II SGH-T989] SwervFusion:
1) Yes

2) You really should just flash them both and test. Your usage will be different than anyone can accurately tell you.
[T-Mobile Samsung Galaxy S II SGH-T989] SwervFusion:
Sorry..i dont use stock rom..but to answer your last question. Yes, you can simpily restore your nandroid backup and it will return your rom and kernal back to how it was before you flashed.

You can't edit the file on your phone, i tried with a few different apps with no results. The script file is read only, and can't be changed to read/write
[T-Mobile Samsung Galaxy S II SGH-T989] jRi0T68:
I edited on my phone. Extract with root explorer, open script with text editor, edit, save file. Then in root explorer, copy script, and paste it over the one still inside the zip file.

After flashing to DEWIZZED, CPU1 properly sleeps. BeastMOD + Faux is not a good combination to flash.
[T-Mobile Samsung Galaxy S II SGH-T989] 850T5m:
Lol good idea, i was trying to edit the file in the Android system, in the root directory...i guess we can unzip the script and edit it this way. Thanks
[T-Mobile Samsung Galaxy S II SGH-T989] BIGWORM:
After flashing Dewizzed and 7r2, System Tuner Pro is telling me that CPU1 is not sleeping. Can anyone confirm?
[T-Mobile Samsung Galaxy S II SGH-T989] darkamikaze:
I'm UV -100 at 1.5MAX and 384MIN using On Demand :/ (7r2)

I can not get a similar battery life to synergy.. Hopefully the more updates come the better it is for me :O..

something in sleep just eats my battery..

maybe it's cause i was using smartassv2 on synergy? then I hear it's not really optimized for our phone yet.. so i dunno what it is :o
[T-Mobile Samsung Galaxy S II SGH-T989] Teo032:
Alright guys I did some experimenting with the undervolting

Problem: undervolting and mhl connector conflicts

when using gideon's VM script -75mv I noticed when connecting with the mhl connector (monoprice) there was a slight lag and my tv had these quick flashes of blue screen (about half screen). I realize it happens when it is rendering graphics of some sort. So I tested by playing games, fruit ninja, I could determine the lag by the slices. Now when i remove the mhl connector, the phone is back to normal speed. I flashed gideon stock script and everything was normal, therefore, it has to be one of the two variables or both (UV/OC).

FIX: Long story short. it turns out it was the UV... at -50 is no good still. but at -25 it is smooth without any flashes and minimal lag with mhl connector, this is at 918Mhz (amazing).

So whoever plugs their phones to the tv and you're having problems.. its because of undervolting.

I know this is FAUX's kernels thread and this probably should have a thread of its own, but I noticed it when using Gideon's script with faux kernel so do what you will with it.

remember each phones are different so maybe your UV varies or the mhl connector varies.

edit: I wanted to add (because someone was asking), you can change gideon's script on the phone without flashing again.. i use es file explorer to do it (root explorer didn't let me), just go to the location on the phone.

[T-Mobile Samsung Galaxy S II SGH-T989] Simer03:
so do we edit within the init.qcom.post.boot.sh file??? when i edit the file and try to copy it into the zip file, it wont replace it, it only puts it next to the zip file.... help? using root explorer? I have a mac so i cant edit .zip files easy like windows people :/

edit: i extracted the entire zip file, then placed the edited file in the right folder, then i long pressed the whole extracted folder and made it into a zip file, then flashed, and it flashed correctly....we'll see if it worked

edit2: opened fauxclock and the settings didnt stick....or maybe im just doing it wrong

Try both, form your own conclusion. Keep in mind, what works for someone else may not work for you. The only way to really know how your own handset will perform is to try everything.

[T-Mobile Samsung Galaxy S II SGH-T989] mettleh3d:
Gideon, in your script, what happens if you dont match the max mins of CPU0 and CPU1? ie:

384/918

384/1512

What about governors?
[T-Mobile Samsung Galaxy S II SGH-T989] sdemmitt79:
GideonX

Is it possible to adjust the voltage for individual frequencies instead of globally with your script?

And if so would you be so kind to explain how.

I have been using system tuner and managed to tweak certain frequencies to work at lower voltages, but I would rather just add it to your script and not have to use an app.
[T-Mobile Samsung Galaxy S II SGH-T989] darkamikaze:
The first post shows you how you can make a CPU voltage table.
[T-Mobile Samsung Galaxy S II SGH-T989] sdemmitt79:
I totally overlooked that

Thank you
[T-Mobile Samsung Galaxy S II SGH-T989] GideonX:
I assume it'll set the two cores differently. I never bothered trying it tho.

Here's the format for individual voltages:

echo "speed voltage" > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels
[T-Mobile Samsung Galaxy S II SGH-T989] vomer:
Hey GideonX, just wondering if your script is universal to all phones? If not how can we modify it so it can be used on other android devices. Thanks.
[T-Mobile Samsung Galaxy S II SGH-T989] mettleh3d:
-75mv

CPU0

384/1512

CPU1

384/918

uh, it didn't work out all that well. All i changed was 1512000 for CPU0 and flashed that zip. The phone booted, but there was stuttering, some hot boots, (about every 5-10 mins) and it didn't deep sleep even with the screen off for several minutes. I want to try again, perhaps the -75uv @ 918MHz was the issue; I know that setting didn't play very nice with me.

If successful, the trade would seem very beneficial, fast and fluid full-time CPU, and a less taxing, battery sipping 2nd CPU.

-------------------------------------------------------------------------------------

Edit: changed global voltage to -50mv and everything is running candy dandy. 1 hour in, no reboots, deep sleeping like a baby. Setting different clocks method seems to work.
[T-Mobile Samsung Galaxy S II SGH-T989] GideonX:
It probably won't work for other devices aside from the Skyrocket and Hercules.

[T-Mobile Samsung Galaxy S II SGH-T989] Teo032:
from the looks of it, your display has been on for quite a bit. Check your Display on time. It should last around 3 1/2 hr on average, give or take 15 mins, off a full charge.

yes this device can go a little over 4 hours, but it depends on your settings and whats running.

i haven't tried many roms yet.. just jugs and dewizzed, but dewizzed gives me almost an hour more.

edit: actually thats an inaccurate comparison, i just realized i got a new device (a white one) and i restored a nandroid from my other one so the batterystats needs to be wiped.

Wiping batterystats does not improve your battery life

Hey gideon does your script stick at boot?
[T-Mobile Samsung Galaxy S II SGH-T989] jay661972:
its the script and should be stick at boot. G's script is way better than faux app or systme tuner. I am averaging 20hrs with minimal use but I am running stock rooted rom, no custom rom for me at this moment until miui starts porting to our phone, tmo sgs2
[T-Mobile Samsung Galaxy S II SGH-T989] PJcastaldo:
I agree the script seems to use a bit less battery for some, for me at least its kinda not as good as the apps like fauxclock because to make changes you need to flash a script.

Example: if I am saving battery i might be underclocked to 800mhz but i may want or need to jump up to 1.5 or so for more taxing tasks or heavy graphic games.

Dont get be wrong, I appreciate the script, but yesterday I got 14+ hours with more than 3 hours of screen on time, 40 minutes of navigation, I played Shadow Gun and adrenaline HD, and several texts and phone calls using fauxclock overclocked @ 1.5ghz and undervolted -75.

Honestly I love this kernel, i am using the ultimate version on Juggernaut 4.1
[T-Mobile Samsung Galaxy S II SGH-T989] jay661972:
i dont think you need to flash script to make changes, as long you have root explorer app, you can change it using root explorer all the time and reboot that's it. I agree that faux kernel is the best. using that kerenl to my sensation.
[T-Mobile Samsung Galaxy S II SGH-T989] GideonX:
Sure does.

That's actually what I do when I'm testing. The flash zips are just there for first time go around.
[T-Mobile Samsung Galaxy S II SGH-T989] PJcastaldo:
Point being thats still twice as long as just opening an app and moving a slider.

but what ever floats your boat as they say.
[T-Mobile Samsung Galaxy S II SGH-T989] GideonX:
Terminal emulator also works for instant changes :)

Teach me please?
[T-Mobile Samsung Galaxy S II SGH-T989] mettleh3d:
Me too, Im not always near a PC with notepad++
[T-Mobile Samsung Galaxy S II SGH-T989] GideonX:
Sure, here we go.

To set any of the settings you wish (min, max, gov, etc.) you can perform this via terminal emulator. For example, let's say you want to change the min frequency for cpu0 to 192Mhz. You would copy from the post boot script and paste into terminal emulator:

su
echo 192000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

Hit enter and your new min is set. Now if you reboot, you lose this setting and it will revert back to whatever is saved in your post boot script.

All the cpu settings in the post boot script I added can be done on-the-fly via terminal emulator. The script itself is just there to preserve it on every boot with settings you've entered. Anything you do on terminal emulator will override that, until the next boot.

I hope that makes sense.

Happy copying/pasting :)

[T-Mobile Samsung Galaxy S II SGH-T989] mettleh3d:
So here's a script I gave a try, thanks to faux and gideonX of course!

I set up the script with:

CPU0 384min/1512max

CPU1 384min/918max

ondemand, -62.5mv globally undervolted.

No reboots all day, 4G on 95% of the day, wifi on sparingly, deep sleeps instantly,very conservative drain when idle. Not too bad. The purpose was to have a fully fluid and fast main CPU and for the 2nd to sip battery when it was needed.

Hey GideonX

There's a problem with your new script. I had it for a week, at 1.5ghz and -37.5mv, lagfree

Worked perfectly with juggernaut, i just noticed a problem tho! If I'm listening to music and then launch a game, the game will force close. Your other script doesn't do this.

An example would be using PowerAmp for music, and playing unblockme, it will force close.
