This is probably a stupid question but can I flash the ramdisk over AOSP kernels as well?

---------- Post added at 08:14 PM ---------- Previous post was at 07:47 PM ----------

Nvm. It was a stupid question.
[Sprint Samsung Galaxy S III] techdog:
I have to say that for my phone killjoy actually increased my perceived lag. This latest version of the TW 4.3 kernel is very responsive on my phone.

I am loving it!

Thanks!

[Sprint Samsung Galaxy S III] marcran75:
Did you go through the steps of activating entropy and boost mods? My phone is running buttery smooth since I installed KJ.
[Sprint Samsung Galaxy S III] techdog:
I just activated boost in aggressive mode and that seems to be working pretty well, although I'm not sure that it is any faster than dkp without killjoy. Probably keep testing with it just to see.

[MENTION=4932679]decimalman[/MENTION] - Have you had a chance to look at the tweaks in killjoy? Do they conflict with any of your own kernel tweaks?

Thanks.
[Sprint Samsung Galaxy S III] marcran75:
Idk if this is related to the kernel or not but I've used the last 5 updates of dkp tw 4.3 and with all of them I was having issues with my web browser freezing almost to the point of being unusable. KJ seems to have cleared this up for me. [MENTION=4932679]decimalman[/MENTION]. .I'm still trying to learn as much as I can so any input you could provide would be greatly appreciated.
[Sprint Samsung Galaxy S III] Visionikz03:
[MENTION=4932679]decimalman[/MENTION] you definitely killed it with this kernel... I am running 54 mHz slightly overvolted and I am getting crazy battery life! Stable as can be! Thank you for your hard work to make our Android experience better! :good:
[Sprint Samsung Galaxy S III] ryandubbz:
What's your other settings? Max voltage? Governors? IO scheduler? IO CONTROL, mp decision, gpu governor and setting?
[Sprint Samsung Galaxy S III] ryandubbz:
I recommend donating for this awesome kernel and also to trickster for an awesome App and to unlock more features. I am currently running MOAR 7.0.1MK3 with the latest dkp 12.26 release along with killjoy and viper. I am having the best battery life I have ever seen and buttery smooth performance. My current settings are SIO scheduler with freelunch governor I don't know what to change the settings so so I leave them at default as it's been working great so far. I have under volted by -50 across the board and lowered my min to 54mhz and max is lowered to 1188mz I have frequency lock enabled as well as zram I have also lowered my max gpu setting from 400 to 200 and kept it at on demand. I have not lost any performance by doing this. My phone is running smooth and is cold battery to the touch. If anyone has any suggestions for better scheduler and the settings for them I'm all ears but so far this has been the cats meow. I will try to lower my volts even lower thanks for all your hard work.

Donation Transaction ID:35938363HM266794N

Edit I am now minus 100 volts across the board and stable :)
[Sprint Samsung Galaxy S III] decimalman:
[MENTION=4835462]ryandubbz[/MENTION]: Thanks! I'll get you added to the OP shortly. :good:

I haven't really looked into what exactly KJ does, so I'm not sure. I wouldn't expect anything to cause problems. It sounds like it contains entropy tweaks, which won't accomplish anything on dkp (but shouldn't hurt anything either).

I'm guessing that KJ cleans out /system/etc/init.d (which is a reasonable thing to do, since lots of ROMs ship with scripts that could conflict with it) and removes the script that dkp uses to lower the processor voltage limits. The vmin zip in the OP also removes that script, and would probably have the same effect. The lowered voltage limit allows for more aggressive undervolting (which is why it's the default), but can cause instability and weirdness (which is why the vmin zip exists).
[Sprint Samsung Galaxy S III] ryandubbz:
Doesn't raising voltages cause more battery drain?
[Sprint Samsung Galaxy S III] glcK23:
Yes but for some people (placebo), it just so happens to increase it lol......
[Sprint Samsung Galaxy S III] decimalman:
Depends who you ask. According to your high school physics textbook, increasing voltages will increase energy consumption. It turns out that processor designers are surprisingly good at defeating physics, so increased voltages don't have as dramatic an effect as you'd expect.

In any case, if it's necessary to increase voltages in order to keep the processor stable (dkp uses lowered, potentially unstable voltages by default), then there's no point in comparing energy usage. ;)
[Sprint Samsung Galaxy S III] ReapersDeath:
I must say.. The 12/26 version is insanely good along the lines of stability and consistent performance as compared to the previous versions where I had issues. Good job . Any chance you could make a custom apk allowing adjustments? Most apps out there only allow basic stuff like voltage and cpu and governors. Would be nice to have touch boost options since I do notice this has a form of touch boost. I touch the screen and it will jump to 1100 quite often
[Sprint Samsung Galaxy S III] MikeWjF:
From what I've come to understand, lower voltages may cause the system to demand even more of a pull on the battery.
[Sprint Samsung Galaxy S III] meyerweb:
Watts = volts * amps

If the processor needs a certain amount of power (watts), and you undervolt too much, it's going to draw more current (amps) from the battery. If it needs to draw more current than the circuitry can provide, you'll get processor errors and instability. Based on the success many people have undervolting, it would seem that the default voltage values include a bit of a safety margin. But undervolt too much, and you exceed that margin, with the expected results. And there's a range of processor tolerances. Some accept more undervolting than others.

Overvolting, OTOH, will reduce the current draw to provide the processor with the same amount of power.

So there's a fine balancing act. Without comparative testing on your specific device, it's probably hard to predict the exact impact of any level of under or overvolting, especially when you're also under or overclocking.
[Sprint Samsung Galaxy S III] sitnamzug132:
Is the Stability Test app still working on JB4.3? The latest version of the app is from 12/25/2012, and it freezes and crashes around 4 minutes even at stock voltages . . . My setup is relatively basic - I'm running Wicked MK3 w/ dkp (the 12/26 build); zen/freelunch and min@270 max@1242. I've been undervolting -50 across the board for a few days now and haven't noticed any lockups/reboots, which leads me to believe it's an app issue. Thoughts or recommendations?
[Sprint Samsung Galaxy S III] enzoevo:
Dkp is already undervolted to begin with. If it fails you need to up the voltage.
[Sprint Samsung Galaxy S III] marcran75:
I was having issues with Stability Test app crashing too.
[Sprint Samsung Galaxy S III] techdog:
As was I so I just didn't use it. I assumed there was an issue with the app since I wasn't having any issues with the phone rebooting or acting oddly.
[Sprint Samsung Galaxy S III] enzoevo:
I've run it a dozen times or so and no crashes. I can't say for sure that the app is fine, but so far I've not had any issues.

I've run it on 3 versions of dkp, testing from 54 - 1.5GHz (750 - 1150ma). I can't run at 700ma as the phone just wonks out.
[Sprint Samsung Galaxy S III] techdog:
[MENTION=4932679]decimalman[/MENTION]. I feel like this is the best TW 4.3 kernel version you have come up with yet... I am running 54 Mhz min with 700 mv minimum voltage, freelunch governor, and zen i/o scheduler. It is running smooth as anything. It is responsive and I am getting great battery life.

Thank you so much for your hard work.
[Sprint Samsung Galaxy S III] kb9klc:
This is exactly what I've experienced on two phones since going to 4.3, slower charging overall. Thanks for the info.
[Sprint Samsung Galaxy S III] andee39:
Hi,

I just installed MOAR 7.1.0 with 12/26 build. I've noticed a bit of a hit with battery life so am trying to educate myself on kernel tweaks to imporve performance and most importantly, improve battery. I downloaded the tools from the OP and watched You Tube video which offered a nice introduction into tweaking the kernel but to be honest, still a bit over my head but will keep reading. :D

Before I make any changes I need to ask what is probably a really stupid question so I apologize in advance :o - would having an extended battery make any difference in doing these tweaks? I use gorilla gadget 4500 mah batteries and prior to MOAR 7.1.0 was getting great battery life.

Thanks in advance. Great work with the kernel! :good:
[Sprint Samsung Galaxy S III] MikeWjF:
No, tweaks or custom kernels should be affected by whether the battery is extended or not. The battery itself should perform the same way no matter what.
[Sprint Samsung Galaxy S III] andee39:
Thanks for the quick response!! :good::good:
[Sprint Samsung Galaxy S III] kb9klc:
I noticed with mine, the first charge took longer. While I'm new to all of this cpu tweaking, I can tell you the first day I did a few minor changes (mentioned in the first part of the video) the battery life was simply awesome. Like you I'm learning. Hang in there and see which changes work the best for you.
[Sprint Samsung Galaxy S III] MikeWjF:
I've never used an extended battery but I've heard that sometimes it can show 100% for a while before the light turns green. Even more so than the stock battery.
[Sprint Samsung Galaxy S III] andee39:
Thanks and appreciate the encouragement. :cool:

---------- Post added at 10:12 AM ---------- Previous post was at 10:11 AM ----------

Thanks. (apparently I've used up my thanks quota for the day!) :laugh:
[Sprint Samsung Galaxy S III] rompnit:
The XDA app or TapaTalk have no quota ;)
[Sprint Samsung Galaxy S III] andee39:
Good to know! I use the XDA app on my phone and just yesterday installed Tapatalk but haven't played around with it yet.

Seems kinda silly to limit thanks to people. ??

Thanks!! ;)
[Sprint Samsung Galaxy S III] sitnamzug132:
First of all, I gotta say thanks to decimalman because my phone is extremely responsive with the latest kernel, and dkp is probably the best I've used in that regard. Unfortunately, my battery life is leaving much to be desired. I've been playing around for the past week trying to figure out what the issue is. It gets to deep sleep, and BetterBatteryStats doesn't report any unexpected wakelock behavior, but I'm still losing insane amounts of battery -- overnight my phone went from 100% to 68% in 7 hours on wifi! I already posted my setup but here it is:

12/26 dkp - d2spr kernel

Scheduler - zen

Governor - freelunch

Min Freq - 54mHz

Max Freq - 1404mHz

Voltages - -50

Also running operation_killjoy_122213. I've turned off all syncing and disabled google now, motion controls, etc and battery life is still dismal. I'm pretty sure it's not physical battery itself because everything was fine coming from MD4. If anyone has any suggestions/recommendations please let me know!!
[Sprint Samsung Galaxy S III] meyerweb:
You may well need a higher voltage at that low a frequency. If the voltage is too low to to supply the required power (watts) to the processor, it will draw more current (watts = volts * amps). I'd try a couple of things, one at a time, to see if anything makes a difference.

1. See what apps you have running in the background over night. Facebook, for example, seems to do background syncing even when you tell it not to, so FB can spy on where you are and what you're doing.

2. Assuming you're using Trickster, look at the info page and see what clock speeds it's spending the most time at. If it's not the lowest speeds, something is running in the background and consuming cpu. I find the app System Panel to be very useful in ferreting out what: https://play.google.com/store/apps/details?id=nextapp.systempanel The pay version has a monitoring feature that can be very useful.

3. Bump your min frequency up a few steps, and see if that makes a difference.

4. If that doesn't help, or not much, try raising voltage back to stock, or maybe even a little more, at the slower cpu speeds. If that makes a difference, see if you can support the lower clock speeds at these higher voltages.
[Sprint Samsung Galaxy S III] techdog:
I would also uninstall KillJoy until you get the battery drain figured out or stabilized. To be honest, I felt as if KillJoy caused my battery to drain more, and also didn't help responsiveness. I went back and forth with KJ for days and finally decided that while KJ sounds like it can provide some real improvements, it just wasn't working with my setup. Without KJ I am having better responsiveness and my battery is significantly better.

I am running 54 MHz min frequency, 700 mA min voltage, 1188 MHz max, freelunch governor (with defaults), zen I/O scheduler.

Just my thoughts. YMMV.

[Sprint Samsung Galaxy S III] meyerweb:
Thanks. I meant to include that advice, too, but forgot. That's probably the first thing to do.
[Sprint Samsung Galaxy S III] andee39:
Just tried installing voltage control as mentioned in the video but I keep getting unfortunately voltage control has stopped message. I did send a report as asked in the app. Just wondering if you might have come across this? :confused:
[Sprint Samsung Galaxy S III] prboy1969:
That is almost exactly the same setup that I am running. WIth a few exceptions, which may be the big difference. I average about 1% drop per 4hrs. I'm running OKJ ( latest release ) . Keep in mind you should also check your sync intervals. Make sure that they are something that is a happy medium for battery life, and use. In addition to what you have listed, I'm running Greenify Pro. I have GPS ( Google Play Services ) Greenified. Which IMO made a huge difference in battery life. Lastly I'm running DS Battery Saver Pro. It's set to Balanced.
[Sprint Samsung Galaxy S III] techdog:
I had that same issue with the voltage control app. I just used Trickster Mod to set the voltages.
[Sprint Samsung Galaxy S III] andee39:
Will give that a shot. Thanks! :good:
[Sprint Samsung Galaxy S III] kb9klc:
I see reading further you got trickster installed. Yes that's what I'm using.
[Sprint Samsung Galaxy S III] andee39:
Can't take the credit. It came pre-installed on MOAR 7.1.0. :D

I got as far as changing scheduler and governor. Next in the video was setting min/max. Is that the choice on the general tab under cpu frequency control? :confused:
[Sprint Samsung Galaxy S III] kb9klc:
The frequency control is in the tab right above where you selected "free lunch". Yes CPU frequency control...
[Sprint Samsung Galaxy S III] andee39:
Great. At least I was in the right spot. Was just about to say something is terribly wrong b/c the numbers I show there are quite large but then it just occurred to me the triple zero at the end of both numbers was throwing me off. So the min of 384000 is actually 384 and max of 1512000 is actually 1512. Otherwise when he states in the video to set max to I think it was 1234 or something like that, it would be less than the min which makes no sense but if the min is 384 than that works. If you don't mind me asking, did you do all the items he mentioned in the video? (undervolting, etc?

I guess I'm highjacking the thread here with my issues. Would you mind if I pm'd you? :eek:
[Sprint Samsung Galaxy S III] kb9klc:
I took the liberty of PMing you sir.
[Sprint Samsung Galaxy S III] andee39:
Yes, that is correct. I leave mine plugged in for some time after the green light comes on and it shows 100%. :)
[Sprint Samsung Galaxy S III] shehroze3:
For some reason whenever I run this kernel on slimkat, any images on the screen will start to stretch and do weird things and then go back to normal for a few seconds and then start again. The only thing I change is the gov to free lunch and the scheduler to sio. This only happens to me on 4.4.2 not on tw 4.3
[Sprint Samsung Galaxy S III] MeAtKeRtN:
Running the dkp 12/26 TW4.3 with Wicked Sensations...

Super ridiculous battery life and performance all around... loving it.

Any recommends on an app to initiate/toggle fast charge (Fast Charge reads kernel as non root) or a script that can be run at boot to do the same would be the proverbial icing on said cake. Thanks in advance for ideas.
[Sprint Samsung Galaxy S III] ruthlessptizzle:
Trickster mod app has fast charging voltage control and other things for this kernel I it's what I'm running so just got to play store and download it

[Sprint Samsung Galaxy S III] techdog:
Hate to sound like a broken record.... But... Have you tried Trickster Mod???

:)

[Sprint Samsung Galaxy S III] meyerweb:
I believe the setup in MOAR already has it undervolted by -50, so be careful making it any lower.
[Sprint Samsung Galaxy S III] andee39:
Thank you for your input. So for I have only changed the i/o and governor. Trying to get the hang of this kernel tweaking but to be honest, I'm a bit lost. When you say undervolting by -50, is that the same as he states in the video to start at the max he suggests and then decrease each voltage below it by 50? :confused:
[Sprint Samsung Galaxy S III] meyerweb:
Yes, but his wording is confusing, at least to me. What he means is reduce each existing value by 50. So if, for example, the stock values are

1512MHz - 1200 mv

1458MHz - 1187 mv

1404MHz - 1187 mv

you would change them to

1512 - 1150

1458 - 1137 (NOT, as I first thought, 50 less than the prior value, or 1100mv)

1404 - 1137 (NOT, as I first thought, 50 less than the prior value, or 1050mv)

Does that make sense?
[Sprint Samsung Galaxy S III] shehroze3:
Anyone using this kernel on aosp?
[Sprint Samsung Galaxy S III] ruthlessptizzle:
Yes I'm currently using trickstermod

Squirting that Wicked Wiz
[Sprint Samsung Galaxy S III] andee39:
WOW I'm confused. Just doesn't make sense to me. I understood him to mean, for example I believe he changed his max to 1242 (mine is actually 1512)

1242 (currently 1100) would become 1050

1188 (currently 1100) would become 1000

1134 (currently 1075) would become 950

etc etc

I also don't understand why some of them have the same value like you state above, 1458 and 1404 would both be 1137? How would you know to keep them the same? :confused:

Appreciate you trying to help me. :)
[Sprint Samsung Galaxy S III] ruthlessptizzle:
I need the mhz normal I play high end games but I reduce by 75 some have went to 100

Squirting that Wicked Wiz
[Sprint Samsung Galaxy S III] meyerweb:
That's what I thought he meant, too, but as I started making the changes I realized that the voltages were dropping very quickly into territory that was impossibly low. Also, if you look at the changes he actually makes in the video, you'll see he's doing what I explained, not what it sounds like. Follow that approach a bit further, and you get:

1080 - 900mv

1026 - 900mv

972 - 850

918 - 800

864 - 750

810 - 700

756 - 650

702 - 600

648 - 550

This is probaby too low a voltage for the cpu to operate at already, and if you continue (I'm only listing every other step, to save space):

540 - 450

432 - 350

324 - 250

216 - 150

108 - 50

54 - zero volts.

This progression just isn't possible

I just reduced the stock voltages at each frequency by 50mv. So if 1458 and 1404 are both the same with the stock voltages, they end up the same after being reduced by -50.
[Sprint Samsung Galaxy S III] techdog:
Correct. For example, the lowest usable frequency for this kernel is 54 MHz and, I think, that [MENTION=4932679]decimalman[/MENTION] assigns a stock voltage of 850 mV to that frequency. I have lowered it to 700 mV which is reducing the voltage at that frequency by 150 mV, i.e., -150. I have reduced all of the other voltages by that same amount of 150 mV. So, 108 Mhz now has a voltage of 700 Mhz.

My Maximum frequency is 1188 MHz and the voltage assigned to that is 1000 mV.

This stuff can be tricky when you're just learning how to tweak the kernel.

The latest dkp kernel release for TW 4.3 is so smooth and responsive that you can lower you minimum frequencies and undervolt by a tremendous amount. I have never been able to make my minimum frequency as low as 54 MHz or my minimum voltage as low as 700 mV on other kernels and still have them be stable.

Remember, that the reasons for this is to reduce your battery consumption but you want your phone to remain as responsive as you expect or wish.

Good for you for asking. For each person that asks there are 10 others wondering the same thing that don't!

Good luck!

[Sprint Samsung Galaxy S III] andee39:
Ah, think this is starting to make sense now. Am on the road at.the moment. When I get home in a little bit will take another look and respond further. :D

Thanks.
[Sprint Samsung Galaxy S III] shehroze3:
Just to be clear, this is what I'm talking about.

All the icons got stretched but as soon as I touch the screen to do something, the go back to normal.

EDIT: Sorry I forgot to say that this happens as soon as I lower the min frequency at all. Even one step down does this.
[Sprint Samsung Galaxy S III] kb9klc:
So far I just lowered across the board -50. I haven't noticed any significant changes in anything yet. Although not a work day and I've not used it as much as I would then the battery life has been awesome. Using free lunch and row, max 1242 and min 54.
[Sprint Samsung Galaxy S III] jnow2:
Do you listen to music with these settings? My phone is also my mp3 player while working. Tried these settings and music suddenly...got...slower and skipped. Changed from free lunch to on demand and music plays normal but battery bogs down.
[Sprint Samsung Galaxy S III] techdog:
I do. It works fine for me. I use bluetooth to stream to speakers also. It works fine for me with both spotify and poweramp. What i/o scheduler are you using and what read ahead buffer size? I use 4096 and zen for the i/o scheduler.
[Sprint Samsung Galaxy S III] remotehugger:
I'm sure I'm gonna get reamed for asking this, lol, but has anyone tried the TW 4.3 kernel on a Virgin Mobile SIII ? We have a different CPU's than other SIII's and I didn't know of that made a difference - also not sure what build # other carriers use ? Mine is MK5 - any input would be great -

From my GSIII - jd's Stock/Rooted/Deodexed 4.3
[Sprint Samsung Galaxy S III] andee39:
Ah, you said the magic words that finally stuck - if both are the same with the stock voltages then you would keep those the same when reducing. Unlike you I did not pay 100% attention when he was making the changes. When he said to reduce each by 50 I did not watch him; just assumed he was reducing each number by 50. Poor choice on my part, especially since this is all new to me. :o

I am going to try the max at 1242 which would bring the lowest stock voltage down to 750. Does that sound about right? Will try row and free lunch.

I do have one other question. In the video the app he uses (unfortunately that app does not work on my phone) has a way to test the changes he made to see if there are any errors before setting at boot. Does trickster have an option to do that? Looked around a bit in the app but didn't see anything.

Thank you again for all your help with this. Very much appreciated! You actually helped me with an issue in a different forum awhile back. :D
[Sprint Samsung Galaxy S III] kb9klc:
That's the exact settings I'm using. So far so good. I'm still trying to figure out the best (better) I/O scheduler for me and my usage pattern usage. Good luck!
[Sprint Samsung Galaxy S III] andee39:
Appreciate your input. :)

Definitely tricky! So many settings. :eek:

I had noticed after flashing MOAR 7.1 that my battery had taken a hit and after seeing others post about the same issue and how they were tweaking the kernel I thought it would be a good idea to give it a shot to see if it helped. As you said, want to help the battery but make sure the phone remains as responsive as possible. :victory:

Thanks again!!
