I like the auto backup of efs, (even though I already made my own), but have you thought of gzipping the partition image since it is mostly empty it compresses good and then would only take up ~22KB instead of 20MB. At least that is the compression I got when I backed up my efs partition when I bought my phone.
[Galaxy S II Original Android Development] gokhanmoral:
I don't think we would have any problem with disk space but I will do it in rc2 because efs is backed up only once. if there is already efs backup in /data/.siyah it won't backup again.

I'm adding the compression now. thanks for the suggestion.

Sorry if this has been answered elsewhere but I couldn't find it exactly:

I installed this latest Kernel RC1 to Batista's ROM. I had been running SetCPU with the Abyss kernel.

I wasn't sure how to make an UV script form scratch so I took one on my SD card that I had saved previously - 96undervolt and modified it by copy / paste of the latest script referred to a few posts back.

I then put this file in the system/etc/init.d folder

Rebooted

I couldn't see any changes in SetCPU and CPUSpy, etc.

I now have SetCPU disabled on boot

What is the best way to tell if the script is working or not?

Do you suggest not running SetCPU at all (I saw a "roleyes" comment about using SetCPU elsewhere here)?

If the above is correct is this 96undervolt script the only thing we (the average user) need to help with UV'ing and battery saving best?

Thanks for patience!
[Galaxy S II Original Android Development] gokhanmoral:
the undervolting script echoes something to a device file.

the best way to tell if it is working is to open the same file with a file manager as a text file.

if the script is working you will see the same values that you have echoed.

[Galaxy S II Original Android Development] AndreiLux:
I flashed KI3 and indeed it's using the 800MHz step too. It happens because of suspend rampaging in the background. If I set the phone into airplane mode, then it will stay in deep sleep even with StabilityTest running correctly. You said that the hardware needed to go to 800MHz for it to suspend correctly, so that might be something you can't fix. Well I'll test it if you say you'll try to set it lower.

I've got a feeling this won't be fixable until Samsung actually changes the drivers.

Edit: So actually this still doesn't say if profiles work or not. It just tells us that the AOS bug is more ****ed up than one thought. I need some app where I can actually manually set a wakelock to artificially test that. MIUI has an option to prevent the phone from entering sleep. I'll see if I find something similar.
[Galaxy S II Original Android Development] hausmanis:
Im gonna test your script but first a question, its easy to see where you set your UV voltages, but i cant find anywhere to underclock the CPU, max it to for example 800mhz am i blind or ?

Have you tried 2.6.7 ?

---------- Post added at 12:29 PM ---------- Previous post was at 12:19 PM ----------

Hi all,

Yesterday i was playing at Reckless Racing and my phone was pretty hot, i checked and it was Full speed 1200Mhz... forcing the speed to 800Mhz the game was smooth as at 1200Mhz, forcing at 500Mhz the game is sometimes a little slower (many cars) but very playable.. so i end up putting some rules in tasker to reduce my max speed to 500 or 800 depending on the game/application that is running.

I've asked sometime ago if someone know the difference (performance side) between single core at 800Mhz and dual core at 500Mhz, nobody seems to have a response... ;) so i've done some bechmarks and a thread : [BENCH] Single/Multi Core - 500/800/1200 Mhz

gokhanmoral : I remember seing in one of your post that the battery cunsumption was not correctly reported ... is there a way of having a real value for the cunsumption ? (i would like to compare the cunsumption of each mode).
[Galaxy S II Original Android Development] pikachu01:
Your up_threshold for your governor might be too low (it increases the frequency too easily when load is not that high).

What governor are you using?
[Galaxy S II Original Android Development] d3l1:
me too, gsm/wcdma seems to consume less but wifi seems to have massively increased it's battery drain in idle. better battery stats shows nothing connected to wifi but when wifi is off the battery drain is better then before. I lost 3-5% / hour with wifi on and the phone in idle last evening.

settings: 200-1200, sio, ondemand, gpu low state lowered to 133Mhz and voltage to 850mA, everything else is stock values.
[Galaxy S II Original Android Development] veyka:
We don't seem to have the hardware to do it, so at the moment, there is no way to see drain, and any app that says it can is a poor estimate at best.

[Galaxy S II Original Android Development] droid_1989:
Why do some apps say not compatible with my device, i.e, ROM TOOLBOX had an update, but when I go to Market it says it's not compatible. Didn't get this using SpeedMod, converted over to Siyah to try it out.

Is it something to do with the build.prop file?
[Galaxy S II Original Android Development] Lulavc:
Install Market Enabler.
[Galaxy S II Original Android Development] tarpek:
Hmmm... I can't see cpu usage and can only modify cpu, gpu is not visible?

;(

Why
[Galaxy S II Original Android Development] Entropy512:
That's because there is no definitive answer - some tasks are easily parallelizable and multithreaded, some tasks are fundamentally single-threaded. A well-parallelizable workload will do better with dual-core at 500 than single-core at 800, and probably almost match single-core at 1000 while consuming less power (due to operating at a lower voltage).

Other tasks don't spread well across cores, so single-core at 800 will beat dual at 500 for those.

Power consumption estimates in Settings->About->Battery Usage for 1400 and 1600 will be wrong unless you add entries for them to power_profile.xml in framework-res.apk. I don't know what the "right" numbers for these are, but you can guess from the general rule of thumb that power consumption is proportional to the frequency and the square of the voltage. (At full load at 1400/1600, leakage currents won't be a contributor and you don't have to worry about idle states in power_profile.xml, since it handles that separately.)

Dual-core power consumption estimates may or may not be broken - no one really knows the answer to this one.

If you want to see the REAL system consumption for a given operational state - you need to wire up a current sensor between the battery and the phone. I'll try to dig up an example thread on this from the GNex forums later.
[Galaxy S II Original Android Development] Honusnap:
Original ondemand from 2.6.7, i've also tried lulzative with extreme values : 98% to go up, 1 step up / 3 steps Down, and something like 40000us for up/down => same result.

At 500Mhz (dual) the game is sometimes laggy, but at 800Mhz (dual) it is really smooth.

And from the test i've done, increasing CPU frequency have no impact on 3D performance. (AI in the game need CPU of course, but no impact on 3D)

---------- Post added at 04:33 PM ---------- Previous post was at 04:32 PM ----------

It can, did you changed your DPI ?

---------- Post added at 04:53 PM ---------- Previous post was at 04:33 PM ----------

I'm not overclocked, i've just run some test with Battery Monitor pro (do not found a better tool) and it seems ... that at 500Mhz (single core OR dual core) it took 220mA and 330mA at 800Mhhz regardless of the dual/single core mode... !

=> The second core is disabled "logically" but not really... current is always supplied OR The battery cunsumption is incorrect.

Ps : Brightness fixed, airplane mode, wifi off

I know for an external current sensor, got one but not precise enought for this kind of test.
[Galaxy S II Original Android Development] pikachu01:
Weird. Your game must've put a load on the CPU so much that it's more than the threshold. Your game is still smooth as GPU is handling it well. A badly coded game perhaps?
[Galaxy S II Original Android Development] Honusnap:
Don't know how it is coded... but it one of the most beautiful game on android.. :)

I think that the game is already gaving something like 60frames/s at 800Mhz and go for 60+++ frames/s on 1200Mhz, but these frames are not needed... well at least not for me.. :D

Phone heats up only when the CPU is constantly hitting high frequency. I think its some misbehaving app utilizing the CPU for no reason. Install watch dog and monitor, you will find the culprit within half an hour max.. :)

Siyah kernel has reached the refinement not to have such CPU behavior due to kernel issues. I'm confident its not the kernel
[Galaxy S II Original Android Development] Crescendo Xenomorph:
That's why, I don't think it's the kernel issue.

And the battery also last only a few hour (about 7 hours of light usage)....

I've had a pretty horrible batterydrain, supposedly cause by android_system. (Usually accounting for in between 30% and 40% of all battery drain)

Especially these processes seem to be the reason for that:

contactsstorage (is that the english name?) I'm talking about the thing that saves all your contacts. Kontaktspeicher in german.

.com.samsung.InputEventApp

BluetoothAvrcp 2.3.6

Any ideas on that?
[Galaxy S II Original Android Development] :
I've got the same prob here. German 2.3.6. LA4, starts with massive draining from around 40%.

BUT, I'm currently on N.E.A.K. Kernel, not on Siyah (please forgive me, guys ;-) ). So it has definetely nothing to do with the kernel, seems to be a general ROM problem.

Your looking at about 4h of screen on time, which is kinda standard with the stock battery, are you listening to music, if not you need to deal with your wakelocks.

Anyway, these comparisons are mostly pointless as consumption can be very different from person to person (wifi strength, channel, how congested the airspace it, mobile network signal strength, what bands its on, etcetc).

You do understand that the battery usage is a ratio between a few values right?

The more you use the display, the higher the percentage of it (and the lower the percentage of others)?

If you don't use the display, other less significant battery users will rise up?

[Galaxy S II Original Android Development] pikachu01:
Wait till its around 10-20% and then dump a betterbatterystats log. Just use your phone as you normally do. If one of the apps are going haywire and draining your battery, you'll know from the Battery Usage screen. Reading it while its 100% when there's nothing much draining your phone except small stuff (that will have a high ratio at the beginning).
