Just some tests I did a long time ago though, some people argued saying they were having major battery life with 100MHz, but sincerely, it ended as placebo for me...

If someone wants to check back with latest Siyah release just do like this ;) Full charge to 100%, Plane mode and whatever you want, even just force screen On and keep 2 cores online at 100MHz by setting Max. and Min. to 100MHz and put ondemand governor... whatever swits you, and test!

This is how this stuff is tested, not just with daily usage, as the save on battery on S3 are all quite small (as it's superb on stock) so better test properly :D :D

Btw 3.7 running great, and my multipdp stupid wake-locks seemed to be due to Facebood/FBMessenger, as I frozed them and TADÁ! From 7% to 2% multipdp wakelocks doing same test as usual (phone idle without sync on same table for 4 hours lol, I'm a silly tester :D)
[Galaxy S III Android Development] king.stivan:
i think its the bad signal coverage ..... anyways i just installed JB and so far the device is super snappy !! cant say about the battery live but i think i was at high/mid 90% 3.30hs ago screen time is 3hs and been installing all my apps and **** all the time :S so im now @ 50% battery if that helps :> im runing with SuperNexus build 1 with Latest CM Kernel :>
[Galaxy S III Android Development] radeonxt:
yes was planning to do that.

setting min and max at 100, then later min and max at 200 to compare.
[Galaxy S III Android Development] MuertoKo:
Hope you can share your results here to see if they match mines, so that we can conclude 100MHz it's useless (at least not noticeable) or if I may re-test :)

Btw harunjo, any special preference to set "sio" as scheduler instead of deadline or any other? Focusing completly on battery life? Is it tweaked sio?

Just couldn't find a word about it, even searching for "sio" is a pain as are only 3 letters :P
[Galaxy S III Android Development] radeonxt:
the top best 3 are sio,noop and deadline. found that on a thread here in xda.

noticed in galaxsih version something, there is an andreilux tweak for sio so i'm using sio for now hehe.
[Galaxy S III Android Development] MuertoKo:
So I missed that tweak :P That must be the case then :) So good so far, then won't complain :D :D

First time with sio here anyway, and hadn't even noticed, that means it might be good for battery but not nerfing at all my smoothness :D

Anyway, JB isn't as smoother as I've read here (tried one CM10 build today), definitely not the major improvement I've been reading this days in here... Surely due to un-finished HW Composition though :) Hope final release comes soon :D
[Galaxy S III Android Development] harunjo:
SIO> NOOP> Deadline > VR > BFQ > CFQ

http://xdaforums.com/showpost.php?p=25387200&postcount=1

Q. "Best I/O Scheduler?"

A.There is nothing called "best" i/o scheduler. Depending on your usage environment and tasks/apps been run, use different schedulers. That's the best i can suggest.

However, considering the overall performance, battery, reliability and low latency, it is believed that

SIO > Noop > Deadline > VR > BFQ > CFQ, given all schedulers are tweaked and the storage used is a flash device
[Galaxy S III Android Development] samaxen:

[Galaxy S III Android Development] MuertoKo:
Did some tests on Wi-Fi today :)

No wake locks this time on my 1st router and yes on my second router (PLC on the first one lol).

Definitely it's a noise matter, as I checked both networks with Wi-Fi analyzer app and the one causing wakelocks has 3 more networks on same channel and is more noisy ;)

Not kernel related then :)

Btw multipdp wakelocks I was having were sure to Facebook (not facebook messenger) so will switch to some other app for it! (8% wake and 20% more drain with than without O.o stunning!)

And please don't UP the thread, a good kernel wins it's place by itself :)

[Galaxy S III Android Development] MuertoKo:
Looks cool so far, gonna flash it and try both routers just to see if the wakelocks stay there on the bad router :P

Anyway, why did you revert pegasusq? I didn't notice any improvement but neither any drawback... Just to know :D

(min/max clock frequency on cpu hotplug... should we notice any visual thing? Maybe on System Tuner Pro or so? or just performance?)

Asking just to test properly :)

i am looking for XXBLG9 stock kernel..or just stock kernel boot.img..could you help me to provide the url link to it?
[Galaxy S III Android Development] samaxen:
I am using my Wanamlite v2 Customised by me. I removed lot of bloatwares as mentioned here but not all i still use good maps and other google stuff. https://docs.google.com/spreadsheet/ccc?key=0AqTvctlW89DtdC1qVUlLeVFTV3ZOdUtDclpBdVRQOUE&pli=1#gid=0

and added few tweaks floating around in the net.

But no undervolt as this kernel is already undervolted. My speed is also fast I got 6000+ on quadrant.
[Galaxy S III Android Development] radeonxt:
don't bother.

it has the same changelist with LG8.

:victory:
[Galaxy S III Android Development] harunjo:
thanks for review...i got little laggy when play virtua tenis...just wanna to see if my pegasus tweak impact to 3D performance

explanation for hot plug min/max freq is:

i notice..the cpu deep sleep is better with that hotplug tweak..i am still observing the cpu behavior here
[Galaxy S III Android Development] geistteufel:
I extract it and give you the link
[Galaxy S III Android Development] samaxen:
After 2nd Cycle of charge i got this. Normally my battery gets down to 70% after this kind of usage with other kernel

that is still new pegasusq but revert back my tweak to default value
[Galaxy S III Android Development] harunjo:
nothing new with xxBLG9
[Galaxy S III Android Development] geistteufel:
ok so I can install it and use your kernel, right?
[Galaxy S III Android Development] radeonxt:
yup.

as per changelist, it's the same.

:victory:
[Galaxy S III Android Development] harunjo:
yes its safe
[Galaxy S III Android Development] MuertoKo:
Reporting about Beta ;)

Wifi working great and at least no noticeable wake or problem, so as good as before at least :)

Pegasusq you were right, hadnt noticed lag on Dead Trigger but it was there O.o now I saw it as it has disappeared :) (Had some slight lag when map starting, but thought it was normal! Now it's gone with latest Beta ;) )

Hotplug... sincerely, noticed nothing, so at least as good as before ;) maybe better sleeping? Maybe placebo though :)

Today 18h device and 4h screen! (Hadn't played much today but still hard use on network today)

Just THANKS for this :)
[Galaxy S III Android Development] radeonxt:
tried beta8, there are times screen would turn on suddenly and won't turn off.
[Galaxy S III Android Development] harunjo:
hmm never had that problem with 38 beta
[Galaxy S III Android Development] MuertoKo:
Neither did I so maybe not kernel related ;)

Just running smooth on LG1 :)
[Galaxy S III Android Development] radeonxt:
never had that problem in previous version.

this was the only thing i flashed.

i'm on stock rom.

didn't install any apps.

nor do i have any user apps that run on background.

[Galaxy S III Android Development] harunjo:
did you flash back to v3.7?

is your problem solved with v3.7?
[Galaxy S III Android Development] radeonxt:
yes i don't have that problem in 3.7

reverting to 3.7 for now
[Galaxy S III Android Development] Khy50:
Don't know if it's just me but battery life on 3.8 b1 is not as good as 3.7
[Galaxy S III Android Development] harunjo:
thanks for sharing dude..i will check it
[Galaxy S III Android Development] harunjo:
hmm maybe other can share,? i cannot report the battery performance since i replaced my stock battery to anker battery
[Galaxy S III Android Development] jay_snake:
I tend to agree with Khy50, seems a bit worse than 3.7
[Galaxy S III Android Development] MuertoKo:
Amazon Anker? Link pls :P any report on how is it? Real improbement on that battery? Share results :) (asking here as I hadn't seen official thread on anker for SGIII)

Not for me but not testing properly as I'm on holidays so out of daily routine :) So you lead the test guys
[Galaxy S III Android Development] harunjo:
i got it free for review..you can find the review @ accessories section

maybe my pegasus tweak better to stay for v38..and also i can not see benefit for hotplug tweak

Battery and governours/schedulers

Hi all,

I just ordered a Polarcell battery (Amazon Germany) which is supposed to have 2400 mAh, which could really make a difference. I had Polarcell batteries already for my SGS1 and they were superb. Will report the next few days after I got it.

But mainly have a question to Harunjo:

Is there a reason why you removed all governours and schedulers apart from pegasusq and sio? Unfortunately by that my beloved deadline scheduler is gone.

Just want to understand if this was intention or a mistake.

Many thanks

Andi
[Galaxy S III Android Development] jay_snake:
Is that battery the same size as the original one? No additional backcover that comes with it?
[Galaxy S III Android Development] andip71:
Yes, absolutely. No additional backcover as this would be looking really ugly.

In case you want to have a look yourself:

http://www.amazon.de/PolarCell-GT-I...008COL2HQ/ref=pd_sim_ce_2/278-3740310-7667343

Sorry for OT, now back to the kernel.

Andi
[Galaxy S III Android Development] harunjo:
andi..your questions have been hot topics couple days ago here..you can read that.

and about why i removed all governor and leave only pegasusq, because this kernel only support pegasus..the reason i removed all unused governoor because i need reasonable kernel size..it must be not to big when you flash it

v3.8beta2

v3.8-beta2 online

-revert-->add min/max clock frequency on cpu hotplug

-midas-tsp: make touchscreen actions less chatty

-ashmem: Fix deadlock when System is low on memory

-re-tweak pegasusq (experimental)
[Galaxy S III Android Development] MuertoKo:
Remove? Remove pegasusq tweak I guess, right?

Will test it as usual :) what are we suposed to see now? :)

Btw found about Anker and does not seem worth for now... let's wait for a 2500mah thin one :D
[Galaxy S III Android Development] harunjo:
the "removed "word was typo..sorry
[Galaxy S III Android Development] MuertoKo:

v38-beta2

got good battery life here..with light usage
[Galaxy S III Android Development] losta:
what is the normal battery drain for you with the same time usage of 6hr with wifi off and gsm data enabled with light usage? since i rarely used wifi instead relied to my gsm data more frequently. just for a comparison sake :) many thanks in advance
[Galaxy S III Android Development] samaxen:
Bro, with v3.8 Beta2, I notice improvement in wifi speed, without much wlan_rx wavelock, please keep these patches
[Galaxy S III Android Development] harunjo:
with wifi battery life is better compare with gsm for me. usually with light usage like that i got 85-90% after 6 hours

Ok i have installed new version.. Just a quick question can i constantly flash youre kernel without to wipe something?.. I remeber when i had a htc sensation there was a kernel cleaner that i used before to remove everything from kernel

Verstuurd van mijn GT-I9300 met Tapatalk
[Galaxy S III Android Development] harunjo:
if you notice uncommon behaviour, than you can do wipe dalvik and wipe cache only
[Galaxy S III Android Development] korrel2008:
Then i will do that, just to be safe :)

Verstuurd van mijn GT-I9300 met Tapatalk
[Galaxy S III Android Development] samaxen:
If you read through the thread very well known developers like Hacre said no need to wipe anything for flashing Kernel.

Wiping is only needed if you r flashing some framework changes in ROM.
[Galaxy S III Android Development] korrel2008:
True, but one says this other says that, and from what i have learned from my sensation time was that when i flashed a new kernel always flash kernel cleaner first because there can be things left behind from old kernel that can make the new kernel not working well... Sooooo thats why asked :)

Verstuurd van mijn GT-I9300 met Tapatalk
[Galaxy S III Android Development] harunjo:
Dear jothi2lingam,

i dont have any idea since no log from you, conflict with checkrom maybe?

did you try to wipe cache and dalvik before flash the kernel , or fix permission after flash it? i am usually not doing wipe, and always flashing sucessfully

i am using omega rom 8.0 here
[Galaxy S III Android Development] qwerty12:
Hi,

Sorry to keep requesting, but I was wondering if you could add the following in your next update:

https://github.com/gokhanmoral/siyahkernel-sgs3/commit/ba52d49aef1b0a5e38745894fe4786db9feb125f and https://github.com/gokhanmoral/siyahkernel-sgs3/commit/1c6da6e163fa6f3a169fbe356b74c651e040c17c as these allow you to see past wakelocks in BetterBatteryStats so that you can better determine battery-wasting processes

I don't know if it's needed, but (and it's simple anyway): https://github.com/gokhanmoral/siya...a55a31184526f08b8702812e72be0#kernel/module.c

Are there any risks with this one? I'm not trying to fight or anything, but I've been avoiding kernels that do this because I have an aversion to raising voltages :)
[Galaxy S III Android Development] jothi2lingam:
I already tried wipe cache & dalvik and also fix permission...But results is still same..Can you guide me how check log from phone...Atleast i can help you to solve problem on this
[Galaxy S III Android Development] baste07:
i'm debating within myself which is better phenom or this kernel
[Galaxy S III Android Development] samaxen:
Maybe your download is corrupt try to download again and try again to flash
[Galaxy S III Android Development] kotty:
using checkrom with this kernel ..working great ..so far no problem ..
[Galaxy S III Android Development] harunjo:
you can use logcat, but since your problem in the bootloop..so there is no solution for that i think, maybe conflict with init.d or checkrom tweak...i must try checkrom first to make sure the root cause...maybe just a corrupted download? find below quote:

just flash those kernel and enjoy it

@qwerty12, you and me at same boat for "wakelock info" fix, and for bypass exfat module_layout, could you explain why this kernel need that kind of patch? i am not using exfat here
[Galaxy S III Android Development] qwerty12:
I don't think it does, it's just me being odd because I've seen it in other kernels (and, for some odd reason, think every kernel should have it - but it - as you say - might not be needed)

If I can format my 32GB microSD card with the exFAT filesystem, I'll see if the exfat modules work fine with your 2.4 kernel
[Galaxy S III Android Development] harunjo:
i will consider it..since that only small patch, i will put that in my todo list..
[Galaxy S III Android Development] jothi2lingam:
Harunjo...Now successfully have flash your kernel, its download error i think..Thanks guys

[Galaxy S III Android Development] eliashadow:
The last version (the only i have tried) is really impressive.

I thought that the cf root kernel was the best for me but i can say that this one is a little better.

Same very good performance but less battery draining especially in idle mode.

Thanks and keep up mister.
[Galaxy S III Android Development] harunjo:
this kernel actualy do cleaning , but only clean the content of initd folder

here my cleanup script credit to simone:

/sbin/busybox mount -o remount,ro /system
[Galaxy S III Android Development] harunjo:
yes i tends to agree with you..there is no scientific explanation for this wipe procedur..

see above clean up script for example why sometime we need to do clean up

my suggestion is..if you come from same kernel variant..you safely flash it without wipe.

sometimes there are alot built in tweak from custom kernel who can be impact to your rom performance..and also same condition with custom rom who can impact your current kernel performance..
[Galaxy S III Android Development] samaxen:
But I guess nothing is left from Harunjo's Kernel :)
