@hardcore

Plz try to add lulzactive gorvernor into Speedmod for more battery save(IMO only).
[Galaxy S II Original Android Development] haieb:
sorry to dissapoint you but its because the battery gauge is inaccurate. for example the drain from 80% is happening much faster than from 100%. In addition to this, one chargecycle can´t calibrate the battery =) BUT u are right! the battery life is very good :p
[Galaxy S II Original Android Development] sadonlyone:
v16 it's almost fine, but there is no support for call recorder (skvalex). getting FC.
[Galaxy S II Original Android Development] anisbombaywala:
Can anybody confirm if call recording works with v17?
[Galaxy S II Original Android Development] jsompis:
Work fine for me with Phone.apk mod on XWKI8.
[Galaxy S II Original Android Development] Brotuck:
Yes it is normal when charging, but not when disconnected.

I reverted back to the latest K2-16 and the issues went away.

All is fine now !
[Galaxy S II Original Android Development] interfreak:
At the 16 hour mark, my battery still has 85% remaining. Will see how much is remaining in the morning. :)

[Galaxy S II Original Android Development] isotoper:
With k2-13 I had a huge battery drain when browsing the internet .

Has that been solved in 16/17 ?

Thanks!
[Galaxy S II Original Android Development] BrandoHD:
Only you can answer that question
[Galaxy S II Original Android Development] SupraN0va:
+ 1 to this. With this battery life , you will never see boot animation again. :-D
[Galaxy S II Original Android Development] guillots:
with a normal use?? 3g, wifi...blablabla.???

i have 55% of battery in 18hs18m....(with 14Hs of deep sleep, 3.41Hs of 200 and little minutes for the others...) with 2g...

i have the 17-test1......
[Galaxy S II Original Android Development] elbasso:
K-17 running wel here so far. Lots of deep sleep and little drain.
[Galaxy S II Original Android Development] roymustafa:
HI everyone. I had a problem with root explorer. While putting a file to system/app it says there is not enough free space to complete paste operation...

Help me please. I had never had this problem in the early versions of Hardcore kernels...
[Galaxy S II Original Android Development] tkalli:
I don' think this has anything to do with the kernel.

Have you checked system/app to see if there is free space?​
[Galaxy S II Original Android Development] KeesStolk:
Running 17 bèta since released without any problems.

my problem with wifi was gone after a reboot and never saw it again.

not much difference with 16.
[Galaxy S II Original Android Development] tkalli:
I had no problem with WiFi on 16 or 17.​
[Galaxy S II Original Android Development] SignalX:
please add support for MIUI and CM7 roms

cheers,

[Galaxy S II Original Android Development] interfreak:
I have 3G, WiFi, background data, auto sync (ie, everything) running.

Now at 1 day ,1h with 78% remaining. :)
[Galaxy S II Original Android Development] sydknee:
sorry if this is a dumb question and goes against hardcores principles, but any chance of tegrak's dual core support coming to this kernel??

this kernel rocks btw, for me by far the best/slickest, and beats siyah and the rest.....
[Galaxy S II Original Android Development] SaschaHa:
Had reboots while cleaning ram (K2-16) and when opening CWM in HDMI/MHL-mode (K2-17).

For me it is the best kernel because of the energy efficience, but an integreation of the sio scheduler from the Siyah kernel would be great :D
[Galaxy S II Original Android Development] renton82:
Is there a way to calibrate?
[Galaxy S II Original Android Development] KennyLegend:
Charge to 100% with phone off. Pull the battery for minimum of 90 s ti make sure the cpu powers down. Put back in battery and reboot. That's all is needed. The S2 does NOT need to be calibrated.

back button too not working!! worked when i used Cwm came with CF-Root!!
[Galaxy S II Original Android Development] rajaspidey:
this kernel is based on stock samsung kernel, MIUI & Cyanogen are direct from ANDROID Source so i don think it's possible!! :-)

What about k2 17 final ? I dont wanna flash test :)
[Galaxy S II Original Android Development] alexkno:
So, I am more and more happy with K2-17test1. Now running phone for 25hours with 41% left.

2:35h screen on, 5:49h wifi on, about 11hours 3G on, sync active all the time.

Even downloaded new maps for my navigation (about 600MB).

Screen on auto mode (but with lower values).

It's really good!
[Galaxy S II Original Android Development] coolfire:
Sounds awesome! btw, what ROM are you running? :)
[Galaxy S II Original Android Development] sadonlyone:
on speedmod v16 getting FC.

I'm talking about CallRecorder v1.39 from skvalex not about phone.apk mod. with stock kernel it's working fine. I'm on XWKI8 too.

I didn't test it on v17...
[Galaxy S II Original Android Development] Jonjungle:
26hrs here and still 62% left, Wifi always on. K2-17 is fantastic so far, nice work Hardcore! :D
[Galaxy S II Original Android Development] hardcore:
Thanks! What I'd like to know is, if you can compare it to K2-16. How much better is the battery life - is it significant?
[Galaxy S II Original Android Development] lrcquest:
How is the KJ3 franken??? If you were from KJ2, noticed any changes??
[Galaxy S II Original Android Development] pedestre:
I can't see any differences between k2-17 test1 and K2-16 talking about battery life. This is my experience with 3 cycles.
[Galaxy S II Original Android Development] interfreak:
Running awesomely on the KJ3 Frankenstein! seems much more 'solid' and a bit smoother than KJ1/2.

Now at 1 day, 14 hrs and 41mins with 42% battery remaining. Everything still left on and have used the phone a fair bit today. :D
[Galaxy S II Original Android Development] Brotuck:
K2-17 has reported issues with staying on 200mhz after disconnecting usb cable.

I reverted back to K2-16 and all is fine now.
[Galaxy S II Original Android Development] Deviser:
I don't notice a big difference in battery between k-16 and k-17...but this isn't very scientific.
[Galaxy S II Original Android Development] BAWS:
I´ve got 97% drain overnight with k2-17

I had 98% drain overnight with k2-5.

And I have the Samsung extended batterykit with a 2000mA battery

edit: yes of course I meant to write 3% drain on 17 and 2% drain on 5
[Galaxy S II Original Android Development] milan188:
Hello

Im using Siyah 2.1.1 and I made changes to the init.d scripts via voltage control. I changed the voltages in the cpu and gpu and increased the charging current.

I want to try Speedmod again (Tried K2-2 last). Will the kernal clash with these settings or overwrite them and use its own?

On Siyah when I set a screen off profile of 100-200 the phone can wake from deep sleep. On previous speedmod kernals(K2-2 and before) i set a 200-200 screen off and the phone didnt wake up. Should I use a screen off profile for speedmod?

Thanks
[Galaxy S II Original Android Development] kersey:
Have decided to give K2-16 a try from all the good feedback on here but coming from CF-Root have noticed after flashing that the screen brightness is a lot lower than CF-Root on the same manual setting :confused:
[Galaxy S II Original Android Development] isotoper:
Hi

Sorry, tried to search but no help...

Does any battery calibration needed after kernel flash ? (or it's just a new rom issue ?)

Another thing :

The persons who liked the k2-17 test battery - Is the battery drain when browsing the internet gone in this version ? Did you browse the internet with this kernel ?

Thanks.
[Galaxy S II Original Android Development] Cygnuss:
Its a lot better with K2-17 i tested vs K2-16 and managed to get a few more hours of bat
[Galaxy S II Original Android Development] coolfire:
No necessity to use a screen off profile with speedmod. Hardcore has optimised that in his kernel..

Sent from my SGSII
[Galaxy S II Original Android Development] cipetonk:
I read somewhere in this thread setcpu is not recomended for this kernel
[Galaxy S II Original Android Development] planetf1:
I can confirm I am seeing the issue with 2-17 whereby if the phone is charged off USB and then unplugged, the phone fails to go into deep sleep until next rebooted.

BBS isn't reporting any system wakelocks nor any significant user wakelocks.

This (as has been mentioned) seems to be a nasty 2-17 regression.

From another thread (thanks gokhanmoral and entropy512):
[Galaxy S II Original Android Development] Pacifiste95:
Better battery life with k2-17 :D
[Galaxy S II Original Android Development] blade3200:
To me k2-17 test1 is way better than k2-16 in deep sleep, watching movies and playing angry birds.

At least 5% to 10% more battery.
[Galaxy S II Original Android Development] ithehappy:
A confirmation on this would be great.
[Galaxy S II Original Android Development] Seifer1975:
I don't have this issue. And I have been charging and plugging off a few times today.
[Galaxy S II Original Android Development] pedrolopes665:
A little research would be better.
[Galaxy S II Original Android Development] akbarhash:
Not to troll or anything but I was shocked to see this message till I realized that you made a mistake. If you drained 98% then you would have only 2% battery left. Anyways what you meant to say is that you drained 3% on k17

[Galaxy S II Original Android Development] mbroeders:
Cannot confirm, setCPU works just fine here. Don't know if it is really necessary, but it's giving me zero problems...
[Galaxy S II Original Android Development] coolfire:
Obviously, it's just a language mixup, otherwise nobody would bother with SpeedMod. :p
[Galaxy S II Original Android Development] BrandoHD:
To all the guys inquiring about SetCPU, why not just do an "advanced search" using "hardcore" in the "username field" and "setcpu" in the "Keyword(s)" field???

After 396 pages, I would assume that SetCPU was already mentioned
[Galaxy S II Original Android Development] pedrolopes665:
I know the "because" of this question, but I will not say cuz it should be considered flame with these members.
[Galaxy S II Original Android Development] planetf1:
Were you charging off AC, or off an active USB connection (PC etc).

I'm thinking it doesn't apply in the former case -- I never have an issue after unplugging from a charger, but did after unplugging from PC.
[Galaxy S II Original Android Development] tkalli:
I don't have this problem when disconnecting from AC or the PC USB.​
[Galaxy S II Original Android Development] Seifer1975:
Charging off a PC. But I don't have this issue on both. I don't use kies and has frozen the mtp command though.
[Galaxy S II Original Android Development] lrcquest:
& as posted earlier from Kennylegend

Charge to 100% with phone off. Pull the battery for minimum of 90 s ti make sure the cpu powers down. Put back in battery and reboot. That's all is needed. The S2 does NOT need to be calibrated.
[Galaxy S II Original Android Development] It_ler:
Same for me running SpeedMod K2-17 test1.

So, it seems to be a "feature" of cwm 4.0.1.4 and 4.0.1.5 recovery.
[Galaxy S II Original Android Development] interfreak:
2 days and 35mins with K2-17, still 35% battery remaining. :D
[Galaxy S II Original Android Development] isotoper:
What (??)

You probably hardly used your phone.
[Galaxy S II Original Android Development] henriquesb:
Not very scientific, but I'm back to K2-16 as K2-17test1 seems to drain a lot more in Wifi while using. IMMV of course.
[Galaxy S II Original Android Development] planetf1:
I had some strange wifi behaviour. Thought it was cause of heavy battery drain (25% of time awake even when untouched). Switched to 3G, went away.

But by the next day all back to normal again. There are so many variables being sure is tough...
[Galaxy S II Original Android Development] joezy07:
hello, a fan of speedmod here.

I wanna ask, is v17-test is better than v16 ?

or do I wait for the v17 final ?

I'm still in v13 now. :D
[Galaxy S II Original Android Development] CamoGeko:
I would say go for it and try v17, worked better than v16 for me. Few other people have reported the same.

[Galaxy S II Original Android Development] xmfpdlemalnz@hotmail.com:
Please report your experience after a couple of cycles.

Otherwise it's just gibberish
[Galaxy S II Original Android Development] KennyLegend:
Not really. One cycle should be enough. The battery in the S2 does NOT need calibration.
[Galaxy S II Original Android Development] frw99:
With v17 I had only 9% drain in 12hours. BMW shows 9mA during this period. Never had such a low current value with any other kernel. GREAT!!

For me SpeedMod is the best :-)

I think it's time for a donation...
[Galaxy S II Original Android Development] coolfire:
hardcore's great work is worth donating for! :D
[Galaxy S II Original Android Development] interfreak:
From the hints he dropped earlier, he may get a flood of donations next week...
[Galaxy S II Original Android Development] It_ler:
I think you are right.

There are many different variables which have influence on battery life.

I flashed SpeedMod K2-17 test1 kernel yesterday and charged to 100% (phone off).

Then I pulled the battery out for about 5 Min. and put it back in then.

From evening to night (ca. 2-3 hours) battery was down to 84%.

Turned off phone over night.

Today morning, battery was at 83%.

I think that 1% of battery drain is good - at least fine for me.

As I was running only stock kernels and CF-Root kernels before (last one was CF-Root for XWKJ3), I can only compare with those.

My first impression is that with "heavy" usage (wifi + Skype + Talk + News-Reader + Internet + Screen on + Email synch + ...) the battery life is only as good as with the stock (CF-Root) kernel.

But with "low" usage (more deep sleep time) the battery life seems to be better than using stock (CF-Root) kernel.

P.S.:

As it is not so important for me, I add this information here in post scriptum section.

With SpeedMod kernel it was the first time I reached more then 4.000 points in Quadrant Standard benchmark. (Stock and CF-Root kernels were always between 3.400 and 3.700 points and SpeedMod K2-17 test1 has about 4.100.)

Other benchmarks showed different results - most of them with no big difference between SpeedMod K2-17 test1 and stock/Cf-Root kernels.

Only in CF-Bench (ok, it is from Chainfire) the CF-Root kernel (XW_KJ3) had a little better Java score (and as consequence better overall score too) than every other kernel I used before.

But as I said, benchmark scores are not as important for me as battery life.

Had more than one random reboot with 17, thought it was down to dolphin browser.

Didn't touch the browser this morning and the phone turned itself off completely (which it's done a couple of times before) . . . gone back to 16 to see if the same happens

edit: also might be worth noting that i travel up and down in lifts quite a bit, consequently i lose connection, then reconnect etc. could this be a cause?

[Galaxy S II Original Android Development] Jonjungle:
Yep, always like that since 2.3.5, I am a moderate user but still Speedmod Kernel made a big difference
[Galaxy S II Original Android Development] s2d4:
lol, display lower than AOS.... Screen on time like 1hr or something?

use your phone man.. you bought a super pretty phone...
[Galaxy S II Original Android Development] doongoo:
to right understand you:

we can use set CPU to change the MHz values but we should let the stock (ondemand) governor?

Or we shouldn't use setcpu at all?
[Galaxy S II Original Android Development] hardcore:
I recommend not to use setcpu to change settings at all.
[Galaxy S II Original Android Development] Life Engineer:
Thanks man for this great kernel!

I installed setcpu just out of curiosity and i found that the default governor is "conservative"!!! Is it right?! Or something is wrong here?!

EDIT: BTW i see a lot of people talking about deep sleep! How can i know if the phone is in deep sleep or not?!

1 post before confused me a lot, it says something like :"80% of the time was deep sleep while 10% was at 200mhz and the others ..."!!! But 200mhz is the minimum freq on this kernel right?!?!

wrong thread zOMG sorry
[Galaxy S II Original Android Development] ruubs:
Hello folks,

I'm new to android and i am trying to learn alot here.

So i will receive my sgs2 today or tomorrow and i want to root/tweak/flash it etc.

I'd read that the speedmod kernel from hardcore in combination with litening rom is one of the best options.

Now i know how to flash the rom, but i dont know how to flash/install this kernel.

Do i have to flash the rom first and after that the kernel, or?

Sorry for the noobish questions, hope some1 can help me.
[Galaxy S II Original Android Development] TvBTvB:
You will have to flash Speedmod kernel after flashing the Litening rom since Litening has Ninphetamine-2.0.2 kernel integrated. You flash a kernel as PDA in Odin, just like the Litening rom itself :)
[Galaxy S II Original Android Development] elbasso:
Flash CF kernel through ODIN to get CWM and root. Then flash Lite'nin ROM through ODIN and let phone reboot, go into recovery and flash speedmod Kernel.
[Galaxy S II Original Android Development] alucine:
@hardcore another problem in T12, lag with turn on screen.

With CF-Root-SGS2_XX_OXA_KG1-v4.1-CWM4.tar kernel, push on and screen on very fast about 0,2 seg

With SpeedMod kernel, push on and exits delay 1 seg to screen on.

You can make the test.

1º turn off screen.

2º don't touch telephone about 5 minutes

3º turn on screen
