I kinda agree with you, but also kinda disagree.

I think what devilkin was trying to say about percentages is that too many people just look at the ratios, and ignore everything else. Sure, Android OS may be responsible for 90% of your battery use. But if your phone is sitting idle in your pocket almost all the time, there isn't much else to use battery, so Android OS will by high in comparison.

With regards to your "apple does not exist" statement, you are incorrect. In this case, the "apple" is the level of charge in the battery. You can measure the charge by looking at the voltage. When the battery is fully-charged, it outputs a certain voltage. As the battery drains, the voltage slowly drops. When the battery is almost discharged, the voltage starts dropping very quickly. If you know the "full" and "almost empty" voltages, you can get a fairly accurate indication of what percentage of charge is left in the battery.

That being said, you're right about needing to look at the actual usage numbers, not just the percentages. CPU time spent is an acceptable indication, but true power use values (like with MIUI) are better. 15 minutes of CPU uses more power @ 1200MHz than it does @ 200MHz, and both use more power than when the phone is in a deep sleep.

Given that the Samsung standard battery graph only shows times, that's the best way to look at usage. If Android OS is only using a couple of minutes of CPU time for every hour the phone's on, that's probably fine. If it's using 10 minutes for every hour, something is wrong. The phone's not staying idle as often as it should do, and you're using more battery because of it.
[Galaxy S II Original Android Development] astoncheah:
from my understanding, and i think it should be calculated in this way:

example from your picture:

battery left = 9%(total used 91%)

-os used = 94%

-cell stanby used = 3%

-phone idle used = 3%

then the battery used at os = (94%x91%)=85.5%,

at cell stanby = (3%x91%)=2.7%

at phone idle = (3%x91%)=2.7%

total used = (85.5%+2.7%+2.7%)=91%

i have no knowledge at this field. but i just think it should be calculated in this way. correct me if im wrong.
[Galaxy S II Original Android Development] fru.olie:
Well, I tried the kernel T-40 and observed big battery drain. In 4,5 hours my phone went from 100% to 55% by moderat use.

Now I went back to T-39, without changing anything, and my batterytime is better. After 4 hours from 100% to 91%.

I can't get the same batterylife, as others told, but I am quiet satisfied with the T-39 kernel...nice job. :)
[Galaxy S II Original Android Development] devbot:
There is something I dont get. I have a good battery life, more or less 3 days with 40 minutes screen on per day on 2g only (we have a bad 3g connection here so I activate it only when I need it) and I switch off data and sync during the night. The problem is that my phone is very often awake when the screen is off.

Looking at the partial wakelocks, everything seems fine... So is this kernel related?

I'm on VillainROM 2.5 with t40 but I had this also with VillainROM 2.4.2 and t39
[Galaxy S II Original Android Development] rodak:
Download Bettery Batter Stats and see what causing your wakelocks.

Edit: lol, sorry, missed your last line and second screenshot :)
[Galaxy S II Original Android Development] gtda:
Any one using this with xwki4, just updated and I love it. Just missing speedmod kernel
[Galaxy S II Original Android Development] Krooked22:
I've been getting excellent battery life using you're kernel. Youre work its very much appreciated. Thank you
[Galaxy S II Original Android Development] Auridran:
Yes. I'm using VillainROM 2.5 which is based on KI4.
[Galaxy S II Original Android Development] blackspp:
Just an FYI, cause I'm a happy chappy.

I'm now running the latest and greatest stock I9100XWKI4 with t40 and the speed, the speed is amazing! Not sure about battery live, fc's and what have you but on every second run I get this and how cool is that! I just love the view of 4000+ :)

[Galaxy S II Original Android Development] graham_h:
can I ask does this effect the GPS settings AT ALL

Last rooted kernel I used stopped mine from working

Thanks

Graham
[Galaxy S II Original Android Development] WarriorZ:
hi guys.. want to ask

i had just flash from 2-3 kernel, speedmod t27, niphine 2.1.2, mirage and niphen 2.1.3 again..

now I want to go back to speedmod again but in t29.

is there some possibility of instability and error occur if I do something like this: (change kernel regularly) flash with odin ?

Im using stock ROM.

I just want to try the most optimized version on my phone.

thank you.
[Galaxy S II Original Android Development] lynx2k50:
Hey Hardcore.

Is it usefull to build up the kernel on the new AT&T sources?

There are more actual and maybe the drivers are newer.

Thanks for your work.
[Galaxy S II Original Android Development] Auridran:
You can flash to your heart's content, and it's not going to affect anything.
[Galaxy S II Original Android Development] WarriorZ:
so nothing I must do after install ? wipe cache or wipe dalvik cache or reset battery stats in CWM is not necessary to do ? is it right?
[Galaxy S II Original Android Development] Weste90:
sry guys but could anyone please define me what this change is:

- Compiled using Linaro GCC 4.5 2011.09 toolchain

?

greetz and thanks
[Galaxy S II Original Android Development] aqualeris:
Reset battery stats would be ideal after flashing every new kernel/rom. The rest is not necessary.
[Galaxy S II Original Android Development] dzontra11:
First freez after couple days...:-(
[Galaxy S II Original Android Development] dzontra11:
Something i's wrong here....i check my battery stats ...it was 37%....but one hour later it was 39%....how....????
[Galaxy S II Original Android Development] nikzDHD:
You'll need to recalibrate battery.
[Galaxy S II Original Android Development] dzontra11:
Nope..i done that...
[Galaxy S II Original Android Development] uronfire:
can this kernel be used with the latest k13 2.3.5?

thanks
[Galaxy S II Original Android Development] mbutandola:
I understand that BLN support will not be implemented and I respect hardcore's choice but is there any kind of script that one could flash over the kernel to get BLN working? I know the is ragemod but it doesn't give me as much satisfaction as this kernel.

Cheers.
[Galaxy S II Original Android Development] nikzDHD:
Yes it can, as mentioned before can be used with any Samsung based rom stock or custom. But not with CM7 and MIUI excluding galnet.
[Galaxy S II Original Android Development] donalgodon:
Why is SpeedMod smaller than stock kernel?

Just noticing that the stock kernel is 8.0MB where this one is 7.15MB.

Basically, I'm wondering what accounts for the reduction in size of the kernel itself? I assumed that adding the root features (bb, cwm, etc.) would make the file size larger.
[Galaxy S II Original Android Development] WarriorZ:
you can flash alternative hell cats kernel.. it is based on hardcore and added BLN feature.
[Galaxy S II Original Android Development] karl999999:
what about custom bootanim? its not working now

should it work already? then how?
[Galaxy S II Original Android Development] mbutandola:
Thanks. I wish I could just flash the feature giving me more flexibility.

Any link to that kernel?

Cheers.

Edit: never mind I've found the thread. But seems that the dev has more important things to do at the moment.
[Galaxy S II Original Android Development] jetshinoda:
actually u can just flash it via CWM app and that's it...nothing further need a do..

why do u need to wipe cache or dalvik anyway everytime u flash a kernel? it's a kernel not a ROM :D

and battery stats...just install battery calibration to do that :cool:
[Galaxy S II Original Android Development] Weste90:
could please someone tell me :( ?
[Galaxy S II Original Android Development] alcurtis93:
It just means he used a different toolchain to compile it. Research linaro if your that bothered
[Galaxy S II Original Android Development] kersh:
setcpu doesnt work on this kernel?

Is not possible to low the voltages then?
[Galaxy S II Original Android Development] kpmkat:
Voltage change / overclocking / Governor change is not supported on this kernel.
[Galaxy S II Original Android Development] rodeo_calling:
Is the t40 bet better than the stock Ki3 kernel? I'm currently using it with kh3 and love it but since I'm planning on upgrading to Ki3, wanted your input.

Cheers
[Galaxy S II Original Android Development] donalgodon:
No disrespect to hardcore, as this kernel has some great tweaks, but I flashed the stock kernel for the sound improvements.

If we can maybe have T-41 with those integrated as well, I'd be very happy.
[Galaxy S II Original Android Development] rodeo_calling:
So are you saying that the stock ki3 is overall better than t40 or just the sound part (think that's it right)?
[Galaxy S II Original Android Development] donalgodon:
Well, for me, the sound is a pretty big deal, so it tipped the scale. I appreciate the visual tweaks in SpeedMod quite a bit, and it was a difficult choice for me to make.
[Galaxy S II Original Android Development] nikzDHD:
+1 I don't know what Samsung have done but sound is improved! Now I can happily listen to music from this phone, maybe it'll improve over time as well. I'm sure it's not a placebo effect.

This new firmware paired with Rockbox blows!

Hopefully Sammy release sources so HC can incorporate.
[Galaxy S II Original Android Development] dzontra11:
New firmware...?Which one?
[Galaxy S II Original Android Development] nikzDHD:
KI3 2.3.5 is the newest.
[Galaxy S II Original Android Development] dzontra11:
From Kies?
[Galaxy S II Original Android Development] nikzDHD:
From XDA :D

Stock and custom, leaks already available not officially via kies but stable!
[Galaxy S II Original Android Development] dzontra11:
Tnx man a lot.
[Galaxy S II Original Android Development] DarkDvr:
So K1-T40 will work well with KI3 2.3.5, right?

VillainROM 3.0 in particular.
[Galaxy S II Original Android Development] nikzDHD:
Yes sir see my sig :)
[Galaxy S II Original Android Development] douglatins:
About that sound improvements, it goes for what combination of kernel and ROM?

Can i get them with villainRom + a kernel i don't know about?
[Galaxy S II Original Android Development] rodeo_calling:
So the improvement in sound is that great huh? Can't wait to try it then, and hopefully newer versions of speedmod will include it, after Samsung releases its source.

Thanks for your input mate.
[Galaxy S II Original Android Development] obionenairobi:
So you are using the KI3 stock kernel ?

How does this compare to T40 in battery life?
[Galaxy S II Original Android Development] bu2askoor:
I know that many has it working fine, but for me wifi goes nuts and eats up battery with this kernel.. A stock kernel saved me (for now)
[Galaxy S II Original Android Development] nikzDHD:
CF root which is based on stock. Well just flashed it last night my first stock kernel in months, so will test today regarding battery life.
[Galaxy S II Original Android Development] rodeo_calling:
Offtopic but since we are talking about the sound improvement, using cf's Ki3 will not affect the sound right?

No offence to hardcore and his topic.
[Galaxy S II Original Android Development] Auridran:
His has stuff injected into it as far as I know, therefore no sources are needed. As a result, the sound stuff will still be there.
[Galaxy S II Original Android Development] iru786:
Does this work fine with DarkNight V4 rom?
[Galaxy S II Original Android Development] nikzDHD:
Yes give it a try.
[Galaxy S II Original Android Development] douglatins:
This one?

XX_OXA_KI3-42: 2.3.5, CF-Root v4.2, SU 3.0, "insecure"

?
[Galaxy S II Original Android Development] momyc:
I just did it today going from 2.3.3 to Frankenstein 2.3.5 (no-wipe)+this kernel( XX_OXA_KI3-42: 2.3.5, CF-Root v4.2, SU 3.0, "insecure" ) and so far so good.

[Galaxy S II Original Android Development] pedrolopes665:
Hardcore speedmod bootanimantion guide.

Change bootanimation in speedmod kernel is not as simple as in others, but is possible.

Lets go:

your bootanimation MUST HAVE FINITE REPEAT VALUES, otherwise you will be stucked in a beautiful boot loop.

*What is this?

Open your zip and see the txt file. The number after all "p" must be HIGHER than 0. It means how many times this part will repeat, and 0 is infinite

0- Make a nandroid backup

1- Pick your desired bootanimation.zip and make two clones. Rename them to ODEAnim.zip and sanim.zip

3- Move the three zip files to /system/media

4- Go to /system/bin. Backup and delete the file samsungani. Rename the file bootanimation (this file you find in this folder; it ISNT your zip file) to samsungani.

Reboot and be happy.

Edit: if u want to change the boot sound, the file is /system/etc/poweron.wav
[Galaxy S II Original Android Development] karl999999:
can somebody expand on that?

did i miss a statement from hardcore?

at least i like to know why he wont support custom bootanim :-)

if there was a statement already, please direct me to the post ...

[Galaxy S II Original Android Development] hardcore:
Wifi tethering works fine for me on T40. I use it all the time also. The problems you are facing could be related to the ROM.
[Galaxy S II Original Android Development] Amokbunny:
Hey hardcore,

there's one thing I now finally figured out:

As you probably know, some (few) ppl (including me) experience constant wifi disconnects when using a KI3 rom.

I tried different modems etc, all with no effect. At the weekend I played around with kernels, and who-hoo, that solved (at least my) wifi problem.

A kernel for example that works is his' beta kernel: http://xdaforums.com/showthread.php?t=1275381

Do you know what's the difference? Updated initramfs/scripts for KI3 or so? I'd love to run my sgs2 on you kernel again, but I need WiFi...

Could you look into it? Would be highly appreciated :)

Hey guys,

please help me, I do not post a lot but I am a great follower of this forum.

I've been using the t40 for a couple of weeks and it goes great to me.

Now i want to upgrade the firmware to 2.3.5 and there is no way that I can flash the SpeedMod kernel in KI3 rom.

I have tried using Odin and CWM as well, but it always freeze in the boot screen, so I have to flash de cf-root kernel again and again

I've just tried with t41, that it seems to be more compatible with 2.3.5 but I have exactly the same issue

What I am doing wrong?

I didn't read the entire thread (because it is two hundred pages long http://media.xda-developers.com/images/smilies/frown.gif) but when I discovered the SpeedMod World, I assure you that I read at least a hundred pages. Now I just read about 10 pages back and I saw that there is people using 2.3.5 and t40, so I realized that they are actually compatible

I flashed the KI3 with Odin and re-partition selected, so I assumed that the wipes are already done

any clue?

please?
[Galaxy S II Original Android Development] ql4y3r:
When finished the rom flash, then flash immediately the sm kernel, and not the cf kernel. . .;)
[Galaxy S II Original Android Development] PatoPoroto:
thanks for the answer, but it didn't work either
[Galaxy S II Original Android Development] ql4y3r:
Reflash the rom once again and then the sm kernel. I've done so and it work fine.
[Galaxy S II Original Android Development] PatoPoroto:
do you mean twice in a row?

I just flashed KI3 (with re-partition), then immediately the SMKernel....

nothing....

5 minutes freezed in the boot screen

now I am recovering the nandroid

(I have to say that I've flashed a lots of kernels and roms before, not a noob problem i guess)
[Galaxy S II Original Android Development] ql4y3r:
No. Just once. But I see the reflash, it won't help. Maybe another colleague could help for you. (and sorry my english)

thanks anyway

this is really weird since I've flashed roms and kernels a lot of times, and seems that other users doesn't have any issues
