in my sig, using kg5, yeah I do :p
[Galaxy S II Original Android Development] Radikaal:
perhaps check if you have wakelocks? try another radio?

its all about how you use your phone. if I just use phone for calls sms and some news/email syncing 4-5 times per day and say only got screen on for 2hours in total I can get 4d+ on the battery. but with my normal usage as in my post 5-6hours of usage with screen on I "only" get 1½-2d, but when i use phone heavy that may be standard to some, to play games, watch youtube or just surf around alot / have music or chat app in background preventing phone to sleep or just having screen on for more then 6hours , battery normally lasts not even a day no matter what kernel/Rom.

if you have more then 0.5% battery drain with data off /hour when screen is off you most likely either have some app as a wakelock or should consider another radio, or phone just doesn't go to deepsleep.
[Galaxy S II Original Android Development] ram3n:
My first current conclusion :

The best way to calibrate your f*** battery is definitely to do it manually.

Just delete batterystats.bin in data/system, after full charging (with Rootexplorer or another app)

Then, use it until to 90%, and full charging.

That's all ATM.

Why ?

Because, I've just noticed that Battery Calibration App doesn't always delete this file. Ya, sometimes, It works, but sometimes It sucks. I don't know why, but seems to be related to some SU version and permissions' bugs...

Hope it could help some of you.
[Galaxy S II Original Android Development] morg01:
Yeah this 20hr + battery thing has me wondering what I'm doing wrong too, I've never seen my battery last more than 10/12 hours . . but that being said I have three email accounts syncing every hour + twatter + Farcebook (mis-spelling intended), then when I'm at home I'm on wifi . . so maybe my normal usage will never see 20hrs?

Thing is looking at whats eating my battery I see a high OS percentage . . is that normal? see attached screen shot, sometimes my OS usage is way higher than screen on time

Dude, let attach a "wakelocks" screenshot with Betterbattery App.

I'm sure there are many apps which consumes and drain your battery when youre screen's off. :cool:
[Galaxy S II Original Android Development] BrandoHD:
Very weird, why, "gokhanmoral" has a auto calibration thing integrated into his "Siyah" kernel whereby you just have to leave your phone attached to the charger overnight and it will be "auto-calibrated" so to say calibration is not needed and then implement features in the kernel that does it automatically is....
[Galaxy S II Original Android Development] ram3n:
Dude, as written by gov :

Q: do I need to recalibrate the battery?

A: You don't need to calibrate battery for SGS2. Thanks to Entropy512 to pointing out that our device uses MAX17042 which is specifically designed not to require calibration.

The fact is when your battery runs like a hell and is going crazy, what sould we do ? Leave it like this and look him dropping superfast ?

Just be serious please !

The only solution is to a (correct) manual calibration, as I said above...

Auto calibration is a crap feature. Don't you know that leaving your phone on charging all night kills bit by bit your battery ? ...

No matter what the others say, just try first by your self !
[Galaxy S II Original Android Development] morg01:
what is this better battery app you speak of, I can't seem to find it on the market?

[Galaxy S II Original Android Development] mariotme:
hey hardcore

i got a general question regarding kernel's.

What is it that kernel developers say that the AOS drain has been fixed in their kernel? i mean have you looked into any of these kernels?

thanks for you time and superb kernel!
[Galaxy S II Original Android Development] dan@msx:
I can confirm - this works on XXKI4 as released by Intratech earlier....
[Galaxy S II Original Android Development] KennyLegend:
Its not fixed (in siyah kernel) or any other Linux .14 sources. Just merely masked. Aos reports low but battery life isn't any better. Check out the AOS bug thread by andreilux
[Galaxy S II Original Android Development] BrandoHD:
If you took the time to read, you would realize that I was responding to someone else and their comments about a particular kernel and calibration and auto-calibration, that is why I quoted "them", but in your haste to disseminate the knowledge that you want everyone to know you possess, you completely ruined it as you did not take the time to understand why the statements were being made and you probably didn't understand why I quoted the post of another member, some more reading and a lot more

understanding

is in order for you.

No where did I ask a question on calibration or the likes as I do not require any information on it, so why you are quoting me and answering a question that was NEVER asked has escaped me, in the meantime your post will hopefully have meaning to someone else who may require that information that you were so eager to spread, but it has absolutely no meaning to me.........
[Galaxy S II Original Android Development] ram3n:
And here we go...

As I expected, Email processus is draining a lot your battery, SyncAlarm and FB are sucking too.

You have now the choice to delete them or not.

For me, I don't use them at all, and can simply use an "ersatz", i.e checking my email or FB on browser :)

[Galaxy S II Original Android Development] seburn:
On second run post calibration I got 1 day and 15hours with 1.5 hours of screen time.

I am running KI3 frankenstein build with KG5 modem.

I stay in South Africa :)

One thing I want to point out is that I don't have 3G data most of the time (<1%) but wifi is on (this uses less battery). I don't think anyone getting +1 day has 3G/HSDPA data permanently on.

For calibration I used the battery calibration app -- charge to 100% run the app

restart and drain till the phone turns itself off. Leave it off and charge it until full.

[Galaxy S II Original Android Development] oyebto:

[Galaxy S II Original Android Development] Dark Emotion:

[Galaxy S II Original Android Development] nicolasf:
I have yellow tint using K2-3. Is it possible that this has been introduced when the original source changed (K2-x)?

To be fair: I was using Siyah before, and before that Ninphetamine and they were normal (no yellow tint).

It's pretty evident on Android Market (grey screens) as usual, and even on white or light grey images.

Anyway, will test better tomorrow for battery usage =).

I'm also curious on this one. Tried searching but found nothing.

Thanks!

Same here. Yellow Tint is back.
[Galaxy S II Original Android Development] nhtr1973:
Hi HC. Thanks for your kernel. Just 1 question! After I flash k 2-3 with odin. at start up, there is yellow triangle. I extracted the zimage, copy to root sd memory card... flash it with cwm, still could not get rig of that triangle. Can you help me plaese. Thanks
[Galaxy S II Original Android Development] Jonjungle:
Is this your first time flashing a Kernel? Reason I'm asking coz by flashing Speedmod you would have automatically "rooted" your S2 and hence the triangle will come up. There are options to remove that Yellow Triangle either by using a JIG or a little search on XDA forums for a workaround.
[Galaxy S II Original Android Development] arkerio:
YES I DID :)

itz nice :D
[Galaxy S II Original Android Development] KennyLegend:
You need to flash a stock kernel with odin first, then extract zimsge of speedmod and flash that via cwm app.
[Galaxy S II Original Android Development] formidabilus:
there is an update from k2-2 or I just need to flash again with odin the k2-3 version?

K2.5 is best kernel out there. I have tried every nearly kernel

Nothing compare to speedmod. At 1200mhz I got 4765 quadrant. Now if you want to get that kind of results on other kernel. Then you have to overclock to 1600mhz.that how fast it. I can write alotmore. Its best for u to find out

It must admit that your kernel rocks since the beginning : very simple to use, no UC or UV needed.

It was using Siyha's kernel a while, but always trying to get better undervoltings settings after every beta's flashing, so that I was finally tearing my hair out.

So, let's back to Speedmore, simple as ever.

Althought quadrant isnt very good benchmark tool i would say, try more updated apps like antutu, smartbench 2011, cf-bench etc. Althought one thing i noticing with k2-6 (flashed trough kitchen on revolution) it doesnt have OC, is this something you added in a update and the initial k2-6 didnt have it?
