Just because you didn't find undervolting good and didn't get much JUICE out of it then it will be the same for everyone. As much as you don't like the undervolting feature, there is also on the other end of spectrum that find it great and cant live without it.
[Galaxy S II Original Android Development] briko78:
Hey :-)

Are you using the stock KG3???

Thinking of trying it... Have some time this afternoon *lol*

Bye

[Galaxy S II Original Android Development] umair9001:
i didn't say that i didn't like it, the main reason for instability in the kernel is cause by undervolting, hence it was probably removed..for the rest i think HC can answer to us.. :)
[Galaxy S II Original Android Development] rdy2go:
I wonder if real battery usage is lower now or is it just hiding android os usage because some counters are disabled.
[Galaxy S II Original Android Development] Vulpix:
Hrmmm, that could be why AOS is not there too... :D
[Galaxy S II Original Android Development] Vulpix:
Okay incoming stupid question, since this kernel mod is based off 2.3.3, why does it work without any issues (so far) on KG3? I don't get it. I flashed T8 on KG3, and it works fine.
[Galaxy S II Original Android Development] ObihoernchenDE:
Because there aren't big kernel changes. You don't need a new kernel for a new Android version. If the change is minor.
[Galaxy S II Original Android Development] Vulpix:
Big change like from 2.2->2.3? 2.3.3->2.3.4 is considered minor then?
[Galaxy S II Original Android Development] kryptoner:
You can directly download it using your phone with xda-app, CWM flashable kernels are more convenient to flash.
[Galaxy S II Original Android Development] gschot:
It is a 'smart' phone... You can download kernels and/or other files directly from the internet with it, without the need of a pc.
[Galaxy S II Original Android Development] aqualeris:
Ah I see.. Thank you guys so much. I guess flashing will be much easier for me now. :o
[Galaxy S II Original Android Development] djvdorp:
It will also work without wiping cache and dalvik from my experience.

Sorry for the lame question, but is there any reason to DO wipe cache and dalvik after installing new kernel?
[Galaxy S II Original Android Development] KurskS:
How did you get Speedmod to work with Galnet MIUI, I installed and the phone keep respring all the time after 10s, and wifi is not working...
[Galaxy S II Original Android Development] manudevil:
Does this kernel work wit SGS I9000 ? Because it seems that there is no new release for JVS, for example...

Thanks in advance.
[Galaxy S II Original Android Development] KurskS:
No ofc not:D
[Galaxy S II Original Android Development] djvdorp:
AFAIK not.
[Galaxy S II Original Android Development] bunglebp:
can this Kernel be installed alongside ninphetamine kernel?

Appreciate if someone could PM me the answer...Many thanks

[Galaxy S II Original Android Development] nikzDHD:
No how can you install 2 kernels!

On a side note after calibration and discharge on my second cycle awesome life, 10 hours 15mins, 85% left 30mins screen on time 3g on all time.

Does facebook decrease my battery life even though I have it closed?

Or should I sign out from facebook?
[Galaxy S II Original Android Development] djvdorp:
T27 vs T40

Hmmm, to me it seems that T27 battery life is still the best. Have also tried T32 (good too), T39 (a little less good) and T40 (same battery time as T39?).

Just having a doubt over using T27 over T40, as T27 is pretty old nowadays.

Any reason to use T40 over it? Are those update2 tweaks in T40 that great?
[Galaxy S II Original Android Development] eranyanay:
Of course it does, as it listens in the background for new updates/received messages
[Galaxy S II Original Android Development] chiggah:
Yeah but I turned OFF Notifications in facebook. Does it still affect?
[Galaxy S II Original Android Development] Остап:
Yep of course ;)
[Galaxy S II Original Android Development] Auridran:
Yes it does because as far as I know, it still listens for the things that it would notify you about, without notifying you.

According to BetterBatteryStats though, it barely uses any wakelock time, so it's quite a small drain on battery.
[Galaxy S II Original Android Development] flo2lacanau:
Please HC, come home ... :confused:

Can you update your kernel speedmod for I9000 ...

2.3.5 is release since 2 weeks and K15I for SGS1 don't work on it ...:(

I hope read you soon ...
[Galaxy S II Original Android Development] Neo.:
I'm surprised to see everyone having great battery life except mine even though I'm a moderate user. It can barely last 20hours with little wifi usage :(
[Galaxy S II Original Android Development] Auridran:
How much screen-on time is that? What do your wakelocks with BetterBatteryStats look like? Have you removed/frozen all bloatware? All the apps relating to WiFi sharing seem to drain the battery in a harsh manner, even when it's not being used and never has been used.
[Galaxy S II Original Android Development] Neo.:
I can provide you everything I've got

I've been charging once per day in order to reach that battery stats ice got auto sync for gmail and juice defender enabled accu weather for which I reset the interval to 24hours.

Im using cognition and reflashed kernel disabled fast dormancy as well :(
[Galaxy S II Original Android Development] nikzDHD:
Animated weather is keeping your phone awake big time and Savan, remove those and notice the difference as a starting point.
[Galaxy S II Original Android Development] chiggah:
Same I'm getting terrible battery with light use too - Cognition 1.5.1 with T40 - pretty standard apps nothing too heavy
[Galaxy S II Original Android Development] Auridran:
This. Those aren't the only two though.

After 11 hours the app that has wakelocked the most for myself has wakelocked for less than 3 minutes.

EDIT: To the post above, that doesn't look like terrible battery life to me, especially with WiFi on the entire time. One thing that is odd though, is you have a significant amount more awake time than screen on time without a lot of wakelock time.
[Galaxy S II Original Android Development] hEEGy:
Can you stop posting about this phone in this thread please? Just PM him...
[Galaxy S II Original Android Development] chiggah:
How do I use WiFi when needed ? Like only have WiFi turn on when the screen is on
[Galaxy S II Original Android Development] Auridran:
In the WiFi settings, hit menu, then go to Advanced and choose WiFi sleep policy. Choose the applicable option.

Depending on how often you turn your screen on, having WiFi turn off when the screen is off may or may not save power. Also depends on how often your data gets used, since WiFi should use less power than 3G for transferring data.
[Galaxy S II Original Android Development] chiggah:
Ahh forgot about that - after I've switched ROMs. What about 3G? Can I turn that off during sleep too ?

I have another issue though if you can help. I have a battery reading % problem if anyone can explain. Could it be a calibration issue ?

Charged to 100%

Unplug

Displays as 96%

But the charges increase to 97-98%, over time after being unplugged

But its not a huge problem because I just unplug and plug it back in till its truely charged 100%

Dont have this problem with Ninphetamine kernel but Speedmod is causing this issue (if i recall)
[Galaxy S II Original Android Development] Neo.:
Done removed those two.

Can you suggest me some good weather apps that won't eat my battery? I'm even fine with apps that check for every 24hours thanks for your help mate will hit thanks when I get on pc
[Galaxy S II Original Android Development] Auridran:
Fancy Widgets doesn't seem to drain my battery, even on a half hour refresh.

[Galaxy S II Original Android Development] nikzDHD:
It will work currently using it with VR2.5.
[Galaxy S II Original Android Development] rodak:
This is true, this graph only updates when there is a change in battery level.

So if you charge to 100% and let it idle you wont see any useful info until the battery level goes down to 99%, then again you wont see any new changes in the graph until battery drops to 98%, and so on and so on.
[Galaxy S II Original Android Development] celiocalves:
@Hardcore can you say what have changed in Wifi and sound? :confused:
[Galaxy S II Original Android Development] Остап:
Yep/ It's true. I see this issue on my phone. If you look at Spu Spy at the same time - you will see 80-90% of deep sleep ... ;)
[Galaxy S II Original Android Development] KennyLegend:
Freeze maps, uninstall animated weather and savan (whatever that is). they are keeping your phone awake and draining ur battery.

Seriously, come on heard of something called reading sorry if I sound rude but this has been asked near twice now in relation to your first question! Only a few posts before this!

To anyone else who asks this yes it will work with any Samsung based rom. To flash use CWM manager easily found by searching or darkys tool!
[Galaxy S II Original Android Development] Zanr Zij:
Normal! Many time I can do that. If you show me Battery Motitor Widget Pro History, I will show you why :).

If you can do like that when you battery about 50%, it's very impress :)

No problem with his screenshot! If your batt @ 100%, you will always see screen all time :). Immediately drop 99%, there is a changing :D
[Galaxy S II Original Android Development] benalejandro:
Get rid of juice defender, it uses more battery than it saves, I used it for a very long time (ultimate edition) and as soon I stopped using it, I noticed better battery life.

You can read about it in the betterbatterystats thread, if I'm not mistaken.

Hi guys

I am on Cognition 1.5.1 with Speedmod T40 and experiencing high Android OS usage which is chewing up my battery. The phone was pretty much on idle/light use and I do not have many applications installed - just basic ones like Facebook, Watchdog, betterbatterystats, battery monitor widget, imgur, Skype, Talkbox, Viber, Whatsapp.

I have also just calibrated the battery by charging full, calibrated with app and now discharging

Anyone able to help? Something is definitely going on and im unsure what it is. Please let me know if you require more screenshots
[Galaxy S II Original Android Development] BrandoHD:
You have to post the partial wakelocks and you have to use your phone normally for awhile to get a proper reading, the phone is at 98%, that's not enough info.

Perhaps charging fully and leaving the phone overnight.

[Galaxy S II Original Android Development] chiggah:
Could it be an AOS bug causing my battery drains? I thought 2.3.4 fixed it? I dropped from 100% to 88% within 2 hours with minimal light usage to no idle.

Whats the solution here ? Try VR 2.5 with Ninphe 2.1.3 or speedmod ?
[Galaxy S II Original Android Development] BrandoHD:
Charge the phone fully and let it sleep, it's easy to see that the phone awake time is equal to the screen on time from your screenshots, the battery level has no choice but to drop quickly when you are using the phone.
[Galaxy S II Original Android Development] chiggah:
Also I have turned off my WiFi policy to off when the screen is off, but it's still turned on in Battery Usage stats ?
[Galaxy S II Original Android Development] rodak:
That my friend is f****g VIBERS fault, this lovely, yet stupid app keeps the wifi on at all time. They call it a feature, but I rather want to control my wifi sleep policy myself.

Please email viber support and complain, I have already.

[Galaxy S II Original Android Development] devilkin:
That is a bad example. Im not trying to say that the android OS doesnt have a battery drain problem in some cases, im just pointing out that I have seen WAY too many people make this mistake on here

People have to understand how percentages work. If you divide something into segments then the sum of the percentages HAVE to add up to 100% Your android OS usage is high because u didnt use the phone at all I assume because of the very low display use (you didnt post a shot of the awake times). If everything else (apps and display) is low because you didnt use the phone, it means that the only other thing left (android OS) WILL be high. It is just simple maths.

Lemme give a simple example: Take an apple (you battery). Cut a quater of it off (the 24% battery u lost). Now of that bit you cut off, you decide that you are not very hungry (you didnt use your phone a lot/low display use) and only take yourself a tiny bit (16% / the batt use of the other stuff). Whats left of the bit we cut off is for me (im android OS / 84%). Now just because I had 84% of the bit we cut off doesnt mean I'm a greedy pig, you only took 16% for yourself so I ended up with the rest. See what im getting at?

A percentage is not a value. Its just a percentage OF a value.

Once again, im not saying theres no battery drain, just saying a high percentage on its own doesn't imply it

EDIT: just have to add this example my friend just gave me:

that's like going "omg idle process eating my cpu"

:P
[Galaxy S II Original Android Development] BrandoHD:
Dude you need to relax and stop pushing that panic button, up to now you have not posted any screenshots that should cause any alarms.

Does anyone know why the kernels in the latest leak ROMs don't include the patches made in the Samsung Update2 sources? (if they don't)

I would have figured that they'd be rolled into the kernel automatically.
[Galaxy S II Original Android Development] eranyanay:
When does this kernel is going to support the ntfs file system, such that is in sayiahkernel?
[Galaxy S II Original Android Development] donalgodon:
Isn't that a step down from ext4?

From my perspective, it is.
[Galaxy S II Original Android Development] brack11:
So, as I understand I don't need any undervolting our setcpu stuff with this kernel and it will still get the best battery life?

Sent from my GT-I9100
[Galaxy S II Original Android Development] AndreiLux:
***** please. You ain't got nothing on my AOS! :p (see below)

I think this will be the 4th or 5th time I correct people like you here.

That's not how percentages work. You do not take a part of a pie or an apple. There is no such thing as a whole apple to take something from. The apple does not exist.

What exists, are absolute values. Every process uses a CPU time or for the case of phones the electronics have some ampere-meter or some algorithm to measure or estimate the current. It turns that into some quantized value that corresponds to the mAh used by the process/call/physical activity of the phone. If you use another ROM like MIUI you can actually see this power metering.

The apple gets created only then, because only then you have the sum of all power usage, and out of that every process gets its percentage calculated and attributed. There is no such thing as a "rest" in percentages because percentages themselves are absolute. You cannot calculate a percentage from other percentages like you did, that's grade school mistakes and you are wrong here.
[Galaxy S II Original Android Development] eranyanay:
Im having a weird behavior

I already had my two battery cycles and now at the third one.

I unplugged my device from power 9 hours ago and had a light use with it. I've been watching the percentage and it was going on pretty fine

An hour ago it was at 74%, and memory use was 600 used.

Now when I came to use it, I found out it reboot itself probably as only 300 was used.

Percentage is at 71, but the battery info is showing wrong data, as the time on battery is just 5 hours instead of 9, so its like it forgot about the last 4 hours...

I did a correct calibration.

Here's the photo:

[Galaxy S II Original Android Development] Auridran:
I can't speak to the random reboot, but very often after rebooting my phone the battery stats that were there will have the wrong time on them. I don't think this has anything to do with the kernel.
[Galaxy S II Original Android Development] mynamesteve:
See that big ass vertical drop?

did you flash something or backup with recovery?
[Galaxy S II Original Android Development] nikzDHD:
It can happen when the phone freezes and such and reboots. You'll end up with a massive drop. Not sure what causes it but something, can happen at random I've had it happen to me a couple of times.

When flashing etc you'll notice drops like that as well but not as big.
[Galaxy S II Original Android Development] eranyanay:
I appreciate your help.

The phone was in standby..with no use at all.

I wasn't flashing anything or messing with the recovery.

I didn't even used the phone when it happens, thus I didn't even notice..hehe

So now that you have some more information, what do you think? Is it kernel related issue or just some unexpected situation that caused the device to reboot?
[Galaxy S II Original Android Development] Auridran:
Opificio. The only thing I don't like about most custom fonts is that bolding doesn't seem to work properly. A lot of fonts seem to bugger up in Gmail as well.

I'm going to have to agree with this. If there wasn't some issue with my Android OS, the slice it was using would be far lower, even if I didn't use the phone at all. The percentages of everything else would just go up in relation.

I used the phone many times over the course of the day before taking that screenshot, for short things like text messages, and ended up with about 20 minutes of display usage in that shot. I played around with my phone a lot later on, and at around 13 hours and an hour and a half of display time, my Android OS was still at 75%.
[Galaxy S II Original Android Development] nikzDHD:
Without any logs hard to even guess, and again can't replicate it. Forget about it and don't worry about it. Just carry on using the phone. Most likely a random reboot or freeze caused by something not being right.
[Galaxy S II Original Android Development] Auridran:
Today's usage after freezing Email (since I didn't use it anyway) and a couple more pieces of Samsung bloatware, with similar usage to yesterday:

Half the battery drain, much lower Android OS usage at about 4 minutes per hour instead of over 15.
