Hi Ivan, honest answer? Not a lot, and I will explain you why:

This mod creates a swap file (I believe around 500 MB) on the internal phones sd card. So far so good. But as you know, sd memory ages with every write access to it. And swap does a lot of writing, so it is very likely the lifetime of your phone gets significantly decreased. Of course the wear levelling algorithms for sd memorey are quite good and try to avoid this for a as long time as possibke, but... For me, this is the reason to not use it. I do not want to have a bricked S3 due to that.

The alternative would be to create the swap file (or partition) on the external sd card, but even with class 10 cards it does not always feel fast enough to avoid lagging.

So all in all, I am not using it and also would not really recommend it unless you have a very specific scenario that justifies the usage.

Exactly, it is not provided as a stand-alone mod.

But, I always offer to guide people to convert the Boeffla-Mod to a "crt-off" only mod. This is quite easy by using a zipping tool like 7zip and anybody can do it. If interested, pm me.

Thank you, very nice and detailed feedback. Appreciated :D

Hey guys I'm getting bad battery drain while my phone is supposed to be sleeping, I can't understand what is keeping it awake. Can anyone understand what it could be that is stopping my phone from sleeping? :/ cheers. I'm using wanam lite 4.7 and the newest boeffla btw.

Re: [KERNEL] [Samsung JB] Boeffla-Kernel 2.7.1 (07-02-2013)

I'm on XXEMA2 stock and newest stable release kernel. I followed what mccrane posted gave my CPU and GPU a medium undervolt but reduced the CPU Max to 1.2 and wow suddenly its like this rom has had a rocket shoved up its backside lol. Its become noticably faster with about the same smoothness as before. Battery obviously too early to comment on.

Hi, looks like you were listening to Music for 20 minutes?

Audio Out is typically an indicator for that.

Hi all,

just to let you know, I moved all kernels from Dropbox to my own new web space (after Dropbox suspended temporarily my account due to heavy traffic).

So, all kernel download links are up again.

Re: [KERNEL] [Samsung JB] Boeffla-Kernel 2.7.1 (07-02-2013)

Nope, that's the thing though I haven't listened to any music or anything like that.. my phone has been asleep and the only thing I've been using it for is to text on whatsapp while I was playing the new dead space haha.. so that's why I can't understand what's doing it as it's definitely not music. :S
[Galaxy S III Android Development] andip71:
Hm, then I can only recommend you doing the following:

- no undervolting

- switch off (for a test) the three tweaks (system, ext4 and sdcard)

- reboot and wipe cache and dalvik cache

- make sure you have no "weird" scripts in your init.d folder

If the issue still persists, send me a debug info file created in the boeffla-tweaks app via email the support address. Then I can have a look.

Re: [KERNEL] [Samsung JB] Boeffla-Kernel 2.7.1 (07-02-2013)

I have add a big issue this morning concerning battery (see my screenshots)

Have done a intensive usage of the phone and he was hot like hell... was having 23% battery and when i removed the battery and putted in back i was only having 13%!!!

Its maybe kernel related, but i would like to have your advice.

Thanks

Edit: dont know why but cannot post screenshots... sorry

Omegas V40

Boeffla 2.7.8 beta

Sent from the frozen Haute Savoie... French county... hehehehhe
[Galaxy S III Android Development] andip71:
Hm, without screenshots not a lot I can do.

The thing I can say is: Removing the battery and putting it back in always results in "glitches" in the percentage display as the internal logic gets crazy until next loading cycle.

Apart from that, I see you are on Omega rom. I would make sure the rom does not use own scripts in init.d and would also not undervolt if you did so.

[Galaxy S III Android Development] cybdani:
Some people is having the same problem but with STOCK kernel and STOCK ROM also without root. Appears Audio_Out on first place. Nothing related to Boeffla Kernel.

What rom are you using?

You can check if multimedia process is active for some hours. Then the only solution is to format ext sd card again.

Re: [KERNEL] [Samsung JB] Boeffla-Kernel 2.7.1 (07-02-2013)

AndiP, is there chance cpu and gpu undervolting may cause lag?

Sent from my GT-I9300
[Galaxy S III Android Development] andip71:
Yes, absolutely.

If you undervolt down to a point where your CPU or GPU do not work rock stable anymore, it can come to lags.

Honestly, I do not do any undervolting anymore for a long time already. I prefer the more stable behaviour of my phone over maybe 10 or 20 minutes more runtime.

Andi
[Galaxy S III Android Development] EViollet:
Undervolting has little or no impact on the battery life.

It does, however, lower the CPU temperature. At that's the whole point of it.

[Galaxy S III Android Development] andip71:
True. But on the risk of getting instabilities. It is the personal trade off everyone has to decide for himself.

Hi Andi

2.7.1 works very well---awesome

Big Thanx to you

Note:for those who have battery drain or so on...it is definitely not the kernel.....maybe wakelocks and other stuff

there gives an app in the market...i recommend it highly...."ALL-IN-ONE-TOOLBOX" you can manage cache---add to startup...

boot speedup...this option you can disable apps and system apps from startup.....and many more

try it yourself :)

cheers Dan
[Galaxy S III Android Development] rensen:
After one day trying the last version beta and stable 2.7.1 i told here that BY NOW is the version that drained my battery more fast that the others.

Trying more.

THANKS

Wish happy week-end to all.
[Galaxy S III Android Development] danmaman:
hi rensen

look at my 2 screens where's a battery drain?
[Galaxy S III Android Development] rensen:
Nice screen shot: 2 days and 6 hours? look good...but youneed to add more data..2g, screen brigthness, live walpapper (like me) color of screen, battery saving options, anims of menus, etc.

In my case, i believe that a update of a live wallpapper make me draind the battery ( the live wallpapper ) trying more...

THANKS.
[Galaxy S III Android Development] danmaman:
ok

here some tipps and my handling with my phone...

-at first boeffla kernel.....

Ext4 tweaks--->off -------SD READ off----boeffla tweaks ON......rest default.....

governor/scheduler---->Pegasusq (Moderate)/ BFQ

MaxFreq.1200

CPU/GPU.....-25%

now settings phone (wifi/data/gps turn it off----only if you need)

wifi---advanced--keep wi-fi on during sleep-----never

more settings---Mobile networks---network mode---->GMS only (for whatsapp,gtalk little bit surfing its enough)---then go back

NFC --S Beam--Allshare Cast---->off

Blocking Mode ON ----set time 23:00 - 05:00 in the morning (thats in my phone)

Display---multi window/Page buddy/smart rotation/Smart stay/touch key light duration---->all off----then set automatic brightness and timeout 30sec

Location services---->untick all

Security--find my mobile--remote controls---->off

Backup and reset----Back up my data---->untick

google----Ads---google AdMob Ads---->untick

Developer options---ON---window animation scale set to 0,5-------transition animation scale 0,5

about phone----software update---->untick all

also go playstore ---settings---notifications--->untick........scroll down....Google AdMobAds--->untick

with titanium backup i freezed allshare cast.....news and weather....yahoo finace...gmail(i have aquamail....and there i have disabled "check email in the background" and IMAP Push) ...chaton/flipboard/game hub/all the samsung stuff....bloatware ****

also you can install ALL-IN-ONE-TOOLBOX from the market.very great app..... you can disable app/system apps from startup (S Memo and other stuff)

and if you go to bed ;) of course AERPLANE MODE....;)

of course "Rescan Media Root" from the market

--For those who have

AudioOut_2 wakelock.-----------> solution:...;)

- Go into your phone settings -> accessibility

- Turn talkback on, select "settings" from the bottom of the page

- Switch off all the talkback checkboxes

- Then switch talkback off again

- Go back into phone settings -> application manager

- Choose the "all" tab

- Find google text to speech (tts), click on it and click "disable"

- Find samsung test to speech, click on disable

now you can try a few settings from the list....

PS:All these things you can re-enable, but only if you need...;)

cheers and greets

BUT testing...i ave the samsung galaxy s3 not a "brick". i mean for disable all the things etc hehe.

Seem that my battery after disable my usual livewallpapper run normaly, hi mean by now, because i am in the cycle of testing battery.

My battery performance...

Hi all,

during my sick break now I took the chance to NOT flash all the time and check a little bit battery performance of 2.7.1 kernel.

This is my result:

1 day and 20 hours total time, around 2 hours screen-on time, and still half of the battery left.

All I can say: I am personally very satisfied with this battery performance.

So, in theory this means, everyone should be able to reach that.

My current test config is, by the way: The three tweaks off, LED fading on, usb charge rate on 900ma, headphone volume to 60, eargasm equalizer, private mode on.

My rom: Samsung stock XXEMA2, odex, debloated, XXELLA modem.

Andi
[Galaxy S III Android Development] upss16:
why u kept 3 tweaks off?

hi, hope u r feeling better now. can u pls tell as u mentioned, why u have the 3 tweaks off. will it by any way affect the battery life?

anyway i am fully satisfied with the battery life with these 3 tweaks on(as per default)
[Galaxy S III Android Development] andip71:
Hi,

yes, thanks for asking. Much better already now.

Well, it could affect battery life. But for my test I more wanted to check how smooth stock kernel without tweaks is.

If you are happy with the tweaks on, just keep them on. It is usually what I propose (and therefore also default to it).

Very grateful AndiP. ;)

[Galaxy S III Android Development] mstevan:
Andi, just want to say, i have better result definetly with 2.6 version. Dont know why, but that is definetly. Maybe because of rom.

And also want to say, that even with battery drain with 2.7.1 version your kernel, by my personal opinion, this is the far best kernel for S3. Thx for that.

Hi Andi,

I have an high battery drain of service called "Media".

I'm on wanam 5.8 and bloeffa kernelv.2.7.1

Can you help me?

Thx in advance
[Galaxy S III Android Development] andip71:
Hi,

which rom are you on? Based on which firmware?

Reason I am asking is: There is no logical reason why 2.7.1 should need more juice than 2.6. The only, purely theoretical, thing I could imagine is the changed ram disk. And that is why I ask...

Andi
[Galaxy S III Android Development] andip71:
Hi,

hard to say. When media is is going crazy (I suspect it is the media scanner service), it is usually a sign something is not correct on your sd card anymore, or you have thousands of media files stored.

If you read the thread a bit up, there was a recommendation for an app to help you with that. I am sure you will find it... otherwise Cybdani will tell you again here. I guess :)

No evidence anywhere, or reason why it would.
[Galaxy S III Android Development] tlf55:

[Galaxy S III Android Development] LenAsh:
You wouldn't notice that either... BFQ appears to be the favourite though.

How would YOU actually know?
[Galaxy S III Android Development] mstevan:
It is a Neat Rom Lite 1.7 based on XEMMA2. Right now i dont have a screenshot of 2.7.1 kernel but here is from 2.6 (today).

With 2.7.1 that will be about 80% battery left (+/- 5%), and never had a such a good % between deepsleep and awake. Really dont know why it is different, but between stock, perseus, 2.6 and 2.7.1 - 2.6 is far, far best kernel in any way for me. Others say that they do not have that problem as I do... But like i say, il stick to your 2.6 version and this ROM (1.7) until 4.2.x arrive to our phone.

[Galaxy S III Android Development] cybdani:
This is a common problem in Android 4.1.2. Doesn't matters what rom or kernel you use. Normally is caused by corrupted files in extfat file system + buggy multimedia service. Never happens to me with FAT32 filesystem. At the moment we don't know if it is a bug in Samsung code or google code in Android system.

You have two solutions:

1-Make a backup of your ext sd card files to another location. Format sd in pc with FAT32/4k filesystem. Restore your files.

2-Use app called media scan root.

You can try if it helps.

It is easy:

If you ever created a boeffla-kernel folder on your sd card -> delete it.

Clean up your folder /system/etc/init.d from all scripts

That's it.

you can now download the latest stable version 2.7.2 (or get it directly via Boeffla-Tweaks by going on Load&Flash).

There are only some internals changed/reverted, there are

NO functional enhancements or changes
