Eh -

Confirmed, although I only noticed it on the lock screen. I shrugged it off as minor until I actually couldn't unlock it for awhile :(

I have never had even one issue with Eugene's kernel before this...and I flashed

every single one!

I'm assuming my Samoled is just sensitive to UV... and my solution was to roll back to Speedy-6

Thanks Eugene for kernels that KiKaZZ! :)
[Nexus S Android Development] gellow:
I've been using the latest Speedy kernels with Codename Droid ROM and I'm very happy with this combo.

However, I feel that I could get more out of my phone with the right governour tweaks etc. so it would be really nice if someone could share his preferences. I'm looking for a good battery life, performance can be somewhat weaker if necessary.

[Nexus S Android Development] owenjm:
Just wondering what rom you're using (or what other tweaks you're using) to get that battery life? I'm using bigxie's Apex rom with Speedy 7 and not getting even half the screen-on time you're showing with web browsing as my main activity .... (am lucky to get 2.5 hours currently, when I'd normally expect 4-5 hours like what you're getting)
[Nexus S Android Development] aLNG:
I will pm u my settings because I'm still testing and testing to get at least 5-6 hours screen on time
[Nexus S Android Development] AeroEchelon:
Agreed! I'm lucky to get about 2.5 hours of on screen time as well. (CodeName: Android + Speedy Kernels)

Going to try out PA's Bugless Beast + Eugene's kernels to see if my battery life increases under the same usage!

It would be great to see your setup.
[Nexus S Android Development] lolokman:
5-6 hours:eek:

I will be happy if I can get 4 hours screen on time.

But what I can get is just around 2.5 to 3 hours:o
[Nexus S Android Development] aLNG:
u should know that battery life depends on many things

- how u use ur phone (wifi always on?, data always on?, etc..)

- apps u use (certain bad apps drain battery faster)

- display (i9023 use white background, i9020 use black instead)

- ...

u can read here for more info

im just undervolting arm voltage and int voltage but still maintain the smoothness. i dont use 3g. and right now im testing which gov setting is best with this voltages.

u can try his setting. he is using matrix kernel which by default already under-voltage. if u are using ICUP u have to find out urself which voltage stable enough for u with performance u want. i can tell u my voltage setting if u want.
[Nexus S Android Development] :
The biggest gains are to be had by reducing your screen brightness.

For kernel benchmarks and more, see here: my thread
[Nexus S Android Development] Kramonte:
aLing

you wrote on a i9023 its better to use with a white screen, but isn't it better to use a dark screen?

for example on my TV (Plasma) it uses more energy when showing bright scenes or films.

Thank you
[Nexus S Android Development] aLNG:
i9023 use slcd better with white colour

i9020 use samoled better with black colour.

Idk ur TV used which technology

But u can Google it to find out
[Nexus S Android Development] Kramonte:
i wrote its a plasma, so i guess its similar to amoled displays.

I don't remember clearly, but somewhere i read that any display, doesn't matter if lcd or plasma or oled, the brighter the display the more energy is used. ill research it.

thanks anyways

back to topic :)
[Nexus S Android Development] OCedHrt:
Just wanted to confirm that I didn't just reinstall speedy 6 :)
[Nexus S Android Development] GerManiac:
USB OTG?

Is USB Host implemented?
[Nexus S Android Development] melvinchng:
Slcd should be average on every colour. Led save energy on dark colour.
[Nexus S Android Development] ataranea:
This is beginning to worry me a little.

I'm on the newest kernel, used the dalvik wiper to clean before installing.

Situation is this : Fully Charged at 4am, by 1130am it was at 67 percent. And by 2pm it is at 39 percent. I have not touched the phone much cept for the few texts.

Governor is lulzactivev2 IO: SIO. Everything is default settings. I am not sure on why the battery is draining so fast.
[Nexus S Android Development] bioan:
You definitely have a background app that causes this. I always get over 30h with this kernel.
[Nexus S Android Development] ataranea:
Not sure what app is causing this. I usually only run Spotify, facebook, twitter. Anyone have any clues, or how I can go about in trying to find it??
[Nexus S Android Development] adamus123:
not sure... but your screen was on for the first 2.5 hours!
[Nexus S Android Development] ataranea:
That's weird...I am at a lost.
[Nexus S Android Development] uansari1:
Eugene.. Couple things. First, nice avatar. Second, great work on the kernel.. It's hands down the best performance I've experienced on this device. Is there any chance you would consider implementing the "cool colors", an alternative to Voodoo, as Steve Garon has done in his kernel?
[Nexus S Android Development] spitzedanese:
What about Google+? When I signed out of Google+ I got a lot better battery time.
[Nexus S Android Development] keb00:
Amazing battery life, and nice performance for a normal use! And no lag in animation of menu to homescreen...

Full recommended! :D

[Nexus S Android Development] gamin92:
This is only for amoled screens, i9023 is slcd, so no voodoo color for i9023, which doesn't need it.
[Nexus S Android Development] reapsor:
Nice thank you, can you confirm that it works?
[Nexus S Android Development] mattkroeder:
thanks to eugene373 for your work

this kernel and AOSP+ rom makes for a very nice ICS experience. I don't really do any benchmarking on my Nexus but I must say that this kernel + rom combo feels as reponsive as GB did.
[Nexus S Android Development] AndroidUser00110001:
I love this kernel on AOSP+ ROM and was wondering if it is ok with eugene to use it as the default kernel for the ROM :)

---------- Post added at 11:17 AM ---------- Previous post was at 11:12 AM ----------

I had the same problem and asked eugene373 for the config. I don't recall where it was, check back a few pages. If you get the kernel compiled may you please send me a message. Would like to compile this kernel too...
[Nexus S Android Development] aLNG:
you are right..
[Nexus S Android Development] nexusphone:
Yeah :) init.d needs busybox, you can install that in market (free)

Most custom roms already have busybox, but stock and Peter Alfonso not
[Nexus S Android Development] eugene373:
A. You shouldn't have to register at the website to download the link, if you do I'll have a talk with the form owner..

B. Voodoo Control app works with my i9020T for color & sound..

C. Deep Idle is not the same.. I've used my own parts for it, so NSTools will not report correctly. Use CPUSPY for checking please.

D. I Use SmartassV2

~Eugene
[Nexus S Android Development] 93ae8074:
Hi Eugene,

Thanks for your work in advance, may you tell us how to check in CPUSpy for Deep-Idle? Is my understanding that CPUSpy only reports Deep Sleep.

Cheers.
[Nexus S Android Development] eugene373:
if deep sleep is working, then deep idle is working.

if deep sleep isn't working, then deep idle isn't working.
[Nexus S Android Development] AnthonyAldrete:
any idea why voodoo controls dont stick when reboot ?
[Nexus S Android Development] m1k3yG:

[Nexus S Android Development] renna1992:
eugene quick question: deep idle should work regardless which cpu governer we are using, right?
[Nexus S Android Development] stevencpoynter:
This is such a sick kernel, it should be since I understand it took 102 different builds to get it running right? Question, how long until other devs patch their kernels to 3.1.5?

You had what i use to call "blackout". Blackout is when the system hangs some process and battery is unable to supply it properly, then system goes down for not enough power on a instance. Next time system boots, you see your battery drained.
[Nexus S Android Development] kevincwelch:
Excellent idle

This may not look impressive for a first glance, but I've NEVER had this degree of idle without putting the phone into airplane mode.

Bigixe/3.1.10

noop, Wheatley, 210/840 (OC 105%)

Simply awesome.
[Nexus S Android Development] kevincwelch:
BTW

Not so sure....
[Nexus S Android Development] ataranea:
So how can i fix this?
[Nexus S Android Development] nickmv:
This is unusable for me.

Wiped cache and dalvik, then flashed Speedy-7, and it hangs on optimizing applications every time. It'll hang on a certain app (unknown), then the phone reboots, and a blue progress bar is below the Google logo, then it goes thru boot animation again, then optimizes less and less apps, but still obviously crashing on said unknown app.

Any ideas here? Using CyberGR mod v5.
[Nexus S Android Development] uansari1:
Something is messed up in YOUR phone, not the kernel. Find that app and remove it..or just start from a full wipe.
[Nexus S Android Development] ragnarokx:
I'm on the same ROM with the same kernel. Try wiping cache and dalvik, flash the ROM again, then flash the kernel.
[Nexus S Android Development] cpaixao:
Are you OCked? If yes you can try to drop down the clock. Anyway, thats something we'll have to wait Eugene fix for us, but note that Eugene said already that "dont consider OC issues as something to fix".

@Eugene, i think you have to reconsider that, because thats not only a OC issue, since kernel is the one behind energy supply management, thats is a kernel issue too.
[Nexus S Android Development] aLNG:
if this is kernel issue, then we will have many report about that. but i just saw only 1 person got that problem. my suggestion is try to reinstall ur rom again. never had that problem since i start using eugene kernel.
[Nexus S Android Development] cpaixao:
I had advised Eugene by PM about that and its not a rom issue, I am using stock. Blackouts may happen even without you notice, when idle. System halts and boots right away, even when your phone its on your pocket and you'll not noticed that, except if your check your recent app on ram or something else like that. Your battery graphic stats will shows the green line cracked and a vacuum. You may had it and you just dont notice. look:
[Nexus S Android Development] aLNG:
the thing is i checked my phone every hour/minutes using cpuspy. im doing some testing (UV and gov test) for about a week.
[Nexus S Android Development] Po0yAn:
installed speedy-7 over steve garon's best color kernel on AOSP+ v1.2 ROM and fell into boot loops. tried w/ & w/o wiping cache and dalvik cache.

any suggestions??
[Nexus S Android Development] mamba720027:
Had this same problem coming from Steve garon kernel with diff rom. I had to do a fullwipe before speedy7 worked.
[Nexus S Android Development] stewarta:
Perhaps the clearest, and certainly the most sure-fire way is to follow the install steps in the sticky in the forum for the ROM I am running with this kernel. Guaranteed success. You must reboot before adding any apps though. I happen to like the ROM, but that is another story.

See http://xdaforums.com/showthread.php?t=1463437&goto=newpost
[Nexus S Android Development] y3mita:
You can't flash over other kernels with none of them.... You're better off to wipe system > wipe cache > wipe dalvik cache >

Then...

Install ROM > Install gapps *if needed* > Install kernel

Reboot!

NOTE: If you are planning on trying a new ROM different from one you already use, then an extra step is needed when wiping

Add > wipe data OR factory reset which is the same!
[Nexus S Android Development] GerManiac:
What ROM?

Edit: should have checked the link first... Nice... Check Post 5 on that thread, there you will find a nice dalvik-wiper from brainmaster... Good when you want to change your kernel...

on post 5 on that thread you will also find a ROM-wiper for a nice clean install... :)

Have fun...

Sent from phone
[Nexus S Android Development] mamba720027:
Yea factory reset is the way to go an thats what i did, everything working smooth now.:cool:
[Nexus S Android Development] dekaru01:
1. Wipe cache &dalvik (dalvik preferably using dalvik-wiper.zip just to make sure)

2. Install SimpleKernel 1.11 (because that has the proper scripts that will wipe all traces of your previous kernel)

3. Boot (this is very important, don't skip)

4. Repeat step 1

5. Flash Speedy 7

6. Boot.

Works for me every time. Stop saying "do a full wipe" for every minor issue or people will stop flashing altogether. Not everyone wants to start fresh twice a day.

PS: don't ever try flashing a kernel without wiping dalvik cache first. You can also wipe cache just to err on the side of caution. I do step 1 above every time I flash a kernel.
[Nexus S Android Development] cpaixao:
Hey Eugene, did you messed with the video drivers or screen orientation? If i remember well default ICS doesnt allow landscape mode for workspaces, but it is working on speedy-7. The problem is that its may be causing a wrong interpretation by some app as Asphalt 6, when you try to use sensor as steering, the screens rotates and goes to normal mode... so confused....
[Nexus S Android Development] y3mita:
FULL WIPE? only needed when changing ROMs... not kernel

I have a question for you... Why would you wipe caches manually and then use a script to install a different kernel that is going to be overridden by late kernel? I just do not get it.

Something to consider there are kernels that will install /etc/init.d with some presets and when you just wipe caches to replace a kernel then the later kernel to be flashed in your phone may have the same scripts or NOT .... therefore the next time you over flash a kernel on top of other... YOU're definitely looking for issues on your phone.
[Nexus S Android Development] Po0yAn:
well that's something I do almost every day since I got NS last year. Most of the times it works and sometimes with some kernels it doesn't.I just installed Steve garon's kernel on speedy7,and then matr1x and glados and back to sg kernel again,which by the way has the best color production for super amoled panels IMO.

I rarely wipe anything other than cache and dalvik cache. I knew reinstalling the rom would solve the problem, but I was just looking for a faster solution and thanks to dekaru he suggested me one. I'll try it next time.

neXus S i9020T - AOSP+ - SG Kernel - 100/1320 MHz
[Nexus S Android Development] y3mita:
Good whatever you think works for you!

But when considering time? what is one extra minute?

What I do when flashing a new kernel... I go to recovery TWRP wipe system, wipe cache then dalvik cache all three takes about half a minute if not less.

Then I proceed to re-flash ROM I use > gapps *if necessary* > new kernel .... all these takes about one minute

Power off phone.... wait about a minute and reboot!

Done! Everything is fresh and this is the only way I can be sure of testing a new kernel knowing I can't blame myself or others!
[Nexus S Android Development] mamba720027:
I normally be takeing a **** when I'm installing a new kernel,it helps cause I stay longer in the toilet but if phone stucks I be like oh cruddd!! and then I scramble for paper to wipe my ass. Can become frustrating install from fresh all over again but all in the kernel testing business lolz

possibly u have 100hz as min freq, if that the case try to put 200hz as min freq
[Nexus S Android Development] cahir_cz:
Yes, 100mhz min, 1ghz max, smartassv2. Will try

EDIT:// changed min frequency to 200mhz, problem solved. And since i have the same voltage for 100 and 200, i dont really give a damn. thank you

[Nexus S Android Development] _yaz_:
sure it's not the min freq. music worx fine w/smartassv2 at 100mhz for me. the only "lagginess" i experienced was when soundfx was conflicting w/voodoo because of a careless install. make a clean install as y3mita suggests above.

[Nexus S Android Development] AeroEchelon:
I always had bootloops when flashing ANY kernel over Steve Garon's kernel.

Another member recommended deleting the file:

/system/etc/init.d/98tweak

And no more bootloops occured.

No fullwipes required.
[Nexus S Android Development] asphantix:
you mean musicfx? and see this is what I don't get. musicfx seems to be a 3rdparty app in the market - why would google preinstall it? I didn't install it and it's running in the background and I wonder if I coul just deinstall it with titanium because I'm using voodoo sound with voodoo control and dsp manager as equalizer.
[Nexus S Android Development] eugene373:
I'll have a look at this, just got my internet hooked up today :)
[Nexus S Android Development] cpaixao:

I believe there specifically is a problem with Asphalt 6 on Android 4.0 (there have been many reports of the accelerometer not working properly on 4.0+). Has this game ever worked properly for you in ICS?
[Nexus S Android Development] rickbosch:
I've never wiped the dalvik manually before flashing a kernel. (This is why. http://forum.oxygen.im/viewtopic.php?id=1325)

I do however always clear the init.d folder of kernel scripts and it's never let me down.

[Nexus S Android Development] rickbosch:
Don't have a zip, I just use root explorer and delete the scripts manually.
[Nexus S Android Development] cpaixao:
I wipe all possible branches, including Davilk ones and it never let me down. However, for me, services scripts that init.d directory contains doesnt affect new kernel behavior after flashing at all. At time, cached dex files are timing bombs at wrong hands (new kernel).
[Nexus S Android Development] owenmurr:
Could anyone explain some of these new governors?

There seems to be alot with very little description on some of the lesser known ones.

sorry, i meant musicfx, really. u'r right, it's third party but it's there. u can remove it safely (i tried, no sound problem). however, it's switched off by def so it doesn't hurt if u don't. and if it's clean installed it works smoothly w/voodoo.

Guys, I have a strange problem that started a few days after I flash this kernel. When I plug my device on usb, I am not prompted to mount it. I tried to mount by the recovery, but it is not working too. Using stock rom.

Any ideas?
[Nexus S Android Development] cpaixao:
Check your usb connector (phone's internal, those golden tooth). It may have been failing for umidity or water, causing a bit oxidation.
