I have clean nova hd 19-35 and on Latest kernel battery drain at night is worst then it was before. Now i have about 10-15% drop, instead of 1-2% :-\ in about 8h of doing nothing wifi on 503 max CPU, ota set to 2 option

[LG Optimus 2x] austria89:
I'm using Nova HD RC17-30 atm (still waiting for the new release), besides the powersaving mode of the kernel I'm not using any extra tools, rest of the OTF settings are untouched

BB/RIL are both 823 (RIL 0823, V21b)

I attached the screenshots, as I said, light usage, so screen on just in case (a few calls, some messages, some mail checking, a few app updates and occasionally checking facebook - no playing or surfing internet in this battery cycle!)
[LG Optimus 2x] spica1234:
Yes powersave is indeed a smart kernel management for aggressive powersaving, kernel intellectualy sets powersave threholds for maxium battery life w/o affecting the performance:)

[LG Optimus 2x] Sörnäinen:
But to be honest - in terms of battery life and speed this kernel is one of the best already.
[LG Optimus 2x] spica1234:
Lol. Yes as I said earlier next kernel will be 3.0 Kernel. I need to merge every of my OTF and other function manually so it'l take time. Till then you can enjoy the goodies of last release kernel. It's already smooth and effecrtive battery life;)
[LG Optimus 2x] solarding:
Yes this kernel is really the best that i used, and thank you again for your great work!

a stupid question though: what are the persuading improvements in 3.0 or where i can find the info?
[LG Optimus 2x] gromez:
What is the proper way to uninstall this kernel?

Just flash the default one over it and delete?

Thanks :)
[LG Optimus 2x] SREEPRAJAY:
just flash any other kernel over this....it is flashed over this kernel and takes effect....thats it.

Presently you have NOVA and HARSH kernels available for ICS other than HP.

Sorry SPICA bhai....clashing with the TITAN one more time....I was typing a reply simultaneously
[LG Optimus 2x] gromez:
Thanks for your answer :)

I thought there was additionnal things to do like delete /data/app/com.invokd.hp2xotfkerneltweaker-1.apk and config and init script

Does UMS work with ur ICS Kernel?
[LG Optimus 2x] Sörnäinen:
Not for me at least. :)

Spica seems to be still experimenting with the kernel 3, but when something actually happens, I wouldn't be surprised if UMS was part of the update.

I admit I prefer MTP.
[LG Optimus 2x] hyyuga:
would like to confirm that...kernel tweaker settings reset after reboot. is there another way to set powersave mode persistent? i figure the kernel tweaker app just reads and set data from/to a cfg file
[LG Optimus 2x] SREEPRAJAY:
u need to go to data/spicacfg and change the number there by using ESfile Explorer ....for having it in every reboot.

---------- Post added at 05:45 PM ---------- Previous post was at 05:35 PM ----------

I am sorry....I made a mistake with GB Spica Kernel settings in the data/spicabootcfg file with the ICS Kernel.

I am searching the file but I have not succeeded...

if you find one, please let me know...

thanks
[LG Optimus 2x] hyyuga:
no its right there /data/spicabootcfg/powersave,

just changed and tested it.

thanks again
[LG Optimus 2x] SREEPRAJAY:
I still cant find it....i have my external SD card as the SD card....and I find a folder 'data' and it is empty

[LG Optimus 2x] supercurio:
Hi!

Someone asked me details about that.

spica1234, are you aware that increasing sampling rate to 48kHz would only reduce audio quality and reduce battery life, by introducing software up-sampling when playing music?

Also, I couldn't find anything related in the git repo to see what it was about, as to my knowledge kernel itself has nothing to do with the sampling frequency chosen during play, especially on Optimus 2x − could be wrong tho as I don't know CM specifics but still.

Note: what do you mean by hw accelerated ?
[LG Optimus 2x] spica1234:
Here the changes is in git in DAP1/2/3/4 https://github.com/spica234/HP-2X-V20Q/commit/369c0648e31b742aced2ebf3089c7bbbcf52a3ce

BB,Voice codec and BlueTooth codec shows 24000 thats old commit, its 16000.
[LG Optimus 2x] supercurio:
Thanks, did you made measurements to see what the effect is?
[LG Optimus 2x] spica1234:
Welcome, No i did no professional measurement But i feel more clear voice during voice call may be it's placebo or real:/. I released first experimental test build before this build. And ppl wanted to have this feature so i kept it in this build. Actually I'm no guru when it comes about sound. So i'd like to know from you, as this would have any impact on sound? Or should I revert it? Appereciating your suggestion:) Thanks in advance, nice talking to you. Plus i want to know from you as well that 24Bits will have any good/bad impact?
[LG Optimus 2x] supercurio:
For every modification (I mean any kind, not only sound) I recommend to take measurements before issuing a public release.

Its a methodology allowing to bring moslly improvements. Kernel changes introduce as many regressions as improvements otherwise − and its not uncommon with custom kernels.

However, for 48kHz instead of 44100 , measurements are not needed as changing the sampling rate can only reduce output quality for reasons explained earlier.

Note: without measurement there's no way to know if the patch actually does something, except if there's a dramatic change in voice clarity.

On most implementations sampling rate (and 16 or 24bit) is hardcoded at compile time in Android audio libs and AudioFlinger resample everything so it becomes the rate chosen.

That's why It seemed unlikely to me that audioflinger behavior was depending on kernel configuration, but as we know NVIDIA impelmentation in this device is very special so ^^.

Well, I'll take a look at that later for VoodooSound/Kaudio Optimus 2x driver.
[LG Optimus 2x] Ferrum Master:
I warned Spica about that but he didn't listen... :p

Although I put trough right mark sound audio, but could get any reasonable in difference. The hardware implementation without proper ground degrades everything... :D.
[LG Optimus 2x] spica1234:
Now I'll listen this is old build bro, it was released before you said. But i must say sorry i should have lsitened earlier;)
[LG Optimus 2x] Sörnäinen:
It is a community build, isn't it? I wouldnt expect you to take measurements, trial and error is quite fine if there is enough feedback and it's used in the end.
[LG Optimus 2x] spica1234:
Ok, thank you. It's indeed very useful. So i'll revert to 44.1 and 16 bit for now. I also need suggestion about DAP2/3/4 code modification, Does it also need to be reverted alike hificodec DAP1?

And we're desperately waiting for your new voodoo driver. BTW I used my bro's Galaxy S for a while. When in ICS i changes RGB values of your modification in settings menu in ICS i mean in minus(-) values it makes more vivid color appearence.
[LG Optimus 2x] supercurio:
44100 Yes.

revert to 16 bit instead of 24 bit: cannot say without measurements.

If it actually does something, 24bit uses more power as the codec and i2c bus will be clocked higher to deal with the additional data, which is not necessarily useful as most media played are 16bit anyway.

About DAP2/3/4: the easiest recommendation I have is to use current Voodoo Sound driver as i2c command dumper and see if the i2c commands sent by nvrm_daemon change depending on the config you set.

If i2c commands are the same it means it has strictly no effect. This testing methodology might be easier for you if you're not comfortable with measuring audio signals.

About higher rates, same thing: it consumes more power. If the signal are compressed later and maybe down-sampled for voice compression, the only effect will be to reduce battery life during calls.

About Voodoo Sound for Optimus 2x yes finding solutions and writing implementations takes an unreasonable amount of time just for one very non-standard device, but eh I'm making good progresses.
[LG Optimus 2x] spica1234:
Thanks a lot:) Very helpful.

UMS support

Hi Spica,

Would you implement the UMS support on this kernel? I am using it with owain94 Kang and got problem with USB connection.

Thanks for an answer

Solarding
[LG Optimus 2x] spica1234:
New kernel will be based on kernel 3.0. Soon after i release my stock kernel. Have a great time till then;)
[LG Optimus 2x] solarding:
hmmm.... what a pity, coz i love this kernel, the smoothest and long live version.

BUT, i'm looking forward to your 3.0 version as well.
[LG Optimus 2x] slebit:
Looking forward!
[LG Optimus 2x] spica1234:
If still ppl want to have 2.6.32 kernel then i will maintain 2.6.32 kernels as well with new releases:)
[LG Optimus 2x] crazy_dj:
personally I found the 3.0.y kernels not as fluid as yours , but it might be because your kernel is the most optimized.. but I am sure that most of the users will try your version of the 3.0.y kernel :D
[LG Optimus 2x] 75markus:
harsh kernel 2504 is the best 3.x kernel for me at the moment, quite fluid and battery friendly...

i´m excited what your build will be ...:)

will you build it from the scratch or take harsh as a base ??

if you manage to include all your tweaks, it will be a killer !:D
[LG Optimus 2x] slebit:
Same here. Harsh kernel is working great for me.

But with spicas tweaks his kernel will be awesome. :)
[LG Optimus 2x] eepuri:
what is not working in this rom

HI,

Before I could install this rom I would like to know what is not working with this rom.

eg: Hardware acceleration like video recording etc. Please specify.

I think that would be of great help to anyone who intend to install. Rather they post back what is not working for them.

Thanks!
[LG Optimus 2x] Sörnäinen:
Be aware this is not a ROM, it's a kernel only.

You might want to do somw further research on the differences. ;)
[LG Optimus 2x] solarding:
honestly i don't care if it is 3.0 or 2.6.32, as long as it works stable and smooth. As a normal user with a bit flashholic, kernel is very important, but does not need to be very new, rather stability and bugfix than new features.

The problem always bugs me is the signal lost problem. I got the problem with all the CM roms although i ensure wiped cleanly before isntallation and 725BB+RIL. It just happens randomly, or maybe ofter while entering or leaving WIFI covered area.

Should it be on the earth Kernel or ROM problem? or BB and RIL?

I sought many forums for this, recently noticed some fix for multi-radio error or something from CM7 commits, and also some fix from google for similar problem for Nexus,,,,but no one here seem to give a notice on it, seems like nobody else having this problem?

PS: I use Nova RC24-50 + the latest HP Kernel,,, sofar the best i think. would make a backup as milestone :D
[LG Optimus 2x] spica1234:
Thank you guys for still using it.

I will release my kernel for stock rom today/tomorrow then i will start progressing faster on 3.x kernel for ICS. But before that,

Meanwhile i will release a maintance update of HP RC2 ICS KERNEL based on 2.6.32.x kernel:)
[LG Optimus 2x] tablerone:
I had this problem with all the BB that I tried, also with CM7 or MIUI. I solved installing Toggle 2G App.
[LG Optimus 2x] spica1234:
Thank you for helping, i came to know about something. To be very frank, I am not fully aware of CM usual issues as I'm new to CM:)
[LG Optimus 2x] tablerone:
Thanks you for this great kernel.

I'm anxious for try the next release :)
[LG Optimus 2x] solarding:
oh,,so were busy with tweaking stock rom and kernel? I flashed my phone with CM right after i got it, and never used the stock rom ever since. thats why i decided this phone :D

so is it a stand alone app from market downloadable? i ask coz CM has this toggle function natively. So u use 2G all the time.?

Actually with latest build from owain things get better,,,so although no one answered, i suppose this is related to the rom not the kernel
[LG Optimus 2x] 75markus:
+1, i also think signal drops are much better (nearly gone) on latest kang :)
[LG Optimus 2x] tablerone:
I thought that he was talking about the lost of date conection when swicht off the wifi. I had this issue from a long time and with this app it's resolved.

The app toggle to 2G when you aren't using the phone or when you connect to a wifi. You can configure a lot of decision parameters. Also it resolves my problem :)

I keep flashing back to RC30 on Nova with this kernel. Its the only combination that seems to work well for me. This kernel has great battery on power save 2. Can't wait for update. Anyone have good battery on RC58. Mine lasts a matter of hours?
[LG Optimus 2x] brownstein:
This kernel is the best for me. Whenever I flash the latest build of Owain, I wait before installing this kernel and test a bit the Harsh kernel and definitely this is what gives me a longer battery life and smoothness. Have also tried the SuperNova and the final result is the same, this one is still the best by far.

I'm on build 61 of Owain at the moment and looking forward to the new release! :D

I had this problem also.

After kernel instalation phone reboots BUT on this applications refresh/checking it gave me an error and i rebootet. After new reboot everything was gone. Only fresh tom was installed.

So i decieded to make an new instalation and restore my applications.

right now im not using your rom coz im affraid that i will again loose all ;)

Check your USB connection method... this kernel does not support UMS method, so you must choose MTP.
