[Q] Slow screen refresh kernel

I want to try a kernel compatible with CM9 on my i9020 with a slow refresh rate to test how many battery can be saved.
I see in bedalus kernel comparison that AniDroid Hardened is a 45fps one but seem a little out of date.
Any other kernel with 45-50fps refresh?

That's funny. I was trying to get Anidroid 45fps to work with some of the new IMM76I ROMs this morning, but had no luck.
The best battery saving kernel is still matr1x, even with nominal voltages and 56fps.

I`ll take a test with the Matrix kernel.
Have you ever compared battery drain of two version of the same kernel with the only difference of display refresh?
I`m very curious to understand how much this parameter can be helpful in a battery saving setup

Yes, as you can see in the post above, and i recently tested 56 and 50 hz versions of trinity.
It definitely affects power!

Yes, I've just readed it on the battery drain thread. I have definitely to try this.

[help]overclocking

what's the best setting for overclocking to 1400mhz without having reboot.

Raise voltages until it's stable. In rare cases, you may need to lower them. If none of this works, the SoC in your phone is too imperfect to clock that high (it wasn't intended to anyway).

Thanks for sharing those infos...
May i ask for some more?:
System details [rom, kernel]
What app is the one you use on this screenshot?
what theme do you use?
Battery life with this OC?
Thanks a lot

1. rom : http://forum.xda-developers.com/showthread.php?t=1399035
kernel : http://forum.xda-developers.com/showthread.php?t=1036996
2 hold volumen down button + power button for 2 secound in same time..
3. http://forum.xda-developers.com/showthread.php?t=1531222
4. i think it same as 1000 mhz "OC" , because i have same voltages for 1000 and 1320 mhz..

i meant what application are you using to set the voltages... sorry i wrote the question the wrong way

Quadrant Benchmark I/ O only 989

Hi Community ,
i have the tf300t tablet at home with the last FW from Asus.
The device is rooted. But when i make a benchmark test with quadrant i have only 989 by I/O .
End result is 3270 : CPU:10294 Mem: 2569 I/O:989 2D : 253 3D :2245
My opinion is taht the results for I/O and 2D is too small. Can i fix it by anyway ????
Thanks Man and sorry for the bad english !
And i want to say that iam very happy that surdupetru is also in this community. Before my asus i had a archos gen 9 and he makes the best roms for this device. And my last question to surdu will you make a rom for the asus in aokp style. Thanks !!

The I/O is a common problem with this tablet, the prime and the infinity

I get over +8000 to i/o points.

What's your PCMARK score...true battery/performance benchmark

Since I see so much Ignorant in the Battery thread, I like to point out (rant) some things..
1. A person 6 hour of Screen On Time usage is different from person to person.
2. Temperature can have a great affect on battery life.
3. Signal strength can have a great affect on battery life.
So with that in mind, I suggest everyone try to do a PC Mark bench, it is fair and give people a much better idea of what of what they should be getting. To do this test here are the few settings you need to set
1. BRIGHTNESS AT 23-25% (EYEBALL IT)
2. Wifi on
3. do not disable Mobile data or sync
4. Clear all RAM before start
below are the CONTROL numbers from a stock rom (pictures are from greenbot.com)

I've try using greenify and it sure extend the battery life a little bit but it doesn't stop the cpu usage that is always more than 60 persen (74 persen average cufrently).
I will try titanium backup

it dosent go back down to 307 mhz? somthing maybe wrong with the cpu setting. try kernel auditor app and use different governor settings
