wanted to tell u earlier, any freq below 368mhz is also using same VDD=900. so, even if your lowest freq = 122mhz, still using same voltage, no difference in battery life.

also, if u set your max to 1ghz, in theory, should save some battery, which VDD=1200 compare stock 1.4ghz (1275), but in real life, there is possibility App run slower, everything need more time to execute, say, loading an App takes 2 ms, now takes 2.1ms, not noticeable for human, but in long run, CPU running at 1ghz longer. whereas if at 1.4ghz, it takes 2 ms, finished, it automatically switch back to low freq.

but these stuff are very hard to justify. so, u try with various setting, chose something which you think best for interaction / battery.

Amazing battery life

My new ROM is up. Codename: Cow in Black. Available in both OC and non-OC.

- 360MB ram
- New CPU governors - OnDemandX, SmartAssV2, MinMax
- zRAM
- All Black theme

If you are upgrading from any of my previous ROM, just use CWM to install it, no need clear anything. Keep all your settings and App.

If you are installing it from stock ROM or other custom ROM, recommended to do this before installing:

1. Format both Internal and External SD card (my ROM swap internal / external sd, if u dont format, could cause problem)
2. Use CWM to clear all cache, wipe system, etc

After installing my ROM:
- Do not restore anything app from Titanium or anything. Install all app fresh.

Enjoy more RAM, more Speed!

cannot tell what's wrong... possible to record your logcat and PM to me?

1) connect phone to computer
2) adb logcat > log.txt
3) run FB let it FC
4) in notebook task manager, kill all adb.
5) zip log.txt and PM to me.

LOL. she is right. you wait for SGS 3 ba!

4. Put the zip (1 file only) into Internal SD. If you downloaded the file in parts, you need to extract it (using 7zip) into only 1 zip.

Detailed steps:

1. right click on GT-I8150_COW_IN_BLACK.7z.001 chose extract (using 7zip).
2. u will get GT-I8150_COW_IN_BLACK.zip

Can?

sure can! good to know the gps.conf help u lock GPS faster. it does help me too.

actually this trick about GPS was an idea from tch9 (in this forum).

simply copy the /system/etc/gps.conf into you phone. you can download the gps.conf for malaysia in this link:

http://forum.xda-developers.com/showthread.php?t=1233359

(thanks to tch9)

Short answer, yes. Do this:

*Make sure you already has Go Keyboard installed.*

adb shell
pm disable com.diotek.ime.diopencn.dx.b2b.ancora
pm disable com.sec.android.inputmethod.axt9

Long answer, this happen because you Clear Memory in Task Manager, or using some Memory management tool. If you set to GO Keyboard, and reboot, you will still using Go Keyboard. But if the keyboard is forcefully closed (Clear memory in Task Manager, etc), the Server Manager will detect this, and thought there is something wrong with the keyboard. It will automatically chose the last known good keyboard; which most of the case samsung keyboard.

So, as long as you dont use Clear Memory, or dont kill your Go keyboard, it won't go away.

Using Cow In Black non-oc or OC?

Added on February 14, 2012, 3:17 pmOC version will give you more battery. This is because by default it is using 1.4ghz, which has underclocking voltage.

But if you change your max freq to 1.8ghz, it will drain more battery.

Yes, connect phone to pc.

Alternatively, you can use Terminal emulator. But must "su" first.

su
pm ....

Thanks for testing my ROM!

Added on February 14, 2012, 3:31 pmYes, just make sure you dont clear / format anything in CWM, simply install the zip.

if u using 4th ROM, simply install the zip. no need to wipe anything. all contact, msg, songs should be there.

however, before installing anything, i still recommend you to do a nandroid first.

hmm.. just in case, you still should do a "backup" first.

ok, need to disable Swype too:

Added on February 14, 2012, 4:15 pmif u not using Stock ROM, you can just install the theme:

without changing anything else

1. Ya, semi transparent. I didn't do it. The theme is from my talented friends: Mohd Fazrin Daud and Ilyana Isa

2. The RAM was expanded by:
- Recompile the kernel using latest GCC 4.6.1 compiler with option to remove debugging symbols, etc.
- Reduce the buffer allocated for Video / Audio recording. Stock ROM allocated X memory for this. I reduce it and test, recording still working, even on 720p. If you recording still work, nothing to worry about.

3. Most FC is due to:
- Restoring old app after flashing.
- Incomplete flashing

So, dont restore app / sms. If still got problem, use CWM and flash it again.

I tested all the ROM I release. Obviously, I wont release them if even myself got FC...

stock rom, best do this:

"7. If you are installing from stock or from other custom ROM, best to wipe everything using CWM, including your USB and external sd card. Reinstall everything from fresh, don't restore anything from Titanium Backup or anything."

Good luck! If no Force Close, it should be ok.

yes, the OC version will save more battery since it is undervolting at 1.4ghz. but not everyone can run it.
