mengsuan...you on eclair right...because voodoo beta4 is for 2.1..why don't you try voodoo3 with jm8 kernel..i used it with my stock eclair and no battery eater..

but sorry i forgot the link from xda...

do you or any guys here noticed that after the phone calls, the screen will become greenish like 1-2 second when you move the phone away from your ears?
i didn't noticed this happens before.

i happened after i apply voodoo pre-4,but i m now on z4mod and its still persist.

i wonder if this is normal

I assume you didn't reboot after the lagfix?

No idea why your phone stays awake, somehow Voodoo Beta4 works for me, especially on battery saving department.

Yep, that's my experience as well. Voodoo is built off the open source kernel released by Google. Samsung has done lots of customizations on top of this kernel that improve battery life tremendously (on the Galaxy but that isn't saying much). I'm on the JM8+Voodoo4 kernel and it's been going ok so far.
As much as I'd like to believe this, SamFirmware is not Samsung official and hence, it's no more than an unsubstantiated rumour at this point. I'll believe it when I see it. The Galaxy S and all its problems (lag, GPS, mysterious power drains, half assed Froyo implementation) and Samsung's inability to acknowledge much less fix them has seriously made me think twice about owning any future Samsung products.

I kena this a number of days back. When I posted my experience and attached the z4mod.log file, RyanZA could only say, hmm, it should not do that.

Anyway, I have reflashed my phone to fresh JPM, rooted it using the 1.2 CF Root kit, and have applied the so-called optimized kernel. Testing now without any lagfix.

guys is the universal lagfix is meant to froyo only ?

guys, did u all realise that there have upgrade version fw through kies ??
stock fw

My Eclair JG4 is 325MB as shown in the Samsung's Task Manager.

Likewise.

is he sure that its the FIRMWARE upgrade, not the kies software update

The only shortfall is access to database is slow on Voodoo. 1 example is my WhatsApp. Incoming/outgoing messages will jammed my phone for 1-2 seconds.

Yeh, Voodoo on default kernel was a battery sucker for me too. But strangely, the earlier betas - Voodoo 1 and 2 - were okay despite locking the CPU at a constant 1Ghz. Could just be my imagination.

Did you try Voodoo JM8? Was there a discernible difference in terms of performance/power consumption? Reason I'm asking is that I'm on Voodoo JM8 and too darn lazy to move up to Voodoo JM9 unless there's a marked improvement.

Also, I find that games like Abduction which use the sensor will not properly disable the sensor after exiting. This is a huge power drain for me even on Voodoo JM8 as the sensor's running at 100% the whole time. I've only been able to fix this by reseting the phone. Weird.
I've identified a few battery sucking apps which I've either uninstalled or do not run at all, not sure if you guys agree:
1. WhatsApp (lagged, delayed messages, sucked power, no way to disable)
2. Trillian (this was a real battery killer - I hate it now)
3. eBuddy (was always a battery killer)
4. Tweetdeck (great app, shame about the power suckiness)
