Consistent q scores in the 2600 range, phone running very smoothly and very fast in daily use (internet, twitter, pics, camera, messaging, phone), 130+ apps installed, no issues. Seems a much better base firmware than any of the 2.3.3 variants.

Thanks for your feedback, happy user!

I must say that 2.3.4 battery is performing better than 2.3.3 so far.
After 11 hours with gps and auto rotate on, battery still have 30% of juice left.

Comming from Froyo JPY to stock deodexed JVP, I have noticed a higher battery drain.

I lost 13% overnight, I had 21% battery use on cell standby (6hours of use). and I noticed something very strange, android system has a 18% battery use with only 5 minutes running, WTF???

I'm using stock deodexed rom from ramad, Dark core kernel and screen off animation. that's all I've changed to this rom, no games, and a few apps like titanium backup and atk.

When I tapped on the android system there was a huge list of included packages, I will list them here, maybe one of them (or all together) is causing that huge battery use:

com.samsung.InputEventApp
Service mode
Software update
Google Backup Transport (actually, I turned off google backup, idk why this is here)
Settings Storage
Mobile tracker
Account and Sync Settings
EncryptApp
Task manager
Error
Perso
com.sec.android.app.lcdtest
VPN Services
Factory Test
wssyncmlnps
PopupuiReceiver
Preconfig
BluetoothTest
Self Test Mode
WlanTest
Status Bar
Settings
Mobile tracker settings
Android System
DRM content
MTP Application
PhoneSetupWizard
Security Storage
Licence Settings
PhoneUtil

Those are all......

It seems that you have a normal consumption on Android System. Also that app list is present on every ROM which has all system apps. On lite ROMs you can get a smaller list, because some of those apps are removed by the chefs.
Maybe your network coverage is not that good
After a flash, the battery needs stabilization, until then it can drain fast. Try to recalibrate it. Please tell me if you need a good guide.
Try a lite ROM. Maybe you will experience a good Android System consumption.

Thanks for the feedback!

Look at the poll results so far 72% say they have no battery issue, so it must be the apps on your phone that are at fault for any unusual battery drain.

Look at your own apps first before you blame the rom, mostly it's not the rom that's at fault.

When you're not really using your phone, Android System will have a higher battery use percentage, because nothing else is using battery.

Long periods of idle, you will see higher Cell Stanby and Android System percentages.

The more you use the phone, those percentages will lower.

This is what i had with the previous JVO (2.3.3) and not using any task killer anymore. I moderately used the phone, made some calls, wrote some SMS, had blutooth on in the car, listening mp3. Ah, and i set display brightness to "auto" always, i don't use the manual setting with lowest brightness value anymore.

But i also can get the battery down in less than a day...

I'll give the new 2.3.4 a try.

It's funny to see that there is always somebody who needs to torture the board with reinventing the battery wheel. Strange battery behavior usually shows up (and is often dependent on them) in threads with special roms or kernels. The only thing this thread will brings us is more of the same on how to save juice if you don't want to fork for a larger/extra battery.
