recommended to do so to avoid any lags/battery problem, but remember to back up your data first though 

hmm.... sorry i am not able to help on this cause everyone needs is not the same. Someone may i know what S3 preloaded. Someone may looking for something more advance... someone may want different look and feel...

The only thing i need to say is very personel...

papago m9 works

might be charger prob, might be software prob, might be battery prob.

hope i can help on that particular prob but one thing need to advise
better dont charge only when it near depletion.. it will strain the li-ion battery heavily.. less depth of charge(DoD = 100% - remaining charge, dont know how to explain in word  ) will prolong the batt life(increase it recharge cycle)..

empty all is a no-no.. it is equal to 100% Depth of charge which according to data of battery university(link below) the li-ion cycle is only 300-500..

when u charge while ur batt shows 50% (DoD = 50), cycle increase more than 2 times (1200-1500), means reduce half of the depth, u got more than twice the benefits

lvl recommend i think hard to recommend cos it depends on many things.i charge mine around when reached 30-40%.. just to giv u the real concept rather than some myths floating aroud

i dont know how android handle calibration cos android stored a file bout battery stat in the os not the battery and google around doesnt have a consistent answer, some say this some say that so i chosen force calibration thru an app called.. battery calibration by Nema

inside the app got instruction on how to do it and its concept is like what the batt uni is..

From my understanding, this is a bug which is not resolved yet.

There is another apps in xda that you can used which has similar functionality.

I stopped using light flow as it causes battery drain, google about it you'll see many users complaining about it.

for the annoying voice I used to uninstall the Samsung TTS and Google Voice through TB..

Here you go, but you must have a rooted phone for those functions in '*'.

I am using Malaysia JB Rom. No problem so far.

No you don't need too.  Unless, you want to use other additional features.

can anyone tell me how to set up so that when my eyes are away from the phone, the screen will go off immediately? thanks

why my touch key light not light up when touch the screen. Need to touch the key itself then it will light up. Not happening when ICS. Is it like this or mine is problem one? or how i can make it light up when i touch the screen?

I am using, but no idea about your problem
else use light manager

ya is like that, but when u untick it, back to the brightness before you tick auto
