For a start, this is some info i thought i'd share, its not a complaint to ask how i can do better and it sure as hell not a "mines better than yours" either. just my testing info.
Current stats: NOT rooted (stock), firm- KG4, 2.3.3, only real changes are GO launcher theme, 3g watchdog,few games and odd apps but no "battery saving" apps or anything like that.
I started with a dud battery with my brand new phone, got about 15hrs at best no matter what i was doing. took it to samsung where they tested, confirmed it was a dud and gave me another one.
now being paranoid of getting another dud one, i tested this new one by leaving off any running apps, turning off wifi and data and leaving it for as long as possible. I also have some spare ebay chargers i bought cheap which i had some questions about there "reliability" you could say.
So, below are some results, i love doing my little tests here and there to see what it really going on. to know ones phone means to know ones problems that arise. i try to do the same with everything, know your car/pc/etc..., know how to fix it.
(except the missus, can work her out, sure as hell can FIX her either!
)
1) having at least wifi OR data usage on with 4 accounts auto syncing i get 1 day, maybe a little more, maybe a little less. that was my starting point, what am i doing to make it better and whats making it worse.
2) So, turned everything off, leave it over night =

3)*lastest pic. done this morning =

4)so, happy the new battery isnt a dud one. time to see some facts.
charged up full with the ebay charger. the wife speculated hers died faster from the "faster charger", my test confirmed it left everything off and left it alone = FAIL CHARGER

5)after charging it back up with the stock charger, i left the data on. Now i'd like to point out i live at the edge of the 3g connection area. im kinda outside the "metro" area, hence, it continually searches for the better connection, swapping back and forth. the weak signal swapping around i think would suck the juice more if i lived in a solid and stable area. unless i move i cant really test that yet =


6) now this made me think, maybe the other charger has "corrupted" the battery. so i drained it till it died and charged with the stock one. unfortunately results were similar.
i dont intend to use the ebay one much. its more of a "left in the car/at work in-case of" thing. if i have a heavy day and need some juice ill use it.
7) so now i leave off the data and wifi and just use it like a phone. take and make calls and messages, try to stay away from angry birds etc (lol) FYI - game DO kill it, dont need to see screenies of that.....
results of using it "like a normal phone" =

8) i try to leave on a dark kinda wallpaper, dont do many widgets really, i look out a window to see the weather lol, =

SO, at the moment, if i want to do something online i turn on wifi or data (depending if at home or work) other wise ill leave it off. if im not near a pc (which i use at home and work) then ill put data on for a bit and let it sync or just do a manual sync every now and then. i dont use that ebay charger where possible, and its easier now 3 other guys have the same phone at work, some one has a charger floating around most of the time if needed....and now i am hassling vodafail to give me a new firmware to test. in the short run i'll probably just do a manual one via odin as i think they are gunna ban me there soon. the support community is useless, they dont know anything about there own updates or even what software they have released. no help what-so-ever.
So that is sums it up. i plan on doing some more tests, ill post any results which i find make a difference, unfortunately ill have to wait for an update for any real major changes.
hope this helps those who are questioning "whats yours like".
If your in doubt and have crap battery life,
1)TAKE IT TO SAMSUNG AND GET IT TESTED.
2) know YOUR phone, do some tests yourself. it will also help if you have to take it back, you can show and tell them EXACTLY the problem.
that's another reason that started this for me. i wanted to build a case file if i required a replacement.
In the end, if i can leave everything on and it lasts me the day, im happy. its a kick arse-battery draining screen that goes faster than my home pc and ill have that over a phone that lasts a week and looks like a small crappy alarm clock.
