So can you give us a blow by blow specifics of what you have done?
What ROM did you come from? Are you using the Stock ED01 radio, or ComRom radio? What and how did you set your voltage control settings to? What are you using on your device (phone, wifi, gps, etc.)? How strong a phone signal do you have in your area... etc.
Thanks
Okay yellowfin

So I ended up going back to stock. If you want to try it, go here: Samsung Fascinate Rooting, EB01, Return to Stock, Remove System Apps, Other How-To and follow the directions to get back to stock. Then do an OTA (over the air) update for Froyo. You'll have to do two updates for it to be current. After I was running stock froyo (ED01 radio) I flashed the KangBang Comm Rom... at the time it was v1.1. Since then I've flashed both v1.2 and v1.3. As it stands, v1.3 is the booyah for me!
I flashed the rom first, THEN wiped cache and dalvik...
I keep wifi on when it's available. I'm just in the habit now of turning off wifi when I leave anywhere. I keep GPS (google location) on all the time. I keep mobile data on only when I'm not using wifi.
I use a dark background (not a live wallpaper) and I keep it set at auto brightness.
I have decent phone signal... not stellar by any means, but decent.
My voltage controls are actually all back to 0. I didn't reset them after the last flash. Right now I'm super happy with my battery so I don't think I'm going to mess with it yet.
Before I flashed 1.3, my settings were as follows:
Limiter set at: 1000
Scheduler: sio
1000: 0
900: -50
800: -50
600: -50
400: -75
200: -75
100: -75
I may try this again, but like I said, I seem to be doing fine right now...
It's 10:30pm, I've had super heavy usage all day and I'm still at 60%. I can't believe it!
Hope this helps...
