The first thing I would suggest trying is to re-calibrate your battery and allow it to go through 3 or 4 charging cycles. See post #1, here.
Next, you can install BetterBatteryStats to see what is using your battery, see here.
If you are on the latest NEAT ROM, MS1, you could try changing to NEATROM LSJ which, for me, is the best release so far, after a GS2ROMNuke and clean install. See Hawker's post #1, here, entitled, "Full wipe. What's the big deal? Steps to take (15 mins)".
Depending on your location, there are not a lot of JB modems to choose from, see, "Modems - Dummies Guide".
