So here's my story. I use "Advance Task killer" and ONLY kill apps that I initiate such as games/pandora/etc. I also do the charging trick to calibrate the battery to prevent it from dropping 10% in ten minutes. Turned off auto-synch/background data and pair that with a Sprint Airave and my phone lasts quite a while. Took my phone off charge at 5pm yesterday, it's now almost 3 am. So ten hours (100 texts, 30 minutes of listening to music, some facebook browsing, WIFI on) and I'm at 78% still. I guess it having poor signal around my house (before airave which I got for free and I recommend to anyone) was what was killing the battery.
