Alright so I've had my Samsung Focus for a while now and one thing I still have yet to figure out is the battery drain. It seems like even when I don't use my phone a lot the battery still drains. There are times where I'll be at 50% battery after having my phone unplugged for 5 hours, listening to an hour of music and checking Twitter a few times (over 3G).
Is there something I'm missing? If I turn 3G, WiFi and GPS off then I'll see battery life more in line with some of my friends' Android phones.
Settings wise I'm checking for email every 30 minutes, but other than that I don't think there's anything else really hitting my data usage.
