I own a Dell Streak running Android 2.2. I ran a basic monitoring tool that showed that if I left my phone in idle for a month, it would consume 130mb. I prefer not to disable background data so I can get email without going into it. The only apps that run in the background that I'm aware of is email, weather, and I think the Dell Stage UI. For the other apps, I've set them to update every 4 hours or so. I have also checked to see if there are any applications that can monitor usage by application, but I keep finding the ones out there do not work due to the way the Dell Streak has implemented Android. Please help!
