Well, I blamed Helix, Beautiful Widgets, Weather Widget Donate, and countless other apps for severe battery drain. My phone would not sleep when in airplane mode and it was the Android System eating up all of the power (per Spare Parts). I realized that I was waiting to put the phone into airplane mode after I had already lost signal. The phone wouldn't sleep. I then found that if you put the phone into airplane mode before you lose signal, all will be good. I'm running 2.1 v2. Never had this problem before while running 1.5. Hope this will help some people who use airplane mode frequently.
