Has anyone noticed that battery life is significantly less under 2.1 than 2.0.2? I am seeing rapid drops in my battery. For example, I routinely leave my iPhone unplugged overnight. With 2.0.2, my battery meter was at 100% the next morning despite it fetching email every 15 minutes. Now, I have probably around 10-15% drain. Furthermore, as soon as I start using the device to browse the web, my battery life drops precipitously. Between the time I leave my house and get to work, my battery has dropped to 60% or less. I primarily read my newsfeeds during the 30 minute ride, so it's not like I'm supertaxing the thing. The only caveat I'll add is that I'm using an external bluetooth dongle powered by the iPhone to transmit to my bluetooth headphones. But I was doing that with 2.0.2 and it didn't affect battery life this much. Anyone else noticing really fast drain?
