Over the past two days, I've noticed every time I look at my phone the two arrows beneath the 3G symbol are both on constantly. If I go in to settings->about->Battery->battery use I see that android.process.acore has received over 30 MB. What the heck is it doing? My battery life was pretty good until yesterday when I began noticing this behavior. I had to put the phone on the charger after only 8 hours of use yesterday.
