I have a LG Optimus One and the new Facebook update has caused the news feed to constantly refresh so that it is unreadable. I am normally on WiFi, but left my house for two hours today with 3G left on. I barely used the phone, a couple texts and checked email. I noticed the phone felt hot but didn't think anything of it. When I got home I noticed I had used 48mb of data (my monthly quota is only 100mb) and my battery dropped from 70% to 20% (usually my phone is between 40-60% when plugging in at night). Checking the Phone Usage app told me that all that data usage was Facebook. Has anyone else noticed this?
