The other night I went to sleep with 60% left on my phone. I woke up and my phone was at 29%. I checked spare parts and it showed facebook using up the battery. I have the facebook app installed and signed in. I also have facebook for htc installed so my contacts show up. The account syncs once a day. Since that day, I've signed out of the facebook app but I still see that its using up more battery life than android system per spare parts. But I haven't noticed any huge battery drain. Anyone have any ideas why facebook is still showing up as draining the battery? Thanks in advance.
