1) Sorry, this might be a dumb question, but what does Partial Wake mean? 2) I never log out of the facebook app. Does this drain a significant amount of battery? 3) i synced my contacts with facebook so everyone in my contacts would have their fb pic as the contact pic. Things went well and the pics are generally good except for one instance. The picture of the person that appears on the screen when calling them or receiving a call from them is not clear like in the contacts section and very blurry. Why is this and is there a way to fix this? Thanks for the help.
