Battery Drain and Lag Not sure what happened  but the last update has made this unusable. My S4 was experiencing seriously bad lag. FB and Contacts kept freezing and had to force close all the time. Battery life went down to about 4 hours off a fresh charge. I did a factory reset not knowing the problem and it didn't help. I finally traced it down to this app. Uninstalled and my phone runs like new again.
