Since i used the free nova. I sign in to fb app. But fb app doesnt appear as batt hog app in the graph.. This evening i bought the full app. Fb n fb msgr doesnt appear too. Dono why these two main culprits doesnt appear anymore. and the customization and material design does what i think ss shud have done to their tw.. very good apps. Those of u who are on nova. Do u see fb n fb msgr as main hoggin app in ur battery usage?
