I haven't had superb battery life in the past couple versions of SS, but I have been traveling a lot and attributed it to spotty cell signals. Since installing 4.6, I have found another culprit: Launcher. It's used way more battery than it should, after a full day yesterday both it and display were tied for the top spot, but display had been on for close to two hours. I'm not running a live wallpaper or widgets that should be sucking a lot of juice, but those are listed separately anyway. What could be the problem?
