FIXED mine by un-installing some apps I didn't need or use much, before Lollipop battery all day and some but after going to Lollipop battery lasted till mid afternoon only! my guess is as I read is it was an app that worked fine until lollipop!
Press and hold a blank space on the home screen then you should see 3 little icons at the bottom of the screen, click on home screen settings, you should see My Magazine just untick it. Thats how I got rid of the stupid thing :)
