I also tried reinstalling WL after I saw improvement after uninstalling and it went right back to the quick drain. It;s a real shame cause I like the app.
For those who like Go products, they have a lockscreen app in beta right now. For the moment it is kinda crappy cause you cannot customize it at all (there are a few themes, but you cannot change anything within the theme, not even the wallpaper), but I expect they will flesh out the features as they continue to develop it. But, even in its bare bones form I like it better than the stock lockscreen.
