Hey I am using Beautiful Widgets for the small home widget.
To be honest, I was "borrowing" the product for a while and never had a problem. Ever since I bought it, my batter drains like crazy and I get "problem loading widget" a lot.
Now, I also upgraded to 2.2 around the same time, and I've heard about the facebook drain, but facebook doesn't show in my battery usage screen, while Beautiful Widgets is the 1st item (well first application) and is using 16%!
PS: The unlock animations isn't on.
