I really like the products that come from these guys. I've had Go Launcher Ex and Go Keyboard for a while. This past weekend I decided to just go ahead and get everything else they have, so I loaded Go Contacts Ex, Go Locker, and Go SMS. Since doing that, it seems that my battery only lasts about half as long as it did before. Has anyone else and any power issues with these apps? I've tried using the task manager to see which of them is a CPU hog and thus killing the battery quickly, but I couldn't really tell that way.
