Sprint HTC Hero :: Worst Battery Killer - Prevents Sleeping From Cold Boot - No Interaction Required

Merely turning your phone on may be enough to prevent it from sleeping. What I'm about to tell you is 100% repeatable. I've done it about ten times now; it has happened every time. I'm running the stock Android 2.1 ROM from Sprint. <Background> When Android boots, it preloads a huge number of apps into RAM. Essentially, it's starting JVM processes and loading the classes of applications without actually executing any of their code. Android does this to reduce the lag you would feel when activating one of these apps. These preloaded apps are said to be EMPTY. There's no real penalty for preloading these apps since they're loaded in the background in otherwise idle CPU cycles and their processes will be terminated as needed to free up RAM for applications you begin using. </Background>

Although it should be impossible, one of those preloaded apps is preventing the Hero from sleeping. By process of elimination, I have found which one it is: Footprints.............
