We all know that task killers are not just useless, but downright detrimental to your phone's operation. Although, there are some apps that just don't behave properly, eating up resources and burning through your battery. So what are you supposed to do? Uninstall? Freeze with Titanium? Root Task Killer Toolkit offers an alternative. With RTK, you can set apps to go into hibernation mode when they sit in the background too long or Just Force Stop them . The upshot is that you can still use the app normally, but it won't cause problems while your phone is doing more important things.
