Ok, this might already be posted somewhere, but I have not found it if it is so here goes... Are Task Manager programs good or bad. I have always thought that Task Manager programs such as Advanced Task Manager and Free Advanced Task Manager were good. I actually have both apps on on HTC EVO 4G, and use both frequently. I have both because I findthat each catches different open apps. Anyways, I actually had a friend tell me that the Task Manager apps are actually not good for Android phones and actually mess-up the Android operating system. He told me that the Android operating system is actually designed to have a few apps running in the background so that they start quick. He also told me that using Task Manager apps to 'Force Close' apps open in the background is not good for the operating system, and that Force Closing apps actually causes the battery to drain quicker since the Android system has to work to reopen the apps that I force closed. So my question is, does using Task Manager apps to 'Kill' apps, and 'Force Close' apps really hurt the Android Operating System ? Also do Task Manager apps save battery or drain battery ?
