The task-killer vs no task-killer argument is as old as nature vs. nuture... well, no, but anyway, it's a big issue for most people. Are these things good to use or do they cause more harm than not? After discovering the application "Auto Memory Manager" (there's at least one other thread about this on these forums - I did do a search) I can say the question has been answered: I don't see any need for a task manager after using Auto Memory Manager. Root access is required, though no custom ROM is necessary if you like to keep your stock theme but are okay with rooting. Anyway, here's what I noticed after using it: My phone is much smoother scrolling between pages. It flies when switching between applications and maybe it's my mind playing tricks on me, but I feel that it's even slightly faster when web browsing. Really, any task you would want to do can be done more quickly. Plus, I feel that I am able to actually multi-task without killing the CPU or reducing my memory to 0 and making the phone feel completely slow and useless. Under the settings, I used the "mild" preset and slid the bar further right (to 50) for "hidden applications" - and I have a 7 page homescreen using helix launcher with over 15 widgets, including news & weather, music, pandora, pure calendar agenda, pure message, and a few other memory-intensive widgets. I always had lag, even with a 1.2 ghz Low Voltage OC'd kernel/ROM (using Bugless Beast right now - but I have used Koush's ROM for a while too) and regardless of my settings with SetCPU, I have always had homescreen lag. I haven't had an ounce of homescreen lag since installing Auto Memory Manager and uninstalling my task killer (Advanced Task Killer). If you find that your phone is still less zippy than you like, go ahead and uninstall your task killer and install Auto Memory Manager and see what happens. I'd recommend trying mild settings first, and if you don't like that, try aggressive settings. Anyway, the purpose of this thread is to spread awareness to the hacking community (hence why I created this thread in the hacking section and not in the applications section) that there may, for some people, be a better option than using a task killer. And, over the course of the day, I've noticed better battery life. Coupled with a Low Voltage kernel, I'm experiencing some insane battery life. Once again, I'm very impressed with the Droid.
