I know that there are already a ton of threads about task killers, whether or not they work, well im just telling my experiences for anyone that wants a straight answer from someone. I have used advanced task killer since the day i bought my droid and was always happy with the performance but i really had nothing to compare it too because i liked being able to kill tasks everytime i put my phone into sleep mode. Well two days ago i finally decided to uninstall atk and see what happened. Let me tell you, my droid is amazing now. It is way faster then it has ever been, no lag, smooth scrolling, its unbelievable. And my battery life is wayyy better, i unplugged it this morning at 630am and it is now 740 and after not killing any programs all day and moderate use (a ton of texting, a good hour of browser and a couple calls) i am still at 30-40% usually by now i would be down to needing a charge! it is amazing, oh and i have never had this much mb free with a task killer. i wish i wouldve grown some balls earlier and just uninstalled atk. I finally believe that the droid does not need a task killer.
