There are many topic on the forum against the use of a Task Killer for your Evo running Froyo. While I agree with those posters on Froyo does a efficient job at managing RAM usage, there is a good reason to use Automatic Task Killer for your Evo. Specifically, you want to set Automatic Task killer to kill the Browser app and the Map app after your lock your screen (1-5 minute delay is suggested).
The reason for this: Evo browser does not exist the page when you leave the browser, it just run your browser in the back ground. If the web page have things that automatically update every so often (ads, news feeds, etc) the browser will stay active in the back ground using up your battery for the CPU and 3G, and sometime even GPS . So I found that having ATK automatically kill your browser after you lock your screen is helpful.
I found the same to be true of Navigation also, if you forget to exist Navigation and left it running in your phone's back ground, it will kill your battery in no time.
So while I agree with most people here in the forum that Froyo does a good job managing memory usage in general. There are very good reasons to use Automatic Task Killer for your Evo.
I hope this is useful for people that still struggling with battery issues.
