I'm sorta new to the EVO/smartphone thing, so I'm not yet "assimilated" to my phone; I don't have to hold it in my hand 24x7 (yet). But, I do want to try to extend my battery life. I've tried several "task killers" and have read a couple threads about pros & cons. So here's what I'm thinking: AIRPLANE MODE. Whenever I know I'm going to be without my phone for several hours, I'm just going to put in into AIRPLANE MODE. What do you think?
