My Optimus Elite goes through what seem like phases of really poor battery life. It can also be really laggy. Also, my status bar is randomly disappearing and reappearing. Any suggestions to help performance. I'm willing to root my phone if that might help, but I am not tech savvy at all (and sometimes you tech savvy people *say* an explanation is "simple" when it's really not for someone who pays little attention to such things!). Thanks for any help!
