Hi! I am kinda new here and just recently got my DHD. I like my phone a lot buy I am bothered by the phone's battery life ranging only for about a 1 day with normal usage. A friend suggested that I should use some custom mode but that would be changing the whole OS. I don't want to change my original OS. So my friend suggested that I just root my phone and then I can tweak it to save on battery. My problem is that there are a lot of complicated ways of rooting DHD and I don't know where to start. Moreover, some of the rooting steps are quite risky and might erase my data or kill my phone. I just want to know if there is some way to only temporarily root my phone with android 2.3.3 without having to downgrade? So that I can unroot it on a later time just to be safe. I know this might be asking too much or may not be possible, but it wouldn't hurt asking. Thanks!
