Hi everyone. I've only had smart phones for a couple months now and I'm still trying to figure out the best ways to conserve battery and data. I first had the original droid and just last month I upgraded to the droid razr. Love the phone so far but just have a few questions. Does 4G use more battery? When i'm at work I hardly use my phone and it seems like by noon my battery is half dead and i've hardly used it. What do you guys use to conserve your battery? I've also been struggling with certain apps running in the background and continue to open after I close them. I use Advanced Task Killer but then I got in a few minutes later and they are running again. Is there a way to prevent certain apps from starting on their own? Some of them are the crap ware that comes with the phone like motoactive and social networking. I know you can't uninstall them but I'd like to keep them from starting. I've also gone into the task manager and added some to the auto end list but I don't feel like that really does anything. So after looking at a couple posts on here about uninstalling apps I saw someone said to freeze apps with titanium backup. Is this really a good app to use? If so is it worth it to pay for the Pro version? Or are there any other apps out there that could help me with my problems?
