I had major battery issues on my bionic with extended battery. I had the ext battery swapped 2 days ago and yesterday the phone. Unfortunately, after a full 100% turned off charge i am getting the same 7 hours of useage from the phone. I am in 3g area with 4g shut off. I also have wifi and bluetooth off. When i had the phone swapped at verizon they told me to get advanced task killer. I used to have it back in the day but got rid of it over a year ago. Is it needed with ginger bread??? They downloaded it last night to my new bionic. Should I remove it?
