http://forum.xda-developers.com – Hi, I am currently running on Pacman ROM and have Bitdefender Power Tune-Up installed. I was wondering should I switch to Juice Defender (due to the number of downloads + reviews) or remove both completely. I am not on 3G, My WiFi, GPS, Autosync vibration is turned off. Currently, I am gettlng like 1-1.5 days of usage with the above settings. Before this I was on Primo ROM, I could squeeze in like 2 days. Any advise is helpful. (HowTos)
