Yeah the DU battery savor sucks I have the best luck with the CM products like CM cleaner and speed booster that has a antivirus it also has the CPU cooler it cleans up all the junk files and it boost your phone and then also there protection for locking device it's better I think too I think they're the best tool apps out there I got rid of all my DU products yesterday so I just wanted to give him a shot but they sucked and I went back to using all of the CM products they work way better
