Hi, been searching for this type of thread but the ones I saw are seem to be outdated of posts. . Please move this If I missed the same. . Just want to ask the s4 users here.. are battery saving apps really worth? (for UNROOTED) units?? IF YES, then what are your recos?? I checked Juice Defender but it has not been updated for over a year. . . I am trying Battery Doctor now.. its my 2nd day, but haven't seen any improvement.. I think this is my 2nd month (1x a month) of emptying my battery before charging.. (close to 2hours before full charge) Any thoughts please?
