Re: S3 Mini..battery drain problem :(
disable wifi direct in the aplication manager...as well as unused apps...i got 3 days on standby...with a few phone calls..
go to settings application manager ...force stop wi fi direct....the little orange download indicator should stop its activity and then just force stop some applications that you dont use...
i hahe found with the battery drain problem that the little orange download indication came on a few seconds in quick intervals...opened my settings and went to wi fi direct and disabled that...problem solved....
