Battery drain whenever connected on wifi

Hi guys!
I have a jb ip5 on 6.0.2 and having battery problems when on a wifi..
I only have zeyphyr and ifiles from the jb..nothing else..i am getting great phantom usage when on wifi but battery is fine if i stick to edge..

never connected to cloud,facetime,imessage, no push on mail or ical..

why is this happening?
