WiFi still showing in battery stats

Can anyone help me? My WiFi is still showing up on the battery stats even when I switched it off. It's shows that it's on all the time. I've even did the software repair using Sony bridge and still problem persist. Am I missing out something? I've switched off the scanning available too. Previous android phones have no problems but this Xperia z5..

I'm running on Android 5.1.1.
Build no. 32.0.A.6.152..

Really appreciate your help.
