I9505 Wi-Fi battery drain on every CM/AOSP based 5.0/5.1/6.0

Hey guys! A few weeks ago i've got a used galaxy S4 i9505 (it was always on stock rom.). I wanted to get rid of touchwiz, so i started to explore the forums, and tried as many custom roms as I can, but all of them has the same issue. Every rom I flashed (CM12.1/13, JDCT Optimized CM roms, Octo-M, SlimLP, MoKee AOSP, Dirty Unicorn, JDCT AOSP, Orion, GPE 5.0/5.1) suffers from battery drain because of the wi-fi. Here is a screenshot what i'm talking about.



Even after i turn on the airplane mode, the battery still draining, and the wi-fi is still "active".
I have no problem with the TW based rom (Stock/Imperium), so I don't think it is a hardware related issue.

Here is what i did before the screenshot.
-I was on the latest stock rom (HOL2)
-Flashed the lastest modem (just to be sure)
-Flashed TWRP 2.8.7.2 F2FS
-Did a full wipe (Dalvik/Cache/Data/Storage/Preload/System)
-Changed the cache and data to F2FS
-Flashed Optimized CM12.1
-Wipe Dalvik/Cache
-Flashed OpenGapps 5.1 Pico
-Wipe Dalvik/Cache
-Reboot, connected to my wi-fi, logged in to my google account
-Advanced wi-fi settings-> turned off always scanning, and set the Keep Wi-Fi on during sleep to Never.
-Turned off NFC
-Set mobile data to 2G
-Put my phone on the table and cheked it a few hours later

The result is up there, i didn't installed any mods (no xposed, no kernel, nothing), neither any app from playstore, and i did the same as above with every rom i tried (with the same result)

Please someone tell me, what am i doing wrong? Why is my phone won't go to deep sleep, even though i'm not using any 3rd party app. If someone need logcat or anything just let me know, i would do anything.

(Sorry for the grammatical errors, english is not my native language).
