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).

[Stock ROM][OK2 Lollipop 5.0 for Note 3] Odin Flashable stock firmware - N900P

This firmware is the unmodified Lollipop (Android 5.0) firmware downloaded through Samsung Kies. In case you need a copy of the firmware so that you don't have to keep downloading it through Kies, I'm providing you with a copy via the link below. It's odin flashable. Use the "AP" or "PDA" button to flash it onto your phone.

1. Download the stock Android 5.0 ROM (Lollipop) - Sprint N900P ONLY! - http://ift.tt/1RVImtW
2. Download the official Samsung Kies. - http://ift.tt/1UD31kD
3. Download Odin 3 or later. - http://ift.tt/1RVImtY
4. Open Samsung Kies, and connect your phone. Wait for it to install the needed drivers.
5. Open Odin and make sure that it says it's "Added!"
6. Click the "AP" button and open the downloaded ROM.
7. Wait for it to finish verifying the checksum.
8. Make sure that "Auto Reboot" and "F. Reset Time" are the only boxes checked. (The default)
9. Click "Start" and wait for it to go. (Sometimes it gets stuck when it says "Setup Connection" and then you need to unplug your phone and restart Odin. - BE CAREFUL! Make sure it really is stuck or you'll brick your phone!)
10. [Optional] Flash TWRP (twrp.me) or CWM. (clockworkmod.com) TWRP is more free than CWM in the sense that the CWM ROM Manager has a payware version. If you're feeling generous towards those who spend countless hours each day for fun and to make your life a bit easier, throw them a few bucks. Both are freely available.

WARNING: Odin can brick your phone if you don't know what you're doing. If you break it, just buy another $800 device. :P I'm providing these instructions and the ROM without any warranty. You do with them what you feel is best.

Recovery and the red triangle android

I've tried a few methods of getting recovery back but so far have failed. I always end up with that droid and a red warning triangle, which if left long enough it will boot into android on its own.. Any help would be greatly appreciated.

Why does this phone use so much battery while idle?

The question is very tongue-in-cheek. I really love this phone, but the battery life is nothing like a Moto E that my kids use as a WiFi house phone.

The Moto E will sit mostly idle for an entire week, WiFi on the whole time, an hour and a half-ish of SOT, and battery will be 15%. After 7 days.

My ZF2 can only sit idle/wifi for about 2 days even though its battery is ~1000mah larger. My old LG G2 could do 5 or 6 days.

I've experimented with stock and Cm13 with similar results. I'm not looking for 8 hours SOT, I want to take my phone camping and know I can get calls or make calls when necessary. (Odds are, I'll hijack my kids' phone for the trip - but I shouldn't have to do that!)

I guess I'm wondering if this kind of idle drain is common with ZF2? Is it the Intel SOC? Is it screen/touch drivers? Something just seems real strange...
