Quick Charging not working when paired to Smartwatch?

I have an LG G4 and have been enjoying Quick Charging using multiple Qualcomm Quick Charge 2.0 chargers I bought since I got it. Have noticed recently though that it doesn't charge as fast as it used to. Though the G4 doesn't really post a notification on screen that it is fast charging, usually by an hour our charging I'm at full capacity and ready to take it to work (don't charge overnight, just charge an hour after I wake up then by the time I leave, i'm good to go).

Now after an hour, it's still below 40% charging! I'm now wondering if it has something to do with my new smartwatch which I paired to my G4. Bought a gorgeous Huawei Watch last week and it's paired to my G4. I'm thinking if it being paired--meaning it constantly getting information from the watch even when charging--is causing the phone to constantly wake up and stop fast charging?

I just tested this theory a few minutes ago. Turned off bluetooth in my G4 and it seems fast charging went back coz phone charging ended faster. Will experiment more in the coming days. But has anyone experienced the same? Do Smartwatch paired phones keep the phone from Quick Charging?

Mine seems finicky even without being paired to a smart watch. It's my opinion that the QC2.0 abilities of the G4 aren't fully up to the certification spec (which may be why it wasn't advertised). My M8 would quick charge regardless of what I did with it. My G4 will sometimes charge at a lower than stock rate simply by having the screen on. I'm talking only 150-300mA according to Ampre and it doesn't act like that on the stock charger.
