    I just got a Samsung Fast Wireless Charger for my Samsung Galaxy Note Fan Edition, and I was wondering one thing.

    I'm pretty sure with cable charging, the phone switches it's power source to the AC adapter after the battery is fully charged (I might be wrong, please do let me know! ) but what about wireless charging? I've heard that after the battery is full, the phone will display 100% but in reality it's draining to 95% before the wireless charger starts charging the phone again and again.

    If you are worried about over charging, that's not an issue (barring any defects of course).

    The bigger concern is keeping it fully charged. Holding the battery above about 75% can cause accelerated breakdown and shorten the overall lifespan.

    You are. The phone always runs from the battery, charger or not. If it's fully charged and the charger is plugged, when the battery charge drops a few percent, the charger kicks in and brings it back to 100%.

    Wireless charging works exactly the same way. (The charger is inside the hone. The thing you plug into the wall is only a power source. So is a wireless charger. The only difference is that a wireless charger's heat ends up heating thew phone, a wall charger's doesn't.)
