Wireless Charging and heat

[Gary_Berg]

I've got an Anker Qi charger and I find that when I leave my S6 on it and let it charge up that it gets distinctly warm to the touch. GSAM indicates temps around 90-95 in a 70F room. My in-line power meter says it is still drawing about a half amp at 5V even though the phone says 100% charged and the charger indicates the same.

Is this normal? I don't want to cook the battery.

When I charge with a cable the phone settles down to room temperature.

I have not noticed any heat like that with my aftermarket Qi charger.
Are you using it with a BT app playing music or something?

Just sitting there charging. Not using it at all. I figure if it's drawing a half amp when the battery is charged it's got to send the power someplace. While charging the phone heats up slightly (and draw 1.3amps), the problem is after it hits full charge and continues to draw 0.65amps.

I've reached out to Anker support, but I don't know if the behavior is normal for Qi chargers or not.

I had been using one of the small round Anker Qi chargers at work, but it got much hotter than my other Qi chargers, and popped or clicked probably due to the heat causing some expansion of the case. The Anker has been demoted to a spare after I replaced it with a round clear Pleson I got on Amazon, which I am quite please with. I also have a Captain America shield version of the Samsung Qi charger - and it works fine.
