Does charging ever stop?

I was under the impression that newer kernels stop charging when the battery gets to 100% so as to prevent heating the battery. I'm using Google's wireless charger and it draws a constant 1.1 Watts even when the battery is fully charged.

The charger draws a constant 1.1W or the device does?
If the former, I wouldn't take issue with that - the charger doesn't know that the device is fully charged; it's the device that determines that it's fully charged, and it stops drawing current when appropriate. Meanwhile the charger is still outputting the same charge signal.

The charger uses a transformer to output the appropriate voltage for your device. The primary winding of the transformer will always be drawing current from the mains socket. That does not mean the device, your battery, will be drawing from the secondary winding, however.

I'm measuring at the wall with a kill-a-watt. If I remove the charger from the N7 wattage drops to 0, so the AC adapter works OK.

If I snap the wireless charger back onto the N7, it draws 1.1 watts even if N7 is fully charged.

So I'm thinking that the wireless charger bypasses the kernel and attempts to charge regardless, which is what makes the N7 warm?
