I don't understand why it's permanently on, on the Prius there was a button to turn it on and off.
It hardly uses any electricity less button to press less things to break. I expect that majority of people want it on all the time. On average commute we are still taking about less than 5% of a batteryI don't understand why it's permanently on, on the Prius there was a button to turn it on and off.
Putting something metallic on the charge pad wont do it any harm... it needs an inductive coil to take advantage of the charge pad... Throwing loose change on a wireless charger does nothing to the charger or the coins. it also doesn't draw any power from the battery unless it is being used. And a phone that is plugged in with a cable will takes its charge from the cable and not the wireless pad, it won't use both. so unless you have a phone on it that isn't plugged into a cable the pad is not going to be doing anything and therefore not draining any precious miles from your battery.I am going to pull the fuse on mine as the phone is normally connected via a cable for Android Auto and charges that way and I don't need to worry about putting anything metallic on the charge pad.
