There is a certain small excitation current that is generated by the step down transformer in the charger. It is that current that keeps the charger warm to the touch even when there is no phone plugged into it.
Nothing will happen because the connector plates on the battery aren't touching the prongs on the phone.
Yes, a diode can be used in a battery charger to prevent reverse current flow from the battery to the charger when it's disconnected. This protects the charger from potential damage.
No it is really not possible
There are literally tons of ways that you can save money and feel good about it, but one of the less common ways to do this that not many people know about is to use a wireless cell phone charger. These chargers do not require being plugged into an electrical socket, but can charge your cell phone just as powerfully! Using a wireless cell phone charger can really cut down on electricity bill costs if an entire family with cell phones makes use of one. This can help free up more electrical sockets in the house and can cut down on electricity usage.

A battery charger does one thing. It charges a battery, and starts with whatever charge is in the battery and goes from there. Running an automobile battery down will shorten it's life.

Yes, if the charger does not automatically shut down when the battery is fully charged.
NO, but it does when the reception of the signal is at the "last bar".
Even when a phone is off - it still uses a minute amount of power from the battery. It constantly checks the circuitry to see if the power button has been pressed. Even a fully-charged battery will eventually run down in a phone that's switched off.
A: Simply by adding a series resistor from the battery charger. WHAT VALUE? find the current required and use it to IR drop the voltage
