hi mobileman,
In the UK you can buy electro-mechanical timers that plug into a mains
socket, then you plug in your mobile charger into the timer.

I would expect that there should be something similar, available in your area.?

The time can be set in 15 minute increments upto 24 hours.

Price in UK from £2.0 to £5.0GBP depending upon current switching limit.

Regards
EricG

My cell phone uses a Lithium battery, doesn't yours?
A lithium battery has a charger that stops charging when the battery is fully charged, or the battery will catch on fire. Does your charger keep on charging and does your cell phone's battery catch on fire?

My cell phone charger uses 2W from the mains. If I left it running all day every day then the electricity it uses costs next to nothing.

If you want to make a timer then make a clock (the clock ICs are not available anymore) from many logic ICs then have it drive a transistor that drives a relay.

I would assume that accuracy isn't an issue, use a CD4060 oscillator/counter, time delays of several hours or ven days are possible.
