Will the rearview mirror heating break if left on all the time?

Leaving the rearview mirror heating on all the time will not cause damage. Normally, keeping this function activated only consumes the battery's power. If the vehicle's engine is not started in time to recharge the battery, it may lead to battery depletion. Principle of rearview mirror heating: The rearview mirror can be heated via the heating wires embedded behind the mirror surface, ensuring clarity. Rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rainwater or fog, eliminating the need for frequent manual wiping and reducing driving hazards. Usage season: Heated rearview mirrors are generally more practical in winter. On winter mornings, drivers often find frost covering almost all the car's windows, which is difficult to remove with a towel. Frost on the front windshield can be cleared by turning on the heater to blow warm air after starting the engine, while frost on the rear windshield can be removed by activating the rear window heating switch, which uses heating wires embedded in the glass.
