If your phone is on top of a microwave while it's running, it can potentially experience several negative effects due to the electromagnetic fields generated by the microwave oven. Here are a few things that could happen:
Interference: The strong electromagnetic fields produced by the microwave oven can interfere with the normal functioning of your phone. It may cause temporary disruptions or distortions to the signal reception, resulting in dropped calls, poor call quality, or slow data speeds.
Damage to the phone's electronics: Microwaves emit microwave radiation, which can potentially damage electronic devices. The radiation can induce electrical currents and voltages in the phone's circuitry, leading to malfunctions or even permanent damage to the internal components.
Heating: Microwaves are designed to heat food by emitting microwave radiation. If your phone is on top of the microwave, it can absorb some of the radiation and potentially heat up. This can cause the phone to overheat, which may lead to battery damage, screen malfunction, or other hardware issues.
To avoid these potential risks, it's generally recommended to keep electronic devices, including your phone, away from operating microwave ovens. It's best to store your phone in a safe location, such as a different room, to ensure it remains unaffected by the microwave's radiation and to maintain its proper functioning.
