The short answer is no—cell phones do not attract lightning. The presence of a phone does not significantly increase the risk of a strike. Lightning targets tall, isolated objects and conductive paths, not small handheld devices. Use common sense during storms.

The belief that cell phones attract lightning has persisted for years, but scientific evidence does not support it. Cell phones are small, handheld devices with minimal metal content relative to their surroundings. Lightning is drawn to tall, isolated objects and conductive paths like power lines or wet ground. No documented case exists of a cell phone causing a strike. The real risk comes from being outdoors in an open area, not from the phone itself.
How Lightning Strikes Work
Lightning is a massive electrostatic discharge between a cloud and the ground. A stepped leader descends and is met by a streamer from a tall, conductive object. The strike follows the path of least resistance. Height and isolation are the primary factors. A person holding a phone is not a significant target. The phone’s small size and low height relative to trees, buildings, or even the person’s head make it inconsequential.
According to the National Weather Service, the odds of being struck by lightning in a given year are 1 in 1.2 million. The lifetime odds are about 1 in 15,300. Most victims are outdoors, often under trees or on elevated terrain.
Phone Materials and Conductivity
Modern smartphones contain metals such as copper, aluminum, and gold in circuit boards, but the total metal mass is small (typically 30% of the phone’s weight). These metals are inside a non-conductive plastic or glass body. While a phone can conduct electricity if struck, it does not attract lightning. In fact, the metal in a phone is less conductive than the human body’s saline fluids. The risk of a strike is essentially the same whether you hold a phone or not.
Some people worry that using a phone during a storm could create a dangerous path for electricity. However, the phone’s internal components are designed with insulation and grounding that do not increase lightning attraction.
Safe Phone Use During Storms
While phones don’t attract lightning, using them outdoors during a thunderstorm is still dangerous because you are exposed. The safest action is to go indoors. If you must use your phone, avoid:
- Standing in open fields or under isolated trees
- Using a corded landline (which can conduct electricity)
- Being near metal fences, bleachers, or water
Using a phone indoors is safe. The building’s wiring and plumbing act as grounding paths. However, avoid using a phone while it is plugged into a charger during a storm, as power surges can damage the device.
| Activity | Lightning Risk Factor |
|---|---|
| Holding a phone outdoors | Low – no increased attraction |
| Standing in an open field with phone | High – due to exposure, not phone |
| Using a phone indoors | Safe |
| Using a corded landline | Moderate – can conduct |
Expert Recommendations
The Federal Communications Commission and NOAA recommend staying indoors during thunderstorms. If you are caught outside, avoid open areas, high ground, and water. Remove any metal objects from your pockets (keys, coins) only if they could be uncomfortable, but not because they attract lightning. The key is to minimize your exposure as a tall, conductive object.
In summary, the myth that cell phones attract lightning is false. The real danger is being outdoors in a storm. Focus on shelter, not on your phone. Follow official safety guidelines and stay informed about weather alerts.
