When you use portable electronic products such as a MacBook, Apple Vision Pro, or connected earbuds in areas where the air is very dry, static electricity can build up on the device or on your body. You might receive a small electrostatic discharge. If you receive a static shock, this doesn't mean that there's an issue with your device.
This condition is similar to dragging your feet across a carpet and receiving a static shock when you touch a doorknob. Instead of the static buildup discharging through your finger when you touch a doorknob, it discharges when you touch your electronic device.
This condition isn't limited to Apple hardware. Static can potentially build up on almost any hardware and could be discharged through the device or when you touch the hardware.
Why does static build up?
Certain environments and actions can encourage static electricity buildup on your electronic device.
- Dry, low humidity environments
- Very windy environments
- Moving your device in and out of your pocket
- Jogging or exercising with your device
- Clothes made with synthetic fibers, like nylon
What can I do to reduce static buildup?
There are several actions that you can take to control static electricity.
- Increase the moisture level in the air. You can use a portable humidifier or adjust the humidity control on your air conditioner.
- Spray an anti-static spray into the air.
- Use anti-static lotion if you have dry skin.
- Wear clothes that are made with natural fibers, like cotton. Synthetic fibers are more likely to hold a static charge.
- Keep your device out of the wind by using a case or leaving it in your bag or pocket.
- Don't frequently move your device in and out of your pockets. Rubbing the device on certain materials can cause a static buildup.
