1. USE AIRPLANE MODE
Most people don’t know this, but many phones now have a function that allows their cellphones to be used on airplanes. Because airplane mode cuts off all wireless transmissions from your cellular device, it also stops all risk of cellphone radiation too! So if you’re not using your phone for an extended period of time, then either turn it off, or put it on airplane mode. Because the phone uses less energy to operate when wireless transmissions are halted, it also saves battery, which makes your technology use just a tiny bit more efficient.
