Episode 1478

Veronica from Aptos, CA
Person with cell phone

Veronica wants to know if keeping her phone in Airplane Mode will expose her to less radiation. Leo says yes, it would. Can she also use Wi-Fi calling?

Using headphones instead of putting her phone up to her ear is also better.

iPhone Wi-Fi Calling

Neil traded up his iPhone 8 Plus to the iPhone X, and he wants to know if Wi-Fi calling is a good idea. Should he turn it on?

Would it be of any benefit to Neil? Leo says not really. Quality will vary and if he has a poor connection, that could be an issue.

Jeff from Fullerton, CA
Cell phone

Jeff is worried that using a cell phone is dangerous because of electromagnetic radiation. Leo says that there's no evidence at all that one could get brain cancer from a cell phone.The theory is sensible because electromagnetic radition can damage human cells, but it's in proportion to power output and cell phones are just too low power to do that. People don't really use smart phones as actual phones anymore, anyway. They use them as handheld computers.
