There is a video going around on Facebook showing a guy taking apart the battery inside his Samsung phone and finding a coiled antenna inside. He says that this is spying on every phone user and “recording every photo of yours.” He also urges folks to remove this unnecessary part of the battery and his proof is that the phone still works without it. The video has folks tearing apart their batteries and removing the piece.

Unfortunately, what he is saying isn’t rooted in any fact. The piece inside is an NFC antenna, which powers Near Field Communication features. If you’ve ever used your phone to tap to pay at a cash register or put your phone back to back to another phone to exchange a file or picture, you’ve used it.

I took apart a battery to show you what’s inside and explain the real deal.
