    Default Galaxy S5: What is the hidden circuit in the battery cover?

    Hi there. I seem to be the only one who has noticed this, as I have searched everywhere online for an answer! If you hold the back cover of the S5 up to the light, there is a hidden circuit embedded in the plastic. This seems to induct power from the battery, which it sits next to, but what is it for? Is it something to do with s health, or is it a passport style tracking device?

    As a guess, this could be an antenna. Either for the wireless radios, NFC, Bluetooth, or that sort of thing. Can you post pics??

    There are two different Samsung Galaxy S5 back cover,the normal back cover and the wireless charging battery cover.
    The wireless charging battery cover:
    Utilizing the Qi global standard for inductive charging, you can charge the Galaxy S 5 phone without the need to plug in. Once the battery cover is installed, simply place your device directly onto the Samsung Wireless Charging Pad (sold separately) and your phone begins to charge .

    Sounds like Micle Arons nailed it. Thanks for the pic though, I was curious what exactly you were talking about. The pic seems to line up exactly with what a wireless charging setup would look like

    I think it's nfc. I'm not sure how it works but the phone also knows when you remove the cover. The standard non charging cover definitely has a sensor of some type in there.
