    Has anyone noticed all the contact points under the battery cover on the S4?

    Anyone know what they're all for?

    2 of them look like contact points for a laptop wireless cards.

    The rest, wireless charging maybe plus some other things?

    Possible wireless charging battery cover ala Palm Pre?

    I see only four, two on the left side of the flash, two on the right. Are those the ones you're talking about? If so, then those are meant for the upcoming wireless charging unit (you'll have to swap the back cover for it to work, so that's why there are contact points).

    Should only need two for wireless charging. The other two could be for external/secondary antenna.

    New back cover could incorporate wireless charging as well as antenna for better LTE reception.
