Anyone know what these SmartShare...apps are?

[greydarrah]

Right now I'm at 61% of my battery being eaten up by Android System with 50% left after 3 hours and only 12 minutes of screen time. Very frustrating and I can't figure out what's causing it. Anyway, in looking at applications>all I see 4 apps that start with SmartShare (DLNA, MediaServer, Provider, Push). I was thinking about disabling them, but I can't figure out what they do. Does anyone know what they are for?

Thanks

They are for media casting or sharing between devices.
