We've heard rumors of an Active variant of the Galaxy S5 being in the works with model number SM-G870, and now, a SM-G870A has been certified by the FCC, hinting at the device's imminent arrival. The SM-G870A is expected to be the AT&T variant of the Galaxy S5 Active – according to the FCC, the SM-G870A is 143mm tall and 73.42mm wide, which makes it somewhat larger than the Galaxy S5, though the screen size is the same at 5.1-inch according to import tracking site Zauba. Connectivity features include support for AT&T LTE bands (2, 4 and 17), NFC and dual-band Wi-Fi.
The battery capacity is also supposedly the same as the Galaxy S5's at 2,800mAh (though one FCC diagram lists it as 1,500 mAh). Like the Galaxy S4 Active, it is possible the Galaxy S5 Active will have lesser features in some regards compared to the S5, like a downgraded camera or an LCD screen instead of AMOLED. No concrete details are available yet on when the SM-G870A will be announced or even if it is the Galaxy S5 Active, but you can expect more info to crop up as the days go by.
