RED’s upcoming Hydrogen One smartphone still doesn’t have a concrete release date, but we’re presumably getting even closer to launch, given that the phone has cleared the FCC’s approval process this week, via PhoneScoop.

In addition to confirming that the Hydrogen One is in fact a real device that RED will legally be allowed to sell in the United States, the FCC filing confirms a few smaller details about the phone: it’ll have a 4,510mAh battery, dual SIM slots, and support for all US LTE bands (except T-Mobile’s Band 71).
