The Galaxy S25 Ultra may boast satellite connectivity out of the box. The new Samsung flagship has been certified as a “satellite mobile terminal” by a Chinese regulatory agency. The phone may also support a more efficient 45W charging profile, potentially speeding up its charging.
Samsung to bring satellite connectivity to the Galaxy S25 Ultra
Over the past few years, several smartphone companies have added satellite connectivity to their flagship offerings. Leading phones from Huawei, Apple, and Google offer a satellite-based communication system, a potential lifesaver when you need help but find yourself without network coverage to contact emergency services.
Samsung has been working on a similar feature for a long, and it might finally introduce satellite connectivity with the Galaxy S25 series. The China Quality Certification Center recently certified the Galaxy S25 Ultra’s Chinese version (model number SM-9380), labeling it a “satellite mobile terminal”. It’s unclear if the other two models have this feature.
The same certification listing also mentions 15V/3A charging for the Galaxy S25 Ultra. While it still converts to 45W of power, it’s a new charging profile for the phone. The S24 Ultra supports 45W charging courtesy of 9V voltage and 5A current. In theory, higher voltage minimizes power loss during transmission, i.e., the cable power loss. As such, the device gets more power for efficient and potentially faster charging.
Of course, we are still talking about 45W of power, so do not expect a massive drop in the charging time. However, the new charging profile enables fast charging for more third-party adapters and cables. Many third-party cables top out at 3A of current, although adapters offer higher current and voltage. Limiting the phone to 9V voltage slows down charging to around 27W when using a 3A cable. You can read our Galaxy S25 Ultra preview for more information.
