Samsung is preparing for the global release of its highly anticipated Galaxy S25 series, but recent information from the FCC certification has raised concerns about one aspect of these flagship smartphones: their fast charging speeds.

The Samsung Galaxy S25, S25+, and S25 Ultra models were recently spotted on the FCC certification, signaling an upcoming release. While these premium phones are expected to launch around January 2025, following the timeline of the Galaxy S24 series, it appears that Samsung is lagging behind its competitors in terms of charging technology.

The Galaxy S25 series will come with model numbers SM-931U, SM-936U, and SM-938U. These devices support 5G, Bluetooth, NFC, GNSS, and dual-band WiFi. However, one glaring issue that stands out is the charging capabilities of the new lineup.

Samsung Galaxy S25: Stuck with 25W Fast Charging

The Samsung Galaxy S25 will reportedly ship with the EP-TA800 charging adapter, which supports only 25W fast charging. This is a significant disappointment, as it lags behind its Android competitors, many of whom have already adopted faster charging speeds. Even Apple has surpassed Samsung in terms of charging performance in recent models.

For comparison, devices from other manufacturers are now supporting up to 120W or 150W fast charging, offering users significantly faster charging times. In contrast, Samsung’s 25W charging speed on the Galaxy S25 feels outdated, especially considering that flagship smartphones are now expected to provide faster and more efficient charging solutions.

Galaxy S25+ and Galaxy S25 Ultra: A Slight Improvement but Not Enough

While the Galaxy S25+ and Galaxy S25 Ultra models are listed with a 45W fast charging adapter, which is a step up, it still falls behind some of the latest high-speed charging standards in the industry. The Galaxy S25 Ultra, in particular, will also feature the S-Pen, which could be a significant draw for users seeking a more feature-packed device.

However, there’s a potential setback in the wireless charging department. The Galaxy S25 is rumored to only support 9W wireless charging, which is a downgrade from the 15W wireless charging offered by its predecessor, the Galaxy S24. If this is true, Samsung may be taking a step backward in this area, which will likely disappoint fans looking for faster and more efficient wireless charging solutions.

A Missed Opportunity for Samsung Galaxy S25 Series

In a time when fast charging is a key consideration for smartphone buyers, Samsung’s Galaxy S25 series may have missed an opportunity to lead in this area. With competitors offering significantly faster charging speeds, Samsung risks falling behind unless it addresses these limitations in future updates or releases.

We’ll have to wait for the official Galaxy S25 launch to confirm these details, but as of now, it seems that 2026 might be the year when we finally see a major upgrade in Samsung’s charging technology.
