Galaxy S25 charging speed leaks, and there’s bad news

The Samsung Galaxy S25 series is still months away from its expected launch date, but leaks have already revealed details about charging for the Galaxy S25 Ultra. Now, a regulatory filing may have just revealed information about charging for the rest of the series.

Gadgetschina spotted a regulatory filing for the Galaxy S25 (SM-S9310) and Galaxy S25 Plus (SM-S9360) on China’s 3C certification website. We were able to confirm the listing, as shown in the screenshot below.

The filing reveals that the Galaxy S25 Plus has a maximum charging speed of 45W (15V/3A), while the base Galaxy S25 maxes out at 25W (9V/2.77A). Unsurprisingly, neither device comes with a charging adapter.

Charging speeds are disappointing for the base Galaxy S25, since Samsung’s base models have been stuck with 25W wired charging since 2020’s Galaxy S20. In other words, 2025 will mark the sixth straight year that the base Galaxy flagship phone has had 25W charging. There’s more to fast charging than peak power, but it still takes over an hour to juice up the Galaxy S24’s 4,000mAh battery.

In contrast, the OnePlus 12 (80W or 100W), Nothing Phone 2 (45W), and Motorola Edge 2024 (68W) all offer faster charging speeds on paper and bigger batteries. And these phones are all available in the US, too.

Either way, the Samsung Galaxy S25 is expected to once again pack a 4,000mAh battery and feature the same rear cameras as the Galaxy S24, so don’t expect a major hardware upgrade.
