Galaxy S27 charging speeds leak show 25W and 45W again

Galaxy S27 charging speeds look unchanged in a fresh 3C listing, with the base model still tipped for 25W wired charging and the S27+ stuck at 45W. That keeps Samsung behind faster charging rates now common on rival Android flagships, and it brings back the same complaint for buyers watching the premium segment.

Samsung Galaxy S27 3C listing points to no upgrade for the base model

The fresh certification filing is the main reason this leak is getting attention. It ties the regular Galaxy S27 to 9.0V/2.77A charging support, which translates to 25W wired charging. That is the same ceiling Samsung has used on its standard S-series phone for years, so there is no sign of a meaningful jump for the base model yet.

If this information holds up at launch, the Samsung Galaxy S27 will likely continue the same pattern buyers have seen before. The entry flagship would stay behind many competing Android phones that now offer much faster wired charging in the premium range. For shoppers comparing devices side by side, that difference can be hard to miss.

This does not mean the phone will be weak overall. But in a market where battery refill time matters more every year, keeping the standard model at 25W may feel conservative. The leak does not point to a new charging strategy, and that is the part many Samsung watchers will notice first.

Galaxy S27 Ultra battery size may grow even if charging stays slow

Leaks around the Galaxy S27 Ultra suggest a possible 5,700mAh battery, which would be a notable step if it comes through. That larger pack could help with day-to-day endurance, especially for users who keep their phones plugged in less often and expect longer screen-on time from a premium device.

There is also talk that silicon carbon battery technology could spread across the lineup. In general terms, that kind of battery approach is often discussed for its potential to improve capacity without making the phone dramatically larger. In this case, it could give Samsung more room to raise battery size while keeping the overall design manageable.

Still, a bigger battery does not automatically solve the charging issue. If the Ultra keeps slow charging limits, it may end up taking longer to top up than rivals with smaller batteries but much faster charging support. That is where the criticism tends to return for Samsung flagships, especially among buyers who value speed as much as stamina.

Right now, the outline of the Galaxy S27 series suggests a familiar split. The base model appears stuck at 25W, the S27+ remains at 45W, and the Ultra may grow in battery capacity without a matching leap in charging speed. That combination would improve endurance for some users, but it would not change Samsung’s reputation for cautious charging upgrades.

For now, the leak is still just a leak, and certification details can only tell part of the story. Even so, the pattern is clear enough to set expectations. Samsung may be preparing a stronger battery setup for the Galaxy S27 family, but the charging speeds themselves still look like the area where the company is holding back.
