The Samsung Galaxy S21 will discontinue the in-box charger, but may have an optional 65W charger, which will introduce fast charging to challenge models like the OnePlus 8T.

This is according to a new leak from Twitter tipster Snapdrachun 888 5G (via LetsGoDigital), who posted an image of what appears to be a 65W Samsung charging block.

Fast charging has come a long way in the past few years, with some companies like OnePlus offering speeds of up to 65W in their flagships. Recently, Samsung has offered a variety of products related to fast charging. The Galaxy S20 series supported speeds of up to 45W, while the Samsung Galaxy Note 20 dropped to 25W.

Korean regulators already certified a 65W Samsung charger last September, but it is not yet clear when it will appear.

FCC documents already suggest that the Galaxy S21 will be limited to 25W fast charging. Nevertheless, given that the Galaxy S21 Ultra will have at least one additional feature in the form of S-Pen support, there has been some recent speculation that the Galaxy S21 Ultra may have a few surprises in store.

The fact that time has passed since certification in Korea could mean that Samsung's 65W charger is ready for the big leagues. And since other cell phone companies have already begun supporting such fast charging, it is hardly a breakthrough technology that needs a lot of fine-tuning.

Samsung's Galaxy S21 will not ship with a charger, so now is the perfect time to release a premium charging brick as a standalone accessory.

Then again, we may have to wait for the Samsung Galaxy Note 21, due out later this year, which is definitely a good way to make the Note series stand out as the Galaxy S and Z Fold series eat into Note series territory. It will be a good way to make the Note series stand out as the Galaxy S and Z Fold series move into Note series territory. Alternatively, this could be another important feature for the rumored final send-off.

In any case, don't wait long to find out, as the Galaxy S21 is scheduled to launch on January 14. If you want to watch the event, here's how to watch Galaxy Unpacked 2021.

We expect the Galaxy S21 and S21 Plus to get some iterative tweaks: a Snapdragon 888 and a new design for the camera module. The Galaxy S21 Ultra, on the other hand, is expected to feature an enhanced rear camera array, specifically two telephoto cameras (one with 3x optical zoom and the other with 10x zoom). Even with minor upgrades, the Galaxy S21 could be a contender for the Best Smartphones list.
