The Galaxy S21 charger leaks, no 65W brick in the box
Currently, the 120W charging power of the China-only Mi 10 Ultra is the fastest available, as the battery has to have the respective chemistry, and the phone the suitable charging circuitry for that ultrafast charging session, too.
There are more widespread runner-ups, however, like the Oppo Find X2 Pro or the new OnePlus 8T that come with 65W charging that tops up a 4500mAh unit in less than 40 minutes from depleted state.
Recently, a new Samsung EP-TA865 charger was certified, raising the speculation that the Galaxy S21 Ultra could land with a 65W charger, too, boding well for the top-up of its rumored 5000mAh battery in less than an hour.
So far so good, but, subsequently, the Galaxy S21 series codenames started appearing next to lesser chargers, and today's certification reveal in MyFixGuide shows one SM-G9910, believed to be the local version of the Galaxy S21, will be shipping with Samsung's good ol' SP-TA800 charger. That's the one Samsung packs with the Note 20 Ultra, and is of the 25W variety.
Make of it what you will but either the fast 65W charging will be a prerogative for the more expensive S21 models like the Ultra, or you will have to buy the 65W brick separately, like the 45W one that Samsung sells now. Both cases will be fine, however, provided that Samsung gives us the wherewithal and the charging circuitry to pump the Galaxy S21 models with 65W power.
