Galaxy devices have an internal coil to support wireless fast charging and wired adaptive fast charging. This built-in feature allows the battery to charge much faster than standard charging methods.
Notes:
The name of these settings may vary depending on your device model and software version.
Charging speed may vary depending on the charging environment and other factors.
Fast charging may not be supported on some models.
Because there are differences based on the appropriate cables and adapters (TA), it is suggested to use Samsung-certified accessories that fulfill the specifications.
