The Samsung Galaxy S25 is described as "Qi2 ready," but it does not fully support the Qi2 standard on its own. This means that while it can wirelessly charge at speeds up to 15 watts, which aligns with Qi2 specifications, the phone lacks the internal magnets necessary for true Qi2 compatibility. Instead, users must utilize a compatible case that includes these magnets to take full advantage of Qi2 features, such as magnetic alignment with chargers and accessories[1][3][7].
If you have a Qi2 charger from another brand, it can still work with the Galaxy S25, but only if you are using a suitable magnetic case designed for Qi2 compatibility. Without this case, the phone will not be able to utilize the magnetic features of Qi2 chargers, although it will charge at standard wireless speeds[1][6][7].
