Does Samsung Include a Charger in the Box?
No — Samsung Galaxy S series phones do not include a charger in the box (since S21 series, 2021). You receive only a USB-C cable.
What to buy:
- For Galaxy S25 Ultra/S25+: Samsung 45W Super Fast Charger 2.0 (~$25–35) or compatible Anker/Baseus PD 45W+ charger.
- For Galaxy S25: Samsung 25W charger or any USB PD 25W+ charger.
Wireless Charging Tips
- Samsung's 15W wireless charging requires a Qi2 or Samsung-branded wireless charger.
- Generic Qi chargers (5W, 10W) work but much slower.
- Samsung Wireless Charger Duo: Charges Galaxy phone + Galaxy Watch simultaneously.
- Remove thick cases (especially metal cases) for wireless charging to work.
Reverse Wireless Charging (PowerShare)
Galaxy S and Z series can charge other Qi devices by placing them on the back:
- Settings > Battery > Wireless power sharing > toggle ON.
- Place a Galaxy Watch, earbuds case, or other Qi device on the back of the phone.
- Charges at ~4.5W — slow but useful for a quick top-up of accessories.
