Does the Galaxy S25 Support Wireless Charging?
Yes — the Samsung Galaxy S25 supports wireless charging at up to 15W via Qi2, plus 4.5W reverse wireless charging.
The Galaxy S25 supports 15W Qi2 wireless charging and 4.5W reverse wireless charging.
Quick Answer
Yes, the Samsung Galaxy S25 supports wireless charging. It uses the Qi2 standard and charges at up to 15W wirelessly. It also supports 4.5W reverse wireless charging.
Wireless Charging Specifications
| Spec | Detail |
| Wireless Charging | Yes |
| Maximum Speed | 15W (Qi2) |
| Standards | Qi, Qi2 |
| Reverse Wireless | Yes, 4.5W |
| Wired Fast Charging | 25W |
The Galaxy S25 is fully backward-compatible with older Qi chargers, though these will operate at lower speeds (typically 5-10W). For the full 15W experience, a Qi2-certified charger is required with a USB-C power adapter rated at 25W or higher.
What Chargers Work with the Galaxy S25?
The Galaxy S25 is compatible with three categories of wireless chargers:
Qi2 Chargers (Recommended) — These deliver the maximum 15W speed. Look for the Qi2 logo on packaging. These chargers need a 25W+ USB-C power adapter for full-speed operation.
Standard Qi Chargers — Any Qi-certified pad will charge the S25, typically at 5-10W. Good for overnight charging when speed is not critical.
Samsung Wireless Chargers — Samsung wireless charging stands and pads are optimised for Galaxy devices and reliably deliver 15W with compatible power adapters.
Real-World Charging Times
Based on the Galaxy S25 approximately 4000 mAh battery:
| Charger Type | Estimated Full Charge |
| 5W Qi pad | ~4.5 hours |
| 10W Qi charger | ~2.5 hours |
| 15W Qi2 charger | ~2 hours |
These are estimates. Actual times vary based on screen use during charging, ambient temperature, and power adapter quality. Use the Charging Time Calculator for a personalised estimate.
Common Issues with Galaxy S25 Wireless Charging
Slow charging speed — The most common cause is a power adapter that cannot supply enough wattage. A 5W USB charger cannot power a 15W wireless pad at full speed. Use a USB-C PD adapter rated at 25W or higher.
Charging stops intermittently — This usually indicates the device is sliding off the charging coil, overheating, or a poorly made charging pad. Try repositioning the phone or switching to a flat pad instead of a stand.
Phone gets warm — Normal up to about 40C. Wireless charging is slightly less efficient than wired (typically 80% efficiency vs 95%+), so some heat is expected. Excessive heat indicates a problem — remove the case and check for obstructions.
Case blocking charging — Most cases work fine. Exceptions: thick cases over 3mm, cases with metal plates or magnetic inserts, and cases with RFID cards built in.
Tips for Best Wireless Charging Performance
- Use a 25W or higher USB-C PD adapter with your Qi2 charger
- Place the phone centred on the charging pad, not at the edge
- Remove the case if using one thicker than 3mm
- Avoid charging in direct sunlight or in a hot car
- Use a flat charging pad if you want to keep using the phone while charging
