Samsung remains committed to its 45W fast charging standard. However, the Galaxy S25+ and Galaxy S25 Ultra come with a hidden charging upgrade that many users may not be aware of!
Galaxy S25+ & S25 Ultra Support 45W Charging with the In-Box USB Cable
Samsung has made charging more convenient with the Galaxy S25+ and Galaxy S25 Ultra by enabling 45W Super Fast Charging 2.0 using the bundled USB-C cable. Unlike previous Galaxy model such as the Galaxy S24, which required a separate 5A cable to achieve 45W speed the S25+ and S25 Ultra can now achieve full-speed charging using the included 3A USB-C to USB-C cable.
Why This Matters
Earlier Samsung flagships supported 45W charging but required a separate, high-power (5A) USB-C cable to deliver 10V at 4.5A. The default 3A cable in the box only supported 25W charging. Now, with the Galaxy S25+ and S25 Ultra, Samsung has optimized charging to work at 15V and 3A, reaching the same 45W output without the need for an extra purchase.
Does This Work on the Base Galaxy S25?
No, this upgrade only applies to the Galaxy S25+ and Galaxy S25 Ultra. The standard Galaxy S25 is still limited to 25W fast charging with the included cable. If you own the base model, upgrading to the S25+ or S25 Ultra is the only way to take advantage of this improved charging experience.
Faster, More Convenient Charging with Any 45W USB PD PPS Charger
Galaxy S25+ and S25 Ultra users can pair their devices with any USB Power Delivery (PD) PPS charger that supports 45W charging and enjoy super-fast speeds without hunting for a separate 5A cable.
How Fast Does 45W Charging Work?
✅ Up to 75% charge in just 30 minutes
✅ Full 100% charge in about 60 minutes (1 hour)
By eliminating the need for a separate 5A cable, Samsung has saved users both time and money, making fast charging more accessible and convenient.
Final Thoughts
Samsung may not be chasing 100W+ charging speeds, but with the Galaxy S25+ and S25 Ultra, it has made 45W Super Fast Charging 2.0 easier and more user-friendly. If you want fast charging without the hassle of buying extra accessories, these models offer the best experience yet!
