The Galaxy S25 Plus and S25 Ultra support 45W fast charging, the same as the S24 and S23 series. But many users of the S25+ and S25 Ultra have reported unexpectedly slow charging speeds.
Notably, Samsung has switched to a different protocol for 45W charging. The phones come with a 3A cable and rely on a 15V input to achieve peak charging speed. However, users with a 5A cable have reported their phones drawing less than 15W on average—an issue that is reportedly software-related and expected to be fixed with an update. In the meantime, affected users can try using the included 3A cable as a workaround.
Most people are facing the issue with third party adapters and cables
While Samsung Italia didn’t reveal much beyond acknowledging the ‘anomaly on charging with the 5A cable’ and confirming they’re working on a fix, users on Reddit have shared more insights into the issue.
Reddit user Brangusler says he has tested his S25+ with multiple power adapters from Anker and “seen it go up to 25-28W maybe once or twice for a brief moment”. “I’m lucky to get a solid 15W and often it hangs out in the 5-10W range for seemingly no reason,” he added.
Samsung uses PD charging, a universal fast-charging standard, for its Galaxy devices. This means your phone should be compatible with a wide range of adapters and cables that support PD, regardless of the manufacturer. However, the current situation suggests otherwise. Ideally, your Galaxy flagship should draw power normally from your laptop charger or any third-party PD-supported charger, such as one from Anker. And this is true for older Galaxy phones such as the S10.
I haven’t seen any comments mentioning issues with the first-party power adapter—which, by the way, you’d have to buy separately, even if you already own five PD chargers. That also defeats the purpose of choosing PD in the first place. Hopefully, this is just a bug and not a deliberate move, and it gets fixed soon.
