Posts on Reddit and the Samsung Community site (via Android Police) have noted slow charging speeds or even interruptions to power when plugging in their new Plus or Ultra Samsung. This is despite the chargers working fine with these users' previous Samsung phones, and the S25 showing the fast-charging label while powering up.

The problem is also cropping up for S25 owners using Samsung's official 45W charger and the bundled 5A USB-C cable. Some users have found that disabling the fast charging feature allows the phone to charge with the 45W adapter, though at a slower pace.

Some Galaxy S25 Ultra and S25+ users are facing charging issues. Samsung acknowledges the problem and promises a fix in an upcoming software update. Heres the details.
