Samsung S24 Slow Charging issue – Only 1% Every 2 Minutes? (Solved)

If your Samsung S24 is charging slowly — about 1% every 2 minutes — even with trusted chargers and cables, you’re not alone. Many users have reported this frustrating issue, where charging works inconsistently depending on whether the phone is turned on or off. In some cases, even turning off the device doesn’t help.

This article explains the possible causes and offers practical solutions that have worked for other users.

Symptoms Reported by Users

• The phone charges slowly when turned on, even in Safe Mode.
• Initially, the device charged normally when powered off, but that has now slowed too.
• Multiple chargers and cables were tested, and all worked fine with other devices.
• Cache partition was wiped, which temporarily fixed the issue — but only for a day.
• Charging behavior flipped: in some cases, charging faster when ON instead of OFF.
• One charger was not detected initially but now connects fine.
• Android Auto connectivity was unstable but later improved.

These inconsistent behaviors suggest that the issue may not be hardware-related alone.

Possible Causes of Slow Charging on Samsung S24

1. Software Bug After Update

Many users reported that this issue began after an update to One UI 7. This points to a possible software conflict affecting charging performance.

2. Dirty or Damaged USB-C Port

Even if cables seem fine, a dirty or slightly damaged charging port can interrupt proper current flow. Dust, lint, or debris can cause inconsistent connections.

3. Bad Charging Port

In some cases, the charging port may be physically worn or faulty. Replacing the port has solved the issue for some users.

4. Settings Misconfiguration

If fast charging is disabled in system settings, charging speed may be limited. Certain battery-saving modes may also interfere with charging speed.

5. Power Source Issues

Issues with wall sockets, power strips, or recent electrical events (e.g., storms) can affect how your phone charges — even if they aren’t immediately obvious.
