2. Dirty or Damaged Phone Charging Port

A charging port clogged with dust, lint, or debris is a common cause of phone charging issues. Samsung and Android devices with USB-C ports are particularly susceptible to debris accumulation, which can prevent proper contact between the charger and the port. Physical damage to the port, such as bent pins or corrosion, can also halt charging.

Signs of a Problematic Charging Port

  • The charging cable feels loose or doesn’t stay securely connected.
  • Charging is intermittent, requiring you to wiggle the cable.
  • Visible debris or corrosion in the port.

How to Clean and Fix the Charging Port

  • Power off your phone to avoid electrical damage.
  • Use a non-metallic tool, like a wooden toothpick or plastic spudger, to gently remove debris from the charging port.
  • Apply compressed air to dislodge stubborn particles.
  • If corrosion is present, use a small amount of isopropyl alcohol (90% or higher) on a cotton swab to clean the port.
  • For physical damage, visit a certified repair center to replace the charging port.

3. Faulty Charging Cable

The charging cable is often the weakest link in the charging process. Repeated bending, twisting, or exposure to heat can weaken the cable’s internal wiring, leading to a phone charger not working. USB-C cables, commonly used in Samsung and Android devices, are durable but not immune to wear.

Diagnosing a Faulty Cable

  • Test the cable with another phone or charger to isolate the issue.
  • Look for physical damage, such as fraying near the connectors.
  • Try a different cable with the same charger to rule out adapter issues.

Solutions for a Faulty Cable

  • Replace the cable with a high-quality, certified USB-C cable that supports your device’s charging standards.
  • Opt for braided cables for added durability.
  • Store cables properly to avoid bending or tangling.

4. Software Glitches Preventing Charging

Software issues can also cause a phone not charging problem. Updates to Android or Samsung’s One UI may introduce bugs that interfere with charging. Background apps or corrupted system files can also prevent the phone from recognizing the charger.

  • The phone displays a charging icon but the battery percentage doesn’t increase.
  • Charging stops unexpectedly or is inconsistent.
  • The phone overheats during charging, triggering safety protocols.

How to Fix Software Glitches

  • Restart your phone to reset temporary software issues.
  • Update your device to the latest Android or One UI version via Settings > Software Update.
  • Boot the phone in Safe Mode to disable third-party apps: Press and hold the power button, then long-press “Power Off” until Safe Mode appears.
  • If the issue persists, perform a factory reset after backing up your data (Settings > General Management > Reset > Factory Data Reset).
  • For persistent problems, contact Samsung or your device manufacturer for software diagnostics.

5. Battery Health and Degradation

Over time, smartphone batteries degrade, reducing their ability to hold a charge. This is a common issue for older Samsung and Android devices, especially those used heavily for streaming or gaming on platforms like Tech Today. A degraded battery may cause the phone to stop charging altogether.

Signs of Battery Degradation

  • The battery drains quickly, even when not in use.
  • The phone shuts off unexpectedly despite showing a charge.
