How to Fix Samsung Galaxy Slow Charging and Adaptive Charging Bugs

If your Samsung Galaxy is charging slowly or experiencing adaptive charging bugs, it can be frustrating and impact your daily usage. This guide provides multiple methods to diagnose and resolve these issues, ensuring your device charges quickly and efficiently.

1. Verify Charger and Cable Compatibility

Ensuring you are using the correct charger and cable is essential for optimal charging performance.

Confirm Authenticity: Use the official Samsung charger and cable or a reputable, high-quality alternative that supports fast charging.
Inspect for Damage: Check both the charger and cable for any visible signs of wear or damage that might affect power delivery.
Test with a Different Set: Try charging your device with another compatible charger and cable to determine if the issue persists.

2. Adjust Adaptive Charging Settings

Modifying adaptive charging settings can help resolve issues where the feature unintentionally slows down the charging process.

Open Settings: Navigate to your phone’s settings and select the “Battery and Device Care” or “Battery” section.
Locate Charging Options: Look for an option related to adaptive charging or optimized charging.
Toggle the Feature: Disable adaptive charging if it appears to be causing slow charging, or toggle between adaptive and fast charging modes if available.
Monitor Charging Speed: Observe if the changes lead to faster charging performance.

3. Update Software and Firmware

Keeping your device up to date can resolve software bugs that may be affecting charging efficiency.

Connect to Wi-Fi: Ensure you have a stable internet connection to download updates.
Access Software Update: Go to Settings and tap on “Software Update” or “System Updates.”
Download and Install: Follow the on-screen instructions to download and install any available updates.
Restart Your Device: After updating, restart your phone and check if the charging speed has improved.

4. Clean the Charging Port

Dust and debris in the charging port can hinder proper connection and result in slow charging.

Power Off the Device: Turn off your Samsung Galaxy before cleaning the port.
Inspect the Port: Use a flashlight to check for any lint, dust, or debris lodged inside the port.
Clean Gently: Use compressed air or a soft-bristled brush to carefully remove any obstructions from the charging port.
Reconnect and Test: Plug in your charger and observe if the device charges more efficiently.

5. Evaluate Battery Health and Charging Behavior

Assessing your battery’s health can help identify if degradation is contributing to slow charging.

Open Device Care or Samsung Members App: Navigate to the built-in diagnostic tools available on your device.
Run Battery Diagnostics: Follow the prompts to perform a battery health check and review the results.
Follow Recommended Tips: Apply any recommended maintenance or calibration tips provided by the app.
Monitor Charging Performance: Check if the battery’s performance improves during the next charging cycle.

6. Use Safe Mode to Identify Third-Party App Interference

Safe Mode helps determine if a third-party app is causing the slow charging issue.

Enter Safe Mode: Restart your device in Safe Mode by holding the power button and then tapping and holding “Power Off” until the Safe Mode prompt appears.
Charge in Safe Mode: Connect your charger and observe if the charging speed improves.
Identify Problematic Apps: If charging improves, consider uninstalling recently installed apps or those suspected of interfering with charging.
Exit Safe Mode: Restart your device normally and test the charging performance again.
