Why Won't My Samsung Galaxy S21 G5 Charge Past 84?

When your Samsung Galaxy S21 G5 stops charging after reaching 84%, several factors could be at play. This guide will help you identify and address common issues related to charging problems, specifically focusing on the 'battery protect mode' and the battery health.

Battery Protect Mode

One of the most common reasons why your phone might not charge past 84% is the 'battery protect mode.' This feature is designed to prevent overcharging and protect the battery from damage. Here's how you can check if this is the issue:

Step 1: Verify Battery Protect Mode

To check if your device is in battery protect mode, follow these steps:

Go to Settings. Select Battery or Power. Tap on Charging or Charge Limit. If available, check the battery settings for a limit on the maximum charge percentage, typically set to 85%.

If you find that your device is set to a charge limit, you may need to adjust the settings or turn off this feature to allow your phone to charge to a full 100%.

The Battery is Probably Shot

If there is no setting for a charge limit, another possible reason for your charging issue is a failing battery. Over time, batteries degrade, and they may not be able to hold a full charge as they once did. Here's how you can determine if your battery is the problem:

Step 2: Check for Battery Health

To assess the health of your battery, follow these steps:

Go to Settings and select Battery. Check for any information about your battery's health or capacity. Most devices have a feature that provides a percentage of remaining capacity.

If the battery health report shows a significant capacity loss, the battery may be reaching the end of its lifespan and might need to be replaced.

Additional Considerations

While the battery protect mode and battery health are common causes, there are other potential issues that could be affecting your phone's charging:

Step 3: Check for Loose or Damaged Cables and Ports

Aloch, consider the cables and charging ports. Ensure that the charger and cable are not damaged and that the charging port is clean and free from debris. A loose connection or damaged component can sometimes prevent the phone from charging fully.

Step 4: Update Your Device

Software updates can often address bugs and improve the overall performance of your device. Go to Settings, tap on About Device, and ensure that your phone is up to date with the latest firmware and system updates.

Step 5: Reset Battery Settings or Perform a Factory Reset

As a last resort, you can reset the battery settings or perform a factory reset. However, proceed with caution, as this will delete all user data and settings. Here's how you can do it:

Go to Settings and select Backup reset. Choose Reset device or Factory reset. Follow the on-screen prompts to complete the process.

After the reset, check if the issue still persists. If it does, you may need to seek professional help or replace the battery.

Conclusion

This guide has covered some common reasons why your Samsung Galaxy S21 G5 might not charge past 84%. Starting with battery protect mode, you can readily check and adjust settings if necessary. Additionally, verifying battery health, checking for cable and port issues, and ensuring your device is up to date can all contribute to resolving charging issues. If the problem continues, consider professional assistance or battery replacement.
