Understanding and Troubleshooting Samsung Slow Charging Issue

"Why does my phone charger keep switching from fast charging to slow charging??? I can fix it by unplugging and plugging it back in but sometimes it takes several times before it starts fast charging again. It doesn't matter if I'm using my phone or not."

- From Reddit

Are you frustrated with your Samsung device charging slower than expected? Slow charging is a common issue faced by Samsung users, and it can disrupt your daily routine, especially when you need your phone to charge quickly. Understanding the root causes of slow charging on Samsung devices and knowing how to address them effectively is crucial. In this guide, we'll delve into the reasons behind slow charging Samsung devices and provide actionable solutions to fix the issue, ensuring you can charge your device efficiently.

Part 1. What Causes Samsung Charges Slow

Understanding the reasons behind slow charging helps you tackle the problem efficiently. Common culprits include:

• Damaged hardware such as cables, chargers, or charging ports.
• Disabled fast charging settings, limiting your device's charging speed.
• Battery-draining apps or processes consume power during charging.
• Outdated software or misconfigured settings affecting battery performance.

These factors create a chain of inefficiencies, slowing down the charging process. Addressing them step by step can restore optimal performance.

Part 2. How Do I Fix My Samsung Slow Charging?

From the reasons above, we can see that the slow charging of Samsung phones is not only due to the device itself but also influenced by human factors. To address this issue, in this section, we have listed 7 methods you can try.

Solution 1. Check the Charger and Cable

Often, slow charging is a result of faulty hardware. Are you using the original Samsung charger and cable? Non-certified or damaged accessories can lead to slower charging speeds. Using the correct hardware is your first step toward resolving charging issues.

• Inspect the charger and cable for physical damage or wear.
• Test your charger with another device or use a different outlet.
• Ensure the charger meets your device's wattage requirements (e.g., 25W for fast charging).

Solution 2. Activate Adaptive Fast Charging

Have you enabled fast charging on your Samsung device? These settings allow your device to charge faster when supported accessories are connected. Without this setting, even the best chargers won't deliver optimal speed.

Step 1. Go to "Settings" > "Battery and Device Care" > "Battery" > "More battery settings".

Step 2. Toggle on "Fast charging".

Solution 3. Try Wireless PowerShare

How to turn off slow charging on Samsung? In certain situations, Wireless PowerShare can be a lifesaver. This feature allows you to charge your Samsung phone wirelessly from another device.

Step 1. Activate "PowerShare" from the Quick Settings panel.

Step 2. Place your Samsung phone back-to-back with a compatible device.

Solution 4. Optimize Battery Usage

Unnecessary processes and apps may run in the background, slowing down charging. Ask yourself, are you optimizing your device effectively?

Step 1. Open "Settings" > "Battery and device care".

Step 2. Tap "Optimize Now" to clear redundant processes and improve charging speed.

Of course, you can go to "Settings" > "Apps" to force-stop any unused apps.

Solution 5. Delete Third-Party Apps

Third-party apps can sometimes interfere with your phone's performance, causing issues like Samsung tablets charging slowly. To identify and remove problematic apps, Safe Mode is a valuable tool. Safe Mode disables all third-party apps temporarily, allowing you to observe your phone's behavior in a "clean" state. If slow charging improves in Safe Mode, a third-party app is likely the culprit.

Step 1. Press and hold the "Power" button until the power menu appears.

Step 2. Tap "Power Off" to shut down the phone completely.

Step 3. Press and hold the "Power" button again until the Samsung logo appears.

Step 4. When the logo shows, immediately release the "Power" button and press and hold the "Volume Down" button.

Step 5. Continue holding the "Volume Down" button until the phone finishes booting.

Step 6. Look for the words "Safe Mode" in the bottom-left corner of your screen. This indicates that the phone is running without third-party apps.

Step 7. Use your phone normally and charge it while in Safe Mode. If charging speeds return to normal, a third-party app is likely causing the issue.

Step 8. Exit Safe Mode by restarting your phone normally. Navigate to "Settings" > "Apps".

Step 9. Review recently installed or suspicious apps. Look for apps you don't recognize or that coincide with the start of the slow charging issue.

Step 10. Tap the app you wish to remove, then select "Uninstall". Restart the phone and test charging speeds again.

Solution 6. Update Phone Software

Is the Samsung phone charging slowly? Outdated software may introduce bugs that affect battery and charging performance. When was the last time you updated your phone? Regular updates keep your phone optimized for performance.

Step 1. Navigate to "Settings" > "Software update".

Step 2. Tap "Download and Install" to ensure your device is up-to-date.

Solution 7. Fix with Samsung Repair

If none of the above fixes work, your phone may have deeper software or hardware issues. Then, the ultimate method you can try is using an Android system repair tool. Android Repair can help you resolve various system issues, such as slow charging and black screens. Check out the following features of Android Repair:
