menu_default hide_default

I bought my Samsung Galaxy S7 edge a year ago and since then it has been working just fine. A few days ago, I noticed that the device has been suddenly charging very slowly, taking over an hour to get an 87% battery capacity. I have tried everything including wiping the cache and nothing works. Do you know what I can do?

A device that will not charge can present a unique set of problems that can be difficult to fix. For example, if it runs out of battery power and it won't charge, the device can essentially be useless to you. Yet, a device that is charging slowly or one that won't charge completely is one of the most common problems with Samsung devices.


Reasons Why Your Samsung Galaxy is Charging Slowly

Before we get to the solutions, it is important to determine why the device is charging slowly. Some of the most common reasons include the following:

  • The adapter and USB connector you are using could be damaged or not right for the device. Fast charging can only happen when you use the adapter and USB connector that came with the device

  • The device's charging port could also be damaged or dirty, resulting in slower charging

  • A software glitch could also prevent the device from charging faster

The Solutions to Fix the Samsung Galaxy is Charging Slowly

To fix a Samsung Galaxy device that is charging slowly, follow these simple steps;

Method 1: Check the Power Adapter

In order for your device to charge at appropriate speeds, you need to use the original adapter that came with the device. Therefore if you bought another adapter at some point, it is likely that it is a fake adapter which is why the device is not charging fast enough.


Method 2: Check the USB Cable

Your device also comes with a USB charging cable that you connect to a wall adapter and the micro USB port of the device. The original cable can charge the device very fast unless it is damaged in some way which could cause it to fail. The best way to check if the cable is damaged is to test it on another Samsung Galaxy device. A damaged cable can be problematic because the device can show as charging when it is not.


Method 3: Check the Charging Port

If there is nothing wrong with the adapter and cable on the device, then the problem may be the device's charging port. Dust can easily accumulate inside the port hindering it's functionality and causing the device to charge slowly. Cleaning the port regularly can prevent this problem from occurring.


Method 4: Close Background Applications

Sometimes apps running the background can also prevent the Samsung device from charging quickly. To close the apps running in the background, follow these simple steps;

Step 1: Hold the home button to see all the recently used apps.

Step 2: Tap "End all Applications" in the task manager section.

Step 3: Select "RAM" to clear the memory.


This should close all apps running in the background and significantly reduce the time it takes to charge the device.

Method 5: Uninstall Third-Party Apps

Some third-party apps can be corrupt, introducing bugs that can affect the system and cause it to malfunction in numerous ways including charging very slowly. To determine if third-party apps are causing the issue, you need to put the device in safe mode first.


  • To put the device in safe mode, turn off the device and then hold the power key until you see the Samsung logo on the device.

  • Release the power key and then hold the Volume down key until the device restarts and you see "Safe Mode" at the bottom of the screen. If the device is still charging slowly even in safe mode, recently installed third-party apps could be to blame.

  • To uninstall them, go to Settings > More> Application Manager > Downloaded and then select the app you want to uninstall. Tap "Uninstall" and then "OK" to remove the app.

Restart the device to exit safe mode and see if the device is charging a lot faster.

Method 6: Do A Master Reset

A master reset will help remove any settings that could be preventing your device from charging quickly. Here's how to do it.


Step 1: Turn off the device and then press and hold the power, volume up and home buttons at the same time.

Step 2: Release the power button when the device vibrates but keep holding the other two. Release them when the recovery menu appears on the screen.

Step 3: Use the volume down to highlight "Delete All User Data" and press the home button to select the option. Use the power button again to select "Yes- delete all user data" to confirm.

When the process is complete, select "reboot" to restart the device. Please note that this solution will result in data loss.

Method 7: Do A System Dump

A system dump will debug the panel, allowing for the execution of various functions. Here's how to do a system dump.


Step 1: Open the "Dialer" and type *#9900#.

Step 2: Select "Low Battery Dump" at the bottom of the page and then tap "Turn on".

Method 8: Try A Professional Tool

If all the solutions above don't work to fix a device that won't charge slowly, there could be a problem with the Android OS that could be preventing the device from charging.
