Why my phone is charging very slow

There are a number of reasons why your device might be charging slowly and most can be fixed without any extra support. First, check that you are using the correct cable and plug and that you're connected to a power socket rather than a laptop or PC.

1Check your charger.

Although most phone chargers and charging cables look similar, there can be a huge difference between their quality and charging speed. It is always recommended to use the charger that came in the box or an official Samsung replacement as these have been specially made for your device.

If you're using an official charger, check to ensure that there isn't any damage to the cable or plug. If you notice any damage, stop using the charger immediately. While checking your charger, look at the charging port on your device to ensure that it is free from any debris.

2Activate Adaptive Fast Charging.

Adaptive Fast Charging is a built-in feature which allows the battery to charge much faster. To use it, you will need to connect your compatible device to a charger that supports fast charging. Fast charging cables and plugs are provided in the box for supported devices.

Please note: Adaptive Fast Charging is only available on certain devices. The feature launched on the S8 and has been included in most devices since. For more information about your device and its specifications visit Samsung Support.

To activate the feature on recent devices:

1.       Go to "Settings", then tap "Device Care" or "Device Maintenance".

2.       Tap "Battery".

3.       Tap the switch to activate "Fast cable charging".

3Check for water and moisture.

Your device will not charge if it detects water or moisture in the USB port. This is a preventative measure to protect the device from damage and corrosion. If your device has detected water in the charging port, it will sometimes display a waterdrop icon on the screen above the charging port. If you see the waterdrop icon, make sure that your device is turned off while it dries.

Most moisture will evaporate by itself within a few hours, but you can also try blowing on the port or exposing it to cool, dry air. If the waterdrop icon has still not disappeared but you are sure the charging port is dry, try turning your device off and on again.

If the icon remains after this, please contact Samsung Support.

4Try Wireless PowerShare.

Wireless PowerShare lets you charge your device using another Qi enabled device, without the need for a charger. For further assistance, find out how to use Wireless PowerShare.

5Close background apps.

Apps are what consume most of the battery life on your device. If you have a lot of apps open at once they will often be functioning in the background and consuming your battery. Make sure that any unnecessary apps are closed when you are charging your phone.

App and software updates are often released to fix any bugs and issues that may be occurring. To ensure that your device is working at the highest possible standard, you should try and ensure that all updates are done as soon as possible.

6Delete third party apps.

On your device you can install apps from the Play Store, Galaxy Store and from downloads on the internet. While the Play Store and Galaxy Store are regulated and checked for malicious activity, apps you've downloaded from the internet are not and can be a security risk to your device. Make sure that you trust the app and the source you are downloading it from before installing it on your device.

If you've noticed that your device is charging slowly and you've recently installed a third-party app, it could be the cause of your issues. Try removing the app from your device to see if your phone returns to normal.

1.       Tap and hold the app you wish to delete.

2.       Tap Uninstall. If this option doesn't appear, drag the app to the top of the screen where it says uninstall.
