Power issues


Follow the below troubleshooting steps in turn to determine the reason for your device charging slowly, not switching on, or switches off/restarts unexpectedly


If you have checked all the below steps and the issue is still occurring, you may have a fault with your device. You can find ways to contact us here.


Slow charging 


Do you have an official Samsung charger?

Some chargers that aren't provided by Samsung may not charge the device correctly. They might not provide enough amperage to charge the device, or too much therefore affecting the battery.

Incompatible chargers can be harmful to the battery and may short out in extreme circumstances.


The correct amperage for your device can be found in the device's manual and the amperage of a charger can normally be found on the plug.


Is there any damage to your charger?

Only use an undamaged charger in good condition


Check your charging port. Do you see any damage?

If there is damage to your charging port, you may need to book your device in for repair. Click one of the blue buttons at the bottom of this article for our contact details.


Are you using wireless charging?

Make sure that the device's back sits against the centre of the charging centre and remove any foreign materials between the device and the charger.

See here for more troubleshooting when using a wireless charger


How are you charging the device? 

Your device will charge faster if plugged into a wall socket, than if it is plugged into another device such as a laptop.

Clear the cache partition on your device.

1. Turn your device off, if it isn't off already.

3. Using the volume down button, scroll down to wipe cache partition.

Does this happen when you are using a particular app?

Ensure that you only download apps from reliable and safe sources such as Galaxy Apps or the Google Play Store.

How much space do you have left on your device?

Does your device feel particularly hot when it switches off?

If your device becomes too hot, it might switch itself off automatically. This can be after running for a long time or when running more power-intensive apps, or if you have insufficient storage.


Ensure you keep your software up-to-date as such updates can enhance your device's performance and help reduce its operating temperature.
