What to do if your phone is not charging

There are several reasons why your device might not charge, and most can be fixed without any extra support. The most common reasons for a device failing to charge are:

  • a faulty cable, charger, socket or adapter
  • dirt or debris in the charging port
  • third party apps interrupting the charging process
  • a software update is required

Find out what to do if your tablet is not charging.

Check your charger

The first step is to check to see if the problem is related to your charger or charging cable. 

1 Are you using an official 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 and are designed to maximise battery life. Check to make sure that you are not using counterfeit accessories.

2 Check for damage

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.

3 Try a different cable and plug

Even if there is no obvious physical damage to the cable or the plug, try using a combination of different cables and plugs to eliminate these as a potential problem. To make sure that your cable / plug works, you can also try using it to charge a different device.

4 Try a different power source

Once you are sure that your cable / plug works, try plugging them in to a different power source. For example, connect the charger to a power socket rather than a laptop or PC.

If you have determined that your charging cable or plug is not working or needs replacing, you can buy a new one from our accessories page


Clean the charging port

One of the most common causes of charging problems is the charging port becoming clogged with dirt, dust, or debris. Dirt or lint can build up inside the charging port and prevent the charging cable from engaging properly with the charging contacts inside the port. This can stop your phone from charging properly or prevent it charging at all.

Follow the steps below to clean your charging port:

1 Power off your device
2 Shine a torch into the charging port and look inside. If you can see dust or dirt, especially if it is covering the metal charging contacts, the charging port needs cleaning
3 Try gently blowing into the charging port to remove dust and debris

Please note: do not insert any object into the charging port. This can result in damage to the charging port.

4 If the charging port is still clogged, take it to a professional to be cleaned

Check for water and moisture

Your device will not charge if it detects water or moisture in the USB port. This is a security 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 gently 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, clear the cache for USB:

1 Open the Settings
Tap settings
2 Tap Apps
Tap apps
3 Tap the filter icon
Tap the filter icon
4 Tap the switch to show system apps
Tap the switch next to show system apps
5 Tap OK
Tap OK
6 Scroll down, then tap USBSettings
Scroll down and tap <b>USBSettings</b>
7 Tap Storage
8 Tap Clear data and Clear cache

Once you've cleared your cache and data, try charging your phone again to see if this has resolved your issue.


Reboot your device

To check if it is a software-related issue, and your device still has charge remaining, try re-booting it.

1 Turn the phone off
2 Wait 10 seconds
3 Plug in the charger
4 Turn on the phone

You could also try performing a soft reboot. The key combinations differ slightly depending on the model of your device, but with most devices you should hold the Power and Volume Down keys.


Update your software

Software updates are regularly released by Samsung and can solve a range of device software problems.

1 Open the Settings app
2 Tap Software update
3 Tap Download and install

Your device will check for available updates. If there is an update for your device, you will be asked to download and install it. If there are no updates available your device will display that 'Your software is up to date.'


Check for damage

Physical damage such as a cracked screen or case may affect the performance of your device. You should also check your charging port for any signs of damage.

Insert a charging cable into the charging port of your phone. The charging cable should fit snugly into the port and should not feel loose. Using a torch, look inside the charging port to check for any damage.

If your charging port is damaged, you can book a repair to get your device fixed.


Try a wireless charger

If you think the problem is related to wired charging and you have a wireless charging compatible device, try charging your device using a wireless charger. Make sure to remove any cases or covers first and lay the back of your device onto the wireless charger, making sure to line up the charging coils to establish the strongest possible connection.

Wireless charging

Try Wireless PowerShare

Wireless PowerShare lets you charge your device using another Qi enabled device without the need for a charger. To charge your device wirelessly you will need a wireless charging compatible device.

Read our FAQ "How to use Wireless PowerShare" for help if you are trying to charge your device using Wireless PowerShare.

Replace the battery

If the battery loses charge quickly, takes a long time to charge, or doesn't charge at all, it might be time for a new battery. If you have a Samsung Galaxy S5 or older phone, your device has a removable battery so you can purchase a new one and replace it yourself. 

If you have a Samsung Galaxy S6 or newer mobile phone, your device has a sealed battery compartment. This means that ordering a new battery is classed as a repair and you may be charged a service fee. This price is dependent on your specific phone and its physical condition.

To request a repair or to check the price for a battery replacement go to Samsung Repair.

For further assistance, find out what to do if your device is charging slowly, not switching on or keeps restarting.


If none of the suggestions above resolve your issue, you can book a repair or visit your closest Samsung Service Centre for further assistance.

If you're experiencing unusual behaviour on Samsung mobiles, tablets or wearables, you can send us an error report or ask us a question in the Samsung Members app.
