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.
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.
You can also book a repair.
he first step is to check to see if the problem is related to your charger or charging cable. 1Are 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 an official Samsung charging cable as these have been specially made for your device and are designed to maximise battery life.
Using an unofficial charger can even cause damage to your phone. Official chargers are designed to have the correct voltage for your device whereas alternative chargers may operate to a different voltage. Check to make sure that you are not using counterfeit accessories.
Find out more about the different types of USB cables.2Check 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.3Try 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.4Try a different power source
Clean the charging port
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.
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:1Power off your device2Shine 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 cleaning3Try 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.4If 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.
Please note: It is not always obvious when water has entered your phone. Just exposing your phone to a humid environment can cause water to enter the phone, even if there is no visible sign.
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 and your device still has power, clear the cache for USB:1Open Settings
2Tap Apps
3Tap the filter icon
Please note: in older versions of Android “system apps” can be found from the options icon (three vertical dots).
4Tap the switch to show system apps
5Tap OK
6Scroll down, then tap USBSettings
7Tap Storage
8Tap 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.

What is a Schematic Diagram?
Circuit diagrams (aka. electrical diagram, elementary diagram, electronic schematic) show how electronic components are connected together. Each component is represented by a symbol, with wire represented by a connector.
What are Hardware Solutions?
Is a collection of visual information in the form of paths, measuring points, value information for comparison, which is very useful for technicians, in their work technicians often need to reference data other than schematics such as reference values from normal machines, and take measurements by frequently opening schematics and PCB layouts.
To read and understand a cellphone schematic diagram, we must have some knowledge about basic electronics like resistors, capacitors, transistors, integrated circuits, etc.
