Charging your smartphone or tablet

There are now a range of options available to you when charging your smartphone or tablet. Wired charging, where a cable is plugged into a power source, is the standard and can include fast charging for compatible devices. There are also wireless options where you can use a wireless charger or use PowerShare to charge devices off of each other.

Wired chargingClick to Expand

Wired charging is the most basic type of charging, available on all Samsung Galaxy devices. Your smartphone or tablet will come with a wired charger in the box. Simply connect the charger to the end of your phone or tablet and plug the other end into a power socket.


Once your device is charging, the battery icon at the top of the screen will change to indicate that it is working. This should happen straight away but if your battery has been completely drained or has been stored without charging for some time, it may take a few minutes for the charging icon to appear.


Later devices come with a cable that allows USB charging (ie you can plug it into your laptop or PC to either charge or transfer data). Please note that if you charge your phone or tablet from a power source like a laptop, your device will charge more slowly than usual. 


Most Samsung smartphones and tablets use either micro-USB (older devices) or USB-C (newer devices) type cables and ports. You will need to use the correct type of charger for your device.


Ensure that you use the right cable and plug when charging, preferably the one that came in the box or a replacement Samsung cable. Different USB plugs have different amperages. If you use the incorrect one for your device or a poor quality one, your device may charge slowly and can even damage your device.   



What are the different types of USB cables and ports?Click to Expand

The cables and ports used with your smartphone and tablet will be either micro-USB or USB-C on one end, with a USB-A type on the other side.


Some of the cables that came with old models will not have the USB-A on the end, but rather just the plug. These plugs will usually have a much lower amperage.  



USB-A is most commonly used with computers or power outlets. When charging, you will connect the USB-A side into the USB-plug or into a laptop or computer. Note that charging via laptop or PC will be slower than using a power outlet.


Ensure you slot the USB-A cable in the correct way so as not to damage it. 




Micro-USB used to be the most common standard USB port and is still found on many older models.  To use it, insert the connection shown into the charging port on your smartphone and tablet. Ensure you slow the cable in the correct way so as not to damage it.




USB-C is the most recent USB development. New Samsung smartphones and tablets come with USB-C ports. USB-C cables allow high speed data transfer and a higher power flow. They are reversible and be plugged in either up or down.  

Fast ChargingClick to Expand

Adaptive Fast Charging is a built-in fast charging feature which allows the battery to charge much faster. To use it, you will need to connect it to a battery charger that supports fast charging. Fast charging cables are currently provided in the box with devices that support fast charging.


When your phone is fast charging, a small lightning symbol will appear on your phone.  


Fast charging USB plugs will have Adaptive Fast Charging written on them.


You can turn Fast Charging on or off in the Settings. You can find this at: Settings > Device Care OR Device Maintenance > Battery > Menu (three dots at the top corner) > Settings OR Advanced Settings > Fast cable charging 


Wireless ChargingClick to Expand

To charge your device wirelessly, you will need a wireless charger. Simply lay the back of your device onto the back of the wireless charger in order for the charging to work.


In order for the wireless charger to work efficiently, we recommend removing any covers or cases before placing your device on charge. 


Note that wireless charging only works with compatible QI certified devices.

Wireless PowerShareClick to Expand

Please Note:

  • The location of the charging coil may vary by model. You may need to adjust the devices to optimum charging angle.
  • Some features may not be available when sharing power
  • PowerSharing will stop if your remaining battery power drops too low
  • The device you are using to charge the other device does not need to be plugged in, but it should have at least 30% charge
  • If you have a cover or accessory on the device, it may affect wireless charging effectiveness. Remove covers for optimum performance. 

Wireless PowerShare allows you to charge another compatible device wirelessly using your device's battery by placing the two devices back to back.


You can either charge devices together (dual charging) by plugging in your Galaxy S10, S10 or S10e and then placing the other device on its back, or transfer power from your Galaxy S10, S10+ or S10e by simply placing them together.


What devices can I use with Wireless PowerShare?


Wireless PowerShare was a feature introduced with the Samsung Galaxy S10 series. You can use your Galaxy S10+, S10 or S10e to PowerShare with devices that support wireless charging:

  • Smartphones that support wireless charging (Qi Standard)
  • Samsung wearables: Galaxy Watch, Galaxy Watch Active, Gear S3, Gear Sport, Galaxy Buds  



Using Wireless PowerShare


1 Pull down the notification panel and tap Wireless PowerShare
2 Place the wireless-charging compatible device you wish to charge back to back on your Galaxy S10 series smartphone.

Note that the location of the charging coil can differ by model and manufacturer, so you may need to move your device to find the optimum angle. Please note that the location of the charging coil may differ by model and manufacturer. You may need to adjust the angle at which you've placed the devices to find the optimum angle.

Troubleshooting - charging slowly or not at allClick to Expand

The most common reasons for slow charging are:

  • using the phone or tablet while it's charging. Draining the battery while trying to charge it will increase the charging time
  • using the wrong amperage plug or a poor quality one. If you are using an older USB plug or one that did not come with your device, your phone or tablet will charge slowly. We always recommend using the official Samsung charger that came in the box, or an official Samsung replacement
  • the charging port or cable is damaged 
  • charging via a laptop or PC.  Charging is most efficient when done via a power socket
  • a case or cover is blocking the flow if the device is charging wirelessly 
  • fast charging is turned off. You can check this in the settings under: Settings > Device Care OR Device Maintenance > Battery > Menu (three dots at the top corner) > Settings OR Advanced Settings > Fast cable charging


If your smartphone or tablet is charging slowly, first check that you are using the right cable and plug, and that neither is damaged.  It is also worth trying a separate charger if you can to see if the problem is with your device or your charger. Make sure that Fast cable charging is turned on and that your software is up-to-date.


If you are trying to use a wireless charger, make sure that any case or cover is removed and that the back of the device is snug against the charger. 


Then, simply turn your device off and on again. If something is causing an issue with your charging, this may resolve the issue.


Try running your device in Safe Mode to see if the problem is being caused by an app. If you have any power management apps installed, try disabling them or uninstalling them to see if they are the problem.


The final step is a master reset. If it is a software issue, most software problems are solved by a full reset.


If none of these work, you may need to send your smartphone or tablet in for repair. Please ensure any content is backed up before sending any device for repair. 



Troubleshooting - not charging and waterdrop icon is displayedClick to Expand

The waterdrop icon will be shown when water is detected in the charging port. Samsung devices will not charge if they detect water or moisture in the USB port. This is a preventative measure to protect the device and prevent corrosion.


Most moisture will evaporate within a few hours but you can also try blowing on the port or exposing to cool, dry air to dry it faster.


If the waterdrop icon has still not disappeared after you are sure the port is dry, then try switching your device off and on again.



Can I use my smartphone or tablet while it's charging?Click to Expand

Yes, you can make full use of your phone or tablet while it's being charged.


However, it will take longer to charge if you're using it while it's being charged.

Rechargeable battery packsClick to Expand

Rechargeable battery packs, sometimes called 'portable chargers', allow you to charge your battery when you're out and about and don't have access to a power socket.


This is particularly helpful if you're travelling and don't know when you'll next have access to a power socket, or if you're out doing a lot of battery-hungry things like playing games or recording a lot of video.


Battery packs usually offer wired charging so you can connect them to your phone or tablet using a USB cable, but there are also wireless battery packs available.  

What are rechargeable battery packs and where can I get one for my Samsung smartphone?

How many charges does a battery pack contain?
Rechargeable Battery Packs come in different sizes and capacities. Capacity is measured in mAH (milliamp). The higher the number, the more battery power it contains.
However, higher-powered devices will need more power to charge than lower ones, so the number of charges will vary depending on the type of device you want to charge and the capacity of the battery pack.
Generally, a higher capacity battery pack of 10,200mAh will be enough to charge a smartphone fully around three or four times (this could be more or less depending on the device), while a lower capacity pack might contain enough for one or two full charges depending on the requirements of the device being charged.
Samsung Rechargeable Battery Packs can be purchased here.
