Fast charge your Galaxy phone

S20 is fast charging on a table

If your phone just died, or if it's about to, it isn't the end of the world. You can charge it back to full power in no time by using the Samsung Adaptive Fast Charger. This charger comes with your phone, and it provides an extremely quick charging time. You can use Fast charging, Super fast charging, and Wireless charging on your Galaxy phone. If you need replacement chargers, you can purchase them from our website.

Note: Only use Samsung-approved charging devices. Samsung accessories are designed to maximize the battery life for your phone. Using other accessories may invalidate your warranty and cause damage.

Charging the phone

Before you start charging, make sure you are using the correct charger for your phone. When you're ready, all it takes is three easy steps to get your phone charging at top speed.

Insert the USB cable into the USB port on your phone. Make sure the USB cable is connected to the charging adapter, and then plug the adapter into a standard outlet. For the fastest charging time, plug the charger directly into a power outlet. Plugging the USB cable into a computer or another device will lengthen the charging time.

When your phone is done charging, unplug the charger from the phone and the adapter from the wall.

If your phone is not charging, there are a couple things that could be causing the problem. However, if your fast charger doesn't work at all, it should be replaced. If it's under warranty, you can request service. If not, you will need to purchase a new one.

Fast, Super fast, and Fast wireless charging

Most Galaxy phones can use Fast charging and Fast wireless charging when you really need your device to be up and running again. When you plug in a Samsung Fast Charger, your phone will automatically turn on the Fast cable charging feature. This feature should be on by default, but you can also turn it on manually.

Super fast charging is only available on select phones, and you need to use the charger that came with the phone or a 25W or 45W Samsung approved adapter. However, regular Fast charging can be used with a standard Fast Charger.

  1. To use a charging feature, first navigate to and open Settings, and then tap Battery and device care.

  2. Tap Battery, and then tap More battery settings.

  3. Tap the switch next to Fast charging, Super fast charging, or Fast wireless charging.

  5. Once the phone is fully charged, you may disconnect the charger from the device and from the outlet.

Note: The S20 Ultra is the only phone that supports 45W charging.
