The Samsung fast-chargingfunction

You should first know that you can already charge your Samsung more quickly with simple measures such as by reducing power consumption during charging. You can find out how to do that on our page How to charge your phone faster.

This page here is primarily about the fast-charge function on the Samsung mobile phone, which is supported by most models and can be set individually. If fast charging should work on a Samsung, you need a fast charger with at least 15 watts of power output. With the optimal charging accessories and fast charging activated, your Samsung charges up to 60% in 30 minutes.

Compatible models

Two charging technologies have become established for fast charging: Qualcomm Quick Charge (QC) and Power Delivery (PD). The charging power in the Quick Charge technology has constantly improved. Depending on the model, Samsung Galaxy mobile phones support fast charging either with Quick Charge or with both technologies.

The following Samsung models are compatible with fast charging:

• Samsung Galaxy S24: PD 3.0/QC
• Samsung Galaxy S24+: PD 3.0/QC
• Samsung Galaxy S24 Ultra: PD 3.0/QC

Setting fast charging for Samsung

You can activate and deactivate fast charging on the Samsung. Depending on the Android version installed, you can set the function in a different place in the settings. For example, on the Samsung Galaxy A40 under > Device care > Battery > More Battery Settings > Fast Charging via cable. If fast charging doesn’t work on your Samsung, first check whether the fast-charge function is actually activated in the settings. If you mainly charge your Samsung overnight, you should deactivate fast charging so as not to place an unnecessary strain on the rechargeable battery.

Suitable Samsung quick chargers

If your Samsung has a Micro-USB or a USB-C connector, you can quickly charge it with the corresponding Micro-USB-to-USB-C or USB-C-to-USB-C charging cable. More important than the charging cable for the fast-charge function is the power output of the power supply unit used. This should deliver at least 15 watts to ensure the fast charging of the Samsung. Look in the manual of your Samsung for information on how many watts your rechargeable battery needs to be charged optimally.

It is crucial whether the charger provides at least this power output. A power supply unit that is too powerful doesn’t harm your Samsung – the mobile phone only draws as much power as your rechargeable battery needs.

Suitable chargers from Hama

For fast charging on Samsung mobile phones, Hama offers quick chargers with the Qualcomm Quick Charge or Power Delivery charging technology as well as combined power supply units. The two technologies can be found combined in the Hama power supply units more and more often, so that the chargers enable fast charging for all Samsung models. The suitable charging current is recognised and adapted by the respective connected device. As a result, the Samsung does not overheat during charging and the battery is protected.

Samsung super-fast charging

Samsung fast charging is not enough? The super-fast charging function enables a Samsung such as the Galaxy S21 to be charged almost twice as fast. This function also has to be activated to be used optimally: Settings > Device Care > Battery > More Battery Settings > Super Fast Charging.

The most important thing: For super-fast charging, the Samsung needs a charger with USB Power Delivery technology and at least 25 watts of power output.

Fast charging does not work

If fast charging on your Samsung no longer works, you should first check in the settings whether the fast-charge function is actually activated. If this is the case, restarting often helps. Another cause can be that you have accidentally connected an old power supply unit with insufficient charging power. This supplies too little power to charge the Samsung quickly. Fast charging on the Samsung only works with the right fast-charging accessories.
