Step by step

1. 

   Turn on Fast charging in Charging settings

   Open Settings, Battery, Charging settings. On the Charging settings page, tap the switch next to Fast charging. On our Galaxy A57 it was on and not greyed out while the phone was charging. Samsung says that from the Galaxy S23 series, Fast charging and Super fast charging are combined in this one switch.

   Done

2. 

   See the charging time

   Show charging information shows the battery level and the estimated time until full when Always On Display is off or not shown. It was on on our Galaxy A57.

   Done

3. 

   Read what the phone says while charging

   With the screen off, the Always On Display shows the charging state. On our Galaxy A57, plugged into a Mac, it read Fast charging: 44% and 1 h 20 m until full.

   Done

If you do not see this option

• You also see Fast wireless charging. Our Galaxy S26 (Korean model SM-S942N, One UI 9) lists Fast wireless charging under Fast charging in Charging settings; both were on. Our Galaxy A57 has only Fast charging, as it has no wireless charging.

  

• No Charging settings row Samsung's older page puts it under Device care, Battery, Charging, so look there on phones with an older One UI. Source: How to fast charge on your Galaxy device
• No Fast wireless charging switch Our Galaxy A57 lists only Show charging information and Fast charging. Samsung names Fast wireless charging next to Fast charging on models that charge wirelessly. Source: How to enable fast charging and fast wireless charging on your Samsung Galaxy device

If this does not work

• The switch will not change Samsung's older fast-charge page says you cannot turn the feature on or off while charging, so unplug first. On our Galaxy A57 the switch was not greyed out while charging; we did not try to change it. Source: How to fast charge on your Galaxy device
• Still slow with the switch on Samsung says Super fast charging may not be available if the charger does not support PPS, and that third-party cables that do not meet the required specifications can stop charging now and then. It suggests a genuine Samsung cable. Source: How to enable fast charging and fast wireless charging on your Samsung Galaxy device
• Charging from a computer Samsung says fast charging may not work when the phone is connected to a PC or a standard USB device. On our Galaxy A57 the Mac's USB port still showed Fast charging on the Always On Display. Source: Samsung Galaxy device may appear to be charging slowly or not charging at all

About this guide

Fast charging was already on on our phone. If your phone charges slowly, check this switch first, then the charger and the cable.

The screenshots are from a Samsung Galaxy A57 5G with One UI 8.5 and Android 16, in Dark mode, charging from the USB port of a Mac.

Good to know

Samsung says the charging speed may drop by itself when the phone or the air around it gets warm, and that turning the screen off helps.

Still slow? See Samsung Galaxy charging slowly.

In short: Settings, Battery, Charging settings, Fast charging on; a compatible charger and cable.
