Step by step

1. Open Charging settings

   Open Settings, Battery and tap Charging settings.

   Done

2. 

   Turn on Fast charging

   Fast charging is on on ours. On the A57 it is one switch; Samsung says the S23 and newer also combine Fast and Super fast charging into this one switch.

   Done

3. 

   See the charging time

   Show charging information shows the battery level and the time until full while the phone charges.

   Done

4. Use a fast charger

   Samsung says fast charging needs an adapter of 15 W or more, and Super fast charging a charger with PPS. A cheap cable can limit the speed. Samsung also says the switch cannot be changed while the phone is charging.

   Done

About this guide

Fast charging is usually on already. If your phone charges slowly, check this switch first, then the charger and the cable. We only looked at these screens on our phone and changed nothing.

The screenshots are from a Samsung Galaxy A57 5G with One UI 8.5 and Android 16, in Dark mode. Other Galaxy phones on One UI 8 use the same menus; on older One UI versions a few names and positions differ.

Good to know

Heat slows charging on purpose. A phone that charges slowly in a hot car or under a pillow is protecting its battery.

Still slow? See Samsung Galaxy charging slowly.

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