For the Samsung Galaxy S21 Plus the recommended option is a USB-C charger that supports Power Delivery up to 25 W, as this allows the phone to use super fast charging and reach a full charge in about one hour. Since no charger is included in the box it is best to choose Samsung’s official 25 W adapter or another trusted brand that supports PD PPS to ensure reliable and safe charging.

To turn off the Samsung Galaxy S21 Plus you need to press and hold the side button together with the volume down button until the power menu appears, then select Power off and confirm. Another option is to swipe down twice from the top of the screen to open the quick settings panel, tap the power icon and choose Power off. If the phone becomes unresponsive you can force it to shut down by holding both buttons for several seconds.

The Samsung Galaxy S21 Plus is equipped with a 4800 mAh battery that typically lasts a full day of normal use including browsing, social media and video streaming.
