Samsung Galaxy S21 Plus 256GB Phantom Gold

For the Samsung Galaxy S21 Plus the recommended charger is a USB-C adapter 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 the charger is not included in the box it is best to choose Samsung’s official 25 W adapter or another reliable PD PPS compatible charger to ensure safe and efficient 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. You can also do this from the quick settings panel by swiping down from the top of the screen, tapping the power icon and choosing Power off. If the phone stops responding 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 regular use. With lighter usage that includes calls, messaging and occasional browsing it can extend up to two days, while heavy activities such as gaming or recording high resolution video may shorten the battery life to just several hours less than a day.

The Samsung Galaxy S21 Plus is guaranteed to receive four major Android updates and five years of security patches. This means the device will be supported up to Android 15 with One UI 7, and security updates will continue until early 2026. Starting in 2025 these patches are released quarterly instead of monthly.
