Samsung Galaxy S21 Plus 256GB Phantom Violet

For the Samsung Galaxy S21 Plus the ideal option is a USB-C charger that supports Power Delivery up to 25 W, as this enables the phone to use super fast charging and reach a full charge in roughly one hour. Since the charger is no longer included in the box it is best to choose Samsung’s official 25 W adapter or another reliable PD PPS compatible charger to guarantee safety and performance.

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 open the quick settings panel by swiping down from the top of the screen, tapping the power icon and choosing 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 regular use. With lighter usage it can extend close to two days, while heavy activities such as gaming or recording high resolution videos may reduce the battery life to just over half a day.

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