S21 Poor Battery Life May Caused by Camera Sensor

The Samsung Galaxy S21 Ultra users have been complaining about a strange battery drain issue on their devices, but Android’s regular battery stats monitor doesn’t find anything wrong. Instead, they found that the camera sensor may cause this only by utilizing advanced battery monitoring apps.

That could be why Samsung does not take this seriously and did not respond positively to all related complaints.

Tips to Fix Samsung S21/S22 Battery Draining Fast

Have S21 Ultra Battery Draining Fast issue? Try the following fixes:

Fix 1: Enable Dark Mode

Enabling Dark mode on Samsung Galaxy S21 Ultra phones prevents night-time battery depletion. In addition, it allows you to maintain the quantity of light shown by each pixel. It is also worth noting that dark mode is less taxing on your eyes.

To enable the Dark Mode on S21 Series, follow these steps:

Step 1: Navigate to the Settings menu.

Step 2: Tap the Display button.

Step 3: Enable the Dark Mode.

Fix 2: Switch to Standard Refresh Rate

The Galaxy S21 Ultra is among the most powerful phones available. It has a high refresh rate or 120Hz display. Battery consumption is directly linked to increased refresh rate, believe it or not. When your smartphone begins to overheat and deplete energy, you can reduce the frame rate and set it to the regular rate, i.e., 60Hz.

To modify the refresh rate on the Galaxy S21 Ultra, follow these instructions:

Step 1: Launch the Settings and then to Display.

Step 2: Navigate to the Motion Smoothness tab.

Step 3: Change the default refresh rate, 120Hz, to the standard refresh rate, 60Hz.

Step 1: Navigate to Settings and choose Device Care.
