10 Tips to Improve Battery Life on Samsung Galaxy S20

Improving the battery life of your Samsung Galaxy S20 is crucial, especially given the power-hungry features of these devices. Here are 10 tips to help you maximize your phone's battery endurance.

1. Adjust the Screen Refresh Rate

The Galaxy S20 series features a 120Hz display, but this high refresh rate significantly drains the battery. To conserve power, set the refresh rate to 60Hz. Go to Settings > Display > Motion smoothness, and select the 60Hz option. This can save you around two hours of screen time compared to using the 120Hz mode[1][4].

2. Lower the Screen Resolution

High screen resolutions also consume a lot of battery power. Reduce the resolution from QHD+ to FHD+ or even HD+ to extend battery life. Navigate to Settings > Display > Screen resolution, and choose a lower resolution. This adjustment can provide a noticeable boost in battery endurance[1][4].

3. Enable Dark Mode

Since the Galaxy S20 devices use OLED panels, enabling Dark mode can help save battery life. Dark mode turns off individual pixels when displaying black or dark elements, reducing power consumption. To turn on Dark mode, swipe down on the notification panel, go to the second panel, and tap the Dark mode button[1][4].

4. Avoid Using Wireless Powershare

The Wireless Powershare feature, while convenient, drains the battery quickly. Avoid using it to charge other devices or accessories unless absolutely necessary, as it can deplete your phone's battery rapidly[1].

5. Use Power Saving Modes

Samsung offers several power saving modes that can significantly extend battery life. Access these modes through Settings > Device care > Battery > Power mode. You can choose from:

Optimized: A balanced mode that is on by default.
Medium power saving: Turns off 5G, the always-on display, limits CPU performance to 70%, dims the screen by 10%, and sets the resolution to FHD+.
Maximum power saving: More aggressive than Medium, it turns off 5G and the always-on display, limits CPU performance to 70%, blocks apps from using data or location, applies Dark mode, and sets the resolution to HD+[1][2][4].

6. Customize Power Saving Modes

You can customize the power saving modes to better suit your needs. For example, you can adjust the brightness level or choose which apps to restrict. This allows you to balance performance and battery life according to your preferences[2][4].

7. Turn Off Adaptive Brightness

Adaptive brightness, which adjusts the screen brightness based on ambient light, can consume more power. To turn it off, go to Settings > Display > Auto brightness, and disable the feature. Instead, manually adjust the screen brightness to a comfortable level[4].

8. Limit Background App Activity

Some apps continue to run in the background and consume battery power. Go to Settings > Device care > Battery > Battery usage, and identify which apps are using the most power. You can then restrict these apps from running in the background to save battery life.

9. Set Up Low Battery Triggers

You can set your phone to automatically switch to a power saving mode when the battery level drops to a certain percentage. Use the Sleep mode accessed from the quick dropdown menu to set various triggers, including battery level, to turn on Power Saving mode automatically[5].

10. Regularly Update Your Software

Keeping your phone's software up to date can often include battery life improvements and optimizations. Ensure you regularly check for and install software updates through Settings > Software update > Download and install. This can help in maintaining optimal battery performance over time.
