Are you experiencing battery drain issues on your Samsung Galaxy S21, S21+, or S21 Ultra? Is your device’s battery draining faster than expected, causing you frustration? Don’t worry, we’ve got some tips to help you with the problem.
With these solutions, you can make the most out of your device’s battery and ensure that it lasts for a longer period of time. Let’s find out how to minimize battery drain on your Samsung Galaxy S21 series.
Tips to Fix Galaxy S21 Battery Drain Issue
1. Keep a check on apps using too much battery
Keep a check on apps and monitor their battery usage. It could be some rogue apps that are responsible for the battery drain. Identify such apps and limit them to prevent further battery drain. Here’s how to do that:
- Open Settings
- Tap on Battery and device care
- Tap on Battery
- Next tap on Battery usage chart
This will show you a detailed list of apps and their battery usage. If you notice anything abnormal in the battery usage, you can choose to optimize those apps to restrict their background activities.
2. Put unused apps to sleep
If there are apps you don’t use much, try putting them to sleep. Some of these apps continue to run in the background and will quickly drain the battery life. To put unused apps to sleep, follow the steps below:
- Open Settings
- Tap on Battery and device care
- Tap on Battery
- Tap on Background usage limits
- Toggle Put unused apps to sleep to On
3. Turn off Always on display
The always-on display feature shows a clock or notifications when your phone is not in used. Enabling this option keeps the screen of your phone on at all times and can quickly drain the battery life.
To turn of always on display, here’s how to do that:
- Open Settings
- Tap on Lock screen
- Tap Always on Display and toggle it Off
If you still want to enjoy the Always-on Display (AOD) feature but want to save on battery life too, you can enable “Tap to show” to show AOD only when you tap on the screen and it will hide itself after few seconds. You can also set it up as per the schedule you want it to show.
4. Adjust the refresh rate
The Galaxy S21 series supports up to 120Hz display which makes your display smooth but it can also quickly drain the battery faster because of its high screen refresh rate. The standard refresh rate is more than enough for most users and won’t have any noticeable difference in the experience between the two.
Here’s how to change the refresh rate:
- Open Settings
- Tap on Display
- Tap on Motion smoothness
- Choose Standard refresh rate and click Apply to confirm the change
5. Use power saving mode
The power saving mode allows you to extend the battery life of your device by restricting certain features such as network usage, data syncing, location check, animation, brightness and other features that uses more power.
To turn on the power saving mode, here’s how to do that.
- Open Settings
- Tap on Device care
- Tap on Battery
- Tap on Power saving mode and toggle it On
6. Turn off features you don’t use
Many people keep ton of features turned on even if they don’t use them and that can potentially drain your phone faster than it should. Features like Edge panels, Motion and gestures, etc are rarely used and it makes sense to just turn them off completely to save on battery. Here’s how to disable some of these features.
- Go to Settings > Display > Edge panels and toggle it Off
- Go to Settings > Advanced features > Motions and gestures and then turn off the features you don’t need
7. Limit app notifications
If you receive a lot of notifications, they could add up to your battery issue. Try turning them off, especially for apps that continuously keep sending alerts which are not important.
Here’s how to disable notification for apps:
- Tap and hold on the app icon you want to disable notifications
- Next click on App info
- Then tap on Notifications
- Now tap on Show notifications and toggle it off
8. Reduce screen brightness
The screen brightness level can also affect your battery life. Try to keep brightness level low to improve the battery life on your phone. To change the brightness level, follow these steps.
- Open Settings
- Tap on Display
- Adjust the brightness on the Brightness scale
You can also turn off Adaptive brightness as keeping it enabled will require more power for it to constantly work and adjust the brightness level depending on the change in the current lighting condition. Here’s how you can turn off the Adaptive brightness.
- Open Settings
- Tap on Display
- Toggle the Adaptive brightness to Off
9. Use Dark Mode
Dark mode can not only reduce eye strain but it can also save battery life as it uses significantly less power as compared to the normal mode. To use dark mode, here’s how to turn it on.
- Open Settings
- Tap on Display
- Select Dark at the top to apply the mode
10. Disable WiFi, Bluetooth, NFC & GPS when not in use
If you are not actively using WiFi, GPS and Bluetooth, make sure you turn them off. Keeping these services active will keep the device scanning for signals in the background and that can quickly drain your battery. To turn these features off, here’s how to do that.
- Go to Settings
- Tap on Connections
- Tap on Wi-Fi and toggle it Off
- Tap on Bluetooth and toggle it Off
- Tap on NFC and contactless payments and toggle it Off
- Scroll down and under “Looking for something else?“, tap on Location and toggle it Off
