Why is the battery on the Galaxy S21 draining so quickly? What can I do about it?

Here are some ideas to help you get the most out of your Galaxy S21, S21+, or S21 Ultra battery life(s21 battery draining fast).

1. Keep an eye on apps that are draining your battery.

Keep an eye on your apps and their battery utilization. Rogue apps may cause the battery drain. Identify and ban such apps to avoid future battery drain. Here’s how you can do it:

1. Open the Settings menu and select Battery and Device Care.
2. That should tap the battery.
3. After that, select the Battery Usage Chart.

It will provide you with a comprehensive list of apps and their battery usage. If you see any unusual patterns in your battery usage, you can select to optimize those apps to not run in the background.

2. Turn off any apps that aren’t in use.

Try putting apps to sleep if you don’t use them very often. Some of these apps will continue to function in the background, draining the battery quickly. Follow the steps below to put useless apps to sleep:

1. Open the Options menu.
2. Select Battery and Device Care from the drop-down menu.
3. That should tap the battery.
4. Select the Background Usage Limits option.
5. Toggle Set the sleep mode for unused apps to On 3. Always on display should be turned off.

When your phone is not in use, the always-on display feature displays a clock or notifications. Enabling this option keeps your phone’s screen on all the time, which can quickly drain the battery.

1. Here’s how to switch off the always-on display mode:
2. Open the Options menu.
3. Select the Lock screen option.
4. Toggle off Always-on Display by tapping it.

If you wish to keep the Always-on Display (AOD) function but save battery life, you can enable “Tap to show,” which will display AOD only when you tap the screen and then conceal it after a few seconds. You can even program it to show on the schedule you desire.

4. Increase or decrease the refresh rate

Because of its high screen refresh rate, the Galaxy S21 series supports up to 120Hz display, making your display smoother and draining the battery faster. For most people, the regular refresh rate will suffice, and there will be no discernible difference in the experience between the two.

To adjust the refresh rate, follow these steps:

1. Open the Options menu.
2. Select the Display option.
3. Select Motion Smoothness from the menu.
4. To confirm the change, select Standard refresh rate and click Apply.

5. Switch to power-saving mode.

The power-saving mode helps you extend your device’s battery life by limiting network usage, data syncing, location check, animation, brightness, and other power-intensive services.

Here’s how to activate the power-saving mode on your computer.

1. Open the Options menu.
2. Select Device Care.
3. That should tap the battery.
4. Toggle the power saving mode by tapping on it. On

6. Turn off any functions that you aren’t using.

Many people leave a lot of functions turned on even if they aren’t using them, which might cause your phone to drain faster than it should. Edge panels, Motion and gestures, and other features are rarely utilized. Therefore it makes sense to switch them off totally to save power. Here’s how to turn off some of these options.
Toggle it under Settings > Display > Edge panels. Off
Turn off the features you don’t need by going to Settings > Advanced features > Motions and gestures.

7. Keep app notifications to a minimum.

If you get a lot of notifications, this may exacerbate your battery problem. Turn them off, especially if you’re using an app that keeps giving you notifications that aren’t relevant.

Here’s how to turn off app notifications:
To turn off notifications, tap and hold the app icon.
After that, go to App Info and then to Notifications.
Toggle off Show alerts by tapping on it.

8. Dim the display’s brightness

The brightness of your screen can also impact how long your battery lasts. To extend the life of your phone’s battery, keep the brightness low. Follow these procedures to adjust the brightness level.

Open the Settings menu and select display.
On the Brightness scale, adjust the brightness.

You can also disable adaptive brightness because keeping it on will use more power to constantly work and adjust the brightness level in response to changes in the current lighting environment. Here’s how to disable the Adaptive Brightness feature.

1. Open the Options menu.
2. Select the Display option.
3. Toggle the Adaptive Brightness switch to the Off position.

9. Switch to the dark mode

Dark mode not only helps to decrease eye strain, but it also helps to save battery life by using much less power than regular mode. Here’s how to enable dark mode on your device.

1. Open the Options menu.
2. Select the Display option.
3. To use the mode, go to the top and select Dark.

When not in use, turn off WiFi, Bluetooth, NFC, and GPS.

Make sure you switch off WiFi, GPS, and Bluetooth if you aren’t using them. Keeping these services turned on will keep the smartphone hunting for signals in the background, draining your battery quickly.

Battery Life on device? Fixing It

The Samsung Galaxy S21 is a powerful Android phone – when the battery lasts(s21 battery draining fast). Overall, Samsung nailed the S21. Iconic 120Hz AMOLED display, excellent cameras, and lightning-fast processing. It all comes in a sleek body for a starting price of $800. (which is often lowered thanks to endless Samsung offers).

The Galaxy S21 has a lot going on, but battery life is a concern. The S21’s 4000 mAh battery is enough for most users; however, it falls short for those with more demanding workflows. While there’s no way to double the S21’s battery life instantly, there are methods users can do to maximize battery life per charge.

Use Samsung’s built-in optimization tool to enhance the S21’s battery with a few taps quickly. Tap ‘Battery and device care’ in the Galaxy S21’s Settings. The S21 is given a score out of 100 based on battery life, storage, and memory. At the bottom of the page, the ‘Optimize now’ button initiates an optimization sweep, dismissing unnecessary background apps, monitoring battery usage, and identifying program crashes. It’s unnecessary to do this every time, but it’s a good idea (or whenever the S21 starts losing battery life faster than expected).

Other Galaxy S21 Battery Saving Strategies

On the same Device Care page, tap ‘Battery’ to see the Galaxy S21’s full battery options. Aside from showing remaining battery life and current usage, a few other power-saving tools are available. The first function shown is ‘Power saving mode,’ which is useful when the S21’s battery is running low, and a charger isn’t available. Users may toggle it on on the Battery page by touching the toggle, but tapping the ‘Power saving mode’ moniker takes them to a page explaining how it works. That can also customize the power-saving mode to turn off the always-on display, limit CPU speed to 70%, and dim the display by 10%.

Users may pick which apps should be put to sleep or deep sleep on the Battery screen. Most users don’t need apps like Best Buy or Netflix running in the background, so it is wise to add them to these lists. The Galaxy S21 automatically adds apps to these lists, but users may also add or remove them manually. Once again, go to the Battery page and confirm that ‘Adaptive battery’ is activated. This function “limits battery usage for rarely used programs.”

 

The final tip concerns the Galaxy S21’s screen. While the 120Hz refresh rate looks excellent, it quickly drains the phone’s battery. Turning off the 120Hz refresh rate may help extend the life of an S21. So, open the Settings app and select display> Motion Smoothness > Standard > Apply. With these suggestions, the Galaxy S21 should have optimal battery life.
