12 tips to improve battery health for your Windows Acer Swift GO laptop:-

Change the power mode
Changing the power mode is one of the best tips to save your laptop’s battery life. If you want to save your battery’s life, we recommend setting the power mode to a more efficient battery mode.
Click on the battery icon in the taskbar
Then drag the slider and choose a power mode
If your Windows laptop is unplugged, you will get four options: battery saver, better battery, better performance, and best performance. If it is plugged in, you will get the same options, with the exception of battery saver.

Check power and sleep settings
You can improve battery health by reducing the display and sleep timeout. The shorter the times, the longer your battery lasts.
Open Settings ( Windows key + I)
Click on System
Click on Power and Sleep on the left pane
Then, use the drop-down menus on the right pane to shorten the display and sleep time out when running on battery power.

Use battery saver
Setting your Windows laptop to battery saver mode will also improve battery health. Battery saver mode is automatically triggered whenever you are running below 20% charge. It disables push notifications, background apps, and email syncing. You can raise the threshold above 20% to activate the battery saver if it does not interrupt your normal activities.
Open Settings
Click on System
Click on Battery on the left pane
Then, turn on the battery saver or raise the threshold to a percentage level you like.

Reduce the brightness of your screen
You can easily increase your laptop's battery life by reducing your screen's brightness. The brighter your screen is, the more power it consumes. We recommend lowering your screen’s brightness to an acceptable level.
Click on the notification icon on the taskbar.
Then, use the brightness slider to reduce screen brightness.
Turn off the keyboard backlights
Keyboard backlights also use battery power. You should keep them turned off when they are not needed to increase your laptop's battery life.
Use the function key (fn) to toggle the backlight on and off
You can also use the Windows Mobility Center to control lighting

Disable background app
You should disable the number of apps running in the background to increase your laptop's battery health.
Open Settings
Click on Privacy
Scroll down on the left pane and click on Background Apps
Then, on the right pane, toggle off the option to “Let apps run in the background.”
You can also toggle off select apps if you want to allow some of them to run in the background.

Close apps that use lots of power
Apps that use a lot of power affect your laptop’s performance and drain your battery’s life. You can increase battery health on a laptop by checking the guilty apps and closing them.
Open Settings
Click on System
Click on Battery on the left pane
Scroll down to check the power consumption history for the past week or 24 hours.
Find the guilty app and click on it. Then, toggle off the switch for “Let Windows Decide” and select “Never” to restrict the app from running in the background.

Turn off Bluetooth and WiFi
WiFi and Bluetooth wireless technologies consume a lot of battery power. When not in use, we recommend you turn them off to conserve power and increase the battery life on your laptop. You can also use wired connections, such as Ethernet cables, a mouse, and a keyboard.
Open the notifications on the taskbar and switch on Airplane mode to turn them off.
Or
Disable WiFi and Bluetooth separately from the notifications icon.

Disable UI animations and shadows
Animations and shadows have no significant purpose other than to make your laptop look cool. We recommend disabling them to improve battery health.
Open the Run dialog box (Windows key + R)
Then type “sysdm.cpl” (without the quotes) and hit Enter to open System Properties.
Navigate to the Advanced tab, and then click on the Settings button under the performance section.
Under the Visual Effects tab, select Adjust for best performance and click OK to disable all animations and shadows.

Sync data less
Constantly syncing email, calendars, and contacts often consume a lot of battery power. Syncing email less is a good tip to improve your battery health.
Open Settings
Click on Accounts
Then click on Email & App Accounts on the left pane
On the right pane, select an email account and click on Manage. Then, select “change mailbox sync settings” and choose a longer syncing schedule.
Also, you can turn off auto sync for most Microsoft apps.
Open Settings
Click on Accounts
Click on Sync your Settings on the left pane
Then, toggle off the sync settings option on the right pane

Check power configuration
Using the Windows Command Prompt, you can check which apps and processes consume lots of battery power.
Open the Start menu and search for “cmd” in the search bar
Then choose the Run as Administrator option in the right pane
Here, type in the command “powercfg /energy” and press Enter. The laptop will monitor your usage for 60 seconds.
Then, it will generate a report containing errors, warnings, and other information and store it in HTML. The location of the file is usually provided at the end.
Go to that location and click on the file to open it in your web browser
The generated report will provide details about your laptop’s battery and offer customized tips to save your laptop’s battery life.

Prevent overheating
Heat causes faster battery drain and degradation of the battery. Overheating also causes your laptop to slow down in an attempt to reduce operating temperatures. You should always pay attention to your laptop overheating to avoid causing damage to your battery.

Try Edge Browser
Microsoft famously claimed that their Edge browser uses less battery power, allowing your laptop battery to run up to 36% to 53% longer than other browsers.
