Thankfully, fixing the Samsung Galaxy A71’s battery drain issue is straightforward. After all, your phone has a built-in battery optimization tool that lets you identify and target the culprits behind the device’s unusually rapid power loss.

As such, you won’t have to worry about performing complicated steps using this solution. 

With a few clicks, your Galaxy A71 can eliminate the root causes of the battery drain problem and stop them from causing further issues. It involves force-stopping background activities, closing problematic apps, scanning for malware, and more. 

Your phone will also list the most power-hungry apps, letting you put them into deep sleep and restrict their background activities until you reopen them.

Once you place an app into deep sleep, it won’t perform any background tasks. Doing so will significantly reduce your Galaxy A71’s overall power consumption and fix its battery-draining problem.

Step 1: Go to Settings.

Step 2: Open “Battery and device care.”

Step 3: Click the Fix Now or Optimize Now button.

Step 4: Click “Show apps causing issues.”

Step 5: Select any app/s.

Step 6: Click Deep Sleep to restrict the background
activities of the chosen app/s.


Note: Deep sleeping apps can’t send notifications and
receive updates until you reopen them.

While optimizing your phone and deep-sleeping its problematic apps helps against the Galaxy A71’s battery drain issue, it also turns these apps useless. 

Since deep sleeping apps can’t run in the background, they fill your phone’s storage for no reason. Thus, it would be better to consider putting them into regular sleep so their background activities are limited but not restricted. 

This way, you can lower their power consumption by reducing their tasks while ensuring you have a reason to keep them on your phone.

Otherwise, it’s better to uninstall your deep sleeping apps since they’re useless anyway. Doing so frees up space in your Samsung Galaxy A71’s internal storage, which you can reserve for more practical and power-efficient apps.

Step 1: Go to Settings.

Step 2: Open “Battery and device care.”

Step 3: Go to Battery.

Step 4: Go to “Background usage limits.”

 
Step 5: Turn on “Put unused apps to sleep.”

Step 6: Go to “Sleeping apps.”

Step 7: Click the plus (+) sign to add apps.

Step 8: Select any app/s.

Step 9: Click Add to put the app/s to sleep.


Note: Sleeping apps will continue sending notifications
but have limited background activity.

FIX 3. Change your Galaxy A71’s display settings

Unsurprisingly, your Samsung phone’s screen contributes the most to its power consumption. It’s understandable since the display screen is active most of the time your Galaxy A71 is in use, regardless of the running tasks and apps.

Therefore, configuring the display settings should significantly fix your Galaxy smartphone battery drain issue. Below are different display settings you can change on your Samsung phone to reduce power consumption.

One way to fix your Galaxy A71’s battery drain problem is to reduce screen timeout. This display setting determines how long your Samsung phone takes to shut down its screen when it’s not in use.

Thus, reducing the screen timeout will make your idle Galaxy A71 turn off its screen faster. Consequently, this will lower the overall power consumption since it cuts the time your phone’s screen remains active.

Step 1: Go to Settings.

Step 2: Go to Display.

Step 3: Select Screen Timeout.

Step 4: Select 15 seconds.

Step 5: Go back to apply the selected
screen timeout setting.

Lowering your phone screen’s brightness level to reduce power consumption is a no-brainer. After all, LCD screens are akin to light bulbs since their power consumption is relative to their brightness.

It’s why even if you don’t change other display settings on your phone, lowering the screen’s brightness level will significantly lengthen its battery life.

Step 1: Go to Settings.

Step 2: Go to Display.

Step 3: Decrease your Galaxy A71’s
brightness level.

Like other display settings, your phone’s screen resolution affects how much power it draws from the battery. Thus, switching to a lower screen resolution is another way to stop your Galaxy A71’s battery from draining fast.

This method works because lower screen resolutions produce images with fewer pixel counts. It means your phone doesn’t have to process as many pixels on its display screen.

Step 1: Go to Settings.

Step 2: Go to Display.

Step 3: Select Screen Resolution.

Step 4: Select HD+ to use less power and click
Apply to set this screen resolution.

FIX 4. Turn off unnecessary display features

Aside from your phone’s display settings, Samsung offers features that change how the screen behaves. For instance, the Edge Lighting feature transforms the screen into a notification light.

While features like this are handy, they consume extra power and contribute to your Galaxy A71’s battery draining faster. Unless keeping these features on is necessary, we suggest turning them off to extend your phone’s battery life.

The Always On Display (AOD) feature on Samsung phones lets you display basic information on the screen even when it’s off. Surprisingly, it helps you save power since you don’t need to turn your Galaxy A71’s screen whenever you want to check the time.

However, AOD still consumes power, regardless of how little that may be. Above all, when trying to stop your Galaxy A71’s battery from draining quickly, you want to save as much power as possible.

Step 1: Go to Settings.

Step 2: Select Lock Screen.

Step 3: Turn off AOD.

Thus, turning this feature off is better to fix your Samsung smartphone battery drain issue.

Step 1: Go to Settings.

Step 2: Go to Notifications.

Turning on your phone’s mobile data consumes power as long as it’s active. However, the more significant issue is that it draws more power when you’re somewhere with a terrible signal reception.

In such cases, your phone constantly scans for a better signal to improve your connection. As such, we recommend turning off mobile data connection under these circumstances to avoid draining your Galaxy A71’s battery fast.

Nearby Device Scanning (NDS) is also an unnecessary feature you should consider turning off unless you need to keep it active. This feature makes your phone scan for nearby compatible devices it can connect with.

Since it happens passively, it adds to your Galaxy A71’s power consumption. In most situations, you should turn this feature off unless you need it for connecting with your nearby Galaxy Buds or Galaxy Watch.

Doing so should help fix your Galaxy A71’s battery drain issue since it will reduce power consumption with one less active feature.

Step 1: Go to Settings.

Step 2: Go to Connections.

Step 3: Go to More Connection Settings.

Step 4: Turn off Nearby Device Scanning.

Of all the solutions in this guide, enabling the power-saving mode is the most straightforward way to fix your Galaxy A71’s battery drain problem. As the name suggests, this mode will reduce your phone’s overall consumption to save power.

It means some features on your Samsung Galaxy A71 will be limited or restricted. This way, only necessary features will continue working in the background, significantly reducing your phone’s battery use.

Unsurprisingly, power-saving mode is also the best way to care for your phone’s battery and keep it healthy. After all, you don’t put your phone’s battery under stress while the power-saving mode is active, which is how you extend its battery’s lifespan.

Step 1: Pull your Galaxy A51’s
notification bar.

Step 2: Pull the notification bar
again to expand it.

Allowing your Samsung phone to overheat due to running multiple tasks or graphics-heavy apps harms its battery. It will make your Android phone’s battery drain faster and cause damage that can shorten its lifespan and lower its capacity.

It would be best to operate your Samsung phone when its temperature is between 32°F to 95°F (0°C to 35°C). Temperature levels outside the recommended range can damage the battery and cause it to drain faster.

If your Galaxy A71 is starting to overheat, you must let it cool down first before using it again. Shutting it down, placing it in front of an electric fan, or storing it in a well-ventilated room will help dissipate heat faster.
