Galaxy A

Hello there! jb1234,

Thanks for letting us know here your experience with your beloved Samsung Galaxy A72 having issues with overheating and fast-draining battery even switched-off. I feel and understand why you are worried for a device that you've take care so much. If my device is facing similar experience, I will get worried too.

Battery consumption and lifespan varies depending on a number of factors, including the frequency of device use, the number of installed and running apps, operating system errors, and network connectivity. 5G networks may drain the battery faster, but Galaxy phones use advanced AI-based software to efficiently control battery consumption to suit your usage patterns.


Before you try the recommendations below, be sure to check if your device's software and related apps are updated to the latest version. To update your mobile device's software, follow these steps: 

Step 1. Go to Settings > Software update.

Step 2. Tap on Download and install.

Step 3. Follow the on-screen instructions.


Battery can be consumed a little faster right after purchase.

You may notice that your new phone's battery seems to be draining faster compared to your previous device even though you are using it under the same conditions after purchase.

During the first few days after purchase, users have usually activated many applications and set various features for initial device setting, and the frequency of background operation is optimized at this period. So, you may feel the battery usage time is shorter compared to when you were using your previous device.


5G service may consume more battery.

While connected to a 5G network, your phone may consume more battery than usual. Current 5G services are compliant with the Non-Standalone (NSA)* standard, which uses 4G (LTE) and 5G together. Therefore, 5G and 4G (LTE) circuits are used simultaneously for the high-speed processing of large-capacity data.

Since your phone is connected to multiple networks at the same time, the battery may drain faster than you would typically expect, and your phone may get a little warmer than when solely on 3G or LTE. To make up for this, you can use features that will optimize and improve your phone's overall performance. 

* NSA(Non-Standalone): The first roll-out of 5G networks and devices will be brought under Non-Standalone (NSA) operation, which is to say that the 5G networks will be supported by existing 4G infrastructure. Thus, 5G-enabled devices will connect to 5G frequencies for data throughout but will still use 4G for non-data features such as connecting to the base stations and servers.

Note : If you feel the device overheats, do not use it for a while and wait while the device cools. When you are indoors with weak signals or poor reception where the service provider’s base station cannot support or if there are obstacles around, the 5G signal of the device may weaken or switch to a 4G network.


How to optimize your phone battery.

If you want to extend the battery lifespan of your phone or if you feel that the battery is draining fast, you can optimize your phone overall, manage app power as well as optimize individual apps. You can reduce battery consumption in the following ways.


Optimize the overall usage of your phone.

You can optimize your phone using the Device care feature to reduce battery consumption by closing unused apps and controlling abnormal battery usage. Follow the steps below.

Step 1. Open Settings, and then select Battery and device care.

Step 2. Tap Optimize now. Device care automatically optimizes your phone.

The quick optimization feature improves device performance through the following actions.

  • Closes apps running in the background.
  • Manages abnormal battery usage.
  • Scans for crashed apps and malware.

Using the auto optimization feature

You can set the device to perform auto optimization when your device is not in use. Tap More options > Automation > Auto optimize daily and tap the switch to activate it.


Adjust Background usage limits.

The more unused apps there are running in the background, the more power your battery will use. Background usage limits can be set to reduce battery consumption. Follow the steps below.

Step 1. Open Settings, and then select Battery and device care.

Step 2. Tap Battery.

Step 3. Tap Background usage limits.

Step 4. Set the app you want to control.

You can choose from the following settings:

  • Put unused apps to sleep which will automatically put apps to sleep if they have not been used for a while.
  • Sleeping apps allows you to choose the apps that won't run in the background. You can view your current sleeping apps as well.
  • Deep sleeping apps will never run in the background and will only work when you open them.
  • Never sleeping apps allows you to choose which apps will not automatically be set to sleeping mode.


Optimize individual apps.

Step 1. Open Settings, and then select Apps.
Step 2. Tap More options (the three vertical dots).
Step 3. Select Special access.
Step 4. Select Optimize battery usage.
Step 5. Select the app you want to optimize. Optimized apps use less battery.
Note: Optimized apps will use less battery, but some background functions will be restricted.

In order to find out the root cause of the problem, you may submit an error report through the Samsung Members app as follows:


Step 1. Launch the Samsung Members app, and then tap the Support icon for more options.

Step 2. Scroll and select Error reports.

Step 3. Choose a category of your concern. Select "Power/Battery/Charging".

Step 4. Choose the frequency of the issue you are experiencing. Enter issue details or attach a video or screenshot. Then press Send icons to complete the report. 


If the problem persists, immediately bring your device to the nearest Authorized Samsung Service Center. Rest assured that our team of Samsung engineers and technicians are competent to assess your device with suggestions, and offer to provide prompt solutions to restore it up to optimum performance.

Hey there, jb1234! There are a few factors that may be causing your Galaxy A72 to overheat and consume more battery power. Here are some of them and how you can help save your battery life. 🔋

  • Screen brightness and timeout - You might be using your screen a bit too bright. Remember - the brighter your screen is, the heavier it is on your battery. You can go ahead and adjust this in your quick settings panel or in the settings. You can also adjust your screen timeout so it automatically turns off when you're not using it! I'd recommend either 15 seconds or 30 seconds. 😊
  • Unnecessary connectivity features - If you're not using your mobile data, Bluetooth, WiFi, or GPS/location, it's best to turn them off so they don't take up much of your battery life searching for connections or running in the background.
  • Unnecessary background apps - Remove all unnecessary background apps to stop them from running, especially if you don't particularly need them! This helps save your device's RAM and battery life!
  • Power Saving mode - Enabling this can significantly extend your device's battery life! However, this does reduce performance and limits background activities. To do this, simply go to your quick settings panel, look for the Power Saving icon, and tap it to turn it on. You can tap and hold this icon to also know how many minutes or hours your battery has left.
  • Firmware - Always make sure you have the latest firmware update! Updates usually include battery performance updates. You can check for latest updates by going to Settings > Software update.

We want you to have the best phone experience so please let me know if this helps and good luck! 🤗
