Do you notice sudden battery drain on your Android phone? Chances are that Bluetooth is the main culprit here. Even with your Android phone’s high battery capacity and battery optimization tricks, you will have little to no battery percentage in the morning. Here are the ways to fix Bluetooth drain battery on Android.
First, we’ll show you how to check which apps and services are responsible for your Android phone’s battery draining, then talk about the troubleshooting steps to fix the problem.
Check Bluetooth battery drain
Your Android phone comes with a dedicated battery menu for details. Here is how you can use it and confirm Bluetooth issue on your phone.
Step 1: Swipe down from the home screen and tap the Settings gear at the top. You can also open the Settings app on your Android.
2nd step: In the Settings menu, scroll down to the Battery and device care menu.
Step 3: Tap the Battery menu and select the Battery table from the next menu.
Step 4: You may notice that Bluetooth is at the top of the battery usage list.
Once you figure out that Bluetooth is the main reason for battery drain, follow the steps below to fix the problem.
To note: In the troubleshooting steps below, we will be using the Samsung Galaxy phone running One UI 4.1 (in addition to Android 12 software). The steps and the Settings menu may differ slightly on your Android phone.
1. Stop Bluetooth scan on your Android phone
When you turn on Bluetooth on your Android phone, the system can keep the scanning process running in the background all the time. This can lead to battery issues on your phone. You can stop the Bluetooth scanning process if you don’t need it.
Step 1: Open the Settings app on your Android (refer to the steps above). Select Connections or the Bluetooth menu.
2nd step: Tap Bluetooth in the next menu.
Step 3: Tap the Stop button at the top to halt the Bluetooth scanning process. The option may be slightly different on your Android, but the idea is to prevent Bluetooth from constantly scanning for new devices.
This action stops the scanning process and will not disable Bluetooth functionality.
2. Make sure you keep connected devices within reach
Is your Android connected to multiple devices? You need to make sure that all connected devices are within range and not too far away. Your phone will constantly try to establish a Bluetooth connection and will consume more battery.
If you kept the Bluetooth speaker or other connected devices in another room (separated by a thick wall), you should place them near your phone for best performance.
3. Reset Network Settings
Improper network settings can cause Bluetooth battery drain on your Android phone. Instead of trying to find the right setting change, you can reset network settings and fix the problem once and for all.
Step 1: Open Settings on your Android phone.
2nd step: Use the search bar at the top, type Reset network settings and select it from the search results. It may be available under the Reset Phone or Factory Reset option in the Settings app.
Step 3: Tap Reset Network Settings.
This will reset all network settings – Wi-Fi, mobile data and Bluetooth. Wait for the reset to complete and your phone will reboot.
4. Turn off Bluetooth after use
Most users just keep the Bluetooth service running in the background, even when other devices aren’t connected. After use, you must turn off Bluetooth on your phone.
Swipe down from the top and turn off Bluetooth in the quick toggle menu. You can also open the settings and access the Connections menu. Turn off the Bluetooth toggle and you’re good to go.
5. Allow location services only when the app is in use
Location services on your Android phone can use Bluetooth to get your approximate location. When an app abuses location permission in the background, you may notice high battery usage. Android offers a privacy add-on to limit location permission only when the app is in use.
Step 1: Open Settings and scroll down to Location.
2nd step: Check which apps can access the device location at any time.
Step 3: Tap the app name and select the radio button next to the “Allow only when using app” option.
In the same menu, you can disable the precise location toggle (if not required). Although you should keep precise location enabled for maps, transport and food ordering apps.
6. Update system software
Sometimes a buggy security patch or OS update may have messed up the Bluetooth functionality on your Android. Although this seems highly unlikely for stable releases, it is a possibility if you are using alpha or beta releases. You may be delaying the installation of a minor update that may have the hotfix for the problem.
Open your phone’s settings and scroll down to the Software updates menu. Download and install the latest OS update and check the battery usage menu after a few days.
Keep Bluetooth usage under control
Bluetooth taking up a large chunk of battery life on an Android phone is not a normal occurrence. Instead of being connected to the power supply, use the above tips and fix the Bluetooth battery drain issue in no time.
