How To Fix Samsung Galaxy A9 Battery Drains Fast
Problem: Over the last 2 days, my Samsung A9 has been draining the battery tremendously without any particularly reason. Last night, went to sleep with 45% on a charge, but in the middle of the night it fell to 0%. I didn’t use it and it didn’t seem to charge well at all with the Samsung charger. When it charged till 10% and I turned it out, it fell down to 0% in less than 1 min. Today, the same thing happened. I had about 75% left on my phone and didn’t use. Next thing I used to check a couple of emails, it dropped to 44% and then auto-shutdown showing it is completely flat out. It wouldn’t charge as per night before and it could only manage a 11% in 6 hours. I read in some platform, did all the power savings things, even did a wipe cache, deleted all bloatware, minimized app, and saw the battery was drained by cell standby. Correspondingly when charging, I noted that the phone got really hot. My android is version 89.0.0. I really need some advice if this means my phone is defective or is there anything I can do? I can’t risk going out on a full batt and it turns flat within a few minutes of use. Thank you for all the advice ahead!
Solution: Before performing any troubleshooting steps on this phone it’s best to make sure that it is running on the latest software version first. If an update is available then I suggest that you download and install it first.
Perform a soft reset
If your phone has a lot of services running then it will use up more battery life. Try doing a soft reset then check if the issue still occurs.
- Hold the Power button for 3-5 seconds.
- Tap Power off.
- When the device has shut down completely, wait approximately one minute. This will help make sure that the cache and temporary files are wiped from the device.
Once the phone has started try to check if the issue still occurs.
Start the phone in Safe Mode
It’s very likely that an app you downloaded is causing this particular problem. The best way to check if this is the case is to start the phone in Safe Mode since only the pre-installed apps are allowed to run in this mode.
- Turn the phone Off
- Press and hold “Power”
- At the “Samsung” logo, release “Power” and immediately press and hold “Volume down”
- After the phone finishes rebooting, release the keys. A “Safe Mode” watermark should be visible in the lower area of the home screen
If you don’t experience the battery drain issue in this mode then it could be caused by an app you downloaded. Find out what app this is and uninstall it.
Wipe the cache partition of the phone
The phone will usually store cached data of apps in a special partition of its internal storage. This cached data allows the phone to open apps quickly making for a better mobile experience however there are instances when the saved data can become corrupted which can cause issues on the device. To eliminate this factor you will need to wipe the cache partition of the phone.
- Turn the phone Off if necessary
- Press and hold “Power” “Volume down” and “Home”/”Bixby” at the same time
- At the Android screen, release the buttons and wait for access to Android Recovery
- Press “Volume down” to navigate the menu to highlight “Wipe cache partition”
- Press “Power” to select the highlight
- Finally, highlight “Reboot system now” and press “Power”
Check if the issue still occurs.
Perform a factory reset
One last troubleshooting step that you should consider doing is a factory reset. This reverts your phone to its original factory condition. Make sure to backup your phone data before doing this step as it will be deleted in the process.
- Turn off the phone.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
- Press the Volume down key several times to highlight ‘wipe data / factory reset’.
- Press Power button to select.
- Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
- Press Power button to select and start the master reset.
- When the master reset is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
Once the reset is complete do not install any apps in your phone yet. Try to check first if the issue still occurs. In case is does then this is most likely caused by a faulty hardware component. You will have to bring the phone to a service center and have it checked,
