Out of all the things that we value in our smartphone, the battery usually takes the top position. So if you are trying to find out how to fix Samsung A8 battery life issues, then we have some solutions that can help you enjoy your Samsung device without worrying about its battery. The A8 has a 3050 mAh battery which is good enough for the average user, but if you have too many apps running in the background or if you are a power user, then you may notice that the battery does not last long enough. At times, the battery may be physically damaged which may be causing the problem as well. Use these solutions to fix battery life issues on your Samsung A8 phone.

Potential Fixes For Samsung A8 Battery Life Issues

Solution 1: Check our battery usage

A great place to begin looking for the reasons why your phone’s battery is discharging quickly is to check the battery usage.

Go to the Settings menu of your phone
Tap on Battery
Next tap on Battery Usage

Now you will find the apps that are using up your phone’s battery. Usually, the screen takes up most of your battery and if you are using a particular app a lot, it will inevitably show high up on the list. You must keep an eye out for apps that are using up your battery without your knowledge. If you notice the unexpected use of battery by a certain app, it is best to consider uninstalling that app or look for updates for the app and check if it’s battery-eating behavior changes. If not, then uninstall it.

On the other hand, if all the apps are working as expected, then try reducing the amount of battery used by the screen by bringing down the brightness of your A8’s screen. If you use automatic brightness, consider switching it off and manually set the brightness level to something that is comfortable for your eyes. You can also update the screen timeout to choose the lower time before your screen switches off.

Solution 2: Tweak the phone settings

Other settings on your phone which may impact battery life is GPS, Bluetooth, Wi-Fi, connectivity and the sync settings. Power users usually end up draining the battery quickly because of incessant use of different apps and lots of apps that run in the background. If you are not using the location services and you are not connected to another device using Bluetooth, then consider switching them off till you need them. The same thing applies to the Wi-Fi. If you are not connected via Wi-Fi then switch it off, or else your phone will try searching for Wi-Fi if you are on the move. This can take up valuable battery life.

Pull down the notifications shade of your Samsung A8 and check for services that are switched on which you are not using. Tap on the icons to switch off the services like GPS, Bluetooth and Wi-Fi if they are not in use. This will help you improve your Samsung A8 battery life.

In addition to these settings, check the sync settings of your device and find out if your Samsung A8 battery draining problem is because of too much syncing in the background. App sync makes your device work even when the screen is off so that it can look for new notifications. Switch off app sync for apps that are not as necessary. When you access the app, it will automatically update your notifications so you can check new notifications by accessing the app anyways. Limit syncing to priority apps like emails only to improve your Samsung A8 battery life.

Solution 3: Power Saving Mode

The power saving mode can be an effective method of boosting your phone’s battery life. While it may not be extremely helpful, until you use Ultra Power Savings mode, the Samsung A8 battery life issues can be fixed to a certain extent with the help of Power Saving Mode. While using this mode, your phone will limit background services and it also restricts location services. You can set your phone to automatically switch on Power Savings mode when the battery reaches a certain percentage, or you can switch it on manually from the notifications shade of your device.

Go to the Settings menu of your phone
Tap on Power
Tap on Power Saver and then you will see an option that allows you to choose the battery percentage when power saving mode should be switched on.

Tap on the option you want, and switch on power-saving mode.

Solution 4: Update the apps and your phone software

Make sure that all your apps and software programs are updated all the time. Updates help in fixing known issues and current bugs which may be causing a problem for your device. This can include misbehaving apps that drain your phone’s battery. To update the phone’s software, follow these steps:

Go to the Settings menu of your device
Tap on About Device
Tap on Software Updates and allow your phone to check for new updates. It will prompt you to download new updates if there are any.

Download and install the updates to ensure that your phone’s performance is optimized and current issues with the software that may be affecting the battery life are fixed.

To check for updates for the apps installed on your Samsung A8,

Go to the Play Store
Tap on the menu option (three horizontal lines) on the top left of the page.
Tap on My apps and games
It will show you all your installed apps and if any of them needs to be updated, it will give you the option to update it right next to the app. You will also notice an Update All option at the top of the apps.

Click on update all and update the apps so that you can fix any bugs and issues with the apps installed on your device. It will help you improve battery life and optimize the performance of the app.

Solution 5: Calibrate your Samsung A8 Battery

Sometimes, your phone’s battery begins to display unwanted behavior when certain battery data gets corrupted and your phone misinterprets data to switch off before your battery actually drains out. To fix this, you must calibrate the battery of your phone so that the Android OS reads battery information correctly. Follow these steps to calibrate your phone’s battery without root access:

Allow your phone to automatically turn off after the battery is fully discharged.
Switch it on again and allow it to turn it off on its own.
Now connect your Samsung A8 to the charger and let the battery charge to 100% without turning on your phone.
Once the screen shows that the battery is charged 100%, disconnect the charger and switch on your phone. Does the battery show 100%? If not, then connect it to the charger while it is on, and let it reach 100%.
Disconnect the charger and restart your phone. Check if the battery says 100%. If it doesn’t then reconnect the charger and let it charge till it says 100% again.
Continue to do this till your phone shows 100% when it restarts without being connected to a charger.
Use your phone as usual and allow the battery to discharge till your phone turns off.
For the last time, charge the battery completely and your phone’s battery calibration is completed.

You will notice that the battery performance of your device improves after a calibration. However, the entire process can have a detrimental effect on your phone’s battery if you do it too often. So make sure that you use calibration as a one-time solution to fix battery issues.

Solution 6: Use a third party app

Third party apps like Greenify are a boon for power users. These apps help users improve battery life by limiting background apps, sync, location services, Wi-Fi connections and lots more. With the help of this app, you can tweak a number of settings on your phone to reach an acceptable battery life. While Greenify is one of the apps that is regarded to be a successful one, other apps include Battery Drain Analyzer and Battery Saver. Pick an app that has good reviews so that you can fix the Samsung A8 battery life issues effectively.

These are the best ways to fix battery life issues on your Samsung A8 phone. We have kept non-rooted phones in mind while devising these solutions because rooted phones have a lot of other variables that can make a difference in battery behavior. While battery life can be affected by unwanted apps or a bug in the phone’s software, sometimes, overusing the phone by watching lengthy videos and playing games for long hours also affects the battery life over a period of time. If you happen to be using your phone for watching lots of videos or heavy streaming, then be prepared for the battery to last for a shorter period than expected.

However, if your phone is fairly new and you notice battery problems right from the start, then there is a chance that there may be problems with the battery itself. In such cases, if the solutions above do not work, you must take the phone to a repair shop or your carrier.
