For screens with large sizes, this is one of the factors that causes rapid battery drainage. Therefore, adjusting the screen is the first step you need to pay special attention to if you want to save battery for your Samsung A8.

To start, instead of allowing your phone to automatically adjust brightness, take control manually. Set it by accessing Settings => Display and choose around 40-50% brightness as optimal. Then, customize screen timeout to 30s.

2. Identify Battery-Draining Apps

In reality, some heavy apps might be the primary cause of battery drain. Hence, remove unnecessary apps by navigating to Settings => Applications => Applications manager and review all installed apps. Then, tap Uninstall to remove unused apps.

3. Utilize Battery Saver Mode

Currently, certain Samsung devices come with a battery-saving feature, minimizing energy consumption and providing extended usage time.

To set up, access Settings => Battery. Then, choose between two modes: Power Saving and Ultra Power Saving according to your preference.

4. Disable Unnecessary Connections

Using Wi-Fi or 3G connection gradually drains your battery. Therefore, when not using the internet, turn off these connections.

To do this, simply swipe the screen to access Quick Settings. Then, touch to turn off Wi-Fi and 3G in a moment.

Above are the methods to increase battery life on Galaxy A8, making your Samsung A8 last longer. In addition to the above methods, you can choose the top 5 battery-saving apps for Android to get the device with the highest battery life.
