Battery life of smartphones depends essentially on how battery life is being drained and different models of devices have different size and system draining of battery life. Commonly the expected battery life for your model can be discovered in the user manual of your Samsung devices. We compile a list of very useful tips to help you get the best and most out of your battery in everyday device consumption.

Here Are Tips On How To Extend Your Samsung Phone’s Battery Life Longer Without Charging Too Often.

1. Find The Apps That Consume Phone’s Battery In the Background.

Draining your phone’s battery life can be a critical factor if there are applications (Apps) that don’t work like how it is supposed to be. This behaviour of apps can be affected by a bug that 

Your battery life can take a big hit if an app doesn’t work like it’s supposed to. This could be caused by anything from a bug to an aggressive operation on the background feature. This aggressive consumption of battery life would usually be recorded by your phone. 

You can identify this by going to Settings > Battery > Menu > Battery Usage (usually the apps drained most will be ranked at top of the list)

Battery life usage 1

If you notice there are apps that you don’t usually use much, then you should uninstall it and keep track of your battery usage again for a day to witness the improvements. Force close the unused apps would also help you get the same battery saving as well. For apps that don’t prove useful, get rid of the apps and use alternative lite apps. You just have to make sure that there are no battery killer apps in your phone to keep your phone’s battery life being drained unnoticeably. 

There are times where you are not going to use some apps that you have installed, therefore you should check which apps you really didn’t use at all and decide to uninstall it to avoid battery draining in the background not noticeably. You can uninstall any unused apps with following methods:

Long press on the App’s Icon > click Uninstall > OK.


Settings > Apps > tap on Apps name > Uninstall > OK. 

App to uninstall 1

If you discovered some apps that couldn’t be uninstalled on some Galaxy Smartphones, then you can ‘Disable apps’  to increase battery life. 

To Disable Apps, go to:

Settings > Apps > tap on Apps name > Disable > Disable app.

2. Turn On Adaptive battery feature:

You can also turn on Adaptive battery to help you limit battery usage for apps that you don’t use that often. You can also put unused apps to sleep when they haven’t been used for a while, which would greatly help your phone save more battery life. You can enable it as follows:

Settings > Battery > App power management > turn on Adaptive battery & Put unused apps to sleep.

3. Limit Background Data Access for Each Apps.

As background data may progressively drain by apps allowed, this is also the factor of battery draining. To avoid from battery draining, you can disable background data usage apps as follows:

Settings > connections> Data usage>  Mobile data usage > Select the Apps > Turn Off “Allow background data usage”.

4. Turn Off Automatic Wi-Fi

After the Android 8 Oreo update on your phone, the feature to continuously search for open Wi-Fi networks is available even when you have disabled Wi-Fi. You would want to avoid the battery being drained by the automatic Wi-Fi option. In order to turn it off, you can do as follows:

Settings > Connections > click Wi-Fi > click 3 dots on the top right corner > Advanced > toggle to disable the “Turn On Wi-Fi automatically” option.

5. Enable Dark Mode

The Super AMOLED screen on Samsung smartphones can produce a very sharp, bright and clear display output. With this OLED technology screen, commonly the colour pixels would consume more battery than black pixel colour, this is why the Dark mode was present to save longer battery life. By enabling dark mode, most common compatible apps will turn to dark mode as well such as Youtube, Gmail, Webpage & more.  

You can enable Dark Mode in the setting as follows:

Settings > Display > First Option is to select ‘Light’ or ‘Dark’ mode.

6. Disable GPS Function If Not in use:

Your phone consumes more battery life from the GPS feature when turned on. However, for some of the apps, we would conveniently want our smartphone to take control of how the apps would use the GPS location only when recommended or necessary.

When you enable the GPS location feature, it will consume more battery life with the setting of “Improved Accuracy” being enabled as well. 

You can disable this feature inside the Settings > Location > Improved Accuracy > to disable “Wi-Fi scanning” and “Bluetooth scanning”. 

Here is an extra tip for you to disable the unnecessary use of GPS location by giving permission for apps that don’t require it at all times. You can set app permissions to use GPS Location as follows:

Settings > Location > App permissions > select the apps you want to >

  • Allow all the time 
  • Allow only while using the app
  • Disable/deny

GPS location allow all the time 1

7. To Lower Phone’s Display Brightness Level

High display brightness and long screen time-out setting will increase battery drain. One of the simplest way to prolong your device battery life is to reduce the screen brightness, and here’s how you can do it:

Setting> Display > adjust the ‘Brightness’ level.

You can also set the brightness with Adaptive brightness, whereby this will help to automatically adjust your screen brightness level based on the current lighting conditions. Example if you are in bright sunlight condition, your display will automatically set to higher brightness so that you can see your screen clearer, thereby it will lower the screen brightness if you are in lowlight or dark environment.

8. To Reduce Screen Timeout Time

The longer your screen timeout, more battery life will be drained if your screen has not turned off at the set duration. You can set your screen to turn off by going to the screen timeout setting. The lowest duration to turn off your screen is 15 seconds. Set you screen timeout duration here:

Settings > Display > Screen timeout > set to lowest duration based on your preference.

Usually I prefer to set the screen timeout to 30 seconds because it will not last too long or will not turn off too fast.

Screen timeout 30s 1

9. Lower Down Display Resolution

Higher resolution setting on your phone definitely looks brighter and clearer with more detailed content. However, you can in fact extend a lot of battery life by lowering the screen resolution as follows:

Settings > Display > Screen Resolution > set to lowest to save more battery life.

10. To Reduce Refresh Rate.

For some Samsung smartphones  that are equipped with a high refresh rate capability screen, you can enjoy a very smooth and fluent screen experience with Adaptive screen setting. To turn off high refresh rate, you can follow guide as below:

Settings > Display > Motion smoothness > Standard.

11. Disable Always On Display or schedule it.

Always On Display or AOD uses Super AMOLED displays to show you certain information such as current time and date when your screen is turned off. This AOD feature allows you to check the basic information easily without turning on the whole display. Technically, when an activity is set to turn on your screen at all times, it will drain some battery life. You can opt to turn off this AOD feature or set a time schedule to turn on/off AOD feature.

To turn off AOD: 

Settings > Lock Screen > Always On Display > turn off by sliding the circle to left. 

To show AOD as schedule:

Settings > Lock Screen > Always On Display > Show as scheduled > set schedule to show AOD. 

Usually many phone users will schedule to show AOD in the evening since you are at home and didn’t wear any smartwatch or watch. However, you can feel free to set any schedule you want if you are not a watch person like me.

12. To Turn off Edge lighting

When you receive a notification, you can use this edge lighting feature to notify you which is very cool looking when you have a curvy display.

Slide down the notification panel > tap on the “Dolby Atmos” to turn off.

18. Check how often you need your device synchronizes data

If you have several apps on your phone that frequently require syncing, to check for new emails or updates, that will reduce your battery time. So you can turn it on when you only need them to, while if you don’t need it kept on syncing, then you can turn it off as follows:

Slide down the notification panel > tap on ‘Sync’ to turn it off.

19. Switch your wallpaper and theme to dark

Since Samsung phone’s display uses AMOLED technology, anything that is a dark or black pixel of the screen consumes less power than other bright colours. This as well helps your phone to avoid battery draining to your wallpaper without notice, so changing you wallpaper is recommended by following the guide here:

Hold down an empty space of your home screen (or) Settings > Wallpaper > My wallpapers.

20. Avoid using Dynamic Lock Screen Wallpaper

This is a great and awesome feature to always get updated with new Lock Screen Wallpaper and would change to different Lock Screen Wallpaper everytime you unlock your phone. This is one of the factors of battery draining issues and you can also disable it as follows:

Settings > Wallpaper > Wallpaper services > Select None to disable Dynamic Lock screen.

21. Disable the Unused App’s Notification 

With the Apps running in the background that would notify you for any reasons, it would drain power from your battery ongoingly. This would increase more battery consumption if there are more Apps you have installed eventually. Therefore, you can turn off the unused App’s notification as follows:

Settings > Notifications > App Notification (tap See All) > Most recent > ALL > toggle slider to left to turn off the Notification of unused Apps.

Settings > Connections > Mobile Network > turn off ‘Data roaming’.
