How to Fix Samsung Galaxy S9 Battery Life Issues

Problem 1: Disable Live Wallpapers

Since the Galaxy S9 has a beautiful 18:9 screen, live wallpapers look really good on them. While they might look good to many users, they indeed use a lot of your device’s battery. Not only do these wallpapers use your phone’s screen actively because of the animations, they also use your phone’s processor for rendering the live wallpaper. And as the Galaxy S9 has an OLED panel for its screen, switching to a black static can be highly useful for improving your battery life.

This will save your battery as now you are not using the processor for your wallpaper. Apart from that, OLED screens simply turn off all the black sections on the screen which means that a black wallpaper will turn off most parts of the display, extending your phone’s battery life even further. You can replace the live wallpaper on your device with a black one by following the given instructions.

Solution:

  • Go to the home screen of your Samsung Galaxy S9 and long tap on an empty area.
  • Now head to the ‘Wallpapers’ option and select the ‘From Gallery’ option and choose any black wallpaper.
  • After this, it will ask whether you want the wallpaper for either or both the home screen and the lock screen. Once you have selected that, your Galaxy S9 will then have a static black wallpaper that consumes less battery.

Problem 2: Toggle GPS Modes to Save Battery

Global Positioning System or GPS is a must-have feature in modern smartphones as it makes your life very simple. It is needed in tasks like navigation, auto-filling your approximate location in websites and app, tracking your phone, etc. Unfortunately, GPS also consumes a lot of your device’s battery since it is constantly updating your current location. Thankfully, Google provides the option to change the GPS mode in all android phones which can be used to get more out of the battery of your device.

There are mainly two types of GPS modes, ‘High Accuracy’ and ‘Battery Saving’. And as the name says, the high accuracy mode is useful when you are using applications like Google Maps in which knowing your pinpoint location is highly important. On the other hand, the battery saving mode can be useful for apps and websites that only need your approximate location. Therefore, switching to the battery saving GPS mode when not navigating, means that you will be saving a lot of battery life in the background. You can switch the GPS modes on your Samsung Galaxy S9 via the following steps.

Solution:

  • Open the ‘Settings’ app on your S9 and head to ‘Connections’.
  • After this, open ‘Location’ settings and select ‘Location Method’.
  • You can now simply change the GPS mode according to your needs, that is; if you want to save battery, select battery saving and as long as you do not want to use navigation, everything will be fine.

Problem 3: Change the Resolution to FHD+

The Samsung Galaxy S9, as well as the S9 Plus, comes with a QHD+ display. Even though this display is best in its class and looks very crisp, it consumes a lot of battery because of the high resolution. In simple terms;the higher the resolution your processor has to render, the more battery it is going to consume.

Fortunately, Samsung has thoughtfully added an option on their phones that allows the user to change the phone’s resolution that can further help in increasing the battery life of your device. The best part about this feature is that; it is quite easy to use and you can quickly change the resolution of your device on the go. It is very easy to change the resolution on your Galaxy device by using the given steps.

Solution:

  • Head to the ‘Settings’ app on your phone, and open the ‘Display’ section here.
  • Now open the ‘Screen Resolution’ settings using which you can easily adjust the resolution of your device.
  • You can change the resolution according to your preference between the battery life and clarity of your phone’s screen.

Problem 4: Turn Off Always on Display

Samsung’s Galaxy S9 has an OLED screen due to which they have added the option for ‘Always on Display’ that works pretty well. Since OLED displays can turn on selected areas of a display, always on display allows you to check things like time, date, notifications, weather etc. on your phone, without unlocking it. And the best part about this feature is that it consumes almost no battery due to the display technology.

While the always on display feature also turns on the low power mode, some users have reported that disabling the AoD feature has shown some improvements in their battery. Therefore, you can also try disabling this feature and see if there’s any difference on your phone by following the given instructions.

Solution:

  • Open to the ‘Settings’ app on your phone, and proceed to the ‘Lock Screen’ section in here.
  • After that, you have to find the ‘Always on Display’ toggle in here.
  • You can then easily turn off always on display on your Samsung Galaxy S9 or the S9 Plus using this option.

Problem 5: Optimizing and Removing Apps

Apps that are installed on your phone make up for a huge part in the total battery consumption of your device. So, if you have any extra apps installed on your device that you do not use, make sure to uninstall them right away as many of them keep running in the background. Due to this, your processor is constantly running and your battery gets to zero much faster. Therefore, make sure to uninstall any obsolete apps on your device by holding the app icons and dragging them to the uninstall option.

Solution: After uninstalling any extra apps, we can further optimize the apps installed on your device that you use regularly. For this, Samsung has provided an option for Device Maintenance within the settings app. You can use that to optimize the whole device that will free up the RAM, clear the cache and much more! Overall, optimizing will be an extra bonus for your phone’s battery life.

Problem 6: Enable and Configure Battery Saver

Solution: At last, we have the in-built battery saver mode in the Samsung Galaxy S9 and S9 Plus. You can find the Battery Saver mode in the Battery settings of your phone where you will also see two modes, ‘Mid’ and ‘Max’. These battery saver modes change different aspects of your phone like resolution, animations, processor speed, brightness and much more to bump the battery life of your Samsung flagship device.

 

Conclusion

 Since there are a lot of factors that affect the battery life of your Samsung Galaxy S9, there is a chance that the fixes mentioned above might not have fixed your problems. If that is exactly what you are experiencing with your device, you should either factory reset your device or contact the nearest Samsung service center as Samsung’s trained professionals will surely fix all the issues on your Galaxy S9 or the S9 Plus.
