No matter what kind of phablet you have, squeezing out every last drop of battery life is a constant struggle. The Samsung Galaxy S8+ is equipped with a 3,500 mAh battery, which is smaller than the 3,600 mAh battery in the Galaxy S7 Edge. The Galaxy S8 features a 3,000 mAh battery, which is the same capacity as the regular Galaxy S7.
Odds are that either Galaxy S8 device will get you through a busy day with some juice to spare, but you might be wondering what can be done if you’d like to get even more time between charges. Below, we’ve compiled a number of tricks and tips that will improve the battery life on Samsung’s latest flagship.
Some of these battery saving tips will be obvious to just about any Android user, while others require a little bit of digging. Of course, nobody is suggesting you use all of them, but you should test them all out and decide what works best depending on your situation.
With that said, let’s look at some of the easiest and most effective ways to improve your Galaxy S8 / S8 Plus battery life!

1. Use a dark color scheme for more on screen time
Opting for a darker color scheme with your Samsung phone is a simple and efficient power saving trick. Due to the way Samsung’s Super AMOLED displays are designed, the color white requires the most out of the screen in terms of power draw, so going for a black or darker color theme will save you a decent amount of power.
You can change your theme by going to Settings -> Wallpapers and themes.

2. Turn down the automatic brightness
The huge display found on the Samsung Galaxy S8 is among the most power-hungry components inside the device, so you should tweak the automatic brightness setting to keep it in check. Your phone will still adapt to your surroundings, but keeping a slightly lower max brightness will help you save some precious battery juice.
Lower the max brightness by navigating to Settings > Display > Auto Brightness.
You can also adjust the brightness by pulling down the notification shade and adjust the slider. Moving the slider to the left will lower the brightness, moving the slider to the right will increase the brightness. If you hit the arrow to the right of the slider, a menu will drop down so you can toggle auto brightness on or off by click on the box to the right.
3. Ditch the Always On Display
Glancing at your phone as it sits on your desk to check the time or notifications is nice, but it’s also makes your battery bleed a slow death. Moreover, when you’re looking for increased battery life, every little bit helps, which is why it makes more sense to simply light up your screen when you need to check something out.
With Always-On Display (AOD) turned off, your phone’s screen will remain off while it is locked. On the plus side, you’ll be more productive if there isn’t a constant distraction sitting in front of you.
Disable Samsung’s Always-On Display by opening Settings > Lock screen and security > Always On Display.
4. Put apps to sleep with the App power monitor
The app power monitor is a great feature present on your Galaxy S8/S8+ that helps you save power by putting apps running in the background to sleep if they’re not used for 3 days. Samsung also added the option to manually put apps to sleep.
When an app is “sleeping,” it won’t run in the background, and any push notifications to the app will be paused. The next time you open the app, it will wake up, with notifications and updates returning to normal.
Sleep apps by going to Settings -> Device maintenance -> Battery. You can also long-press on an app icon until a settings popup is shown. Select Sleep from the list, and then tap OK.
5. Minimize battery drain while gaming with Game Launcher
Game Launcher was first introduced with the Galaxy S7 duo. This nifty little app can help you save battery life by reducing the screen resolution and frame rate when playing mobile games.
Of course, tweaking your screen settings will result in a slightly degraded gaming experience, so it may not be for everyone. Nevertheless, if you are in a pinch and just have to get your Pokémon Go fix in, this may be a trick to keep in the bag.
You can find Game Launcher in the Apps Drawer. You can adjust power saving options by tapping on “Save power during game.”
Bonus Tip: Game Tuner is a Samsung app that isn’t installed with your S8 by default but you can download it free at Google Play. This application also lets you tweak the performance settings of mobile games that require tuning for different Android devices.
6. Turn off “Smart Stay”
Smart Stay is an interesting feature that uses the Galaxy S8 selfie cam to figure out if you’re looking at the phone’s display. Your screen won’t go to sleep as long as you’re looking at it, which can be very useful if you like to read e-books or just stare at your phone.
While this feature is undoubtedly handy, your selfie camera and the Smart Stay app both consume battery and processing power. Therefore, if you want to maximize your daytime phone usage, it might be a good idea to turn Smart Stay off.
Disable this battery killer by navigating to Settings -> Advanced Features -> Smart Stay.
7. Set a quicker screen timeout for more power gains
All of us probably used to turning the phone screen off when we are done using it, which is why it makes no sense to set a long timeout period for your display. Setting your timeout to 30 seconds or a minute should be plenty in case you forget.
The Galaxy S8 has a default screen timeout of 15 seconds, giving you the most battery saving potential. We recommend you leave it there or, if you must, bump it up to 30 seconds. Any longer than that and you’ll be wasting your battery.
Customize this feature by going to Settings -> Display -> Screen timeout.
Setting the timeout to a minute or less should be more than enough for most people’s needs, while ensuring that the display won’t stay turned on for too long while not in use.
8. Set a lower screen resolution for everyday use
We already discussed how adjusting your screen resolution could save battery power when gaming, but what about adjusting the resolution for everyday tasks? Well, there are three other display resolution options available on Galaxy S8 duo – HD+ (1480 x 720) FHD+ (2220 x 1080), WQHD+ (2960 x 1440).
You can switch between these options by going to Settings -> Display -> Screen resolution.
Here, things are simple – lower resolution translates to lower power consumption and vice versa. Do you really need super high-res WQHD+ resolution for sending Facebook messages? Probably not, but you will definitely need it when watching Netflix and YouTube. The trick here is balance.
Out of the box, the Galaxy S8’s screen resolution is set to full high-definition but you can probably get away with leaving the display set to FHD for everyday use. Then you can step it up to high-performance mode when you’re playing games or binge-watching your favorite TV show.
You can switch back to a more efficient mode at any time by using the same method to turn off high-performance mode. Using HD+ mode will certainly help if you find yourself in a pinch when you need to get the most out of your battery.
Bonus Tip: There is a dedicated tile to boost the Galaxy S8 performance in the quick settings menu.
9. Turn off NFC to save power
Unless you are going on a shopping spree or transferring data through NFC, there’s really no reason to keep it on all of the time. The overall drain on your battery from this radio is negligible, but it’s important to remember that all of these little tweaks result in big savings overall.
Use the dedicated toggle for NFC in your notification shade/pull down menu. You can also turn it off by heading over to Settings -> Connections.
10. Turn off the LED indicator
The LED indicator is that little light that blinks when you have unread notifications, turning it off will give your battery a tiny boost. More importantly, however, you will be eliminating a huge distraction from your day by not grabbing your phone every time an app sends you a notification.
Kill this nuisance by heading over to Settings -> Display -> LED indicator. You might even get more sleep at night.
11. Avoid butt-dials with Keep screen turned off
This setting should be enabled by default on your Galaxy S8 / S8+, but you might want to double check just to be sure. Keep screen turned off is a neat feature that lets your Samsung device recognize when it’s inside a pocket or bag, and shouldn’t be turning on if a button is accidentally pressed.
While this feature will consume processing power, it will save you from butt-dialing people and have a net positive effect on battery savings. You can check if it’s turned on by navigating to Settings- > Display -> Keep screen turned off.
12. Turn Off “Nearby device scanning”
There is a feature in the Galaxy S8 / S8+ called “Nearby device scanning” that makes it easier for your phone to find Bluetooth devices by constantly scanning for them, even if you have Bluetooth turned off. The feature uses Bluetooth Low Energy to make the connection process easier when you actually want to hook up to something, but unfortunately, it has a negative on the phone’s battery life.
Needless to say, unless you are having problems connecting to Bluetooth accessories, you can live your life to the fullest without using this feature, so make sure to turn it off by going to Settings -> Connections -> More connection settings.
13. Switch to the GPS only location method
It seems like just about every app these days want access to your location, which is not only harmful to your battery but also incredibly creepy. Knowing your precise location is obviously a great thing to have in certain situations but remember that your handset uses a lot of processing power to pinpoint where you are.
Luckily for you, there is a way of saving some battery juice with location turned on by switching to a GPS only mode. You phone will use less power this way because it won’t utilize your WiFi and Mobile Network hardware to get the job done.
You can switch to a GPS only mode by going to Settings -> Connections -> Location -> Locating method and switching to Phone only.
14. Disable Wi-Fi and Bluetooth scanning
While we are on the topic of the Location tab, make sure to tap on Improve accuracy and shut down Wi-Fi and Bluetooth scanning. These options are designed to improve the accuracy of your phone’s location services, but as mentioned above, your precise whereabouts are usually not that essential for most apps.
15. Ditch the useless Gestures
Even though Samsung has eliminated the number of “gestures” over the last few years, you can still find plenty of them on the Galaxy S8 duo. What you choose to go with here is completely personal preference, but pick them wisely because each one is a leech on your battery.
Customize your phone gestures in Settings -> Advanced Features. Options here include: Smart capture, Palm swipe to capture, Direct call, Smart alert, Easy mute, Swipe to call or send messages, and Direct share.
16. Enable Power saving mode
If you’ve been web browsing all day and watching YouTube videos, chances are your battery will be running low by the late afternoon. This is where Power saving mode comes in.
Power saving mode halts some processes that may eat away at your battery. Your apps will stop fetching new data in the background, location services will be turned off, and even vibrations will be kept to a minimum.
There are a few caveats here. When power saving mode is enabled on the Galaxy S8, for example, emails or notifications won’t come through unless you are using the associated app. Texts and calls, however, will remain unaffected.
Access the power saving mode by navigating to Settings > Device Maintenance > Battery, or find it in the quick settings (drag down from the top of the screen with two fingers to see all options). You can choose to manually enable it, or have it activate when you batter percentage reaches a predefined level.
The power-saving setting gives you the option to choose predefined settings, or you can manually pick how aggressive you want the power saving to be by tweaking the brightness, screen resolution, CPU speed and network usage. You potential battery savings are displayed underneath each option.
If the normal power saving mode isn’t strong enough, MAX POWER SAVING MODE is your last resort. This power saving mode will squeeze the maximum life out of your device by switching the display to low resolution black-and-white, and all applications are disabled except for Phone, Messages and Internet.
17. Use a Power Bank
When the aforementioned software tweaks aren’t enough, one of the easiest ways to extend your Galaxy S8 battery life is to simply recharge on the go whenever you can. You should consider picking up a power bank or portable charger in the size, shape and capacity that best suits you.
Keeping a wireless charger at your desk, in the kitchen, or by the bed is the most convenient way to keep your phone topped off throughout the day. We recommend one of Samsung’s Adaptive Fast Chargers, as these will allow you to recharge much faster than with a traditional power bank.
18. Use a Battery Case
Another great accessory to consider is a protective phone case with a battery pack built-in, which allows you to increase your battery capacity with ease. Cases with built-in batteries stay connected to your phone – and they recharge at the same time as your phone – just keep in mind that these cases add to the size and weight of the phone, along with an added measure of protection.
