How to save battery on your Samsung Galaxy S9 (Battery Saving Tips)

I was told by one of our readers that in order to save battery, you should just turn the phone off and not use it. Funny as it may seem but it’s true that is if you only just want to save battery and not use your phone. But we know that’s not really the essence of saving battery; we want that our phone could last for a few more hours and still continue to use it.

But you know what, to save battery is tantamount to saying to handicap your phone, which means something has to give in. If you’re an owner of the new Samsung Galaxy S9, well, congratulations as you have one of the best and power-efficient smartphones in the market today. So, continue using your phone to its full potential and don’t worry too much about draining its battery quicker, after all it has the quick charge feature so if you’re not mobile and has access to a power source, this article won’t even matter to you.

However, if you are travelling and it would take a few hours before you can have an AC outlet to plug your charger into, then the following tips may help save battery in your phone. It’s better that you know a thing or two because even if you can save 1% of battery, that could give a few more minutes to continue using your device.

How to extend your Galaxy S9 battery


Any of the tips below can help you save battery. Depending on the situation you’re in, you may not have to do all of them. Continue reading to know more about each tip’s benefits and how to do it…

Turn on Galaxy S9 Power Saving Mode

There’s a built-in power saving feature in your phone so when it comes to extending battery life in your new phone, it should be the first thing you should look into. This alone can give you a few more hours of usage and here’s how you turn it on:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Device maintenance > Battery.
  3. Under ‘Power saving mode,’ select MID or MAX.
  4. Each option provides an estimate of remaining battery life.

When this feature is turned on, you can then access its settings which will give you the following option:

  • Turn off background network usage.
  • Turn off Always On Display.
  • Turn on Speed limiter which caps your device’s CPU and GPU usage among other things.
  • Decrease screen brightness.
  • Change screen resolution to a lower value.

You can also access App power monitor which allows you to select apps to stop when you’re not using them. Make sure you hit the Apply button every time you make changes.


Turn off Vibrate Mode or adjust its intensity

This is only applicable if you’re using Vibrate Mode to notify you of messages, calls and other app notifications. To make it easier, it’s better to just place your phone under silent mode instead of having it to vibrate every time notifications pop up. However, if it’s possible for you to do such thing, then you can simply adjust the intensity of the vibration. Remember, the higher the intensity, the more juice is squeezed out of your phone:

    1. From a Home screen, swipe up or down from the center of the display to access the apps screen.
    2. Navigate: Settings > Sounds and vibration.
    3. Tap Sound mode.
    4. Tap Vibrate then tap the left Arrow icon < (upper-left) to return to the previous screen. Selected when a blue dot is present.
    5. Tap Vibration intensity.
    6. Adjust intensity for any of the following (drag the slider left or right to adjust the level): Incoming callNotifications, Vibration feedback and Hard press vibration feedback.

Turn off GPS when not in use

The Global Positioning System (GPS) is used by all apps that provide location services such as Google maps and other apps that give you direction and those that measure your speed or how far you’ve gone. Bluetooth, WiFi and mobile data also use GPS from time to time to give you accuration location. That is the reason why you should turn this feature off when you’re saving battery because it uses battery more than you think.

  1. From a Home screen, swipe up or down from the center of the display to access the apps screen.
  2. Navigate: Settings > Connections > Location.
  3. Tap the Location switch (upper-right) to turn off the service.

Run your Galaxy S9 in Safe Mode

Somebody must have told you that another way to conserve battery in your phone is to disable or uninstall some apps. But which app?

Let’s say you know exactly the apps you want to disable or uninstall but don’t you think it’s too much of a hassle to disable and uninstall them one by one? And after you’ve charged your phone, you will have to do the same thing in reverse to enable them back, right?

Disabling apps is actually one of the best ways to save battery but you don’t have to go through all that to this one simple procedure. There’s a better way to disable them all at one and that’s to run your phone in Safe Mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen appearing on the screen.
  3. When SAMSUNG appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.
  7. While in Safe mode, you can now uninstall apps that are causing a problem.

Again, you don’t have to do all of the procedures here to save battery but that depends on your situation. If you simply want to extend your Samsung Galaxy S9 battery until you have access to an AC outlet, then booting in Safe Mode and turning on Power Saving Mode can actually help you save juice. However, if you simply want to save battery and can afford to miss a message or two, then you can power your phone off for that matter. It depends on you.

I hope this simple article can help you one way or another.
