Delete Unused Apps

Samsung has packed its Galaxy S9 and S9 Plus with many stock apps, but you cannot get the best of Samsung without installing some third-party apps.

Turn Off GPS

GPS is one of the biggest battery killers on your Galaxy S9 devices. While driving through unknown terrains, you may need to keep it turned off to navigate the route, in normal circumstances you should turn off this feature. In case you have to keep it on for a long time, I recommend you to use battery cases or USB C power banks for your smartphone. Along with GPS, you can also turn off other battery killer features like Wi-fi, Bluetooth, and 4G LTE. You don’t use these features when you succumb to a deep slumber, do you?

Use Night Mode

A blue light filter can reduce the battery usage on your Galaxy S9. If you are a pro-user, you can turn on Night Mode filter on your Samsung Galaxy S9/S9 Plus.

Keep “Apps are using battery” Notification ON

‘Apps are using battery’ is a helpful notification your Galaxy S9 sends to make you aware of the battery consumption by certain apps. However, many users find it irritating, and they prefer to turn off “Apps are using battery” notification. Well, you should not do this mistake; keep this notification ON.

Disable Vibrate Mode

It is a good habit to keep your Galaxy S9 on vibrate mode when you are in the office or In the conference. But if you forget to disable this mode, it will surely drain the battery of your phone. Better disable this vibrate mode.

Open Settings → Sound mode and then tap on radio button given before Sound or Mute.

Alternatively, you can customize the intensity of vibration and tactile alerts of notifications.

For this purpose, launch Settings → Sound mode → Vibrate. Now tap on the back arrow on the top left side of your device; here you need to tap on Vibration intensity and adjust each slide bar.

Change Screen Resolution

High screen resolution is another factor that can decrease your phone’s battery life.

Go to Settings → Display → Screen resolution. Here, you can adjust the resolution by sliding the ball to FHD+ or HD+.

Use Save Power Button

You cannot live without social media apps; we all have to agree upon this fact. But then we should also bear in mind that these apps consume a lot of phone battery. No matter how premium your phone is, it is going to face battery issues sooner or later. S9 and S9 Plus allow you to isolate apps that drain the battery of the device.

Launch System → Device maintenance → Battery.

On this screen, you will get to know which app is using how much battery per hour. Here, tap on Save Power button to clear all apps running in the background.

Choose the right Performance Mode

You use your phone for various different purposes; you want to use it as a phone, you may wish to watch movies, listen to music, browse photos, or want to play a game. Galaxy S9 and S9 Plus are equipped with different performance modes. There are four modes. Optimized, Game, Entertainment, and High performance. By default, the device comes with an Optimized mode. For your regular usage, you can keep Optimized mode and adjust the screen resolution to FHD+ (2220 x 1080). When you want more energy, you can change modes that deliver more performance.

Optimization – Clean Up Unnecessary Files/Background apps, and Free Up Memory

OPTIMIZE NOW is a wonder button available in Galaxy S9 and S9 Plus; when you hit this button, it will clean up unnecessary files, apps running in the background and free up some memory.

You can check the score from Settings → Device maintenance; you will also get recommendations on areas to optimize.

Adjust Screen Brightness and Sleep time

Screen brightness, if not adjusted properly, not only drains your phone battery but also causes damage to your eyes. Moreover, your phone’s screen is one of the biggest battery killers; this is why we suggest users disable Always-On Display on Galaxy S9/S9 Plus. In a day, an average user checks his/her phone for more than 140 times. This apparently invokes the brightness of the phone, which consumes battery. It is advisable to keep the screen brightness to less than 50% on your device.

Go to Settings → Display → Brightness; Now you can lower the brightness.

While you are on the screen brightness, you should also check ‘screen timeout’ option on your phone. Screen timeout decides how long your phone’s screen emits light before it turns off or dims down. By default, Samsung keeps it for one minute. This means, when you use and put your phone aside, the screen will dim down after one minute, and for one minute, it will consume battery. You should keep this screen timeout at 30 seconds.

Reboot your device

The last but not the least is to reboot your device. Restarting device has long been used to fix multiple issues. It may sound a meaningless workaround for many; it can solve many problems on your Galaxy S9 or S9 Plus.

To reboot your Samsung Galaxy S9/S9 Plus, just press and hold the power button on the right side of your phone and then select Restart.

That’s all friends!
