One of the best things about premium smartwatches is that they come fully loaded with useful hardware and software.

The only downside to having powerful hardware with numerous, though, is that it also needs significantly more power than an affordable fitness band.

Here are 5 major tips that you can use to increase battery life on your Samsung Galaxy Watch 3.

These are simple things that your everyday user can do. So, without any further ado, let us get right into it!

1: Disable AOD (Always On Display)

The Galaxy Watch 3 comes equipped with a Super AMOLED display – and that’s primarily why you can use AOD (Always on Display) without killing the battery in a day.

However, that’s not to say that AOD is not consuming any battery life at all. In fact, disabling it is one of the most useful ways to increase battery life on Galaxy Watch 3 devices!

To disable AOD, otherwise also known as Always On Watch face, go to:

  1. Settings.
  2. Watch faces.
  3. Watch always on.
  4. And toggle to “Off.”

This alone is enough to make quite a bit of a difference in battery life.

And if you absolutely must have it enabled, then we’d recommend at least use a dark Watch Face. More about that down below!

2: Use a Dark Watch Face

As we mentioned above, the Galaxy Watch 3 uses an AMOLED display. AMOLED displays can individually adjust each pixel’s power and color.

And whenever there is a black background, the pixels turn off completely.

This means that whenever your watch displays something black, it actually doesn’t display anything at all.

That part of the screen is completely powered off. And that’s why using a dark Watch Face is one of the best ways to increase battery life on Galaxy Watch 3 devices.

In fact, that’s also one of the main reasons why most of the Watch’s UI is dark.

To change your Watch Face:

  1. Touch and hold the watch face’s home screen to enter edit mode.
  2. Swipe until you find a dark Watch Face that you like.
  3. Tap on your desired Watch Face.
  4. And that’s all there is to it.

You can also add more Watch Faces or customize the ones that are to your liking.

3: Lower the Screen Brightness

Even if you are using a dark background, the watch still needs to draw the numbers, date, notifications, and anything else you may have on the home screen.

And the higher that the brightness is for them, the more battery that you end up consuming.

So, to lower the screen brightness on your Galaxy Watch 3:

  1. Bring down the quick panel by swiping down while on the home screen.
  2. Turn it down as low as you can while still being able to see clearly.

This is basically one of the easiest ways to increase your battery life – almost without sacrificing anything at all.

4: Enable “Power Saving Mode.”

As we mentioned above, one of the main reasons that premium smartwatches don’t last as long as much cheaper fitness bands is because they offer a lot more hardware and software.

Disabling some of that functionality, or, in some cases, almost all of it, is one of the most effective ways of increasing your Galaxy Watch 3 battery life.

And the easiest way to do that is by enabling the built-in battery saver. To do that:

  1. Go to settings.
  2. Battery.
  3. Power saving.
  4. And press the tick button at the right part of the screen.

Alternatively, you can also use the battery icon through the quick panel.

This disables wireless connectivity along with pretty much everything else that makes a smartwatch smart.

So, while it’s a very effective way of improving battery life, you should probably only use it when you absolutely need that extra bit of juice.

Or also when the presence of a smartwatch isn’t essential – such as on vacation.

5: Disables Bixby’s “Voice Wake Up” Function

Bixby has a feature that allows you to bring her up with nothing but your voice.

If that’s unnecessary for you, we’d recommend disabling it as it always uses the microphone – which is a tiny bit inconvenient for the battery.

So, to disable Bixby’s “Voice Wake Up”:

  1. Bixby Home.
  2. Options (Three dots at the upper right part of the screen.)
  3. Settings.
  4. Voice wake-up.
  5. Toggle it to “Off.”

It shouldn’t make a huge difference. But every little bit counts.

6: Install the Latest Updates

This doesn’t sound like a big deal. But there are times when Samsung and other manufacturers, too, make huge improvements with nothing but one small update at a time.

So, when you get an update, we’d recommend installing it as soon as you can. Especially the ones that are specifically focused on improving battery life.

To check for updates, you need to:

  1. Open the wearable app.
  2. Head to the bottom.
  3. About watch.
  4. Update watch software.
  5. Update now.

And if there’s an available update, that should install it on the spot.

7: Disable Continuous Heart Rate Monitoring

Heart rate monitoring is one of the most power-intensive features. Disabling it is a good way to improve your Galaxy Watch 3 battery life. Here’s how:

  1. Scroll to your fitness stats.
  2. Click on the heart rate icon.
  3. Scroll down to “HR and stress management.”
  4. And select “Manual measurement only.”

Alternatively, you can also do it through the wearable app’s auto heart rate settings.

After that’s done, you’ll only be able to monitor your heart rate manually by going to Samsung Health.

8: Close Background Apps

It goes without saying that using apps is one of the fastest ways to drain your battery.

But did you know that even if you don’t, apps are running in the background and still draining a bit of battery without you doing anything?

Thankfully, you can close them by doing this:

  1. While on the apps screen, select “recent apps.”
  2. And tap “Close all.”

9: Turn off Wireless Connectivity

When not in use, you should also consider disabling things such as Bluetooth, WiFi, LTE, and maybe NFC too. You can find that option in:

  1. Settings.
  2. Connections.

Mind you, LTE is by far the most power-hungry wireless option.
