Google’s renewed focus on the Wear OS platform has led to the release of several excellent smartwatches like the Samsung Galaxy Watch 4 and Watch 5, and Google’s Pixel Watch. These wearables represent a significant step up in every department over previous Wear OS watches.
And while they also last longer, their battery life is still only enough for about 24 hours. You can, however, extend the battery life of your Wear OS 3 smartwatch by following the tips below.
1. Disable always-on display
Always On Display is a nice feature to have on your Wear OS smartwatch, but it has a noticeable impact on battery life. Despite all the improvements in OLED display technology over the years, Always On Display can easily consume up to 10% of your watch’s battery life in a day.
So if you want to extend the runtime of your Wear OS smartwatch, you need to turn off Always On Display for good.
- Open the Settings menu on your Wear OS watch.
- Scroll to Display.
- Disable the Always displayed to toggle.
2. Change Screen Timeout
The best way to increase the battery life of your Wear OS smartwatch is to turn off its screen when it’s not needed. You can achieve this by reducing the screen timeout to 15 seconds. After all, the screen doesn’t need to stay on for more than a few seconds after checking the time or closing an app.
- Open the Settings menu on your Wear OS watch.
- Scroll to Display and select Screen Sleep.
- Set the timeout to 15 seconds.
Now your Wear OS smartwatch display will turn off after 15 seconds of inactivity. This small change probably won’t bother you and will help extend the watch’s battery life.
You should also consider customizing the complications on your Wear OS watch face which do not constantly update in the background.
3. Adjust the strength of the vibration motor
The vibration motor inside your Wear OS smartwatch can help you discreetly draw your attention to important calls, notifications, and alarms. But the motor can also consume a lot of battery power.
You can adjust the intensity of the vibration motor on the Galaxy Watch 4 and Watch 5 series. This way, you can continue to get gentle vibration feedback for incoming calls and alerts while limiting the impact on the battery life.
- Open the Settings menu on your Galaxy Watch 4 or Watch 5.
- Scroll down and select Sounds and vibrations.
- From Vibration sub-menu, select Light in the Vibration Intensity submenu.
You also need to disable System vibration in the Vibrate menu. This will reduce the use of the vibration motor, thereby extending the life of the laptop battery.
4. Use Bedtime Mode
You don’t want your Wear OS smartwatch screen to light up or vibrate when new notifications come in at night. This will not only disturb your sleep, but could also irritate your partner.
On the Pixel Watch and Galaxy Watch 4/5, there’s a Bedtime mode that disables all notifications as well as the wake-up gesture. This will ensure that the screen does not turn on automatically when you sleep. All other health sensors continue to work without interruption as they collect important health data throughout the night.
You can sync Bedtime mode with your phone’s Do Not Disturb or Bedtime mode, so you won’t have to manually turn it on every time before you go to bed.
To do this, go to the Wear OS settings menu and select Advanced Features > Bedtime Mode. From there, enable the Turn on as intended to toggle. The mode will automatically sync with your phone’s bedtime schedule.
If you don’t want it to turn on automatically on a schedule, follow the steps below to manually enable Bedtime mode.
- Swipe down from your Wear OS smartwatch face to reveal the Quick Settings panel.
- Press the bedtime mode tile, whose icon has a half moon, to activate the function.
You can turn off the mode by tapping the Quick Settings tile again.
5. Disable “Hey Google” Keyword Detection
You can trigger Google Assistant on your Wear OS smartwatch by customizing the action of one of the physical buttons. Another more convenient way is to say “Ok Google”. If keyword detection is enabled on your Wear OS smartwatch, the assistant will recognize your voice and should be ready to accept your commands.
The problem is that this feature keeps your smartwatch’s microphone on. This hurts battery life and drains a lot of juice.
So, if you want to extend the runtime of your Wear OS smartwatch, you should turn off the always-on “Hey Google” keyword detection. Instead, it makes more sense to map Assistant to one of the watch buttons.
Follow the steps below to turn off the “Hey Google” wake word on your Wear OS smartwatch.
- Open the Settings menu, scroll down and select Google.
- Press on Assistant and turn it off Hey Google to toggle.
6. Use power saving mode
Do you want to extend the battery life of your Wear OS connected watch as much as possible? Use the built-in power saving mode. It will disable all features of your wearable device, including various health tracking sensors and always-on display, decrease screen brightness, and disable various gestures.
On the plus side, it will help extend the battery life of your Wear OS smartwatch by a few hours.
Use the Power saving tile in the Quick Settings panel of your Wear OS smartwatch to quickly activate the mode. Otherwise, jump into Settings > Battery and activate the Energy saver switch from there.
You should also learn how to manage notifications on your Wear OS smartwatch better. Fewer notifications will help extend the battery life of the laptop.
Make your Wear OS smartwatch last longer with these tips
Like your Android smartphone, you need to charge your Wear OS smartwatch daily. Some models, like the Galaxy Watch 5 Pro, offer multi-day battery life, but most models will only last around 18-24 hours on a single charge.
If you’re going to be on the go for a day or two and you know it won’t be possible to charge your wearable device, follow the tips above to extend the battery life of your Wear OS smartwatch.
