Smartwatches, as well as smartphones, for many people, is a fundamental device and is now fully integrated into the daily routine. Those used to having it on their wrist use it to check notifications, calls, messages, and emails with a single glance, to monitor the quality and quantity of physical activity, sleep, and even heartbeat, consulting it and using it dozens of times a day. . Which means that it is vital to know how to increase the battery life on the smartwatch to prevent it from running out before the end of the day.
As for smartphones, therefore, also for the smartwatches there are a series of measures that allow you to extend the battery life, some very intuitive, others less obvious. Here are a few, depending on whether you use an Apple Watch, a Wear OS device, or a proprietary smartphone.
How to increase the battery of the Apple Watch
Apple claims that the battery life of the Apple Watch is about 18 hours, but calculated on the basis of precise use: 90-time controls, 90 notifications, 45 minutes of app use, and 60 minutes of training with music playback from Apple Watch via Bluetooth.
Battery life actually depends on usage, configuration, cellular network, signal strength, and many other factors (including the use of fast charging ), and actual results may vary.
To increase its duration, a series of measures recommended by Apple itself can therefore be adopted:
- Update the software to the latest version of watchOS to make sure it is at peak efficiency. To see if there are any updates, open the Apple Watch app on your iPhone and tap Apple Watch> General> Software Update. If an update is available, connect the iPhone to a Wi-Fi network, connect the Apple Watch to the charger (make sure it is at least 50% charged) and perform the update wirelessly.
- Activate power saving mode when running or walking to turn off the heart rate monitor. To activate the power saving mode, you need to open the Apple Watch app on the iPhone, tap Apple Watch> Workout and turn on “Energy Saver”. However, when the heart rate monitor is not active, the calculation of calories burned may be less accurate.
- Use a Bluetooth chest strap: For longer workouts, instead of the built-in heart rate monitor, you can use a Bluetooth chest strap to save the battery of the smartwatch. To pair it with the watch, the band must be in Pairing mode, so you need to open Settings on Apple Watch, choose Bluetooth and select it in the “Medical Devices” list.
- Disable automatic screen wake-up: To prevent the watch display from turning on every time you raise your wrist, you can disable this feature. To do this you need to open Settings on your Apple Watch, select General> Activate screen, and disable “Activate the screen when you raise your wrist”. To activate the display, simply touch it or press the Digital Crown.
- Keep Bluetooth On: Contrary to popular belief, Apple Watch’s battery runs out faster if you turn off Bluetooth on your iPhone. To optimize the energy consumption of communications between devices, it is, therefore, better to keep Bluetooth always active.
- Use the Low Power option: Low Power Allows you to view the time on the Apple Watch without reducing battery life. When Apple Watch is in Low Power mode, to see the time you need to press the side button (in short, it is not enough to lift your wrist), it does not communicate with the iPhone and you cannot access the other functions of the watch. To activate Low Power, you need to swipe up on the watch face to open Control Center, tap the battery percentage and drag the Low Power mode slider, then tap OK. When the battery charge drops below 10%, the Apple Watch itself warns and asks if you want to switch to Low Power mode. When the battery is too low, Apple Watch automatically enters Low Power mode and displays next to the time.
How to increase Wear OS battery
For Wear OS smartwatches, Google itself provides a series of tips and tricks to make the battery last longer and optimize its performance.
- Set the screen to turn off automatically: You can set the screen to turn off when you are not using the clock instead of always showing the date and time. To do this you need to swipe down from the top of the screen, tap Display Settings, and then Always On Screen at the bottom of the screen to turn the option on or off.
- Temporarily turn off the screen: this way the watch does not light up and does not show notifications, even when you touch it or move your wrist. To temporarily turn off the screen you need to turn on the clock, swipe down from the top of the screen, and tap Cinema Mode.
- Use another watch face: Some watch faces, especially those with animations and interactive features, consume more battery than others. Choosing a simpler one will save battery.
- Adjust the screen brightness: The higher the brightness of the clock screen, the more battery is consumed. To reduce the brightness you need to activate the smartwatch, swipe down from the top of the screen, tap Settings> Display> Adjust brightness and then choose the degree of brightness of the screen.
- Disable unwanted notifications: To disable unwanted notifications, open the Wear OS app on your phone, scroll down to “Settings” tap Notifications> Block app notifications and then select the app you want to block. To block notifications from another app, tap Add more.
- Uninstall apps: If you have recently installed an app and find that the battery runs out faster than usual, you can try uninstalling the app. To uninstall a watch app you need to: activate the watch, access the app list, press the power key, scroll down and tap Play Store, swipe down from the top of the screen and tap My app, tap the app you want to delete, scroll to the bottom and tap Uninstall.
- Check battery life and usage: with the Wear OS app you can get more detailed information about the battery, such as apps that are draining the watch battery, battery life estimate, battery charging times ( when plugged into a power outlet, and battery life graph. To view battery details via the app, open the Wear OS app, scroll down to “Settings” and tap Advanced settings> Battery clock.
General tips for increasing the battery life of smartwatches
Then there are general tips to make the smartwatch battery last longer regardless of model and operating system.
Here are some of them:
- Update the software to the latest version of the operating system to make sure it is at peak efficiency
- Lower the screen brightness
- Block notifications for apps that cost a lot of energy
- Limit connectivity: WIFI, NFC, and geolocation connections increase battery consumption
- Block gestures via the wrist: most smartwatches have a feature that involves automatically turning on the screen when you move your wrist. Deactivating it can save battery.
