Disable Always-On Display

Always On Display is a fantastic feature that keeps us up to date with Time, Messages, and Notifications, by just raising the wrist, and most importantly, it doesn’t require any human intervention of pressing buttons or anything. At the same time, when you don’t want to see time or notification but have just raised the wrist for another purpose, the Galaxy Watch 4 will light up, leading to a battery drain.

  1. Unlock your Galaxy Watch 4, and open the Settings app.
  2. Locate and tap Display.
  3. Find Watch Always ON and disable it.

Disable Wake-Up On Assistants

Earlier, we would need to press a button to call a Virtual Assistant like Bixby, S Voice; however, that time is long gone, now the watch is gotten even smarter, and these assistants remain active all the time, and upon calling them, the assistant will reply you back. Which obviously consumes more battery.

  1. Open the Bixby or S Voice in your Galaxy Watch.
  2. Tap on three dots for more options.
  3. Disable Voice wake-up.

  2. Find and open Notifications.
  3. Choose the one which you think will consume less battery and could probably improve battery life.

Remove Unnecessary Apps

Like smartphones, with Samsung Galaxy Watch, there are many apps that come pre-installed, and unfortunately, we don’t need them at all. Apart from this, we must download apps we need in our daily routine. Apparently, these apps constantly use the battery to update resources, even when the Watch is in an idle situation. Therefore, uninstall the applications that you don’t need. Touch and hold the app icon and Delete it.

Free Up Storage

  • From the phone, navigate to Galaxy Wearable App.
  • Hit About Gear or About Watch.

  • Deselect the apps you want to keep running in the background, and then hit Clean Now.

Do Not Place The Watch In Heat Exposure

Keeping the Apple Watch in contact with hot or cold temperature can drastically decrease the Watch’s Battery Life and eventually leads to serious damage. Considering this scenario, we always suggest keeping it safe from such an atmosphere. 

Enable Power Saving Mode

When Power Saving Mode is enabled, your watch’s Main Screen will be displayed in Grayscale, and all features will be disabled, except Messages, Calls, Bluetooth, and Notifications that use Wi-Fi. However, the Mobile Data will be disabled, and performance will be restricted. 

  1. Press the Home Button on the Apple Watch. Select Settings from the App Tray. It depends on the Watch; you may need to select Battery or Battery Management. 
  2. Then, select Power Saving > Checkmark to enable Power Saving Mode.
  3. Similarly, disable Power Saving Mode, choose OFF your Watch Main Screen, and then choose Checkmark. 

Now after, enjoy the watch with limited features.

Force Restart
