But what could possibly be the cause of this issue on your watch?

For starters, updates change your device’s system can cause issues. you must consider a number of factors first before blaming it on the software updates. This can include application usage, background processes, and settings, which are some of the more common factors that cause battery drainage issues.

Now before you go ahead and try to replace your Apple Watch’s battery, try out the below solutions to see if they’re able to fix your Apple Watch.

Without further ado, let’s jump right in.


1. Keep Charging the Watch and Turn It Off.

It is possible that your watch is not giving your battery charge status accurately.

With this, you can always restart your watch if it is not working correctly. But what if the issue is caused by a glitch within the watchOS itself?

In which case, there is a workaround you can do in the meantime that works for some users if a fix is still unavailable. You might want to do this during night time.

Here’s how to effectively charge your watch:

  1. Go ahead and take off your Apple Watch before charging it. Remember to handle your watch and it’s accessories safely.
  2. Then, connect the USB power adapter to the Apple Magnetic Charging Cable or Dock.
  3. Next, plug the power adapter to a stable power source or outlet.
  4. Now, place the charger’s magnet to the back of your watch, and you will see a green lightning icon on the watch screen.
  5. Continue the charging for 4 to 6 hours even though you see the battery charge indicator is 100%.

  1. Finally, leave it off for about 15 to 20 minutes and turn it back on by pressing the Side button again until you see the Apple logo.



2. Check for Unused Connections.

Wi-Fi and Bluetooth connections are common sources where the battery drainage can occur, especially on smaller devices such as your Apple Watch.

Here’s a thumb-rule: the more you use your device connected to the cellular data, Bluetooth, or VPN, the quicker battery is used up.

That is why you only need to use it if you really need it. We recommend that you turn off any such services if you are not using it.


Airplane Mode on Apple Watch


To do that, simply tap the Cellular Data or Bluetooth icon in the Control Center of your watch. If you want to go offline, you can also tap the Airplane icon to enable Airplane mode which is helpful when you want to squeeze out a little more battery life for your device.



3. Mind Your Usage.

Having multiple apps running in the background can eat up a lot of battery resources. You need to be mindful of how you use your applications on your watch. Applications that use high contrast text and graphics can drain your battery faster.

Another feature that might be running on the background is your watchOS updates. If the update is running while you are using your watch, the battery will drain much faster. So it’s expected that you may experience faster battery drainage as the device downloads the latest watchOS updates in the background.

A handy tip would be to schedule the watchOS updates during times when you don’t use your watch, such as night time.

4. Adjust the Settings.

There are a couple of features on your watch that can effectively preserve your battery life.

For instance, the animations from certain graphic intensive apps on your watch can eat up a significant percentage of your battery. Also, the more your watch is active, the more it will consume the battery.

Minimizing the usage of these features and only using them when they are intended will help preserve the battery life.

Here’s how to disable these battery consumers in your settings:

  1. Go ahead and open the Watch app on your iPhone that is paired with your Apple Watch.
  2. Then, tap on the My Watch tab at the bottom of the screen and tap on General options.
  3. Now, tap on Accessibility and enable the Reduce Motion option and disable the Reduce Transparency option.
  4. After that, go back to your Apple Watch screen and open the Control Center.

But if you are in a tight spot and need to preserve your remaining battery until you get home to charge, you can always enable the Power Reserved mode. This will, of course, limit the usability of your watch to conserve battery.



5. Limit your Notifications.

It is not necessary to push all of your notifications to your watch when instead, it can be checked on your iPhone.

Unlike your Apple Watch, your iPhone has more than enough battery capacity to handle these tasks.

Here’s how you can disable notifications on your Apple Watch:

  2. Then, tap the My Watch tab, and then tap on the Notifications option.
  3. Now, tap the name of the app that you want to disable the notification push to your Apple Watch.
  4. Tap on the Notifications Off option so the app will not send notifications to your Apple Watch.

If you want to temporarily disable all notifications, you can also enable the Do Not Disturb feature by tapping on the half-moon icon from the Control Center.



6. Remove Unused Apps.

Having unused apps installed can also be a source of excessive battery drainage on your Apple Watch.

In which case, you can either choose to update these apps or remove them entirely. We recommend the latter where if you’ve to find yourself not having used the app in the past few weeks, months then you might as well remove it from causing any problems.

Doing this can also free up some of your storage on your Apple Watch and will overall help improve with the responsiveness.
