2. Force Restart Apple Watch & iPhone

How To Force Reset Apple Watch

To force restart your Apple Watch, press and hold both the side button and the Digital Crown for at least 10 seconds, then release both buttons when you see the Apple logo.

How To Force Reset iPhone

  3. To turn your device back on, press and hold the side button (on the right-hand side of your iPhone) until you see the Apple logo

Your Apple Watch and iPhone and interconnected, if your iPhone is having issues this can affect your Apple Watch, which is why resetting both is an excellent way to fix your battery issues, resetting just your Watch won’t do anything if your iPhone is the issue.

3. Adjust Apple Watch Notifications

  1. Go to ‘watch’ on iPhone
  2. Click on notifications
  3. Turn off notifications you don’t want

By default all applications that are cross-platform with iPhone and the Apple Watch will be downloaded to your Watch, making your watch more cluttered with unnecessary notifications and apps, which puts strain on the battery.

Turning off notifications that you don’t want makes your Watch less cluttered, as after all who on Earth wants to play Chess on their Apple Watch?

4. Delete unused Apple Watch apps

  1. Go to ‘watch ‘on iPhone
  2. Click on the app you don’t use
  3. Unselect ‘show app on Apple Watch

The more apps your Apple Watch has, the more RAM your watch will use as apps will constantly refresh in the background putting stress on your watch’s battery.

If you don’t feel a need to have a specific app on your Apple Watch (like Chess!) always remove it, this saves battery and also reduces clutter on your Watches screen so you can find the apps you DO want.

5. Turn Down the Screen Brightness

  1. Go to ‘watch ‘on iPhone
  2. Go to ‘screen & brightness
  3. Select from the 3 available options

The brighter your Apple Watch the more resources it uses from the battery to keep itself bright, setting your default brightness to low will make a huge impact on the battery.

Honestly, there isn’t a huge difference between the brightest level and the lowest, I personally set it to medium, but low is the best option if your suffering from battery issues.

Does your Apple Watch get hot while charging? It’s normal for a battery to get hot charging but not too much, to find out what to do when this happens you can read my helpful guide.

6. Use Workout Power Saving Mode

  1. Go to ‘watch ‘on iPhone
  2. Go to ‘Workout’
  3. Turn power saving mode on

If you use your Apple Watch for running and walking workouts, the display and the watch’s heart rate sensor will be on which drains the battery, turning off these features may reduce the accuracy of estimated calorie burn but your battery will thank you.

7. Turn Off Always On Display

  1. Go to ‘watch ‘on iPhone
  2. Go to ‘Display & Brightness
  3. Go to ‘Always On’ and Switch to off

By default, your Apple Watch is Series 5 or later display is set to always-on, in this mode, the time will always be visible on your watch, and your watch face or most recent app.

Of course, this puts strain on your battery, disabling the feature makes your Apple Watch only turn on when you interact with your Watch.

8. Switch To A Darker Watch Face

  1. Go to ‘watch’ on iPhone
  2. Go to ‘face gallery’
  3. Find a dark watch face and click ‘add’

Your Apple Watch screen is OLED which is why it gets deep blacks and clear colors, but with an OLED screen when the screen is black it’s not displaying black color, rather it’s turning off pixels in that area which uses less energy.

If you use an Apple Watch face that is black this saves you battery as the Watch is using less energy to display the face. The one I recommend if you are having battery issues is the ‘Simple’ face.

Curious if you overcharging your Apple Watch? It’s important to know as you might be damaging the battery, learn the truth in my helpful article.

9. Change How You Use Siri

  1. Go to ‘watch’ on iPhone
  2. Go to ‘Siri’
  3. Turn ‘listen for hey Siri and ‘raise to speak’ off

By default, your Apple Watch is always listening to you, your virtual assistant Siri is always waiting for ‘Hey Siri’ and for you to raise your watch to speak.

Turning both these features off will have a huge impact on battery life, as Siri is always waiting in the background for your commands

10. Adjust Background App Refresh

  1. Go to ‘Watch’ on iPhone
  2. Click ‘background App Refresh’
  3. Select the apps you don’t want to refresh in the background or turn off all of them

Apps that you are not using will automatically check for updates in the background, think apps like Twitter or Facebook, this puts added strain on your Apple Watches RAM which uses the battery.

You can turn off background refresh on an app-to-app basis to switch off background app refresh across your entire Apple Watch to make the biggest impact on your battery life.

With the feature of your only miss out on a couple of seconds saved when the app has to open up and check for new updates, think of Twitter taking a few more seconds to load than usual.

11. Do A Complete Factory Reset

  1. Go to the ’Watch’ app on your iPhone
  2. General > Reset
  3. Erase All Content and settings

Sometimes a factory reset is the only way to get your device working correctly again, you could download a bug or a virus that caused your Apple watch battery to deplete quickly.

It is crucial you do a FACTORY reset not a soft reset, the Watch has to become like it was straight out of the box, if you do a soft reset it will still carry all its files and applications, one of which is likely caused the issue in the first place.

12. Contact Apple Support
