Why is my Apple Watch battery draining so quickly? How to fix it


On average, the Apple Watch lasts 18 hours after a full charge. But since you will have to use the watch more than 20 hours a day, the battery life is not enough. Due to the short battery life, the Apple Watch also has no sleep tracking features.

So why does this happen and how to improve your Apple Watch battery life? Let’s look at this.

Why does the Apple Watch battery drain so quickly?

It is difficult to pinpoint the exact causes of a rapidly draining battery. But the potential cause may be the iWatch itself as it cannot last long. Moreover, if the screen is turned on quite frequently, this can also be a reason for the short battery life.

Here are some other possible reasons why your Apple Watch battery is draining very quickly:

  • Extended wake-up screen time
  • Background app refresh is enabled.
  • Brightness is too high.
  • Latest iOS Updates

How to Improve Apple Watch Battery Life?

The main reason for short battery life on most devices is the display. The more you turn on the screen of an Apple Watch or an iPhone, the more the battery consumption will increase. So, let’s start with solutions to reduce screen time on your iWatch.

Reduce/disable screen activation time

There are a few settings you can change to reduce screen turn-on time on your Apple Watch. Usually, the iWatch turns on its screen when you raise your wrist or tap the screen. The screen will stay on for a set time based on your settings.

You have two options for your wake-up screen time. You can either select 70 seconds or 15 seconds. We recommend choosing the latter option to reduce battery consumption.

To note: When changing iWatch settings, make sure your watch is close to your iPhone.

  1. Open the Watch app on the iPhone.
  2. Go to the My watch tab and select General.
  3. Press on Wake screen.
  4. Select the Wake up for 15 seconds option.

Additionally, you can also slide the toggle to disable the Screen wake up when raising wrist option. This little trick can help save battery life. You can now only turn on your iWatch by turning on the Digital Crown or tapping the screen.

Reduce brightness

Another way to save battery is to lower the brightness. On your Watch the application, select the application Display and Brightness option. Drag the toggle to decrease the brightness.

  2. Go to Accessibility.
  3. Now you can see the Reduce movement option. Select it and slide the toggle to turn it on.

deactivate the notifications

If you want more ways to reduce your screen time on your iWatch, you can also turn off notifications. In this way, you can directly consult all the notifications when you are free. To disable notifications, please follow these steps:

  1. In your phone’s Watch app, tap Notice.
  2. Then scroll down and turn off any notifications you don’t think are necessary.

Disable Background App Refresh

Background app refresh means that your apps keep updating or running in the background which consumes a lot of battery. So, you can simply disable this option to save battery on your iWatch.

  1. Go back to your Watch the app and go to General.
  2. Scroll down until you reach the option Refresh the app in the background.
  3. Tap it, then slide the toggle to disable the feature.

Please note that you may need to keep Background App Refresh enabled for a few important apps, such as Alarms, iMessage, etc. So, instead of disabling the option, scroll through the apps and disable only certain apps that you don’t want to run in the background.

Manually end training mode

When you use Apple Watch during workouts, it continues to measure your heart rate. This will significantly increase battery consumption. So it’s best to swipe the screen to the right and tap To finish to manually end training mode.workout mode-iwatch

Activate power saving mode

Another easy way to save battery on your Apple Watch is to turn on Power Saving Mode. This will prevent apps from running in the background, turn off the display when not needed, and reduce overall battery consumption.

Turn off Wi-Fi and Bluetooth when not in use

Wi-Fi and Bluetooth constantly refresh your iWatch data, resulting in higher battery consumption. So whenever you’re not working out and need to have Wi-Fi and Bluetooth turned on, we recommend turning them off.

Open your iWatch and open Settings. Go to Wireless and turn it off. Then go to Bluetooth and turn it off as well.

Reset and re-pair Apple Watch

If most of the solutions don’t work, you can reset your Apple Watch and then pair it with your phone again. This can help stop all background processes and save battery.

  2. Press on General.
  3. Scroll down and tap Reset.
  4. Now press Erase Apple Watch content and settings. erase-apple-watch-content

  1. Go to the Watch the app and select the app My watch tab at the top.
  2. Tap the “I” icon on the right side.
  3. Select Unpair apple watch and confirm your action.

Then, to re-pair your iPhone, tap Start pairing on your Watch app then select Set up for myself. Position the camera above your iWatch for successful pairing.

Delete unnecessary apps

One of the final solutions that you can try is to remove unnecessary apps. This will reduce excessive communication between your iWatch and your phone.

Open your Apple watch and browse your apps. Hold down any app you no longer want. Your watch will now ask you to confirm the removal of the app. Press on Delete app.

Update Apple Watch

Finally, you can also try updating your Apple Watch. Indeed, each new iOS update comes with many new optimizations which may also include the battery. To update your iWatch, you can simply use your iPhone and install all available software updates.
