Does an Apple Watch Charge When It’s Off?

Apple Watch is an accountable fitness partner, and one of its perks is that it can go hours before notifying you to charge it. Still, if you’re using your watch all day long, the battery may drain quickly.

You may have tried to turn the watch off to charge it faster, only to find it turned back on once you plug it into the charger. This situation brings us to the question: does an Apple Watch charge when it’s off?

No, it’s not possible to charge the Apple Watch when it’s off. You also can’t use the power-off option once you connect your watch to the charger. 

Continue reading the article to find out how to make your Apple Watch charge faster and maximize its battery performance.

Does an Apple Watch Charge When It’s Off?

Typically, turning off devices may help to charge them faster since less power is consumed. In addition, powered-off devices produce less heat, so your adapter won’t slow down the charging speed to keep the device’s temperature in check. 

If you want to conserve battery or shorten the charging time a bit, you can put your i-watch on airplane mode and turn off Bluetooth

While that won’t make your watch charge at lightning speed, airplane mode might charge the device faster by turning off WiFi, Cellular, and other battery-draining features.

How Long Does It Take an Apple Watch to Charge Completely? 

Depending on the model, the Apple Watch can take between 1.15 to 2.5 hours to fully charge the battery from 0%.

That said, you shouldn’t wait until the battery is dead to connect it to the charger. In fact, letting your electronic devices go below 20% or charge to 100% might affect the battery’s lifespan in the long run. 

You see, each battery has a certain number of charge cycles. A battery charge cycle is when the battery completely recharges from 0%.

Most electronic devices have lithium-ion batteries. This battery type operates through the movement of ions that carry positive and negative charges. These ions come from two metal rods—known as electrodes.

Once you plug the battery into a charger, the ions move from the similarly charged electrode to the oppositely charged electrode, powering the battery. 

When the battery completes a charging cycle, most of the mobile ions are crammed on the electrodes, which strains them, eventually degrading the battery.

For battery life optimization, charge your watch when the battery reaches 20% and unplug the adaptor once the battery is 80%. That’s the sweet spot where there are still free mobile ions, and they’re not spending much time on either electrode.

How to Maximize Apple Watch Battery Performance?

Even when you’re not using your i-watch, the battery may drain faster than expected.

Below are a few tips to help maximize the battery’s performance:

  1. Stop Apps From Refreshing in the Background

When switching between apps, the Apple Watch automatically closes them so the background apps don’t take up battery resources.

However, the refreshing feature allows the apps to check for updates in the background when closed, draining the battery faster. 

Here’s how to turn off the “refreshing” feature to save power:

  1. On your Apple Watch, press the round button to open the home screen.
  2. Tap on the gear icon to open Settings.
  3. Tap on General.
  4. Scroll down and tap on Background App Refresh.
  5. Turn off the Background App Refresh by toggling the green button.
  6. Trim Down the Reminders

While all health apps are helpful to constantly remind you to walk and set newer fitness goals, the notifications can exhaust your battery.

So, even if you don’t use the apps frequently, it’s better to just turn them off altogether.

Here’s how to turn off app notifications:

  1. On your iPhone, open the Apple Watch app.
  2. Tap on My Watch.
  3. Select Notifications.
  4. Tap on the app you want to stop receiving notifications from.
  5. Tap on Custom.
  6. Choose Notification Off.
  7. Switch to Grayscale Mode

While the vibrant colors in the Apple Watch are pleasant, they might shorten the battery’s life. Switching to Grayscale mode when you’re not using the watch can help extend the battery’s run time. 

Here’s how to enable Grayscale mode:

  1. Press the crown button to open the home screen.
  2. Tap on Settings.
  3. Scroll down and tap on Accessibility.
  4. Scroll down and tap on the Greyscale button to turn it on.

It’s not possible to charge your Apple Watch when it’s off. Even when the battery is dead, once you connect it to the charger, the watch will turn back on. However, you can speed up the charging process by turning on airplane mode.

You can also save up the charge by opting for grayscale, reducing reminders, and closing the apps running in the background.

That said, it’s important not to let your watch fully drain or charge it completely, as that may reduce the battery’s lifespan.
