How To Check Apple Watch Battery Level

Knowing how to check Apple Watch battery level is a fundamental skill for any owner. Monitoring your Apple Watch’s remaining power is as simple as adding a battery complication to your watch face. This guide covers every method, from a quick glance to detailed iPhone widgets, ensuring you’re never caught off guard by a low battery.

The most immediate way to see your battery is right on your wrist. Your Apple Watch provides several built-in options that take just a second.

Using A Watch Face Complication

This is the fastest method. A complication is a small widget you can add to most watch faces.

Firmly press on your current watch face to enter the customization screen.
Tap ‘Edit’.
Swipe left all the way to the complications screen (you’ll see small highlighted areas).
Tap on a complication slot you want to use, like the corner or a section beside the time.
Turn the Digital Crown to scroll and select the ‘Battery’ complication.
Press the Digital Crown to save, then tap the face to set it.

You will now see a persistent battery percentage or icon on your watch face. Some faces even offer a circular battery gauge complication.

Accessing Control Center On Your Watch

If you don’t have a complication set, the Control Center is your next best option.

From any screen on your Apple Watch, press the side button (the one below the Digital Crown).
The Control Center will appear, showing icons for connectivity, audio, and more.
Look for the battery percentage icon. It’s usually in the top section.
Tap the battery icon once to see if Power Reserve mode is available, but just viewing it shows your current charge.

This method works regardless of which watch face or app you are currently using, making it incredibly reliable.

Checking From The Watch Face Directly

Some watch faces, like Modular, Modular Compact, or Utility, have a dedicated large-area complication that can show detailed battery info. When you add the Battery complication to these large slots, it often displays the percentage number clearly without needing to tap. This is the most at-a-glance method available.

Understanding The Battery Icon Colors

When you check, note the color of the battery icon:

Green: Battery is in a normal charging state or is above 20%.
Red: Battery is critically low (below 20%). You should charge soon.
Yellow: Battery is in Low Power Mode (a feature introduced in watchOS 9).
Lightning Bolt (inside icon): The watch is currently charging.

Using Siri For A Hands-Free Check

If your hands are full, you can simply ask. Raise your wrist and say, “Hey Siri, what’s my battery level?” or “Hey Siri, how much battery is left?” Siri will respond verbally and display the percentage on screen. This requires your watch to be connected to power or your iPhone, but it’s a great accessibility feature.

How To Check Apple Watch Battery From Your IPhone

You don’t always need to look at your watch. Your iPhone is a powerful hub for managing your Apple Watch, including monitoring its power.

Using The Apple Watch App

The dedicated Apple Watch app on your iPhone has a battery section.

Open the Apple Watch app on your iPhone.
Tap the ‘My Watch’ tab at the bottom left.
Scroll down and select ‘General’.
Tap ‘Usage’. Here, you’ll see your Apple Watch’s current battery percentage.

This screen also shows usage time and standby time since your last full charge, which is helpful for diagnosing battery drain issues.

Adding The Batteries Widget To Your IPhone

This is arguably the most convenient iPhone method. The Batteries widget shows the charge of all your connected Apple devices.

Long-press on an empty area of your iPhone Home Screen or Lock Screen until the apps jiggle.
Tap the ‘+’ button in the top corner to add a widget.
Search for “Batteries” or scroll until you find the Batteries widget.
Select a widget size (the medium or large size shows more devices clearly).
Tap ‘Add Widget’, then place it on your Home Screen.
Tap ‘Done’ in the top right.

The widget will now display your Apple Watch’s battery level alongside your iPhone, AirPods, or other accessories. It updates regularly so you can check with just a glance at your phone.

Viewing Battery Level During Charging

When you place your Apple Watch on its charger, the screen should automatically wake up and show a large green charging icon with the percentage. If it doesn’t, you can tap the screen once to wake it and see the current charge level. This is the best time to check how much it has charged since you put it on the magnet.

Advanced Battery Management And Settings

Beyond just checking the level, you can take control with features designed to extend your daily battery life.

Enabling Low Power Mode

Introduced in watchOS 9, Low Power Mode temporarily reduces background activity to extend battery life when you’re running low.

Open the Control Center on your Apple Watch (press the side button).
Tap the battery percentage button.
Toggle on ‘Low Power Mode’.
Choose to turn it on for 1 day, 2 days, or 3 days.

In this mode, the battery icon turns yellow. Some features like always-on display, background heart rate measurements, and workout reminders are limited. It turns off automatically once you charge your watch past 80%.

Checking Battery Health

Like the iPhone, your Apple Watch has a Battery Health metric. This shows your battery’s maximum capacity relative to when it was new.

On your Apple Watch, open the Settings app.
Scroll down and tap ‘Battery’.
Tap ‘Battery Health’.
Here you’ll see ‘Maximum Capacity’. A percentage of 80% or below indicates a battery that may need servicing.

This information helps you understand if your watch’s reduced runtime is due to settings or an aging battery that’s lost some of its ability to hold a charge.

Setting Up Charge Reminders And Notifications

Your watch can help you build better charging habits. In the Watch app on your iPhone, go to Settings > General > Usage. Here, you can enable ‘Charge Reminders’. Your watch will then suggest a charging time based on your daily routine, aiming to have it fully charged when you typically start your day. Also, you will get a notification on both devices when the battery dips to 10% and again at 5%.

Troubleshooting Common Battery Display Issues

Sometimes, the battery percentage might not appear or seem inaccurate. Here’s how to fix common problems.

Battery Percentage Not Showing

If the number disappears from the complication or Control Center, try these steps:

Restart your Apple Watch. Hold the side button until the power off slider appears, then drag it.
Check for software updates on your iPhone in the Watch app under General > Software Update.
Remove and re-add the Battery complication to your watch face following the steps earlier.
Ensure your watch isn’t in Power Reserve mode, which only shows the time. Exit it by holding the side button until the Apple logo appears.

Battery Draining Too Quickly

If you find yourself checking the battery too often because it falls fast, consider these adjustments:

Reduce screen brightness in Settings > Display & Brightness.
Shorten the wake screen duration in the same settings menu.
Review which apps are using the most power in Settings > Battery on the watch.
Limit always-on display use if you have a Series 5 or later (Settings > Display & Brightness).
Make sure you have a good cellular or Wi-Fi signal, as poor connectivity forces the radio to work harder.

A sudden drop in battery life can sometimes be fixed by simply restarting both your watch and paired iPhone.

Widget Or Complication Not Updating

If the Batteries widget on your iPhone or the complication on your watch seems stuck, force a refresh. For the iPhone widget, try removing it from your Home Screen and adding it back. For the watch complication, try switching to a different watch face and then switching back. This often resets the data connection and updates the displayed information.

Frequently Asked Questions

How Can I See My Apple Watch Battery Percentage All The Time?

To see the percentage constantly, you need to add the Battery complication to a watch face that supports it. Choose a face like Modular or Infograph and place the complication in a prominent slot. The percentage will then be visible whenever you glance at your watch, without any need to swipe or tap.

Why Is My Apple Watch Battery Dying So Fast?

Rapid battery drain can be caused by several factors. Common culprits include a new watchOS update that needs a few days to settle, overuse of power-intensive features like GPS during long workouts, constant use of cellular connectivity without your iPhone nearby, or a background app that’s stuck. Checking the Battery section in the Watch’s Settings app will show you which apps are using the most power recently.

Can I Check My Apple Watch Battery From My Mac?

There is no direct, built-in way to view your Apple Watch battery on a Mac. The most effective method is to use the Batteries widget on your iPhone, which is often nearby. Alternatively, some third-party apps on the Mac App Store can display iOS device batteries if your watch is connected to the same network, but the iPhone methods are more reliable and immediate.

What Does The Red Lightning Bolt Mean On My Apple Watch?

A red lightning bolt symbol on your Apple Watch screen indicates that the battery is extremely low and needs to be charged immediately. It’s different from the green lightning bolt you see during normal charging. When you see the red bolt, you should connect your watch to its charger as soon as possible to avoid it powering off completely.

How Do I Know If My Apple Watch Battery Needs Replacing?

Go to Settings > Battery > Battery Health on your Apple Watch. Look at the ‘Maximum Capacity’ percentage. If it is significantly below 80%, your battery has degraded and holds less charge, which is a sign it may need replacement. Also, if you experience unexpected shutdowns or the watch will only run for a few hours even with minimal use, it’s time to contact Apple Support for a battery service diagnosistic.
