Apple Watch does not have a built-in Apple complication for showing the paired iPhone’s exact battery percentage. You can add that information with a third-party app such as BatteryPhone, but its reading is periodically refreshed—not guaranteed to be live. For the most current percentage, check the iPhone itself.
Can Apple Watch show the iPhone battery percentage natively?
Not through Apple’s built-in battery controls. Pressing the Apple Watch’s side button opens Control Center, but the percentage shown there is the Watch’s own battery level.
Apple documents the reverse arrangement: the iPhone’s Batteries widget can show the charge level of a connected Apple Watch. Apple does not currently document a native Apple Watch complication that displays the iPhone’s exact percentage. This is a limitation of Apple’s documented features, not a claim that the Watch cannot receive any battery information from the iPhone.

How to show the iPhone battery percentage on Apple Watch
A third-party complication is the practical workaround. BatteryPhone is listed as free in the U.S. App Store when checked and its listing says it supports iOS 26 and watchOS 26.
- On the paired iPhone, open the App Store.
- Search for BatteryPhone by Keietsu Yasuhara, then install it.
- Open BatteryPhone on the iPhone at least once so it can read and communicate the phone’s battery status.
- Open the iPhone’s Watch app. If BatteryPhone’s Watch component was not installed automatically, find it in the available apps section and install or enable it.
- In the Watch app, open the active watch face and tap Edit.
- Choose an available complication position, then select a BatteryPhone complication. Watch faces support different complication families, so the exact position and layout will vary.
- Choose the BatteryPhone layout that shows the iPhone battery. Some layouts can show both iPhone and Apple Watch levels.
- Return to the watch face and allow the complication to populate. If it remains blank or becomes stale, tap it or open BatteryPhone on the Watch to request an update.
The exact installation labels can differ slightly between watchOS versions and depending on whether the Watch app installs automatically. BatteryPhone’s App Store listing confirms complication support, combined device displays, and manual refresh guidance.

Is the BatteryPhone percentage live?
No. BatteryPhone says its complication generally updates approximately every 12 to 60 minutes, depending on iOS and watchOS behavior. The interval is not exact, and automatic updating can stop. Its version history also notes that iOS restrictions can limit immediate updates to 50 times per day in some circumstances.
That means the number on the Watch may be the iPhone’s last reported charge rather than its current percentage. Tapping the complication may restart or trigger an update, but it does not turn the complication into a second-by-second monitor.

Use the complication for convenience and a quick glance. If the exact current percentage matters—especially before leaving home or starting a long trip—check the iPhone directly.
If the iPhone and Apple Watch are disconnected
The workaround depends on communication between the paired devices. If the iPhone is out of communication range, powered off, or otherwise unavailable, BatteryPhone may continue showing the last reported value or fail to update. A number that does not change, or a displayed update time that is old, should be treated as potentially stale.

No app can retrieve a newly reported percentage from an iPhone that cannot communicate its current state. Reconnect the devices and then refresh the complication, or check the iPhone itself.

BatteryPhone troubleshooting
The complication is missing
- Confirm BatteryPhone is installed on the iPhone.
- Open the iPhone’s Watch app and check whether its Watch component is installed.
- Edit the active watch face and select BatteryPhone in a supported complication slot.
- Try another watch face or complication family if the desired layout is unavailable.
The complication shows a dash or no number
- Open BatteryPhone on the iPhone.
- Confirm that the Watch is paired and connected.
- Open BatteryPhone on the Watch.
- Tap the complication.
- Restart both devices if necessary.
- If the issue started after an operating-system update, reinstall the Watch component. BatteryPhone’s listing recommends restarting or uninstalling and reinstalling the Watch app component when complications stop updating.
The number is outdated
- Check the update time if the selected layout displays one.
- Tap the complication to request a refresh.
- Remember that background-refresh rules prevent continuous updating.
- Check the iPhone directly when accuracy is important.

- Control Center: On Face ID iPhones, swipe down from the top-right corner of the screen.
- Status bar: Go to Settings > Battery > Battery Percentage. On Face ID models, the percentage appears inside the battery symbol.
- Batteries widget: Add Apple’s Batteries widget to the iPhone Home Screen or Lock Screen to view the iPhone and connected accessories.
Apple’s current instructions are available in its iPhone User Guide.
How to check the Apple Watch battery itself
- Press the Apple Watch’s side button to open Control Center.
- View the battery percentage shown there.
- Tap the percentage for a larger battery ring and Low Power Mode controls.
You can also add Apple’s own battery complication to a supported watch face. This shows the Watch’s battery—not the paired iPhone’s percentage. Apple explains these controls in its battery support guide.
Which option should you use?
| What you need | Best option | Main trade-off |
|---|---|---|
| A quick glance at the iPhone level from your Watch | BatteryPhone complication | The value may be 12–60 minutes old. |
| The most current exact percentage | iPhone Control Center or status bar | You must use the iPhone. |
| No third-party app | iPhone Batteries widget | It cannot place the iPhone level on the Watch face. |
| Your Watch’s own battery level | Watch Control Center or Apple battery complication | It does not show the iPhone percentage. |
Bottom line
Apple does not currently provide a native way to place the iPhone’s exact battery percentage on an Apple Watch face. BatteryPhone can add an iPhone battery complication, but its value is periodically refreshed and may be stale. Use it for convenience; use the iPhone’s Control Center, battery percentage setting, or Batteries widget when you need the authoritative current reading.
