Apple Watch charging alert
Receive an iPhone notification when the Apple Watch is charging and reaches your selected level from 50 to 100 percent.
Features and setup
One battery view across two devices
Juice Watch shares the battery information that iPhone and Apple Watch make available in the background, then turns it into useful complications and alerts.
Battery status
Check either device from the other
The Apple Watch app receives your paired iPhone battery level. The iPhone app receives your Apple Watch battery level. Juice Watch stores the latest reading so you can see the value and when it arrived.
- iPhone battery level in the Watch app and complications
- Apple Watch battery level in the iPhone app
- Charging state when it is included with an update
- Last-updated context instead of pretending data is live
Learn how to check your Apple Watch battery from your iPhone.

Apple's built-in Battery complication shows the Apple Watch battery. On supported styles, Juice Watch can show iPhone and Apple Watch battery levels together in one complication.
- Choose iPhone or Apple Watch for the number
- Use the gauge for the other device
- Larger styles can show both percentages as numbers
- Quick access to the full Juice Watch app

Update timing
Background updates are periodic
Juice Watch does not continuously poll either battery. iOS and watchOS schedule background work to protect battery life, so updates typically arrive every 5 to 60 minutes. Starting with iOS 17 and watchOS 10, third-party apps receive battery values rounded to the nearest 5 percent.
Recommended setup
Keep updates flowing
A few system settings help iPhone and Apple Watch give Juice Watch regular opportunities to exchange battery information.

Keep the Juice Watch iPhone app and Apple Watch companion app installed.
