Lock Screen widgets
Choose the batteries in your widget
Lock Screen widgets require iOS 16 or later on iPhone, or iPadOS 17 or later on iPad.
Add the widget
- Touch and hold your Lock Screen, then tap Customize. Choose Lock Screen if asked.
- Tap the widget area or Add Widgets, then choose Juice Watch.
- Add the rectangular Battery Levels widget. Remove another widget if you need more space.
- Tap Battery Levels while you are still editing the Lock Screen to choose its batteries.
- Close the widget editor, then tap Done to save your Lock Screen.
Choose your batteries
Top Battery, Middle Battery and Bottom Battery set the order. To move a battery, select it in a different position.
Bottom Battery is optional. Choose No third battery to leave it empty. The default choices are iPhone, Apple Watch and no third battery.
Selecting the same battery more than once shows it only once. Each widget copy can have different choices.
Available devices
On iPhone, you can select this iPhone, Apple Watch and shared iPads shown in Juice Watch. Apple Watch readings require a paired Apple Watch.
On iPad, choose this iPad by its device name to show its battery. iPhone and Apple Watch are selected by default; connect your iPhone in Juice Watch to show their readings. Other iPads are not available in this iPad’s widget.
Custom device names appear in the editor. If you have not set a name, Juice Watch uses a short device name. Renaming a device keeps your selection.
Reading the widget
With one or two batteries, the time label shows the age of the oldest displayed reading, or says No reading available. With three different batteries, the third battery takes the place of the time label.
Readings can be delayed when devices are offline or apps are in the background. The time label is not a countdown to the next update.
If a battery is missing
If a battery is unavailable, open Juice Watch and check that the device appears there. On iPad, check the iPhone connection if its readings are missing. A missing device is not replaced with another device.
If the widget asks you to open Juice Watch, follow that instruction to check access, load readings or reconnect your iPhone. Open app to unlock refers to Juice Watch access; you can restore an existing purchase in the app.
FAQ
Battery updates and notifications
How often does Juice Watch update battery levels?
Battery readings are periodic, not real-time. iOS and watchOS decide when background work runs, so Juice Watch typically receives updates every 5 to 60 minutes. Opening the apps can create another opportunity to exchange the latest available information.
Why are battery levels shown in 5 percent increments?
Starting with iOS 17 and watchOS 10, Apple makes battery information available to third-party apps in values rounded to the nearest 5 percent. Juice Watch displays the value provided by the system.
Does Juice Watch need an Apple Watch complication?
For expected background updates, keep the Juice Watch companion app installed and add a Juice Watch complication to your active watch face. The complication also keeps the latest iPhone battery level visible at a glance.
Can one complication show both iPhone and Apple Watch battery levels?
Yes. On supported styles, Juice Watch can show iPhone and Apple Watch battery levels together in one complication. One device can appear as the number and the other as the gauge, while larger styles can show both percentages as numbers. Apple's built-in Battery complication shows the Apple Watch battery only.
What should I check if a battery level is not updating?
Confirm that both Juice Watch apps are installed, a Juice Watch complication is on the active watch face, Background App Refresh is enabled, and Low Power Mode is off. Then open Juice Watch on both devices and allow time for the next system-scheduled update.
Can I choose when charging notifications arrive?
Yes. You can choose a charging threshold from 50 to 100 percent for each supported device. Juice Watch evaluates available battery updates and sends a notification after the reading crosses your selected level while charging.
Can I check Apple Watch battery on iPhone?
Yes. Open Juice Watch on iPhone to see the last Apple Watch battery level received from the companion app and the time it was received. The value is periodic rather than real-time.
Why did a notification arrive later than the exact threshold?
Juice Watch checks the readings that iOS and watchOS make available in the background. If the system delivers the next update after the battery has moved beyond your selected threshold, the notification reflects that later reading.
How do I restore a purchase?
Open Juice Watch on iPhone, open the purchase screen, and choose Restore Purchases. Make sure the device is signed in to the same Apple Account used for the original purchase.
