Try these troubleshooting tips if your iPhone does not display a battery notification when your Apple Watch is fully charged.
The Apple Watch charge notification may not show up on your iPhone because the feature could be turned off, or due to system glitches and software bugs. Also, the notification is unavailable on very old Apple Watch models incompatible with watchOS 7 (released almost five years ago) or later. Follow these tips to troubleshoot and fix the Apple Watch charge notification not showing up.
Turn on Charging Reminders
An Apple Watch set up for sleep tracking will remind you to charge it before nap time (if the battery is below 30 percent) and inform you when it’s fully charged, so you can wear it to bed. Open the companion Watch app on your paired iPhone, select the My Watch tab, tap Sleep, and make sure Charging Reminders is turned on.
Use Apple Watch for sleep tracking
If you don’t see the “Charging Reminders” option, make sure you’ve set up your sleep schedule in the built-in Health app on your iPhone (Health > Browse > Sleep > Sleep Schedule).
Return to the Sleep section in the Watch app and tap “Use This Watch for Sleep.” Next, ensure “Track Sleep with Apple Watch” and “Charging Reminders” are enabled. In case these options were already on, tap Don’t Use This Watch for Sleep, restart both devices, and re-enable both options.
Allow notifications for the Watch app
If your iPhone isn’t receiving “fully charged” alerts, go to Settings > Notifications > Watch and make sure Allow Notifications is turned on, then adjust other options like Lock Screen, Notification Center, and Banners.
Restart your iPhone and your watch
Temporary glitches in either your iPhone or your Apple Watch may prevent the battery notification from showing up. If the “Charging Reminders” switch is on but you’re still not receiving them, turn off both the phone and the watch, wait thirty seconds, and turn them back on.
Update all devices
Threads on Apple Communities and Reddit suggest a lot of people had this issue in the initial builds of watchOS 11 and iOS 18. Be sure to update both devices and see if that fixes the problem.
Turn sleep tracking off and back on
Refreshing your sleep schedule in the Health app may cause the battery full notification to reappear on your iPhone. Open the Health app, select the Browse tab, and choose Sleep, then tap Full Schedule & Options and turn off the Sleep Schedule switch. Restart both devices. Finally, go back to the Sleep section in the Health app, turn on Sleep Schedule, and finish setting up your sleep schedule. This should fix the issue; you should receive a silent alert on your iPhone when the Apple Watch battery hits 100% charge.
Erase and restore your Apple Watch from a backup
A user on the Apple Communities forums was able to fix the problem by unpairing the watch, which creates a backup before erasing all settings and data, and restoring it from a backup. This should work even if you set up the device as new (without restoring from a backup).
Reset iPhone settings to the default
Resetting all iPhone settings may fix the disappearing Apple Watch charge notification. If nothing helps, you’ll need to wait until a future software update fixes the issue. Or, preferably, take both devices to your local Apple store for expert assistance.
FAQs
Is there a way to get a sound alert when the watch is fully charged? The Apple Watch charge notification is delivered quietly, and cannot be customized to use sound or vibration.
How to change the notification’s battery level percentage threshold? You cannot change the threshold for this notification so you’ll only be alerted when the Apple Watch batter is fully charged to 100 percent. What you can do instead is configure your iPhone to receive a notification when its battery hits a specific charge like 50%, 80%, or 100%.
