Check Battery Life on Your Phone or Apple Watch
You can quickly check your AirPods battery life on your iPhone or Apple Watch.
To check on your iPhone, unlock your iPhone and then open the AirPods next to your iPhone and it will show the battery life of the case and the AirPods.
On your Apple Watch, you can also see your AirPods battery life easily. With the AirPods connected to your Apple Watch via AirPlay, you can open Control Center and tap on the battery percentage.
This opens a second screen that shows your AirPods battery life right on the Apple Watch.
