A:Answer So the blinking white could be that your AirPods aren't actually paired with a device. If they are paired, and it's still blinking, blinking white is more of an indicator of the charge of the case itself. When the case needs to be recharged, it will blink orange.
The best way to tell the charge level of the AirPods themselves is with the software on the device that you connected them to. Any Apple device will automatically show you the status of the care and each bud once you open the case and they are paired with the device. You can also go into the settings and see them there.
Similarly, if you use these for an Android device, newer Android devices will behave similarly, showing you the status once the case is open or you check in the Bluetooth settings.
