AirPods teardown reveals tightly-packed circuitry and so much glue

As has become traditional with each new Apple product, iFixit has performed a teardown of the AirPods wireless earphones. The teardown gives a look at the AirPods' W1 wireless chip, tiny internal circuitry, and glue.

As part of the teardown, iFixit offers a look at the battery found in one of the AirPods, which is set to last around five hours per charge:

Digging deeper under more glued-on cables and tape, we find some markings etched into the battery. Looks like this is a 93 milliwatt hour battery—equivalent to a little over 1% of the charge capacity in an iPhone 7.

As befits the small frame of the AirPods, Apple has packed in a lot of electronics into a tiny space. This includes the W1 chip, which facilitates the AirPods' simple setup, connection, and switching between Apple devices.

The teardown also opens up the AirPod charging case, giving us a look at its chips and battery, which Apple says should provide an additional 24 hours of life to the AirPods when fully charged.
