The battery life of the Apple Airpods and the AirPods Pro have no significant differences, with the latter having 4.5 hours and the former offering 5 hours. With its charging case, the Apple AirPods can go for at least 24 hours.
The battery life of the Apple AirPods is quite poor compared to regular Bluetooth earbuds in the market or those Bluetooth over-ear headphones. This is even with the premise that you are using an iOS or Mac device that has been optimized to function with the new H1 chip setting.
You can also use the Apple AirPods with an Android phone or device and the lifespan of the battery is still the same. If anything, the H1 chip gives users a stronger connection during a voice call, lessening chances of sounding like you are stuck in a noisy, muddled audio environment. Of course, the quality of the call will also depend on other factors like service coverage, microphone and live volume but overall, the Apple AirPods can get the job done.
