Battery chemistry is a complex matter, and the constant charging and discharging complicate it even further. While Li-ion batteries are rated at a certain nominal capacity, the rate of discharge makes a huge difference in endurance and life span.
The packs inside are both with miniscule capacity, and subjected to abnormal rates of constant charging and discharging, the worst of both worlds for tiny batteries. Some people use only one AirPod at a time, others listen until the battery is completely dead and then recharge fully - the true wireless earbuds' usage is a far cry from a large phone battery that you usually charge in the evening, and that's that.

This is why, in light with the revelation that the new AirPods Pro battery is not really replaceable, we wanted to ask you if you have noticed any significant degradation of your vintage AirPods battery life with time.

Tell us what battery life were you getting in the beginning with your type of usage, and what did it become after two, or maybe even one year of daily wear and tear.
