So I’ve had every pair of AirPods except for the 3rd generation. I started with AirPods in 2017 then AirPods 2 in 2019, AirPods Pro in 2020 then AirPods Pro 2 in 2022 and now AirPods Pro 2 USB-C in 2024. It seems the lifespan of AirPods for me is every two years the battery life goes downhill and they stop holding a charge. I use them with my iPhone, Apple Fitness+, Apple Watch, Apple TV, and MacBook Pro. This pretty much puts me in the heavy use category. I rotate between two sets of AirPods daily but don’t use optimized battery charging since I need both charged to 100% for usage throughout the day. Initially I tried using optimized battery charging but they wouldn’t be fully charged until later in the day and that didn’t fit my schedule for how I use them. Is the battery lifespan of your AirPods beyond two years? Maybe I need to stop using mine so much because I’m getting tired of having to replace them every two years. Sometimes I miss having wired headphones from back in the day but I love the freedom of AirPods. I guess I should use either use them less or pay for new ones every two years.
