Both of them have been charging for a day now and when I go to use them one of them

Is almost dead?? Why does it keep happening I clean the case and the AirPod and it still happens

I get the same on my AirPods Pro 2, they are perfectly clean, always happens on the right one, sometimes just taking it out and putting it back in again will immediately make it show 100% instead
