AirPods won’t stay charged/die instantly

I have AirPods A2031, and when I charge them and the case (mainly at night) in the morning after about 1-2 hours of use they die. I have the wireless case to charge them. When I put the AirPods back in the case, after about 5 or so minutes it shows full charge. I take them back out and about 5-10minutes later they die and it just repeats. I have them in the case majority of the day. I have tried resetting them (forgetting the device) and have tried leaving them in the case for 30 minutes to 2 hours (after my phone shows they are at 100%) and it continues to die almost instantly. Any suggestions are appreciated. Thanks in advance
