Its the left pod. The right one charges normally. So my left on is dead and my right one will down to say 35%. I then pop the right pod in and it charges normally.
Of course at the time in writing this on the forum I have case plugged into a 3rd party AirPods case and Apple Watch charger and and its charging! Okay this is good!
Simple question. Is this 3rd party case the same one which is showing the original problem? Or do you have 2 charging cases maybe this and the original Apple case??
I just noticed something. The case sits vertical on the charging stand. I have the cover open, so you can see the tops of the AirPods. Next it is my iPad with the battery status displayed. Attached are two images. The image with the left pod at 79% and the black lighting bolt icon is with the cover of the case open. The other image with the left showing 78% charge and NO lighting bolt icon is with the cover closed. Ain't that weird?!
This seems simple on the face of it, but I'm having to guess a few details probably because of software differences. Your first picture shows the left pod is removed from the case (no lightning flash, no charging) and the right pod is in the case but fully charged (green flash).
The second picture I don't see with my gadgets. It might be because your iPad and mine are different models, or maybe because my charging case and both my pods are 100% charged. I can't get the black lightning flash but I suspect it means connected and not yet fully charged, where the green flash means connected and already full charge.
Going back to your original problem, if you get different charging results with the two cases, it would suggest a problem with the case which doesn't charge properly. Look for debris near the gold plated contacts in the bottom of each well of the charging case. Look carefully, and clean very carefully using Apple's advice in How to clean your AirPods, AirPods Pro, AirPods Max, and EarPods - Apple Support
Just to make it very clear, don't use hard or metallic tools to poke around the charging contacts. Metal objects can actually short circuit the charging circuit and may damage the case.
