I don't know why that would only affect my Pros but not my Gen 2's. Either case is fine when the pods are there inside them, and I can wirelessly charge my Pros normally. But if I got my Pros in my ears, within 1-2 hours I hear the 'your AirPods battery is dead' noise, but the music continues to play. But if I put the Pods back in the case, no light, nothing. If I take them out of the case without charging the case first, and put them in my ears a few minutes later, nothing happens. No 'bling!' noise, no playback. Almost like the case is needed to do the initial pairing to iPhone. Either that or when I hear the 'battery is dead' noise my case is in some kind of power reserve. It's only an issue with my Pros. I get 5-6 hours of playback which is more than enough most times, for other times I carry my Gen 2's with me as well. I think the battery in the Pro's case is just defunct. I can't find any replacement cases anywhere.
