Then they will re-charge, emptying the battery in the case, so I will end up with a dead pair of AirPods after a couple of days in the pocket, not using them.
I guess their tolerances are too tight, hopefully something that will be fixed with AirPod Pro 2, it is a big annoyance.
Some times they will also not pick up that they are being put into my ears, so I have to put them back in the case a couple of times for them to react. Really annoying too.
