So I have a z fold 4 and I have a pair of airpods, and when my airpods are dead because I forget to charge them I use wireless powershare, and recently more specifically today powershare won't work, as I'm typing this my phone is at 84%. So pretty much what happens is that I turn on powershare I put my airpods case on the back in my phone and for a few seconds it starts charging then it just stops and I get the error "wireless powershare has stopped working, try removing anything thats between the 2 devices like a case" and yes I do have a case for my airpods case that I removed before charging and it still doesn't work, and before you ask yes it has worked before but I haven't had to use it in a long time.
If the wireless power share feature is still not working in Safe Mode, it is recommended to have the phone evaluated by a certified technician. You can use the following link to find a list of service centers in the U.S. that can do the repair: http://www.samsung.com/us/support/service/location
Also make sure that this placement of the AirPods is absolutely 100% dead on center of the back of the fold where the charger is like use a tape measure if you have to You need to get it within the exact millimeters for it to stay charging. Even when I try to power share to my Galaxy watch 5 Pro from my s22 Ultra, If I am one or 2 mm off center it will charge for like you said 2 seconds then stop charging and I literally can like blow on the watch and it'll start charging again It's absolutely crazy how dead on you need to be when you're reverse wireless charging something small. The only product I have that does not have this issue is my Galaxy buds 2 Pro, those I can pretty much throw onto the back of my phone and they can land anywhere near the middle of the back and they'll charge and stay charging but anything else needs to be to the exact millimeter center of the back of the phone that holds the wireless charging coil. But I do suggest you do the method I suggested as it sounds like a recent security patch or update kind of mess things up for you and this should fix anything software related that is stopping the charging if it is software related. If it's hardware like you are not getting a good connection for some reason then it will still do this problem after my software fix method if that's the case then I was going to have to say you are probably going to have to give up on the wireless charging AirPods through your fold 4. AirPods charging coils are so small that it's not even funny I think they're even smaller than my watch coils and iPhones have much larger charging coils in diameter then Samsung so much easier tolerances to do things like wireless charge or charger AirPods. By the way why the heck do you have AirPods if you have a fold? You traitor lol I'm just kidding bro but should have went with the buds 2 bro, They are literally the Samsung version of AirPods pros and match them feature for feature plus a little extra because Android allows extra things to happen compared to iOS maybe if you can't get it working and you absolutely rely on it as your method of charging, it might be wise to sell your AirPods as they retain value pretty well and use that money towards something Samsung if you're going to keep your Samsung phone or you could go and sell your fold which still has a decent value, nothing crazy anymore since the five came out but still sellable and buy an iPhone You just need something over a 12 and it'll have the mag safe and I think iPhone's have reverse charging? I'm not really sure I don't have an iPhone and haven't owned one except for the very first generation when I was a teenager so I have no clue if they reverse wireless charge but I assume they do so you could get an iPhone but it's just very atypical for someone to run a Samsung phone on iPhone headphones because you really can't use the maximum potential of either device when mixed together so it's not a great combination and they are both extremely expensive products so just a very unusual situation you're in. Anyways try my method and see if it fixes your problem hopefully you have some luck, if you can, go on Google and image search where the wireless charging coil is like a x-ray scan of the internals of the fold 4 Then use some tape or something small and adhesive to mark the exact center of that coil this way in the future you can just set the AirPods on that piece of tape and have no issues with lining it up perfectly since Samsung demands that you whip out your measuring tape and get it to the millimeter in the center for reliable reverse charging if it's not a phone or buds 2 Pro
