Why does my controller suddenly only work if it has batteries and plugged in and it’s...

If any electrical device even a controller is getting extremely hot you need to unplug it and remove the batteries immediately as there is likely a short circuit inside they can start a fire. You need to throw the controller away and replace it

I don't think you understand what the problem is. Batteries aren't the issue. My controller works fine with my batteries. The issue is, as soon as I plug a USB cable and connect it with the console, the battery level suddenly changes to critical. That's
why I'm not able to update my controller WITH the controller plugged into the console. I have no battery issues whatsoever in normal gameplay.

Yes. I tried my headset in my phone. Sound is clear and my mic works. But when plugged into controller its like my controller does not recognize it's plugged in. My controller has fresh batteries and is up to date. It worked fine Wednesday. But when i played
Thursday it didn't work at all.

the battery pack fits as in clips in but it seems as if the controller does not recognise it as a battery pack (i mean the controller what came with the slim). the battery pack works fine as i have tried it on a older controller (a controller from my previous
console but one i brought like 2 months ago). the battery does not power the controller nore does it get charged by the controller when the cable is plugged in. the charge cable fits in fine and powers the controller when it is plugged in. there is nothing
wrong with the battery or cable it is the new controller what has been made not to fit the old battery pack so Microsoft make more money as you have to buy a new charge kit. its a robbery unless its my new controller what is not working properly then i will
more then happily send it away to get repaired with no expense from me as it has never worked from the start and do not believe i should pay for something to be fixed what was broke when it was shipped in that condition.

I think it's an issue with the new controllers for some reason. My Series X controller will freeze once a week or so (always when I'm in the middle of a race unsurprisingly!!)....I'll be driving and my car will suddenly just veer off the road and then be constantly accelerating. Only resets when I remove the battery from it. This is on the Series X so may not be the same of course.

Having said that, it has only happened with the Plug and Play Battery...never happened with normal rechargeables.
