Bluetooth connection dropping

The iPad 7 battery is indeed weak therefore I keep it plugged in at all times. I have tried moving it closer to the speaker but that didn’t help. The modem, router, speaker & iPad are always within 14’ of each other as I live in a small home. Compatibility is something I don’t have information on except to say I had been using them for over a year before this problem started happening which was a couple of weeks ago. I searched to see if others had similar problems and found several who have and think it may have something to do with the last iOS update. In my case the problem began before I updated the iOS…updating it was one of the initial steps I took.
