WF-1000XM4 Low left earbud battery?

[AdyKing]

I've been having problems with my wf-1000xm4's.   The left ear bud battery runs down considerably faster than the right. 
I'm aware one does more work than the other but from a full charge I'm getting maybe 2 hours before the low battery warning, left bud 20%, right bud 84%.

I've cleaned all the connections although it's charging ok, just running out fast.  Anyone know of a fix?

Similar issue, however, with the right WF-1000XM4 being completely dead. The left may have up to 100%. Buds are no longer pairing with my phone. Unable to connect with the app, or Bluetooth. Very frustrating..!
