It worked for me and my config at least, after trying out all the other recommendations found online which didn't help at all (not even moving up to 16.5).


I even replaced my 85% cap over heating battery for a new one (in retrospect I don't think that would have been necessary).


The fast battery drain came just after updating to 16.4 on my iPhone 12 mini.


I performed a back up of my iPhone, did a factory reset and restored from my back up. Except for banking connections which I had to re-establish, everything else came back just fine, including emails settings and Google Authenticator (which I had anyway backed-up just in case). Now my battery lasts the whole day and into the evening again...
