I just upgraded from an S22+ to an S25+.  The staff member at the Verizon Wireless store did the transfer for me.  This is at least the third Samsung that I've bought from Verizon.  After conducting extensive research, I changed all the necessary and suggested settings in Notifications and Battary, and cleared the cache settings, both general and app-specific.  There are probably a couple other things that I've forgotten.  I'm at my wits' end.
