I've been doing 80% >> 45% for a while on a 14 pro max....on a best effort manual basis. Appears to be working...I'm on 93% battery health today while googling

I've been doing 80% >> 45% for a while on a 14 pro max....on a best effort manual basis. Appears to be working...I'm on 93% battery health today while googling suggests others where hitting <90% in mid 2023 already. So unscientifically it does seem to matter, though whether it is worth the hassle is another question
