Phoned battery health dial codes

[1tooth]

Used phones around tukcom, usually have their battery health displayed. My Galaxy Note 20 seems to be getting hot recently. A sign of declining battery health. Does anybody know the short code to check battery health?

I asked Google re my iPhone: advised check >Settings>Battery.

My battery showed as 85% of new capacity, in good health.
