Charging watts on S20

[Thegreatone3]

Had some free time so compared charging power of last year's Adaptive Fast Charger (AFC) from my S10 with the 25W super fast charger (SFC) that came with the S20.

0-25%: AFC = 13.8W, SFC = 19.9W
25-65%: AFC = 13.8W, SFC = 15.2W
65-85%: AFC = 13.8W, SFC = 13.8W
85-90%: AFC = 12.6W, SFC = 12.6W
90-95%: AFC = 10.5W, SFC = 10.5W
95%: AFC = 8W, SFC = 8W

So the 25W charger gives you a nice advantage if you charge from dead a lot, a small advantage from 25-65%, and really nothing from 65% up.

Thank you for your research. I think it's a handy reference.
