"However, according to reports, Xiaomi's 120-watt charger actually "only" delivers 80 watts"
What is your input power?

Glad to see someone solved a problem that was not a problem. Phone manufacturers are great at that.

Indeed. After 18W-25W which really speeds up the slow 10W charging, further fast charging (45W-120W) becomes a tradeoff between battery health vs time spent on charging. I think 45 mins to even 1 hour is acceptable time during which I can live without my phone and it charges.

Pumping that much current at such high voltage so fast is sure to degrade the battery quickly.

Truly amazing numbers..but what about some independent tests regarding battery degradation over time, compared to say, a battery that is charged at 30 Watts ?
A lot of us would like to use an expensive phone like that for over 2 years..and some of us as long as 4 years..
