The image is from GSM Arena. The phone Infinix has only 45W charge capability yet it does slightly faster than two other phones with much faster charging rates(and same battery capacity).
I know some phones throttle charging speeds but that is usually post 80% threshold. Why the discrepancy then?
Capacity and changing speed are two different things. I know from lipo cells used in Rx models that discharge speed is given in C which is derived from the max charge current per cell IRK. This Indicates that you can charge a battery with two cells faster. Given a good battery management system of course.
