Charging time of lithium ion batteries
Your cell is not charging more quickly than normal. Rather, the other battery in your graph is charging much more slowly than normal because it has high internal resistance so quickly reaches the CV = Constant Voltage phase, which means that the charge time will increase because more time is spent in the CV phase (at lower charge current).

Below is typical CC,CV charge for a similar capacity cell. Notice that the charge completes in 73 mins - close to the 80 mins of your 430mAh cell. Notice also that it stays in CC = Constant Current mode for 57 of 73 mins, about 79% of the charge, which is typical for a healthy cell.



Contrast that to the graph you supplied below, where the 1C charge quickly enters CV in about 12 mins of a 141 min charge, i.e. at about the 9% time mark. This is typical of a very unhealth cell with very high internal resistance.



The first graph is from the site lygte-info.dk, which has a large number of reviews of batteries and chargers. Perusing some of those should give you better intuition on typical (dis)charge curves.
