Full Charging Test for iPhone 14 Series Phones

20W iPhone Charger Full Charging Test



Using the 20W charger to charge 4 phones and plotting the charging time as a line graph, we can see that the charging time is reduced by about 2 hours.

The difference with the charging time of the 18W charger is only about 10 minutes, which is not obvious to the user when actually using it.

29W iPhone Charger Full Charging Test

Apple has released a MacBook notebook with a 29W charger, and the 29W charger is at 14.5V 2A. Four phones were charged with the 29W charger, and the charging time was plotted as a line graph.

You can see no significant change in charging elapsed time from the 18W and 20W charger charging tests; 

And during the first 1 hour (0-80%) of charging, the 29W charger is significantly faster, with all charging over 55% for half an hour and over 82% for 1 hour.
