Based on the latest sources obtained by GSMArena, it is stated that the iPhone 13 Pro Max can now charge a battery with a capacity of 4,373mAh from 0 to 100 percent in about 86 minutes. Using a test method carried out several times, a graph is shown showing the average charging speed for the iPhone 13 Pro Max from 0 to 100% is 86 minutes. To reach a percentage of 57%, the iPhone 13 Pro Max requires a charging time of 30 minutes which is quite fast when compared to the previous iPhone series. The same source also shows the charging speed for the regular iPhone 13 which takes 107 minutes to charge the 3,240 mAh battery from 0 to 100 percent. In addition, there is no significant difference when using a 30W and 20W adapter. Actually charging a smartphone battery with a duration of lesser than 2 hours is a good thing. But of course, there are many fans who want Apple to be able to bring fast charging technology to make charging even faster, similar to Android smartphone manufacturers who can now provide fast-charging up to 100W.
