To put it bluntly, it is in terms of fast charging. Apple's fast charge has always been lame. My friend has used 120W fast charge, and the apple has only accelerated from 5W to 20W. In terms of charging, Apple has been vomited by users and thinks that Apple's charging technology is not good.
It is not difficult for Apple to do fast charging, and there are two main reasons for conservatism. The first reason is for profit. According to the current situation, Apple does not need to compare with others at all, nor will it shake its position. On the contrary, if there is something wrong with the battery, it will cause heavy losses. After all, Samsung once withdrew from the China market because of batteries.
On the other hand, in order to protect the battery, fast charging is convenient, but it will have a huge impact on the battery. Android manufacturers are afraid to publish battery health status, because if users see the degree of battery wear, they will really be complained. It is also very important that the service life of Apple's mobile phone can be so long.
Generally speaking, it has advantages and disadvantages to charge this thing quickly. In the final analysis, the competition in the domestic market is too fierce now, and manufacturers have to stack the configuration to make the parameters look good. However, the current mobile phone is basically changed after two or three years of use, so there is no need to entangle this issue.
