According to news on October 11, if we talk about the biggest shortcoming of the iPhone 15 series, there should be no problem with fast charging. It is really beaten by the Android camp.Although the entire iPhone 15 series uses USB-C interfaces and Apple has not imposed restrictions, fast charging is still stagnant. The maximum charging power of the new model is the same as that of the previous generation, up to 27W (9V/3A).

Of course, Apple is trying its best to "appease" Apple fans. When it recommends chargers, it also implicitly expresses that you can't use up the 30W charger, so...
Some bloggers tested the charger officially provided by Apple and found that the 20W power adapter is the most cost-effective official choice (the official website price is 149 yuan). The price difference with the 30W power adapter is 100 yuan, but the charging speed is only 10 minutes faster.
The test results of the iPhone 15 Pro Max show that the full charging time of the 20W charger is 2 hours and 21 minutes; the full charging time of the 30W charger is 2 hours and 11 minutes, which is only 10 minutes faster, and the difference between the two during the charging process is no more than 4%.
