The iPhone 14 Pro Max can charge at 14.5V, but doesn't perform as well at 9V
Oct 17, 2022| The iPhone 14 Pro Max can charge at 14.5V, but doesn't perform as well at 9V
In previous tests, it was found that the original 29W charger can still charge the iPhone 14 Pro Max, and the 29W charger has the voltage range of 14.5V2A and 5.2V2.4A, while the iPhone 14 Pro Max must hold the voltage range of 14.5V when using the 29W charger for fast charging.
After comparing the temperature performance of the two types of voltages, it can be found that at the time point of half an hour of charging, the temperature under the 14.5V voltage is about 1.7℃ higher than that under the 9V voltage, and the temperature difference with the standing time is 9.4℃ and 13.7℃ respectively. Because Apple has always used a switch charging solution, the phone will perform better than a 9V charge with this higher voltage and greater differential pressure input.
Overall, Apple seems to have adjusted its own chargers, charging, temperature performance in the actual perception is not obvious difference; In the actual charging experience, there is no significant difference in the charging time between the two chargers. At trickle charge, the temperature is almost the same, but as a result, the phone's battery will decay faster.
