14.5V charging for iPhone 14 series? Yes, but not recommended
Oct 10, 2022| 14.5V charging for iPhone 14 series? Yes, but not recommended
From the first iPhone 8 to support USB PD fast charging to the just-released iPhone 14 series, Apple's fast charging design is arguably almost the same, with a switch charging scheme and up to 17V input. The charger has 9V voltage range is the best choice, if there is no 9V voltage range, then choose other voltage than higher, here also involves the iPhone handshake PDO2 voltage range knowledge, interested in Xiaobian later another article introduced.
From the actual comparison test, you can see that the speed of using the 14.5V2A charger increased by less than 2%, but the temperature rose by nearly 2 degrees, the hottest part of the back cover reached 46 degrees. You should know that the charging temperature of Android phones with 100W+ charge pump solution is not as high as 46 degrees, so the switch charging solution is an unreliable way to charge the iPhone with 14.5V high voltage. Apple does not recommend this charging method, it is just a "safe range upper limit" support.
iPhone in the face of higher voltage, voltage difference is larger power input, mobile phone is bound to charge more hot than 9V, user experience decline, battery decay rate is faster, you should avoid the lack of 9V voltage of the "defect" charger.
