In the official introduction document of Apple (Apple lnc.)iPhone 15seriesmobile phoneOfWireless chargingElectricity introduction:iPhone 15seriesmobile phoneSupportableQi2Wireless chargingElectrical standards.The user can understand that throughQi2Even without Apple's "MFM" certification, third-party products can provide users with a 15W wireless fast charging experience comparable to MagSafe.
It integrates Apple's MPP (Magnetic Power Profile) technology, provides a better wireless charging user experience, and paves the way for the development of new features and enhanced functions in the future.
IOS 17.2 official upgrade
On the day of Double 12, Apple released the official version of iOS 17.2. Although there is no clear explanation, it is not clear that the iPhone 13, iPhone 14 seriesmobile phoneAlso increasedQi2Wireless charging support.At the same time, it can also be seen that this update has brought a new [Handwriting] APP, and enhanced the experience and functions of operating buttons and cameras, which requires users to experience on their own.
Actual measurement of Qi2 wireless charging
Previously, the charging head network had disassembled and analyzed many products with Qi2 certification, including horizontal and vertical products, all of which have fast charging modules supporting the QC/PD protocol, which can well meet the specification requirements of Qi2 MPP.
With the upgraded iOS 17.2 systemiPhone 15mobile phoneCarry out magnetic charging test. This Qi2 wireless charger is used formobile phoneDuring charging, the wireless charging UI animation is consistent with the original MagSafe charger;The measured output power of the charger is 8.91V 2.22A 19.75W.
Similarly,iPhone 15When the mobile phone is equipped with the original/"MFM" certified wireless charger, the output power of the charger can reach 9.02V 2.1A 18.91W.It can be seen that there is no obvious difference in charging power between the two wireless chargers.
Charging process
Let's seeiPhone 15Performance with Apple MagSafe wireless magnetic absorption charger.
After the power supply is connected, the 9V voltage is shook. The power is stable at about 18.7W in the first hour and 11 minutes;Then the power drops to about 13W and continues to charge to 57 minutes;Then the power drops again to about 7.6W and continues to charge until 1 hour and 23 minutes;Then the charging power enters the trickle charging mode and lasts until the end of charging. The whole charging process takes about 2 hours and 10 minutes.
After connecting the power supply, shake hands with 9V voltage, and the power is stable at about 19.5W in the first 9 minutes;Then the power drops to about 14W and continues to charge until the 32nd minute;Then the power drops to about 12W and continues to charge until the 45th minute;Then the power rises to about 15W and continues to charge until the 49th minute;Then the power drops to about 13W and continues to charge until 1h and 05min;Then the power drops to about 8W and continues to charge until the first hour and 32 minutes;Then the power drops continuously and enters the trickle charging mode until the phone is fully charged. The whole charging process takes about 2 hours and 2 minutes.
Temperature test
Place this Qi2 certified wireless charging module in a 25 ℃ incubator for iPhone 15 charging for one hour, and then collect the temperature of the charger surface.
The maximum temperature of the contact surface of the wireless charging module for iPhone 15 charged by the thermal imager is 42.9 ℃. Since the module is an engineering sample, the measured shell temperature is that the maximum temperature of the PCB board is higher than that of the original MagSafe charger.
Summary of charging head network
Based on this test, after upgrading the iOS 17.2 official version system, the wireless charging power of the iPhone 15 series mobile phone is equivalent to the experience of the original MagSafe charger for the Qi2 wireless charging product, and the product does not need to be certified as "MFM". Users who prefer wireless charging will have greater demand for such products. This time, with Apple's opening of MPP function,The long silent wireless charging market may once again have disruptive products.
