1, Apple's fast charge protocol is the USB PD fast charge protocol, charging 30 minutes full of 50%, PD intelligent control in the near chargeWhen 80% full, enter the trickle charging, do not harm the battery.
2, Apple has fast charging, from 8 series to 12 series, all support USBPD fast charging protocol, higher support to 22W, charging speed can be close to three times the standard, support Apple4A fast charging protocol, higher 12W, charging speed can be close to twice the standard.
3, -USB DCP: This is the most basic charging protocol, usually used with the standard 5W charger, charging speed is relatively slow. - APPLE 4A: This deal starts with the iPhone 6SThe maximum power supported is 12W, which is commonly used in third-party charging accessories. - USB PD: As the main protocol for fast charging of iPhone XS Max, it can provide more than 20W maximum power by using USB-C to Lightning fast charging cable.
4, iPhone XS Max compatible with three charging protocols: USB DCP, APPLE 4A and USB PD. USB DCP is the basic charging protocol, such as the standard 5W charger, although the threshold is low, but the charging speed is slow. APPLE 4Make the Apple phone heat, if coupled with fast charging, the phone will produce more heat, so there is a certain danger, so, the Apple phone generally do not charge fast, do not use wireless charging, wireless charging is just a empty function, not very practical.
The iPhone also has a fast charging function. At present, Apple supports PD fast charge technology, the maximum power can reach 20W, but it needs to be used with the official fast charge head. It is worth noting that when the phone power reaches 80%, Apple will automatically switch to the ordinary charging mode, no longer fast charging. In addition, Apple also supports wireless chargingHowever, the maximum speed of wireless charging is limited to 15W, which is slightly inferior compared to wired fast charging.
Easy to use The MagSafe charger can be magnetically attached to the magnetic ring on the back of the iPhone device, without the need to plug in the data interface, easy to use, and drive high. MagSafe charger wireless charging speed is relatively fast, up to 15W fast charge, compared to the previous 7W Qi wireless charging, the speed is much faster, the fastest can be filled with nearly 50% of the electricity in 30 minutes.
Wireless fast charge is neither fast nor slow. Wireless fast charge than wireless noFast charge is much faster, slower than wired fast charge. The power that the charging head wired outputs to the wireless fast charge base is not the wireless fast charge output power but the wireless fast charge input power. Charging time of more than 2 hours of wireless fast charge, not as fast as the wired fast charge of 1 hour and 30 minutes, is not fast charge. Unexpectedly, the wireless fast charging efficiency of 60% when the 18W is charged for 2 and a half hours.
Apple Wireless Fast Charge protocol updated in the Apple Store. Open the phone store, find someone. findApple Protocol, click to check for updates. Follow the system to update.
In the details of the iOS 13 system update, Apple officially stated that it solved the problem that the charging speed of some wireless chargers may be slower than expected. In addition, from some third-party measurements, Apple did restore the 5W wireless charging level in iOS 13. Users who want to try it out can upgrade their iPhone to this latest version (click here to see how to upgrade).
More in-depth testing also found that the wireless charging power is based on the wireless chargerThe use of Apple's official recommended wireless chargers, such as Anker, mophie, Logitech and other chargers using the "fixed-frequency voltage regulation architecture" architecture (this architecture is relatively safer and more stable), can achieve 5W wireless charging. In contrast, this year Apple also added PD fast charging function on the new device, and wireless charging even with Apple's official certification charging board, the maximum publicity efficiency is only 5W, in the face of competitors Samsung 15W wireless fast charging directly less than half, not to mention the cable fast charging technology of more than 18W at every turn.
1, cause: The system program has a problem, resulting in the charging function of the hardware is not normal, it is recommended to restore the phone can be used normally.
2, just put the iphone apple watch and airpods on the charging pillow, you can charge them wirelessly 5. According to Apple's official data, the iphone x supports qi standard wireless charging, while supporting fast charging for the first time, 30 minutesUp to 50% charge.
3, if your phone is updated to ios13 after there is no automatic shutdown, then there is no frequency reduction switch, the default is to turn off the frequency reduction. This option appears only when automatic shutdown occurs, and you can turn it off manually.
