The new firmware of Apple’s MagSafe external battery supports 7.5W wireless charging
The new firmware of Apple’s MagSafe external battery supports 7.5W wireless charging, but the upgrade takes a week?
Among the many MagSafe accessories for iPhone, Apple’s official MagSafe Battery Pack is a very practical magnetic mobile power supply , but its actual use experience is average.
The biggest problem is that the charging speed is very slow, which is very ugly compared to Apple’s previous one.
A good hunchback Smart Battery Case is not the same thing, but what everyone didn’t expect is that this product can actually improve the charging speed through a firmware upgrade.
9to5Mac found from the product support page of Apple’s official website that the MagSafe Battery Pack can obtain 7.5W wireless charging power by upgrading the firmware to version 2.7, while the original maximum charging power is only 5W, which also causes many people to run high loads.
When the app is running, it may happen that the external battery of MagSafe may not be replenished as fast as the power consumption of the iPhone.
However, it is incredible to upgrade this new firmware. Apple said that after the MagSafe Battery Pack is magnetically attracted to the iPhone, it will automatically start to upgrade the new firmware, but it will take a week. The official website does say “one week”.
The guess is that the wireless connection channel used by the iPhone and the MagSafe Battery Pack for data exchange is too slow and can only transmit a little bit, but if you don’t have the spare time, you can Connect it to a Mac or iPad via a wired connection, and the firmware upgrade takes just 5 minutes.
Although the upgraded charging power is still a lot worse than other wireless charging starting at 15W, it is believed that it has greatly improved the problems of users complaining that the charging is too slow.
After all, it is just a charging baby. Of course, the price of Apple’s magnetic mobile power supply is still exaggerated, it is as high as 120 dollar, and most of the similar third-party products are only 40-45 dollar.
