On April 21, according to Macrumors, Apple released firmware updates for Magsafe external battery design. It is reported that new firmware can achieve up to 7.5W charging in the case of non-external power supply, above the previous 5W restrictions, this wave Apple directly The charging speed of Magsafe has increased by 50%, and it is true to "speed".
It is worth mentioning that new firmware is compatible with iPhone 12, iPhone 13 Series, iPhone 11 and older models, although there is wireless charge, it is not Magsafe, not compatible is also normal.
There is a small partner of the Magsafe external battery, just upgrade the firmware to version 2.7.b.0, you can get a 7.5W charging speed.There are two ways to update, one is to upgrade behind the iPhone, but this method has a long upgrade time, it takes about a week. Another method is to connect to the MAC or IPAD with a data cable. If you can update it in five minutes, there is no apple's full bucket or an old man's utility iPhone update is good.
Xiaolan learned that Apple Magsafe is launched in 2021, the official claims that the highest charge speed is up to 15W,However, many users can only find that only an external power supply can only achieve 15W power, usually 5W outdoors.
Magsafe external battery and the ordinary charging treasure on the market are different. Small thunder thinks that the external battery is to increase the iPhone in the outdoor life, and the charging treasure is only used for charging when the mobile phone is fast.This means that the Magsafe battery does not necessarily require high power, but the official Apple Magsafe battery supports 15W, not open to users, it is a bit not enough.
Besides, Apple's official Magsafe external battery price has come to 749 yuan, and most of the external batteries with Magsafe certified in the market are more than 100.When there is no external power supply, it is possible to provide wireless charging power of 5W or more. If Apple unspeuses the charging limit, it feels not as good as buying third parties.
Say, from the firmware upgrade method of Apple Magsafe external battery, the iPhone contact upgrade is much lower than the Mac / iPad wired update, which seems to be quite slow in implying that the speed of Magsafe transmits data is quite slow. Small thunder, the iPhone may skip USB-C in the future, cancel the data cable interface, and transfer data may change to wireless form, and now the magsafe update efficiency is so low, I really don't know how Apple is "polished".
