標題[情報] iOS 13故意調降無線充電速度？

What ChargerLab found specifically was that with the launch of iOS 13.1 many
third-party wireless chargers rated at Apple’s 7.5W maximum wireless
charging speeds were now operating at 5W. As you might expect, this
lengthened wireless charging times substantially. For example, an iPhone 11
running iOS 13 would wirelessly charge to 80% in two hours but after
installing iOS 13.1 it only achieved a charge of 55% in the same time period.
That’s woefully slow.
隨著iOS 13.1的發布，原本許多可以達到蘋果7.5瓦最大充電效率的無線充電頭現在
都只能夠以5瓦的功率來充電。
原本iPhone 11在iOS 13兩小時可以充到80%，但在iOS 13.1兩小時後只能充到55%
The downgrade still exists in iOS 13.1.2 and, despite no official explanation
from Apple, AppleInsider learned from a source within the company that the
change is deliberate. “Any vendors who are fully compliant with the Qi
charging spec and all of our guidance will see 7.5W charging," said their
source.
在iOS 13.1.2中發現問題仍然還在。根據內部消息說這項改變似乎是刻意的。
它們說："所有跟Qi 充電相容的廠商會見到7.5瓦的充電速度"
As an attempt to protect customers, that would seem reasonable but
AppleInsider discovered: “the issue is more complicated. Manufacturers, who
spoke on condition of anonymity, said Apple has yet to give them any specific
direction. Also, that they have discovered being fully compliant with Qi
certification requirements does not appear to guarantee their products will
avoid the 5W cap.”
如果是為了保護消費者，這是合理的。
但事實上，符合Qi 認證的廠商還是只有5瓦的充電速度
And here’s where it gets worrying. ChargerLab’s tests found that all
wireless charging pads sold by Apple Stores still worked at 7.5W. Apple calls
this rate ‘Apple Fast Charging’ but it is actually just part of the Qi
wireless charging standard (which goes up to 15W in rival products) so Apple
shouldn’t be enforcing any sort of certification under its Apple MFi
Program. If that has changed, fast wireless charger prices look set to
increase for iPhone customers.
更神奇的是，所有從蘋果店販賣的充電頭都可以用7.5瓦的速度。蘋果稱這個叫做
"蘋果快速充電"，但這只是Qi無線充電的一個標準（其可以達到15瓦的充電速度）
所以蘋果不應該用強迫任何符合Qi無線充電的認證用在蘋果的MFi認證上。
如果這項改變是真的，那蘋果的快充無線充電器價格就上漲了
心得：
保護消費者（X)
保護蘋果獲利（O）
