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.
随着iOS 13.1的发布，原本许多可以达到苹果7.5瓦最大充电效率的无线充电头现在
都只能够以5瓦的功率来充电。
原本iPhone 11在iOS 13两小时可以充到80%，但在iOS 13.1两小时后只能充到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中发现问题仍然还在。根据内部消息说这项改变似乎是刻意的。
它们说："所有跟Qi 充电相容的厂商会见到7.5瓦的充电速度"
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.”
如果是为了保护消费者，这是合理的。
但事实上，符合Qi 认证的厂商还是只有5瓦的充电速度
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，所有从苹果店贩卖的充电头都可以用7.5瓦的速度。苹果称这个叫做
"苹果快速充电"，但这只是Qi无线充电的一个标准（其可以达到15瓦的充电速度）
所以苹果不应该用强迫任何符合Qi无线充电的认证用在苹果的MFi认证上。
如果这项改变是真的，那苹果的快充无线充电器价格就上涨了
心得：
保护消费者（X)
保护苹果获利（O）

一般的快充头不知道有没有影响

7.5W和5W比一样还是慢，要锁就锁吧

不重新定义无线充电 要怎么再赚一笔

昨天试了还是可以超过5W啊 到底？

充电盘一定是吃5W以上啊 问题是扣掉耗损就是5W

反正我没在用

https://i.imgur.com/1R1NdlZ.pngiPhone11原本两个小时80%更新完变成两个小时55%这样你跟我说5跟7.5没差ㄇ？

一样慢...18W有线充屌打而且无线充超级浪费能源

以后会不会有Qi for Apple认证呢www

所以之前在官网买7.5瓦充电盘的都是盘子吗

苹果真的很鸡掰...

看来我把iphone8锁在ios12是正确的

反正无线充电都很慢 拿来充airpods就好

最近看到狗肉有无线充电手机架不然在这之前觉得无线充电根本鸡肋

旧机不敢乱升ios，就怕被阴，拔了3d、限制无线充，厉害啦！朕想拿回来的，你们敢说啥！凸凸凸

表面上说安全，实际就是商业策略绑架消费行为，但还是会一堆果迷大声赞好说难道要出问题再来怪苹果吗？颗颗

就是要你从官网买的意思

拔3D TOUCH锁无线充电，真的很会

无线充完全没有吸引的点

老实说啦 超过5w的Qi充电盘大概都没过Qi的EPP认证，一般来说都只会过Qi的BPP认证（即5W)

who car

iphone电池衰退 就会降频变顿 也是同样道理阿有听过三星小米的电池衰退 就要强制降频变顿吗?

商人要赚钱啊 你各位果粉还是会买单啦

根本只是 苹果偷降频 让旧机变顿 被抓包了 随便唬弄的理由只有果粉会相信这种唬烂的理由啦 嘻嘻

纯评论无线充：用在手机根本没带大效益 倒是加速电池耗损

充电盘白买了 安全安你妈个苹果

那星巴克潮潮怎么办？文青的手机需要无线快速充电

7.5哪里快啊......插个18W才是快。还浪费能源。

对我来说5W 7.5W 10W都没差 反正就是随手摆在桌子就开始用电脑 手机就默默地在那边充电 不过出门我会带快充

隔壁无线都20w还在7.5w退到5w

要是原厂的有20W，副厂的5W，这样才合理吧

还好我出厂13 能10w
