Re: [討論] iPhone 12 mini 用 MagSafe 充電為 1

[frank0425w (為什麼要取法蘭克)]

簡單幫忙整理一下

1. 蘋果表示MagSafe的無線充電在iPhone 12 Mini上最多只有12W，而其他12系列機型都有
15W。

2. 在使用無線充電時，充電的功率會被很多因素影響，包含不同的變壓插頭、充電時使用
iPhone的lightning接口（例如lightning耳機），使用lightning接口時充電功率會從15/
12W變成7.5W。

3. 使用MagSafe充電前記得要先插上MagSafe的電源再放上iPhone，不然一樣會被限制充電
效率。

: 嗯？是因為無線充電的影響嗎？
: 不過電池小電量小，這樣應該也還行吧。
