【Mac 小知識】一個小動作!教你檢查 MacBook 電池是否到了極限!

macbook-battery-limit_00

小編用了 MacBook Air 已經兩年,雖然未至於嚴重損壞,但電量似乎比兩年前不再耐用,電池用了兩年,質素始終會下降,如何可以知道自己 MacBook 的電池是否到了極限?



按實 Option 鍵再打開螢幕左上角的  選單,按「系統資訊……」。打開 MacBook Air 的視窗後按左邊的「電源」,你會看到「健康狀態資訊」中的「循環使用次數」,就可以看到你的 MacBook 電池「被完全充電」的次數。

看這些次數有什麼作用?MacBook 電池作為鋰充電池,充電次數有上限,超過上限之後,電池的實際容量會越來越少,這時候就會換電池了。蘋果的支援網站其實列出了過去眾多型號的 MacBook 電池, MacBook Pro(Early 2009)、MacBook Air (Late 2010) 、Retina MacBook 或以後的 MacBook 型號,充電循環上限固定為 1000 次,而較舊款的型號則為 500 次和 300 次。想知道,可參見下面的列表。
