MacBook 查看電池健康有三種方法。一是通過系統(tǒng)設(shè)置查看,打開“系統(tǒng)設(shè)置” → “電池” → 點擊“電池健康…”可查看循環(huán)次數(shù)和最大容量;二是使用終端命令,在“終端”輸入 pmset -g batt 可獲取實時電量、充電狀態(tài)等信息;三是借助第三方工具如 CoconutBattery 或 Battery Health,能顯示更多歷史記錄、電壓變化并支持導(dǎo)出報告。建議定期檢查電池狀態(tài)以便及時處理老化問題。
MacBook 的電池健康狀況直接影響使用時間和續(xù)航表現(xiàn),所以定期查看電池健康狀態(tài)其實挺有必要的。蘋果系統(tǒng)本身提供了一些方法,不需要額外裝軟件就能搞定。

如何在系統(tǒng)設(shè)置里查看電池健康
macOS 從 Mojave 開始就內(nèi)置了電池健康信息,位置在“系統(tǒng)設(shè)置”里面:

- 打開“系統(tǒng)設(shè)置” → “電池”
- 點擊“電池健康…”按鈕
- 這里能看到“循環(huán)次數(shù)”和“最大容量”
最大容量低于 80% 就說明電池已經(jīng)老化,可能要考慮更換了。循環(huán)次數(shù)這個數(shù)值也能幫你判斷是否還在保修范圍內(nèi)(一般不超過 1000 次)。
使用終端命令查看更詳細(xì)的信息
如果你對數(shù)據(jù)比較在意,或者想看看有沒有異常情況,可以用終端查出完整的電池報告:

- 打開“終端”
- 輸入:
pmset -g batt
- 回車后會顯示當(dāng)前電量、充電狀態(tài)以及電池的健康狀態(tài)
這個方法的好處是能快速看到實時數(shù)據(jù),比如當(dāng)前是否正在充電、剩余時間估算等。雖然不包含最大容量,但可以作為日常檢查的小工具。
第三方工具能提供更多細(xì)節(jié)
有些用戶希望看到更多歷史記錄或者圖表,這時候可以用一些第三方應(yīng)用,比如 CoconutBattery 或 Battery Health。
這些工具的優(yōu)點包括:
- 顯示設(shè)計容量 vs 當(dāng)前最大容量
- 查看放電次數(shù)和電壓變化
- 支持導(dǎo)出電池報告,方便給維修點參考
不過建議只從官網(wǎng)下載,避免安裝來源不明的軟件,影響系統(tǒng)安全。
基本上就這幾種方法。官方方式夠用,終端適合喜歡簡潔的人,第三方工具則適合想深挖電池狀態(tài)的用戶。幾個方法都不復(fù)雜,但很容易被忽略的是——經(jīng)??纯措姵貭顟B(tài),比等到明顯掉電再處理要強(qiáng)得多。
