2018 年 9 月入手的 MBP，看了下电池损耗情况
ioreg -rn AppleSmartBattery | grep -I capacity

"AppleRawCurrentCapacity" = 4337
"AppleRawMaxCapacity" = 4371
"MaxCapacity" = 4371
"CurrentCapacity" = 4337
"DesignCapacity" = 5088

DesignCapacity，5088 是设计最大电池容量了，目前电池实际容量是哪个，数据上看有两个，4337 和 4371 。

电池循环次数 307，大家的机器怎么样了。

算一算，电池损耗超过了 24%。。。。

"AppleRawCurrentCapacity" = 2472
"AppleRawMaxCapacity" = 4098
"CycleCount"=330
"DesignCapacity"=4790

MacbookPro 2017 w/o touchbar.

AppleRawCurrentCapacity 是此时电脑电量
AppleRawMaxCapacity 是电脑最大电量
DesignCapacity 是出厂最大电量

快整三年了，损耗了(4790-4098)/4790=15%，平时正常使用，还行吧。

翻到了一张 10.9 号的截图，发现当时的电池容量是 5846，183 次循环，
也就是说，20 天掉了 300mAh 。4%的损耗。。。

@ttys001 3 年的损耗跟我两年一样啊，差别还真是挺大的。

macOS 最新出了类似 iOS 的电池保护功能，但是逻辑和 iOS 上有时候只充到 80%不同，似乎是直接把电池容量在底层数值缩小一点来避免充满。偏好设置电源里有相关选项，你看看你的设置如果是开着的话，试试关掉，看看容量会不会变多。

以上都是我的猜测，没有验证过😁。

垃圾的一匹，我 2020 年 1 月份的，电池只有百分之八十几了。
