mac下运行ioreg -rn AppleSmartBattery | grep -i capacity
可以得到：
XML/HTML代码
- "AppleRawCurrentCapacity" = 6392
- "AppleRawMaxCapacity" = 6452
- "MaxCapacity" = 6452
- "CurrentCapacity" = 6392
- "LegacyBatteryInfo" = {"Amperage"=18446744073709551590,"Flags"=5,"Capacity"=6452,"Current"=6392,"Voltage"=12923,"Cycle Count"=94}
- "DesignCapacity" = 7336
- "BatteryData" = {"StateOfCharge"=100,"PMUConfigured"=0,"Voltage"=12930,"QmaxCell1"=7165,"AdapterPower"=1109165984,"SystemPower"=1108102207,"ResScale"=220,"QmaxCell2"=7161,"QmaxCell0"=7192,"CycleCount"=94,"DesignCapacity"=7336}
设计容量 7336，现在只有 6392了。。。2年不到，掉了1000了。。。不知道还能再战多久
