    不知从哪里听到锂电池过饱和或者过度放电都不好。但是在公司经常会遇到以下这种情况:
    带着笔记本开个会, 回到工位。电量并非 95%以上,怎么办,插还是不插充电?

    • 土豪请走开。一年一换不用纠结。
    • 无所谓党请走开。坏了就换。
    • 好奇党,强迫症同学请继续。

    让我告诉你,这个问题不需要纠结。
    直接插上,让电脑使用电源,但是充电。
    这一切不需要预约天才吧,不需要购买官方设备。
    你在办公室自己动手可以搞定。

    材料:

    mac 笔记本适配器 (必须)
    笔记本 (可无)
    剪刀 (可无)

    步骤:

    照着下面的图操作

    何必?系统本来就会控制是否充电。

    > The charge extremes can vary, but typically they are between 0% - 20%, and 90% - 100%. This means that when a MacBook battery is between those ranges of percentages, it will degrade faster than normal.
    所以楼主你是对的,电量过饱或者过低都不好

    > Will my battery overcharge if left plugged in?
    > The harm doesn't come from overcharging the battery. This does not happen as the battery controller chip inside of the MacBook Pro and Air are intelligent, and stop the battery from charging past the overcharging safety threshold.
    但是楼主的这种做法也是没必要的。充满了后电池控制程序会自动停止充电。

    已知:
    1. 电量 95%以下系统会自动充电。
    2. 大于 90%,过饱和不好。
    求解:
    怎么控制在 90%一下?
