我用了个 gnome 插件 Vitals 电量里能看到 capacity 但经常飘忽不定在 80 多到 96 之间徘徊才用了一年的电池
有什么比较准确查看电池健康度的方式吗

```
cat /sys/class/power_supply/电池名称/energy_full # 查看当前最大容量
cat /sys/class/power_supply/电池名称/energy_full_design # 查看设计时的最大容量
```

大概是掉到 80%开始充电，充到 96%停止。

读取的是电池报告的容量, 如果电池固件不行那就不准

@LiangBryan 从数字上看 Vitals 读的就是这个那可能还是和底层固件相关了
