    Can anyone tell me what is meant by "Battery health 67%"?

    Does this mean that my battery only holds 67% of the charge it could?

    It's had 300+ cycles, by the way!

    Thanks for reading.

    Yes, that's exactly what it means. Take the original spec in mAh and multiply that by 0.67. This is the amount power that your battery can hold/provide.
