I can’t see my battery health.

iPhone 6 Plus, iOS 12
Battery health uses the battery's built in diagnostic. If it isn't reading (as yours isn't) that means either the battery has failed or an original Apple battery was replaced with a cheap knockoff. But it will only cost you $49 to replace the battery (assuming there is nothing else wrong with the phone).
Your iPhone 6 battery needs a checkup.
Make a genius bar appointment with Apple for an evaluation.
They have diagnostic tools and can tell you what options you have.
What I meant is that I can't see how many percentage in maximum capacity. See the attachment below.
Settings > Battery > Battery Health > here.
If you have an iPhone 6 Plus, maybe you need to replace the battery?
Even if you tap on the ">" symbol on the right side?
