Battery health only declines.

If you want 100% Battery Health, replace the battery.

Increasing the Battery Health:

No. You cannot increase not decrease the iPhone Battery Health yourself. In fact, the percentage can even increase. I've seen it myself. This is because the Battery Health is all just a guestimation on Apple's part.
