iPhone 6(S)/Plus What is the optimal battery health maximum capacity?

iPhone 6S. Battery timing started to suck since I upgraded to iOS 11. I am thinking about replacing the battery but I want to make sure if the condition does warrant a replacement. The Battery Health Maximum Capacity is showing to be 82%. Should I replace?

At this stage of the game if you’re going to keep the phone or sell it, I’d replace the battery if it showed anything under 90%..

 

[now i see it]

80% capacity is considered replacement time.
