Battery performance
Uhmmm my iPhone 6’s battery’s maximum capacity is at 100% but it drains so fast. What should I do?
iPhone 6, iOS 12
iOS can display the percentage incorrectly.
How old is your iPhone?

If your iPhone 6S has the original battery and it's showing 100% battery health, I'd agree with sergekills that your phone is displaying something wrong.
