I’ve got an iPhone 6s and the year of apple warranty will run out on May 26th.

During the first 7 or 8 months, since I bought the phone new, my battery health was going down gradually as intended (I use the phone a lot), 1% or 2% at a time.

Since about 5 months the battery health is stuck at 86%.

Apple says that if in the first year your battery health goes below 80% they’ll replace the battery for free.

Is there any known way to refresh the reading? Other than factory reset

My battery is clearly behaving like a sub 80% health battery but I need the readings update for the free swap
