Did they definitely replace the battery?
I took in my iPhone 6S to the apple store for battery replacement today.
I handed my phone to them with about 23% battery charge.
I received it back with 26% battery charge which seemed rather odd, the assistant did not know why but said it was fine.
I checked the Battery Health (beta) and it says "Maximum Capacity 100%"
Does this mean they definitely changed the battery? or can they just reset the battery statistics so it says "Maximum Capacity 100%"
My battery wasn't completely shot before so I'm not sure whether it will be obvious to me just by using it.
