My wife had the battery for her 6s replaced by Apple around 5-6 months ago and it’s already down the 83% health. I’m going to contact Apple in a few days but wondered if anyone has seen similar? Surely it shouldn’t already have diminished that quickly?

Definitely contact Apple. The battery shouldn't lose capacity that quickly. I would expect maybe 8-10% in a year, depending on how heavy the usage is.

How many percent of the battery does she use in a day? In my last 10 days, I've only exceeded 100% one time. I was in the 90% range 3 times. The other six days averaged about 60%.

My battery is at 99% after about 3 months.

How many charge cycles are on the replacement battery?

Had my 6S battery replaced Nov 1st. It remains at 100% fortunately according to Coconut Battery app.

I had my 6S’s battery replaced in the fall. It died completely 2 weeks ago, and I replaced my iPhone. I miss that 6S and Touch ID.
