Battery health dropping quickly – iPhone bought in April

On average, you can expect about a 1% decline in battery health per month on an iPhone 14. You bought your phone in April and it's now November, so you've had your phone at least 7 months. 93% battery health after 7 months is actually pretty much what you'd expect. Keep in mind that battery health decline is not linear. It can remain steady for a while, then drop a few points rapidly. It doesn't appear there's anything unusual going on with your iPhone. When the battery health dips to 80% in the future, it will then be time to pay Apple to replace the battery.

The 14 was superseded by 15 in sept 2023, Where did you buy it?

Ok if it drops to 79% before April 27 then Apple will provide a replacement battery. Other than that, nothing else can be done about it. The ageing will probably slow down.
