Thanks for reaching out, Osmanch1.
It sounds like you have some concerns about your iPhone battery's health. We can definitely help.
When it comes to battery health, it is important to remember that batteries work due to a chemical reaction that takes place inside the battery and that eventually all batteries are consumed and need to be replaced. That said, your iPhone battery is designed to last over 500 complete charging cycles before dropping below 80% health and needing replacement. A charging cycle is a full charge from 0% to 100%, or multiple equivalent charges, such as from 50% to 100% twice.
How long this takes will depend on your usage and charging habits, enviromental factors, and more. A great guide that you can check out is iPhone Battery and Performance which goes into more detail. We don't think a drop to 93% is unusual for about a year of use, but you can follow these steps Maximizing Battery Life and Lifespan if you'd like to get more out of your battery.
Hope that helps!
Take care.
