What does it mean when my iPhone is taking a long time to charge to 100% charge but then when I look at my battery health is says 98% optimized does this mean my new 3 month old phone is not charing fully to 100%?

Hello rabeccafrommacomb,
Thank you for reaching out in Apple Support Communities. The Maximum Capacity for the battery health can decrease its percentage with how the settings for your iPhone is configured and the amount of time one uses the device. Here's more details:
Your battery's maximum capacity
The Battery Health screen includes information on maximum battery capacity and peak performance capability.
Maximum battery capacity measures the device battery capacity relative to when it was new. A battery will have lower capacity as the battery chemically ages which may result in fewer hours of usage between charges. Depending upon the length of time between when the iPhone was made and when it is activated, your battery capacity may show as slightly less than 100%.
A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions. The one-year warranty includes service coverage for a defective battery. If it is out of warranty, Apple offers battery service for a charge. Learn more about charge cycles.
As your battery health degrades, so can its ability to deliver peak performance. The Battery Health screen includes a section for Peak Performance Capability where the following messages may appear.
This information is outlined in this helpful article for further insight: iPhone Battery and Performance
If Optimized Battery Charging is turned on, this will help maximize the Maximum Capacity for the battery health. It can maximize the lifespan of the battery and that information is outlined here:
With iOS 13 and later, Optimized Battery Charging is designed to reduce the wear on your battery and improve its lifespan by reducing the time your iPhone spends fully charged.

Kind regards.
