Hi we04ndy,
Thanks for using Apple Support Communities. Since your iPhone battery is discharging quicker than expected, we'd recommend starting by checking your battery's maximum capacity. If it is below 80%, it is time for a replacement. The following section of iPhone Battery and Performance - Apple Support explains this further.
"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."
If your iPhone's battery health is over 80%, there might be a setting or app that's using more battery than expected. Use the tips from Batteries - Maximizing Performance - Apple to help identify and resolve any issues. For instance, you can learn a lot from your battery usage. "With iOS, you can easily manage your device’s battery life, because you can see the proportion of your battery used by each app (unless the device is charging). To view your usage, go to Settings > Battery."
All the best.
