Kburke582, we are glad to see that you've received a replacement phone and I know how challenging it can be if the battery life is not meeting your expectations. Help is here. How do you use your phone? Have you recently changed your phone usage habits? Please follow these steps to confirm the Maximum Capacity of your phone: Settings > Battery > Battery Health. As the description confirms, lower capacity may result in fewer hours of battery life. For your convenience, I have also included the following resource for iPhone Battery and Performance here: https://support.apple.com/en-us/HT208387 Let us know if this information is helpful.
