Hey there trystin193,
Thanks for reaching out to the Apple Support Communities. Just to clarify, do you have Auto-Brightness disabled in Settings > Accessibility > Display & Text Size? If not, check out the steps below for more information and how to disable this setting: Adjust the brightness and color temperature on your iPhone, iPad, or iPod touch - Apple Support
About brightness levels
iOS devices use an ambient light sensor to adjust brightness levels based on the light conditions around you. The sensor lowers brightness in dark locations and raises brightness in light locations. The auto-brightness feature is on by default.
When auto-brightness is on, you'll notice that the brightness slider on your device moves according to changing light conditions.
You can turn auto-brightness on or off in Settings > Accessibility > Display & Text Size. To reset the auto-brightness settings, turn off auto-brightness and then turn it back on.
Let us know if that's able to help.
Take care!
