How to minimize data usage?

Hi HiCaptEd,

Thanks for reaching out to Apple Support Communities. It sounds like you have a question about data usage. We're happy to provide some information to assist.

You can control which apps on your iPhone use cellular data. Start by navigating to Settings > Cellular or Settings > Mobile Data. The article here has helpful visuals and information as well: Use cellular data on your iPhone

We'd also recommend checking to see if Wi-Fi Assist is turned on as this will use cellular data when your Wi-Fi connection is poor. Check out the article here for more details: About Wi-Fi Assist

Additionally, we'd recommend checking into the Background App Refresh in Settings > General > Background App Refresh. The bottom of the article here has more information and a helpful visual: Switch apps on your iPhone, iPad, or iPod touch

Cheers!
