using other devices instead my iPhone for everything?

I’m curious how much charge I could save on my iPhone if I didn’t rely on it for everything. I might charge my iPod later to use that for music. That along with using my real camera over the iPhone one… hmm 🤔

Realistically, I won’t use the iPod instead of my iPhone bc you need to have songs on it before, but I’m already using my Canon PowerShot camera instead of my iPhone camera in most cases, so we’ll see!
