For many of us our phone camera is the best we’ve ever owned and is usually our primary camera. The issue is fighting the urge to use it like we normally do. There’s a chance that your service will still work and that’s a shame in some ways. Once you get past the constant urge to check for notifications leaving it off for days at a time can be a real relief. If you do want to use it as a camera and not be distracted you can turn it on airplane mode. The battery life will likely be doubled or tripled. Or you could bring a point-and-shoot camera.
