I have access to wifi at the college campus and turn it on... but the wifi drops when I move around going to my classes. So I usually just leave it off until I need it. I know that depending on the network and area, wifi is generally faster than a 4G connection. How does this impact battery life on my phone? I'm thinking it would run the battery down less if I left it on 4G and did not keep turning the wifi connection on and off.

4G/LTE data uses more battery power than WiFi. It doesn't really make a difference when it's just in standby. WiFi is typically faster, but not always. It depends on the WiFi network and the data speeds in your area. Do some speed tests on each and use whichever is faster. It's fine to disable WiFi when the signal is poor. I toggle it on and off at times. You might want to consider getting a small portable battery charger that you can keep in your backpack so you don't have to worry about the battery too much.
