Why is snapchat draining my iPhone battery?

I have an iPhone 5c and the batter drains like crazy. It lasts only 2 hours at the most if I'm lucky. I looked at my battery usage and snapchat takes up 60% of my battery usage. Is there a way I can lower that? It also takes up a lot of space. Why?

Put your phone on airplane mode. It will charge super fast.

IPhones suck ***. Get an android if you're going to complain about battery life. S6 Edge has nearly another hour-2 hours more battery

Yeah it does that just close it
