New hobby looking for a way to get longer flight time

I just purchased a drone model hc 677 gps drone looking for a way to get longer flight time. What can I do.

If it doesn’t take proprietary batteries, you could put in bigger ones, but it looks more like a toy/recording drone, so I don’t know if it can take different batteries

what are proprietary batteries

Batteries that are restricted to one or more models/brands/series. For example, a DJI Mavic battery won’t work with a DJI Tello, and vice versa. If the drone of yours has a custom shaped or somehow differentiated from normal “naked” batteries, you’re pretty much stuck with that one battery
