Both drones have an identical Max Flight Time in their specs:
31 mins (measured while flying at 4.7 m/s in windless conditions)
The times you achieve ares going to vary with what you do on each flight.

Hello, there. Thank you for reaching out. Please know that these models have 31 minutes of flight time. Measured in a controlled test environment. Specific test conditions are as follows: flying forward at a constant speed of 17 kph in a windless laboratory environment, in photo mode (without photo-taking operation during flight), and from 100% battery level until 0%. Results may vary depending on the environment, actual use, and firmware version. I hope this information helps.
