this stated 30 min is on paper, but RL show ca 25min fligt time possible with draining battery pretty deep (to 5-10% capacity). remaining flight time is ussualy shown as time with current power draw. So if You flying really full throttle, it might be that it drops v. fast. (like in cars, drive ecofriendly, You can manage under 10l/100km efficiency, give it full throttle, and 40-50l/100km consumption is easy to achive )
quadcopters this type are most effective when flying "slowly" (around 30-40% power, but it's weight/motors/other factors dependant)
so a 5-6x flight time reduction (25min vs 5min) when giving full throttle vs. steady flight is IMHO still possible.
edit:
here a table for a 1404 BL motor (I think that mini2 have something similar in size, but diff KV/2S), but it's only to show how power draw drasticly changes on BL motors
in this example on 30-40%throttle usage would be under 2A (per motor), full throtle is even more then 6xtimes bigger draw. This 5-6 times flight time reduction can be real.
also mini1 got weaker motors, so drain there will be slower + liion vs. lipo battery discharge little different (more jumpy) + they might updated reading freq. >> it will give more acurate readings now...
