No, youre not doing anything wrong.
The ‘range’ figure quoted is not very accurate, and is known on here as the ‘guessometer’ as it generally bears no resemblance to reality. It attempts to use your previous trips to estimate how far you will get if you continue to drive in exactly the same fashion, but if you drive in a different manner to what it expects then the quoted figure will be off.
You’d be better off monitoring your actual range covered, rather than worrying about what the guessometer predicts.
You also need to bear in mind that the quoted maximum range of 32-33 is only ever possible in very friendly, ideal conditions. In the real world, a maximum range of around 25 miles is more realistic, and in winter that will drop to closer to 20.
Also remember that the default for the car is to generally use up all battery first before switching to petrol, so you shouldn’t need to worry about pressing buttons if your journeys can all be achieved on battery only. And there’s nothing wrong with arriving home with empty battery, that’s actually what you should be trying to achieve as its more efficient to run the car on battery than it is on petrol.
There are lots of different schools of thoughts about what buttons to press and when, but to be honest you can forget all that and just drive the car without doing anything. Once you get more familiar you might want to experiment with different strategies, but they will only ever make a relatively modest improvement to your efficiency.
