The cool thing about it is that the Starship requires a bit of intuitive thinking. If you're departing from a regular temperature airport, delay the pitot heat until lined up. Heck, if you're flying on a clear Caribbean summer day, why not leave it off and save the filaments and prevent their MTBF to creep up.
For example, when I depart before sunrise from an airport, or from a small airport, I simulate the lack of a GPU. I also don't import plans. I always plan in the cockpit, in the CDU. If I follow the checklist to a tee, I can quickly drain the battery. So, to save the battery, I pull the circuit breakers of the PFD and ND on both sides. It makes quite a difference. Then, when the time is right in the sequence, I pop them back in one by one.
