Long Haul Tips?

The longest flight I’ve done was JFK-LAX which took 6 hours in a headwind. I am thinking about doing a long haul flight such as LAX-NRT, and I’m wondering what precautions there are or any tips on what I should do to keep my phone from overheating, crashing, breaking, or my plane from running out of fuel. Any advice?

There’s quite a few topics around covering this. Here’s a start for you ;)
