I am in aircraft with 96%. The phones on airplane mode the entries time. 7.5 hours long flight. It’s 55% when I get off the plane.

Because the battery percentage in your screen is more of a factual guess of how much battery you have , its not 100% accurate, so by the time you are at 1% you could have a bit more , but the battery percentage on the screen will remain at 1%.

Plus you probably have your phone on power saving options and lower brightness by that time.

It is a psychological tactic employed by phone companies(and pretty much every other company that uses a rechargeable battery). They report the battery status relatively accurate until about 33%, and then the software manipulates the reading so that the final 1/3 takes much longer, even though the battery has much more charge.

Mine lasts >72 hours on a charge, and would be significantly longer if I wasn’t using the GPS app, so ~1 hour on 1% isn’t far off from expected.

There’s a psychological factor that when you’ve just waited for it to be fully charged, each drop seems like it’s negating some of that. But by the time it hits 30% or so, you already know it’s low and you’re thinking about how much longer it can last before you need to charge it again instead of how long you spent charging it.

Not sure what the official term for it is, but it’s the same with anything you get that’s new and pristine. The first few scratches/dents seem to ruin that newness but after awhile you no longer care about a few scratches or dents, you just wonder how much more you can get out of it before you have to replace it.
