Why does a laptop say it’s at 6-8% charge, and then it dies, but when it’s at a higher charge, going from 60% to 59% takes a while?

It seems there are a lot of detailed explanations. Here’s the simplest I can think of it.
A battery is like a tank of water, you can suction out the water at one end and for a brief moment (Longer in batteries) the water level is lower on that end, and must settle to get an accurate reading on the water level across the entire tank.
In a battery, it’s very similar but much slower, so realistically there’s no real way to tell how much battery life is left. The reason it jumps so much is things that read the level are mostly guessing.
However, it’s in my personal theory, that for the energy in a battery to “Settle,” is near impossible, because batteries do slowly leak their charge. While we can get good estimates based on voltages, they can be easily thrown off or wrong.
