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?

Answer 1

The laptop could give you an average charge rate to 100% indication, with each percentage progressing at the same rate. But if you unplug it before it reaches 100% then the indicator will have to change to the true percentage, so it can look like you’ve gained or lost a lot of percentage at once when you plug or unplug it while it needs a charge.
