Why does 1% battery last longer?
Battery remaining is pretty much just a guess. Your phone measures the voltage and makes a guess as to how much of power is left. If you rarely or never let your phone run all the way to where it cuts off from lack of power, it will slowly start measuring more and more inaccurately.
The Short Answer
Battery remaining is pretty much just a guess. Your phone measures the voltage and makes a guess as to how much of power is left. If you rarely or never let your phone run all the way to where it cuts off from lack of power, it will slowly start measuring more and more inaccurately. First it will think 1% remaining is empty. Then 2%, and so on. Eventually, it's estimate of remaining battery is significantly far from correct. When you finally let it run all the way to empty, it will seem to last longer. It thinks it's empty at 5%, so it's shows 1% remaining when you really have 5% remaining. Since it still has power, it still runs, but the estimate is wrong. Because of this, battery drain slows down as it nears empty.
