I never look at the little battery icon, it doesnt seem to convey useful information, I look at the voltage and the watt hours.
even then it does not let you know how much range you have. my bosch tells you how much range you have in any assist level and its pretty accurate usually you get a mile or two when it says zero unless the terrain changes a lot all the time like more hills then it may under report the range a bit.
