An article today said using your phone battery below 20% and charging it routinely above 80% reduces battery life…what causes this and is it the same process at both ends of the range?
In: Physics
Like your five? So batteries, all batteries work because the world is charged, either positive or negative. Batteries are arrange to store positive charges and “discharge” them to a negative, like a remote without power. Eventually a battery runs out of positive charge and both the battery and remote are negative. Adding positive back to the battery creates heat, mainly because nothing is perfect and some of the positive charge leaks away as heat. This heat slowly reduces a batteries ability to both discharge it’s positivity and receive that positivity until you get mad one day and replace your battery for a new one that isn’t worn out from the heat and the work it has done. So, directly answering your question around range. A battery doesn’t get as warm in the middle of it’s charge as it does when it’s out of positive charge or nearly full. #chemistry (another long explanation)
