Using the parking lot analogy (you can find a parking space quickly when the lot is half full vs having a difficult time finding an empty spot when it is 95%) - I heard that charging a battery from 80-100% stresses the battery the same amount as when you charge 0-80%. In other words, that last 20% top off to 100 takes the same amount of time and energy as the first 80%.
So if you top off 20% twice (pretend two nights in a row) - you get a total of 40% charge. While going 0-80% two nights in a row is 160%.
Do you get "more for your money" simply charging from 0-80% thereby extending the life of the battery? I know official Apple paperworks says it is best to charge to 80%, but is this the actual reason?
