batteries
$begingroup$ You''re probably confusing what "last longer" means. You will only get 80% of energy per charge cycle, but that cycle will "damage" your battery 5x less than charging it to 100%.So in far future, you get 5x 80% = 400%, instead of 1x 100% = 100% of the power. In other words, you will be able to charge the battery many more …
