What happens when you charge a battery to 85%?

For example, charging a battery to let’s say 85% will allow 2500 full charge-discharge cycles before capacity drops below 90% but if you charge to 100%, then the battery will take 1800 cycles before dropping below 90% capacity. Unfortunately, the answer is “it depends”.
