Several things can help. First, minimize the amount of usage above ~80 or 85 percent. Second, minimize the amount of usage below ~20 percent. Try not to get your battery too hot. In other words don't charge it while you are pushing it hard.
And the most important IMO is variety of charging and usage. Be inconsistent, don't always start or end charging at the same percentage point. Don't always use it on battery, and don't always use it plugged in. Start charging half way down sometimes, and other times stop charging half way up. Inconsistency is good for your battery.
