Longer and smarter battery
This is quite simply Suunto 9’s biggest bragging right. Depending on the modes, it promises anywhere from 25 hours to 120 hours of battery life, which is fantastic for those long treks in the woods. There are three battery modes – Performance, Endurance and Ultra – to match your workout needs.
One of the best things is that the watch also sends automatic alerts when juice is running low, reminding you to recharge before the next activity. But that’s not all; should the battery run low during an activity, the watch automatically suggests a different battery mode to conserve power, thus enabling you to complete your workout without losing the last leg of the chronograph data.
