Regarding running watch credentials, the Apple Watch has taken huge strides forward since the first generation launched in 2015, almost a decade ago. It now offers some of the most reliable GPS, solid optical heart rate tracking, a much more capable native running app and plenty of third-party apps to beef up its running performance.
But despite improvements, there’s always been one thing holding it back – battery life. The Apple Watch Ultra hoped to change that, aiming to be the best Apple Watch yet. With 12 hours of GPS tracking power, the Apple Watch Ultra packs the biggest run-time battery life of any Apple wearable to date. It’s also the most rugged outdoor-proof Apple Watch yet.
