Pick the Yoga 9i Gen 9 if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. Its strongest claims are claimed battery life, weight.
Both ship with comparable refresh rate, thunderbolt ports, backlit keyboard, so those specs do not separate the two — focus on the differences below.
