How does this $600 HP laptop have better battery life than some of the newest models?

This ZDNET review evaluates the HP OmniBook 5 16-inch, noting excellent battery life, a comfortable full-sized keyboard with number pad, solid everyday performance from the Intel Core Ultra 7 255H, good webcam and audio, and a competitive $649 sale price. Trade-offs include a 300-nit 2K IPS display (with a pricier OLED upgrade), most ports placed on the right side, and limited suitability for gaming or demanding graphics, making it a strong midrange choice for students and professionals focused on productivity.
