Gaming laptop battery life is, by and large, rubbish. Or rather, trying to use a gaming-capable machine for a full day of work without charging it is, err, rubbish. I've hauled many discrete GPU-equipped lappys into the office for a spot of real-world testing, and most of them are usually begging to be plugged into a wall socket by lunchtime.
Upon hearing Intel's battery life efficiency claims for its new, Panther Lake-based, Core Ultra Series 3 chips, I knew what needed to be done. Top up my Asus Zenbook Duo review sample overnight, take it on my round trip from my Southampton home to PC Gamer Towers in Bath (a roughly 126 mile jaunt), use it for a regular day, and record when it conks out.
