The Razer’s battery lasted for just over two and a half hours in the PC Mark 8 Home test. That’s a middling result for a gaming laptop, and almost on par with the PC Specialist. It’s better than the Strix Scar laptop, at least, but there’s no way that the Razer will last for a full day away from the mains – it’s definitely meant to be plugged in and left at a desk.
Battery life is even worse while playing games, as we found the Blade Pro lasted for just over an hour playing some 1080p titles. If you’re going to a LAN party, don’t forget your AC adapter.
