Welcome back to Thermal Paste Diaries, I am Mackenzie Dupuis. This week is about the handheld in your bag and the question everybody asks me: why does it die before the flight even takes off? I took four current handheld gaming devices, ran the same three games at the same brightness, and logged every minute until each one shut down. Some of the numbers surprised me. One device lasted twice as long as another in the exact same game, and the reason is not the battery size. I will explain what actually drains them, which settings matter and which are placebo, and the four changes that nearly doubled my play time. You are listening on Witspeak Podcasts. Charge up and let's go.
