The Steam Deck's battery life has been a key topic of discussion both ahead of launch and once we actually got our hands on Valve's handheld gaming PC. And it was obviously a key topic for the designers when they were sketching out what they would be able to jam into the Deck. From talking with two of Valve's design team recently, it's obvious the basic topic was 'how big can we go?'
The Deck has a 40Wh (or 5,313mAh) battery inside it, but it's of a slightly strange L-shaped design. If you check out the excellent iFixit teardown of the device you'll see the X-ray shot they took of it, which clearly shows the two-cell design where Valve has angled the battery around the limited space on offer inside the chassis.
I spoke to Greg Coomer and Jay Shaw, designers at Valve who have been, and still are, working on the Steam Deck about the limitations on the size of battery they could get into the new handheld.
«We basically put as much battery as we possibly could into a device of this size, given everything else that has to fit into it,» says Coomer. «So, you know, obviously, we wanted the most battery that we could fit.»
But as there were plans for different tiers of Steam Deck—with a budget, mid-range, and high-end option—I was curious whether there had ever been plans to add in higher capacity batteries alongside higher capacity storage options.
«We didn't really talk much about having the battery itself vary between the versions of Steam Deck, when we were considering what things could differ between those models,» Coomer says. «We mostly talked about other things. We considered memory, but we didn't really have an array of APUs to choose from—we were able to produce one of those—so it wasn't really an option to have there
