Valve puts as many batteries as possible into the Steam deck

Battery life on the Steam Deck has been a key topic of discussion prior to launch and when we actually got our hands on Valve’s handheld gaming PC. That’s obviously a key talking point for designers when they’re outlining what they’ll be able to cram into the deck. From recent conversations with two of Valve’s design teams, it’s clear that the basic topic is “how far can we go?”

There’s a 40Wh (or 5,313mAh) battery inside the deck, but its L-shaped design is a bit odd.if you look at Excellent iFixit Teardown You’ll see the X-rays they took, which clearly show the dual-battery design, with Valve raking the batteries around the limited space provided within the case.
