Steam surface battery: performance, capacity and replacement

The battery in the Valve “Steam Deck” laptop is the same for all three variants. Here at GIGA you can see how long you can gamble on the go, all the other technical details and whether you can change the battery in case it runs out later.

How long does the battery last?

Depending on the complexity of the game and how much it requires hardware, battery endurance varies greatly. While you can play a 2D indie game for hours at a time, the graphics-rich Triple A title will drain your battery faster. The Official information from Valve the promise between 2 to 8 hours of playing time Under the pre-installed operating system.

Do you want to change the Steam Deck battery?

Valve recommends that its customers not open the Steam Deck and even states that it is easier to access an SSD “Not intended for exchange by end user” he is. If you open the device yourself, you always risk losing the warranty.

To make matters worse, the battery in the review devices very sticky I was. Even praise the repair page iFixit “Steam Deck” for its general restorative properties, but battery replacement in particular is needlessly complicated – iFixit even goes so far as to call it the “Achilles heel” of the “Steam Deck”. Here the question remains open about whether Valve accepts criticism and makes it easier to change the battery in subsequent hardware reviews.
